Selection of SanAce Cooling Fan

Selection of SanAce Cooling Fan From the theory of heat transfer, it can be seen that increasing the convective heat transfer coefficient can effectively enhance heat transfer, while intensifying fluid flow (increasing flow velocity) can effectively improve the convective heat transfer coefficient. A fan is a component designed to enhance air flow. The commonly used fans in the field of electronic cooling include axial fans and centrifugal fans, as shown in the figure. The inlet and outlet of an axial fan are parallel, characterized by high air volume, low air pressure, and low noise, making it suitable for situations with low wind resistance but high air volume requirements; A centrifugal fan is a fan whose inlet and outlet are perpendicular, with low air volume and high air pressure, making it suitable for situations with high air resistance and low air demand. In industry, there are also Diagonal Fans, also known as Diagonal Fans or Tangential Fans. Figure a) Parallel inlet and outlet surfaces of axial fans b) Vertical inlet and outlet surfaces of centrifugal fans When selecting a fan, the core parameters that need to be considered are as follows: 1) Geometric dimensions; 2) Air volume demand: The amount of air that the fan can provide; 3) System resistance and the wind pressure that the fan can provide; 4) Fan speed control method; 5) Noise requirements; 6) Application environment and equipment lifespan; 7) Cost.

What is the difference between the IP68 and salt spray prevention of SanAce cooling fans

What is the difference between the IP68 and salt spray prevention of SanAce cooling fans The IP68 waterproof rating and salt spray corrosion resistance of the fan are two different protection standards, which are respectively used for the protection ability under different environmental conditions. IP68 is an international protection level standard, where "IP" represents international protection. The number "6" represents the level of protection against solid objects, while the number "8" represents the level of protection against liquids. IP68 indicates that this fan has high dust and water resistance. Specifically, it can prevent the entry of dust and work continuously at specific water depths. Anti salt spray corrosion usually refers to the product having the ability to resist corrosion in seawater or environments containing salt. The anti-corrosion ability of the cooling fan means that it has undergone special design or coating treatment, which can lower the corrosion of its metal components caused by salt in seawater. This is crucial for equipment used in marine environments, as salt in seawater can lead to metal corrosion, affecting the lifespan and performance of the equipment. The IP68 waterproof rating mainly focuses on the protective ability of the cooling fan against water and dust, while anti salt spray is more focused on resisting the corrosion of metal components caused by salt in seawater.

How to choose the appropriate cooling fan based on device power consumption and power supply

How to choose the appropriate cooling fan based on device power consumption and power supply Cooling fans play a crucial role in electronic devices, ensuring the normal operation of the equipment by removing heat from the inside. When selecting a suitable cooling fan, it is necessary to comprehensively consider the power consumption of the device and the power supply capacity. Here are some suggestions to help you choose the appropriate cooling fan based on these factors. 1、 Understand the power consumption of the device Firstly, it is necessary to understand the power consumption of the device. Power consumption refers to the energy consumed by a device during operation. Different devices have different power consumption, depending on their hardware configuration and operating status. In order to choose a suitable cooling fan, it is necessary to understand the actual power consumption of the device in order to choose a cooling fan with sufficient power. 2、 Consider the power supply capacity Secondly, it is necessary to consider the power supply capacity. Power supply is a device that provides energy in electronic devices, and its supply capacity directly affects the normal operation of the equipment. When selecting a cooling fan, it is necessary to understand the power supply capacity to ensure that the cooling fan can receive sufficient power supply. If the power supply capacity is insufficient, it may lead to unstable or abnormal operation of the cooling fan. 3、 Matching power consumption and power supply capacity To ensure that the cooling fan can meet the power consumption and power supply requirements of the device, it is necessary to match the two. This can be achieved by selecting a cooling fan with sufficient power. In addition, it is necessary to ensure the stable and reliable connection between the cooling fan and the power supply to ensure that the cooling fan can obtain a stable power supply. 4、 Choose the appropriate cooling fan for the device Based on the requirements of device power consumption and power supply capacity, a suitable cooling fan can be selected for the device. For example, for devices with lower power consumption, low noise and low air volume cooling fans can be selected; For devices with high power consumption, high air volume and high air pressure cooling fans can be selected. In addition, suitable types of cooling fans can be selected based on the specific needs and environmental conditions of the equipment, such as axial flow fans, centrifugal fans, or mixed flow fans. 5、 Consider other factors In addition to power consumption and power supply capacity, other factors need to be considered, such as noise level, service life, maintenance costs, etc. Choosing high-quality cooling fans can reduce noise pollution, improve the service life and reliability of equipment, and also reduce maintenance costs and risks in the later stage.

How to choose parameters such as size, speed, power, and noise of the cooling fan?

How to choose parameters such as size, speed, power, and noise of the cooling fan? In electronic devices and systems, a cooling fan is one of the essential components used for heat dissipation and air circulation. When selecting a cooling fan, multiple parameters need to be considered, including size, speed, power, and noise. These parameters have a significant impact on the performance and effectiveness of the fan. This article will provide a detailed explanation of how these parameters affect the selection of fans. 1、 Size The size of the cooling fan is one of the important factors to consider when selecting. Dimensions are usually expressed in inches or millimeters. Larger fans typically have higher heat dissipation capacity and stronger air circulation, but also require more space for installation. On the contrary, smaller fans are the opposite. Therefore, when choosing a cooling fan, it is necessary to choose the appropriate size based on the device's needs and space limitations. 2、 Speed Speed is another important parameter for measuring the performance of a cooling fan. It is usually expressed in revolutions per minute (RPM). A higher rotational speed usually means that the fan has higher heat dissipation capacity and faster air circulation speed. However, high rotational speeds also bring higher noise and energy consumption. Therefore, when choosing a cooling fan, it is necessary to choose the appropriate speed based on actual needs. 3、 Power Power is another important parameter for measuring the performance of a cooling fan. It is usually expressed in watts (W) or milliwatts (mW). A higher power means that the fan requires more energy to drive, but also has stronger heat dissipation capabilities. When selecting a cooling fan, it is necessary to consider the power consumption and cooling requirements of the device in order to select the appropriate power. 4、 Noise Noise is an important factor to consider when using a cooling fan. Louder noise may affect people's work and living environment. When selecting a cooling fan, it is necessary to consider the noise level of the fan to avoid excessive noise interference. Some fans have a silent design, which can reduce noise by reducing fan speed or changing fan structure. In summary, when choosing a cooling fan, multiple factors need to be considered, including size, speed, power, and noise. These factors have a significant impact on the performance and effectiveness of fans. By comprehensively considering these factors and selecting according to actual needs, it can be ensured that the selected cooling fan can meet the needs of the equipment and provide the best performance and usage effect.

What is the blade function of the SanAce DC cooling fan?

What is the blade function of the SanAce DC cooling fan? When it comes to DC fans, those who have understood cooling fans must know that DC fans undergo DC voltage and electromagnetic induction, converting electrical energy into machinery to drive the blades to rotate. Therefore, the fan casing and blades are essential components, and most people know that these two parts are important. So what is the role between them? Today, the SanAce DC cooling fan editor will give you a science popularization: Firstly, blade curvature: within a certain range, the larger the blade curvature, the greater the gas kinetic energy at the same speed, that is, the greater the air volume and pressure; At the same time, the greater the resistance on the blades, the greater the torque requested from the motor. Secondly, motor diameter: Due to the presence of the motor and bearings, there is inevitably a blind spot in the center of the DC fan spindle where there is no airflow passing through, and the diameter of the spindle determines the size of this blind spot. The size of the spindle diameter mainly depends on the power of the fan motor - high-power motors require larger stator winding coils, which inevitably occupy more space. In the absence of vertical expansion (increasing height), they have to expand horizontally (increasing area). SanAce DC cooling fan Thirdly, blade curvature: In addition to having a certain curvature on the cross-section, the fan blades do not extend straight along the radial direction in the overhead plane, but slightly bend in the direction of rotation, forming a certain curvature. If the blades extend straight along the radial direction, the airflow driven by the rotation of the cooling fan will be scattered on one side of the air outlet, with short air supply intervals and lack of concentration of "force"; If the current product version is slightly curved, it can ensure that the blown airflow is concentrated in the cylindrical space directly in front of the air outlet, increasing the air supply interval and air pressure. Fourth, blade spacing: If the spacing between blades is too small, it can cause airflow disturbance, increase friction on the surface of the blades, and reduce fan efficiency; Excessive spacing between blades can lead to increased pressure loss and lack of wind pressure.

Is the service life of DC fans affected by the environment

Is the service life of DC fans affected by the environment In daily life, in order to extend the service life of DC fans and reduce the cost of equipment wear and tear, we will regularly inspect and maintain the DC fans in mechanical equipment. However, as the seasons change, the surrounding environmental temperature will also change accordingly. In spring and autumn, the temperature is suitable, and the winter is icy cold and the summer is scorching hot. So, is the service life of DC fans affected by the environment? Due to the influence of its material and bearings, DC fans are indeed affected by the environment and working pressure. If the DC fan operates in a high-temperature working environment, it will accelerate the evaporation of lubricating fluid in the oil bearing, causing equipment swelling and conflicts. The coil resistance will also increase, falling into a vicious cycle of heating and scalding, which will accelerate the aging rate of electronic components. The service life of DC cooling fans will be greatly reduced. Dust can cause changes in the distribution of fan blade mass, increase conflicts, increase wind resistance, affect self heat dissipation, make it difficult to transfer heat between the heat sink and the air, and cause electrostatic discharge to damage components and equipment. The harsh usage environment may greatly reduce the effectiveness and lifespan of the fan. If the working pressure of the cooling fan is high, the faster the fan speed will be, the faster the bearing wear will be, and the stator winding coils and electronic components will generate more heat, resulting in a relatively shorter lifespan. So the temperature of the surrounding environment actually has a significant impact on the lifespan of DC fans. Therefore, we should pay more attention to the maintenance and upkeep of DC fans in our daily lives. In the hot summer, we should try to take ventilation measures for mechanical equipment. Secondly, we should purchase high-quality DC fan products. Poor quality DC fans not only affect production but also cause unnecessary trouble. In daily life, we can choose an appropriate speed to reduce fan noise by understanding the relationship between fan speed and noise level. At the same time, other measures can be taken to further reduce the noise level of the fan, such as selecting a low-noise fan, adjusting the fan speed, installing shock-absorbing foot pads, and regular maintenance.
