(Summary description)What is the relationship between the wind pressure and air volume of the cooling fan There is a close relationship between the wind pressure and air volume of a cooling fan, and generally it has the following characteristics: Basic relationship: Within a certain range, when the speed and other conditions of the fan remain unchanged, the air pressure increases and the air volume usually decreases; On the contrary, as the wind pressure decreases, the air volume will increase. This is because the power of the fan is limited, and when greater resistance needs to be overcome (i.e., generating higher wind pressure), the energy used to drive air flow will relatively decrease, resulting in a decrease in air volume. Performance curve: The relationship between wind pressure and air volume of a fan can be represented by a performance curve. A typical fan performance curve is a downward sloping curve, with the horizontal axis representing air volume and the vertical axis representing air pressure. At the beginning stage of the curve, as the air volume increases, the decrease in air pressure is relatively slow; But when the air volume increases to a certain extent, the air pressure will sharply decrease. The performance curve of fans of different types and specifications will vary, depending on factors such as fan structure, impeller shape, and speed. Influencing factors: The impeller diameter, speed, blade shape, and angle of the fan can all affect the relationship between wind pressure and air volume. For example, increasing the diameter of the impeller or increasing the speed can usually increase both the wind pressure and air volume, but this increase is also limited by factors such as motor power and fan structural strength. In addition, the shape and angle of the blades determine the way the fan exerts force on the air. Optimizing blade design can improve the wind pressure air flow characteristics to a certain extent, enabling the fan to operate more efficiently under different working conditions. In practical life applications, the nominal maximum air volume value is not the actual air supply obtained by the fan heating plate, and strong ventilation capacity does not necessarily mean a large air volume. When air flows, the airflow will encounter obstruction from the fan or component in its flow path, and its impedance will limit the free flow of air. When the air volume increases, the air pressure will decrease. What are the effects of high air pressure in the cooling fan on the system? Component damage: Excessive wind pressure can subject components such as air ducts and radiators to significant pressure. Prolonged exposure to this condition can cause deformation, cracking, or loosening of these components, reducing their lifespan and even leading to premature scrapping, affecting the normal operation of the entire cooling system. Excessive heat dissipation: If the wind pressure is too high and the air volume far exceeds the actual heat dissipation requirements of the system, it will cause the temperature of the cooled equipment to be too low, which may have adverse effects on the normal operation of the equipment. For example, some electronic devices may experience performance instability, component parameter changes, and other issues at excessively low temperatures. Increased noise: Excessive wind pressure can cause the fan to produce greater noise during operation. On the one hand, the friction between the fan impeller and the air intensifies, resulting in sharp airflow noise; On the other hand, greater pressure and vibration on fan components can also lead to increased mechanical noise. Excessive noise not only affects the working environment, but may also pose a threat to the physical and mental health of operators.
