Working principle of hydraulic cooling fan
Jul 11 , 2024
The core of the hydraulic cooling fan is the hydraulic drive system. The hydraulic pump pressurizes the hydraulic oil and transfers it to the hydraulic motor to drive the fan blade to rotate at high speed. In this way, the fan can produce a strong airflow, quickly take away the heat, to achieve the purpose of efficient heat dissipation. This design allows the hydraulic cooling fan to operate stabl...

What is a hydraulic cooling fan?
Jul 08 , 2024
Hydraulic cooling fan is a kind of efficient cooling equipment driven by hydraulic system. Unlike the traditional electric cooling fan, the hydraulic cooling fan uses the liquid pressure generated by the hydraulic pump to drive the fan blade to rotate, resulting in a strong airflow for heat dissipation. Advantages of hydraulic cooling fan High performance: The hydraulic system provides powerful po...

What kind of design cooling fan can read the tach signal through GPIO？
Jun 17 , 2024
Typically, the cooling fan is connected to the system through a three-wire interface, which includes a power cable, a ground cable, and a Tach cable (speed signal cable). In order to be able to read Tach signals through GPIO, you need to select a fan that supports this feature. Such fans are often referred to as "ach-enabled" (supporting Tach) or "RPM-sensing" (supporting speed detection) fans. Th...

Is the cooling effect of the cooling fan related to the number of fan blades？
Jun 03 , 2024
The cooling effect of the cooling fan is indeed related to the number of fan blades, but this is only one of the influencing factors. Here's a detailed explanation: 1. Wind pressure Wind pressure: More blades generally provide higher wind pressure, which is beneficial for cooling scenarios that require high wind pressure. 2. Blade design Shape and Angle: Optimized blade design allows for better ai...

How does the temperature sensing element of the temperature control cooling fan work?
May 30 , 2024
Then the previous article continues to say how the temperature sensing element of the temperature control cooling fan works. Take a dc cross flow fan for example, the fan control circuit will adjust the speed and power of the fan according to the signal from the temperature sensing element. When the temperature exceeds the threshold, the fan will operate at the maximum power to enhance the heat di...
