Description

[Technical field]

[0001] The present invention relates to the technical field of fan detection, and in particular to a system and method for detecting fan function by partial pressure. [Background technology]

[0002] At present, our laptops or desktop computers generally use fans for heat dissipation. When the laptop or desktop computer is turned on and running normally, its internal motherboard will generate heat and generate a lot of heat. If this heat is not well cooled or discharged, it is easy to burn the motherboard of the computer. Therefore, it is necessary to set a fan inside the computer host. The fan disperses the heat inside the computer, protects the host, and greatly extends the service life of the computer.

[0003] At present, the method for testing the cooling function of the fan is to manually connect the fan's connection circuit to the power supply directly or to assemble the fan into the whole machine for functional testing. However, this detection method does not perform functional testing of the fan under different output voltages, and is not suitable for different types of fans. At the same time, assembling the fan into the whole machine for testing is time-consuming and labor-intensive, and it is easy to cause a circuit short circuit due to the fan's inability to withstand the change in output voltage, resulting in a decrease in fan quality and even certain safety hazards.

[0004] In view of this, it is necessary to provide a system and method for detecting fan function by voltage division to solve the problems of the current detection method, such as being time-consuming and labor-intensive, causing circuit short circuits due to the fan itself being unable to withstand changes in output voltage, being unsuitable for different types of fans, reducing fan quality, and posing safety hazards. [Summary of the invention]

[0005] The purpose of the present invention is to provide a system and method for detecting fan function by voltage division, so as to solve the problems of the current detection method, such as being time-consuming and labor-intensive, causing circuit short circuit due to the fan itself being unable to withstand changes in output voltage, being unsuitable for different types of fans, reducing fan quality, and posing safety hazards.

[0017] The present invention also provides a method for detecting fan function by pressure division, which comprises the following steps:

[0018] (1) The circuit is connected in series with a power supply, a PCB board, a sliding rheostat, a fan and a voltmeter;

[0019] (2) Turn on the power supply;

[0020] (3) The sliding rheostat adjusts the input voltage to a first voltage;

[0021] (4) the voltmeter measures the actual input voltage of the fan as a first voltage;
