Problems solved by technology

[0002] The bus bar is a relay station on the main board that is used to collect all data and transmit it. During the operation of the system, the power module and the main control module are usually connected to supply power through the power connector or power cable. Due to the current The power supply current is getting bigger and bigger, and the busbar is more and more widely used, and the heating problem of the busbar when it supplies power over a long distance is becoming more and more prominent. Therefore, the heat dissipation problem of the busbar is becoming more and more urgent. The heat dissipation safety of the busbar must be considered when the power supply is powered at high power, and corresponding control methods must be adopted; in the prior art, the heat dissipation of the busbar is mainly determined by the temperature sensor to detect the temperature, but due to the influence of the medium, the temperature The response time and accuracy of the sensor cannot be reached, and it is difficult to adjust the heat dissipation device in time to achieve the purpose of reducing the temperature, especially when the power supply is powered by high power, the heat dissipation safety of the bus bar cannot be guaranteed.

Embodiment 1

[0032] Such as figure 1 As shown, a method for regulating and controlling the heat dissipation of busbars comprises the following steps:

[0033] Step S101: Use the voltage detection sensor as the detection element in this embodiment, detect the voltage drop value at the preset working point at both ends of the bus bar through the voltage detection sensor, and take the detected voltage drop value as ΔP.

[0034] Step S102: preset voltage drop value: P0, compare the detected voltage drop value ΔP with the preset voltage drop value P0, and obtain the voltage drop difference P, namely: P=P0-ΔP; according to the voltage drop difference The size of the value P determines the heating state of the bus bar, that is, adjusts the PWM signal that needs to be output to the cooling fan, adds the difference P of the voltage drop to the PWM control circuit, and outputs the corresponding PWM signal to the cooling fan by adjusting the duty cycle. Fan control IC.
