[0024] Embodiment 1

[0025] This embodiment provides an automatic heat dissipation system for the engine compartment;

[0026] like Figure 1 and Figure 2 As shown, an automatic cooling system for an engine compartment includes:

[0027] A main controller, wherein the main controller is connected to the temperature sensor and the engine compartment switch respectively;

[0028] The main controller is also connected to a cooling fan;

[0029] The temperature sensor is arranged inside the engine compartment and is used to detect the ambient temperature inside the engine compartment and upload the detection data to the main controller;

[0030] The main controller receives engine compartment internal temperature data and engine compartment switch status data, and the main controller determines whether to turn on a cooling fan disposed inside the engine compartment according to the engine compartment internal temperature and the engine compartment switch status.

[0031] Furthermore, the system further comprises:

[0032] The main controller determines whether to turn off the cooling fan disposed inside the engine compartment according to the temperature data inside the engine compartment or the working time of the cooling fan.

[0033] Furthermore, the system further comprises:

[0034] After turning off the cooling fan, the main controller continuously collects and transmits the internal ambient temperature data of the engine compartment and the switch status data of the engine compartment, and determines whether to turn on the cooling fan set inside the engine compartment according to the internal temperature of the engine compartment and the switch status of the engine compartment.

[0035] Furthermore, the heat dissipation fan allows the heat dissipation working mode to be turned on manually.

[0036] Furthermore, the cooling fan allows the operating state to be turned on through control logic or control signals.

[0037] Further, the main controller determines whether to turn on the cooling fan disposed inside the engine compartment according to the temperature inside the engine compartment and the switch state of the engine compartment, specifically including:

[0038] When the temperature inside the engine compartment is higher than a set threshold and the transmitter compartment switch state is on, the cooling fan arranged inside the engine compartment is turned on; otherwise, the cooling fan is not turned on.

[0039] Further, the main controller determines whether to turn off the cooling fan disposed inside the engine compartment according to the temperature data inside the engine compartment or the working time of the cooling fan, specifically including:

[0040] When the temperature inside the engine compartment is lower than a set threshold, or the working time of the cooling fan exceeds a set threshold, the cooling fan arranged inside the engine compartment is turned off.

[0041] When the engine compartment ambient temperature sensor detects that the engine compartment ambient temperature has reached a certain temperature, there is a risk of burns if the engine compartment is opened for maintenance. At the same time, the maintenance personnel turn on the engine compartment switch, and the main controller determines that the cooling fan needs to be turned on based on the engine compartment ambient temperature and the engine compartment switch status, and controls the cooling fan to turn on to dissipate heat and cool the engine compartment. When the engine compartment ambient temperature drops to a certain temperature, it is an appropriate temperature for maintenance, and the main controller determines that the cooling fan can be turned off and controls the cooling fan to turn off.

[0042] Automatically and in advance cooling down the ambient temperature of the engine compartment can reduce the time waiting for cooling during maintenance; it can also avoid the risk of burns during high-temperature maintenance; and it can also reduce the aging of wiring harnesses and components in the engine compartment caused by long-term high temperatures.
