[0028] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0029] Embodiment 1:

[0030] A cold air circulation system of a combustion engine control cabinet 2 includes: a thermoelectric cooler 3, a first temperature sensor 1, a second temperature sensor 7, and a guide cover. Figure 2As shown, the thermoelectric cooler 3 is installed on the outer surface of the side wall of the burner control cabinet 2, and the air outlet 5 and the return air outlet 4 are correspondingly opened on the inner surface of the side wall of the control cabinet corresponding to the air outlet and the air inlet of the thermoelectric cooler 3, and the air outlet 5 is located at the lower part, and the return air outlet 4 is located at the upper part. The cold air cooled by the air outlet of the thermoelectric cooler 3 enters the inside of the control cabinet from the air outlet 5, circulates inside the control cabinet, and then re-enters the thermoelectric cooler 3 through the return air outlet 4 and the air inlet for cooling, realizing cyclic cooling.

[0031] Since the air outlet 5 and the return air outlet 4 are both located on the left side of the cabinet, and the distance between the upper and lower air outlets is small, most of the cold air enters the control cabinet directly into the return air outlet 4 during operation, and the cold air cannot be effectively recycled. Figure 3 As shown, a deflector is installed on the air outlet 5, and the deflector includes a base 8 and a deflector pipe 9 fixedly installed therewith. The base 8 is a square structure with upper and lower openings, and a connecting plate 81 is provided on one side where the base 8 is connected to the side wall. The base 8 is connected to the cabinet side wall through the connecting plate 81, and the connection method is bolt connection or welding. The deflector pipe 9 is a square structure, made of PE plastic film, and the length of the deflector pipe 9 does not exceed three quarters of the burner control cabinet 2, leaving a certain distance for the incoming air to circulate.

[0032] The first temperature sensor 1 is installed outside the burner control cabinet 2 to detect the indoor temperature outside the cabinet, and the second temperature sensor 7 is installed inside the burner control cabinet 2 to detect the temperature inside the cabinet. Figure 1 As shown, the first temperature sensor 1 , the second temperature sensor 7 , the thermoelectric cooler 3 and the controller 6 of the burner control cabinet 2 are electrically connected.

[0033] The first temperature sensor 1 and the second temperature sensor 7 detect the temperature inside and outside the cabinet in real time and transmit it to the controller 6. The temperature control mode of the controller 6 is automatic adjustment: heating is performed when the temperature is lower than 5°C, and cooling is performed when the temperature is higher than 30°C. When the first temperature sensor 1 detects that the outdoor temperature is higher than 30°C, the controller 6 enables the thermoelectric refrigerator 3 to cool, and the cold air enters the control cabinet from the air outlet 5. After the cold air circulates inside the control cabinet, it re-enters the thermoelectric refrigerator 3 through the return air port 4 and the air inlet for cooling, thus realizing cyclic cooling. During normal operation, the ambient temperature of the burner control cabinet 2 can reach 45°C. After the electric refrigerator is installed, the temperature at the farthest end of the burner control cabinet 2 drops to 27°C, effectively reducing the failure rate of the burner control cabinet 2.

[0034] Embodiment 2:

[0035] A cold air circulation system of a combustion engine control cabinet 2 includes: a thermoelectric cooler 3, a first temperature sensor 1, a second temperature sensor 7, and a guide cover. Figure 2As shown, the thermoelectric cooler 3 is installed on the outer surface of the side wall of the burner control cabinet 2, and the air outlet 5 and the return air outlet 4 are correspondingly opened on the inner surface of the side wall of the control cabinet corresponding to the air outlet and the air inlet of the thermoelectric cooler 3, and the air outlet 5 is located at the lower part, and the return air outlet 4 is located at the upper part. The cold air cooled by the air outlet of the thermoelectric cooler 3 enters the inside of the control cabinet from the air outlet 5, circulates inside the control cabinet, and then re-enters the thermoelectric cooler 3 through the return air outlet 4 and the air inlet for cooling, realizing cyclic cooling.

[0036] Since the air outlet 5 and the return air outlet 4 are both located on the left side of the cabinet, and the distance between the upper and lower air outlets is small, most of the cold air enters the control cabinet directly into the return air outlet 4 during operation, and the cold air cannot be effectively recycled. Figure 4 As shown, a deflector is installed on the air outlet 5, and the deflector includes a base 8 and a deflector pipe 9 fixedly installed therewith. The base 8 is a square structure with upper and lower openings, and a connecting plate 81 is provided on one side where the base 8 is connected to the side wall. The base 8 is connected to the cabinet side wall through the connecting plate 81, and the connection method is bolt connection or welding. The deflector pipe 9 is an "L"-shaped structure, made of PE plastic film, and includes a horizontal pipe and a vertical pipe. The vertical pipe is perpendicular to the horizontal pipe, and the vertical pipe output port is arranged opposite to the return air port 4. The cold air is discharged to the bottom of the cabinet through the deflector pipe 9 and then moves upward, further increasing the circulation air path of the cold air and improving the cooling effect of the cold air.

[0037] The first temperature sensor 1 is installed outside the burner control cabinet 2 to detect the indoor temperature outside the cabinet, and the second temperature sensor 7 is installed inside the burner control cabinet 2 to detect the temperature inside the cabinet. Figure 1 As shown, the first temperature sensor 1 , the second temperature sensor 7 , the thermoelectric cooler 3 and the controller 6 of the burner control cabinet 2 are electrically connected.

[0038] The first temperature sensor 1 and the second temperature sensor 7 detect the temperature inside and outside the cabinet in real time and transmit it to the controller 6. The temperature control mode of the controller 6 is automatic adjustment: heating is performed when the temperature is lower than 5°C, and cooling is performed when the temperature is higher than 30°C. When the first temperature sensor 1 detects that the outdoor temperature is higher than 30°C, the controller 6 enables the thermoelectric refrigerator 3 to cool, and the cold air enters the control cabinet from the air outlet 5. After the cold air circulates inside the control cabinet, it re-enters the thermoelectric refrigerator 3 through the return air port 4 and the air inlet for cooling, thus realizing cyclic cooling. During normal operation, the ambient temperature of the burner control cabinet 2 can reach 45°C. After the electric refrigerator is installed, the temperature at the farthest end of the burner control cabinet 2 drops to 27°C, effectively reducing the failure rate of the burner control cabinet 2.
