[0028] Specifically, Figure 1 As shown, a skin temperature detection unit 10 is provided on the skin 1, and the skin temperature detection unit 10 is used to detect the surface temperature of the skin 1 and transmit the temperature signal to the control unit 6. The skin heat exchange unit 2 is connected to the skin 1 and can exchange heat with the skin 1. The fluid circulation pipeline 7 is used to connect the skin heat exchange unit 2, the power unit 3, the airborne heat source 4, the airborne cold source 5, etc.; specifically, the fluid circulation pipeline 7 includes a circulation main line, a first circulation branch and a second circulation branch, the first circulation branch and the second circulation branch are connected in parallel to the circulation main line, wherein the circulation main line connects the skin heat exchange unit 2 and the power unit 3 in series, the airborne heat source 4 and the airborne heat source regulating valve 8 are arranged in series on the first circulation branch, and the airborne cold source 5 and the airborne cold source regulating valve 9 are arranged in series on the second circulation branch; the power unit 3 can use a pump, and the power unit 3 can provide power for the fluid circulation, and the fluid heated by the airborne heat source 4 or cooled by the airborne cold source 5 is sent into the skin heat exchange unit 2 through the fluid circulation pipeline 7 to achieve temperature regulation of the surface of the skin 1, and the fluid is sent back to the airborne heat source 4 or the airborne cold source 5 after completing heat exchange in the skin heat exchange unit 2.

[0029] Furthermore, the control unit 6 is respectively connected to the skin temperature detection unit 10, the power unit 3, the airborne heat source regulating valve 8 and the airborne cold source regulating valve 9, and is used to control the start and stop and speed of the power unit 3 and the opening of the airborne heat source regulating valve 8 and the airborne cold source regulating valve 9 according to the temperature signal of the skin temperature detection unit 10.

[0030] In a preferred embodiment of the present application, the skin heat exchange unit 2 can be designed to fit closely with the skin 1, or the contact surface between the skin heat exchange unit 2 and the skin 1 can directly replace the skin 1 at that position, and together with the skin 1 at other positions form the shape of the aircraft.

[0031] In a preferred embodiment of the present application, the skin heat exchange unit 2 is not limited to one, and a plurality of skin heat exchange units 2 may be arranged in series on the fluid circulation pipeline 7. A plurality of skin heat exchange units 2 are arranged in parallel on the skin 1.

[0032] In the skin temperature control system of the present application, the control unit 6 collects the temperature signal of the skin temperature detection unit 10:

[0033] a. When the surface temperature of the skin 1 is higher than the set value: the control unit 6 outputs a signal to control the onboard heat source regulating valve 8 to close, the onboard cold source regulating valve 9 to open, and the power unit 3 to start and run at the initially set speed; the control unit 6 outputs a signal to adjust the opening of the onboard cold source regulating valve 9 and the speed of the power unit 3 according to the rate of change of the surface temperature of the skin 1; when the opening of the onboard cold source regulating valve 9 is at the maximum and the speed of the power unit 3 is at the maximum and the surface temperature of the skin 1 cannot be cooled down to within the set range, the control unit 6 sends an alarm signal;

When the surface temperature of the skin 1 is lower than the set value: the control unit 6 outputs a signal to control the onboard heat source regulating valve 8 to open, the onboard cold source regulating valve 9 to close, and the power unit 3 to start and run at the initially set speed; the control unit 6 outputs a signal to adjust the opening of the onboard heat source regulating valve 8 and the speed of the power unit 3 according to the rate of change of the surface temperature of the skin 1; when the opening of the onboard heat source regulating valve 8 is at the maximum and the speed of the power unit 3 is at the maximum and the surface temperature of the skin 1 still cannot be raised to within the set range, the control unit 6 sends an alarm signal;

[0035] c. When the surface temperature of the skin 1 is within the set range, the control unit 6 outputs a signal to control the onboard heat source regulating valve 8 to close, the onboard cold source regulating valve 9 to close, and the power unit 3 to stop running.
