[0023] The following, in conjunction with the accompanying drawings, will make the technical solutions and other beneficial effects of the present invention apparent through a detailed description of the specific embodiments of the present invention. The accompanying drawings are provided for reference and illustration only and are not intended to limit the present invention. The dimensions shown in the accompanying drawings are only for the convenience of clear description and do not limit the proportional relationship.

[0024] Example:

[0025] Please refer to Figure 1 and Figure 2 As shown, the head skin thermal management system provided by the present invention comprises a heat exchange cap 5, an elastic cap 4, a headscarf 6, a composite cable 2 and a control host 3. The wearing effect is shown in FIG. Figure 1 The heat exchange cap 5 is provided with low-temperature refrigerant inlet and outlet 501 and 503 , and a temperature sensor 503 .

[0026] Please refer to Figure 3 As shown, the heat exchange cap 5 is composed of two fan-shaped heat exchangers 505, 506 and a rectangular heat exchanger 507. The fan-shaped heat exchangers 505 and 506 are symmetrical structures. The three heat exchangers 505, 506 and 507 are connected in series through hoses 508 and 509. When the refrigerant flows in from the hose 501, it passes through the heat exchangers 505, 506 and 507 and flows out through the hose 502, and vice versa.

[0027] Please refer to Figure 4 As shown, the arc-shaped long sides of the fan-shaped heat exchangers 505 and 506 are respectively connected to the two long sides of the rectangular heat exchanger 507 to form a heat exchange cap 5, which is fitted on the head.

[0028] Please refer to Figure 5 As shown, the composite cable 7 includes a plug cable assembly 701 and a socket cable assembly 702. The hoses 711, 712 and the wire 713 in the plug cable assembly 701 are respectively connected to the hoses 501, 502 of the fan-shaped heat exchangers 505 and 506 and the temperature sensor 503 of the rectangular heat exchanger 507.

[0029] Please refer to Figure 6 As shown, the socket 720 of the socket cable assembly 702 is composed of two pipes and three wire terminals. Through the coupling of the socket 720 with the plug of the plug cable assembly 701, the hoses 711 and 712 are respectively connected to the soft hoses 721 and 722, and the wires 713 and 723 are electrically connected.

[0030] Please refer to Figure 7 As shown, the control host 3 includes a compressor 301 , a water tank evaporator assembly 302 , a water pump 303 , a radiator 304 , a controller 305 and a cabinet 300 .

[0031] Please refer to Figure 8 As shown, a socket 720 of a socket cable assembly 702 is installed on the back of the control host 3 .

[0032] When the head skin thermal management system of the present invention is in operation, the compressor 301 performs work to cool the refrigerant in the water tank evaporator assembly 302 to a low temperature, and the water pump 303 pumps the low-temperature refrigerant through the socket cable assembly 702 and the plug cable assembly 701 to the heat exchange cap 5 for heat exchange, thereby reducing the head skin temperature. When the controller 305 detects that the temperature reaches the set temperature through the temperature sensor 503 located on the rectangular heat exchanger 507, the compressor 301 stops working. When the head skin temperature is reduced, the condensed water generated is absorbed by the headscarf 6. When the head skin is cooled at a low temperature, it will cause blood vessels to contract, limiting the amount of chemotherapy drugs reaching the hair follicles, thereby avoiding or reducing the damage of the hair follicles by the drugs to prevent hair loss.
