[0019] Ice bag 1, circulating water pipe 2 and micro pump 3; the circulating water pipe 2 is a serpentine coil and is arranged as an upper and lower double-layer structure. After the ice bag 1 covers the lower half of the circulating water pipe 2, the middle pipe body of the circulating water pipe 2 penetrates the top wall of the ice bag 1 and is sealed at the connection with the top wall. The content of the circulating water pipe 2 is a liquid with a low freezing point and low specific heat capacity. The water inlet and outlet of the micro pump 3 are respectively connected to the two ends of the circulating water pipe 2. The ice bag 1 is filled with a heat exchange filler; the heat exchange filler is a mixture of sodium polyacrylate and water; the variable frequency power supply 5 is provided with a power interface 6.

[0020] Semiconductor refrigeration sheet 4, heat dissipation structure and variable frequency power supply 5; the cooling surface of semiconductor refrigeration sheet 4 is arranged on the upper side of circulating water pipe 2, and the heat dissipation structure is arranged on the heat dissipation surface; micro pump 3 and semiconductor refrigeration sheet 4 are electrically connected to variable frequency power supply 5 respectively; the heat dissipation structure is heat dissipation fan 9, and heat dissipation fan 9 is electrically connected to variable frequency power supply 5.

[0021] The binding structure is used to bind and fix the ice pack 1 on the human body; the binding structure includes a wrapping bag 8 and a Velcro bandage 7; one side of the wrapping bag 8 is open and tightly wrapped on the ice pack 1, a pair of Velcro bandages 7 are arranged along the wrapping bag 8 in a mirror image, and the movable ends of the two Velcro bandages 7 are connected by Velcro bonding.

[0022] The variable frequency power supply 5, semiconductor cooling sheet 4, cooling fan 9, etc. used in the present invention are all prior arts well known to those skilled in the art, and their use and control methods are all prior arts.

[0023] In the specific implementation of this embodiment:

[0024] The cooling fan 9 is composed of a radiator and an axial flow fan, and the radiator is a heat sink structure, and thermal conductive silicone grease is coated between the cooling fan 9 and the semiconductor refrigeration sheet 4; the power interface 6 can adopt the common Type-C interface, and the external power supply can use a common power bank, etc., to increase the practicality of the present invention; when in use, put the pre-frozen ice bag 1 into the wrapping bag 8, with the fan facing outward, and fix it to the part of the body that needs cold compress through the Velcro bandage 7. If necessary, a bandage with multiple wrapping bags 8 can be selected, and multiple refrigeration equipment can be placed on the bandage to improve applicability; the circulating water pipe 2 can be filled with high-concentration alcohol, which has a small specific heat capacity and a low freezing point, so the temperature rises and falls quickly, and it will not freeze. Ice can meet the use requirements. The micro pump 3 drives the liquid inside the circulating water pipe 2 to circulate unidirectionally, and the circulating liquid cooled on the cooling surface of the semiconductor refrigeration plate 4 is transported to the inside of the ice bag 1 to keep the ice bag 1 at a lower temperature.
