[0019] The technical scheme of the utility model will be clearly and completely described below in combination with embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] It is explained that the orientation concepts of "left", "right", "up", "down", "front", "back", "inner" and "outer" in the following schemes are relative directions, which will not be listed one by one.

[0021] A composite radiator, referring to Figure 1 , comprises a phase change material 1. The phase change material 1 is selected from materials with good phase change characteristics and stability, such as paraffin, for absorbing a large amount of heat generated inside the equipment and realizing phase change, so as to reduce the equipment temperature.

[0022] A semiconductor refrigeration sheet 4 is arranged on the left side of the phase change material 1. The semiconductor refrigeration sheet 4 further reduces the temperature of the equipment by generating a refrigeration effect, so as to improve the heat dissipation efficiency. Heat insulation pads are arranged between the hot end and the cold end of the semiconductor refrigeration sheet 4 to avoid direct heat transfer in the semiconductor, which affects the heat dissipation efficiency and the refrigeration efficiency. The first heat dissipation fin 5 is arranged in close contact with the left side of the semiconductor refrigeration sheet 4. The first heat dissipation fin 5 quickly transfers the heat generated by the semiconductor refrigeration sheet 4 to the external environment to reduce the equipment temperature. In order to achieve faster heat transfer, a heat pipe or liquid cooling can be used to bring it to a farther place.

[0023] A thermoelectric conversion module 3 is located on the right side of the phase change material 1. The thermoelectric conversion module 3 converts the waste heat released by the phase change material 1 into electrical energy output, realizing waste heat reuse. A heat insulation material 2 is placed between the thermoelectric conversion module 3 and the phase change material 1 to prevent the thermoelectric conversion module 3 from starting to operate before the phase change material 1 has fully released its heat, thus affecting the efficiency of the electrical energy output. A second heat sink 6 is attached to the right side of the thermoelectric conversion module 3. The second heat sink 6 is used for heat dissipation to ensure the normal operation of the cold end of the thermoelectric conversion module 3. To improve the heat dissipation efficiency of the cold end, heat pipes or liquid cooling can also be used to dissipate the heat to a more distant location.

[0024] refer to Figure 2 When electronic devices generate heat, phase change material 1 absorbs a large amount of heat generated inside the device to achieve phase change, thereby reducing the device temperature; thermoelectric conversion module 3 can convert the waste heat released by phase change material 1 into electrical energy output, realizing the reuse of waste heat; semiconductor cooling chip 4 can further reduce the device temperature by generating a cooling effect, thereby improving heat dissipation efficiency.

[0025] In this process, the thermal insulation material 2 is placed between the phase change material 1 and the thermoelectric conversion module 3 mainly to prevent the thermoelectric conversion module 3 from starting to work before the phase change material 1 has fully released its heat, thus affecting the efficiency of power output. Meanwhile, the cold end of the semiconductor cooling chip 4 is in close contact with the phase change material 1 and generates a cooling effect by absorbing the heat released by the phase change material 1. At the same time, the hot end of the semiconductor cooling chip 4 is in close contact with the first heat sink 5, which quickly transfers the heat generated by the semiconductor cooling chip 4 to the external environment.

[0026] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above description or the technology or knowledge in related fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
