[0024] As Figures 1-6As shown, a heat dissipation device suitable for electrical components, comprising a housing 1, the housing 1 inside the installation of the bracket 2, the bracket 2 on the installation of electrical components 3, the bottom of the electrical components 3 installed refrigeration module 8. The bracket 2 on one side of the position of the installation of the fan group 10, high-speed rotating fan blade stirring instrument air flow, make uneven temperature field to speed up the exchange rate, effectively improve the uneven temperature distribution phenomenon, to achieve the purpose of uniform temperature.

[0025] The refrigeration module 8 includes the bottom of the electrical components 3 of the heat conducting block 801, the top structure of the refrigeration module is the high thermal conductivity of the heat conducting block, used to absorb the heat generated by the electrical components 3 in the work of FPGA module, specifically, the high thermal conductivity of the heat conducting block can adopt copper aluminum combination heat conducting block, which will be copper and aluminum perfect combination of a certain process, let copper quickly heat transfer to aluminum, and then by the large area of aluminum heat dissipation, which not only increases the aluminum thermal conductivity than copper, but also makes up for the copper heat dissipation than aluminum, organic combination to achieve the effect of rapid heat transfer and rapid heat dissipation.

[0026] The lower end of the heat-conducting block 801 is attached with a TEC semiconductor refrigeration sheet 802, which uses the Peltier effect to refrigerate, and the cold end is attached to the heat-conducting block 801, so that the heat of the heat-conducting block 801 can be quickly reduced. An electric resistance temperature sensor is mounted on the heat-conducting block 801, and the sensor is connected to the temperature control panel 5, so that the temperature of the heat-conducting block 801 can be accurately controlled. The lower end of the TEC semiconductor refrigeration sheet 802 is provided with a liquid cooling head 803, which is connected to the cold liquid inlet end 6 through a cold liquid inlet pipe 804 and connected to the cold liquid outlet end 7 through a cold liquid outlet pipe 805. Through the heat exchange of the cold liquid, the heat on the TEC semiconductor refrigeration sheet 802 is effectively reduced. The pipeline in the liquid cooling head 803 is laid in a serpentine shape, which can increase the contact area and then more efficiently absorb the heat of the hot end of the TEC semiconductor refrigeration sheet 802. Specifically, in this embodiment, the pipeline is distributed in an M shape, and the heat exchange liquid in the liquid cooling head 803 can use cold water, which is economical and practical and can also achieve the purpose of heat dissipation. The temperature control panel 5 can detect the temperature and humidity of the surrounding air. When the monitored temperature is lower than the set temperature, the TEC semiconductor refrigeration sheet 802 stops refrigeration; when the monitored temperature is higher than the set temperature, the TEC semiconductor refrigeration sheet 802 starts refrigeration, and the heat-conducting block 801 rapidly cools the electric appliance assembly 3, and the absorbed heat is dissipated to the air.
