[0016] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be further described in detail. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0017] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a double-sided heat dissipation water-cooled plate, including aluminum plate 10, the inside of aluminum plate 10 is embedded with several equidistant distribution heating element 20, and the inside of aluminum plate 10 is opened with groove 101, and copper pipe 30 is fixedly installed in the inside of groove 101, heating element 20 is distributed on the upper and lower surfaces of aluminum plate 10, and heating element 20 is distributed in axial symmetry, and copper pipe 30 is located in the inside of heating element 20.

[0018] In the embodiment, the heating element 20 is embedded on the aluminum plate 10, and the groove 101 is formed in the aluminum plate 10, and the copper pipe 30 is welded in the groove 101, so that the copper pipe 30 can contact the heating element 20 on both sides, so that the copper pipe 30 is closer to the heating element 20 and is more conducive to heat dissipation. In the heat dissipation process, the cooling liquid circulates in the flow channel formed in the aluminum plate 10, thereby taking away heat. When the object to be cooled is in close contact with the aluminum plate 10, heat is transferred from the object to the aluminum plate 10, and then the heat is transferred to the cooling liquid in the copper pipe 30 through the conduction of the aluminum plate 10. The cooling liquid absorbs heat and the temperature rises. In the heat exchanger and other heat dissipation equipment, the heat is released to the external environment, thereby realizing the transfer and dissipation of heat. The overall device can simultaneously perform heat exchange in the upward and downward directions, thereby increasing the contact area of the cooling liquid with the heat dissipation surface by one time, and heat can be taken away from the heat source more quickly. The heat dissipation efficiency is better than that of the single-sided water-cooled plate.

[0019] Specifically, the connection mode between the aluminum plate 10 and the copper pipe 30 is soldering with tin paste, and the copper pipe 30 is in a tubular shape by stamping.

[0020] Specifically, the aluminum plate 10 is formed by stamping in an organic processing mode.

[0021] Specifically, the outer diameter of the copper pipe 30 is 7-12.7 mm, the copper pipe 30 is in a U-shaped type, the groove 101 is in a U-shaped type, the copper pipe 30 and the groove 101 are positionally corresponding and adapted, and the copper pipe 30 is welded in the groove 101 by brazing.

[0022] Specifically, the cooling liquid filled in the copper pipe 30 includes but is not limited to propylene glycol.

[0023] In the embodiment, the double-sided water-cooled plate has high heat dissipation efficiency, and in the case of meeting the same heat dissipation requirement, the volume and mass thereof can be smaller. For some devices with strict requirements on space and weight, such as electronic devices in the fields of new energy vehicles, aerospace, etc., the double-sided water-cooled plate can more effectively utilize the limited space and reduce the overall weight of the device. Meanwhile, the double-sided water-cooled plate can also help to improve the power density of the device and has higher reliability. The soldering connection technology of the double-sided water-cooled plate reduces the intermediate heat conduction interface and connection links, reduces the probability of heat dissipation failure and faults caused by interface thermal resistance, connection looseness, etc. Moreover, the structure of the double-sided water-cooled plate is relatively more stable and can withstand greater thermal stress and mechanical stress, thereby having better reliability and durability in the long-term use process and having better temperature uniformity. Furthermore, the double-sided water-cooled plate can uniformly cool both sides of the heat source and avoid the uneven heating phenomenon that may occur in the single-sided water-cooled plate.

[0024] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit them.
