According to the liquid cooling heat dissipation type tray, (1) liquid cooling pipes are adopted for heat dissipation, compared with the liquid cooling heat dissipation through the inner part of the tray body, the structural strength of the tray body is not reduced, and the service life of the tray is prolonged; (2) the heat conducting plate is used as a heat conducting bridge between the liquid cooling pipe and the battery, so that the liquid cooling pipe is not in direct contact with the battery, and the harm of liquid leakage of the liquid cooling pipe to the battery is avoided; (3) the heat conducting plate is in contact with the battery, so that the contact area is larger, the heat dissipation is more uniform, and the problem of local overheating caused by uneven heat dissipation is avoided compared with the direct contact of the liquid cooling pipe and the battery.
When in heat dissipation, the heat conducting plate 2 absorbs heat generated by the battery, cooling liquid flows in the liquid cooling pipe 3, and the cooling liquid 3 exchanges heat with the heat conducting plate 2 to take away the heat on the heat conducting plate 2; the heat conducting plate 2 can be made of a copper plate or an aluminum plate, has good heat conducting performance, but has slightly insufficient strength; the heat conducting plate 2 can also adopt an aluminum alloy plate, and the heat conducting performance is slightly lower than that of a copper plate or an aluminum plate, but the strength is higher; on the premise of meeting the heat conduction performance, the heat conduction plate 2 is preferably made of an aluminum alloy plate; in addition, the heat conducting plate 2 can also be a silica gel plate, has excellent heat conducting performance, can be used as a bottom pad of a battery due to good flexibility, reduces vibration and bottom collision of the battery in the running process of the automobile, and plays a role in protecting the battery. The liquid cooling pipe 3 adopts a coiled pipe, so that the contact area is ensured.
As an improvement of the technical scheme, the lower surface of the heat conducting plate 2 is attached to the bottom of the accommodating groove 11; the liquid cooling pipe 3 is partially embedded on the bottom of the accommodating groove 11, and the other part is embedded on the heat conducting plate 2.
The liquid cooling pipe 3 is embedded between the heat conducting plate 2 and the bottom of the accommodating groove 11, so that the liquid cooling pipe 3 does not bear the weight of the battery and the heat conducting plate 2, deformation of the liquid cooling pipe 3 due to overlarge stress is avoided, meanwhile, the contact area between the liquid cooling pipe 3 and the heat conducting plate 2 is increased due to the embedded design, and the heat dissipation efficiency is improved; of course, how the liquid cooling tube 3 is embedded specifically is set according to the thickness of the heat conducting plate 2 and the thickness of the bottom of the accommodating groove 11, and the liquid cooling tube can be half embedded into the heat conducting plate 2, half embedded into the bottom of the accommodating groove 11, or the liquid cooling tube can be mostly embedded into the heat conducting plate 2, and the rest embedded into the bottom of the accommodating groove 11, and is set according to specific use conditions. The liquid inlet end and the liquid outlet end of the liquid cooling pipe 3 are uniformly distributed on the side wall of the tray body 1.

Because copper and aluminum plates have lower strength, when the aluminum plates are used as the heat-conducting plate 2, the aluminum plates are not suitable for being provided with a heat dissipation cavity 21 for air cooling, and the silica gel plates are the same.
As an improvement of the above technical solution, a plurality of support columns 211 are arranged in the heat dissipation cavity 21; the support column 211 is integrally provided between the top and bottom surfaces of the heat dissipation chamber 21.
The support columns 211 are arranged in the heat dissipation cavity 21, so that the structural strength of the heat dissipation plate 2 is improved on one hand, and on the other hand, the support columns 211 are connected with the top surface and the bottom surface of the heat dissipation cavity 21 to play a role in heat conduction, so that heat on the upper surface of the heat dissipation plate 2 is quickly transferred to the lower surface, and then is taken away through heat exchange of the liquid cooling pipe.
