Embodiment Construction

[0061] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] When the battery pack is working, the main heat-generating part is the cell body. At the same time, the tabs and the battery management system will also generate heat. The heat generated by the cell body can be dissipated through the battery case, but it is affected by the structural layout of the battery pack. Limitation, the heat generated by the tabs, the heat conducted by the ...

The invention provides a battery radiator used for being in thermal contact with a pole lug of a battery, at least one ventilation hole is formed in the side face of the battery radiator, the at least one ventilation hole penetrates through the two side faces of the battery radiator, and a plurality of cooling fins are arranged in the at least one ventilation hole. The invention provides a battery radiator and a battery pack, which are used for at least solving the technical problems of low heat dissipation efficiency and poor heat dissipation effect of battery tabs.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to a battery radiator and a battery pack. Background technique [0002] UAVs are more and more commonly used in the fields of transportation, industry and agriculture. When UAVs are operating in the air, the battery continues to discharge, and the battery itself is very hot, especially when the UAV is under high-power conditions. Batteries often have serious heating problems during use. If the heat generated by the battery cannot be dissipated in time, a large amount of heat will accumulate and the battery will heat up. Excessively high battery temperature will reduce the efficiency of the battery, shorten the working life of the battery, and even cause a safety accident in severe cases. [0003] The battery radiator is a device used for battery heat dissipation. Existing battery radiators usually use water-cooling or air-cooling to cool the battery. The water-cooling metho...
