[0003] The existing energy storage system lithium battery PACK package mainly has three heat dissipation methods: air natural cooling, forced air cooling and liquid cooling. Natural cooling can no longer effectively dissipate the heat of the battery system. Forced air cooling will cause the temperature difference of the battery system to be too large. At the same time, it also cannot meet the cooling requirements of the battery pack at a large discharge rate. For this reason, this application proposes a new energy lithium battery liquid cooling PACK package. Utility Model Content

[0022] Furthermore, by opening a plurality of heat dissipation holes 311 connected to the interior of the heat exchange plate 31 at the contact end between the heat exchange plate 31 and the bottom end of the PACK package monomer 1, the heat generated during the working process of the PACK package monomer 1 is dissipated to the interior of the heat exchange plate 31 through the heat dissipation holes 311, and a heat exchange process is performed with the coolant filled in the heat exchange bend 32 through the heat exchange bend 32.
