Problems solved by technology
[0002] At present, the waterway connection of power battery packs is basically connected in series and parallel through water pipes and quick connectors. This method will take up a lot of space in the battery pack and reduce the overall energy density of the battery pack. There is also a risk of leakage from the water pipe joints.

The invention discloses a power battery pack water cooling channel water chamber structure which comprises a water chamber body, the water chamber body comprises a water inlet gathering channel and awater outlet gathering channel, the two ends of the water inlet gathering channel and the two ends of the water outlet gathering channel share one water chamber blocking cover for blocking, and a water inlet and a water outlet are oppositely arranged. The cross section area of the water inlet converging channel is smaller than that of the water outlet converging channel, a connecting claw is integrally formed on the outer wall of the water inlet converging channel, and the water chamber body is fixedly installed on a battery pack water cooling plate through the connecting claw. The structure saves a water pipe and a quick connector, increases the internal space of the battery pack, increases the arrangement of battery capacity, and improves the energy density of the battery pack. The waterchamber is simple in structure, the water channel section is greatly reduced, the filling amount of cooling liquid of the whole cooling system is reduced, and the mold opening cost is low. The structure can adapt to water-cooling plates with different structures.
Description
Technical field: [0001] The invention belongs to the technical field of automobiles, and in particular relates to a water chamber structure of a power battery pack water cooling channel. Background technique: [0002] At present, the waterway connection of power battery packs is basically connected in series and parallel through water pipes and quick connectors. This method will take up a lot of space in the battery pack and reduce the overall energy density of the battery pack. There is also a risk of leakage from the water pipe joints. Invention content: [0003] The technical problems to be solved by the present invention are: omit water pipes and quick connectors, increase the internal space of the battery pack, increase the arrangement of battery power, and increase the energy density of the battery pack. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a power battery pack water cool...
