Parallel battery module water cooling device suitable for aluminum frame box body

Abstract

The invention discloses a parallel battery module water-cooling device suitable for an aluminum frame box body. The parallel battery module water-cooling device comprises a plurality of water-coolingplates which are flatly laid at the bottom of a battery module, wherein a water channel is arranged in each water-cooling plate, and a cooling liquid is accommodated in each water channel; a water inlet header pipe which is provided with a first multi-way valve, wherein a plurality of liquid ports of the first multi-way valve are communicated with the water inlet ends of the water channels respectively; and a second multi-way valve which is equipped with a second multi-way valve, wherein a plurality of liquid ports of the second multi-way valve are respectively communicated with the water outlet ends of the plurality of water channels. The parallel battery module water-cooling device has the beneficial effects that the pressure loss among the water cooling plates is basically the same, thecooling capacity on each part of the battery module is basically the same, and the battery module can be cooled in a balanced manner.

Description

technical field [0001] The invention relates to the technical field of battery module cooling. More specifically, the present invention relates to a parallel battery module water cooling device suitable for an aluminum frame box. Background technique [0002] The battery module will generate a lot of heat during use, and with the widespread use of the battery module, the energy density and power density of the battery module continue to increase, and the calorific value of the battery is also increasing, and an efficient heat dissipation structure has become an urgent need . In the prior art, a battery module water-cooling device connected end-to-end in series will also be used. Multiple water-cooled plates for heat exchange are commonly used. The front and rear ends of each water-cooled plate are water inlets and water outlets respectively. Connected end to end, because the total water channel of the series water cooling device is long, the pressure loss of the entire wat...

Problems solved by technology

In the prior art, a battery module water-cooling device connected end-to-end in series will also be used. Multiple water-cooled plates for heat exchange are commonly used. The front and rear ends of each water-cooled plate are water inlets and water outlets respectively. Connected end to end, because the total water channel of the series water cooling device is long, the pressure loss of the entire water cooling system is relatively large, and with the cooling liquid flow direction of the water cooling system, the smaller the cooling liquid flow rate and flow rate, the worse the cooling performance, resulting in each battery module. cooling imbalance
