Battery liquid cooling structure, simple in structure symmetrical, general purpose accessory is more, is easy to be brazed on a large scale, and connector is less, it is easy to implement it is low at
This.
We use volume ratio for 1:1 glycol water, 25 DEG C of room temperature, pressure difference (note when flow is 7.5L/min：
Entire pack flows are 15L/min, and cooling water pipe is symmetrical, then the water pipe flow of plane of symmetry side is 7.5L/min), do not having
Have in the case of adding flow deflector, emulated using Starccm+, using coupling second order Realizable K-Epsilon two-
Layer all y+ model analysis are about 31kPa from the visible inlet outlet pressure differential of water pipe static pressure Pressure Simulation result.When on tail portion
Increase a flow deflector on the outside of layer inlet tube, maximum pressure can increase 389Pa.Simulation result shows in the emulation boundary condition
Under, increase increase flow deflector on the inside of flow deflector ratio on the outside of inlet tube and is relatively beneficial to flow field.
