Further, described heat conduction shell and cooling water pipe are made by the material of good heat conductivity such as copper or aluminium, and these materials have good heat-conducting, are conducive to strengthen heat-transfer effect.
The course of work of the present invention:
After the liquid-inlet pipeline enters battery case, be evenly distributed in the cooling water pipe in each battery module; The heat that produces when battery operated passes to cooling water pipe through housing, is taken out of by flowing liquid in the cooling water pipe then; After the liquid that cooling water pipe in each battery module flows out gathers, flow out battery case through the liquid outlet pipeline.Share a cooling water pipe between adjacent battery modules, can effectively save the space.In addition, when ambient temperature is lower, when battery need heat, feed the liquid after heating in the cooling water pipe, battery can be heated to working temperature.
The present invention has following technique effect:
1, owing to adopt cooling water pipe as the cooling-part of battery, simple in structure, be easy to make, easy to utilize;
2, share a liquid cooling tube in the battery case between adjacent battery modules, reduced the volume of battery case, be convenient to arrange in the car;
3, cooling water pipe good airproof performance can prevent effectively that the cooling fluid leakage from causing damage to battery;
4, owing to fit mutually between heat conduction shell and the battery outer wall and between the conduit in cooling water pipe and the heat conduction shell, increased area of dissipation, strengthened radiating effect, also can make internal temperature of battery even simultaneously; Temperature and flow by the control cooling fluid can maintain battery temperature the best effort scope;
5, battery thermal management apparatus module design not only is suitable for compact Layout but also can improves the anti-seismic performance of battery case, so be more suitable in electric vehicle.
