Description
Technical field
The utility model relates to power battery technology field, especially a kind of power battery pack liquid cooling plate.
Background technique
The lithium ion battery used described in electric car, various aspects of performance are influenced by temperature more significant.Electronic vapour
When vehicle is run under different operating conditions, lithium battery is discharged with different multiplying, and the heat in battery pack also starts to gather, battery temperature
Spending height will cause battery thermal runaway, it usually needs is equipped with liquid cooling plate and is cooled down.
For the battery pack using liquid cooling mode, the heat that battery generates reaches liquid surface by liquid cooling plate, into
And battery pack is taken away by liquid circulation.Liquid cooling plate commonly used by current driving force battery pack is the inflation liquid cooling with " isolated island "
Plate, exchange capability of heat is general, also there is biggish room for promotion.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of power battery pack liquid cooling plate, real
The high efficient heat exchanging of battery modules and liquid cooling plate in existing power battery pack.
To achieve the above object, the utility model uses following technical scheme:
A kind of power battery pack liquid cooling plate, comprising: main board, the main board are hollow structure, the inside of main board
It is laid with feed liquor runner and out liquid stream road side by side, the feed liquor runner is connected to the same end in liquid stream road out and is in U-shape, the feed liquor
The other end of runner is connected to the liquid inlet joint that body board surface is arranged, and the other end in the liquid stream road out is set with body board surface
The liquid outlet connector connection set；Diamond shape array of fins, the diamond shape fin battle array are laid in the feed liquor runner and out liquid stream road
Every two diamond shape fin is one group in arranging, with two diamond shape fins zhou duicheng tuxing and the two diamond shape fins composition each other of group
"eight" shape structure；The big opening end of every group of two diamond shape fins in the feed liquor runner towards liquid inlet joint,
The small open end of every group of two diamond shape fins in the liquid stream road out is towards liquid outlet connector.
Preferably, the main board uses aluminium.
Preferably, the liquid inlet joint and liquid outlet connector are male contact.
Preferably, the liquid inlet joint and liquid outlet connector are perpendicularly fixed at body board surface.
The beneficial effects of the utility model are as follows: the liquid cooling plate of the utility model design, in the stream for laying U-shaped in main board
Road or chute, uniformly distributed diamond shape array of fins in runner, every two diamond shape fin is one group in diamond shape array of fins, is arranged in specific
"eight" shape structure, the arragement direction of each group diamond shape fin is depending on the position of liquid inlet joint and liquid outlet connector, Ke Yi great
Width enhances liquid phase turbulent flow, while increasing the contact area of coolant liquid and liquid cooling plate, to achieve the purpose that enhanced heat exchange.
The overall construction design of the utility model is reasonable, simple reliable, and processing convenience ensure that battery modules and liquid cooling plate
Between heat transfer effect.
