Specific embodiment
The specific embodiment of electric automobile power battery liquid cooling plate of the present invention is provided below in conjunction with attached drawing.But it should refer to
Go out, implementation of the invention is not limited to following embodiment.
Referring to Fig. 1 and 3.A kind of electric automobile power battery liquid cooling plate contains extruding flat tube 1, hole 101, the first header
2nd, waist type groove 201, the second header 3, inlet 4, the first liquid outlet 5, the second liquid outlet 6, partition 7, blanking cover 8 and soaking plate 9.
The extruding flat tube 1 is disposed in parallel relation to one another by multiple flat tube configurations to be formed, and the flatness for squeezing 1 surface of flat tube should be less than 0.5mm.
At the both ends for squeezing flat tube 1, the first header 2 and the second header 3 are set respectively：In first header 2 and second
Waist type groove 201 is set on header 3（Referring to Fig. 7）；The waist type groove 201 can be used the mode of machining or punch process into
Type.2 and second header 3 of the first header is inserted into the both ends for squeezing flat tube 1 by the waist type groove 201 respectively
Interior, insertion depth can improve soldering qualification rate between 3~5mm.
As shown in Figure 4,5, the width TW for squeezing flat tube 1 is 30mm~70mm, thickness in the section for squeezing flat tube 1
TH is 4mm~6mm, and the quantity of internal holes 101 is 5~16（Referring to Fig. 6）, squeeze flat tube 1 between interval S for 6mm~
11mm (as shown in Figure 5) certainly, is to be not limited to these sizes in implementing, needs specifically to be set according to pressure drop and temperature difference requirement
Meter.
Partition 7 is set in the inside of 2 and second header 3 of the first header, in first header 2 and described
The both ends of second header 3 set blanking cover 8 respectively.Inlet 4 is set on first header 2 again, and the inlet 4 is set
It puts in 2 position in the middle of the first header；Go out liquid equipped with the first liquid outlet 5 and second on second header 3
Mouth 6；First liquid outlet, 5 and second liquid outlet 6 is separately positioned on the both ends of second header 3.The inlet 4,
First liquid outlet 5 and the second liquid outlet 6 are all bent towards the one side of setting soaking plate 9 in 90 degree.
Liquid flows into power battery liquid cooling plate by inlet 4, two plume hydrodynamics is divided under the blocking of partition 7, by three
A flow flows out from 5 and second liquid outlet 6 of the first liquid outlet, then comes together in exterior line respectively.This one into two
Go out, symmetrical flow scheme design, be conducive to improve the uniformity for squeezing the distribution of 1 internal flow of flat tube, it is entire so as to be promoted
The uniformity of liquid cooling plate surface temperature improves heat transfer efficiency, can further reduce the maximum temperature of power battery.Certainly, to make
The heat transfer efficiency higher of liquid cooling plate, liquid cooling plate surface temperature uniformity is more preferable, and aforesaid way is without being limited thereto, but can be according to reality
Border situation is adjusted.
In one soaking plate 9 of front setting for squeezing flat tube 1, the flatness of the soaking plate 9 should be less than 0.5mm, with

Surface.The reverse side for squeezing flat tube 1 is exactly then the plane for squeezing flat tube 1（Referring to Fig. 2）.The soaking plate 9 and the extruding
It is connected as a single entity between flat tube 1 using brazing mode.
It squeezes the clear area among flat tube 1 and is limited to soldering or Sheet Metal Forming Technology and specific appearance and size and selected extruding flat tube
The limitation of size, therefore, the spacing between general multiple flat tube configurations are 6mm~11mm, and clear area area accounts for liquid cooling plate unilateral side
The ratio of the gross area is 8% to 22%, this can cause very big waste.And the design of soaking plate 9 not only increases heat exchange area, and
And the lateral heat transfer squeezed between flat tube 1 is enhanced, and the deficiency of clear area heat exchange can be effectively made up, it is whole so as to promote power battery
The heat exchange efficiency of body improves the uniformity of liquid cooling plate surface temperature.
In implementation, the extruding flat tube 1, the first header 2, the second header 3, partition 7, blanking cover 8, soaking plate 9 should be equal
Using aluminum alloy junction component, heat exchange can be effectively performed.NB soldering processes can be used in each structural member, once by battery fluid
The integral braze-welded molding of cold plate.The appearance and size of the battery liquid cooling plate of the present invention should be determined according to the size of battery module, can be adopted
With square configuration, but it is not limited to square configuration.
The above is only the preferred embodiments of the invention.It should be pointed out that the ordinary skill people for the art
For member, without departing from the principle of the present invention, it can also make several possible variations and modification or be revised as equivalent change
The equivalent embodiment of change, these should all belong to the range of technical solution of the present invention protection.
