Specific embodiment
Above scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating
The application and be not limited to limitation scope of the present application.Implementation condition used in the examples can be done according to the condition of specific producer
Further adjustment, the implementation condition being not specified is usually the condition in routine experiment.
Embodiment one:
Figures 1 and 2 show that a specific embodiment of this semi-buried liquid cooling battery case of the application, with traditional liquid cooling electricity
Pond case is identical to be, also includes that open cabinet 1, the case lid for closing the opening of the cabinet (are not drawn in figure
Out), the heat exchanging water pipe 2 cooperated with cabinet 1.Cabinet 1 is including cabinet bottom wall 101 and encloses the case-side set on cabinet bottom wall surrounding
Wall 102.When practical application, battery is arranged in the battery case, the cooling water of circulation is passed through into heat exchanging water pipe 2, cooling water is flowing
The heat of battery in cabinet 1 and case is absorbed in dynamic process and battery is made to cool down, then is flowed out from water pipe water outlet.
The key improvements of the present embodiment are that above-mentioned heat exchanging water pipe 2 is thickness of its radial dimension along cabinet bottom wall 101
The flat tube configuration that direction is crushed, heat exchanging water pipe 2 is embedded in cabinet bottom wall 101 and its bottom outer surface exposes cabinet bottom wall
101 and concordant with the bottom outer surface of cabinet bottom wall 101.
It can be appreciated that heat exchanging water pipe 2 is vertically flattened along the thickness direction of cabinet bottom wall, be conducive to cabinet bottom wall
Thickness is done thinner, while the water-flowing amount for being also unlikely to heat exchanging water pipe 2 is very few, and guarantees that heat exchanging water pipe 2 and cabinet have foot
Enough big contacts area.
Heat exchanging water pipe 2 is embedded to 101 bottom of cabinet bottom wall and is exposed, and makes the cabinet bottom wall of 2 top of heat exchanging water pipe
101 parts are solid, and cabinet bottom wall 101 has the bigger thickness above heat exchanging water pipe 2, relative to traditional electricity
Heat exchanging water pipe is fully embedded inside cabinet bottom wall, leads to cabinet bottom wall intermediate hollow for pond case and the solid structure in two sides, for
The cabinet bottom wall of condition of equivalent thickness, the structural strength of cabinet bottom wall 101 is higher (its solid section is more concentrated) in the present embodiment.
It is fixed in cabinet bottom wall 101 moreover, heat exchanging water pipe 2 pours, it is very high with the binding force of cabinet bottom wall 101, compared with
Big improves the structural strength of cabinet bottom wall 101.
In addition, the bottom outer surface of heat exchanging water pipe 2 exposes cabinet bottom wall 101, so that the bottom outer surface of heat exchanging water pipe 2 is straight
Heat dissipation equipment is inhaled in contact, rapidly to draw the cell heat that heat exchanging water pipe 2 absorbs outward.
The bottom outer surface of heat exchanging water pipe 2 and the bottom outer surface flush arrangement of cabinet bottom wall 101, when battery case is located at
When on carrying platform, carrying platform will not exchange hot-water line 2 and apply extruding force and heat exchanging water pipe be caused to deform.
Identical as the combination of traditional heat exchanging water pipe 2 and cabinet 1, above-mentioned heat exchanging water pipe 2 is also that case is fixed in casting
In body bottom wall 101.In production, heat exchanging water pipe 2 is first pressed into flat tube, then flat tube is placed on to the bottom of casting mould die cavity
Portion position, then molten metal (usually aluminum water) is poured into die cavity, its bottom, which is just formd, after cooling is embedded with heat exchanging water pipe 2
Cabinet bottom wall 101.
Above-mentioned heat exchanging water pipe 2 generally uses copper pipe resistant to high temperature or steel pipe.And the present embodiment uses outer layer for compo pipe and
Internal layer is the multiple tube of aluminum pipe.
And in order to which the area for allowing heat exchanging water pipe 2 to expose cabinet bottom wall 101 is big as far as possible, while in order to reduce heat exchange as far as possible
The vertical dimension of water pipe 2, the thickness to promote 101 top half of cabinet bottom wall, the present embodiment is by the bottom outer of heat exchanging water pipe 2
Face 201 is arranged to plane.After completing, the plane of 2 bottom of heat exchanging water pipe integrally it is exposed outside cabinet bottom wall, and and cabinet
The bottom outer surface of bottom wall is concordant.
The outer surface of the cabinet bottom wall 101 is provided with latticed reinforcing rib 101a.
It should be noted that above-mentioned heat exchanging water pipe 2 also can be set at wall box 102, and make 2 surface of heat exchanging water pipe
Expose and flush in the outer surface of wall box 102.
Embodiment two:
Fig. 3 shows another specific embodiment of this semi-buried liquid cooling battery case of the application, this liquid of the present embodiment
The structure of cold battery case and liquid cooling battery case in above-described embodiment one is essentially identical, and the main distinction is, cabinet in the present embodiment
The outer surface of bottom wall 101 is provided with latticed reinforcing rib 101a, and the bottom outer surface of cabinet bottom wall 101 is then formed in these nets
On trellis reinforcing rib 101a.That is to say, being, heat exchanging water pipe 2 is arranged at latticed reinforcing rib 101a, and heat exchanging water pipe 2 and net
The bottom surface of trellis reinforcing rib 101a is concordant.
Above-mentioned reinforcing rib 101a and cabinet bottom wall 101 are structure as a whole, and the two can be integrally cast, can also be when flat
After the cabinet bottom wall of plate completes, then reinforcing rib 101a is formed to the outer surface groove milling of cabinet bottom wall.
Reinforcing rib 101a can further promote the structural strength of cabinet bottom wall 101.
Above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to allow people that can understand this Shen
Content please is simultaneously implemented accordingly, and the protection scope of the application can not be limited with this.It is all according to the application main technical schemes
