Description
Technical field
The utility model relates to a kind of power battery pack liquid cooling plates to support with liner.
Background technique
For new energy battery modules, temperature environment variation has very greatly the reliability of battery core, service life and performance
It influences, therefore, so that temperature is maintained certain range intervals and is seemed and be even more important.Liquid cooling is many electronic riding at present
The preferred embodiment of vehicle in structure, conducts heat by heat conductive silica gel between battery pack and liquid cooling plate, but due to heat conductive silica gel bullet
Property it is poor, after long-time service have thickness loss, lead to liquid cooling plate and battery pack insufficient contact, influence heat-conducting effect；Therefore, existing
Solution be that spring, neoprene or polypropylene foam material are set below liquid cooling plate, but since gap is smaller by (ten
Several millimeters of gaps), spring installing is more difficult, and neoprene or polypropylene foam material, and it is easy to aging after long-time service, up to not
To the service life requirement of automobile related accessory.
Utility model content
The purpose of the utility model is to provide a kind of stable structure and the excellent power battery pack liquid cooling plate branch of support performance
Support liner.
To achieve the above object, the technology employed by the present utility model is
A kind of power battery pack liquid cooling plate support liner, including rigidity and fireproof substrate, by being molded or being molded into
Type in upper surface of base plate layer of silica gel and foaming in the silica gel foamed cotton layer of layer of silica gel upper surface.
Further, the inside or lower surface of the substrate have loss of weight groove/opening.
Further, the substrate and the faying face of the layer of silica gel are the first rubbing surface of concaveconvex structure.
A kind of preferred, the substrate is the wavy steel plate of rectangle.
Further, the faying face of the layer of silica gel and the silica gel foamed cotton layer is the second rubbing surface of concaveconvex structure.
The beneficial effect of this programme is: the million second compression bounces and thickness loss of silica gel foamed cotton layer are smaller, have
It lasting elastic force and does not collapse, in addition to can provide permanent resilient support, pliability can also make up the build-up tolerance between each layer；
Rigid substrates can enhance the intensity of liner, and layer of silica gel provides the thickness of buffering and the transition of connection for substrate and silica gel foamed cotton layer
Function is easy to mold various faying faces as needed, so that being firmly combined between each layer；The liner is easy to fill compared to spring
And if the ageing-resistant, long service life compared to neoprene or polypropylene foam material.
Detailed description of the invention
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Fig. 1 is a kind of preferred implementation structural schematic diagram of liner.
Specific embodiment
The utility model is further described below in conjunction with attached drawing:
With reference to a kind of power battery pack liquid cooling plate support liner shown in FIG. 1, including it is rigidity and fireproof substrate 1, logical
The layer of silica gel 2 for being molded or being molded in upper surface of base plate and foaming are crossed in the silica gel foamed cotton layer of 2 upper surface of layer of silica gel
3.Wherein, the optional flame retardant rating of silica gel foamed cotton layer 3 is the silica gel foam of UL94V-0, and million second compression bounces lose <
40%, thickness loss < 2%.The million second compression bounces and thickness loss of silica gel foamed cotton layer are smaller, have lasting bullet
It power and does not collapse, in addition to can provide permanent resilient support, pliability can also make up the build-up tolerance between each layer；Rigid substrates
1 can enhance the intensity of liner, improve the tear resistance energy of liner, and to be that substrate 1 is provided with silica gel foamed cotton layer 3 slow for layer of silica gel 2
The thickness of punching and the fade function of connection, i.e., when impact force is larger, because there is the buffering of layer of silica gel 2, battery pack support plate will not be squeezed
Press soft silica gel foamed cotton layer 3 and directly arriving to substrate 1 causes to damage, and layer of silica gel 2 is easy to mold various knots as needed
Conjunction face, for being combined respectively with substrate 1 or silica gel foamed cotton layer 3, so that being firmly combined between each layer；The liner is easy to compared to spring
Installing, and the ageing-resistant, long service life compared to neoprene or polypropylene foam material.
As a kind of preferred structure of substrate 1, the inside or lower surface of the substrate 1 have loss of weight groove/opening, can protect
Mitigate 1 weight of substrate in the case where demonstrate,proving thickness, while 3 thickness of layer of silica gel 2 and silica gel foamed cotton layer can be reduced, reduce liner at
This.The groove/opening of substrate 1 can be hollow hole or honeycomb hole or C-channel etc., such as hollow plate, cellular board, C slot aluminum profile
Deng.
As another preferred structure of substrate 1, the faying face of the substrate 1 and the layer of silica gel 2 is concaveconvex structure
The shearing resistance between substrate 1 and layer of silica gel 2 can be improved in first rubbing surface, the first rubbing surface.Such as waveform, zigzag, shrinkage pool
Shape, irregular rough surface etc..
Further, the substrate 1 is the wavy steel plate of rectangle.The wavy substrate of rectangle, the empty avoiding of the existing loss of weight in downside, on
There are the male and fomale(M&F) of enhancing shearing resistance, and the rectangle male and fomale(M&F) of upside in side again so that layer of silica gel is embedded above substrate, make substrate with
Shearing resistance between layer of silica gel maximizes.
As a kind of preferred structure of layer of silica gel 2, the faying face of the layer of silica gel 2 and the silica gel foamed cotton layer 3 is bumps
Second rubbing surface of structure, more specifically, the second rubbing surface can be serrated face.Second rubbing surface improves layer of silica gel 2 and silica gel
Shearing resistance between foamed cotton layer 3.
The above is not limit the technical scope of the present invention, all according to the utility model technical spirit
To any modification, equivalent variations and modification made by above embodiment, the model of the technical solution of the utility model is still fallen within
In enclosing.
