Layer, is acted on by fan, the gas circulation of air heat-insulation layer is blowed to housing, carries out whole heat exchanges by housing with the external world,
Efficiently solve foregoing problems.
This utility model is achieved through the following technical solutions：
A kind of variable TR battery case, includes upper shell and lower house, is provided with battery core, between housing and battery core in housing
If air heat-insulation layer, in housing, it is provided with the fan driving air flow in air heat-insulation layer, fans drive air flows through battery core table
Face and inner walls, constitute the circulation canal of battery core and housing heat exchange, and the heat that inner walls absorb outwards is distributed by housing.
Preferably, described air heat-insulation layer directly contact inner walls.
Further, upper shell and lower house are to be tightly connected.
Further, battery core and air heat insulation interlayer are provided with thermal insulation board.
Preferably, described battery core surface is provided with the fin strengthening radiating.
Preferably, described inner walls are provided with the fin strengthening radiating.
It should be appreciated that aforementioned description substantially and subsequently detailed description are exemplary illustration and explanation, should not
As the restriction to the claimed content of this utility model.
The beneficial effects of the utility model are：
1st, this utility model sets air heat-insulation layer between housing and battery core, is acted on by fan, by the gas of air heat-insulation layer
Body circulation blows to battery core surface and housing, carry out whole heat exchanges by housing and the external world, it is to avoid valuable using refrigerator etc.
Part, has saved cost.
2nd, this utility model upper shell and lower house are tightly connected so that casing forms confined space, therefore sealing property
Well.
