Abstract

Heat dissipation battery casing provided by the utility model, including body, body is made up of the upper lid of casing and casing top, and upper lid is connected with casing, and box house is provided with battery modules, it is characterized in that, upper tops have waveform projection, and the waveform projection is hollow structure, wherein, between hollow structure, battery modules and upper lid, battery modules and casing and adjacent battery modules inside waveform projection, Heat Conduction Material is separately filled with.The waveform projection that the utility model passes through the inner hollow of upper tops, increase the area of dissipation of battery case, and by filling heat-conducting silica gel sheet, heat caused by battery modules can be delivered to by heat-conducting silica gel sheet on Battery case and upper lid, after be delivered to outside battery case, substantially improve the radiating effect of battery case.

Description

Heat dissipation battery casing
Technical field
Electric vehicle engineering field is the utility model is related to, especially belongs to a kind of heat dissipation battery suitable for electric automobile Casing.
Background technology
With expanding economy, fossil energy faces exhaustion, and the problem of environmental pollution thus brought is also more and more serious, respectively The problem of state is to the energy and environment is also increasingly paid attention to.In order to solve energy crisis and environmental pollution, the height of new energy industry Development has globalized, especially extensive use of the electrokinetic cell in terms of automobile.In recent years, with science and technology continuous development and enter Step, the prominent achievement that the development of electric automobile also achieves.
At present, electric automobile uses lithium ion battery mostly.When lithium ion battery works, its own can be produced largely Heat, if these heats effectively can not be delivered to outside battery case, the temperature inside battery case will be raised constantly.When When temperature inside battery case is too high, the performance of battery can be reduced, and its service life can be shortened, or even is also possible to meeting Trigger the spontaneous combustion or on fire of battery, therefore the radiating of battery case is just particularly important.Currently used radiating mode is air-cooled It is cold with liquid, but these types of cooling are needed using fan, water-cooling circulating system etc., not only complex designing, and cost is very high.
The content of the invention
The purpose of this utility model is to provide a kind of heat dissipation battery casing, to reach the radiating for being effectively improved battery case Problem, so as to improve the purpose of battery performance.
Heat dissipation battery casing provided by the utility model, including body, body is by casing and the upper lid of casing top Form, upper lid is connected with casing, and box house is provided with battery modules, it is characterised in that there is upper tops waveform to dash forward Rising, the waveform projection is hollow structure, wherein, hollow structure, battery modules and upper lid, electricity inside waveform projection Between pond module and casing and adjacent battery modules, Heat Conduction Material is separately filled with.
Further, described upper lid forms retractable connection by bolt and casing.
Further, described Heat Conduction Material is heat-conducting silica gel sheet.
Heat dissipation battery casing provided by the utility model, structure design is simple, reasonable, and production cost is low, easy for installation And it is easy to spread, by the waveform projection of the inner hollow of upper tops, the area of dissipation of battery case is increased, and by filling out Heat-conducting silica gel sheet is filled, heat caused by battery modules can be delivered to by heat-conducting silica gel sheet on Battery case and upper lid, rear to pass It is delivered to outside battery case.Because heat-conducting silica gel sheet thermal conductivity factor is significantly larger than the thermal conductivity factor of air, accordingly, with respect to traditional Battery case, the utility model substantially improve the radiating effect of battery case.In summary, the utility model enhances battery case Radiating effect, there is good effect that is practical reliable, improving battery performance.
Brief description of the drawings
Accompanying drawing part discloses the utility model specific embodiment, wherein
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is the close-up schematic view at A in the utility model Fig. 2.
In figure:Covered on 1.;2. casing;3. battery modules;4. Heat Conduction Material;5. waveform projection.
Embodiment
As Figure 1-3, heat dissipation battery casing provided by the utility model, including body, body is by casing 2 and case Upper lid 1 at the top of body is formed, and upper lid 1, by bolt, forms retractable connection with casing 2.Battery mould is installed inside casing 2 Group 3, wherein, the upper top of lid 2 has waveform projection 5, and the waveform projection 5 is hollow structure, in addition, the inside of casing 2 is also Filled with Heat Conduction Material 4, Heat Conduction Material 4 selects heat-conducting silica gel sheet, particularly, hollow structure inside waveform projection 5, Between battery modules 3 and upper lid 1, battery modules 3 and casing 2 and adjacent battery modules 3, heat conductive silica gel is separately filled with Piece.
