Embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Set in electric automobile power battery passive cooled device as shown in Figure 1, including Battery case 3, Battery case
There are battery modules 1, the side of Battery case 3 is radiating surface, and the casing radiating surface outer side covers have absorbent material 4, described
Absorbent material 4 is water-absorbing sponge or water absorbing fabric etc..Before electric automobile during traveling, the filling full water in absorbent material 4, electronic
In vehicle traveling process, the moisture evaporation in absorbent material 4 is taken away by the surface heat of Battery case 3, realization pair by natural wind
The cooling of battery modules 1, when car is static, can carry out water-refilling operation, such a structure need not take battery case to absorbent material 4
Space in body 3, without extra fluid dielectric coolant and extras etc., temperature-fall period is without extra power consumption, simple to operate, maintenance side
Just, the temperature of Battery case 3 can be efficiently controlled, greatly extends battery, the structure of Battery case 3 need not be destroyed in addition,
Highest degree of protection IP67 is can reach, greatly ensures battery pack safety and reliability, and need not be on battery case body
Heat emission hole is opened up, casing degree of protection is improved.
On the basis of the above, the outer surface of battery modules 1 contact is provided with thermally conductive sheet 2, and the thermally conductive sheet can be pasted
On battery modules outer surface, the cooling surface contacts of the thermally conductive sheet 2 and Battery case 3, the setting of thermally conductive sheet 2 can rapidly by
Heat transfer in battery modules 1 accelerates the heat transfer efficiency of battery modules 1, realizes battery modules to the radiating surface of Battery case 3
1 rapid cooling.
On the basis of the above, in addition to water tank 5 and feed pipe, described feed pipe one end is connected with water tank 5, and feed pipe is another
End is stretched into inside absorbent material 4, because absorbent material 4 has water suction effect, after water is evaporated in absorbent material 4, water-absorption material
The suction of material 4 can absorb the water in water tank 5 so that electric automobile can also realize automatic water supplement in the process of moving.
Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect
Step is described in detail, be should be understood that and be the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements done etc. all should be wrapped
