Abstract
The invention provides a temperature control shell for a lithium battery pack. The shell comprises a shell body and a cover plate arranged at the opening of the shell body, the shell body comprises an external layer of the shell body and an internal layer of the shell body, and the external layer and the internal layer are connected with each other, thus forming a cavity. Phase change materials are filled into the cavity to control the temperature. The temperature control shell has good temperature control effect and simple structure.
Description
Technical field
The present invention relates to a kind of temperature control case for lithium battery bag.
Background technology
Along with the progress of development of science and technology and society, people are also more and more higher to the requirement of quality of life.The lithium battery of environment-friendly type has entered in the middle of people's the life as power source, electric tool power supply, automobile starting power supply, the high-energy portable power source of the vehicles, is used the approval with common people widely.Electric vehicle such as electric bus travel on road, the influence that is subjected to ambient temperature is bigger, under the situation of summer high-temperature, temperature is up to 40 ℃, radiation temperature on the asphalt road is also up to more than 55 ℃, electric bus battery in motion is in the heavy-current discharge state always, also can produce a part of heat.Because be subjected to the influence of hot environment, the service efficiency of lithium battery can not get fully playing, its life-span also will have a greatly reduced quality.In order to keep lithium battery in the good environment temperature, to work, in battery case, used cooling system.Present cooling system has water-cooled and air-cooled, the effect of water-cooling system is better by contrast, but because operating voltage height, the electric current of automobile are big, the battery case of water-cooling system must be accomplished anticracking, leakproof and insulation, this just makes that the structure of battery case is complicated, should not process and produce.Effect is relatively poor comparatively speaking to adopt air cooling system, air cooling system depends on the height of temperature, summer temperature even be higher than 35 ℃, and the temperature of battery surface also can rise to more than 35 ℃ rapidly so, same under the situation of low temperature, the temperature of battery surface also descends thereupon.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of temperature control case for lithium battery bag, and is simple in structure, and temperature control is effective.
For solving above-mentioned prior art problems, the present invention adopts following scheme: a kind of temperature control case for lithium battery bag, comprise housing, be located at the cover plate at shell nozzle place, described housing comprises the outer and housing internal layer of housing, and described housing skin and housing internal layer are interconnected to form cavity.
As preferably, be provided with phase-change material layers in the described cavity.Can reach good temperature control effect.
As preferably, described housing internal layer opening part is provided with dividing plate, and described dividing plate is provided with material hole.Utilize material hole to inject covert material.
As preferably, the outside central authorities of described each sidewall of housing internal layer are provided with spacer block, and the thickness of described spacer block is identical with the width of dividing plate.Make housing internal layer and housing skin closely cooperate.
As preferably, the inwall of the outer bottom of described housing is provided with spacer block.
As preferably, described cover plate is provided with the groove of symmetry.Be convenient to the assembling of cover plate.
Beneficial effect:
The present invention adopts technique scheme that a kind of temperature control case for lithium battery bag is provided, and utilizes housing skin and housing internal layer to be interconnected to form cavity, is provided with phase-change material layers and is used for temperature control in cavity, and temperature control is effective, and is simple in structure.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of cover plate of the present invention;
Fig. 3 is the structural representation of middle shell internal layer of the present invention;
Fig. 4 is the outer field structural representation of middle shell of the present invention.
Embodiment
As Fig. 1 to Fig. 4, a kind of temperature control case for lithium battery bag comprises housing 2, is located at the cover plate 1 of housing 2 opening parts, and described housing 2 comprises housing outer 3 and housing internal layer 4, and described housing outer 3 and housing internal layer 4 are interconnected to form cavity.Be provided with phase-change material layers 5 in the described cavity.Described housing internal layer 4 opening parts are provided with dividing plate 6, and described dividing plate 6 is provided with material hole 7.Utilize material hole 7 in cavity, to inject covert material and be used for temperature control.The outside central authorities of described housing internal layer 4 each sidewalls are provided with spacer block 8, and the thickness of described spacer block 8 is identical with the width of dividing plate 6.The inwall of outer 3 bottoms of described housing is provided with spacer block 8.Make housing internal layer 4 and housing skin 3 closely cooperate.Described cover plate 1 is provided with the groove 9 of symmetry.Be convenient to the assembling of cover plate.Cover plate on four limits, base and the housing of battery pack case housing is injection molded into the cavity structure respectively, with screw and fluid sealant its assembling combination is got up again, also can reach identical effect, but the technology relative complex.
The present invention can provide high temperature resistant type and two kinds of shells of low temperature resistant type according to the difference of phase-change material in the phase-change material layers.The shell of high temperature resistant type is that to adopt a kind of critical temperature be that 35 ℃ phase-change material injects in the cavity, when ambient temperature reaches 35 ℃, this phase-change material becomes liquid phase by solid phase, absorbs a large amount of extraneous heats, allows lasting the remaining on below 35 ℃ of battery surface temperature.The shell of low temperature resistant type is that to adopt a kind of critical temperature be that 10 ℃ phase-change material injects in the cavity, and when ambient temperature is lower than 10 ℃, this phase-change material becomes solid phase by liquid phase, discharges a large amount of heats, allows lasting the remaining on more than 10 ℃ of battery surface temperature.The heat of transformation is meant the heat that material absorbs or discharges in the phase change process, mainly contain heat of evaporation, melting heat and the heat of sublimation.Heat of transformation when heat of evaporation is meant and becomes gas phase by liquid phase; Heat of transformation when melting heat is meant and becomes liquid phase by solid phase; The heat of transformation when heat of sublimation is meant and directly becomes gas phase by solid phase.
