Description

A kind of heat abstractor of batteries of electric automobile module
Technical field
The utility model relates to a kind of heat abstractor of batteries of electric automobile module, particularly a kind of heat abstractor adopting the batteries of electric automobile module of air-cooled and heat pipe heat radiation.
Background technology
Battery is as energy storage device element, it is the critical component of electric automobile, it produces a large amount of heats and causes the cell of battery module inside to occur thermal runaway phenomenon in charge and discharge process, make between each cell, to produce very serious unbalanced Temperature Distribution, thus cause the performance between cell not mate, cause battery module premature failure further.
At present, the electrokinetic cell for electric automobile adopts air blast cooling or liquid cooling to dispel the heat mostly.Heat in power brick is taken away by wind by air blast cooling, and the maximum shortcoming of this mode is the local temperature skewness caused in power brick, and the temperature often near air inlet is low, and the temperature of air outlet is high.The inhomogeneities of this temperature directly can have influence on the consistency of cell in power brick, can accelerate the deterioration of power brick serviceability.Although and the mode radiating effect of liquid cooling is better, because the inside of power brick is made up of many cell connection in series-parallel, can easily cause battery short circuit to damage if the heat pipe of liquid cooling breaks.
In view of present battery modules heat is mainly collected at battery side, these heats can not be taken away by existing radiating mode, cause temperature to rise and the temperature difference is large affects battery and useful life, are necessary to design the more all even effective heat abstractor of a kind of heat radiation.
Summary of the invention
For overcoming the shortcomings and deficiencies of above-mentioned prior art, the utility model provides a kind of heat abstractor adopting air-cooled and heat pipe to carry out the batteries of electric automobile module dispelled the heat.
The utility model adopt technical scheme be: a kind of heat abstractor of batteries of electric automobile module, comprises
Battery modules, heat-transfer device and air cooling equipment,
Battery modules comprises several cells be arranged in parallel;
Heat-transfer device, be arranged at battery modules side, export to outside battery modules for internal battery pack being sent heat, described heat-transfer device comprises fin and heat pipe, fin is closely set in the side of battery modules, heat pipe is vertically installed on fin side, and inserts between cell and cell, and fin another side is distributed with radiating fin;
Air cooling equipment, is arranged at one end of heat-transfer device, takes away the heat on heat-transfer device with high wind, and described air cooling equipment comprises one or more fan, the direction that described fan air-out direction extends along the radiating fin of fin.
Fin on described fin is for be arrangeding in parallel, and fin thickness scope is 1-5mm, and fin pitch is 2-5mm.
Described heat pipe is flat, and thickness range is 3-5mm.
Described heat pipe is arch door shape, and inward at both ends bending.
Described heat pipe is arranged on fin bottom surface by being welded and fixed.
Described heat pipe is arranged on fin bottom surface by interference fit engaging, fin bottom surface has groove that is corresponding and heat pipe thickness.
The material of described fin is aluminium, and described heat resistant material is copper.
Two battery modules heat abstractors adopt the aspectant direction of radiating fin to install when installing.
The beneficial effects of the utility model are: the heat abstractor of a kind of batteries of electric automobile module that this case proposes, utilize the thermal conduction characteristic of heat pipe to be conducted to outside power brick by cell heat to dispel the heat, to reach the object of battery heat radiation, can temperature cell heat is taken away fast reach the object reducing battery temperature between balancing battery, battery performance consistency can be promoted and extend battery.
Accompanying drawing explanation
Fig. 1 is the structural blast figure of the utility model heat abstractor embodiment.
Fig. 2 is the scheme of installation of the utility model two battery modules heat abstractors.
Fig. 3 is the heat pipe structure schematic diagram adopted in the utility model.
Embodiment
Understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the heat abstractor of batteries of electric automobile module that this case provides comprises battery modules, heat-transfer device and air cooling equipment.
Battery modules 1 comprises several cells be arranged in parallel, the cell quantity that each battery modules can be selected as required to comprise and the quantity of required battery modules;
Heat-transfer device, exporting to outside battery modules for internal battery pack being sent heat, comprising fin 3 and heat pipe 2.
Fin 3 is closely set in the side of battery modules 1, and heat pipe 2 is fixedly installed on fin 3 bottom surface, and is affixed between cell and cell.Fin on fin 3 is for be arrangeding in parallel, and fin thickness scope is 1-5mm, and fin pitch is 2-5mm, and the material of fin is aluminium.As shown in Figure 2, the aspectant direction of radiating fin is adopted to install when two battery modules heat abstractors are installed.
As shown in Figure 3, heat pipe 2 is made into flat, door font, full copper production, and bends inwards.Thickness range is 3-5mm.One end is affixed on battery side, one end is combined with fin by welding or close-fitting mode, namely be arranged on fin bottom surface by being welded and fixed, or be arranged on fin bottom surface by interference fit engaging, fin bottom surface has groove 4 that is corresponding and heat pipe thickness.Battery side heat is passed to fin by heat pipe, is taken away the heat on fin by air-flow, to reach the object of battery heat radiation.
Air cooling equipment, can select one or more fan, is arranged on the side of battery modules, the direction that the direction blowing out wind extends along radiating fin, takes away the heat on heat-transfer device with high wind.
