Abstract
A method for arranging the battery in the cooling mechanism for electric vehicle is characterized by that in X direction, adjacent cells are a battery, the ends of two cells in same battery are closely contacted, and the batteries are arranged at intervals; in Y direction, adjacent cells are a battery, the sides of two cells in same battery are closely contacted, and the batteries are arranged at intervals; and in Z direction, the layers are arranged at intervals and batteries are staggered. Its advantages are large heat dissipating area and high heat dissipation effect.
Description
Technical field
The present invention relates to the arrangement that evenly cooling is installed in a plurality of batteries on the elec. vehicle, belong to the elec. vehicle heat management system
Technical field.
Background technology
Along with the fast development of electronlmobil, the progress of battery technology, the power of battery pack is increasing, and it is more and more littler to take volume, and corresponding cal val also increases, and how high efficiency and heat radiation keeps the normal working temperature of battery to seem day by day urgent.Battery pack in the existing electric motor vehicle cell box all is regularly arranged, as shown in Figure 1, 2.When they are arranged in the battery case uniformly, the from outside cooling-air flow that enters is with the slit of passing between the battery unblockedly, because air-flow even can straightaway, the turbulization vortex is difficult for being disturbed, less with the effective area of contact of battery surface, convective heat exchange is less, so cooling effectiveness is not high.
Summary of the invention
The purpose of this invention is to provide the high battery pack arrangement mode of a kind of radiating efficiency.
Battery pack arrangement of the present invention is referring to accompanying drawing.On the directions X, the battery of sustained height layer is one group with adjacent Unit two, and perhaps two batteries of close wall belong to two battery end closed contacts of one group together separately as one group, and two adjacent groups keeps certain intervals to be arranged in order with ventilating air; On the Y direction, the battery of sustained height layer is one group with adjacent Unit two also, and perhaps two batteries of close wall are separately as one group, and paste mutually two battery sides that belong to a group together, and two adjacent groups keeps certain intervals to be arranged in order; On the Z direction, adjacent two layers keeps certain intervals, and the layout of battery pack staggers, and promptly wherein one deck is all aimed at position, space between the adjacent layer battery pack to every Battery pack contact jaw on directions X still is the Y direction.
Increase battery efficiently radiates heat area, improve the battery surface convection transfer rate, reduce thermal resistance by the employing mode of arranging battery that is staggered, improve radiating effect.Particularly, improve the battery surface cooling-air flow and flow, improved battery pack heat-dissipation homogeneity by staggered cooling-air flow guide functions.
Description of drawings
Fig. 1 is a battery pack arranged schematic perspective view commonly used at present
Fig. 2 is a battery pack arranged lateral plan commonly used at present
Fig. 3 is the present invention's battery pack schematic perspective view that is staggered
Fig. 4 is the present invention's battery pack side view (arrow represent air-flow trend) that is staggered
Fig. 5 is the present invention's battery pack front elevation (arrow represent air-flow trend) that is staggered
The specific embodiment
Battery arrangement mode of the present invention is shown in Figure 4 and 5.See that in lateral plan 4 No. 2 and No. 3 battery closed contacts make most of air-flow to pass through between No. 1, No. 2 batteries and the space between No. 3, No. 4 batteries, seldom a part of air-flow passes from the slit between No. 1, No. 4 and wall.After air-flow arrives second layer battery (No. 5, No. 6, No. 7, No. 8), because between No. 5, No. 6 batteries and the closed contact between No. 7, No. 8 batteries, be forced to change and flow to, between No. 6, No. 7 batteries and flow to last layer with the space of wall No. 5, No. 8.Make the space dislocation like this between adjacent levels, except that leaning on some batteries of wall, all paired closed contact hinders air-flow and directly passes.So on the gas channel of complications, constantly grow little whirlpool, increased the area of contact and the convective heat exchange effect of cooling-air flow and battery surface greatly at each turning separation point.The situation of front elevation 5 is similar to Fig. 4, no longer repeats.
Two vents are located at battery case bottom and top opposite face, and air is sent or drawn to cooling fan towards one of them vent.
With common batteries group arrangement mode with compare by design-calculated staggered pattern of the present invention after can see: after the staggered battery pack, because the but air communication space dislocation of crossing of cooling between every layer of battery, battery efficiently radiates heat area increases, and the battery surface convection transfer rate increases, thermal resistance reduces; Battery is staggered cooling-air flow has been played guide functions, improves the battery surface cooling-air flow and flows, and has improved battery pack heat-dissipation homogeneity.
