Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model battery pack and useful technique effect thereof are elaborated, wherein:
Fig. 1 is the schematic top plan view of the utility model battery pack.
Fig. 2 is that Fig. 1 is along the profile of A-A direction.
Embodiment
In order to make goal of the invention of the present utility model, technical scheme and useful technique effect more clear, below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.Should be understood that, the embodiment of describing in this specification is only in order to explain the utility model, is not in order to limit the utility model.
See also shown in Figure 1ly, the utility model battery pack comprises a plurality of battery cells 1 and adjustment module.Wherein, the battery pack outside can arrange battery case body 6, and battery cell 1 carries out the connection in series-parallel setting as required; For avoiding battery cell 1 both positive and negative polarity to cause the battery pack short circuit with contacting of battery case body 6, the pole of battery cell 1 can carry out insulation processing, and battery cell 1 can pack to guarantee battery cell 1 and 6 insulation of battery case body with dielectric film simultaneously.
Please coordinate and consult shown in Figure 2ly, the adjustment module comprises distributor 3, horizontally disposed first flow 4 and the second runner 5 and vertically disposed the 3rd runner 2.
The shape of cross section of the 3rd runner 2 is rectangular configuration, and the width d of rectangle is 0.5mm-20mm.The 3rd runner 2 is vertically set between adjacent battery cell 1, and the gap location between itself and battery cell 1 is filled with heat-conducting glue.Heat-conducting glue can be heat conductive silica gel, heat-conducting silicone grease or heat conduction casting glue.
Distributor 3 is located at the top of battery cell 1, its inner cavity that forms.The upper end of the 3rd runner 2 is inner and be connected with the cavity of distributor from the bottom embedding distribution device 3 of distributor 3, and insert depth h is 0.1mm-10mm.
First flow 4 and the second runner 5 are located at respectively top and the bottom of battery cell 1, and its cross sectional shape can be rectangle or circular configuration.First flow 4 is communicated with the cavity of distributor 3, is connected with Battery case circulating driving device outlet outward simultaneously; The second runner 5 is connected with the lower end of the 3rd runner 2, is communicated to simultaneously the entrance of circulating driving device.
The material of distributor 3, first flow 4, the second runner 5 can be selected the metal materials such as stainless steel, aluminium alloy, also can select the good plastic material of heat resistance.The material of the 3rd runner 2 can aluminium alloy sheets or corrosion resistant plate, and smooth surface can be made in its surface, also fin can be set, and the structure of fin can be that discontinuous fin also can be arranged to herringbone wavy fin.
The operation principle of said temperature adjustment module is: use the outer loop drive unit with the flow of 0.01-1.5L/s to the battery pack delivered inside cooling or heating liquid, generally, cooling or heating liquid mixed liquor, the heat conduction wet goods heat conductivility liquid preferably that can make water, water and ethylene glycol; Cooling or heating liquid enters distributor 3 via first flow 4, when the height of cooling or heating liquid during higher than the upper end of the 3rd runner 2, cooling or heating liquid enters the 3rd runner 2 and circulation downwards under the effect of self gravitation, and be the falling film type liquid film of 0.001-0.5mm at the inner surface formation average thickness of the 3rd runner 2, this falling film type liquid film can arrive other battery cell with the heat Fast-Balance that produces in battery pack, perhaps carries out cooling to battery cell or heating; Then, cooling or heating liquid enters the second runner 5 and exports battery pack via the second runner 5.
