Cylindrical cell, processing technology is ripe, with low cost, is beneficial to the large-scale application in market, but the form of cylindrical cell composition battery pack is more difficult and temperature homogeneity between multiple cell is difficult to the problem that ensures.
Innovation and creation content
The problem to be solved in the present invention is to provide one and is conducive to cylindrical cell and more easily forms battery pack, and structure is simple, good heat conduction effect, and internal temperature evenly and be convenient to the battery pack structure implemented.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of battery pack structure, comprise housing shell, heat transmission fin plate and the batteries be made up of multiple cylindrical cell, the inside of the described housing shell that left and right end face is open is provided with the accommodation cavity of cuboid, the middle part of described housing shell upper surface is provided with symmetrical two electrodes, the left and right end face being arranged on described housing shell closed by described heat transmission fin plate, inner side end perpendicular to described heat transmission fin plate is provided with the corrugated corrugated fin in the sensing described accommodation cavity direction of upper and lower run-in index layering, and the ripple radius of described corrugated fin is consistent with the radius of single described cylindrical cell, described batteries correspondence is placed on described corrugated fin by shifting to install in the accommodation hole of formation up and down, described batteries is electrically connected with described electrode, heat-conducting filler is filled with in space between described batteries and the described accommodation cavity of described housing shell.
Further, described heat-conducting filler is heat conduction glue.
Further, the middle part of described housing shell upper surface has circular upper end face plate hole.
Further, the outer surface of described housing shell is provided with the crosslinked polyetylene insulated layer of one deck.
Further, described housing shell is the protective case be made up of the cutting of rigid insulation plastic plate.
Further, described corrugated fin middle part along ripple flow to direction have vertical masonry joint on corrugated fin.
Further, it is one-body molded that described heat transmission fin plate passes through section steel cutting by copper or aluminium, is preferably by aluminium section bar excision forming herein.
The advantage that the present invention has and good effect are: adopt technique scheme, the ripple radius having benefited from the corrugated corrugated fin that heat transmission fin plate is arranged is consistent with the radius of single cylindrical cell, the accommodation hole that the corrugated fin shifted to install up and down of housing shell both sides is formed can hold cylindrical cell, and each cell is very firm by what grip, overall structure very compact again, contribute to the cylindrical cell composition battery pack being not easy to form battery pack, and the contact of cylindrical cell and the corrugated fin of each composition batteries fully and even, good heat conduction effect, dispel the heat also more even, by the upper end face plate hole that the upper surface of housing shell has, the heat conduction glue that heat conductivility is good can be poured into, contribute to the space of heat-conducting glue water conservancy gravity from top to bottom fully between filling batteries and the accommodation cavity of housing shell, the middle part of corrugated fin along ripple flow to the corrugated fin that has of direction on vertical masonry joint contribute to the circulation of heat conduction glue, make heat conduction and heat radiation all more abundant, the housing shell be made up of the cutting of rigid insulation plastic plate has enough mechanical strengths, and itself also has certain electrical insulating property, use safety, can not be breakdown, the crosslinked polyetylene insulated layer that the outer surface of housing shell is provided with, can play the effect of further reinforced insulation isolation.
