Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
For solving lithium cell heat radiation and a safe battery container, structure as shown in fig. 3 to 7, comprises housing body, housing body leaves the opening of placing battery; The side of housing body is provided with some circles first to dispel the heat convex edge 1, each encloses between the first adjacent heat radiation convex edge 1 and be arranged in parallel; On the side of housing body along and the first vertical direction, convex edge 1 of dispelling the heat to be arranged in parallel respectively the second heat radiation convex edge 2; Spacing between each circle first heat radiation convex edge 1 and the spacing between the second heat radiation convex edge 2 set according to actual conditions.
Some grooves 4 are set respectively in the corresponding position of each circle first heat radiation convex edge 1, groove 4 first heat dissipation channel 5 that the through battery container of composition is upper and lower jointly at each circle first heat radiation opposite position place, convex edge 1.
Bottom surface relative with the opening of placing battery in housing body is arranged the some 3rd to dispel the heat convex edge 3.The 3rd heat radiation arrangement of convex edge 3 and composition situation can be arranged according to actual needs voluntarily, the intersection between layouts, heat radiation convex edge or be arranged vertically or the combination etc. of above-mentioned two kinds of modes of being parallel to each other between convex edge of such as dispelling the heat.The structure of the 3rd heat radiation convex edge 3 of the present embodiment as shown in Figure 7.
During every two battery containers contact, due to the docking of the first heat radiation convex edge 1, the face that two battery containers contact can form some spaces communicated, and these spaces define some second heat dissipation channels 6 about through battery container.
In the edge in each face of battery container, the first heat radiation convex edge 1 or the second heat radiation convex edge 2 is set respectively accordingly, avoids the close contact on battery module housings surface, be more conducive to heat radiation.
Dispel the heat convex edge 2 and the 3rd heat radiation convex edge 3, first heat radiation convex edge 1, second can be arranged respectively to square, trapezoidal, circular arc or dihedral, preferred shape is square, be convenient to docking and heat radiation between battery with battery, be more conducive to mould molding, cost-saving.This gives the first heat radiation convex edge 2, heat radiation convex edge 1, second and the 3rd heat radiation convex edge 3 and be all set to square structure.
Above structure makes battery casing surface all can realize heat radiation, battery in groups after, when more than 2 and 2 battery containers are assembled into battery pack, design because single housing four sides all possess the first heat radiation convex edge 1, convex edge 1 is dispelled the heat by docking in housing and body contact place first, thus form some square second heat dissipation channels 6, owing to all arranging groove 4 at the opposite position place of each circle first heat radiation convex edge 1, groove 4 composition first heat dissipation channel 5 jointly at opposite position place, upper and lower to realize battery pack, left and right, the function all can dispelled the heat in front and back, as seen in figs. 8-10.
The design of the first heat radiation convex edge 1 and the second heat radiation convex edge 2, avoids battery module housings intimate surface contact, prevents battery pile heat accumulation and affect battery and fail safe, and is convenient to the heat dissipation design such as battery pile is air-cooled.
The design of the heat radiation convex edge on battery container, forms square lines at surface of shell, is convenient to installation personnel carrying, picks and places, and can improve module shock resistance and mechanical strength better.
The wall thickness of the square groove 7 surrounded by the first heat radiation convex edge 1 and the second heat radiation convex edge 2 is less than the wall thickness of the first heat radiation convex edge 1 and the second heat radiation convex edge 2, it is the relative weakness of housing, battery after being packed by housing causes the quick flatulence of battery because of collision or the factor such as short circuit, and when acquiring a certain degree, square groove 7 is more easily by spalling, and because of housing high sealing, high strength (as the packaging such as box hat, aluminum hull) and produce blast, the fail safe that battery uses can not be contributed to.
Due to the heat radiation convex edge that battery casing surface is arranged, what make the inwall of battery container it goes without doing is very thick, relatively reduce the thickness of inner walls, when battery flatulence arrives to a certain degree, inwall can directly break, prevent from, because the blocked up instantaneous explosion caused of battery inwall, improving the safety in utilization of battery.
What housing design employing was synthesized for primary raw material by nylon-66 etc. has corrosion-resistant, high temperature resistant, good insulating, high tenacity resinae material, solve the battery core electrolyte packed because of aluminum plastic film etc. better to reveal, improve battery pile antidetonation and the characteristic such as impact resistant, extruding; Meanwhile, because housing adopts resinae material, effectively avoid battery explosion, improve battery security.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection range; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection range of the present utility model.
