Fig. 1 is the perspective view of fin in the embodiment of the present invention;
Fig. 2 is the vertical view of high capacity cell in the embodiment of the present invention;
Fig. 3 is the perspective view of high capacity cell in the embodiment of the present invention, conveniently reader understanding's technical scheme of the present invention, has two cylindrical cells to be removed in figure;
Wherein: 1-fixture, the cylindrical cell of 2-, 3-longitudinal slot, 4-transverse slot, 5-fin, 5a-boss, 6-elastic conducting backing, concaved circular cambered surface in 6a-.
Embodiment
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the present invention limit the scope of the invention.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
Fig. 1 to Fig. 3 shows a this specific embodiment with the high capacity cell of heat abstractor of the present invention, identical with Conventional mass battery, this high capacity cell also comprises fixture 1, be arranged on this fixture and several cylindrical cells 2 of arranged in parallel and many longitudinal slots 3 be formed between these cylindrical cells and many transverse slots 4.The present embodiment said " longitudinal direction " and " transverse direction " are comparatively speaking, the two is orthogonal both direction, in order to express easily, this example take Fig. 2 as benchmark, the left and right directions being parallel to paper is in fig. 2 defined as this example said " transverse direction ", and the above-below direction being parallel to paper is in fig. 2 defined as this example said " longitudinal direction ".Certainly, if the left and right directions being parallel to paper in Fig. 2 also can be defined as " longitudinal direction " by we, and the above-below direction being parallel to paper in Fig. 2 is defined as " transverse direction ".
The key improvements of the present embodiment is: in described transverse slot 4, be inserted with fin 5.Described fin 5 can only arrange one piece, also can arrange polylith, and its quantity is not limit.In order to improve the heat dispersion of this high capacity cell substantially, preferably in every bar transverse slot 4, all plug one piece of fin 5.
During practical application, only can plug fin 5 in longitudinal slot 3, also only can plug fin 5 in transverse slot 4, can also all plug described fin 5 in longitudinal slot 3 and transverse slot 4.
This example is provided with multiple elastic conducting backing 6 on fin 5, and these elastic conducting backings 6 have the interior concaved circular cambered surface 6a pressing and be fitted in cylindrical cell 2 outside wall surface.These elastic conducting backings 6 with interior concaved circular cambered surface 6a that fin 5 is arranged, can avoid fin 5 to occur to loosen on the one hand, can increase the heat transfer area of cylindrical cell 2 on the other hand, to accelerate the heat transmission of fin 5 pairs of battery cells.
In order to ensure that elastic conducting backing 6 can perfect fit with cylindrical cell 2, or the approximately equal equal with the radius of curvature of described cylindrical cell 2 outside wall surface of the radius of curvature of interior concaved circular cambered surface 6a described in this example.
In this example, described fin 5 forms the boss 5a that side direction is protruded, boss 5a and fin 5 are structure as a whole, and described elastic conducting backing 6 is fixed on described boss 5, so can ensure fin 5 and elastic conducting backing 6 bulk strength.
In this example, described boss 5a is with the arcwall face of an indent, and elastic conducting backing 6 is fixed on the arcwall face of this boss 5a, as Fig. 1.
During assembling, fin 5 is aimed at the transverse slot 4 (or longitudinal slot 3) on high capacity cell, and the elastic conducting backing 6 on fin 5 is alignd with cylindrical cell 2.Then fin 5 is inwardly inserted transverse slot 4, and then in the outside wall surface interior concaved circular cambered surface 6a on each elastic conducting backing 6 all being pressed be fitted in cylindrical cell 2, as shown in Figures 2 and 3.
In order to ensure that fin 5 can insert in transverse slot 4 on high capacity cell or longitudinal slot 3 by assembly crewman very easily, when avoiding inserting fin 5, fin is stuck in high capacity cell outside, and this example is shaped with lead-in chamfered 7, as Fig. 1 on described boss 5a and elastic conducting backing 6.
This example is provided with elastic conducting backing 6 (the positive and negative both sides of fin 5 all form outwardly described boss 5a) in the positive and negative both sides of described fin 5, so make fin 5 and the cylindrical cell 2 all energy good contacts being positioned at its positive and negative both sides, the radiating efficiency of further raising high capacity cell, as Fig. 2.
Described elastic conducting backing 6 can adopt the good flexible material of various heat conductivility to make, such as silica gel.
During practical application, generally described fin 5 need be connected with corresponding radiator, during work, most of heat that cylindrical cell 2 produces passes to described radiator through elastic conducting backing 6 and fin 5 successively, then is absorbed by radiator and discharge.
Certainly, above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to people can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
