Key.
Fig. 6 shows the partial side view of the heat abstractor of existing cell.As shown in Figure 6, this cell 1
Heat abstractor includes hydroecium 2, heat-conducting plate 3 and thermal conductive silicon rubber cushion 4.Wherein, cell 1 includes battery frame 1a and sets
Putting the battery core unit 1b in battery frame 1a, hydroecium 2 is fixed on one end of battery frame 1a, and silicagel pad 4 is arranged on hydroecium 2
And between battery frame 1a, thermal conductive silicon rubber cushion 4 is fitted hydroecium 2.Heat-conducting plate 3 includes and the flat part of battery core unit 1b laminating
3a and turn-up portion 3b with thermal conductive silicon rubber cushion 4 laminating, turn-up portion 3b is bent to battery frame 1a from one end of flat part 3a
One end and thermal conductive silicon rubber cushion 4 between, a side of turn-up portion 3b is arranged on one end of battery frame 1a and is provided by
Support, another side laminating thermal conductive silicon rubber cushion 4.
Owing to heat-conducting plate 3 and hydroecium 2 are rigid structure, contact between the two mostly is linear contact lay, is therefore arranged on heat conduction
Thermal conductive silicon rubber cushion 4 between plate 3 and hydroecium 2 can fill the gap between hydroecium 2 and heat-conducting plate 3, increases thermal conductive contact
Area.But owing to the heat transfer efficiency of thermal conductive silicon rubber cushion 4 is limited, there is no the heat management that hydroecium 2 directly contacts with heat-conducting plate 3
Efficiency is high, the heat management limited efficacy of the most this structure.
In order to solve heat-conducting plate and cell in prior art can not the technical problem of good contact, the invention provides one
The heat abstractor of cell, it is able to ensure that the good contact of heat-conducting plate and cell.
Fig. 7 is the battery modules partial side view in one direction of the present invention.Fig. 8 is dissipating of the cell of the present invention
The structural representation of thermal.Shown in Fig. 7 and Fig. 8, present embodiments providing a kind of battery modules 30, it includes one
Individual or multiple cells 10, and the heat abstractor 20 for cell 10.Wherein, cell 10 includes electricity
Pond frame 11 and the battery core unit 12 in battery frame 11.
Heat abstractor 20 includes:
Hydroecium 21, hydroecium 21 is fixed on one end of battery frame 11；
Heat-conducting plate 22, heat-conducting plate 22, for the conduction of heat between battery core unit 12 and hydroecium 21, therefore combines shown in Fig. 7,
Heat-conducting plate 22 has and the flat part 22a of battery core unit 12 laminating, and turn-up portion 22b of laminating hydroecium 21.Wherein, turn over
Edge 22b is bent between one end of battery frame 11 and hydroecium 21 from one end of flat part 22a；With
Foam 23, foam 23 is filled in the space between one end of turn-up portion 22b and battery frame 11.
Wherein, during hydroecium 21 can be arranged into the Heat transfer systems of the battery modules shown in Fig. 1.
As it is shown in fig. 7, in the present embodiment, heat-conducting plate 22 is directly contacted with hydroecium 21 by turn-up portion 22b, to guarantee
The conduction of heat between battery core unit 12 and hydroecium 21 can be ensured to greatest extent.Have resilient foam 23 to be filled with and turn over
Space between one end of edge 22b and battery frame 11, thus provide the support force towards hydroecium 21 direction for heat-conducting plate 22,
To ensure good contacting between heat-conducting plate 22 and hydroecium 21.
Further, shown in Fig. 7 and Figure 10, the bearing of trend of hydroecium 21 hangs down with the bearing of trend of battery core unit 12
Directly, the angle α between turn-up portion 22b and flat part 22a is more than 90 °, is fixed on one end of battery frame 11 at hydroecium 21
Time, due to the laminating of hydroecium 21 with turn-up portion 22b, turn-up portion 22b is extruded by hydroecium 21 towards one end of battery frame 11,
So that there is elastic deformation in foam 23, the space being filled between one end of turn-up portion 22b and battery frame 11 due to foam 23
In, therefore foam 23 can produce elastic force turn-up portion 22b extruded towards hydroecium 21.
If the angle α between turn-up portion 22b and flat part 22a is equal to 90 °, i.e. turn-up portion 22b and hydroecium 21
Parallel, then contact to realize the laminating between turn-up portion 22b with hydroecium 21, need between heat-conducting plate 22 and hydroecium 21
Very close to each other and good contact between the highest installation accuracy guarantee turn-up portion 22b and hydroecium 21.And in this enforcement
In example, the angle α between turn-up portion 22b and flat part 22a is more than 90 °, i.e. turn-up portion 22b tilts towards hydroecium 21.
Then when hydroecium 21 is fixed to one end of battery frame 11, owing to turn-up portion 22b tilts towards hydroecium 21, hydroecium 21 is inevitable
Turn-up portion 22b is extruded so that it is move to parallel with hydroecium 21 towards one end of battery frame 11 towards one end of battery frame 11
Position, heat-conducting plate 22 is typically certain elastic metal material and makes, and therefore turn-up portion 22b is at elastically-deformable work
There is under with the trend moved towards hydroecium 21, thus ensure the good contact of turn-up portion 22b and hydroecium 21.
Further, having resilient foam 23 owing to filling between one end of turn-up portion 22b and battery frame 11, it is for turning over
Edge 22b provides and supports, then towards the mobile extruding foam 23 of battery frame 11 and make it produce elastic shape in turn-up portion 22b
Becoming, therefore foam 23 produces the elastic force towards hydroecium 21 to turn-up portion 22b, to be further ensured that turn-up portion 22b and hydroecium
The good contact of 21.So, heat-conducting plate is caused due to the angle α between turn-up portion 22b and flat part 22a more than 90 °
22 self elastic deformation and the elastic deformation of foam 23, the elastic force that these elastic deformations are provided ensure that turn-up portion
22b and hydroecium 21 realize good plane-plane contact, to ensure maximum heat management efficiency.
Through test, the angle α between turn-up portion 22b and flat part 22a is 91 °.
As shown in Figure 8 and Figure 11, one end of battery frame 11 farther includes securing member 13, owing to being fixed on by hydroecium 21
On one end of battery frame 11.Wherein, securing member 13 includes:
Draw-in groove 13a, draw-in groove 13a are positioned at the side of this end face of battery frame 11, with the side of clamping hydroecium 21；With
Elastic fastening hook 13b, elastic fastening hook 13b are positioned at the opposite side of this end face of battery frame 11, with another of clamping hydroecium 21
Side.
