A series of concept of reduced forms is introduced in Summary, this will in the detailed description section into
One step is described in detail.The key that this part of the disclosure is not meant to attempt to limit technical solution claimed is special
It seeks peace essential features, does not mean that the protection scope for attempting to determine technical solution claimed more.
Below in conjunction with attached drawing, the feature and advantage that the present invention will be described in detail.
Detailed description of the invention
Following drawings of the invention is incorporated herein as part of the present invention for the purpose of understanding the present invention.Shown in the drawings of this hair
Bright embodiment and its description, principle used to explain the present invention.In the accompanying drawings,
Fig. 1 is batteries of electric automobile infantees seated position schematic diagram；
Fig. 2 is the structural schematic diagram of IFP1 battery pack bottom case；
Fig. 3 is battery pack structure schematic diagram；
Fig. 4 is battery pack upper cover；
Fig. 5 is battery pack bottom case；
Fig. 6 is battery pack grid and inserting slot construction.
Specific embodiment
In the following description, the working principle of the invention and process description are given, in order to provide to the present invention more
Thoroughly understand.However, in other examples, in order to avoid confusion with the present invention, for more well known in the art
Technical characteristic is not described.
As shown in Figure 1, battery pack B is arranged between crew module A and the chassis of vehicle, air is by arrow direction, from vapour
The front deck of vehicle enters battery pack, and after cooling down to battery pack, heat is discharged from tail of the body.
As shown in Fig. 2, being the bottom case structure of IFP1 type battery pack, due to the defect in design, so that air enters battery
It comes into full contact with battery pack after packet, and is arranged closely between battery cell, cause air velocity in battery pack slow, because
This, the heat that battery generates when working can not be discharged in time, and the heat at battery pack rear portion and edge is constantly accumulated, and battery pack is caused
Battery temperature at edge and separate air intake is excessively high, and excessive temperature differentials between battery cell, cell discharge efficiency is greatly reduced, into
And electric car performance is caused to decline to a great extent.
As shown in figures 3 to 6, the present invention is by 1, grid, 2, deflector, 3, single power battery, 4, bottom case, 5, radiation air
Fan, 6, upper cover composition.Wherein, bottom case 4 is the rectangular case structure of top opening, and the top open-mouth of bottom case 4 is close by upper cover 6
Envelope, the upper cover 6 are fixed by screw and 4 phase of bottom case, are equipped with grid 1 in the front end of bottom case 4 and are added two in 1 two sides of grid
Block deflector 2,2 length of deflector are slightly shorter than 4 length of battery pack bottom case, and 2 front end of deflector and the two sides of grid 1 fit closely,
There are a distances away from 4 rear end of bottom case for 2 rear end of deflector, are mutually authenticated by emulating with test, optimum distance 40mm, water conservancy diversion
The width of plate 2 is consistent with the height of bottom case 4, and two pieces of deflectors 2 are separated out a flow-guiding channel through grid, by battery pack in
Between be divided into two parts, respectively install close to air intake direction in 4 two sides of bottom case there are two radiator fan 5, two of every side dissipate
Hot-air fan arrangement form is to arrange up and down.
As shown in figure 3, arrow direction is air direction of flow, cooling air enters battery pack, air by grid 1
The flow-guiding channel obstructed out by deflector 2 is flowed through, until the end of deflector 2, is shorter in length than bottom case 4 due to deflector 2
Overall length, cooling air are squeezed into the battery pack two sides where battery pack, the radiator fan 5 that the two sides of bottom case 4 install additional, to battery pack
Interior air is aspirated, and air is finally flowed out entrainment of the heat that battery pack generates by radiator fan 5.Install deflector 2 additional
Afterwards, flow path of the cooling air in battery pack is significantly increased, and the contact between battery cell also more sufficiently, is conducive to take away more
More heats, and due to the swabbing action of radiator fan 5, the flow velocity of air in battery pack is accelerated, when so that battery working
The heat of generation can be discharged outside battery pack faster, ensure that battery can work in good temperature range.
By improving, applicant has carried out experimental verification again, compared with IFP1 type battery pack, a kind of present invention: air
Heat radiating type batteries of electric automobile packet, maximum temperature when internal battery works have dropped about 6 DEG C, the high-temperature area of battery pack
Basic to disappear, battery pack bulk temperature is in 18-43 DEG C of optimum working temperature section, and the temperature difference reduces between battery cell
It 3.8 DEG C, can guarantee the discharging efficiency of battery pack 80% or more, illustrate that the invention has more outstanding air heat dissipation performance.
