Description
Technical field
The application is related to cell art, and in particular to a kind of good battery pack that radiates.
Background technology
New-energy automobile is greatly developed in China, it is contemplated that the recoverable amount to the year two thousand twenty new-energy automobile is up to
5000000.Battery is also increasingly being applied to the occasion of the high power works such as electric vehicle.In practical occasion, battery
More by cell series connection and/or and use in the form of being unified into battery pack, the quantity of series/parallel from tens to, hundreds of very
To thousands of.For security protection and the requirement of installation, battery pack is typically disposed in shell made of metal, and outside is equipped with
Terminal.Space is used in order to improve the effective of automobile, it is desirable to reduce battery pack volume, cell are often arranged very tight
Close, this radiating for battery pack is very unfavorable.In latter stage of charging and high power work, internal storage battery meeting heat release, battery
The temperature of the cell in group centre position will be apparently higher than the temperature of the cell close to shell wall, the electrification that they show
Characteristic is different from other batteries, and the battery homogeneity obtained before assembling by a variety of effort has not just existed, this portion in use
Divide cell to be operated in overcharge, cross and put under state, performance fails rapidly, failure, causes under whole group battery performance
Drop even failure, failure.By the dissection and analysis of the batteries to be ended to cycle life, battery pack medium temperature height is also indicated that
Cell the residual capacity cell low well below battery pack edge temperature residual capacity, battery pack
Fail mainly due to caused by battery pack middle part the part often failure of the cell under high temperature.This results in electricity
The life-span of pond group is significantly less than the cycle life of cell.It is additionally, since in the battery pack to go out of use and also contains significant proportion
The cell for still having use value, also result in the waste of resource and the increase of use cost.
In order to improve the situation of existing cell non-uniform temperature during battery pack use, and then improve battery pack
Service life, there has been proposed various solutions.Various cooling devices are added such as in battery pack, wherein to be made with air
Air cooling equipment for cooling medium and the water cooling plant by the use of water as cooling medium are relatively conventional.But both modes there is
Need the deficiency of additional cooling medium recycle unit, there is provided the device of medium circulation power such as blower fan, water pump need to expend in itself
Electric energy and space-consuming, coolant guiding channel is also reserved in battery pack, this will increase the volume of battery pack, limit electricity
The riding position of pond group onboard.Also, after stopping, if turned off the power supply on car, the device such as blower fan, water pump will stop work
Make, it is impossible to ensure the sufficiently cool of battery pack.Just closed on blower fan, water pump and car after battery pack is sufficiently cool to realize
Power supply, then substantially to increase the complexity of electrical control, improve cost.

In the battery plug-in opening of battery bracket, a side wall flush arrangement of the collecting plate and the battery bracket.
The advantages of the application is：
1st, space is saved, avoids air cooling, the system equipment space requirement needed for water cooling.
2nd, the temperature uniformity of battery pack is improved, effect is significantly better than air cooling or water cooling.
3rd, avoid because the water vapour to be formed that colds and heat succeed each other is attached on battery, trigger the potential safety hazards such as short circuit.
4th, after the completion of assembling, flat hot pipe cooperates with each battery cell in battery pack and is tightly pressed together, so as to improve
The structural strength and stable degree of battery pack, effectively prevents battery cell from loosening.
5th, the phase-change material of encapsulation can arbitrarily flow in heat pipe in flat hot pipe, can quickly absorb electric everywhere around heat pipe
The heat of pond monomer, no matter which battery cell heat is too high, and all phase-change materials in that close heat pipe can
Absorb heat the heat of this battery cell, ensure that the homogeneity of each battery cell temperature in battery pack.
