Body.
Background technique
Now, new-energy automobile has come into huge numbers of families, and increasingly by public approval.Many fuel oil car owners in view of
The oil price to soar now, new-energy automobile of also all starting with one after another become the new-energy automobile car owner to grow with each passing hour.But with
The increase of new-energy automobile sales volume, customer complaint problem is also following, complaint be at most why new-energy automobile long-play
When, power exports " weakness " sometimes, continues not as good as the power output of fuel vehicle.Originally, this be vehicle factor due to safety concerns and
A kind of strategy deliberately designed.It is known that battery core can generate heat when power battery continues charge and discharge, when these heats are held
There is no good modes and approach to discharge as early as possible for continuous accumulation, will result in heat history, causes battery system temperature excessively high
And the output power of power battery is limited, so electric car just will appear power output " weakness " imagination.
New-energy automobile also divides high, medium and low with vehicle, removes in high-equipped vehicle model and part and is equipped with vehicle power battery pack
The equipped power battery of new-energy automobile of liquid cooling system, remaining configuration is all made of traditional natural cooling mode, this is resulted in
One of the reason of above problem.
Currently, the electrokinetic cell system water proof and dust proof grade of industry is almost substantially accomplished IP68 level, for outside
It is exactly a closed world for environment, in power battery cabinet, how the intracorporal heat of case is quickly passed into external rings
Border, and the sealing effect of cabinet is not destroyed, this is that industry is considering the problems of always.
In view of the above problems, a kind of novel power battery packet heat radiation box is developed, by the way that phase-change material is sprayed power electric
The mode of pond box outer surface makes power battery pack become active heat removal from original passive heat dissipation.
Utility model content
The purpose of this utility model is to provide a kind of novel power battery packet heat radiation boxes, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of novel power battery packet heat radiation box, including shell, the hull outside are coated with heat dissipating layer, the heat dissipation
Layer includes phase-change material layers and heat dissipation oil lamella, and the phase-change material layers and heat dissipation oil lamella form an entirety, the heat dissipation
Oil film is placed on the outside of the phase-change material layers.
As the further scheme of the utility model, the phase-change material layers with a thickness of 40 ± 5 μm.
As the further scheme of the utility model, the thickness of the heat dissipation oil lamella is less than the thickness of phase-change material layers.
As the further scheme of the utility model, anticorrosion with painting paint or plate armour on the outside of the oil lamella that radiates.
As the further scheme of the utility model, phase-change material temperature threshold value that the phase-change material layers use is 27
℃-40℃。
As the further scheme of the utility model, the phase-change material is microencapsulated phase change material.
As the further scheme of the utility model, the enclosure interior is equipped with heat transfer path, the heat transfer path connection
Battery core and shell.
Phase-change material is sprayed on the outer surface of power battery cabinet by the utility model, utilizes phase-change material heat liquid
Change, the material property of liquefaction heat absorption, the heat of power battery pack box house is adsorbed onto material, that is, is adsorbed onto dynamic
On the outer surface of power Battery case, then surface radiating oil reservoir crossed by phase-change material specially treated, will adsorbed on the surface of the housing
Heat be dispersed into external environment, to realize the heat exchange of power battery box inside and outside.
When power battery long-time or high current charge-discharge, power battery box interior temperature constantly accumulates raising, when
When temperature increases certain threshold value, heat is transmitted to phase-change material layer region through power battery tank shell, due to phase-change material layers
Very sensitive to temperature, heated form can pull up a horse and become liquid from solid-state, and substance liquefaction process is endothermic process, this just makes
A large amount of heat is absorbed by phase-change material layers inside power Battery case, and in heat transfer to heat dissipation oil lamella, heat dissipation is oily
Film layer is due to repulsion thermal properties itself, by conduct heat away into environment, at this point, phase-change material layers lose heat, form
Solid-state is become from liquid.
Above-mentioned radiation processes, as long as temperature is increased to certain threshold value, radiation processes carry out automatically, and temperature is lower than threshold value
When, due to not reaching the temperature threshold of phase-change material metamorphosis, heat dissipation without.
Compared with prior art, the utility model has the beneficial effects that
Compared with traditional natural cooling cabinet, which greatly accelerates power battery box inside and outside heat
Transmission speed, and thermaltransmission mode is become into active heat removal mode from passive radiating mode, realize that the automatic of Battery case dissipates
Thermal process.
