The battery of battery heat exchanger.
Background technology
At present, vehicle becomes increasingly popular to be dissolved into the life of average family.However, conventionally employed burns gasoline or
The internal combustion engine of diesel oil needs to consume substantial amounts of petroleum-based energy, and the tail gas that engine emission comes out as the vehicle of dynamical system
The earth environment that we depend on for existence is generated and is seriously affected.In recent years, due to the worsening shortages and family expenses of petroleum-based energy
Vehicle becomes increasingly popular, these defects are more obvious.Just so, it is energy saving and environmentally friendly have become the important of China Automobile Industry
Direction.Main vehicle manufacturer all just concentrates one's energy to research and develop power source of the various fungible energy sources as vehicle in the world, such as wraps
Include using dynamical system of the energy as vehicle such as hydrogen, solar energy, wind-force.Wherein, using oil electric mixed dynamic or pure electricity
Dynamic electric power increasingly becomes the main trend of vehicle development as vehicle power source.
Using oil electric mixed dynamic or the vehicle of pure electric vehicle electric power, generally include at least one for driving vehicle
Motor and the power battery pack being arranged on vehicle chassis.Since lithium-ion-power cell is that to possess optimum capacity at this stage close
The power battery of degree and power density, therefore the power battery pack preferably comprises the lithium-ion electric of multiple lithium-ion electric cores
Pond group.
Since the electrolyte of lithium ion battery is organic solute, the electric discharge energy of lithium ion battery in the case of low temperature
Power is poor.If long-term forcible discharge at low temperatures, can cause the service life of lithium ion to decline rapidly.It is such as relating to electric
The technology energy of pond field of heat management is understood, and is discharged in battery higher than its limiting temperature and less than its limiting temperature
When, lithium ion battery is easily quickly scrapped.However, in the sales region and using area of hybrid power or pure electric vehicle often
Winter cold zone and summer sudden-heat area can not be excluded, environment temperature is often in the permission work of lithium-ion-power cell
Make outside temperature range.Therefore in this case it is desirable to which the battery for being additionally provided with an outside heats or radiator comes
Heat or radiate to lithium ion battery.
But existing heat exchanger of battery is there are the problems such as complicated, manufacture craft is cumbersome, and most of adopt
With single liquid stream heat exchange structure, it is merely able to absorb battery electric heating according to the liquid heat transferring medium flowed in heat exchanger of battery
Or for battery heat, once liquid heat transferring medium break down (for example can not flow), then will not be able in time to battery into
Row heat exchange is handled.
The content of the invention
The purpose of the application is：For above-mentioned technical problem, the application proposes a kind of new heat exchanger of battery and matches somebody with somebody
Put the battery of this heat-exchanger rig, the heat exchange property of the heat exchanger of battery is reliable and stable, can according to be actually needed it is quick and
Effectively lithium-ion-power cell group is heated or radiated.
The technical solution of the application is：
A kind of battery heat exchanger, including inflation plate, the inflation plate have upper and lower surface, and the inflation plate
In be provided with that inflation mode is formed and mutually isolated first flow and second flow channel, the first flow is in it
Closed flow equipped with heat absorption phase-change material, the second flow channel are the open channels for the liquid heat transferring medium that circulates.
This battery heat exchanger of the application based on the above technical solutions, further includes following preferred solution：
The first flow and second flow channel are both formed in the upper surface of the inflation plate.
The first flow is formed at the upper surface of the inflation plate, and the second flow channel is formed under the inflation plate
Surface.
A kind of battery, including battery body, further include the battery heat exchanger of said structure, the upper surface of the inflation plate or
Lower surface contacts arrangement with the battery body.
The upper surface of the inflation plate contacts arrangement with the outer surface of the battery body.
The first flow and second flow channel are both formed in the upper surface of the inflation plate, and the first flow and
Two runners are close to arrange with the battery body.
In general, the battery is battery pack.
The advantages of the application is：
This battery heat exchanger of the application by blowing-up technology formed two runners, one for closed flow and built with
Absorb heat phase-change material, and another flows liquid heat transferring medium for open channels and in it.During practical application, which is exchanged heat
Device and the adjacent arrangement of battery.
When battery temperature is higher, the liquid heat transferring medium that temperature is relatively low in second flow channel absorbs the heat of battery,
And the heat absorbed is taken out of.Meanwhile the phase-change material that absorbs heat in first flow also absorbs the heat of battery and is changed into from solid-state
Liquid, and the temperature of phase-change material itself will not rise.So ensure the temperature stabilization of battery in required scope.
When battery temperature is relatively low, temperature is of a relatively high in second flow channel liquid heat transferring medium release heat and to battery
Heated.Meanwhile the phase-change material that absorbs heat in first flow also releases heat and is changed into solid-state from liquid, and phase-change material is certainly
The temperature of body will not decline.So ensure the temperature stabilization of battery in required scope.
Even if liquid heat transferring medium breaks down and is unable to neither endothermic nor exothermic in second flow channel, the heat absorption in first flow
Phase-change material is still within effective status, so as to be maintained the temperature of battery.
Brief description of the drawings
In order to illustrate more clearly of the technical solution of the embodiment of the present application, required use in being described below to embodiment
Attached drawing be briefly described, drawings in the following description are only some embodiments of the present application, for the common skill in this area
For art personnel, without creative efforts, other attached drawings can also be obtained according to these attached drawings.
