Description
Technical field
The present invention is a kind of coldplate for new energy car battery heat management system, can be achieved battery and cold drawing it
Between high efficient heat exchanging, protect cell safety, improve battery operating efficiency.
Background technology
In electric automobile, electrokinetic cell is the energy-storage travelling wave tube of core, and the operating efficiency of battery directly influences vehicle
Distance travelled.Battery is in charge and discharge process, when it can export or input larger, the substantial amounts of heat in place can be discharged, if too late
When the temperature of battery is controlled, battery dieseling can be caused or even can be exploded.But traditional batteries of electric automobile
In heat management system, the cooling system of indirect cooling-type is usually using single aluminium sheet as battery cooling plate, and heat exchange efficiency is not
, there is the problem of can not radiating in time in height.
Heat pipe be using medium hot junction evaporate after cold end condense phase transition process (i.e. using liquid evaporation latent heat and
The latent heat of condensation), heat is quickly conducted.Heat pipe one end is evaporation ends, and other end is condensation end, when heat pipe one end is heated,
Liquid rapid vaporization in capillary, steam flows to other end under the power of thermal diffusion, and discharges heat in cold end condensation
Amount, liquid flows back to evaporation ends along porous material by capillarity again, and so circulation is more than, and until heat pipe two ends, temperature is equal.This
Plant circulation quickly to carry out, heat, which can be conducted continuously, to be come.
Traditional battery cooling plate is improved using hot pipe technique, the heat exchange efficiency of battery cooling plate can be improved, battery is maintained
Operating temperature protects cell safety in OK range, lifts battery operating efficiency.
The content of the invention
Present invention seek to address that the problem of common batteries coldplate exchange capability of heat is not enough, it is proposed that one kind application hot pipe technique
Battery cooling plate scheme.
A kind of plate-type battery coldplate of application hot pipe technique, including one block of L-type aluminium sheet and disposed above, neatly
The heat pipe of arrangement.The longer one side of L-type aluminium sheet is used for and plate-type battery is fully contacted；Battery by fixed block and heat conductive pad, and
Aluminium sheet is installed together, and constitutes a battery heat exchange unit.Heat pipe is arranged in the another side of L-type aluminium sheet, the shape and L-type of heat pipe
Aluminium sheet is adapted, and is also L-type.The evaporation segment length of heat pipe is corresponding with the height of battery, adiabatic segment length and L-type aluminium sheet bending
Part it is corresponding, condensation segment length and L-type aluminium sheet it is corresponding with cold drawing contact portion.It can arrange some on one block of L-type aluminium sheet
Individual heat pipe, each heat pipe proper alignment.
The thickness of the L-type aluminium sheet reduces as far as possible according to processing technology, on the one hand can save the system of single battery coldplate
Make cost, on the one hand can reduce battery cooling plate and take volume so that the heat exchange unit knot being made up of battery and battery cooling plate
Structure is more compact.
The heat pipe has one section of bending to flatten heat pipe, and its shape is also L-type, is adapted with L-type aluminium sheet.
The end of the heat pipe and the end of L-type heat pipe coincide.
Have refrigerant circulation inside the cold drawing, can take away by heat pipe transmission Lai heat.
The evaporation segment length of the heat pipe is corresponding with cell height, can fully absorb the heat of battery generation；Condensation segment
It is corresponding with L-type aluminium sheet and cold drawing contact portion, can fully absorb by cold drawing transmission Lai cold.Inside heat pipe evaporator section absorbs
Cell heat, liquid medium evaporation, flows to condensation segment；Medium realizes and exchanged heat that the liquid formed after medium condensation leads in condensation segment
Cross capillary and flow back to evaporator section, high efficient heat exchanging can be achieved in one closed circulation of so far inside heat pipe formation.
The invention has the advantages that：
1st, utilize the battery cooling plate heat exchange efficiency of hot pipe technique high, it is possible to resolve common coldplate radiating asking not in time
Topic.
2nd, battery cooling plate can and battery constitute a heat exchange unit.Each heat exchange unit structure, size is identical, after installation
Compact conformation, can make full use of space.
3rd, battery cooling plate is simple in construction, is easy to dismounting.
