The heat dissipation technology of battery pack is all a great problem in electric car field all the time, is dissipated used by the prior art
Hot method mainly has air blast cooling and two kinds of liquid cooling.Wherein simple air blast cooling is in most cases due to battery pendulum in battery pack
The positional relationship put, the air inlet battery temperature that will lead to battery pack is lower, and exit battery temperature is higher, i.e. battery pack
Interior temperature distributing disproportionation, to influence battery with two side terminals.And if simply use the mode of liquid cooling, although cooling effect compared with
It is good, but the internal structure of battery pack is complicated, will lead to the increase of battery pack weight and cost.
Summary of the invention
In view of the defects existing in the prior art, the object of the present invention is to provide a kind of good heat dissipation effect, structures simply, cost
Low mixing heat dissipation type power battery pack.
A kind of mixing heat dissipation type power battery pack, including battery modules in cabinet are set to, the bottom of the cabinet is equipped with water
Slot, tiling has the first heat-conducting silica gel sheet between battery modules and sink；The tank ends offer respectively air inlet and
Air outlet；The second heat-conducting silica gel sheet is equipped in the battery modules between two neighboring single battery.
Further scheme, the box house are separated into two rectangle cavitys, length of the battery modules along rectangle cavity
The diagonal line in degree direction is successively intervally arranged, and forms step structure.
Further scheme, one end of the rectangle cavity offers the air inlet communicated with its inner cavity, the other end is opened
Equipped with the air outlet communicated with its inner cavity；The air inlet and air outlet with the step structure that is made of battery modules
Step surface communicates.
Further scheme, the air inlet and air outlet are strip；The air inlet and air outlet are equipped with filtering
Net.It avoids sucking rubbish clast and influences the normal work of battery.
The bottom end of further scheme, second heat-conducting silica gel sheet is connected with the first heat-conducting silica gel sheet.
Further scheme offers to the pairs of linea angulata in the both ends of the sink inlet and outlet, the water inlet position
In on the sink of air outlet side, water outlet is located on the sink of air inlet side.
The present invention is radiated by the recirculated water of forced air convection and battery pack bottom inside battery pack.
Battery modules are diagonally intervally arranged and form step structure by the present invention, and stay between adjacent cell mould group
It has the gap, for the parallel circulation of convected air, can reduce conventional air-cooled caused temperature distributing disproportionation problem.
Being located at the first heat-conducting silica gel sheet between battery modules and sink can transmit rapidly the heat that battery modules generate
Into recirculated water, radiate to battery pack.The second heat-conducting silica gel sheet is posted in battery modules between neighboring unit cell, and will
It connect with the first heat-conducting silica gel sheet being laid on sink, so that the amount of heat on single battery center surface is transferred to
First heat conductive silica gel on piece；In addition, the first heat conductive silica gel on piece is laid on sink, since the material of sink and cabinet is to lead
Hot good metal material can promptly take away the heat of the first heat conductive silica gel on piece.
The pairs of linea angulata setting of the inlet and outlet of sink, accelerates the circulation of water, improves cooling effect.In addition, by water
The water inlet setting of slot is in air outlet side, and water outlet is arranged in air inlet side, to be conducive to equably to battery pack
Two sides cool down, and ensure that the consistency of battery pack two sides temperature.
