Background technique
It is serious with global pollution, realize the problem of emission reduction becomes global concern, automobile substitutes petroleum using new energy
Equally it is concerned.Energy source is utilized the battery as, being combined into battery pack with serial or parallel connection more piece single battery, (battery is simultaneously
Connection can provide stronger electric current；Battery series connection can provide higher voltage), battery pack has stable voltage and current, no
Influenced vulnerable to the external world, can long-time stable power supply, and realize zero-emission using battery replacing gasoline as power source.But
In use due to battery pack, biggish heat can be gathered in the power battery of especially compact-sized high-energy density
Amount, influences the stability of battery, there are security risks, therefore its thermal diffusivity is an important quality requirements.
Mostly use liquid cooling or air-cooled radiating mode in the prior art, such as application No. is CN201310450674.7
Patent application disclosed by technical solution, be connected to heat exchanger assembly (23) using heat pipe (24) and be connected to coolant liquid, it is cold
But liquid is circulated in heat pipe (23) and heat exchanger assembly (24), to distribute the heat of battery component generation.Electric car continues
Boat mileage problem proposes higher requirement to power battery pack, since the space of vehicle is limited, in order to improve electronic vapour
Vehicle course continuation mileage needs to place more battery as far as possible in a limited space, but as occupied by the arrangement of the prior art
Space is larger, is not well positioned to meet this demand；Simultaneously because the relied on heat exchange of battery pack heat dissipation in the prior art
The coolant liquid stored in component (24) is limited, and not additional cooling device, heat dissipation effect are not very ideal yet.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of improved power battery module structures, including rectangular battery pack
Cabinet, radiator, the radiator include being overlying on copper heat sink at the top of battery case body, multiple perpendicular to battery
The copper thermal column of the group bottom of box, thermal column upper end is abutted with heat sink bottom surface；It further include consolidating below heat sink
Fixed board, the fixed plate are consistent and parallel with heat sink with the top surface size of battery case body;Multiple confessions are placed in fixed plate
The opening of thermal column insertion, the opening shape on the section and fixed plate of thermal column are cross, on thermal column and fixed plate
Opening be in ranks arrangement and correspond, thermal column can be inserted into fixed plate on corresponding opening in, cylindrical battery monomer
It can be placed between thermal column and be close to the side of thermal column.
Preferably, the battery case body bottom is equipped with and the cylindrical battery monomer bottom pair that is put into battery pack box body
The cylindrical boss answered forms the gap adaptable with the section of thermal column between boss.
Preferably, the thermal column center is equipped with through-hole.
Preferably, the fixed plate is aluminum.
The present invention provides a kind of improved power battery module structure, is radiated by the way that cross is arranged in battery pack box body
Column, after battery cell is packed into battery pack box body with can thermal column and heat sink realization flash heat transfer, and make full use of cylinder
Gap between battery cell, guarantee it is compact-sized to realize high-energy density while, improve heat-sinking capability, and by solid
Fixed board guarantees the firm of thermal column installation.
Detailed description of the invention
Fig. 1 is improved power battery module structure example structure schematic diagram provided by the invention.
Fig. 2 is improved power battery module structure example structure explosive view provided by the invention.
Specific embodiment
In order to facilitate the understanding of those skilled in the art, making the utility model into one below in conjunction with attached drawing and embodiment
Step detailed description.
A kind of improved power battery module structure as shown in Figure 1, 2, including battery case body 1, battery case body top
Equipped with a copper heat sink 3, using snapping connection between heat sink and battery case body, it is additionally provided in battery pack box body multiple
Perpendicular to the copper thermal column 4 of battery case body bottom, thermal column upper end is abutted with heat sink bottom surface；Thermal column and heat dissipation
Fixed plate 2 is additionally provided between plate, fixed plate is consistent and parallel with heat sink with the top surface size of battery case body;It is arranged in fixed plate
Multiple openings for thermal column insertion are furnished with, the opening shape on the section and fixed plate of thermal column is cross, thermal column
It is in ranks arrangement with the opening in fixed plate and corresponds, thermal column can be inserted into the corresponding opening in fixed plate, fixed
Plate fixes the position of thermal column, and cylindrical battery monomer 5 is inserted between thermal column and is close to the side of thermal column, from
And it is vertically placed to battery case body bottom.For the installation for further consolidating thermal column, battery case body bottom is equipped with and is put into electricity
The corresponding cylindrical boss in pond group case intracorporal cylindrical battery monomer bottom, forms between boss and the section of thermal column is mutually fitted
The gap answered can be inserted into the boss of battery case body bottom when thermal column is inserted into the gap between cylindrical battery monomer simultaneously
Between, to improve the firmness of installation.
Cross thermal column, when so that cylindrical battery monomer being put into battery case body, thermal column surface is arranged in the present invention
Be close to battery cell surface, increase thermal conductive contact area, and thermal column and heat sink be all made of the preferable copper of heating conduction at,
Flash heat transfer may be implemented, fixed plate is aluminum, will not be the whole additional increase of modular structure while guaranteeing heat-transfer effect
Too many weight.
In addition, design has cavity in heat sink, and heat dissipation board ends are respectively equipped with and cavity to further increase heat dissipation effect
The water inlet pipe and outlet pipe of connection, water inlet pipe are equipped with internal screw thread, and outlet pipe is equipped with corresponding external screw thread, can be connected to outside
Cooling device, flowed through by injecting coolant liquid to improve radiating efficiency inside heat sink, and the internal and external threads of inlet and outlet pipes are set
Meter, can facilitate the heat sink of multiple battery packs to be connected to, convenient when multiple battery combinations use to connect with external cooling device
It is logical.
The above are wherein specific implementations of the invention, and the description thereof is more specific and detailed, but can not therefore manage
Solution is limitations on the scope of the patent of the present invention.It should be pointed out that for those of ordinary skill in the art, not departing from
Under the premise of present inventive concept, various modifications and improvements can be made, these obvious alternative forms belong to this hair
Bright protection scope.Details not described in detail in the present invention can be selected any prior art and realize.
