Shell internal cavity is divided into upper heat radiation chamber, middle level chamber and lower heat radiation chamber by plate, and connecting between battery has connection sheet, battery
Some heat radiation breathers, heat radiation breather connection upper heat radiation chamber and lower heat radiation chamber, upper heat dissipation cavity it is vertically arranged with between core
Room is provided with air inlet, and lower heat radiation chamber is provided with exhaust outlet.Above-mentioned design is only for small cylindrical battery, and cannot meet
Under special operation condition, the requirement of battery heat radiation, can affect the cycle life of battery, be unfavorable for life-time service.
Wind-cooling heat dissipating typically uses the fan that battery system is built-in or external, dissipates battery core producing forced convertion
Heat, this type of cooling can increase the risk of the sealing of battery assembly, simultaneously because the requirement air channel of forced convertion can take one
The inner space of percentage of batteries system synthesis.
Water-cooling is to be contacted with battery core by water channel to make battery core dispel the heat, but owing to cylindrical battery core only has side permissible
Cooling down, and side is circular, so being linear contact lay with contacting in the plane of water channel, causing heat bridge the least impact heat radiation
Efficiency.
No. 2015108253953 public announcement of a patent application files of China disclose a kind of cylindrical battery water-filled radiator, dissipate
Hot core comprises sub-radiating core, and sub-radiating core is made up of along the short transverse of radiator side by side porous flat pipe, and sub-radiating core is along heat radiation
The width of device forms radiating core side by side, and the part that porous flat pipe contacts with cylindrical battery core is stamped into and battery core laminating
Waveform, the two ends of porous flat pipe pass water bar, the battery core of battery module be placed in sub-radiating core and sub-radiating core and
In the space that two ends water bar surrounds, dispelled the heat by sub-radiating core.Although the porous that have employed " waveform " in the program is flat
Pipe design increases contact area, but still there is the problem that radiating efficiency is low.
Also having a kind of radiating mode is conduction of heat.Heat is delivered to from inside battery by heat conducting and radiating by Heat Conduction Material
The mode of outside batteries completes heat radiation.Authorization Notice No. is that CN204680734U discloses a kind of great Rong with heat abstractor
Amount battery, the cylindrical cell including fixture, being arranged on fixture and being formed between these cylindrical cells
Longitudinal slot and transverse slot, described longitudinal slot and/or transverse slot are inserted with fin, solid on described fin
Surely some pieces of elastic conducting backings it are provided with.The program transfers heat to radiator by fin, elastic conducting backing and completes
Heat radiation.But the fin of this structure, elastic conducting backing are arranged between cylindrical cell, and for fin, bullet
Property conducting strip shape have higher requirements, cause that framework is complicated, manufacture the problems such as difficulty, be unfavorable for promoting the use of.
Summary of the invention
This utility model is the heat dissipation problem solving existing cylindrical battery module, mode purport based on heat conducting and radiating
At the radiator structure providing a kind of cylindrical battery module.
The technical solution adopted in the utility model includes fixed support, be arranged on described fixed support and arranged in parallel
Battery, the bus-bar being integrated in described fixed support, described fixed support is heat-conducting plastic, and defines heat-conducting block structure,
Thus the two-stage of battery is separately fixed in heat-conducting block structure；Described bus-bar is heat carrier, and described heat carrier is embedded in described
In heat-conducting block.
Wherein, being provided with elastomeric layer in the hole coordinated between battery and heat-conducting block, described elastomeric layer makes battery
And between heat-conducting block, form interference fit.
Wherein, also include coldplate, described coldplate be arranged on described cylindrical battery module outside and and institute
The side stating heat-conducting block contacts.
Wherein, thermal conductivity flexible pad it is additionally provided with between described heat-conducting block and described coldplate.
Compared to the prior art, this utility model is owing to using Heat Conduction Material to make the mounting bracket of battery so that battery
Having enough area of dissipations, radiating efficiency is higher；Metal bus-bar within battery bracket is also used for heat conduction, due to self
High-termal conductivity can also control battery bracket overall temperature difference while quickly transmission heat, the concentration of heat will not be produced；
External add-in at battery module has coldplate, improves radiating effect；It is compounded with bullet in the hole that fixed support coordinates with battery
Property material layer so that use interference fit between fixed support and battery, it is ensured that good between battery case and battery bracket
Good transmission of heat by contact；Thermal conductivity flexible pad ensure that the good contact between fixed support and liquid coldplate.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of this utility model；
Fig. 2 is the structural representation of an embodiment of the present utility model.
