Description
Technical field
The present invention relates to a kind of cooling device for battery pack, more particularly to battery bag heat conducting and heat radiating device.
Background technology
Battery bag is the Large Copacity electric energy storage device that electricity is provided for electron product, and battery bag can dissipate in charging process
Send out heat substantial amounts of, it is therefore desirable to cooling device is installed cooling down operation is carried out to battery bag, prevent battery bag temperature is too high from causing
Situations such as battery bag is burst, the current type of cooling is mostly to contact cooling tube with battery cooling system：Chinese patent
201210356943.9 disclosing battery cooling system, it includes：Battery；Two battery cooling tubes, are longitudinally arranged at battery
And it is parallel to each other at a certain distance each other；And clamping element, battery cooling tube is forced against battery module, to be thermally contacted,
Although but such a setting light structure, do not need with cooling tube contact side in the middle part of battery bag first by heat reach both sides again with it is cold
But pipe carries out heat exchange operation so that such a cooling system cooling effectiveness is low, it is impossible to carry out samming cooling, another type of cooling
For monoblock coldplate is fitted completely with battery bag side, though such a mode can improve cooling effectiveness, plate structure of cooling is heavy,
Thickness is big, adds battery bag radiating cost, while the occupancy volume of battery bag heat abstractor is added, it is very inconvenient.
The content of the invention
Present invention solves the technical problem that being to provide a kind of simple in construction, lightweight battery bag heat conducting and heat radiating device.
The technical solution adopted for the present invention to solve the technical problems is：Battery bag heat conducting and heat radiating device, including battery sheet
Body, in addition to heat-conduction even temperature plate, battery body surface are fitted with heat-conduction even temperature plate bottom, and battery sheet is stretched out on heat-conduction even temperature plate top
Body, the outside batteries are additionally provided with the shell that heat-conduction even temperature plate is fitted with battery body fixation, heat-conduction even temperature plate top one
Side is provided with cooled plate, and cooled plate port is provided with liquid inflow port and liquid flowing outlet.
It is further：Thermal interfacial material is provided between battery body and the heat-conduction even temperature plate.
It is further：The heat-conduction even temperature plate and cooled plate are provided with two pieces, two blocks of heat-conduction even temperature plates and water
Cold drawing is separately positioned on battery bag both sides.
The beneficial effects of the invention are as follows：The present invention is combined heat-conduction even temperature plate with cooled plate, due to the thickness of heat-conduction even temperature plate
Degree is in 3mm or so, and cooled plate need to only use simple two channel water-coolings plate, and heat passes to water cooling by heat-conduction even temperature plate
Plate carries out heat discharging operation, so as to reduce the setting of cooled plate while the effect of temperature uniforming heat radiation can be reached so that present apparatus structure
Simply, it is lightweight while radiating effect is high, it is easy to the modularization of battery modules.

Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Battery bag heat conducting and heat radiating device as shown in Figure 1, battery bag heat conducting and heat radiating device, including battery body 1, in addition to
Heat-conduction even temperature plate 2, the surface of battery body 1 is fitted with the bottom of heat-conduction even temperature plate 2, and battery body 1 is stretched out on the top of heat-conduction even temperature plate 2,
The outside batteries, which are additionally provided with to offer on the shell 5 fixed heat-conduction even temperature plate 2 and battery body 1 and fitted, shell, to be used for
The circular hole of radiating, the shell is integral type structure, and the shell carries out semi-surrounding, heat conduction to heat-conduction even temperature plate and battery body
The top side of temperature-uniforming plate 2 is provided with cooled plate 3, and the port of cooled plate 3 is provided with liquid inflow port 6 and liquid flowing outlet 7, coolant
The influent inflow entrance 6 from from outside pipeline, is flowed out after flowing through the inside of cooled plate 3 through liquid flowing outlet 7, and work is carried out in battery bag
When making, battery bag distributes amount of heat, and heat is by the lower absorbent of heat-conduction even temperature plate 2 to top and passes to cooled plate 3, due to
Cooled plate 3 is connected by liquid inflow port 6 and liquid flowing outlet 7 with circulating water line, and water, which flows through cooled plate 3, takes away heat,
It is achieved thereby that the cooling to battery, due to the setting of heat-conduction even temperature plate 2 so that the water cooling set of being fitted with heat-conduction even temperature plate 2
Plate 3 need to select simple two channel water-coolings plate 3, and two channel water-cooling plates 3 are that the radiating that can be achieved to battery bag entire surface is grasped
Make, because the thickness of temperature-uniforming plate only has 3mm or so, thickness is significantly thinner than cooled plate 3, therefore such a structure setting is compared to will be whole
Block cooled plate 3 is simply compact with battery bag bonding structure, lightweight, takes small volume, and heat transfer efficiency is high, it is easy to battery modules
Heat-conduction even temperature plate 2 and battery bag can be brought into close contact by modularization, the setting of shell 5, the heat-conduction even temperature plate 2 and cooled plate 3
Fixation bolt can be used to fix or fixed with clip.
On the basis of the above, thermal interfacial material 4, the hot boundary are provided between the battery body 1 and heat-conduction even temperature plate 2
Facestock material can be：Heat-conducting pad, silicagel pad etc..The thermal interfacial material 4 be used to filling up battery body 1 and heat-conduction even temperature plate 2 it
Between space, it is ensured that battery body 1 can radiate in time, increase its heat dispersion.
On the basis of the above, the heat-conduction even temperature plate 2 and cooled plate 3 are provided with two pieces, two blocks of heat-conduction even temperature plates 2
Battery bag both sides are separately positioned on cooled plate 3, such a setting can simultaneously be radiated in battery bag both sides, strengthen radiating effect
Rate, it is ensured that the steady operation of battery bag.
Particular embodiments described above, has been carried out further in detail to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail it is bright, should be understood that the foregoing is only the present invention specific embodiment, be not intended to limit the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements done etc., should be included in the guarantor of the present invention
Within the scope of shield.
