Background technology
Along with battery technology development with rapid changepl. never-ending changes and improvements, most electric installations all adopt powered battery or it are served as and are stand-by power supply, make that the application of battery is more extensive, but usually because battery container in order to realize electric insulation between the battery, generally adopts the resin of heat-conductive characteristic difference to make; The heat that described battery of while is produced when discharging and recharging is not in time taken away, and makes that the operating ambient temperature of described battery is too high, even may the battery surface temperature reach more than 80 degrees centigrade.Because battery just can not be full of electricity under hot environment, thus charge-discharge performance decline, and also charge and discharge circulation life reduces.And the key that will address this problem is to adopt heat abstractor efficiently, and the heat that battery produced is discharged substantially.Particularly, the most charging or discharging currents that adopt of electric installation are than macrocell, and can the heat of its generation in time distribute, and directly determined the performance of electric installation, also influences the quality that electric installation provides Terminal Service simultaneously.And the battery heat radiation all is to adopt Aluminum Heat Sink and combination of fans to conduct to add heat loss through convection usually, but heat sink bigger diffusion thermal resistance that has and the uneven characteristic of density of heat flow rate distributed pole on the cross section thereof, make the battery radiating effect be subjected to certain influence, directly limited the raising of battery performance, the technical solution of battery heat radiation efficiently scheme is provided for this reason, seems particularly important.
Heat pipe is as a kind of efficient heat transfer medium that utilizes phase-change heat transfer, it is little to have (one) thermal resistance, thermal transmission coefficient big (its heat transfer property is higher two more than the order of magnitude than copper/aluminum), (2) good isothermal, (3) changeability of density of heat flow rate, (4) good characteristics such as direction of heat flow invertibity, so the more common heat sink radiator of heat-pipe radiator have higher heat-sinking capability with and energy-efficient advantage, be widely used in battery heat radiation field and develop.
The general at present heat-pipe radiator that uses is made up of circular heat pipe, radiating fin and pedestal, perhaps plate-type heat-pipe, Aluminum Heat Sink and substrate are formed, its weak point is that its circular heat pipe or plate-type heat-pipe be connected with substrate with radiating fin or Aluminum Heat Sink is a kind of assembly structure, its contact heat resistance is bigger, be subjected to the influence of manufacture craft simultaneously, make its radiating efficiency be subjected to certain restriction.
Notification number is: CN 20142186Y9, the patent No. is: the Chinese patent of ZL200920302396.X discloses a kind of battery heat abstractor, wherein heat pipe absorbs the heat that battery distributed near battery, described heat transferred is to the fixing radiating fin of the other end of heat pipe, by radiating fin and be installed near the radiating fin fan and heat is dispersed into realizes heat radiation in the air.Its radiating effect in the battery heat abstractor effect significantly better than common Aluminum Heat Sink, but its weak point is: the shared space of one battery heat abstractor is excessive, also needs the thermoelectric cooling heat radiation, obviously power consumption too much, the cost height; Its two heat pipe and battery junction technology disclosure, heat pipe and battery contact heat resistance are bigger, are unfavorable for heat transferred.
Summary of the invention
The purpose of this utility model is to provide a kind of cell apparatus, uses heat pipe as heat dissipation element, and heat pipe and battery contact heat resistance are less, be beneficial to heat transferred, simple in structure, the area of dissipation of unit volume is big, the radiating efficiency height can reduce the battery charging and discharging energy consumption, improves charge and discharge circulation life.
The utility model is achieved through the following technical solutions:
A kind of cell apparatus includes an above flat plate cell and flat thin flat plate, and described flat thin flat plate inside is placed with heat pipe array, and heat radiation working medium is filled in the inner chamber of described heat pipe array; Wherein, described cell apparatus includes the flat thin flat plate more than two, the length of every flat plate cell and Width include first outer surface and second outer surface, and described first outer surface and second outer surface are fitted with the intimate of a flat thin flat plate separately; And between two flat thin flat plates that described first outer surface and second outer surface fit tightly respectively, be provided with radiating fin.
A plurality of cross sections of arranging, described flat thin flat plate inside are polygonal pore pipe.
Described flat thin flat plate includes heat release section and endotherm section, and endotherm section fits tightly the outer surface at flat plate cell.
To sum up, the beneficial effects of the utility model are:
A kind of cell apparatus of the present utility model, because cell apparatus includes the flat thin flat plate more than two, the length of every flat plate cell and Width include first outer surface and second outer surface, and described first outer surface and second outer surface are fitted with the intimate of a flat thin flat plate separately; And between two flat thin flat plates that described first outer surface and second outer surface fit tightly respectively, be provided with radiating fin; A plurality of cross sections of arranging, flat thin flat plate inside are polygonal pore pipe; Flat thin flat plate includes heat release section and endotherm section, and endotherm section fits tightly the outer surface at flat plate cell.A plurality of pore pipes of the inner filling liquid working medium of described flat thin flat plate will form the heat pipe effect, heat is passed to heat radiation working medium in the pipe by heat pipe wall, heat radiation working medium heat absorption back evaporation and boiling, change steam into, steam rises to heat release section under the effect of small pressure reduction, after described heat release section is cooled off, vapor condensation is also outwards emitted the latent heat of vaporization, condensate liquid relies on gravity and capillary force to return endotherm section, so go round and begin again the battery distribute heat is distributed in the surrounding environment, because flat thin flat plate inner pore pipe is evacuated, working medium is very easily evaporated and is seethed with excitement, and heat pipe starts rapidly.A kind of cell apparatus of the present utility model, flat plate cell outer surface and flat thin flat plate intimate are fitted; Contact heat resistance between the two is very little, helps the battery heat and conducts.Use heat pipe as heat dissipation element, heat pipe and battery contact heat resistance are less, are beneficial to heat transferred, and be simple in structure, and the area of dissipation of unit volume is big, and the radiating efficiency height can reduce the battery charging and discharging energy consumption, improves charge and discharge circulation life.
