The below describes embodiments of the invention in detail, and the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the present invention, and can not be interpreted as limitation of the present invention.
The hot junction of the radiating tube described in the present invention refers to the end away from the radiating tube colling end, and this end is inserted in the insulating heat-conductive plate; The cold junction of described heating tube refers to the end away from the heating tube fire end, and this end is inserted in the insulating heat-conductive plate.
Be illustrated in figure 1 as the electric automobile power battery temperature control module in the present embodiment, formed by radiator 1, power brick 2, the cuboid cell 7, insulating heat-conductive plate 3, heating tube 4 and the radiating tubes 6 that are arranged in parallel in the power brick 2.Insulating heat-conductive plate 3 is arranged in every cell 7 two sides, with the side close contact of battery, is an insulating heat-conductive plate between two adjacent cells, and also respectively arranges an insulating heat-conductive plate 3 in cell 7 outsides at two ends; At the center of each insulating heat-conductive plate 3 horizontal through hole is set, this through hole is parallel to the side of cell.
In the horizontal through hole of each adjacent insulating heat-conductive plate 3, insert successively heating tube 4 and radiating tube 6, specifically, every is provided with a horizontal through hole in all insulating heat-conductive plates, insert heating tube in the through hole therein after, with inserting radiating tube in the adjacent through hole of this through hole; And insert the cold junction 4a of heating tube and the hot junction 6b of radiating tube in the horizontal through hole fully, the fire end 4b of heating tube and the colling end 6a of radiating tube place power brick 2 outsides, in the present embodiment, the fire end 4b of all heating tubes places the same side of power brick 2, and the colling end 6a of all radiating tubes places the opposite side of power brick 2.Fire end 4b at each heating tube is provided with heater 5, and described heater can be that to twine electrical heating wire or the electric heating sleeve is set also can be that other can realize the element that heats; The colling end 6a insertion of each radiating tube is arranged in the radiator 1 in power brick 2 outsides, as shown in Figure 4.
As shown in Figures 2 and 3, in the present embodiment, in order to reduce the cost of manufacture of battery temperature control module, the heating tube 4 and the radiating tube 6 that use are gravity assisted heat pipe, its common trait is that all the height than the hot junction 6b of the fire end 4b of heating tube and radiating tube is low for the colling end 6a of the cold junction 4a of heating tube and radiating tube, the cold junction 4a that is heating tube is lower than the fire end 4b of heating tube, and the colling end 6a of radiating tube is lower than the hot junction 6b of radiating tube.
In the electric automobile power battery that is comprised of battery temperature control module of the present invention, battery temperature control module is arranged in pairs in opposite directions, described radiator 1 is concentrated arranged together, forms radiator panel, in radiator panel one side blower fan 8 is set.In the present embodiment, adopt 4 Battery pack temperature control modules to arrange in pairs, as shown in Figure 5.
Operation principle of the present invention is as follows:
As shown in Figure 2, in charging electric vehicle, perhaps when electric automobile starts, when cell 7 temperature are lower than the uniform temperature level, temperature can be set, in the present embodiment, when being lower than 0 ℃, place the heater 5 startup work of heating tube fire end 4b, the fire end 4b of heating tube is heated the vaporization so that the liquid medium among the fire end 4b of heating tube is heated, become the cold junction 4a that gaseous medium rises to heating tube, and after the cold junction 4a of heating tube condensation with thermal release to insulating heat-conductive plate 3, self is the liquefy medium again, relies on self gravitation to be back to the fire end 4b of heating tube.So repeatedly, constantly with the heat transferred insulating heat-conductive plate 3 of heater 5.Absolutely insulating heat-conductive plate 3 constantly passes to cell 7 with its close contact by heat conduction with heat again, thereby cell 7 is heated, and its temperature levels is risen.When cell 7 temperature reach proper level, in the present embodiment, when this value is higher than 10 ℃, can close heater 5 stopped heatings.
As shown in Figure 3, in the electric automobile during traveling process, because the heating meeting of cell 7 so that its temperature constantly raise, when the temperature of cell 7 surpasses the work threshold values of radiating tube 6, be set as 40 ℃ in the present embodiment, can be set as other temperature in other embodiments, radiating tube 6 namely starts starts working, and blower fan 8 starts simultaneously.Be that cell 7 is by the hot junction 6b of insulating heat-conductive plate 3 with the heat transferred radiating tube of cell 7, so that the vaporization of the liquid medium among the hot junction 6b of radiating tube, become the colling end 6a that gaseous medium rises to radiating tube, and after the colling end 4a of radiating tube condensation, thermal release is fixed on the radiator 1 of power brick 2 outer walls, 8 pairs of radiators of blower fan 1 by the outside carry out air blast cooling, so that heat is constantly taken away; Meanwhile, the gaseous medium again liquefy medium that is cooled relies on self gravitation to be back to the hot junction 6b of radiating tube again.So repeatedly, the radiator 1 of the heat transferred outside that constantly cell 7 is produced is also taken away, until the temperature of the hot junction 6b of radiating tube is lower than the work threshold values of radiating tube 6.
In the present embodiment, heating tube is identical with medium in the radiating tube; In other embodiments, heating tube can be not identical with medium in the radiating tube, and such media variations does not affect technical scheme of the present invention.
The present invention can by the fire end 4b heating to heating tube, realize the heating to cell 7 simultaneously by the heating tube 4 of being separated by in twos and radiating tube 6 under low temperature environment; The heat radiation that realizes cell 7 by radiating tube 6 under the Vehicle Driving Cycle high-temperature condition has realized the heat radiation of new-energy automobile power battery group, the integrated structure design that heats, and has overcome the unicity of heat sinking function in the existing power battery pack heat management design.
Simultaneously, because the operation principle of heat pipe is to rely on the vaporization and the liquefaction that are bordering on the medium under the same pressure to carry out heat transfer, so that the two ends temperature of heat pipe is close, it is the temperature uniform properties of heat pipe, so that no matter be heating process or heat radiation process, the each several part temperature of cell 7 is all close, has a narrow range of temperature, effectively avoided having improved its usage economy of electric automobile power battery because the electrokinetic cell that the inhomogeneities of cell 7 temperature causes significantly reduces useful life.
In addition, the present invention arranges battery temperature control module in pairs in opposite directions, make described radiator 1 concentrate arranged together, form radiator panel, in radiator panel one side 8 pairs of radiator panels of blower fan are set and concentrate and to dispel the heat, effectively reduced the blower fan flow resistance in the conventional electric automobile power battery group heat management, reduced fan pressure head, correspondingly greatly reduce blower fan power consumption and fan noise, significantly promoted vehicle performance.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
