Description
Technical field
The present invention relates to have the power battery pack of heat sinking function, relate in particular to a kind of phase-change material heat pipe coupling heat-radiation dynamic cell group.
Background technology
Because becoming increasingly conspicuous of problems such as energy shortage and environmental pollution, electric automobile is because of energy-conservation and can reduce the discharging of greenhouse gas and noxious pollutant dust etc. and receive publicity gradually.But electrokinetic cell is in charge and discharge process, inner chemical reaction complexity, especially in large scale and the large current density electric process, inside battery produces a large amount of heat rapidly, the accumulation of heat must cause that battery temperature raises, thereby causes battery performance to descend, in addition leakage may appear, phenomenon such as exit, smolder, battery takes place acutely to burn and blast when serious, influences vehicle performance.Therefore, electrokinetic cell is seriously restricting the development of electric automobile etc.
In recent years, the active demand of electric automobile power battery heat radiation has caused the concern of many electric automobile production firms and battery manufacturers, at present, electrokinetic cell generally all adopts the simplest cooling air mode on the market, and this complex structure, radiating effect are poor.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of phase-change material heat pipe coupling heat-radiation dynamic cell group is provided, it is big compared with prior art to have heat dissipation capacity, the radiating efficiency height, processing is simple, do not increase the intrinsic space of battery pack, can solve the technical problem of electric automobile power battery heat radiation efficiently.
The present invention is achieved through the following technical solutions:
A kind of phase-change material heat pipe coupling heat-radiation dynamic cell group, comprise housing, in housing, be placed with battery pack, described battery pack is made up of a plurality of cells, between cell, be filled with phase-change material in the slit, each adjacent monomer battery closely contacts, and is fitted with heat pipe in the space between each adjacent monomer battery.
Described heat pipe is divided into outer heat pipe and interior heat pipe, and described outer heat pipe is arranged at around the housing, and described interior heat pipe is arranged at the middle part of housing.
The caliber of described outer heat pipe is less than the caliber of interior heat pipe; Described outer heat pipe is identical with the caliber of interior heat pipe.
Described outer heat pipe and interior heat pipe all have evaporation ends and condensation end, and described evaporation ends is installed in the housing, and contact with phase-change material; Described condensation end places the outside of housing; Described evaporation ends and condensation end are respectively arranged with fin or thread groove; Described fin can be integral type or split-type structural.
Beneficial effect compared with prior art of the present invention is: global design of the present invention is simple, intrinsic space when utilizing battery pack to connect, by inserting phase-change material therein, and heat pipe is inserted wherein, coupling by phase-change material and heat pipe, the heat transferred that battery produces, sheds to the outside by condensation end passing to condensation end to evaporation ends.Phase-change material directly contacts with battery, reduces battery and extraneous heat radiation thermal resistance, and phase-change material latent heat is big simultaneously, can adapt to the discharge instantaneous effective buffering of heat of unbalanced heat production of unstable state.
That the present invention has is simple in structure, compact, need not additive decrementation electrokinetic cell electric energy, can satisfy the high efficiency and heat radiation of electric automobile power battery, has potential application foreground.

Embodiment
Below in conjunction with specific embodiment the present invention is done further concrete detailed description the in detail, but embodiments of the present invention are not limited thereto, the technological parameter for not indicating especially can carry out with reference to routine techniques.
Embodiment
As depicted in figs. 1 and 2, phase-change material heat pipe coupling heat-radiation dynamic cell group of the present invention, comprise housing 1, in housing 1, be placed with battery pack, described battery pack is made up of a plurality of cells 2, be filled with phase-change material 3 in the slit between adjacent cell 2, closely contact between each adjacent monomer battery 2, be fitted with many heat pipes in the space between each adjacent monomer battery 2, heat pipe is divided into outer heat pipe 4 and interior heat pipe 5, described outer heat pipe 4 is arranged at around the housing 1, and described interior heat pipe 5 is arranged at the middle part of housing 1.The caliber of described outer heat pipe 4 is less than the caliber of interior heat pipe 5.But outer heat pipe 4 also can be identical with the caliber of interior heat pipe 5.
As shown in Figure 3, above-mentioned outer heat pipe 4 and interior heat pipe 5 all have evaporation ends 9 and condensation end 6, specifically are, evaporation ends 9 is installed in the housing 1, and contacts with phase-change material 3; Described condensation end 6 places the outside of housing 1.For the ease of processing or installation, described fin can be selected integral type or split-type structural for use.Evaporation ends 9 absorbs the battery heat by phase-change material 3, and condensation end 6 stretches out the outer release heat of battery pack.For avoiding heat to reflux, between condensation end 6 and the evaporation ends 9 adiabatic end.For better heat absorption and heat radiation, need to increase heat exchange area, therefore be respectively arranged with fin 6-1,9-1 on the surface of evaporation ends 9 and condensation end 6 or form thread groove on the surface, because the heat production of battery set charge/discharge process is non-linear, therefore, the latent heat of phase-change material 3 had both played the heat cushioning effect, also played the effect of bulk temperature in the balancing battery group.Described fin 6-1,9-1 can adopt sheathed mode to be installed in the end of evaporation ends 9 and condensation end 6.But also can with evaporation ends 9 and condensation end 6 integral structures.
The present invention is need not under the situation that the additive decrementation battery power consumes, by the coupling of phase-change material 3 and heat pipe, with the heat transferred of battery pack heat production to the battery pack external environment condition, to reach the purpose of heat radiation.Specifically be, the heat of battery pack heat production when discharging and recharging stores by the form of phase-change material 3 with latent heat, because phase-change material 3 direct and all cells 2 contact, its contact heat resistance contacts little more than air with battery.The heat that is stored in the phase-change material 3 exports to the battery pack external environment condition by heat pipe 4,5.
Just can realize the present invention preferably as mentioned above.
The foregoing description is a preferred implementation of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
