Abstract
The invention relates to a soft package battery temperature control apparatus, which comprises a battery package, and is characterized in that a battery monomer is fixed in the battery package through a battery heat conduction die holder, the die holder chambers are uniformly distributed on the battery die holder, a heat conduction fin is arranged between the adjacent die holder chambers; an air inlet duct is communicated to one side of the battery package, and an air outlet duct is communicated to the opposite side, and a blower, an air-conditioning evaporator and an electric heater are connected to the air inlet duct and the air outlet duct in series outside the battery package. The temperature control apparatus can effectively solves the problem of oversize temperature difference of the battery due to overquick heating and temperature increasing of an electric heating membrane; the battery heat conduction die holder employs an aluminum molding rack with large heat conduction coefficient, on one hand, the problem of slow heat exchange speed can be solved; on the other hand, the aluminum molding rack intensity is greater than that of a plastic molding rack, so that structure size is reduced, space contradiction of the entire battery package is solved, a lightweighting design idea of the battery package is completely accorded. The temperature control apparatus can ensure operation of all the cell monomers in the battery package in an optimum active temperature scope, and can ensure the great reduction of temperature difference between battery monomers.
Description
Technical field
The invention belongs to electric vehicle engineering field, specifically a kind of heat management system of novel electric automobile power battery, be specially adapted to the heat management of rectangle flexible-packed battery monomer composition power brick, the present invention, by a kind of novel battery mould bases heat transfer structure, has realized even quick heat radiating and the heating of power brick.
Background technology
At present, power battery of electric vehicle the general electric heating film that uses of battery cell heating, electric heating film programming rate is fast, very easily causes the temperature inequality of heated battery cell, excessive temperature differentials, charge-discharge performance and the life-span of infringement battery; And air after general air or the refrigeration that uses natural environment of battery heat radiation is directly arranged by battery cell surface and battery current collecting and is taken away heat, this method is subject to the impact of area of dissipation and coefficient of heat transfer, radiating rate is slower, can not get a desired effect.
Summary of the invention
The object of this invention is to provide a kind of soft-package battery attemperating unit, it is by just air heat or the refrigeration in the inner air channel of power brick of electric air-conditioning system, air after heating or refrigeration and battery heat conduction mould bases and battery current collecting row positive energy exchange, thereby being battery cell heating or cooling, can be to realize good power brick heating radiating effect.
The object of the present invention is achieved like this: this soft-package battery attemperating unit includes power brick, it is characterized in that: in power brick, be fixed with battery cell by battery heat conduction mould bases, on this battery mould bases, be evenly equipped with mould bases chamber, between adjacent mould bases chamber, be provided with heat conduction fin; In a side UNICOM air inlet duct, the opposite side UNICOM exhaust passage of power brick, this air inlet duct and exhaust passage are serially connected with air blast, A/C evaporator and electric heater in power brick outside.
Between described adjacent mould bases chamber, be also provided with the support fin that strengthens rigidity.
The present invention efficiently solves the too fast battery excessive temperature differentials problem causing of electric heating film heating temperature rise; Battery heat conduction mould bases adopts the larger aluminum mould bases of conductive coefficient, can solve the problem that heat transfer rate is slow on the one hand; Aluminum mould bases intensity is greater than plastics mould bases on the other hand, can reduce physical dimension, solves the space contradiction of power brick entirety, and meets the light-weight design theory of power brick completely.Can ensure that by the present invention in power brick, all battery cells are operated in optimum activity temperature range, and can ensure that the temperature difference between battery cell significantly reduces.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structure for amplifying schematic diagram of the battery heat conduction mould bases in Fig. 1.
The symbol description of accompanying drawing major part: 1 aluminum production cell heat conduction mould bases, 2 battery cells, 3 air inlet ducts, 4 electric heaters, 5 A/C evaporators, 6 air blasts, 7 exhaust passages, 8 air channel pressure stabilizing cavities, 9 power brick, 10 mould bases chambeies, 11 heat conduction fins, 12 support fin.
Below in conjunction with accompanying drawing and by example, invention is described in further detail, but following example is only the present invention's example wherein, does not represent the rights protection scope that the present invention limits, the scope of the present invention is as the criterion with claim.
Embodiment
Describe the present invention according to Fig. 1-2.A kind of soft-package battery attemperating unit of the present invention includes power brick 9, in power brick 9, is fixed with battery cell 2 by aluminum production cell heat conduction mould bases 1, on this aluminum production cell mould bases 1, is evenly equipped with mould bases chamber 10, between adjacent mould bases chamber, is provided with heat conduction fin 11; In a side UNICOM air inlet duct 3, the opposite side UNICOM exhaust passage 7 of power brick 9, this air inlet duct 3 and exhaust passage 7 are serially connected with air blast 6, A/C evaporator 5 and electric heater 4 in power brick 9 outsides.
Between adjacent mould bases chamber, be also provided with the support fin 12 that strengthens rigidity.
When use, when power brick temperature is during higher than normal working temperature, electric heater 4 work quit work, the cold enzyme after compression is passed into A/C evaporator 5 by the outside air-conditioning system of power brick, carry out heat exchange with circulating air, under the effect of air blast 6, the wind of cold wind after air inlet duct 3,1 heat exchange of aluminum production cell heat conduction mould bases enters air channel pressure stabilizing cavity 8, finally enters air blast 6 through exhaust passage 7 successively and circulates, and wind flow route as shown by the arrows in Figure 1; When power brick temperature is during lower than normal working temperature, electric heater 4 is worked, and A/C evaporator 5 quits work, and the heat exchange of power brick heating process and power brick temperature-fall period and wind flow sequence consensus, therefore omit.In sum, realized object of the present invention.
