Description
Technical field
The utility model 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 utility model, by a kind of novel battery mould bases heat transfer structure, achieves even quick heat radiating and the heating of power brick.。
Background technology
At present, power battery of electric vehicle battery cell heating generally use electric heating film, electric heating film programming rate is fast, very easily causes by the temperature of the battery cell heated uneven, excessive temperature differentials, the charge-discharge performance of infringement battery and life-span; And the general air of natural environment or the air after freezing of using of battery heat radiation directly takes away heat by battery cell surface and battery current collecting row, this method is subject to the impact of area of dissipation and coefficient of heat transfer, radiating rate is relatively slower, can not get a desired effect.
Summary of the invention
The purpose of this utility model is to provide a kind of soft-package battery attemperating unit, it is by the air heat in the electric air-conditioning system just inner air channel of power brick or refrigeration, air after heating or refrigeration and battery heat conduction mould bases and battery current collecting arrange positive energy exchange, thus be battery cell heating or cooling, can be realize good power brick heating radiating effect.
The purpose of this utility model is achieved in that 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, this battery mould bases is evenly equipped with mould bases chamber, between adjacent mould bases chamber, is provided with heat conduction fin; In 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.
The support fin strengthening rigidity is also provided with between described adjacent mould bases chamber.
The utility model efficiently solves the too fast battery excessive temperature differentials problem caused of electric heating film heating temperature rise; Battery heat conduction mould bases adopts the aluminum mould bases that conductive coefficient is larger, can solve the slow problem of heat transfer rate 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 in power brick, all battery cells are operated in optimum activity temperature range by the utility model, and can ensure that the temperature difference between battery cell significantly reduces.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
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.
Utility model to be described in further detail by example below in conjunction with accompanying drawing; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
Embodiment
According to Fig. 1-2, the utility model is described in detail.A kind of soft-package battery attemperating unit of the present utility model includes power brick 9, battery cell 2 is fixed with by aluminum production cell heat conduction mould bases 1 in power brick 9, 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 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 outside.
The support fin 12 strengthening rigidity is also provided with between adjacent mould bases chamber.
During use, when power brick temperature is higher than normal working temperature, electric heater 4 work quits work, cold enzyme after compression is passed into A/C evaporator 5 by the outside air-conditioning system of power brick, heat exchange is carried out with circulating air, under the effect of air blast 6, the wind of cold wind after air inlet duct 3, the heat exchange of aluminum production cell heat conduction mould bases 1 enters air channel pressure stabilizing cavity 8, and finally enter air blast 6 through exhaust passage 7 successively and circulate, wind flow route as shown by the arrows in Figure 1; When power brick temperature is lower than normal working temperature, electric heater 4 works, and A/C evaporator 5 quits work, the heat exchange of power brick heating process and power brick temperature-fall period and wind flow sequence consensus, therefore omits.In sum, the purpose of this utility model is achieved.
