Description
Technical field
The utility model relates to a kind of equalizing resistance cooling system of new-energy automobile.
Background technology
In the battery management system of new-energy automobile, power brick is an indispensable assembly, and it is to be made up of multiple battery core connection in series-parallel.For the life-span of battery maintenance bag, generally need to do battery core equilibrium treatment, with the voltage that ensures each battery core in consistent state.Battery balanced scheme generally has active equilibrium and passive type equilibrium, and what in current most of new-energy automobile, all adopt is passive type equalization scheme, adopts the mode of resistance consumption power to carry out equilibrium.In passive type equalization process, resistance is because consumed power is generated heat, and especially, in the many battery management systems of series connection battery core, caloric value is larger, can badly influence operational environment and the stability of a system of whole battery management system.
Utility model content
The purpose of this utility model is to provide a kind of equalizing resistance cooling system of new-energy automobile, to overcome prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of equalizing resistance cooling system of new-energy automobile, comprise metal shell, described metal shell below is provided with insulating heat-conductive silicagel pad, and described insulating heat-conductive silicagel pad below is provided with circuit board and described circuit board upper surface is connected with some equalizing resistances of evenly arranging; Described metal shell, insulating heat-conductive silicagel pad and circuit board are parallel to each other.
Further, described metal shell and insulating heat-conductive silicagel pad closely attach.
Further, described insulating heat-conductive silicagel pad and equalizing resistance closely attach.
The beneficial effects of the utility model are: can effectively reduce by the equalizing resistance temperature rise causing of generating heat, reduce the ambient temperature of battery management system work, thereby protection device and system be avoided the inefficacy causing due to high temperature.

Embodiment
As shown in Figure 1-2, the equalizing resistance cooling system of a kind of new-energy automobile described in the utility model embodiment, comprise metal shell 1, described metal shell 1 below is provided with insulating heat-conductive silicagel pad 2, and described insulating heat-conductive silicagel pad 2 belows are provided with circuit board 4 and described circuit board 4 upper surfaces are connected with some equalizing resistances of evenly arranging 3; Described metal shell 1, insulating heat-conductive silicagel pad 2 and circuit board 4 are parallel to each other.Described metal shell 1 closely attaches with insulating heat-conductive silicagel pad 2.Described insulating heat-conductive silicagel pad 2 closely attaches with equalizing resistance 3.
When concrete application: the equalizing resistance cooling system of the new-energy automobile described in the utility model embodiment is the complete structure after circuit board 4 is installed, and described insulating heat-conductive silicagel pad 2 is to be filled between metal shell 1 and circuit board 4 in the time that circuit board 4 is installed.
The radiating principle of the equalizing resistance cooling system of the new-energy automobile described in the utility model embodiment is: when equalizing resistance 3 adstante febres, its caloric value is except small part is by circuit board 4 heat radiations, most of heat passes to metal shell 1 by insulating heat-conductive silicagel pad 2, and metal shell 1 is delivered to heat in air again.Like this temperature of equalizing resistance 3 just not can due to consumed power rise too high, affect system works.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
