Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
In order to realize the heat radiation of battery, under the fail safe that ensures vehicle, use as much as possible again the energy of power brick, improve the efficiency of electric energy, the utility model embodiment provides a kind of power brick heat abstractor for electric automobile, referring to Fig. 1, described below:
This power brick heat abstractor comprises: the closed loop being made up of the first entrance 8, first passage 9, second channel 10, power brick 3 and third channel 11, also comprises: be respectively arranged with the first temperature sensor 5 and the second temperature sensor 6 at the first entrance 8, crew module 1 place; Between crew module 1 and the second entrance 12, be provided with unidirectional valve 2, between the first entrance 8 and first passage 9, be provided with condenser 4; Unidirectional valve 2, power brick 3, condenser 4, the first temperature sensor 5 and the second temperature sensor 6 are electrically connected respectively entire car controller 7; The first temperature sensor 5 gathers the temperature at the first entrance 8 places, and the second temperature sensor 6 gathers the temperature in crew module 1;
Temperature signal in the real-time transmission bag of power brick 3 is to entire car controller 7, and when the temperature in power brick 3 reaches temperature peak, entire car controller 7 is controlled condenser 4 and started; The air themperature at the first entrance 8 places is first threshold, and temperature in power brick 3 is in working range time, and entire car controller 7 is controlled condenser 4 and closed; When the temperature that the second temperature sensor 6 collects is Second Threshold, entire car controller 7 is controlled unidirectional valve 2 and is opened; The temperature that the second temperature sensor 6 detects is during higher than the value of the first temperature sensor 5, or the temperature that detects of the second temperature sensor 6 is while reaching the 3rd threshold value, and entire car controller 7 is controlled closing of unidirectional valve 2.
When practical application, the model of entire car controller 7 can be: the XC2765 of company of Infineon; The model of the first temperature sensor 5, the second temperature sensor 6 can be: the VT2K252GB90C3435B-L25T5D5 of exsense product; The model of condenser 4 can be: HBS-P0260; The model of unidirectional valve 2 can be: SCV1602DVL, when specific implementation, according to carrying out the selection of model in practical application, the utility model embodiment does not limit this.
