(EN) The invention relates to a dual-cycle ambient temperature control device for a battery pack of an electric automobile. The dual-cycle ambient temperature control device comprises a semiconductor refrigerating and heating device, an internal heat exchanger, an internal-circulation infusion pump, an external-circulation infusion pump, a composite heat exchanger, a heat exchanging fan and an electronic control panel, wherein the semiconductor refrigerating and heating device is electrically connected with the electronic control panel, and the internal-circulation infusion pump, the external-circulation infusion pump and the heat exchanging fan are electrically connected with the electronic control panel, separately. The dual-cycle ambient temperature control device is characterized in that aheat exchanger behind the semiconductor refrigerating and heating device, the internal heat exchanger and the internal-circulation infusion pump are communicated with each other via pipelines and connected in series to form a loop; a heat exchanger before the semiconductor refrigerating and heating device, the composite heat exchanger and the external-circulation infusion pump are communicated with each other via pipelines and connected in series to form a loop; so internal and external dual-cycle refrigerant circulation flow channels separated from each other are formed in the same temperature control device. The dual-cycle ambient temperature control device of the invention has the characteristics of simple structure and high work efficiency.
