Thermal management device for the batteries of an electric or hybrid motor vehicle

摘要

Thermal management device (1) for batteries of an electric or hybrid motor vehicle, said thermal management device (1) comprising a first circulation loop (A) of a refrigerant fluid as well as a second circulation loop (B ) of a heat transfer fluid, said thermal management device (1) also comprising a first (101) and a second (102) two-fluid heat exchanger arranged jointly on both the first (A) and the second (B) loop circulation, said first circulation loop (A) comprising, in the direction of circulation of the refrigerant fluid, a compressor (13), the first dual-fluid heat exchanger (101), the second dual-fluid heat exchanger (102), a first device expansion valve (15) and a first heat exchanger (17) configured to exchange heat energy directly or indirectly with the batteries, the second circulation loop (B) comprising a pump (23), a second heat exchanger their (27) configured to exchange heat energy with an external air flow (F1) and the second (102) and first (101) two-fluid heat exchangers both arranged downstream of the second heat exchanger (27) in the direction of circulation of the heat transfer fluid.
