Thermal management device for an electric or hybrid motor vehicle

摘要

The present invention relates to a thermal management device comprising an indirect air conditioning circuit (1) for a motor vehicle comprising: - a first refrigerant fluid loop (A) comprising a compressor (3), a bifluid heat exchanger (5), a first expansion device (7), an evaporator (9), a second expansion device (11), an evapo / condenser (13), and * a first bypass line (30) comprising a first shut-off valve (33 ), * a first internal heat exchanger (19), * a second internal heat exchanger (19 '), * a second bypass pipe (40) comprising a third expansion device (17) arranged upstream of a cooler (15), * a bypass branch (80) comprising a first external radiator (84), - a second heat transfer fluid loop (B) in which a heat transfer fluid is intended to circulate, the bifluid heat exchanger (5) being arranged jointly on the one hand on the first goat the refrigerant (A) downstream of the compressor (3), between said compressor (3) and the first expansion device (7), and on the other hand on the second heat transfer fluid loop (B).
