1. A heat management device for a vehicle, the heat management device comprising:
a battery cooling device configured to cool a battery by using a second heat exchange medium;
an air conditioning device configured to adjust a temperature of an interior of a vehicle by using a third heat exchange medium; and
a second waste heat recovery chiller configured to allow the second heat exchange medium and the third heat exchange medium to exchange heat with each other,
wherein the air conditioning device comprises:
an air conditioning line configured to connect a compressor, a heat dissipation unit, an external heat exchanger, a first expansion valve, and an evaporator;
a branch line connected to the air conditioning line so that the third heat exchange medium bypasses the external heat exchanger; and
valves,
wherein the valves perform control so that the third heat exchange medium flows to the evaporator or the second waste heat recovery chiller through the branch line,
wherein the branch line comprises a first branch line connected to the air conditioning line, a second branch line branching off from the first branch line and disposed to pass through the first waste heat recovery chiller, and a third branch line branching off from the first branch line and disposed to pass through the second waste heat recovery chiller, and
wherein the valves comprise a first 3-way valve disposed at a first branch point P1 at which the air conditioning line and the first branch line meet and a second 3-way valve disposed in the third branch line.
