The present invention relates to an integrated heat management circuit for a vehicle, which comprises: a battery line which is connected so that cooling water flowing inside can exchange heat with a high-voltage battery, and which includes a first pump and a first radiator for circulating the cooling water inside; a water heater placed at a downstream point of the first pump on the battery line to heat the cooling water in the battery line; a refrigerant line in which a refrigerant flows inside, and which includes an external air condenser which is able to exchange heat with the external air, and a cooling core for an indoor air conditioning placed in an indoor air conditioning line; a chiller which is connected to bypass the first radiator in the battery line, connected to bypass the cooling core for indoors air conditioning in the refrigerant line, and connected so that the cooling water in the battery line can exchange heat with the refrigerant in the refrigerant line; and a control valve which controls the flow of the cooling water so that the cooling water flowing to the battery line can pass through the chiller or the first radiator. The present invention aims to provide an integrated heat management circuit for a vehicle, which is able to selectively recover waste heat of electronics parts and high-voltage batteries by using a single chiller.
