HEAT MANAGEMENT SYSTEM FOR VEHICLE

摘要

The present invention is provided with the following: a switching part (47) that switches the connection state of a first refrigeration circuit (C1) and an engine refrigeration circuit (40); and a first communication part (48) that causes the engine refrigeration circuit (40) and the first refrigeration circuit (C1) to communicate with each other. The engine refrigeration circuit (40) has the following: a circulation flow path (41) in which a heat medium circulates and flows through an engine pump (42), an engine refrigeration flow path (43a) formed in an engine (43), and an engine radiator (44); and a radiator bypass flow path (45) connected to the circulation flow path (41) so that the heat medium bypasses the engine radiator (44) and circulates. The switching part (47) switches the connection state of the first refrigeration circuit (C1) and the radiator bypass flow path (45).
