|1. (WO2017056867) VEHICULAR HEAT MANAGEMENT DEVICE|
TOYOTA JIDOSHA KABUSHIKI KAISHA
|Title:||VEHICULAR HEAT MANAGEMENT DEVICE|
The vehicular heat management device is equipped with a first heat source (21), a second heat source (23), a heater core (24), a first heat medium passage (30), a second heat medium passage (31), a heater core passage (32), switching parts (27, 28), and a control unit (60). The first heat source is disposed on the first heat medium passage, and the second heat source is disposed on the second heat medium passage. The heater core passage forms a flow passage through which the heat medium flows, and on which the heater core is disposed. The switching parts are used for switching of fluid connection/disconnection between the first heat medium passage and the heater core passage, and for switching of fluid connection/disconnection between the second heat medium passage and the heater core passage. The control unit performs switching control and/or second heat source control when the temperature of the heat medium in the heater core passage is equal to or greater than a predetermined temperature. During the switching control, the control unit controls operations of the switching parts such that the second heat medium passage is connected to the heater core passage. During the second heat source control, the control unit causes the second heat source to generate heat.
