To provide a vehicular temperature management device capable of suppressing power consumption following to size increase of a pump for circulating a coolant and pump driving.SOLUTION: A vehicular temperature management device comprises: a channel selection part for selecting at least one of a chiller heat exchange channel, a radiator heat exchange channel, and a heater heat exchange channel, as a channel of a coolant in a coolant circulation circuit; a switching control part for controlling the channel switching part so as to select at least one of the chiller heat exchange channel, the radiator heat exchange channel, the heater heat exchange channel; and an actuation control part for controlling actuation of the chiller. The switching control part controls the channel selection part to select the chiller heat exchange channel, when selecting as the channel for a coolant, the radiator heat exchange channel or the heater heat exchange channel, and the actuation control part does not actuate the chiller.SELECTED DRAWING: Figure 1
