Abstract
A heat management device may include: a first heat circuit; a second heat circuit; a heat exchanger configured to cool the first heat circuit and heat the second heat circuit; air-heating apparatus configured to heat air using the second heat circuit; a battery and electrical apparatus configured to be cooled by the first heat circuit; and a radiator configured to exchange heat between the first heat circuit and outside air. A controller may be configured, in the second process, to cause the heat exchanger to cool the heat exchanger passage while a heat medium circulates in the heat exchanger passage and the battery passage and bypasses the radiator passage. The controller may be configured, in the third process, to cause the radiator to cool the heat medium while the heat medium circulates in the radiator passage and the electrical apparatus passage and bypasses the heat exchanger passage.
