Abstract
A vehicle heat management device that includes: a pump that circulates cooling water around a cooling water circulation path; an air blower that blows air through a radiator toward an exterior heat exchanger of an air-conditioning device of a vehicle; and a de-icing controller that, in a case in which an estimated ice adhesion amount on the exterior heat exchanger is a predetermined value or greater, starts first de-icing control by using a pump to circulate cooling water in a flow path including a second flow path, in the state in which a first flow path and the second flow path are isolated from each other by a first switching section, and using the air blower to blow air through the radiator toward the exterior heat exchanger.
Claims14
A vehicle heat management device, comprising:
- a first valve that, in a cooling water circulation path including (i) a first flow path passing a heat generating body of a vehicle and (ii) a second flow path passing a radiator and not passing the heat generating body, is switchable between a state in which the first flow path and the second flow path are in communication with each other and a state in which the first flow path and the second flow path are isolated from each other;
- a pump that circulates cooling water around the cooling water circulation path;
- a fan that blows air through the radiator toward an exterior heat exchanger of an air-conditioning device of the vehicle;
- and
- a processor that is configured to, in a case in which an estimated ice adhesion amount on the exterior heat exchanger is a predetermined value or greater, start first de-icing control by (i) using the pump to circulate cooling water in a flow path including the second flow path in the state in which the first flow path and the second flow path are isolated from each other by the first valve and (ii) using the fan to blow air through the radiator toward the exterior heat exchanger.
A non-transitory recording medium storing a program to cause a computer to execute processing, the processing comprising:
- in a case in which an estimated ice adhesion amount on an exterior heat exchanger of an air-conditioning device of a vehicle is a predetermined value or greater, in a cooling water circulation path including a first flow path passing a heat generating body of a vehicle and a second flow path passing a radiator and not passing the heat generating body, starting first de-icing control by:
- (i) using a pump that circulates cooling water around the cooling water circulation path to circulate cooling water in a flow path including the second flow path in a state in which the first flow path and the second flow path are isolated from each other by a first valve that is switchable between a state in which the first flow path and the second flow path are in communication with each other and the state in which the first flow path and the second flow path are isolated from each other, and
- (ii) using a fan to blow air through the radiator toward the exterior heat exchanger.
