Cooling device including a solar radiation blocking unit for a vehicle-mounted electrical apparatus

摘要

A cooling device for an electrical apparatus mounted on a rear side of a vehicle having a cooling airflow intake port in the vehicle interior at a lower section of a rear windshield, a supply unit which supplies a cooling airflow through the cooling airflow intake port to the electrical apparatus, a blocking unit for blocking solar radiation from coming onto the cooling airflow intake port through the rear windshield, and a control unit to control the blocking unit based on at least one of intensity of the solar radiation coming onto the cooling airflow intake port and a temperature of the cooling airflow.

主权项

1. A cooling device for an electrical apparatus mounted on a vehicle, the electrical apparatus being mounted at a rear side of the vehicle, the cooling device comprising:
a cooling airflow intake port which is provided in the vehicle interior adjacent to a lower section of a rear windshield; a supply unit which supplies a cooling airflow through said cooling airflow intake port to said electrical apparatus; a blocking unit that is configured to block solar radiation incident on and transmitted through said rear windshield from coming onto said cooling airflow intake port; and a control unit which, if said supply unit supplies the cooling airflow to said electrical apparatus, controls said blocking unit based on at least one of an intensity of the solar radiation coming onto said cooling airflow intake port and a temperature of the cooling airflow.
