Abstract
An HV_ECU executes a program including: switching, if an operation is in an A/C intake mode and absolute value of temperature difference Thi−Tlo is larger than a predetermined value A and temperature Thi is smaller than a predetermined value B, the operation mode to a compartment intake mode; switching, if the operation is in the compartment intake mode, the compartment intake mode is requested to prevent increase in temperature difference, the absolute value of temperature difference Thi−Tlo is larger than a predetermined value A and temperature Thi is equal to or larger than the predetermined value B, the operation mode to an A/C intake mode; and executing a normal intake mode switching control.

25. A cooling apparatus for electrical equipment including a plurality of components, comprising:
-
a medium passage including a first end connected to an inlet and a second end connected to said electrical equipment, and including a plurality of cooling medium distribution routes between said inlet and said electrical equipment; a supply unit supplying the cooling medium through said medium passage to said electrical equipment; a detecting unit detecting temperature difference between at least two components on upstream and downstream sides of said cooling medium among said plurality of components; and a selecting unit selecting any one of said plurality of routes;
whereinsaid selecting unit selects, when absolute value of said detected temperature difference exceeds a predetermined value, a route that makes smaller absolute value of temperature difference between said cooling medium and either one of said two components, from among said plurality of distribution routes. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
