Abstract

A radiator is provided within an engine room and in front of an engine for cooling engine cooling water. A shutter is provided in front of the radiator and covers a portion of a core surface of the radiator for adjusting an amount of cooling air to be directed toward the radiator. A baffle plate is provided behind a remaining portion of the core surface, which is not covered with the shutter, for directing the air, having passed through the remaining portion, to outside the engine room.

Claims

1. A vehicle engine cooling apparatus comprising:

a radiator disposed within an engine room and in front of an engine for cooling engine cooling water;

a shutter disposed in front of the radiator for adjusting an amount of cooling air to be directed toward the radiator, the shutter being disposed so as to cover a portion of a core surface of the radiator; and

a baffle plate disposed behind a remaining portion of the core surface, which is not covered with the shutter, for directing air, having passed through the remaining portion, to outside the engine room.

2. The vehicle engine cooling apparatus of claim 1, further comprising an outside heat exchanger of a heat-pump type air conditioning device disposed between the shutter and the radiator, wherein an entire core surface of the outside heat exchanger is covered with the shutter.

3. The vehicle engine cooling apparatus of claim 1, further comprising an air cooling heat exchanger disposed in front of the remaining portion of the core surface of the radiator.
