Cooling system including dual air routing zones
First Claim
1. A cooling system for a vehicle, said cooling system comprising:
- a hood configured to cover a front portion of the vehicle;
a radiator arranged below the hood;
an air-intake port arranged below a front portion of the hood and configured to introduce cooling wind into a first portion of the radiator;
a cooling fan arranged behind the radiator for drawing wind past a second portion of the radiator; and
a fan shroud extending from an area behind cooling fins of the radiator to an area proximate the cooling fan, said fan shroud defining an air-intake channel for routing wind therethrough,wherein a front end of the hood is formed to extend forwardly beyond an upper portion of the radiator in side view, and to be partly vertically aligned with the cooling fins of the radiator,wherein the fan shroud covers part of the cooling fins at a portion of the radiator in an area where the hood and the cooling fins are vertically aligned with each other, and exposes another part of the cooling fins at another portion of the radiator; and
wherein the fan shroud has a substantially rectangular shape in front view, includes an inner wall surface having a substantially arcuate shape broadened gradually toward the front of the vehicle, and is formed to open toward the front of the vehicle.

Abstract
In a vehicle in which a front end of a hood is formed so as to extend forward from an upper portion of radiator in side view, and to be partly vertically aligned and overlapped with cooling fins of the radiator, in a first area of the radiator where the hood and the cooling fins are vertically aligned and overlapped with each other, the cooling fins are covered with a fan shroud from behind, and in a second area of the radiator where an air-intake port allows traveling wind to pass therethrough during movement of the vehicle, the cooling fins are not covered with the fan shroud, but are exposed to such traveling wind. Such arrangement of the cooling system achieves satisfactory cooling of the vehicle even in a situation in which an air-intake port, for introducing air into the radiator, must be made small.

12. A cooling system in a vehicle, said cooling system comprising:
-
a hood configured to cover a front portion of the vehicle; a radiator arranged below the hood; an air-intake port arranged below a front portion of the hood and configured to introduce cooling wind into a lower portion of the radiator; a cooling fan arranged behind the radiator for drawing wind past an upper portion of the radiator; and a fan shroud extending from an area behind cooling fins of the radiator to an area surrounding the cooling fan, said fan shroud defining an air-intake channel for routing wind therethrough, wherein a front end of the hood is formed to extend forwardly beyond an upper portion of the radiator in side view, and to be partly vertically aligned with the cooling fins of the radiator, wherein the fan shroud covers part of the cooling fins at the upper portion of the radiator in an area where the hood and the cooling fins are vertically aligned with each other, and exposes another part of the cooling fins at the lower portion of the radiator; and wherein the fan shroud has a substantially rectangular shape in front view, includes an inner wall surface having a substantially arcuate shape broadened gradually toward the front of the vehicle, and is formed to open toward the front of the vehicle. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
