Cooling unit
First Claim
1. A cooling unit for generating air for cooling a core of a heat exchanger, comprising:
- a motor;
a driving shaft extending from the motor, the driving shaft to be disposed parallel to the core;
a first fan to be opposed to the core for generating the air for cooling the core, the first fan having a first rotation shaft connected to the driving shaft through a gear to be rotated by the driving shaft;
a fan shroud supporting the first fan and configured to conduct the air from the core toward the first fan; and
a second fan having a second rotation shaft and configured to generate air for cooling the motor, whereinthe second rotation shaft is disposed coaxial with the driving shaft and rotatable with the driving shaft such that the second fan is rotated by the driving shaft when the first fan is rotated.

Abstract
A cooling unit includes a motor, a driving shaft, a first fan, a second fan, and a fan shroud. The driving shaft extends from the motor and is disposed parallel to a core of a heat exchanger. The first fan is disposed to oppose the core for generating air for cooling the core. The first fan has a first rotation shaft connected to the driving shaft through a gear such that the first fan is rotated by the driving shaft. The fan shroud is configured to support the first fan and conduct the air from the core to the first fan. The second fan has a second rotation shaft disposed coaxial with the driving shaft and rotatable with the driving shaft. The second fan is rotated by the driving shaft when the first fan is rotated, thereby to supply the motor with air for cooling the motor.
