Title: Blower for radiator
Inventor: KAGEYAMA KIYOSHI
IPC: F01P11/10
Filed: 2001-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a blower 1A for a radiator, allowing a motor 3 to be effectively cooled by forming an air guide 5 on an existing shroud without requiring other cooling members, and giving a long service life to the motor 3. SOLUTION: The blower 1A for the radiator comprises the shroud 2 having an opening portion at one end where a radiator 1 is mounted and the other end where the motor 3 is mounted for driving blower vanes 7. The air guide 5 is formed on the shroud 2 in the state of being directed to the motor 3 so that cooling air is guided from the blower vanes 7 to the air guide 5. Thus, the cooling air generated by the rotation of the blower vanes 7 directly hits the motor 3 through the air guide. The motor 3 is effectively cooled, and so it has improved durability without temperature rise and a longer service life. No other cooling members are required and the construction is simplified in a costwise advantageous manner.
