Title:
HEAT EXCHANGING DEVICE
Document Type and Number:
Japanese Patent JP2005147428
Kind Code:
A
Abstract:
To efficiently clean dust attached to a heat exchanger.
A nozzle 21 is mounted in a shroud 16 mounted between a cooling fan 12 and a radiator 13 vertically movable along a heat radiating part 13A of a radiator 13, and a compressed air is injected toward the heat radiating part 13A of the radiator 13 from an injection hole 23 of the nozzle 21. As the compressed air from the nozzle 21 can be intensively injected to the dust 35 attached to the heat radiating part 13A while vertically moving the nozzle 21 along the heat radiating part 13A of the radiator 13, the dust 35 can be surely eliminated.
