Claims

[Scope of utility model registration request]

A movable piece having an air enclosing structure is interposed between each fin of a large number of heat dissipation fins arranged in parallel at a predetermined interval in the heat generating part of the heat generating element, and this movable piece is rotated or swung to create space between the heat dissipation fins. Send cold air,
A radiator characterized in that warm air between the radiating fins is discharged.
