Fastening structure of heat radiator and fan

The utility model relates to a packing structure of a radiator and a fan, which comprises an exhaust fan that forms through holes with the outer border of an air-inlet end and enables the tail end of the radiator fin adjacent to the air-inlet end of the exhaust fan, forming a gap at the side edge of the exhausting fins corresponding to the through hole, as well as comprising a plurality of separable packing pieces which comprises packing wear and a packing fixture block; when used, the packing wear is penetrating fixed in the through hole of the exhaust fan, and pushes and fixes the packing fixture block among the exhausting fins, then fastening the mutually corresponding packing pieces by a simple racking action so as to save operating time, when the packing pieces are made of elastic materials, even by the touching cooperation of the packing pieces go provide an shock absorbing and cushioning effect so as to decrease the unnecessary noises when the fan operates.
