Claims

[Scope of utility model registration request]

(1) A plurality of external fans having a burring part in the center are press-fitted and fixed to the outer circumferential surface of the heat exchanger main body, a plurality of protrusions are provided on the flat part of the external fan, and the protrusions are connected to the opposite external part. A heat exchanger installed close to the flat surface of the fan.

(2) The heat exchanger according to claim 1, wherein the burring portions of the external fan are press-fitted so that the burring portions of the external fan face each other with a substantially middle portion of the heat exchanger body as a boundary.
