In technique scheme, preferred, the first through hole on the described first fin of some layers starts gradually to the size of dwindling to be applicable to described U-shaped junction away from the described first fin direction of described main body from the described first fin near described main body.Arrange like this, can allow first fin in the first heat abstractor U-shaped junction of fitting, so not only increased heat transfer efficiency, can also make first heat abstractor firmly fix with main body.
In technique scheme, preferred, the second through hole on the described second fin of some layers starts gradually to the size of dwindling to be applicable to described U-shaped junction away from the described second fin direction of described main body from the described second fin near described main body.Arrange like this, can allow second fin in the second heat abstractor U-shaped junction of fitting, so not only increased heat transfer efficiency, can also make second heat abstractor firmly fix with main body.
In technique scheme, preferred, described fixed leg two ends are provided with retainer plate, and described retainer plate is in described first heat abstractor and described second heat abstractor outermost.Arrange like this, can firmly allow fixed leg be fixedly connected with first heat abstractor second heat abstractor and main body by two retainer plates.
Compared with prior art, the beneficial effects of the utility model are: can increase the heat exchanger effectiveness of heat exchanger, especially increase considerably the heat exchanger effectiveness of the exposed U-shaped junction outside fin of heat-exchange tube.
