Spiral fin heat exchanger with a new fixed manner

Abstract

A spiral fin heat exchanger with a new fixed manner includes a bended fin tube comprising a inner tube on which fins are provided, and several fixing members are provided on the fin tube, the fixing member includes an upper bracket and a lower bracket, and the upper bracket comprises a cover plate and a vertical plate, the upper bracket is fixedly connected with the lower bracket, and the fins on the fin tube are caught between the cover plate and the lower bracket, a positioning groove is provided on the vertical plate, and the inner tube of the fin tube is caught in the positioning groove. The spiral fin heat exchanger can fix the fins and the inner tube of the fin tube simultaneously through the upper and lower brackets of the fixing member, thereby achieving the effect of dual fixation, such that the fin tube can be fixed more firmly and is not easy to loosen, which can in turn reduce the noise of spiral fin heat exchanger effectively.

1 . A spiral fin heat exchanger with a new fixed manner including a bended fin tube comprising a inner tube on which fins are provided, it is characterized in that: several fixing members are provided on the fin tube, the fixing member includes an upper bracket and a lower bracket, the upper bracket comprises a cover plate and a vertical plate, the upper bracket is fixedly connected with the lower bracket, and the fins on the fin tube are caught between the cover plate and the lower bracket, a positioning groove is provided on the vertical plate, and the inner tube of the fin tube is caught in the positioning groove. 
     
     
         2 . The spiral fin heat exchanger with a new fixed manner according to  claim 1 , characterized in that: the fin tube is repeatedly bended, and lengths of the two adjacent bends of the fin tube are different. 
     
     
         3 . The spiral fin heat exchanger with a new fixed manner according to  claim 1 , characterized in that: the upper bracket is fixedly connected with the lower bracket through a side bracket.
