The shutter-type three-dimensional efficient spiral fin heat exchanger can not only meet the requirements of large-capacity refrigerator’s heat exchange efficiency, but also can give large-capacity refrigerator more space utilization ratio.
The louver spiral finned tube is used to form a three-dimensional spatial structure through bending and twisting layer structure. Two groups of plane spiral finned tube groups, plane fixed support of tube group, base connecting support and base; The two groups of plane spiral finned tube groups are composed of a multi-layer spatial structure spiral finned tube which is bent and twisted as a whole. The plane spiral finned tube group is composed of a serpentine structure in the same plane and a multi-layer spatial structure spiral finned tube which is bent as a whole. The torsion included angle between the plane spiral finned tube groups is 10 ° - 180 °, and a three-dimensional spatial structure is formed through the torsion layer structure between the groups.
