Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a buffer type spiral finned tube, which comprises a tubular body 1, a plurality of outer fins 2 uniformly connected to the periphery of the body 1, a plurality of inner fins 3 connected to the inside of the body 1, a first tube ring 4 and a second tube ring 5 respectively connected to the two ends of the body 1, and a detachable filter screen 6 connected to the inside of one end of the body 1.

Referring to fig. 1, two ends of a body 1 are respectively connected with a first pipe ring 4 and a second pipe ring 5, so that the body 1 can be conveniently installed on a machine needing heat exchange through the first pipe ring 4 and the second pipe ring 5. First pipe ring 4 all adopts stainless steel material preparation to form with second pipe ring 5, avoids first pipe ring 4 and second pipe ring 5 to corrode because of rust in long-time use, increases first pipe ring 4 and second pipe ring 5's life.

Please refer to fig. 4, the filter screen 6 is detachably connected inside one end of the body 1, and the filter screen 6 is arranged to filter the dust impurities in the liquid, so as to prevent the dust impurities from entering the finned tubes along with the high-temperature liquid, and being adsorbed in the finned tubes to cause the blockage of the finned tubes and affect the heat dissipation efficiency.
