Abstract

The utility model relates to a finned evaporator. The finned evaporator comprises a first coiled pipe and a second coiled pipe, and fins are expanded on both the first coiled pipe and the second coiled pipe. The finned evaporator is characterized in that an expanding copper connection pipe is welded on the end part of the first coiled pipe, the end part of the first coiled pipe and the welding part of the expanding copper connection pipe are coated with a first erosion resistant coating, a first shrinkable tube wraps the end part of the first coiled pipe and the welding part of the expanding copper connection pipe and comprehensively wraps the first erosion resistant coating, a shrinking copper connection pipe is welded on the end part of the second coiled pipe, the end part of the second coiled pipe and the welding part of the shrinking copper connection pipe are coated with a second erosion resistant coating, and a second shrinkable tube wraps the end part of the second coiled pipe and the welding part of the shrinking copper connection pipe and comprehensively wraps the second erosion resistant coating. The finned evaporator is effectively protected, and the service life of the finned evaporator is prolonged.

Description

Finned evaporator
Technical field
The utility model relates to a kind of finned evaporator.
Background technology
Finned evaporator is the most widely used a kind of heat transmission equipment in gas and liquid heat exchanger.Existing aluminum tube fin plate heat interchanger is general to be all welded direct to copper pipeline fitting in the input, delivery outlet of aluminium heat-exchange device, or from the input of aluminium heat-exchange device, one section of aluminum pipe of delivery outlet welding, then by copper pipeline fitting, be connected to the parts such as compressor, high pressure valve assembly.Between copper-aluminium joint or do not take any safeguard measure; only take simply the protection of spraying paint, practice shows, this class connected mode can not effectively be avoided the corrosion between copper-aluminium joint; along with go over service time, copper-aluminium joint often causes the leakage of cold-producing medium because of corrosion failure.Between copper and aluminium, have potential difference, once contact with water, copper-aluminium joint exists because potential difference causes producing electrochemical corrosion.Therefore, must adopt strong safeguard measure to copper-aluminium joint.
Summary of the invention
The purpose of this utility model is to provide a kind of finned evaporator, and the utility model has formed effectively protection to finned evaporator, makes to have obtained in service life of finned evaporator prolongation.
The technical scheme that realizes the utility model object is as follows:
A kind of finned evaporator, comprise the first coil pipe, the second coil pipe, equal swelling fin on the first coil pipe and the second coil pipe, the end of the first coil pipe is welded with an enlarging copper connecting tube, in the end of the first coil pipe and the weld of enlarging copper connecting tube, be coated with the first anticorrosive coat, first heat-shrink tube is coated on the end of the first coil pipe and the weld of enlarging copper connecting tube the first anticorrosive coat is comprehensively coated; The end of the second coil pipe is welded with a reducing copper connecting tube, in the end of the second coil pipe and the weld of reducing copper connecting tube, be coated with the second anticorrosive coat, second heat-shrink tube is coated on the end of the second coil pipe and the weld of reducing copper connecting tube the second anticorrosive coat is comprehensively coated.
Further, the length of described the first anticorrosive coat and the second anticorrosive coat is 30-50mm, and the length of the first heat-shrink tube and the second heat-shrink tube is 50-70mm.
Further, on the first coil pipe and the second coil pipe, be equipped with side plate, side plate is positioned near the curved bend pars convoluta of each dish, and side plate is provided with hole, passes accordingly the hole on side plate on the first coil pipe and the second coil pipe.
Adopted such scheme; weld by the end at the first coil pipe and enlarging copper connecting tube is coated with the first anticorrosive coat; and the weld of the end of the second coil pipe and reducing copper connecting tube is coated with the second anticorrosive coat; after weld having been formed to protection by the first anticorrosive coat and the second anticorrosive coat, can prevent from being welded on being corroded.By the first heat-shrink tube, be coated on the end of the first coil pipe and the weld of enlarging copper connecting tube the first anticorrosive coat is comprehensively coated; and second heat-shrink tube be coated on the end of the second coil pipe and the weld of reducing copper connecting tube the second anticorrosive coat is comprehensively coated; by the first heat-shrink tube, the first anticorrosive coat has been formed to protection; and second heat-shrink tube the second anticorrosive coat has been formed to protection; like this; can complete and avoid producing electrochemical corrosion between coil pipe and copper connecting tube, extend the service life of finned evaporator.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model finned evaporator;
Fig. 2 is the left view of Fig. 1;
In figure, 1 is the first coil pipe, and 2 is the second coil pipe, and 3 is fin, and 4 is enlarging copper connecting tube, and 5 is the first heat-shrink tube, and 6 is reducing copper connecting tube, and 7 is side plate.
