Abstract
The utility model relates to a finned evaporator including a first coil pipe and a second coil pipe. Fins are arranged on the first coil pipe and the second coil pipe in a expanded manner. The surfaces of the first coil pipe and the second coil pipe are both provided with acrylic paint protection layer. The finned evaporator provided by the utility model has an advantage of being good in weatherability.
Description
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.On the aluminum pipe of existing finned evaporator and fin, all do not carry out weatherability treatment, cause the weatherability of product poor.
In addition, 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 finned evaporator of the present utility model has advantages of good weatherability.
The technical scheme solving the problems of the technologies described above is as follows:
A finned evaporator, comprises the first coil pipe, the second coil pipe, and on the first coil pipe and the second coil pipe, all swelling has fin, and the surface of the first coil pipe, the second coil pipe and fin is equipped with acrylic paint protective layer.
Adopted such scheme; the utility model is equipped with after acrylic paint protective layer on the surface of the first coil pipe, the second coil pipe and fin; because acrylic paint protective layer has fast drying; adhesive force is good; heat resistance, weather resistance are good; therefore,, after acrylic paint protective layer is arranged on the first coil pipe, the second coil pipe and fin, make heat resistance, the weather resistance of finned evaporator integral body all there is significantly lifting.
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.
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 avoid completely producing electrochemical corrosion between coil pipe and copper connecting tube, extend the service life of finned evaporator.
