Aiming at the problem of high price of copper materials, manufacturers are researching and designing to replace the copper materials with cheap metal materials so as to increase the comprehensive competitiveness of enterprises by reducing the production cost. However, the replacement of the evaporator outlet tube assembly material requires overcoming two problems: the anti-rust and anti-corrosion problem of the replacement material is that the copper material has good anti-rust and anti-corrosion performance, and even if the connecting pipe section and the pipe joint of the outdoor compressor in the evaporator output pipe assembly are exposed to the outdoor environment by using the copper material, the requirement on the service life of the evaporator output pipe assembly can still be met, but the connecting pipe section and the pipe joint of the outdoor compressor are subjected to anti-rust and anti-corrosion treatment by using a stainless steel material with relatively low price or a carbon steel material with lower price, so that the bottleneck problem is faced; two, the replacement material is with the sealing weld problem of copper product junction, some manufacturing enterprises are in order to be at reduce cost, carry out the replacement of part coupling pipe section with the evaporimeter output tube subassembly of present copper product, easy rust corrosion coupling pipe section and coupling still use the copper product promptly, and other difficult rust corrosion coupling pipe sections use the stainless steel material of low price relatively or the carbon steel material replacement of lower price, however sealing weld between the different materials is the bottleneck problem that faces, if the welding effect is not good, the refrigerant leakage phenomenon takes place easily in the welding department of different materials, and then influence the life of whole evaporimeter output tube subassembly.

The technical scheme simple structure that this patent was disclosed, the leakproofness is good, simple to operate, and the evaporimeter delivery pipe subassembly that the stainless steel made has not only reduced manufacturing cost, has still increased life. However, the stainless steel material with relatively low price is selected in the technical scheme of the patent, so that the production cost of an enterprise can be reduced to a certain extent, but the stainless steel material with relatively low price still has no price advantage corresponding to the carbon steel material with relatively low price, so that the comprehensive competitiveness of the enterprise cannot be better increased, the technical scheme of the patent also does not specifically disclose the rust-resistant and corrosion-resistant treatment of the stainless steel material, only the theoretical analysis is carried out from the material replacement angle, and the service life of the stainless steel material cannot be longer than that of an output pipe assembly of a copper evaporator. Use carbon steel material replacement can maximum reduction material cost, but the single carbon steel material replacement that uses can't satisfy life's requirement again well, if whole connecting pipe section integrated into one piece and with the sealed welding of coupling after carry out rust-resistant anticorrosive treatment, undoubtedly the cost will increase again, play the effect of maximum reduce cost.
