Problems solved by technology

[0003] At present, the water trays used for the collection and discharge of condensed water in the air conditioning system are mostly made of metal materials, such as stainless steel or galvanized sheet materials; these metal products will have electric welding, butt welding, wind welding, general stamping Processes such as extension and electroplating lead to complex and cumbersome processing; in the process of processing and preparing water trays, defects such as desoldering, cracking, and welding holes are prone to occur, which makes the product safety and quality hidden dangers
The processing and forming performance of the water receiving tray in the prior art is not good, and a large amount of heat energy is required in the processing process, and the production cost is high
[0004] In addition, due to the large proportion of the metal material used in the prior art, it is laborious to transport and replace; and the heat insulation performance of the metal material is poor, and the condensed water is easy to freeze in winter and cannot be effectively discharged; the resistance of the metal material Good impact performance but poor deformation recovery performance after impact, coupled with the corrosive effect on acid-base salts in the air, poor weather resistance, which is not conducive to long-term and repeated use

Description

technical field [0001] The invention relates to a preparation method of a material, in particular to a production method of an air-conditioning fan coil water receiving pan. Background technique [0002] When the air-conditioning system is running, the air passes through an object whose surface temperature is lower than its dew point temperature, and a part of the water vapor in the air condenses into water droplets on the surface of the object, thus forming air-conditioning condensate; Proper collection and discharge is required both inside and outside the building. [0003] At present, the water trays used for the collection and discharge of condensed water in the air conditioning system are mostly made of metal materials, such as stainless steel or galvanized sheet materials; these metal products will have electric welding, butt welding, wind welding, general stamping Delamination, electroplating and other processes lead to complex and cumbersome processing; in the proce...
