Technical Field
The invention relates to the field of refrigeration equipment, in particular to a gas collector for internal and external flanging of a special air conditioner and a manufacturing method and application thereof.
Background
The conventional commercial air conditioner generally consists of an external unit and a host, works by switching on a power supply, has relatively simple requirements on the assembly size of the gas collector, and the flanging hole of the gas collector adopts an inward flanging or outward flanging mode. In reality, a special air conditioner used in a special environment is also provided, and the special air conditioner is an air conditioner product specially designed and manufactured for meeting air conditioning requirements of certain special environments and process places. The special air conditioner does not necessarily work by using electric energy, and can work by burning coal or even burning gas (namely methane), so the welding quality requirement of the gas collector of the air conditioner needs to reach 100 percent of qualified rate, and zero defect and zero error are required. For example, special air conditioners mainly applied to high-speed rails, subways and even military refrigeration systems adopt methane as power, the special air conditioners require zero leakage for welding parts of a gas collector, the melting depth of welding materials must meet the requirements by 100%, and higher requirements are provided for the noise and the welding quality of the air conditioners.
The flanging hole of the gas collector can ensure the consistency of the fluid flow by adopting a flanging mode, but the welding difficulty is high, and the quality and the leakage rate are difficult to ensure by manual welding at present. Based on this, many air conditioner accessory producers change the mode of inside flanging, and rethread polishing burring process improves welding quality, but even so, the leakage rate after the welding of gas collector can only be controlled to 50PPM at present, still can not accomplish zero defect. And some special air conditioners used in special environments, such as air conditioners used in underwater operation environments, also need to require the consistency of the flow inside the air conditioner after the air conditioner is started, ensure the consistency of noise after the refrigeration equipment is started, and have very high requirements on noise. However, the gas collector products on the market at present cannot simultaneously ensure the flow consistency and the zero leakage rate, and are difficult to meet the quality standard of special air conditioner accessories used in special environments.
