Works outlet swirl diffusers workflow utilizing a rotating aluminum outlet when the wind, the air sent to the spiral, resulting in very high induction ratio, so that air from the surrounding room air rapidly mixing. With conventional diffuser different swirl diffusers of the duct radially arranged air duct in the guide by the cyclone outlet duct, forming a jet tangential direction (see Figure 1), the entire outlet air in a multi-role jets, resulting in a group, such as a typhoon-like vortex. The central region of the vortex forming a negative pressure zone, induced by rapid mixing of indoor air surrounding single aluminum vent and air, the entire air flow is steady-state level of diffusion flow. Its induction ratio is 10-20 times that of conventional diffusers. Aluminum outlet welded joints and other strong aging strengthening of all aluminum, after welding, whether through aging treatment, which failed to reach the level of the joint plastic base material. To weld, since the cast structure, even in the annealed condition and weld composition with essentially the same conditions as the base material, the strength may be very different aluminum outlet, but is generally not as good as the plastic weld base metal. If the weld composition different from the base metal, the weld will be mainly determined by the performance of the welding material to be used. To ensure the weld strength and ductility, solid solution strengthening type alloy system is superior to the eutectic alloy systems. Generally square aluminum outlet, the greater the energy of welding wire, welding performance decline is greater. For the fusion zone, in the aging strengthening aluminum welding, in addition to grain coarsening, but also may be due to the grain boundary microcracks generated liquefaction. Therefore, changes in the fusion zone is mainly plastic deterioration. In short, aluminum should be light weight, corrosion-resistant, easy to shape, etc; with the emergence of a new type of hard aluminum, aluminum and other superhard materials makes such materials performance continues to improve, which in aviation, aerospace, high-speed trains, high-speed industrial manufacturing ships, automobiles, has been more widely used. At the same time due to the large deformation of aluminum and its alloys due to the thermal expansion coefficient caused; easily oxidized when welding with inert gas protection needs; easy to produce pores, soften hot cracking and heat-affected zone, the intensity decreases problems. To solve this problem FSW as a new welding gradually welding aluminum and its alloys in a wide range of purposes. In-depth study of welding aluminum and its alloys is the development of a new aluminum alloy and solve their problems premise double welded aluminum outlet aluminum outlet _ _ Yi Tong Tong Yi air conditioning provided by the Texas Air Conditioning Equipment Co., Ltd ..
