Embodiment Construction

[0050] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0051] like Figure 2a , 2b , shown in 2c, according to a kind of accumulator of the first embodiment of the present invention, comprises: air inlet and outlet pipe; Cylinder, it has welding hole 15 (as Figure 16a , 16b, 17a, 17b). The welding hole 15 is connected with the air inlet and outlet pipes by resistance welding, that is, the welding places A and B are connected by resistance welding. The cylinder body includes an upper cylinder body 2 and a lower cylinder body 4, and the upper cylinder body 2 and the lower cylinder body 4 are welded by carbon dioxide shielded welding or argon arc welding. The air inlet and outlet pipes can be steel pipes coated with copper on the inner and outer surfaces, so as to be connected with the air-conditioning pipelines. According to specific conditions, the air inlet and outlet pipes can be ...

Abstract

The invention provides a liquid reservoir comprising an air inlet tube, an air outlet tube, and a cylinder body, the cylinder body is provided with weld pores, and the weld pores are connected with the air inlet tube and the air outlet tube by electric resistance welding. The invention also provides an air-conditioner comprising the above liquid reservoir. In the embodiment of the invention, a manufacture method of the air-conditioning liquid reservoir is also provided, which is implemented by welding the air inlet tube and the upper cylinder body by electric resistance welding; welding the air outlet tube and the lower cylinder body by electric resistance welding; and welding the upper cylinder body and the lower cylinder body by carbon-dioxide shielded welding or argon-arc welding. The invention overcomes the problem that the copper plating layer of the air inlet tube and the air outlet tube of an existing liquid reservoir is easy to destroy by high temperature and to generate shedding and bubbling on the surface of the plating layer so as to affect the welding effect, thus the invention can achieve good welding effect and low cost.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a liquid accumulator, a manufacturing method thereof, and an air conditioner. Background technique [0002] The material used for the air inlet and outlet pipes of the liquid receiver is copper, and the welding process between the air inlet and outlet pipes and the cylinder is mostly flame welding, furnace brazing, and high-frequency welding. The welding materials are silver solder, brass solder, and phosphor bronze. Solder; products processed by the above process have high material cost and welding cost, and the working environment is poor. [0003] In order to reduce the cost of product materials, some manufacturers change the material of the air inlet and outlet pipes to steel. After the air inlet and outlet pipes are processed, the surface is simply degreased, and after pickling, they are assembled with the cylinder of the liquid reservoir and welded. The welding method is Integ...
