Problems solved by technology

In actual production, because the relative position between the compressor connecting pipe 3 and the liquid receiver B pipe 4 is not fixed, it is easy to have bad brazing phenomena such as brazing skew, brazing broken welding, and weld lack of material, which makes the pipeline After the connection, the pipe joints cannot be completely sealed; there may also be defects such as insufficient solder penetration and brazing defects that are not easy to be found from the appearance inspection, which makes the working life of the refrigeration system shorter, and it is easy to cause accidents due to failure to detect defects in time occur

Embodiment 1

[0062] Figure 11A schematic structural diagram of a high-reliability compressor brazed pipe according to Embodiment 1 of the present invention is shown. In the first embodiment, the matching mode of the limiting section is selected as cylinder fitting. The structure of the accumulator B pipe 3 is a B structure, and the structure of the compressor connecting pipe 4 is a b structure. In the brazing section, a brazing seam is formed between the outer circumference of the accumulator B pipe 3 and the inner wall of the compressor connecting pipe 4; The inner wall of the compressor connecting pipe 4 is in close contact, so that the liquid accumulator B pipe 3 and the compressor connecting pipe 4 are relatively fixed in the radial direction. During the brazing operation, the brazing material 6 melts into the brazing seam and overflows into the reinforced brazing seam; after the brazing material 6 cools down, a sealing ring is formed to seal the compressor connecting pipe 4 and the...

Embodiment 2

[0064] Figure 12 A schematic structural diagram of a high-reliability compressor brazed pipe according to Embodiment 2 of the present invention is shown. In the second embodiment, the matching method of the limiting section is selected as cylinder fitting. The structure of the accumulator B pipe 3 is a B structure, and the structure of the compressor connecting pipe 4 is a g structure. In the brazing section, a brazing seam is formed between the outer periphery of the accumulator B pipe 3 and the inner wall of the compressor connecting pipe 4; in the limiting section, the outer periphery of the accumulator B pipe 3 and the compression The inner wall of the machine connecting pipe 5 is in close contact, so that the liquid receiver B pipe 3 and the compressor connecting pipe 4 are relatively fixed in the radial direction. During the brazing operation, the brazing material 6 melts into the brazing seam and overflows into the reinforced brazing seam; after the brazing material ...

Embodiment 3

[0066] Figure 13 A schematic structural diagram of a high-reliability compressor brazed pipe according to Embodiment 3 of the present invention is shown. In the third embodiment, the fitting mode of the limiting section is selected as taper fitting. The structure of the accumulator B pipe 3 is A structure, and the structure of the compressor connecting pipe 4 is D structure. In the brazing section, a brazing seam is formed between the outer circumference of the accumulator B pipe 3 and the inner wall of the compressor connecting pipe 4; in the limiting section, the end of the accumulator B pipe 3 is provided with a taper 11. The compressor connecting pipe 4 is provided with a corresponding taper 11, and the taper fits during assembly so that the position of the accumulator B pipe 3 and the compressor connecting pipe 4 are relatively fixed. During the brazing operation, the brazing material 6 melts into the brazing seam and overflows into the reinforced brazing seam; after t...

Abstract

The invention discloses a high-reliability compressor brazed pipe structure and a refrigeration system. The compressor brazed pipe structure includes a liquid accumulator B pipe and a compressor connecting pipe, and the liquid accumulator B pipe is connected to the compressor. At the connecting section of the pipe, a limiting section and a brazing section are arranged. Through the positioning of the limiting section, the relative position between the liquid receiver B pipe and the compressor connecting pipe is fixed; through the width design of the brazing seam of the brazing section, the penetration depth and welding range of the brazing material are guaranteed, thus having Reliable sealing performance.

Description

technical field [0001] The invention relates to the technical field of compressors, and mainly relates to a high-reliability compressor brazed pipe structure and a refrigeration system. Background technique [0002] The liquid receiver is installed between the discharge pipe of the evaporator and the suction pipe of the compressor to prevent liquid refrigerant from flowing into the compressor and causing liquid shock. The liquid receiver is mainly composed of an inlet pipe, a filter screen, an upper cylinder, a lower cylinder, a fixed plate, and an exhaust pipe. The inlet pipe is connected to the evaporator, and the outlet pipe is connected to the compressor suction pipe. In the industry, the The gas pipe is also called the reservoir A pipe, and the exhaust pipe is also called the liquid reservoir B pipe. During the operation of the system, the evaporator cannot guarantee that the refrigerant can be completely vaporized, and part of the refrigerant coming out of the evapora...
