Refrigerated container loopback laminated integral connecting pipe assembly

Abstract

The invention discloses a refrigerated container loopback laminated integral connecting pipe assembly. The assembly comprises a loopback laminated integral pipeline, heat-shrinkable pipe sleeves and positioning buckles. The loopback laminated integral pipeline is provided with a loopback laminated portion, a longitudinal vertical bend portion and a same-plane return bend portion. The longitudinalvertical bend portion is located on the upper right portion of the loopback laminated portion, the same-plane return bend portion is located on the upper left portion of the loopback laminated portion, the heat-shrinkable pipe sleeves are mounted on the outer surface of part of the loopback laminated integral pipeline in a sleeving mode, and the positioning buckles are fixedly mounted on the outerside of the loopback laminated portion, so that the loopback laminated portion can be in tight contact and attached into a whole. According to the refrigerated container loopback laminated integral connecting pipe assembly, the effective reflux pipeline length of a refrigerant in a refrigerated container can be increased in a limited space, the energy-saving effect is good, the performance of thepositions where pipe ends of a reflux connecting pipeline assembly are welded to a compressor interface end and a refrigerated evaporator pipe end is good, the amount of residue and overlaps is small, the problems of damping and noise reduction of a multi-layer laminated reflux connecting pipeline are solved, and the noise reduction performance is good.

Description

technical field [0001] The invention relates to the field of a loop-back laminated integrated connection pipe assembly for a refrigerator, in particular to a loop-back laminated integrated connection pipe assembly for a refrigerator. Background technique [0002] The people use refrigerators and freezers to store and store food. At the same time, in order to meet the transportation, storage and preservation of food, medicine or reagents and other items over a long distance and for a long time, the people have developed different types of refrigerators that can meet the actual use requirements. The refrigerator mainly uses the compressor to drive the refrigerant refrigerant, which runs in the evaporator and connecting pipeline components, and then realizes the function of cold storage of food, medicine or reagents and other items. The pipeline assembly connected to the refrigerator can make the refrigerant running in the evaporator flow back, and then provide power through th...

Problems solved by technology

However, the connecting pipe assemblies of common refrigerators have the following problems in actual use: 1. Because the assembly space of the connecting pipe assemblies of refrigerators is limited, people usually use single-layer connecting pipe assemblies to connect with evaporators and compressors. The design makes the length of the effective return pipe connecting the pipe components short, and the overall heat absorption and temperature rise of the refrigerant is not sufficient, so the subsequent compression cycle is directly carried out, which consumes some unnecessary energy and does not save energy; 2. The compressor will vibrate during operation, Sometimes it will cause the overall vibration of the connecting pipe assembly. There is no buffer and shock absorbing layer on the outer surface of the ordinary connecting pipe assembly, which makes the overall vibration and noise of the connecting pipe assembly relatively large. Sometimes, although some ordinary connecting pipe Buffer shock absorption and fixed connectors, the shock and noise reduction effect of ordinary multi-layer connecting pipe components is worse, and the vibration noise is greater; 3. The pipe end design or treatment of ordinary refrigerator connecting pipe components is unreasonable, making the connecting pipe components The welding performance between the pipe end of the pipe end and the compressor interface end and the refrigerating evaporator pipe end is poor, and the welding residue is large, which leads to the welding of the pipe end connecting the pipe assembly and the compressor interface end and the refrigerating evaporator pipe end. Low strength and short service life
