Problems solved by technology

However, welding is carried out at high temperature, and irritating gas is generated at the same time, which affects the environment, and the work intensity is high. The pipes are fixedly connected. The finished product is large in size and inconvenient to transport. In addition, it is easy to deform due to vibration or cold and heat. , resulting in leakage at the weld, making on-site maintenance difficult

Abstract

The invention discloses a pipeline connection structure of a heat exchanger, comprising a connecting tube, a heat-radiating straight tube, a first locating block, a second locating block and an elastic piece, wherein the connecting tube and the heat-radiating straight tube are sheathed, spliced and connected by an end part; a seal ring is arranged between the walls of the heat-radiating straight tube and the connecting tube at the splicing position; the first locating block is fixed on the outer wall of the connecting tube, the second locating block is fixed on the outer wall of the heat-radiating straight tube, and two ends of the elastic piece are respectively connected with the first locating block and the second locating block. The invention has the advantage that installation and arrangement are convenient, the working procedure of welding omitted, parts and components transportation of large rack tubes can be realized and installation on the spot is simple so that the phenomenon that welded junctions are easy to be damaged due to the transportation, and at the same time, the structure of the sealed rack tube is changed along with the variation of the volume of medium in the tube under the sealing without breaking and the management cost of the heat exchanger in the operation is lowered.

Description

technical field [0001] The invention relates to a pipeline connection structure, in particular to a pipeline connection structure for liquid transmission. Background technique [0002] In the existing tube heat exchanger, the heat exchange medium flows in the tube and exchanges heat with the air or liquid outside the tube through the tube wall. In order to increase the heat exchange area per unit volume of the heat exchanger, the heat exchange tubes are usually arranged in a manner of distributing a plurality of straight tubes on several planes. This produces the problem of connecting between straight pipes and straight pipes and between straight pipes and curved pipes. The usual way is to use welding to connect. However, welding is carried out at high temperature, and irritating gas is generated at the same time, which affects the environment, and the work intensity is high. The pipes are fixedly connected. The finished product is large in size and inconvenient to transpor...
