Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problem of preventing the rotation of the connecting pipe when the main body of the heat exchanger is welded to the connecting pipe, the present invention provides a connecting pipe assembly structure of a plate heat exchanger. The connection hole is sealed and connected, and the positioning part is fastened in the positioning device, so that the connecting pipe can be reliably positioned on the heat exchanger body, and the staff does not need to fix the connecting pipe by hand for welding, which not only ensures that the eyes of the staff are not hurt , and greatly improved the success rate of welding

Abstract

The invention relates to the technical field of heat exchangers, in particular to a plate type heat exchanger connecting pipe assembly structure. The late type heat exchanger connecting pipe assemblystructure comprises a body and connecting pipes. A connecting hole is formed in the body. A positioning device is arranged at the bottom of the connecting hole. The connecting pipes comprise connecting ends matched with the connecting hole. The connecting ends comprise expansion areas and welding areas. Positioning parts are arranged at the end portions of the expansion areas. The expansion areasare connected with the connecting hole by the expanding pipe technology in a sealing mode, and the positioning parts are fastened in the positioning device. The welding areas are connected with an endopening of the connecting hole in a welding mode, the expansion areas are connected with the connecting hole by the expanding pipe technology in a sealing mode, and the positioning parts are fastenedin the positioning device, so that the connecting pipes are reliably positioned on the heat exchanger body, a worker does not need hands to fix the connecting pipes for welding, it is ensured that the eyes of the workers are not injured, and the success rate of welding is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a connecting pipe assembly structure of a plate heat exchanger. Background technique [0002] Heat exchangers are widely used in the process industry to transfer heat between process materials. During the manufacture and use of plate heat exchangers, the reliability of the body of the heat exchanger and the connecting pipe directly affects the quality of the heat exchanger. When the existing heat exchanger is connected to the connecting pipe, it is mainly welded, and then During the welding process, since the connecting pipe will rotate in the connecting hole in the heat exchanger body, it is necessary for the staff to fix the connecting pipe with one hand and weld with the other hand, which prevents the staff from using welding protection. The cover protects the eyes of the staff, thereby causing damage to the eyes of the staff, and the success rate of welding is low; i...
