PIPELINE CONNECTING STRUCTURE FOR HEAT EXCHANGER

WIPO Patent Application WO/2011/143952

A1

A pipeline connecting structure for heat exchanger comprises a connecting pipe (1), a heat-radiation straight pipe (2), a first positioning block (3), a second positioning block (4) and an elastic component (5). The connecting pipe (1) and the heat-radiation straight pipe (2) are connected with each other by plugging end portions, and a seal ring (6) is provided between the pipe walls of the heat-radiation straight pipe (2) and the connecting pipe (1) at the splicing place. The first positioning block (3) is fixed on an outer wall of the connecting pipe (1), and the second positioning block (4) is fixed on an outer wall of the heat-radiation straight pipe (2). Two ends of the elastic component (5) are respectively connected with the first positioning block (3) and the second positioning block (4). The pipeline connecting structure is convenient to install and welding process is omitted, thereby the phenomenon of breaking a welded junction easily during transportation is completely avoids. A sealing calandria structure can be changed along with the change in the volume of the medium in the pipe at a sealing state without breaking, so as to reduce the managing cost of the heat exchanger during the running process.
