Header body shell tube communication pressure-bearing heat exchanger

Abstract

The invention discloses a header body shell tube communication pressure-bearing heat exchanger. The header body shell tube communication pressure-bearing heat exchanger comprises two header bodies. Stiffening objects are arranged on the spacing board faces between header inner side pore plates and pipe holes of a plurality of shell circular pipes or / and circular ring stiffening plates are arranged in pipe openings of the multiple shell circular pipes. The stiffening objects are transversely welded to the header inner side pore plates to form T-shaped stiffening ribs. At least one pipe heat exchanging pipe or a combined heat exchanging pipe is arranged in each pipe cavity of the multiple shell circular pipes. The heat exchanging pipes or the combined heat exchanging pipes are held to bent pipes in inner cavities of headers to be communicated or be communicated by welding communication pipes. The inlet ends and the outlet ends of the heat exchanging pipes or the inlet ends and the outlet ends of the combined heat exchanging pipes are communicated by welding third pipe connectors and fourth pipe connectors to form pipe pass fluid circulation heat-transmission flowing channel. Two medium fluid in a heat exchanger passes through pipe passes of the heat exchanging pipes or the pipe passes of the combined heat exchanging pipes and / or the shell passes of the inner cavities of the headers and the shell passes of the multiple shell circular pipes to conduct heat exchanging. According to the header body shell tube communication pressure-bearing heat exchanger, the heat exchanging area is large, the header body shell tube communication pressure-bearing heat exchanger efficiency is high, and installation materials are saved.

Description

[0003] The above-mentioned three prior...

AI Technical Summary

Problems solved by technology

[0007] It can be seen from the above that the welded connection structure of the cold fluid header heat exchanger in the prior art is unstable or unreasonable or the cost is high

There are also defects that the four inlet and outlet pipe joints are installed on the header part at one end, and the shell and tube cannot be installed vertically, or the setting and manufacturing of the shell-side channel and the tube-side channel are not flexible enough, and the heat exchange area is small and the thermal efficiency is low.
