Pipe communication splice welding pressure-bearing type heat exchanger

Abstract

The invention relates to a pipe communication splice welding pressure-bearing type heat exchanger, which comprises tap water heat absorption pipes. Heat supply pipes are arranged in the tap water heat absorption pipes. The tap water heat absorption pipes are communicated through tap water communication pipes. The heat supply pipes are communicated through heat supply pipe communication pipes. The seal heads of the tap water heat absorption pipes are outwardly flanged and embedded in the ports of the tap water heat absorption pipes. The flanges of the seal heads of the tap water heat absorption pipes and the port edges of the tap water heat absorption pipes are in splice bilateral alignment edge-kneading welding connection. The walls of the tap water heat absorption pipes are punched and inwardly flanged. The tap water communication pipes are inserted in the punches of the tap water heat absorption pipes. The port edges of the tap water communication pipes and the punched inward flanges of the tap water heat absorption pipes are in splice bilateral alignment edge-kneading welding connection. Heat supply pipe blocking plates are embedded in the ports of the heat supply pipes. The heat supply pipe blocking plates are outwardly flanged. The outward flanges of the heat supply pipe blocking plates and the port edges of the tap water heat absorption pipes are in splice alignment edge-kneading welding connection. According to the pipe communication splice welding pressure-bearing type heat exchanger disclosed by the invention, two technical defects of higher water leakage ratio of the welding line and incapability of continuously producing hot water of the original patent product can be solved; and the heat exchanger has the advantages of no leakage and continuous hot water production.

Description

technical field [0001] The invention relates to a heating heat exchanger which can be installed and used on a heating pipe network for heating and exchanging hot water for bathing, in particular to a pipe-connected and welded pressure-bearing heat exchanger. Background technique [0002] The patent No. 200720019175.2 applied by the applicant on March 10, 2007, the authorized announcement No. CN201021875Y, and the patented product named "Anti-scaling Counterflow Heat Exchanger" for the utility model have been applied for 3 heating periods after listing. There are two technical defects in the original patent: firstly, it is found that there are obvious deficiencies and defects in the welded joint structure and weld form of the shell pipe, end head, and connecting pipe; the heat transfer cannot meet the needs of users. At the beginning of use, the heat exchanger needs to be mixed with cold water for use, but the stored hot water is cooled instantly after being blended, and it t...
