Problems solved by technology

However, the effects of these three types of heat exchangers are not good for medium and low temperature gas-liquid heat exchange. The existing technology is a blind spot for medium and low temperature gas heat exchange, which affects the further improvement of the energy efficiency of the system.

Abstract

The invention discloses a shell-and-plate heat exchanger with an asymmetric structure and a manufacturing method thereof. The heat exchanger comprises a shell pass shell, a plate pipe bundle which is arranged in the shell pass shell, and a pipe pass box body, wherein the plate pipe bundle comprises a plurality of plate pipes; the end part of each plate pipe is provided with a liquid inlet pipe joint and a liquid outlet pipe joint; the liquid inlet pipe joint and liquid outlet pipe joint of each plate pipe are respectively fixed at a liquid inlet pipe plate part and a liquid outlet pipe plate part; the pipe pass box body is divided into a liquid inlet pipe pass box body provided with a liquid inlet and a liquid outlet pipe pass box body provided with a liquid outlet; and the liquid inlet pipe pass box body and the liquid outlet pipe pass box body are respectively and correspondingly arranged on the liquid inlet pipe plate part and the liquid outlet pipe plate part. The shell-and-plate heat exchanger with the asymmetric structure has the advantages of compact and simple structure, small overall size, low cost, convenience for installation, small gas side resistance, flexible heat exchange combination, wide application fields and media, and capability of solving the problems, such as application fields, temperature ranges, mediums, costs, mediums, costs, gas side resistances, installation site and the like of gas-liquid heat exchangers.

Description

technical field [0001] The invention belongs to heat exchange equipment, in particular to a plate-shell heat exchanger with an asymmetric structure and a manufacturing method thereof. Background technique [0002] Existing gas-liquid heat exchangers mainly include plate-shell heat exchangers, finned-tube heat exchangers and shell-and-tube heat exchangers. Among them, the design and manufacture of plate-shell heat exchangers are complex, costly, and heavy. , the installation is inconvenient, the manufacturing process is more complicated than the shell-and-tube heat exchanger, the welding volume is large and the requirements are high, so its promotion and application are limited. The heat transfer area and heat transfer coefficient of the finned tube heat exchanger are limited, and at the same time, the cleaning is limited, the volume is large, the cost is high, and the gas side resistance loss is large. The shell-and-tube heat exchanger has a larger volume, the heat transfer...
