a heat exchanger

Abstract

The invention relates to a heat exchanger which comprises a heat exchange tube, a heat exchange device and a connecting device, the heat exchange tube is Z-shaped, the heat exchange device is installed in the heat exchange tube, and the end of the heat exchange tube is connected with the connecting device through threads. The problems that in the heat exchange process of an existing heat exchanger, an adopted connecting device is complex in mounting and dismounting process and multiple in operation step, and when a plurality of heat exchange pipes are connected, consumed time is too long, andmounting efficiency is low can be solved; meanwhile, the problems that in the heat exchange process of existing equipment, a heat exchanger matched with the existing equipment is needed to achieve different heat exchange temperatures, temperature adjustment cannot be achieved on the same heat exchanger, and therefore the production cost is increased, and the working efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchanger. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified indicators meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. Heat exchangers are mainly used in petroleum, chemical, metallurgy, electric power, ships, central heating, refrigeration and air conditioning, machinery, food, pharmaceuticals and other fields. [0003] At present, in the process of exchanging heat for heat exchangers, there are usually the following deficiencies: 1. When connecting existing equipment, the installation and disassembly process of the connecting devic...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem of the cumbersome installation and disassembly process of the connecting device used in the existing heat exchanger in the heat exchange process, and many operation steps. When connecting multiple heat exchange tubes, it takes too long and the installation Low efficiency; at the same time, in the heat exchange process of existing equipment, if you want to achieve different heat exchange temperatures, you need a matching heat exchanger, and you cannot adjust the temperature on the same heat exchanger, resulting in an increase in production costs. High, low work efficiency and other problems
