Modularized concatenation heat exchanger and producing method thereof

Abstract

The invention discloses a modularized concatenation heat exchanger. The modularized concatenation heat exchanger comprises a plurality of heat exchanging modules, each heat exchanging module comprises a heat exchanging plate and a heat exchanging pipe, a convex pillar cone and a concave pillar groove are formed in the two sides of the plane where the heat exchanging plate is located correspondingly, and the convex pillar cone of each heat exchanging module is in concatenation with the concave pillar groove of the adjacent heat exchanging module. The invention relates to the field of heat exchangers, the heat exchanging pipes are installed on the heat exchanging plates, and thus the heat exchanging modules are formed; and the heat exchanging modules are connected in series to form main parts of the heat exchanger through cooperation of the convex pillar cones and the concave pillar grooves which are installed on the heat exchanging plates, concatenation among the heat exchanging modules does not need assistance of other external auxiliary measures, the installing technique is simple, and dismounting and cleaning are facilitated.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a modular serial heat exchanger and a manufacturing method thereof. Background technique [0002] A heat exchanger is an energy-saving device that realizes heat transfer between materials between two or more fluids at different temperatures, so that heat is transferred from a fluid with a higher temperature to a fluid with a lower temperature, so that the temperature of the fluid reaches the process specification indicators, to meet the needs of process conditions, while improving energy utilization. [0003] With the development of science and technology, the structure types of heat exchangers tend to be diversified to meet the actual production and application. Among them, the shell-and-tube heat exchanger, also known as the tube-and-tube heat The partition wall heat exchanger with the wall as the heat transfer surface has a relatively simple structure and reliable operation. It...

Problems solved by technology

At the same time, this structure realizes the functions of corrosion resistance, high temperature resistance, high pressure resistance and anti-fouling, but the cost is high

[0008] However, fixed tube-sheet heat exchangers, floating head heat exchangers, and U-tube heat exchangers have poorer heat transfer effects than finned heat exchangers. Fins are installed to achieve the purpose of enhancing heat transfer, but it is precisely because of the setting of fins that it is difficult to remove dirt, and the accumulation of dirt will reduce the heat transfer coefficient and affect the heat transfer effect

If fins are added to the heat exchange tubes of the shell-and-tube heat exchanger, the tube bundle cannot be drawn out, which is not conducive to shell-side cleaning
