Abstract

Disclosed is a spiral modular type combined casing heat exchanger comprising heat exchanger tube bundle, spiral modular arranged in the heat exchanger tube bundle to spiral and wind with each other, and casing arranged in the spiral modular to spiral and wind with each other. The invention has the advantages of greatly reduced contact lines on the whole casing, more single points contacted, increasing the heat exchange area, decreasing the stagnating flow area and welt, and reducing the friction between dielectric fluid and the casing surface in the crack, so as to improve flow speed and enhance heat exchange.

Description

technical field

[0001] The invention relates to the structural composition of a casing heat exchanger, in particular to a spiral modular combined casing heat exchanger. Background technique

[0002] Fig. 1 is a cross-sectional structural schematic diagram of a single-row heat exchange tube casing heat exchanger in the prior art. As shown in the figure, two places on the circumference of each heat exchange tube 1 are in contact with the entire length of adjacent heat exchange tubes 1 , and the outer part of the tube bundle is in contact with the entire length of the casing 2 . Fig. 2 is a cross-sectional schematic diagram of a casing heat exchanger with double rows of heat exchange tubes in the prior art. As shown in the figure, there are 3 or 5 places on the circumference of each heat exchange tube 1 in contact with the entire length of the adjacent heat exchange tube 1 , and an average of 3.857 places in each tube are in contact with the entire length of the adjacent heat ...
