Plate-shell heat exchanger

Abstract

This invention discloses a board shell type heat interchanger, its main package loam board tube control, shell, tube Cheng Yuke regulation import and export; States the board tube control by the stack-up to combine in the together compound flow channel ripple slab composes, in each piece of slab plane arranges in turn has V shape concavity ripple trough, states the ripple trough according to assume the mutually perpendicular neighboring, and two kind of different orientation's ripple trough vertical side becomes an acute angle separately with slab two orientation, states slab, reverse side relative combination, forms the mutually perpendicular in its neighboring two interior, and gap heat transfer tube Cheng Heke regulation two kind of compound flow channels; States the tube regulation flow channel both sides through to pass in and out the oral siphon box and the belt separately inflates the festival the export to connect; States the shell regulation both sides to connect separately with the shell regulation import and export. This invention has at the same time the disc heat interchanger heat transfer efficiency to be high, compact is good and the shell type heat interchanger sturdy construction the merit, simultaneously it has overcome former disc heat interchanger bearing pressure ability difference and the shell type heat interchanger heat transfer efficiency is low and structure huge shortcoming.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a device used for heat exchange between two fluid media in the fields of petroleum refining, chemical industry, electric power, metallurgy and the like. Background technique [0002] The heat transfer tubes used in the current shell and tube heat exchangers are circular tubes. According to national standards, the most commonly used tube diameters for shell and tube heat exchangers are 25mm and 19mm. The advantages of this kind of heat exchanger are firm structure and high elasticity, but the disadvantages are low heat transfer efficiency, poor compactness, and takes up a large space. In addition, a plate and shell heat exchanger has appeared in recent years, which is characterized by high compactness and heat transfer efficiency, but its disadvantage is that the corrugated shape of the plate is single and the heat transfer coefficient is not high. At the same time, its pressure bearing...
