AI Technical Summary

Technical Problem

Existing heat exchangers, particularly catalytic ones used for hydrogen liquefaction, face complexity in design and catalyst distribution, requiring numerous pipes and increased catalyst volume, with non-uniform distribution and complex filtration systems.

Method used

A heat exchanger with inlet and outlet filters made of sheet-like metallic materials, such as metal gauze or sintered metal fibers, integrated into the manifold to control catalyst distribution and simplify assembly, reducing catalyst volume and enhancing uniformity.

Benefits of technology

Simplifies manufacturing and assembly, ensures uniform catalyst distribution, and reduces catalyst usage while maintaining efficient filtration, thereby improving thermal and hydraulic performance.

Abstract

To provide a heat exchanger having a filtering device which can easily and further favorably control a hold of a catalyst in a passage, and a charge of the passage during the manufacturing of the heat exchanger.SOLUTION: A heat exchanger comprises: an exchanging body 1 having a plurality of first passages for a first fluid, and a plurality of second passages for a second fluid which exchanges heat with the first fluid; a first inlet manifold for introducing the first fluid into the first passages; and a first outlet manifold for discharging the first fluid. The heat exchanger also comprises an inlet face 11 at which the first passages are fluid-connected to the first inlet manifold, and an outlet face which is fluid-connected to the first outlet manifold. The heat exchanger further comprises an inlet filter 31 disposed while facing the inlet face of the exchanging body 1, and / or an outlet filter disposed while facing the outlet face of the exchanging body 1. The inlet filter 31 and / or the outlet filter includes a sheet-shaped metal material 30 which is selected from a metal gauze, a metal fiber non-woven cloth, sintered metal powder, and sintered metal fibers.SELECTED DRAWING: Figure 4
