Description

A sealed subcooling box that can filter impurities

[0001] This application claims priority to the following Chinese patent application: Chinese Patent Application No. 202410835864.9, filed on June 26, 2024, entitled "A Sealed Subcooling Box for Filtering Impurities". The entire contents of the aforementioned patent application are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of heat exchangers, and more particularly to a sealed subcooling box capable of filtering impurities. Background Technology

[0003] The internal structure of a shell-and-tube heat exchanger generally consists of multiple components. Among them, the subcooling box, as an important part of the internal structure, extends the length of the shell-side medium flow path and increases the flow velocity between the tubes, thereby improving the heat transfer efficiency. Within the subcooling box, baffles installed between the baffles and the shell effectively block the medium undergoing flow, allowing the medium to pass through the baffles as much as possible, thus achieving a better heat transfer effect.

[0004] In typical baffle assemblies, the baffles and the shell are connected by intermittent welding or welding on both sides without welding in the middle. This connection method will result in a large assembly gap between the baffles and the shell, causing some media to leak out through the assembly gap instead of passing through the baffles, thus losing heat exchange efficiency.

[0005] In addition, some existing shell and tube heat exchangers lack internal filtration functions, and impurities in the fluid are prone to clogging the heat exchange tubes. With prolonged use, the filter components need to be disassembled and cleaned frequently. The disassembly and assembly process is cumbersome, time-consuming, and inconvenient for cleaning. Summary of the Invention

[0006] To address the aforementioned issues, this disclosure provides a sealed subcooling box capable of filtering impurities. Through sealing welding between the top plate, end plate, baffle plate, and bottom plate, the medium can pass through the baffle plate as much as possible, thereby achieving a better heat exchange effect. Simultaneously, impurities in the medium will be deposited outside the subcooling box inlet under the influence of gravity, thus enabling the subcooling box to filter impurities.

[0007] According to one aspect of the present disclosure, a sealed subcooled box capable of filtering impurities is provided, comprising a top plate, a bottom plate, two vertical end plates and a plurality of vertical baffle plates, the top plate is welded and installed above the bottom plate, the two end plates are respectively welded and installed at the left and right ends of the top plate and the bottom plate, and the plurality of baffle plates are welded and installed side by side between the top plate and the bottom plate; wherein one end of the bottom plate has an inlet hole, the other end has an outlet hole, a plurality of subcooled tube perforations are distributed on each of the end plates and the baffle plates, and a flow-through hole is provided on one side of each of the baffle plates, and the two flow-through holes on each adjacent two baffle plates are located on the left side and the right side.
