Abstract

The invention discloses a plate-fin type heat exchanger baffle spray-head structure sealing head. The plate-fin type heat exchanger baffle spray-head structure sealing head comprises a sealing head main pipe, a shell disposed at the bottom of the sealing head main pipe and an outlet surface arranged at the bottom of the shell. A circular ring is welded to the bottom of the sealing head main pipe,a baffle spray-head structure is arranged on the circular ring, the baffle spray-head structure includes baffles I, baffles II and a baffle III, the baffles I are arranged on both sides of the baffleIII, and the baffles II are arranged at the positions between the baffles I and the baffle III. The plate-fin type heat exchanger baffle spray-head structure sealing head has the beneficial effects that inflowing high-pressure gas can be injected to corresponding outlet regions by additionally arranging the baffle spray-head structure at the tail end of the main pipe, and the uniformity of flow distribution at each outlet is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of multi-channel heat exchanger head structure, in particular to a head with a baffle nozzle structure for a plate-fin heat exchanger. Background technique

[0002] Due to its compact structure, light weight, high heat transfer efficiency, and strong adaptability, plate-fin heat exchangers are widely used in many fields such as air separation equipment, petrochemical, transportation equipment, and aerospace. Among them, in the air separation equipment, the plate-fin heat exchanger is the key equipment for heat exchange such as condensation, liquefaction, and evaporation. The heat exchange efficiency directly determines the energy consumption in the air separation process, which has an important impact on economic benefits. influences. Uneven inlet flow distribution is a common problem of low heat exchange efficiency of plate-fin heat exchangers. This problem can be greatly improved by innovating and improvi...
