Description

Technical Field

[0001] This utility model belongs to the technical field of air separation fins, specifically relating to an air separation fin with enhanced heat exchange area. Background Technology

[0002] "Air separation" is short for "air separation," which refers to the industrial process of separating different gaseous components (such as oxygen, nitrogen, argon, etc.) from the air using physical methods.

[0003] Air separation requires the use of air separation and utilization equipment. Fins need to be installed inside the air separation equipment. Fins are usually key components in finned heat exchangers. Their function is to improve heat exchange efficiency by increasing the heat exchange area and optimizing fluid flow.

[0004] However, since the fins need to be connected to the pipes, when heat is conducted directly through the fins, the air will be blocked by the pipes, preventing the air from flowing back over the surface of the fins and carrying away the heat inside the fins, thus making it impossible to quickly cool the gas inside the pipes.

[0014] Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the prior art:

The exhaust port is tilted backward to avoid generating significant turbulence on the gas, thereby increasing its heat exchange area. Attached Figure Description
