Parallel flow heat exchanger and fin band structure thereof

Abstract

The invention discloses a parallel flow heat exchanger and a fin band structure thereof, and relates to the technical field of parallel flow heat exchangers. According to the parallel flow heat exchanger and the fin band structure thereof, the lower surface of the upper side of a buffer block is connected with the inner wall of a flat pipe through an elastic piece, the left side of the buffer block is fixedly connected with the outer wall of an exhaust pipe, and the upper side of the exhaust pipe communicates with a cavity formed between the outer wall of the buffer block and the inner wall of the flat pipe; the lower end of the exhaust pipe communicates with the outer side of the flat pipe, and the outer wall of the buffer block and the outer wall of the exhaust pipe are both in sliding connection with the inner wall of the flat pipe. According to the parallel flow heat exchanger and the fin belt structure thereof, when a water hammer effect generated by sudden stopping and starting of water flow is generated, the impact of the water flow enables the pressure on the upper side of the buffer block to be increased suddenly, so that the buffer block shifts, the lower side of the buffer block extends out of the interior of the flat pipe, the elastic piece is bent, deformed and buffered, and the pressure of the water hammer effect is released; the impact on the joint is reduced, and the purpose of protecting the joint is achieved.

Description

technical field [0001] The invention relates to the technical field of parallel flow heat exchangers, in particular to a parallel flow heat exchanger and its fin strip structure. Background technique [0002] The connection between the water tube and the flat tube of the parallel flow heat exchanger is more fragile than the body structure, and it is easy to accumulate water at the connection under the temperature difference between the inside and outside. The sudden start and sudden stop of the internal water flow will produce a water hammer effect, and its relatively fragile joints are more likely to break after being corroded, so it will cause a safety hazard. It is very important to remove the moisture condensed on the outer wall during use. Therefore, a device is required. It can reduce moisture condensation at the connection between the water pipe and the flat pipe during use, and protect the connection between the water pipe and the flat pipe.

[0002] The connection between the water pipe and the flat pipe of the parallel flow heat exchanger is more fragile than the main body structure, and it is easier to accumulate moisture at the connection under the temperature difference between the inside and outside. The sudden start and stop of the internal water flow will produce a water hammer effect, and its relatively fragile joints will be more likely to break after being corroded, which will cause safety hazards. How to remove the condensed water on the outer wall during use is very important, so a device is needed It can reduce moisture condensation at the connection between the water pipe and the flat pipe during use, and protect the connection between the water pipe and the flat pipe
