Detachable finned air-cooled heat exchanging pipe

Abstract

The invention discloses a detachable finned air-cooled heat exchanging pipe. The detachable finned air-cooled heat exchanging pipe comprises an air-cooled pipe, a finned pipe, a heat conductor and anannular plug. The air-cooled pipe is connected with a heat exchanging port of an air-cooled unit, and connection ports are formed in the two ends of the air-cooled pipe. A plurality of layers of finsare horizontally fixed to the outer side of the finned pipe along the axis, and the finned pipe is mounted on the outer side of the air-cooled pipe in a sleeving mode. The position between the air-cooled pipe and the finned pipe is filled with the heat conductor. An inner ring of the annular plug is mounted on the air-cooled pipe in a sleeving mode, and an outer ring of the annular plug is in sealing fit with the port of the finned pipe. The detachable finned air-cooled heat exchanging pipe is simple in structure, the finned pipe is convenient to dismount, the heat exchanging capability of anair-cooled heat exchanging pipe in the winter can be reduced, and thus a pipe bundle can be prevented from being frozen. The heat exchanging capability of the air-cooled heat exchanging pipe in the summer can be improved, the backpressure of the unit is lowered, and thus the requirements for heat exchanging effects of the air-cooled heat exchanging pipe of the three Norths in the winter and the summer can be met at the same time.

Description

Technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a detachable fin type air-cooled heat exchange tube. Background technique [0002] In recent years, in response to the national energy-saving and emission reduction policies, air-cooled units are mostly used in newly-built power plants in the Three Norths. However, the three-North regions have large annual temperature differences, low temperatures in winter and high temperatures in summer. In order to ensure efficient use of energy, air-cooled heat exchange needs to be enhanced in summer. The heat exchange effect of the air-cooled heat exchanger needs to be reduced in winter. However, the commonly used heat exchange tubes of air-cooled units cannot meet the heat transfer effect of the heat exchange tubes of air-cooled units in the Three Norths region in both winter and summer. In addition, the heat exchange tubes of air-cooled units are mostly in the form of fins, but the fin...

Problems solved by technology

However, the commonly used heat exchange tubes of air-cooled units cannot meet the needs of the heat exchange effect of the heat exchange tubes of air-cooled units in winter and summer in the Sanbei region at the same time

In addition, the heat exchange tubes of air-cooled units mostly use fins, but the fins of finned tubes are often thin, and are easily squeezed and deformed during transportation. The deformed fins may block the air flow, forming a flow dead zone, causing The heat transfer effect becomes worse
