Description

Technical Field

[0001] This utility model relates to the field of heat exchange tube technology, and in particular to detachable heat exchange tubes. Background Technology

[0002] The wall surface of the heat exchange tubes in a tubular heat exchanger is the heat transfer surface used for heat exchange. During heat exchange, the heat exchange tubes do not easily accumulate condensate. The inconvenience of condensate drainage will affect the efficiency of normal heat exchange. In addition, the current heat exchange tubes are welded to the heat exchanger as a whole, which is inconvenient for cleaning and replacement, and will also affect the normal working efficiency.

[0003] For example, the utility model patent with authorization announcement number CN 221840243 U discloses a heat exchange tube, whose heat exchange section, when placed horizontally, is divided into a side prone to water accumulation and a side not prone to water accumulation; the concave portion of the side prone to water accumulation extends with both ends lower and the middle higher. This utility model, based on the need for improvements to liquid gas storage tanks, improves upon conventional heat exchange tubes. The concave polygonal cross-section of the heat exchange tube increases the heat exchange area and improves heat exchange efficiency; however, the heat exchange within this tube is inconvenient to install and disassemble, thus affecting subsequent maintenance and service life. Therefore, a detachable heat exchange tube is proposed. Utility Model Content
