Description

Technical Field

[0001] This utility model relates to the field of heat recovery technology, and more specifically, to a spiral high-efficiency heat exchange tube. Background Technology

[0002] Heat exchange tubes are commonly found in shell-and-tube, tubular, and double-tube heat exchangers in petroleum, chemical, power, and refrigeration equipment, and their applications are widespread. Selecting good heat exchange tubes results in high heat transfer efficiency, inhibits fouling, and improves product reliability and economy. Publication number (CN206847454U) describes a spiral high-efficiency heat exchange tube, comprising lead tube sections at both ends and a heat exchange section located between the lead tube sections. The lead tube sections are smooth-walled circular tubes, and the heat exchange section is a hollow tube. The outer wall of the heat exchange section has a spiral portion that spirals and protrudes along the axis of the heat exchange section. Multiple spiral portions are arranged circumferentially along the heat exchange section, and these spiral portions are coiled together. The spiral portion and the heat exchange section share the same fluid chamber. The outer wall of the heat exchange section is a concave-convex wall surface. The outer wall includes outer wall protrusions arranged in a row and protruding from the outer wall, and an outer wall recess located between two outer wall protrusions. The inner wall of the heat exchange section is also a concave-convex wall surface. The inner wall includes elongated inner wall protrusions arranged in parallel and protruding from the inner wall, and an inner wall recess located between two inner wall protrusions.

[0003] When the above-mentioned device is in use, it is equipped with uneven walls to increase the heat transfer area and enhance the turbulence of the fluid medium. The spiral part enhances the turbulence of the internal fluid medium, increases the heat transfer coefficient and inhibits the deposition of fouling. However, the uneven walls of the spiral part will increase the rate of fouling accumulation. When there is a lot of fouling, it will seriously affect the heat exchange efficiency of the heat exchange tube. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spiral high-efficiency heat exchange tube. The technical problem to be solved by the present invention is: how to increase the heat exchange efficiency of the heat exchange tube.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a spiral high-efficiency heat exchange tube, comprising a heat exchange tube with heat exchange water guiding holes inside, and heat exchange fins provided on the outer end face of the middle part of the heat exchange tube, the heat exchange fins passing through the end face of the heat exchange tube and extending into the interior of the heat exchange tube.

[0006] The heat exchange fins have contact heat exchange plates inside the heat exchange tube. One end face of the contact heat exchange plate has a first inclined groove, and one end face of the heat exchange fins has a second inclined groove.

[0007] In a preferred embodiment, the heat exchange tube is a copper component, and the number of heat exchange fins is multiple, arranged in a ring array outside the center point of the heat exchange tube in the right-view direction.

[0008] In a preferred embodiment, the heat exchange fins are arranged in a spiral configuration on the outer end face of the heat exchange tube, and the heat exchange fins are made of copper.

[0009] In a preferred embodiment, the second inclined groove is provided in two quantities and is arranged in a mirror image on both sides of the vertical central axis in the main view direction of the heat exchange fin. The first inclined groove is provided in two quantities and is arranged in a mirror image on both sides of the vertical central axis in the main view direction of the contact heat exchange fin.

[0010] In a preferred embodiment, the number of contact heat exchange plates is multiple, and they are arranged in a ring array outside the center point of the heat exchange tube in the right-view direction. The contact heat exchange plates are arranged in a spiral state on the inner end face of the heat exchange tube.

[0011] In a preferred embodiment, the length of the contact heat exchanger in the main viewing direction is less than the length of the heat exchange fin in the main viewing direction, and the contact heat exchanger is arranged in a staggered state on the inner end faces of adjacent heat exchange fins.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In practical use, the corresponding arrangement of the heat exchange fins and contact heat exchange plates increases the contact area between the heat exchange tube and the external heat exchange medium, thereby increasing the heat exchange efficiency of the heat exchange tube. At the same time, the contact heat exchange plates come into contact with the heat-conducting medium inside the heat exchange tube, which effectively increases the heat conduction efficiency of the heat exchange tube, further increasing the heat exchange efficiency and effect of the heat exchange tube. In addition, the corresponding arrangement of the second inclined groove and the first inclined groove can guide impurities in the heat exchange medium on both sides of the heat exchange tube to the outside, thereby preventing excessive impurities from accumulating in the gaps inside the heat exchange fins and contact heat exchange plates.

One end face of the contact heat exchange plate 4 is provided with a first inclined groove 5. There are two first inclined grooves 5, which are arranged in a mirror state on both sides of the vertical central axis of the contact heat exchange plate 4 in the main view direction. There are multiple contact heat exchange plates 4, which are arranged in a ring array outside the center point of the heat exchange tube 1 in the right view direction.

[0022] Working principle of this utility model:

[0023] When using this utility model, after the operator has installed it, external hot water is introduced into the heat exchange water guide hole 6 of the heat exchange tube 1. Then, the operator can immerse the outside of the heat exchange tube 1 in cold water. The contact heat exchange plate 4 and the heat exchange tube 1 can effectively absorb the heat in the hot water inside the heat exchange water guide hole 6, thereby effectively transferring it to the outer end face of the heat exchange tube 1 and the heat exchange fin 2. When the cold water flows through two adjacent heat exchange fins 2, it can effectively increase the efficiency and effect of heat recovery and exchange inside the heat exchange tube 1.
