Description

Technical Field

[0001] This utility model relates to the field of heat exchange tube technology, and in particular to a high-efficiency condenser tube with a guide groove. Background Technology

[0002] Condenser tubes, as components of a heat exchanger, are placed inside the heat exchanger's shell to exchange heat between two media, and are widely used in air conditioning and other equipment. Typically, to improve heat exchange efficiency, fins are added to the surface of the heat exchange tubes to increase their outer surface area, thereby improving efficiency. However, the industry's requirements for the heat exchange efficiency of finned tubes are constantly increasing, and simple finned heat exchange tubes can no longer meet these demands. Utility Model Content

[0003] This utility model discloses a high-efficiency condenser tube with a guide groove, which mainly solves the problem that the heat exchange efficiency of traditional finned tubes cannot meet the requirements.

[0004] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0005] This utility model provides a high-efficiency condenser tube with a guide groove, including a tube body, a continuous spiral structure or multiple axially parallel fins distributed circumferentially along the outer surface of the tube body, and multiple concave guide grooves are formed on the surface of the fins.

[0006] When the fins are a continuous spiral structure along the outer surface of the tube body, the fins form multiple turns on the tube body surface, and the guide grooves between adjacent turns of the fins are arranged in a spiral structure.

[0007] When the fins are multiple parallel structures distributed axially along the outer surface of the tube, the guide grooves between adjacent fins are arranged in a spiral structure.

[0008] In one embodiment, the spacing between adjacent guide grooves on the fins is the same.

[0009] In one embodiment, the thickness of the fins gradually decreases in the direction away from the tube body.

[0010] In one embodiment, the axial spacing between adjacent fins is 0.4 to 0.9 mm.

[0011] In one embodiment, the thickness of the fin near the end of the tube 1 is 0.1 to 0.9 mm.

[0012] In one embodiment, the height of the fin is 0.2-0.7 mm.

[0013] The advantages or beneficial effects of the above technical solution include at least the following: opening multiple guide grooves on the fin surface of the tube body can increase the contact area of ​​the medium passing through the fins and guide the medium passing through, thereby increasing the contact time and improving the heat exchange efficiency; and arranging the guide grooves between adjacent fins in a spiral structure allows the medium guided by the guide grooves to pass through the adjacent guide grooves more smoothly, thereby further increasing the heat exchange efficiency.

[0025] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0026] See Figure 1 and Figure 2 The present invention provides a high-efficiency condenser tube with a guide groove, including a tube body 1 and a continuous spiral structure or multiple parallel fins 2 distributed circumferentially along the outer surface of the tube body 1. Multiple concave guide grooves 3 are formed on the surface of the fins 2.

[0027] When the fin 2 is a continuous spiral structure along the outer surface of the tube body 1, the fin 2 forms multiple circumferences on the surface of the tube body 1, and the guide grooves 3 between adjacent circumference fins 2 are arranged in a spiral structure.

[0028] When the fins 2 are multiple parallel structures distributed along the outer surface of the tube body 1, the guide grooves 3 between adjacent fins 2 are arranged in a spiral structure.

[0029] With the above structure, multiple guide grooves 3 are opened on the surface of the fins 2 on the tube body 1, which can increase the contact area of ​​the medium passing through the fins 2 and guide the medium passing through, thereby increasing the contact time and improving the heat exchange efficiency. Furthermore, the guide grooves 3 between adjacent fins 2 are arranged in a spiral structure, so that the medium guided by the guide grooves 3 can pass through the adjacent guide grooves 3 more smoothly, thereby further increasing the heat exchange efficiency.

[0030] In one embodiment, see Figure 1 and Figure 2The spacing between adjacent guide grooves 3 on fin 2 is the same. In practical applications, setting the spacing between adjacent guide grooves 3 on fin 2 to be the same can make each guide groove 3 arranged regularly, which is convenient for processing.

[0031] The thickness of fin 2 gradually decreases in the direction away from tube 1. In practical applications, by adjusting the thickness of fin 2, the surface area of ​​fin 2 can be increased, thereby increasing the contact area between fin 2 and the medium and improving heat exchange efficiency.

[0032] In one embodiment, see Figure 1 and Figure 2 The axial spacing between adjacent fins 2 is 0.4 to 0.9 mm.

[0033] The thickness of the fin 2 near the end of the tube 1 is 0.1 to 0.9 mm.

[0034] The height of fin 2 is 0.2-0.7mm.
