Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting through pipes, and more specifically to a heat-conducting copper pipe with spiral fins. Background Art

[0002] In the fields of refrigeration and heating: Heat-conducting copper pipes are widely used in the fields of refrigeration and heating, such as refrigerators and heaters, etc. Heat-conducting copper pipes have good heat-conducting performance and corrosion resistance, which makes them an indispensable material in the refrigeration and heating processes. In order to increase the heat dissipation of the heat-conducting copper pipes, spiral heat-dissipating fins are arranged at equal intervals on the surface of some heat-dissipating copper pipes to increase the contact area with air. During use, the heat-dissipating fins are directly welded to the outside of the copper pipe. When the heat-dissipating fins are bent or damaged, due to the reason of subsequent welding, the replacement is not convenient enough. Moreover, the fins and the copper pipe are connected by welding. In the vicinity of the welding area, the contents of elements such as carbon, sulfur, and manganese may change greatly, resulting in the chemical composition of the weld being different from that of the base material. Therefore, the welding area will show hardness and toughness characteristics different from those of the base material, which will affect the overall mechanical properties of the steel. Therefore, it is urgent to design a heat-conducting copper pipe with spiral fins. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a heat-conducting copper pipe with spiral fins to solve the problems existing in the above-mentioned background art.

[0004] The utility model provides the following technical solution: A heat-conducting copper pipe with spiral fins, including a device body. The device body includes a heat-conducting copper pipe main body. An fin assembly is arranged on the outer side of the heat-conducting copper pipe main body. The fin assembly includes a first arc-shaped sleeve. The first arc-shaped sleeve is sleeved on the outside of the heat-conducting copper pipe main body. A second arc-shaped sleeve is arranged on the other side of the first arc-shaped sleeve. The second arc-shaped sleeve and the first arc-shaped sleeve are attached to the outside of the heat-conducting copper pipe main body. Semi-circular fins are fixedly installed at equal intervals on the outer sides of the first arc-shaped sleeve and the second arc-shaped sleeve. Fixed frames are fixedly installed on the outer sides of the ends of the first arc-shaped sleeve and the second arc-shaped sleeve. The fixed frames on the first arc-shaped sleeve and the second arc-shaped sleeve are locked by screws and nuts. By disassembling the screws and nuts on the first arc-shaped sleeve and the second arc-shaped sleeve, the first arc-shaped sleeve and the second arc-shaped sleeve can be disassembled from the outside of the heat-conducting copper pipe main body. In this way, the situation of being unable to disassemble caused by the welding connection method and the influence on the welding area outside the heat-conducting copper pipe main body is avoided.

[0005] Further, blocking rings are fixedly installed on the outer sides of both ends of the heat-conducting copper pipe main body. The blocking rings are abutted against the first arc-shaped sleeve and the second arc-shaped sleeve, which increases the stability of the first arc-shaped sleeve and the second arc-shaped sleeve after connection on the outside of the heat-conducting copper pipe main body.

[0006] Further, heat dissipation grooves are equidistantly formed on the outer surfaces of the semi-circular fins, and the cross-sections of the heat dissipation grooves are all hemispherical in shape, which increases the contact area between the semi-circular fins and the air and improves the heat dissipation efficiency.

[0007] Further, the number of fixing brackets at both ends of the first arc-shaped sleeve and the second arc-shaped sleeve is at least one, which increases the connection stability and strength of the first arc-shaped sleeve and the second arc-shaped sleeve.

[0008] Further, a plug rod is fixedly installed on the outer side of the fixing bracket on the first arc-shaped sleeve, and a card slot for clamping the plug rod is formed on the outer surface of the fixing bracket on the second arc-shaped sleeve. When alignment is convenient, the plug rod is inserted into the card slot, which facilitates the alignment of the first arc-shaped sleeve and the second arc-shaped sleeve.

[0009] Further, arc-shaped pieces are fixedly installed at the ends of the semi-circular fins away from the first arc-shaped sleeve and the second arc-shaped sleeve, and the materials of the arc-shaped pieces are all metals. The arc-shaped pieces wrap and protect the ends of the semi-circular fins, avoiding the deformation and damage of the exposed semi-circular fins.

[0010] Technical effects and advantages of the present utility model:

[0011] 1. By providing a fin assembly, the present utility model adopts this design to bring the disassembly of the screws and nuts on the first arc-shaped sleeve and the second arc-shaped sleeve, and the first arc-shaped sleeve and the second arc-shaped sleeve can be disassembled from the outside of the main body of the heat-conducting copper tube. In this way, the situation that the welding connection method cannot be disassembled and the welding area outside the main body of the heat-conducting copper tube is easily affected is avoided.

[0012] 2. When the first arc-shaped sleeve and the second arc-shaped sleeve are aligned, the plug rod on the outer side of the fixing bracket on the first arc-shaped sleeve is clamped in the card slot on the outer side of the fixing bracket on the second arc-shaped sleeve, realizing the alignment between the first arc-shaped sleeve and the second arc-shaped sleeve, which is convenient for locking and connecting through screws and nuts. The arc-shaped pieces wrap and protect the ends of the semi-circular fins, avoiding the hidden dangers of the directly exposed semi-circular fins. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example 1: Refer to Figures 1-4 , the present utility model provides a heat-conducting copper tube with spiral fins, including a device body 100. The device body 100 includes a main body 110 of the heat-conducting copper tube. A fin assembly 200 is provided on the outer side of the main body 110 of the heat-conducting copper tube. The fin assembly 200 includes a first arc-shaped sleeve 210. The first arc-shaped sleeve 210 is arranged outside the main body 110 of the heat-conducting copper tube. A second arc-shaped sleeve 211 is provided on the other side of the first arc-shaped sleeve 210. The second arc-shaped sleeve 211 and the first arc-shaped sleeve 210 are in contact with the outer side of the main body 110 of the heat-conducting copper tube. Semi-circular fins 212 are fixedly installed at equal intervals on the outer sides of the first arc-shaped sleeve 210 and the second arc-shaped sleeve 211. Fixing brackets 214 are fixedly installed on the outer sides of the ends of the first arc-shaped sleeve 210 and the second arc-shaped sleeve 211. The fixing brackets 214 on the first arc-shaped sleeve 210 and the second arc-shaped sleeve 211 are locked by screws and nuts. Blocking rings 215 are fixedly installed on the outer sides of both ends of the main body 110 of the heat-conducting copper tube. The blocking rings 215 are in contact with the first arc-shaped sleeve 210 and the second arc-shaped sleeve 211. Heat dissipation grooves 213 are provided at equal intervals on the outer surfaces of the semi-circular fins 212. The cross-sections of the heat dissipation grooves 213 are all hemispherical. The number of the fixing brackets 214 at both ends of the first arc-shaped sleeve 210 and the second arc-shaped sleeve 211 is at least one.

[0020] The working principle of the first embodiment of the present utility model: When in use, the heat on the outer surface of the main body 110 of the heat-conducting copper tube is dissipated through the first arc-shaped sleeve 210, the second arc-shaped sleeve 211 and the semi-circular fins 212, increasing the contact area between the device body 100 and the air and improving the heat dissipation efficiency. Remove the nuts on the screws passing through the fixing brackets 214, and remove the screws and nuts from the fixing brackets 214, then the first arc-shaped sleeve 210 and the second arc-shaped sleeve 211 can be separated for replacement.
