[0015] Reference Figure 1 and Figure 2 The utility model is further described.

[0016] A vacuum tube heat transfer aluminum fin comprises a heat absorbing tube 1, a heat transfer tube 2 and a plurality of heat-conducting fins 3. The diameter of the heat absorbing tube 1 is larger than the diameter of the heat transfer tube 2. The heat absorbing tube 1 is sleeved on the outside of the heat transfer tube 2 and is concentric. A first opening 4 is opened on one side of the heat absorbing tube 1, and a second opening 5 is opened on one side of the heat transfer tube 2. The first opening 4 and the second opening 5 face the same side. The heat-conducting fins 3 connect the inner wall of the heat absorbing tube 1 and the outer wall of the heat transfer tube 2. The plurality of heat-conducting fins 3 are all located on the side of the heat transfer tube 2 opposite to the opening. The wall thickness of the heat absorbing tube 1 and the heat transfer tube 2 and the thickness of the heat-conducting fins 3 are all 0.5 mm to 1 mm.

[0017] Preferably, in this embodiment, the wall thickness of the heat absorbing tube 1 and the heat transfer tube 2 and the thickness of the heat conducting fins 3 are all 0.5 mm.

[0018] like Figure 2 As shown, in this example, preferably, the heat absorbing tube 1 is provided with support plates 6 located on both sides of the first opening 4, and the support plates 6 face the inner side of the heat absorbing tube 1. The support plates 6 on both sides of the first opening 4 shrink the outer diameter of the heat absorbing tube 1 to facilitate insertion into the vacuum tube.

[0019] like Figure 2 As shown, in this example, preferably, the heat transfer tube 2 is provided with arc-shaped plates 7 located on both sides of the second opening 5, and the arc-shaped plates 7 face the outside of the heat transfer tube 2. The opening formed by the two arc-shaped plates 7 is larger than the second opening 5, which makes it convenient to insert the heat pipe into the heat transfer tube 2.

[0020] like Figure 2 As shown, in this embodiment, preferably, three heat-conducting fins 3 are provided, and the angles between two adjacent heat-conducting fins 3 are the same.

[0021] Specifically, the number of the heat-conducting fins 3 can be increased or decreased according to actual needs.

[0022] like Figure 2 As shown, in this embodiment, preferably, a V-shaped groove 8 is provided on the heat absorbing tube 1, and the V-shaped groove 8 is opposite to the first opening 4, and one of the heat conducting fins 3 connects the V-shaped groove 8 and the heat transfer tube 2, thereby improving the strength of the heat absorbing tube 1.

[0023] like Figure 1 and Figure 2 As shown, during installation, first insert the copper heat pipe 9 into the heat transfer tube 2 through the second opening 5 on the heat transfer tube 2, so that the inner wall of the heat transfer tube 2 is in close contact with the outer wall of the copper heat pipe 9, and then the vacuum tube is sleeved on the heat absorbing tube 1. When sleeved, the diameter of the heat absorbing tube 1 is reduced through the first opening 4 on the heat absorbing tube 1, so that it can be easily inserted into the vacuum tube. After it is fully inserted into the vacuum tube, the tube walls on both sides of the first opening 4 are released, so that the outer wall of the heat absorbing tube 1 is in close contact with the inner wall of the vacuum tube. Then, the end of the extended copper heat pipe 9 is connected to the water tank. During heating, the vacuum tube absorbs heat and transfers it to the heat absorbing tube 1, and the heat absorbing tube 1 then transfers the heat to the heat transfer tube 2 through a number of heat-conducting fins 3. The heat transfer tube 2 then transfers the heat to the copper heat pipe 9, thereby heating the water in the water tank.

[0024] By increasing the thickness of the heat absorbing tube 1, the heat transfer tube 2 and the heat-conducting fins 3, the strength of the entire structure is greatly improved, and it is not easy to deform during transportation and installation; the curved plate 7 on the second opening 5 forms a press-fit installation copper heat pipe 9, which can make the copper heat pipe 9 and the heat transfer tube 2 fit tightly, thereby improving the heat transfer efficiency; the first opening 4 makes the tube walls of the heat absorbing tube 1 on both sides elastic, and at the same time makes it fit tightly with the inner wall of the vacuum tube to improve the heat transfer efficiency. The multiple heat-conducting fins 3 accelerate the speed of heat transfer between the heat absorbing tube 1 and the heat transfer tube 2, and at the same time increase the strength of the entire structure.

[0025] Specifically, under the same conditions, in the same environment, and for the same time, the temperature of the copper heat pipe 9 installed with the new aluminum fins is 15%-25% higher than that of the copper heat pipe 9 installed with the traditional aluminum fins, greatly improving the heating efficiency of the water in the water tank.

[0026] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
