[0029] The following combines the accompanying drawings Figures 1 to 4 and further illustrates the technical solution of the present utility model through specific implementation manners.

[0030] As Figures 1-4 shown, a metal tube utilizing phase change energy storage includes a hollow tube body 1, a bottom plate 2, and a tube cap 3;

[0031] A column 31 is provided at the inner top end of the tube cap 3. A glue storage groove 32 is formed between the side wall of the column 31 and the inner side wall of the tube cap 3. The glue storage groove 32 is filled with sealant. An internal thread is provided on the inner side wall of one end of the tube cap 3, and an external thread is provided on the outer side wall of the tube body 1. The tube cap 3 is threadedly connected to the tube body 1 through the internal thread and the external thread.

[0032] The other end of the tube body 1 is connected to the bottom plate 2, and the bottom plate 2 is used to block the other end of the tube body 1.

[0033] The provided glue storage tank 32 can store a relatively large amount of sealant, enabling sufficient sealant to be filled at the connection between the tube cap 3 and the tube body 1. This results in a good sealing effect and can prevent the leakage of the phase change material from the connection between the tube cap 3 and the tube body 1.

[0034] As Figure 2 shown, one end of the tube body 1 is provided with a connection section 11. The connection section 11 is provided with an opening 12 communicating with the tube body 1, and the external thread is provided on the outer sidewall of the connection section 11.

[0035] Specifically, by providing the connection section 11 to connect with the tube cap 3, interference can be avoided when processing fins on the outer sidewall of the tube body 1.

[0036] As Figure 2 shown, the end of the connection section 11 away from the tube body 1 is in close contact with the inner top wall of the glue storage tank 32.

[0037] Specifically, the end of the connection section 11 away from the tube body 1 being in close contact with the inner top wall of the glue storage tank 32 can allow the connection section 11 to insert a sufficient length into the glue storage tank 32, thereby increasing the contact area between the connection section 11 and the sealant and making the connection between the connection section 11 and the tube cap 3 tighter, further improving the sealing effect.

[0038] As Figure 1 shown, the outer sidewall of the tube body 1 is a smooth surface.

[0039] Specifically, the outer sidewall of the tube body 1 being a smooth surface can facilitate the processing and forming of the tube body 1.

[0040] As Figures 3-4 shown, the sidewall of the tube body 1 is provided with a plurality of fins 13.

[0041] Specifically, by providing a plurality of fins 13, the contact area between the tube body 1 and the outside can be increased, thereby facilitating heat transfer.

[0042] As Figure 3 shown, the plurality of fins 13 surround the tube body 1 and are arranged at equal intervals along the axis of the tube body 1.

[0043] As Figure 4 shown, the plurality of fins 13 are arranged in a circular array around the axis of the tube body 1.

[0044] As Figures 1-4 shown, the tube body 1, the bottom plate 2, and the tube cap 3 are made of a metal material with high thermal conductivity.

[0045] Specifically, the tube body 1, the bottom plate 2 and the tube cover 3 are made of metal materials with high thermal conductivity, which can quickly transfer external heat to the phase change material. The phase change material absorbs heat from a solid to a liquid, thereby storing the heat. When the phase change material changes from a liquid to a solid, a large amount of heat is released, thereby quickly transferring the heat to the outside.

[0046] Preferably, the tube body 1, the bottom plate 2 and the tube cover 3 are made of stainless steel, which has a long service life. They can also be made of any one of aluminum, copper, steel and iron.

[0047] like Figure 2 As shown, the sealant is anaerobic curing glue or silicone.

[0048] Specifically, anaerobic curing adhesive and silicone have good high temperature resistance, corrosion resistance, waterproof and sealing properties, which can make the device have good service life and sealing performance.

[0049] like Figure 1 As shown, the outer side wall of the tube cover 3 is provided with anti-slip grooves.

[0050] Specifically, the anti-slip grooves can prevent the user from slipping when rotating the tube cover 3 .

[0051] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
