For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Below is the attached figure Figures 1 to 3 The technical solution of the utility model is further illustrated by specific implementation methods.

[0029] like Figure 1-3 As shown, a metal ball utilizing phase change energy storage comprises a ball body 1 and a sealing member 2;

[0030] The sphere 1 has a accommodating cavity 11, which is filled with a phase change material. The top of the sphere 1 is provided with an injection hole connected to the accommodating cavity 11. The seal 2 is detachably installed on the injection hole. The seal 2 fits tightly with the injection hole. The seal 2 is provided with a glue storage groove 24, which is filled with sealant. The sealant is connected between the sphere 1 and the seal 2.

[0031] The solution can store more sealant by setting up the glue storage tank 24, so that a sufficient amount of sealant can be filled between the ball 1 and the seal 2, and the seal 2 is tightly fitted with the injection hole to seal, which has a good sealing effect and can avoid leakage of the phase change material.

[0032] like Figure 3 As shown, the sealing member 2 includes a sealing cover 21, a threaded column 22 is connected to the middle of the bottom end of the sealing cover 21, the edge of the sealing cover 21 extends downward to form a first connecting sleeve 23, and the glue storage groove 24 is formed between the first connecting sleeve 23 and the threaded column 22;

[0033] The edge of the injection hole extends downward into the accommodating cavity 11 to form a second connecting sleeve 12 . The inner side wall of the second connecting sleeve 12 is provided with an internal thread matched with the threaded column 22 . The threaded column 22 is threadedly connected in the second connecting sleeve 12 .

[0034] Specifically, the phase change material is filled and stored in the accommodating cavity 11 of the sphere 1 through the injection hole in a molten liquid state. When the filling is completed and the injection hole needs to be sealed, the sealant is filled into the glue storage tank 24, and then the threaded column 22 is threadedly installed in the second connecting sleeve 12 until the sphere 1 blocks the glue storage tank 24. At this time, the sealant in the glue storage tank 24 connects the sphere 1 and the sealing member 2 together.

[0035] like Figure 3 As shown, at least one rib 25 is provided at the bottom end of the sealing cover 21 , and the rib 25 is located in the glue storage groove 24 .

[0036] Specifically, the contact area between the sealing cover 21 and the sealant can be increased by providing the convex rib 25, so that the sealing cover 21 and the sphere 1 are more tightly connected, further improving the sealing effect.

[0037] like Figure 3 As shown, the rib 25 is circular or elliptical.

[0038] Specifically, the circular or elliptical convex rib 25 can increase the contact area between the sealing cover 21 and the sealant, and the circular or elliptical convex rib 25 can facilitate the processing of the convex rib 25 .

[0039] like Figure 3 As shown, a first sinking groove 13 is formed at the top of the sphere 1 , and the bottom surface of the first connecting sleeve 23 is tightly fitted with the inner bottom surface of the first sinking groove 13 .

[0040] Specifically, since the outer surface of the sphere 1 is arc-shaped, the first sink 13 can facilitate the bottom surface of the first connecting sleeve 23 and the inner bottom surface of the first sink 13 to fit closely together to seal the glue storage tank 24.

[0041] Preferably, the inner bottom surface of the first sink 13 is a plane, and the bottom surface of the first connecting sleeve 23 is a plane.

[0042] like Figure 3 As shown, the sealing cover 21 and the threaded column 22 are an integrally formed structure, and the sealing cover 21 is made of plastic material.

[0043] Specifically, the sealing cover 21 and the threaded column 22 are an integrally formed structure, which can facilitate the processing of the sealing member 2 .

[0044] like Figure 3 As shown, the height at the bottom end of the rib 25 is higher than the height at the bottom end of the first connecting sleeve 23 .

[0045] Specifically, this structure can prevent the convex rib from interfering with the close fit between the bottom surface of the first connecting sleeve 23 and the inner bottom surface of the first sink 13 .

[0046] like Figure 1-2 As shown, a second sink groove 211 is provided at the middle of the top end of the sealing cover 21 , and the second sink groove 211 is in a cross shape or a regular hexagon.

[0047] Specifically, the second sink groove 211 in a cross shape or a regular hexagonal shape can facilitate the user to rotate the sealing cover 21 with the help of a tool.

[0048] like Figure 1-3 As shown, the sealant is anaerobic curing glue or silicone.

[0049] Specifically, the anaerobic curing adhesive and the silica gel have good high temperature resistance, corrosion resistance, waterproofness and sealing performance, which can make the device have a good service life and sealing performance.

[0050] like Figure 1-3 As shown, the sphere 1 is made of a metal material with high thermal conductivity.

[0051] Specifically, the sphere 1 is made of a metal material with high thermal conductivity, and can quickly transfer external heat to the phase change material through the sphere 1. The phase change material absorbs heat from a solid and changes into 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 through the sphere 1.

[0052] 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.
