[0022] Other objects and advantages of the present invention will become apparent through explanation of the following preferred embodiments of the present application.

[0023] Example 1

[0024] like Figure 1As shown, a spiral cooling device includes a compression cylinder 1 and an outer sleeve 2 arranged on the outside of the compression cylinder 1, and an annular cavity 3 for circulating circulating water is formed between the compression cylinder 1 and the outer sleeve 2; a circulating water inlet 4 is provided at one end of the annular cavity 3, and a circulating water outlet 5 is provided at the other end.

[0025] like Figures 2 to 4 As shown, the spiral cooling device further comprises a spiral heat dissipation sleeve 6 , which comprises a cylindrical sleeve body 61 and spiral sheets 62 spirally arranged around the outer contour of the sleeve body 61 .

[0026] The inner contour of the sleeve 61 fits with the outer contour of the compression cylinder 1, and the outer contour of the spiral blade 62 fits with the inner contour of the outer sleeve 2, thereby forming a spiral circulating water flow path in the annular cavity 3. The formation of the spiral circulating water flow path improves the uniformity of the distribution of the circulating water in the annular cavity 3. In addition, the compression cylinder 1 conducts heat to the sleeve 61 and the spiral blade 62, thereby increasing the heat exchange area.

[0027] In this embodiment, the sleeve 61 can be installed on the outer side of the compression cylinder 1 by means of interference fit, which can improve the heat transfer efficiency between the sleeve 61 and the compression cylinder 1 .

[0028] In some embodiments, the outer contour of the spiral piece 62 is provided with a sealing groove 623 extending spirally along the outer surface of the spiral piece 62, and a sealing strip 7 is provided in the sealing groove 623. The sealing strip 7 is used to form a sealed connection at the connection between the outer end of the spiral piece 62 and the inner contour of the outer sleeve 2.

[0029] Furthermore, the cross section of the sealing groove 623 is rectangular, which is convenient for filling the sealing strip 7 to form a sealed connection between the spiral sheet 62 and the outer sleeve 2.

[0030] Furthermore, the spiral sheet 62 has a starting end 621 and a terminating end 622, and the starting end 621 and the terminating end 622 have an angle along the circumferential direction of the sleeve 61. Thus, the spiral heat dissipation sleeve 6 adjusts the arrangement of the circulating water in the annular cavity 3 along the circumferential direction, and also improves the uniformity of the circulating water flowing in the annular cavity 3. The angle can be, for example, 180°, and the circulating water can be guided from the annular cavity 3 on the upper side of the compression cylinder 1 to the annular cavity 3 on the lower side of the compression cylinder 1.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the inner contour of the sleeve body 61 is provided with an internal thread portion 611; the outer contour of the compression cylinder 1 is provided with an external thread matching the internal thread portion 611. The spiral heat dissipation sleeve 6 and the compression cylinder 1 are connected by threads, which increases the contact area between the spiral heat dissipation sleeve 6 and the compression cylinder 1, thereby improving the heat transfer efficiency.

[0033] Example 3

[0034] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that there are multiple spiral heat dissipation sleeves 6, and the multiple spiral heat dissipation sleeves 6 are arranged along the axial direction of the compression cylinder 1, thereby further improving the heat exchange efficiency.

[0035] Example 4

[0036] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the spiral heat dissipation sleeve 6 is rotatably connected to the compression cylinder 1. For example, a bearing 8 can be installed between the spiral heat dissipation sleeve 6 and the compression cylinder 1. For example, a needle bearing 8 can be used. In addition, sealing rings can be provided at both ends of the heat dissipation sleeve to prevent the circulating water from corroding the bearing 8.

[0037] The spiral heat dissipation sleeve 6 is rotatably connected to the outer sleeve 2. For example, a small gap can be reserved between the outer edge of the spiral heat dissipation sleeve 6 and the inner contour of the outer sleeve 2 to facilitate the rotation of the spiral heat dissipation sleeve 6. A small amount of water passes through the gap, which has little effect on the uniform distribution of circulating water.

[0038] The flow of circulating water drives the spiral heat dissipation sleeve 6 to rotate around the compression cylinder 1, which is beneficial to the uniform distribution of the circulating water in the circumferential direction of the annular cavity 3, thereby improving the heat exchange efficiency.
