[0030] Example 1

[0031] Please see Figure 1This invention provides a technical solution: a titanium alloy tube with a pressure-resistant structure, comprising a titanium alloy tube body 1, a pressure-resistant and stress-relief groove 2 formed on the outer circumference of the titanium alloy tube body 1; a pressure-resistant compensation ring 3 formed on the inner circumference of the titanium alloy tube body 1; a heat-conducting pipe 10 inserted into the surface of the pressure-resistant and stress-relief groove 2, and the heat-conducting pipe 10 passing through the pressure-resistant compensation ring 3; the pressure-resistant and stress-relief groove 2 formed on the outer circumference of the titanium alloy tube body 1 and the pressure-resistant compensation ring 3 formed on the inner circumference of the titanium alloy tube body 1 constitute the pressure-resistant structure of the titanium alloy tube body 1, and multiple sets of heat-conducting pipes 10 are inserted into the surface of the pressure-resistant and stress-relief groove 2 to conduct heat into the interior of the titanium alloy tube body 1, thereby improving the pressure resistance of the titanium alloy tube body 1 and improving the heat dissipation effect of the titanium alloy tube body 1.

[0032] Example 2

[0033] See attached document Figure 2 Based on Example 1, in order to achieve strength compensation for the titanium alloy tube 1 after opening the pressure relief groove 2, the pressure relief groove 2 is an annular groove, and multiple pressure relief grooves 2 are provided. The multiple pressure relief grooves 2 are arranged at equal distances and of equal size along the long side of the titanium alloy tube 1. Both side walls of the pressure relief groove 2 are inclined. The pressure compensation ring 3 is an annular plate structure. The outer ring surface of the pressure compensation ring 3 is fixed on the inner ring surface of the titanium alloy tube 1. The pressure compensation ring 3 and the titanium alloy tube 1 correspond one-to-one. A flow guide ring 4 is sleeved on the outside of the pressure compensation ring 3. The flow guide ring 4 is an annular structure with a circular arc cross section. The pressure compensation ring 3 is located in the outer ring groove of the flow guide ring 4. The flow guide ring 4 is fixed on the inner ring surface of the titanium alloy tube 1.

[0034] The opening of the pressure relief groove 2 causes the pressure of the downward-pressing titanium alloy tube 1 to be interrupted, and the pressure relief compensation ring 3 is installed on the inner ring surface of the titanium alloy tube 1 to compensate for the hidden danger caused by the reduction of the wall thickness of the titanium alloy tube 1 due to the opening of the pressure relief groove 2. Furthermore, the outer side of the pressure relief compensation ring 3 is fitted with a guide ring 4 to strengthen the pressure resistance of the titanium alloy tube 1 in the part where the pressure relief groove 2 is opened.

[0035] Example 3

[0036] See attached document Figure 3 and Figure 4 Based on Embodiment 2, in order to achieve heat dissipation from the inside of the titanium alloy tube 1 to the heat pipe 10, a silicone heat-conducting ring 5 is provided on the inner ring surface of the flow guide ring 4. Both the flow guide ring 4 and the silicone heat-conducting ring 5 have reserved perforations on their surfaces. A silicone sleeve 12 is inserted into the reserved perforations. The silicone sleeve 12 is fixed on the inner ring surface of the pressure compensation ring 3, and one end of the heat pipe 10 is inserted into the silicone sleeve 12. A heat dissipation fin ring 11 is provided on the outer side of the tube body of the heat pipe 10. Multiple heat dissipation fin rings 11 are provided. Multiple heat dissipation fin rings 11 are arranged at equal distances and of equal size along the heat pipe 10. The heat dissipation fin ring 11 has a ring structure with a circular arc cross-section.

[0037] When the fluid inside the titanium alloy tube 1 flows over the inner ring surface of the guide ring 4, the silicone heat-conducting ring 5 absorbs heat, and the silicone sheath 12 wraps around the bottom of the heat-conducting tube 10 to prevent the fluid from entering the guide ring 4. The heat-conducting tube 10 transports heat outward and dissipates heat through multiple heat dissipation fins 11. The special shape of the heat dissipation fins 11 increases the heat dissipation area.

[0038] Example 4

[0039] Based on Example 3, in order to improve the compressive strength of the titanium alloy tube 1, two compressive rings 7 are arranged side by side on the surface of the compressive stress relief groove 2. The compressive rings 7 have a U-shaped cross section and a ring structure. Multiple connecting rings 8 are arranged between the two compressive rings 7. The ring diameters of the multiple connecting rings 8 are different. The other end of the heat conduction pipe 10 is fixed to the inner wall of the compressive ring 7. Multiple heat dissipation holes 9 are opened on the side plate of the compressive ring 7. The cross strut 6 has a cross-shaped rod structure. The end of the cross strut 6 passes through the flow guide ring 4 and the silicone heat conduction ring 5 and is fixed to the inner ring surface of the compressive compensation ring 3.

[0040] Two sets of anti-compression rings 7 form anti-compression ribs in the anti-compression relief groove 2, and the anti-compression rings 7 are ring frames, that is, the two side plates of the anti-compression rings 7 are anti-compression rib structures, and the two sets of anti-compression rings 7 form four sets of anti-compression rib structures.
