Technical Field

[0001] The utility model relates to a heat exchange metal special-shaped tube, in particular to a heat exchange metal special-shaped tube, belonging to the technical field of heat exchange tubes. Background Art

[0002] Heat exchange metal tubes are the core components of heat exchangers. Their main function is to transfer heat between two or more fluids without allowing these fluids to mix directly. Heat exchange is carried out through the metal tube wall. The high-temperature fluid releases heat and the low-temperature fluid absorbs heat, thereby achieving heat transfer and balance.

[0003] However, at present, the heat exchange tubes in traditional heat exchangers usually use round tubes or oval tubes for heat exchange, the inner walls of which are relatively smooth, and the heat exchange contact area per unit volume is small, which affects the heat exchange efficiency.

[0004] To this end, we provide a heat exchange metal special-shaped tube to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The heat exchange metal special-shaped tube designs the medium channel in the tube body into a wave groove shape, which not only enhances the disturbance of the medium and extends the flow path, but also increases the heat exchange area of ​​the device per unit volume due to the design of the wave groove, thereby significantly improving the heat exchange efficiency.

[0017] 2. The heat exchange metal special-shaped tube is equipped with an exhaust bottle. The bolt rod is adjusted downward so that the floating block has space to move in the exhaust bottle, so that the gas can be discharged from the device through the exhaust elbow.

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] See also Figure 1 、 Figure 3 , including a tube body 1, a wave groove 2 is opened in the tube body 1, the cross section of the wave groove 2 is wavy, and continuous grooves are formed between the wave crests and troughs of the wave shape, so that when the heat exchange medium flows in the wave groove 2, it can be continuously disturbed, and the wavy design can extend the flow path, thereby improving the heat exchange efficiency.

[0025] See also Figure 1 、 Figure 2 、 Figure 3 One side of the tube body 1 is set as an inlet 3, and the other side is set as an outlet 4. The heat exchange medium enters the wave groove 2 from the inlet 3 and is then discharged from the outlet 4. The inner walls of the wave groove 2, the inlet 3, and the outlet 4 are connected with internal auxiliary strips 5. The cross-section of the internal auxiliary strips 5 is tooth-shaped. The internal auxiliary strips 5 are evenly distributed in the wave groove 2. The internal auxiliary strips 5 are used to increase the contact area between the heat exchange medium and the tube body 1, thereby increasing the heat exchange contact area of ​​the device, thereby improving the heat exchange efficiency. The tube body 1 and the internal auxiliary strips 5 are made of the same material, both of which are metals with good thermal conductivity such as copper, aluminum or stainless steel. The use of metal materials with good thermal conductivity ensures good thermal conductivity and further improves the heat exchange efficiency.

[0026] Please refer again Figure 1 、 Figure 3 The side end of the inlet 3 is connected to a tightening tube 6, which is funnel-shaped, with a large opening radius on one side and a small opening radius on the other side. The end with a small opening radius is connected to the inlet 3. When the heat exchange medium enters the pipe body 1 through the tightening tube 6, the design of the tightening tube 6 can change the flow state of the fluid in the pipe body 1 and increase the turbulence of the fluid in the inlet 3 section of the pipe body 1. Turbulence is conducive to heat transfer because it can increase the contact area and heat transfer coefficient between the fluid and the pipe wall, thereby improving the heat exchange efficiency. Especially when the flow rate is low, the effect of the tightening tube 6 is more obvious.

[0027] The upper end of the tightening tube 6 is connected to an exhaust bottle 7, which is used to discharge the gas in the tube body 1. When there is gas inside the heat exchange tube, the gas will form a thermal resistance layer, which hinders the effective transfer of heat between the liquids. This is because the thermal conductivity of the gas is much lower than that of the liquid and the metal pipe, which causes the heat transfer process to be blocked. By discharging the gas, this thermal resistance layer can be eliminated, so that heat can be transferred more smoothly, thereby improving the heat exchange efficiency of the device.

[0028] Please refer again Figure 4 The exhaust bottle 7 is connected to the tightening tube 6, and the connection point is the air inlet 8. The gas in the tube body 1 enters the exhaust bottle 7 through the air inlet 8. The upper end of the exhaust bottle 7 is connected with an exhaust elbow 9. The exhaust elbow 9 is used to discharge the gas in the exhaust bottle 7. A floating block 10 is slidably connected inside the exhaust bottle 7. The floating block 10 has a low density and can float on the surface of the liquid medium. A plug 11 is connected to the upper end of the floating block 10, and the plug 11 can be inserted into the exhaust elbow 9. When the plug 11 is inserted into the exhaust elbow 9, the exhaust elbow 9 will be closed. A vent 12 is opened in the floating block 10, and the vent 12 vertically penetrates the floating block 10 completely, so that the gas can reach the upper end of the floating block 10 through the vent 12.

[0029] The upper end of the exhaust bottle 7 is connected to a support ring 13, and a threaded groove is provided in the support ring 13. A bolt rod 14 is connected to the inner thread of the support ring 13. Rotating the bolt rod 14 can make it move up and down in the support ring 13. The upper end of the bolt rod 14 is connected to a bolt head, and the lower end of the bolt rod 14 is connected to a guide rod 15. The guide rod 15 is inserted into the exhaust bottle 7. The guide rod 15 is located in the floating block 10. The two are slidably connected, so that the floating block 10 can be constrained so that it can only move up and down but cannot tilt. A tight seal is provided at the connection between the exhaust bottle 7 and the guide rod 15. The sealing ring 16 prevents the gas from overflowing from the connection gap between the exhaust bottle 7 and the guide rod 15. The lower end of the guide rod 15 is connected to a support plate 17, which is located at the lower end of the floating block 10. When the exhaust bottle 7 is not needed to exhaust, the bolt rod 14 is rotated to move it upward, so that the guide rod 15 can drive the support plate 17 to move. The support plate 17 will be able to lift the floating block 10, so that the upper end of the floating block 10 is in close contact with the sealing ring 16, so that the plug 11 can be inserted into the exhaust elbow 9. At this time, the exhaust bottle 7 will be completely closed and the internal and external gases will not be able to circulate.

[0030] When the utility model is in use, the heat exchange medium enters the inlet 3 of the tube body 1 from the tightening tube 6, and then flows into the wave groove 2. The heat exchange medium flows in the wave groove 2 and contacts with the inner auxiliary strip 5, so that heat exchange can be performed. The design of the wave groove 2 and the inner auxiliary strip 5 not only enhances the disturbance of the fluid and extends the flow path, but also increases the heat exchange contact area, which can significantly improve the heat exchange efficiency. During this period, the gas in the tube body 1 can be discharged from the device through the exhaust bottle 7. Specifically, by rotating the bolt rod 14 to make it interact with the support ring 13, the bolt rod 14 and the guide ring 13 can be made to rotate. The rod 15 and the support plate 17 move downward, so that the floating block 10 can move in the exhaust bottle 7. Since the density of the gas is small, it has buoyancy in the liquid, so the gas will enter the exhaust bottle 7 through the air inlet 8, and then reach the upper end of the floating block 10 through the air vent 12. Due to pressure reasons, the liquid medium will rise in the exhaust bottle 7, thereby enabling the floating block 10 to rise, so that the gas at its upper end can be squeezed and discharged into the exhaust elbow 9, thereby discharging the device. When the plug 11 is inserted into the exhaust elbow 9, the exhaust bottle 7 is sealed at this time, so that the liquid medium will not overflow.
