Description

Technical Field

[0001] This utility model belongs to the technical field of nozzle heat dissipation equipment, specifically referring to a high-flux heat transfer tube on the surface of a multi-metal nozzle. Background Technology

[0002] Metal nozzles are widely used in fluid jetting and atomization processes in many fields such as chemical engineering, energy, and aerospace. However, during operation, the surface of the metal nozzle exchanges heat with the high-temperature, high-speed fluid. Due to the limitations of traditional heat transfer tube design, the heat from the metal nozzle cannot be transferred quickly and effectively, which can easily lead to excessively high nozzle surface temperature. This can affect the nozzle's service life and performance, and may even cause safety accidents.

[0003] However, most existing heat transfer tubes have small heat transfer areas and poor heat flow disturbance, which cannot meet the requirements of metal nozzles for high-throughput heat transfer. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model proposes a high-flux heat transfer tube on the surface of a multi-metal nozzle, which effectively solves the problems that most heat transfer tubes have small heat transfer area, poor heat flow disturbance effect, and cannot meet the requirements of metal nozzles for high-flux heat transfer.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a high-flux heat transfer tube for the surface of a multi-metal nozzle, which includes a metal nozzle body and a heat transfer structure. The heat transfer structure is disposed on the metal nozzle body and includes a surface heat dissipation unit and a flow heat dissipation unit. The surface heat dissipation unit is disposed on the metal nozzle body and the flow heat dissipation unit is disposed on the outer side of the surface heat dissipation unit.

[0006] The surface heat dissipation unit includes a heat-conducting plate, a heat transfer tube body, fixing bolts, fins, and a flow guiding channel. The heat-conducting plate is fixedly disposed on the outside of the metal nozzle body and arranged in eight groups. The heat transfer tube body is fixed to the heat-conducting plate by fixing bolts. The fins are fixedly disposed on the outer wall of the heat transfer tube body and the flow guiding channel is disposed on the inner wall of the heat transfer tube body.

[0007] Preferably, the flow heat dissipation unit includes a heat dissipation channel, a heat dissipation pipe, and a suction machine. The heat dissipation channel is fixedly disposed on the upper end of the heat transfer pipe body and communicates with the hole of the heat transfer pipe body. The heat dissipation pipe is fixedly disposed on the outer wall of the heat dissipation channel and communicates with the internal channel of the heat dissipation channel. The suction machine is connected to the air outlet at one end of the heat dissipation pipe.

[0008] To increase the heat dissipation area, the fins are parallel to the axis of the heat transfer tube, have a sheet-like structure, and are spaced 30 degrees apart from each other.

[0009] To achieve faster gas flow, an air inlet is provided at the bottom of the heat transfer tube, and the internal flow channel of the heat transfer tube is spiral-shaped. The flow channel increases the residence time of the fluid in the heat transfer tube, enhances the turbulence of the fluid, disrupts the fluid boundary, and improves the heat transfer efficiency.

[0010] Furthermore, a connecting flange is provided at the bottom of the heat transfer tube body, and multiple evenly distributed bolt holes are opened on the connecting flange. The flange is connected to the mounting holes of the heat-conducting plate on the metal nozzle body by fixing bolts, so as to ensure a tight connection and good heat transfer contact between the heat transfer tube body and the metal nozzle body.

[0011] To increase the flow rate, the heat dissipation channel connects multiple sets of heat transfer tubes, and the hot airflow converges and is discharged through the heat dissipation tubes.

[0012] The beneficial effects of this utility model using the above structure are as follows: The high-flux heat transfer tube with a multi-metal nozzle surface proposed in this solution increases the heat dissipation area and improves the heat dissipation efficiency by setting fixing bolts and fins on the heat transfer tube body. At the same time, when the suction machine is suctioning, the airflow inside the heat transfer tube body accelerates and quickly carries away the heat, thus meeting the high-flux heat transfer requirements.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a high-flux heat transfer tube for the surface of a multi-metal nozzle, comprising a metal nozzle body 1 and a heat transfer structure 2. The heat transfer structure 2 is disposed on the metal nozzle body 1 and includes a surface heat dissipation unit 3 and a flow heat dissipation unit 4. The surface heat dissipation unit 3 is disposed on the metal nozzle body 1 and the flow heat dissipation unit 4 is disposed on the outer side of the surface heat dissipation unit 3.

[0021] The surface heat dissipation unit 3 includes a heat-conducting plate 5, a heat transfer tube body 6, fixing bolts 7, fins 8, and a flow guiding channel 9. The heat-conducting plate 5 is fixedly disposed on the outside of the metal nozzle body 1 and arranged in eight groups. The heat transfer tube body 6 is fixed to the heat-conducting plate 5 by fixing bolts 7. A connecting flange is provided at the bottom of the heat transfer tube body 6. The connecting flange has multiple evenly distributed bolt holes. The fixing bolts 7 are used to connect the heat transfer tube body 6 to the mounting holes of the heat-conducting plate 5 on the metal nozzle body 1, ensuring a tight connection and good heat transfer contact between the heat transfer tube body 6 and the metal nozzle body 1. The fins 8 are fixed on the outer wall of the heat transfer tube body 6. The fins 8 are parallel to the axial direction of the heat transfer tube body 6 and have a sheet-like structure with a 30-degree interval between adjacent fins 8. The flow guiding channel 9 is provided on the inner wall of the heat transfer tube body 6. An air inlet is provided at the bottom of the heat transfer tube body 6. The flow guiding channel 9 inside the heat transfer tube body 6 is spiral. The flow guiding channel 9 increases the residence time of the fluid in the heat transfer tube body 6, enhances the turbulence of the fluid, breaks the fluid boundary, and improves the heat transfer efficiency.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the flow heat dissipation unit 4 includes a heat dissipation channel 10, a heat dissipation pipe 11, and a suction machine 12. The heat dissipation channel 10 is fixedly installed on the upper end of the heat transfer pipe body 6 and communicates with the hole of the heat transfer pipe body 6. The heat dissipation pipe 11 is fixedly installed on the outer wall of the heat dissipation channel 10 and communicates with the internal channel of the heat dissipation channel 10. The heat dissipation channel 10 connects multiple sets of heat transfer pipe bodies 6. Hot air flows through the heat dissipation pipe 11 and is discharged. The suction machine 12 is connected to the air outlet at one end of the heat dissipation pipe 11.

[0023] In practical use, when the metal nozzle body 1 is spraying, it generates a large amount of heat. At this time, the temperature of the metal nozzle body 1 rises, and the heat of the metal nozzle body 1 is conducted to the heat transfer tube body 6 through the heat conduction plate 5. At this time, the outer fins 8 of the heat transfer tube body 6 dissipate heat outward, and the suction machine 12 draws in the gas. At this time, the gas enters the heat transfer tube body 6 through the air inlet at the bottom of the heat transfer tube body 6. At this time, the gas is trapped in the flow channel 9 inside the heat transfer tube body 6, which increases the heat transfer and carries away more heat. The heat enters the heat dissipation channel 10 with the gas, gathers in the heat dissipation pipe 11, and is discharged through the suction machine 12, thereby improving the heat dissipation effect. The above is the entire process of using the high-throughput heat transfer tube on the surface of the multi-metal nozzle.
