Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation copper tubes, in particular to a rib-reinforced double-pass heat dissipation copper tube. Background Art

[0002] In the inverter's heat dissipation system, heat pipes are key heat dissipation components, and their fixing method is crucial to the heat dissipation effect and system stability. Mechanical clamp fixing is one of the commonly used heat pipe fixing methods. It connects the clamp to the power device housing or heat sink to achieve a stable installation of the heat pipe; however, this fixing method has some problems.

[0003] In the inverter cooling system, on the one hand, the clamping force is difficult to control accurately. During the operation of the inverter, factors such as vibration and thermal expansion cause unstable clamping force, which can easily cause local extrusion and deformation of the heat pipe. The thin-walled metal tube and the internal liquid absorption core structure are fragile and have a high risk of damage. In addition, there is a lack of effective monitoring methods. Operators tighten the bolts based on experience and cannot monitor the clamping force in real time.

[0004] On the other hand, in a high-temperature environment, the internal working fluid of the heat pipe vaporizes due to the high temperature, causing the pressure inside the tube to rise sharply, which may cause the heat pipe to rupture. At the same time, high temperature causes the material performance to deteriorate and the thermal conductivity to decrease. Currently, there is a lack of effective prevention and control measures for these problems, and improvements are urgently needed to improve the heat dissipation efficiency and stability of the inverter heat pipe.

[0005] Therefore, the present invention proposes a rib-enhanced double-pass heat dissipation copper tube to solve the above problems. Summary of the invention

[0021] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0022] Example: Please refer to Figures 1 to 6 , Figure 8 As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a rib-reinforced double-pass heat dissipation copper tube, including: a heat dissipation metal tube 1, and also including: a stable pressure-resistant component 6 and a heat dissipation auxiliary component 7, the heat dissipation auxiliary component 7 is arranged in the stable pressure-resistant component 6; The stable pressure-resistant component 6 is used to reduce the deformation damage to the heat dissipation metal tube 1 caused by the fastening force when the heat dissipation metal tube 1 is installed on the power device or heat sink using a clamp; the outer surface of the heat dissipation metal tube 1 is sleeved with an inner shell 4, and the outer ring surfaces of both ends of the inner shell 4 are fixedly connected with sealing pieces 3, and the outer ring surface of the sealing piece 3 is fixedly connected with an outer cover shell 2, and auxiliary cavity holes 5 are fixedly opened on the inner shell 4 at equal intervals. The outer cover shell 2, the sealing piece 3 and the inner shell 4 constitute a closed protective cavity. The stable pressure-resistant component 6 includes a lower arc plate 601, which is located in a protective cavity formed by an outer cover shell 2, a sealing plate 3 and an inner sleeve shell 4. A hollow column cavity part 602 is fixedly connected to the middle part of the lower arc plate 601, and a downward column cavity tube 604 is sleeved on the hollow column cavity part 602. An upper arc plate 603 is fixedly connected to the upper end of the downward column cavity tube 604, and a triangular block 605 is symmetrically fixedly connected to the bottom of the inner cavity of the downward column cavity tube 604. A spring 606 is fixedly connected to the inner arc surface of the upper arc plate 603, and an auxiliary disc 607 is fixedly connected to the bottom of the spring 606. A vertical column 608 is plugged and fixedly connected to the middle part of the auxiliary disc 607, and an oblique groove 609 is opened on the vertical column 608, and a Z-shaped part 610 is slidably connected in the oblique groove 609.

[0023] in: Reinforcing ribs are arranged inside the heat dissipation metal tube 1 to improve the strength of the heat dissipation metal tube 1 .

[0024] The auxiliary cavity 5 is mainly used for filling thermal grease. The thermal grease has good filling performance, can adapt to the small gap between the heat dissipation metal tube 1 and the auxiliary device designed by the present invention, and will not dry up during long-term use.

[0025] The stable pressure-resistant component 6 is used to reduce deformation damage to the heat dissipation metal tube 1 caused by the fastening force when the heat dissipation metal tube 1 is installed on a power device or a heat sink using a clamp.

[0026] The lower arc plate 601 can be used to stabilize the hollow column cavity 602 and can be used to absorb the heat absorbed by the heat dissipation metal tube 1 .

[0027] The hollow column cavity 602 is matched with the downward column cavity 604 ; the inclined surface of the triangular block 605 is matched with the inclined surface of the Z-shaped member 610 .

[0028] The spring 606 is used to assist the resetting of the disc 607 ; the oblique groove 609 is adapted to the middle of the Z-shaped member 610 .

[0029] The vertical column 608 can move directly toward the upper arc plate 603 when the outer cover shell 2 or the upper arc plate 603 is pressed, so as to offset the force borne by the upper arc plate 603 .

[0030] For further examples, please refer to Figure 2 , Figures 4 to 7 As shown: The heat dissipation auxiliary component 7 is used for heat dissipation auxiliary and high temperature warning of the heat dissipation metal tube 1. The heat dissipation auxiliary component 7 includes a guide member 701, which is fixedly connected to the surface of the lower arc plate 601. A detection cavity 702 is opened in the guide member 701. An annular airbag 703 is fixedly connected in the detection cavity 702. An annular sliding member 704 is slidably connected in the detection cavity 702. A first electrical contact 705 is fixedly connected to the annular sliding member 704, and a second electrical contact 706 is fixedly connected to the top of the inner wall of the detection cavity 702.

[0031] in: The heat dissipation auxiliary component 7 is used for heat dissipation auxiliary and high temperature warning of the heat dissipation metal tube 1.

[0032] The guide member 701 provides environmental support for the operation of the heat dissipation auxiliary component 7 and also assists the stable movement of the vertical column 608 .

[0033] When the heat dissipating metal tube 1 is subjected to a high temperature, the annular airbag 703 will be indirectly heated and then expand.

[0034] There is an electrical connection between the first electrical contact 705 and the second electrical contact 706. When the first electrical contact 705 and the second electrical contact 706 are in contact, the main controller electrically connected to them will control the external early warning device to issue an early warning, reminding that the temperature of the equipment is too high and the heat dissipation metal tube 1 is insufficient to support the heat dissipation work, and reminding the relevant personnel to perform relevant processing work.

[0035] Everything in the above example works like this: In the initial state: The spring 606 is in a normal state and is not compressed, the annular airbag 703 is not expanded, and the first electrical contact 705 is not in contact with the second electrical contact 706 .

[0036] The following is the working process of the stable pressure-resistant component 6: When in use, the outer cover shell 2 will be mounted on the heat dissipation metal tube 1 together with the inner cover shell 4 through the blocking piece 3, and the outer cover shell 2 will be located in the groove of the external fastener. When the external fastener is fastened to the heat sink by bolts, if the fastening force is too large, the outer cover shell 2 will be deformed to a certain extent. Please refer to the attached Figure 5 At this time, the outer cover shell 2 will force the upper arc plate 603 to move downward with the lower column cavity 604 in the inner cavity of the hollow column cavity 602 on the lower arc plate 601. During this movement, the inclined surface of the triangular block 605 fixedly connected to the bottom of the inner cavity of the lower column cavity 604 will interact with the inclined surface of the Z-shaped member 610 on the vertical column 608. During this process, the movement of the Z-shaped member 610 will promote the vertical column 608 to move away from the guide member 701 through the assistance of the oblique groove 609. At this time, the spring 606 is compressed, and the vertical column 608 will prevent the upper arc plate 603 or the outer cover shell 2 from moving downward during the movement, thereby reducing the possibility of deformation of the heat dissipation metal tube 1. Furthermore, through the design of the downward column cavity 604, the triangular block 605, and the Z-shaped part 610, when the force exerted by the external fastener on the heat dissipation metal tube 1 or the lower arc plate 601 is too large, a reaction force can be given to the fastening force during the process in which the vertical column 608 acts on the lower arc plate 601, thereby indirectly making the heat dissipation metal tube 1 have a certain pressure resistance, effectively improving the service life of the heat dissipation metal tube 1, reducing the frequency of replacement due to damage of the heat dissipation metal tube 1, and reducing maintenance costs; enhancing the heat dissipation effect, making the heat dissipation metal tube 1 run stably and effectively transferring heat; improving system stability, and preventing system instability caused by failure of the heat dissipation metal tube 1; reducing installation difficulty, simplifying the installation process, and reducing human errors; and having wide adaptability.

[0037] Please refer to the above working process Figures 1 to 6 , Figure 8 .

[0038] The following is the working process of the heat dissipation auxiliary component 7: Furthermore, when the temperature of the heat dissipation metal tube 1 is too high, the temperature on it will be conducted to the annular airbag 703 in the detection cavity 702 of the guide member 701 through the inner shell 4 and the lower arc plate 601. At this time, the gas in the annular airbag 703 will expand due to the heat. During the expansion process of the guide member 701, the guide member 701 will move upward in the detection cavity 702 with the annular sliding member 704 and the first electrical contact 705 thereon, and gradually make the first electrical contact 705 approach and finally contact the second electrical contact 706. At this time, the main controller electrically connected to it will control the external alarm device to issue an alarm, reminding that the temperature of the equipment is too high at this time, and the heat dissipation metal tube 1 is insufficient to support the heat dissipation work, and reminding the relevant personnel to carry out relevant processing work; Furthermore, temperature monitoring by changing the shape of the air in the annular airbag 703 due to temperature changes has many advantages. The airbag monitoring has low cost and simple structure, and can provide intuitive and real-time feedback on temperature changes, so that the staff can detect abnormal temperature of the heat dissipation metal tube 1 in time, effectively avoiding the impact of overheating on normal work. This monitoring method also has good adaptability and can work stably under different environments and working conditions; secondly, it improves product quality, ensures the stable operation of the heat dissipation metal tube 1, reduces the risk of equipment failure caused by overheating, and enhances the reliability of the equipment.

[0039] Furthermore, through the design of the lower arc plate 601, during the entire working process, in addition to improving the pressure resistance by virtue of its own shape, effectively protecting the heat dissipation metal tube 1 from damage during the fastening process and extending the service life of the heat dissipation metal tube 1, it can also assist in conducting the temperature of the heat dissipation metal tube 1, so that the annular airbag 703 can more accurately monitor the temperature change, improve the overall performance of the heat dissipation system, and ensure the stable operation of the heat dissipation metal tube 1 in terms of product quality, reduce failures caused by overheating, and improve the reliability and safety of the equipment. In terms of cost, it reduces maintenance costs and equipment losses, and improves production efficiency.

[0040] Please refer to the above working process Figure 2 , Figures 4 to 7 .
