Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of electrical equipment, and in particular to a heat dissipation device for electrical equipment and electrical equipment of a hydropower plant. Background Art

[0002] During the operation of electrical equipment, the internal electronic components generate a large amount of heat. If this heat cannot be dissipated promptly and effectively, the internal temperature of the equipment will rise, which will in turn affect the performance and life of the electronic components. In related technologies, the heat dissipation devices of most electrical equipment adopt a fixed installation method. This installation method is often based on a preset heat dissipation condition during design and lacks flexibility and adaptability. However, during actual operation, the heat dissipation requirements of electrical equipment may change due to various factors such as the working environment and load changes, resulting in a mismatch between the existing heat dissipation devices and the actual heat dissipation requirements, which seriously affects the performance of the electrical equipment. Summary of the Invention

[0003] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0004] During the stable and continuous operation of electrical equipment, the heat generated by electronic components inside the equipment continuously causes the temperature inside the equipment to gradually rise. The performance of electronic components will also change significantly with the temperature change.

[0005] However, in related technologies, heat sinks are often fixed to electrical equipment and difficult to adjust in real time based on actual cooling requirements. This often leads to a mismatch between the heat sink and the actual cooling requirements during operation. In particular, when cooling requirements increase, the heat sink may not be able to dissipate heat promptly and effectively, causing the internal temperature of the equipment to continue to rise. This in turn affects the normal operation of electronic components and leads to performance degradation, such as reduced output power and decreased control accuracy.

[0006] To this end, the present invention proposes a heat dissipation device for electrical equipment and electrical equipment in a hydropower plant, which can improve the heat dissipation efficiency of the electrical equipment by connecting the heat dissipation port with the heat exchange port.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 6As shown, an embodiment of the present invention provides a heat dissipation device for electrical equipment. The electrical equipment has a heat dissipation port. The heat dissipation device for electrical equipment includes a mounting frame 10, a liquid cooling assembly 20 and an air guide assembly 30. The mounting frame 10 includes a heat exchange box 11, a first clamping plate 131 and a second clamping plate 132 arranged opposite to each other. The heat exchange box 11 has a heat exchange port 111. The first clamping plate 131 and the second clamping plate 132 are slidable relative to the heat exchange box 11. The first clamping plate 131 and the second clamping plate 132 are used to clamp the electrical equipment so that the heat dissipation port is docked with the heat exchange port 111. The liquid cooling assembly 20 includes a liquid storage tank 21, a circulation pipe 23 and a circulation pump 25. The liquid storage tank 21 is used to store coolant. Both ends of the circulation pipe 23 are connected to the liquid storage tank 21. The circulation pump 25 is provided in the circulation pipe 23. The circulation pump 25 is used to accelerate the flow of coolant in the circulation pipe 23. The circulation pipe 23 is arranged in an S shape in the heat exchange box 11.

[0034] The air guide assembly 30 includes at least one fan 31. The side wall of the heat exchange box 11 is provided with at least one air hole 112. The air hole 112 and the heat exchange port 111 are located on both sides of the circulation pipe 23. The fan 31 and the air hole 112 are arranged in a one-to-one correspondence. The fan 31 is used to cause the air in the heat exchange box 11 to be discharged to the outside through the air hole 112 or the outside air to enter the electrical equipment through the air hole 112 and the heat exchange port 111.

[0035] Specifically, the electrical equipment itself is designed with a heat dissipation vent as a channel for heat dissipation. The mounting bracket 10 can be clamped to the electrical equipment via the first clamping plate 131 and the second clamping plate 132 to secure the heat dissipation device. This allows the heat dissipation vent to connect with the heat exchange port 111, allowing the heat dissipation device to be installed on the electrical equipment as needed, significantly improving the heat dissipation efficiency of the electrical equipment and ensuring stable and reliable performance of the equipment during long-term operation.

[0036] The liquid cooling component 20 absorbs and carries away the heat generated by the electrical equipment through the circulating coolant. The liquid storage tank 21 serves as a storage container for the coolant, which can ensure that the coolant will not dry up during long-term operation. The circulating pump 25 is the power source for the circulation of the coolant. It is installed on the circulating pipe 23 and accelerates the flow rate of the coolant in the circulating pipe 23 by continuous operation, thereby enhancing the cooling effect. The circulating pipe 23 is arranged in an S shape in the heat exchange box 11. This design not only increases the contact area between the coolant and the inner wall of the heat exchange box 11, but also extends the residence time of the coolant in the heat exchange box 11, making the heat exchange more sufficient and efficient. In this embodiment, the coolant can be set to water or other heat exchange medium.

[0037] The air guide assembly 30 utilizes the wind generated by the fan 31 to assist in heat dissipation. The sidewalls of the heat exchange box 11 are provided with at least one air hole 112. These air holes 112 and the heat exchange port 111 are located on either side of the circulation tube 23, forming a channel for air circulation. The fans 31 are arranged in a one-to-one correspondence with the air holes 112. They can flexibly adjust their operating state based on heat dissipation requirements, either directing the hot air within the heat exchange box 11 to the outside through the air holes 112 or introducing fresh air from the outside into the electrical equipment through the air holes 112 and the heat exchange port 111, achieving air circulation and further reducing the equipment temperature.

[0038] In summary, the heat dissipation device for electrical equipment provided by the present invention can be quickly fixed through the first clamping plate 131 and the second clamping plate 132, ensuring rapid docking between the heat dissipation port and the heat exchange port 111, thereby establishing an efficient heat transfer channel, forming a set of efficient, intelligent and comprehensive heat dissipation system, which can not only significantly improve the heat dissipation efficiency of electrical equipment, ensure that the equipment maintains stable and reliable performance during long-term operation, but also has many advantages such as simple installation and convenient maintenance.

[0039] In this embodiment, the heat exchange box 11 further includes a first box frame 12 and a second box frame 14. The first clamping plate and the second clamping plate are slidably mounted on the first box frame 12, and the liquid cooling assembly is mounted on the second box frame 14. Of course, in some embodiments, the first box frame 12 and the second box frame 14 may also be integrated.

[0040] In some embodiments, the heat dissipation device for electrical equipment also includes an adjustable support 40, which is arranged at the bottom of the heat exchange box 11. The adjustable support 40 includes a support plate 41 and multiple hydraulic support rods 43. The multiple hydraulic support rods 43 are spaced apart and arranged on the side of the support plate 41 away from the heat exchange box 11.

[0041] That is, during installation, the first and second clamping plates 131, 132 initially clamp the electrical device by sliding the sliding portion 134 within the sliding groove 153. The adjustable support 40 further fine-tunes the height and angle of the heat sink by adjusting the length of the hydraulic strut 43, ensuring precise alignment between the heat dissipation port and the heat exchange port 111. This coordinated design not only improves installation efficiency but also significantly enhances the stability and sealing of the connection between the heat sink and the electrical device.

[0042] Optionally, an adjustable support 40 is provided on a side of the heat exchange box 11 away from the first clamping plate 131, so that the height and angle of the heat dissipation device can be adjusted to a greater extent during installation to ensure accurate docking of the heat dissipation port with the heat exchange port 111. At least some of the hydraulic support rods 43 are provided at the four corners of the support plate 41.

[0043] In this embodiment, if Figure 3As shown, the liquid cooling assembly 20 also includes a water pump 22, which is located at the water inlet of the circulation pump 25, so that it can cooperate with the circulation pump 25 to ensure the circulation speed of the coolant and help improve the cooling efficiency. In addition, both the fan 31 and the air hole 112 can be provided with two.

[0044] like Figure 1 、 Figure 4 As shown, in some embodiments, the heat exchange box 11 includes a bidirectional screw 133, a first side plate 151 and a second side plate 152 arranged opposite to each other, the first side plate 151 and the second side plate 152 are both provided with a slide groove 153, the straight line in which the extension direction of the slide groove 153 is located is parallel to the straight line in which the axial direction of the bidirectional screw 133 is located, the first clamping plate 131 and the second clamping plate 132 both have a sliding portion 134, and the sliding portion 134 is slidably arranged in the slide groove 153; the bidirectional screw 133 has a first thread segment 1331 and a second thread segment 1332 with opposite rotation directions, one of the first clamping plate 131 and the second clamping plate 132 is slidably arranged in the first thread segment 1331, and the other of the first clamping plate 131 and the second clamping plate 132 is arranged in the second thread segment 1332.

[0045] Specifically, the first and second side plates 151, 152 serve as the supporting structures on both sides of the heat exchange box 11. The straight lines extending from the chute 153 of each of the first and second side plates 151, 152 are parallel to the straight line axially extending from the bidirectional screw 133, thereby ensuring stable and reliable sliding. The first and second clamping plates 131, 132 each have a sliding portion 134. The sliding portion 134 mates with the chute 153, allowing the first and second clamping plates 131, 132 to move freely and stably within the chute 153, ensuring accurate clamping while reducing wear and energy loss due to friction.

[0046] That is, the bidirectional screw 133 has a first threaded segment 1331 and a second threaded segment 1332 that rotate in opposite directions. One of the first clamping plate 131 and the second clamping plate 132 is slidably mounted on the first threaded segment 1331, while the other is mounted on the second threaded segment 1332. Optionally, the first clamping plate 131 is threadedly connected to the first threaded segment 1331, and the second clamping plate 132 is threadedly connected to the second threaded segment 1332.

[0047] When the bidirectional screw 133 rotates, the bidirectional screw 133 can drive the first clamping plate 131 to move along the slide groove 153 through the first thread segment 1331, and the second thread segment 1332 can drive the second clamping plate 132 to move, thereby realizing synchronous and reverse movement between the first clamping plate 131 and the second clamping plate 132, which helps to achieve rapid clamping, ensures that the heat dissipation device can be tightly and stably installed on the electrical equipment, and also provides strong guarantee for its subsequent heat dissipation work.

[0048] Furthermore, the mounting frame 10 also includes a driver 135, and two bidirectional screws 133 are provided. The two bidirectional screws 133 are respectively arranged in the slide grooves 153 of the first side plate 151 and the second side plate 152. The output end of the driver 135 is connected to one of the two bidirectional screws 133. A transmission assembly 136 is provided between the two bidirectional screws 133 to enable the two bidirectional screws 133 to rotate synchronously, thereby ensuring stability during the clamping process.

[0049] Furthermore, the transmission assembly 136 includes a first pulley 1361, a second pulley 1362 and a synchronous belt 1363. The first pulley 1361 is provided on one of the two bidirectional screws 133, and the second pulley 1362 is provided on the other of the two bidirectional screws 133. The synchronous belt 1363 is sleeved on the first pulley 1361 and the second pulley 1362, which not only ensures that the rotation of the two bidirectional screws 133 is completely synchronized, but also greatly improves the stability and reliability of the transmission.

[0050] Optionally, the driver 135 may be configured as an electric motor, a pneumatic motor, or the like.

[0051] like Figure 1 and Figure 3 As shown, in some embodiments, the mounting bracket 10 further includes a barrier net 17, which is disposed in the heat exchange box 11, and the barrier net 17 is located between the heat exchange port 111 and the circulation pipe 23. First, from the perspective of airflow organization, the barrier net 17 can effectively guide the airflow entering from the heat exchange port 111, making it more evenly distributed around the circulation pipe 23, thereby improving the efficiency of heat exchange. Secondly, during the operation of electrical equipment, some tiny impurities or foreign matter may be generated. If these impurities or foreign matter directly enter the heat exchange box 11, they may cause blockage or wear, thereby affecting the heat dissipation effect. The barrier net 17 can block these impurities or foreign matter from the outside, protecting the circulation pipe 23 from harm.

[0052] Furthermore, the barrier net 17 may be made of a high-strength, corrosion-resistant alloy material, which not only ensures the durability of the barrier net 17 but also enables it to maintain stable performance in the face of complex working environments.

[0053] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, in some embodiments, the air guide assembly 30 also includes a bellows 33, and the fan 31 is rotatably arranged in the bellows 33. The bellows 33 includes a first side wall 331 and a second side wall 332 that are opposite to each other. The first side wall 331 is provided with a through groove 3311, and the second side wall 332 is provided with a positioning groove 3321 that matches the through groove 3311. The air guide assembly 30 also includes a dustproof net 35, one end of the dustproof net 35 is inserted into the positioning groove 3321 through the through groove 3311, and the dustproof net 35 is located on the side of the fan 31 away from the heat exchange box 11.

[0054] Specifically, the dust screen 35 is located on the side of the fan 31 away from the heat exchange box 11, effectively intercepting and blocking external dust and impurities to the greatest extent possible. One end of the dust screen 35 is inserted into the positioning slot 3321 through the through slot 3311, making it not only secure and reliable but also easy to remove and clean. When a certain amount of dust and impurities accumulate on the dust screen 35, the operator can easily remove it from the air box 33 for cleaning or replacement, thus ensuring the long-term stable operation of the fan 31.

[0055] Furthermore, the first sidewall 331 is provided with a retaining strip 3312. The air guide assembly 30 also includes a slide bar 37 having a first plate 371 and a second plate 372 connected thereto. The first plate 371 is provided with a retaining slot 3711 that mates with the slide bar 37. The second plate 372 covers the through-slot 3311 to block the through-slot 3311, preventing dust and impurities from entering the interior of the air box 33 through the through-slot 3311. During actual installation, the operator simply slides the slide bar 37 along the retaining strip 3312 and then inserts the dust screen 35 through the through-slot 3311 into the positioning slot 3321, thereby ensuring that the dust screen 35 is installed conveniently and securely. In this embodiment, the slide bar 37 is L-shaped.

[0056] In some embodiments, the bellows 33 also includes a third side wall 333 and a fourth side wall 334. The third side wall 333 and the fourth side wall 334 are arranged opposite to each other and are respectively located at the two ends of the first side wall 331. A support rod 335 is provided between the third side wall 333 and the fourth side wall 334, and the fan 31 is provided on the support rod 335.

[0057] Optionally, two fans 31 may be provided.

[0058] like Figure 1 and Figure 3 As shown, in some embodiments, the circulation pipe 23 includes multiple straight pipes 231, multiple U-shaped pipes 232 and multiple fins, the two ends of the U-shaped pipe 232 are correspondingly connected to two adjacent straight pipes 231, and the multiple fins are spaced apart on the straight pipe 231 along the length direction of the straight pipe 231.

[0059] In practice, as the coolant flows through circulation pipe 23, it sequentially passes through multiple straight tubes 231 and U-shaped tubes 232. In straight tubes 231, the coolant rapidly absorbs heat from the electrical equipment through the highly thermally conductive walls of straight tubes 231. In U-shaped tubes 232, the coolant's tortuous path and thorough mixing achieve uniform temperature distribution. The fins further diffuse the coolant's cooling capacity and exchange heat with the air within the heat exchanger. This synergistic effect enables circulation pipe 23 to achieve efficient heat exchange, rapidly removing heat from the electrical equipment and dissipating it to the outside environment.

[0060] Furthermore, the circulation pipe 23 can be fixed to the heat exchange box 11 through the U-shaped pipe 232 at the bottom, and the straight pipe 231 extends along the height direction of the heat exchange box 11, and the length of the circulation pipe 23 in the extension direction of the straight pipe 231 is slightly smaller than the height of the heat exchange box 11, so that the circulation pipe 23 can make full use of the vertical space in the heat exchange box 11, increase the contact area between the coolant and the wall of the heat exchange box 11, and thus improve the heat exchange efficiency.

[0061] In addition, an embodiment of the present invention also provides electrical equipment for a hydropower plant, which includes an electrical box and a heat dissipation device for the electrical equipment provided in the above embodiment. The electrical box has a heat dissipation port, and the first clamping plate 131 and the second clamping plate 132 of the mounting frame 10 clamp the electrical box so that the heat exchange port 111 of the heat exchange box 11 is docked with the heat dissipation port.
