Description

Technical Field

[0001] This utility model relates to the field of thyristor heat dissipation technology, specifically to an online temperature detection device for thyristor water-cooled radiators. Background Technology

[0002] As is well known, a thyristor is short for silicon controlled rectifier, also known as a silicon controlled rectifier. It is characterized by its small size, relatively simple structure, and powerful function, and is one of the most commonly used semiconductor devices. This device is widely used in various electronic devices and products, and is often used for controlled rectification, inversion, frequency conversion, voltage regulation, contactless switching, etc. As a semiconductor device, a thyristor will generate a large power loss when passing through it, which will cause its temperature to rise. In order to keep the operating temperature of the thyristor within a safe range, a heat sink is needed for heat conduction and dissipation.

[0003] Currently, thyristors are treated with heat sink fins, with copper tubes inserted inside the fins to transport coolant, thus achieving heat conduction and further improving the heat dissipation effect of the thyristor. However, when the coolant flows from one side to the other through the copper tubes, the water already contains heat when it enters the middle of the thyristor, significantly reducing its heat absorption capacity. Therefore, the heat dissipation efficiency in the middle of the thyristor is much lower than that at the edge, resulting in poor heat dissipation in the corresponding middle position. To address this, an online temperature detection device for thyristor water-cooled heat sinks is proposed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an online temperature detection device for silicon controlled rectifier water-cooled radiators, so as to solve the technical problems mentioned in the background above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an online temperature detection device for a silicon controlled rectifier water-cooled radiator, comprising a base plate, a silicon controlled rectifier body mounted on the top of the base plate, a heat dissipation component for heat dissipation on the upper surface of the silicon controlled rectifier body, and a heat dissipation fan capable of blowing air onto the heat dissipation component mounted on the top of the heat dissipation component. The heat dissipation assembly includes multiple sets of heat dissipation fins arranged side by side. The bottom of each set of heat dissipation fins is fixed with a positioning plate that abuts against the upper surface of the thyristor body. Unit copper tubes are mounted on both sides of each set of heat dissipation fins above the positioning plate. The beginning and end of two adjacent sets of unit copper tubes are connected by U-shaped tubes. Each unit copper tube includes a first return tube and a second return tube located on both sides of the heat dissipation fins, and the ends of the first return tube and the second return tube are connected by U-shaped tubes.

[0006] As a preferred technical solution, multiple sets of unit copper pipes are connected in series to form a heat dissipation copper pipe. There are two sets of heat dissipation copper pipes, and the multiple sets of heat dissipation fins are divided into two parts from the middle. One end of the heat dissipation copper pipe is connected to a water inlet pipe, and the other end of the heat dissipation copper pipe is connected to a water outlet pipe.

[0007] As a preferred technical solution, a side strip is fixed at the edge of the top of the positioning plate in the length direction, and the side strip is sleeved on the outer wall of the inlet pipe and the outlet pipe.

[0008] As a preferred technical solution, the bottom of each set of heat dissipation fins extends through to the bottom of the positioning plate and contacts the top of the thyristor body, and the positioning plate is made of heat-insulating material.

[0009] As a preferred technical solution, a temperature acquisition module is installed at the top and near the middle of the base plate, and a temperature acquisition chip connected to the temperature acquisition module is provided on one side of each group of heat dissipation fins.

[0010] As a preferred technical solution, the unit copper tube is fixed with alternating baffles, and multiple sets of baffles and the unit copper tube form a W-shaped channel.

[0011] As a preferred technical solution, the top of the base plate is provided with a positioning groove for placing the thyristor body, and the two sides of the positioning groove are provided with support strips that abut against the bottom of the positioning plate.

[0012] In summary, the present invention has the following main advantages: This invention uses unit copper tubes to allow coolant to flow from the center to the edge of the heat dissipation fin assembly. The coolant absorbs heat from inside the heat dissipation fins, discharges it to the outside for cooling, and then flows back. The turbulence plate extends the time for the coolant to exchange heat with the heat dissipation fins, thereby achieving a better heat dissipation effect. The temperature acquisition plate constantly acquires the temperature data of the heat dissipation fins, and the temperature data of the heat dissipation fins can be seen intuitively through the display terminal, thereby determining whether there is a blockage in the unit copper tube. This can improve the service life of the thyristor body. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] Online temperature monitoring device for silicon controlled rectifier water-cooled heat sinks, such as Figures 1 to 6 As shown, it includes a base plate 100, a thyristor body 120 is mounted on the top of the base plate 100, a heat dissipation component 200 for heat dissipation is provided on the upper surface of the thyristor body 120, and a heat dissipation fan 300 capable of blowing air onto the heat dissipation component 200 is mounted on the top of the heat dissipation component 200. The heat dissipation assembly 200 includes multiple sets of heat dissipation fins 210 arranged side by side. The bottom of the multiple sets of heat dissipation fins 210 is fixed with a positioning plate 110 that abuts against the upper surface of the thyristor body 120. Above the positioning plate 110, on both sides of each set of heat dissipation fins 210, unit copper tubes 220 are installed. The first and last ends of two adjacent sets of unit copper tubes 220 are connected by U-shaped tubes 224. The unit copper tubes 220 include a first return tube 222 and a second return tube 223 located on both sides of the heat dissipation fins 210, and the ends of the first return tube 222 and the second return tube 223 are connected by U-shaped tubes 224. Inside the unit copper tube 220, baffles 225 are fixed in an alternating manner, and multiple sets of baffles 225 and the unit copper tube 220 form a W-shaped channel; A temperature acquisition module 250 is installed on the top and near the middle of the base plate 100. Each set of heat dissipation fins 210 has a temperature acquisition chip 260 on one side that is connected to the temperature acquisition module 250. Multiple sets of unit copper pipes 220 are connected in series to form a heat dissipation copper pipe. There are two sets of heat dissipation copper pipes, and the multiple sets of heat dissipation fins 210 are divided into two parts from the middle. One end of the heat dissipation copper pipe is connected to the water inlet pipe 240, and the other end of the heat dissipation copper pipe is connected to the water outlet pipe 230.

[0018] It is worth noting that, as per the instruction manual... Figure 3 , Figure 4 and Figure 5As shown, the first deflection tube 222 and the second deflection tube 223 are located on both sides of the heat dissipation fin 210 and are staggered, so that heat exchange can be achieved between the upper and lower parts of the heat dissipation fin 210. External coolant enters the unit copper pipe 220 through the inlet pipe 240, flows from the first return pipe 222 to the second return pipe 223, and enters the adjacent unit copper pipe 220 to exchange heat with the heat dissipation fins 210 on one side (the coolant absorbs the heat inside the heat dissipation fins 210). Finally, it is discharged from the outlet pipe 230 and flows back again, thus continuously dissipating heat from the heat dissipation fins 210. The cooling fan 300 blows air onto the heat dissipation fins 210 and the unit copper pipes 220 on both sides, so that the air in the space between the two adjacent sets of heat dissipation fins 210 can circulate. Multiple sets of unit copper pipes 220 are connected in series to form a heat dissipation copper pipe, which flows from the heat dissipation fin group from the center to the two side edges, which can prevent heat accumulation in the middle and poor heat dissipation effect, thereby improving the heat dissipation effect of the heat dissipation fins 210. When the coolant flows within the unit copper tube 220, the baffles 225 act as a barrier, causing the coolant to fill the channel formed by two adjacent sets of baffles 225. This allows the coolant to briefly reside within the channel, providing sufficient time for heat exchange with the heat dissipation fins 210. Meanwhile, the temperature acquisition chip 260 continuously acquires the temperature data of the heat dissipation fins 210 and transmits it to the temperature acquisition module 250. This data is then compared with the preset maximum and minimum temperatures. If the temperature difference is outside the preset range, the temperature acquisition module 250 will send an alarm to the display terminal, reminding personnel to take timely countermeasures to protect the SCR body 120. The operator can visually observe the temperature data of the heat dissipation fins 210 on the display terminal to determine if the unit copper tube 220 is blocked, thus extending the service life of the SCR body 120.

[0019] Please refer to this carefully. Figure 2 and Figure 3 The top of the positioning plate 110 is fixed with a side strip 140 at the edge position in the length direction. The side strip 140 is sleeved on the outer wall of the water inlet pipe 240 and the water outlet pipe 230. Both the water inlet pipe 240 and the water outlet pipe 230 are sleeved with U-shaped buckles 221 that are fixed to the heat dissipation fins 210.

[0020] The inlet pipe 240 and outlet pipe 230 are constrained so that the external coolant can enter and exit the unit copper pipe 220 to achieve heat exchange.

[0021] Please refer to this carefully. Figure 3 Each heat dissipation fin 210 extends from the bottom of the positioning plate 110 and contacts the top of the thyristor body 120. The positioning plate 110 is made of heat-insulating material.

[0022] This allows the bottom of the heat sink fins 210 to directly contact the thyristor body 120, thereby absorbing the heat inside the thyristor body 120 to achieve the final heat dissipation purpose. The heat-insulating positioning plate 110 can prevent heat from entering the temperature acquisition module 250, thus protecting it.

[0023] Please refer to this carefully. Figure 1 and 2 The top of the base plate 100 is provided with a positioning groove 130 for placing the thyristor body 120, and the two sides of the positioning groove 130 are provided with support strips that abut against the bottom of the positioning plate 110.

[0024] The positioning groove 130 constrains the thyristor body 120, preventing the thyristor body 120 from shifting at the bottom of the base plate 100.

[0025] In use, external coolant enters the unit copper pipe 220 through the inlet pipe 240, flows from the first return pipe 222 to the second return pipe 223, and enters the adjacent unit copper pipe 220 to exchange heat with the heat dissipation fins 210 on one side (the coolant absorbs the heat inside the heat dissipation fins 210). Finally, it is discharged from the outlet pipe 230 and flows back again, thus continuously dissipating heat from the heat dissipation fins 210. The cooling fan 300 blows air onto the heat dissipation fins 210 and the unit copper pipes 220 on both sides, so that the air in the space between the two adjacent sets of heat dissipation fins 210 can flow. Multiple sets of unit copper pipes 220 are connected in series to form a heat dissipation copper pipe, which flows from the heat dissipation fin group from the center to the two side edges, which can prevent heat accumulation in the middle and poor heat dissipation effect, thereby improving the heat dissipation effect of the heat dissipation fins 210. When the coolant flows within the unit copper tube 220, the baffles 225 act as a barrier, causing the coolant to fill the channel formed by two adjacent sets of baffles 225. This allows the coolant to briefly reside within the channel, providing sufficient time for heat exchange with the heat dissipation fins 210. Meanwhile, the temperature acquisition chip 260 continuously acquires the temperature data of the heat dissipation fins 210 and transmits it to the temperature acquisition module 250. This data is then compared with the preset maximum and minimum temperatures. If the temperature difference is outside the preset range, the temperature acquisition module 250 will send an alarm to the display terminal, reminding personnel to take timely countermeasures to protect the SCR body 120. The operator can visually observe the temperature data of the heat dissipation fins 210 on the display terminal to determine if the unit copper tube 220 is blocked, thus extending the service life of the SCR body 120.
