Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a novel SCR regulator. Background Technology

[0002] In the industrial sector, fluid electric heaters are widely used for heating, temperature rise, and viscosity reduction of various fluid media in pipelines across industries such as petroleum, chemical, and power. They replace traditional and outdated heating methods such as steam heating, fuel oil heating, and constant power heating, offering significant advantages such as extremely high energy transfer efficiency, extremely long continuous service life, and no environmental pollution. Each fluid electric heater is typically equipped with a dedicated control cabinet. The power output is controlled by switching the SCR power regulator within the cabinet, thereby achieving controllable design temperatures. For high-power fluid electric heaters, the set current of the selected SCR power regulator is also very large. Under normal operation, its control opening is generally designed to be 70%-80%. For example, a 700kW fluid electric heater, under normal operation, will have a single-phase operating current of approximately 1050A. Furthermore, depending on the properties of the heating medium, the operating current will fluctuate, leading to the problem of the SCR power regulator overheating. When the SCR power regulator overheats and reaches the control board's protection setting, it can trigger an alarm shutdown or even burn out the SCR power regulator, potentially causing partial or complete shutdown of the entire system, resulting in significant economic losses. To address the overheating issue of the SCR power regulator, the distribution cabinet is shipped with a cooling fan installed at the bottom of the heatsink where the SCR power regulator is mounted. When the control board detects that the temperature reaches the fan's activation temperature, it activates the fan to cool the SCR power regulator, and the fan automatically stops when the temperature drops to the fan's shutdown temperature. However, the cooling fan is a consumable component, located at the very bottom of the heatsink. Replacing it requires shutting down the entire system and then manually removing and installing it without visibility, making the operation extremely difficult. Sometimes, maintenance personnel even have to crawl on the ground to perform the replacement. Furthermore, the output copper busbar of the SCR power regulator is already connected to the output cable, directly obstructing the replacement operation and further complicating the process. Furthermore, heat sinks typically use densely packed fins, with adjacent fins very close together. After a period of operation, these gaps accumulate dust, affecting heat dissipation. Operators can only clean them by blowing downwards with an external fan, which is ineffective. Therefore, high-power SCR power regulators have many shortcomings in terms of cooling and heat dissipation, as well as heat sink cleaning, and urgently need improvement. Utility Model Content

[0030] Example:

[0031] like Figure 1 and Figure 2 As shown, a novel SCR adjuster comprises three parts: a support component, an implementation component, and an auxiliary component.

[0032] The supporting component includes a support frame 1, which is an inverted T-shaped frame structure. The vertical portion of the support frame 1 is a flat cuboid structure. Two heat sink mounting slides 11 are evenly arranged on the upper end of the front face of the vertical portion of the support frame 1, and these slides are also inverted T-shaped. Two heat sink mounting slides 12 are evenly arranged on the lower end of the front face of the vertical portion of the support frame 1, and these slides are also inverted T-shaped. At the center of the front face of the vertical portion of the support frame 1, between the heat sink mounting slides 11 and 12, a fan frame 13 is arranged vertically outward. The fan frame 13 is a hollow square frame structure and is integral with the support frame 1. A fan shield 14 is designed at the lower outer edge of the fan frame 13. The fan shield 14 is a narrow cuboid structure and is integral with the fan frame 13. The support frame 1 has circular outer frame fixing grooves C1 evenly arranged on both ends of its vertical portion, and the outer frame fixing grooves C1 have internal threads. The support frame 1 has three sets of 12 SCR power regulator mounting grooves C4 evenly arranged on its back side, and the SCR power regulator mounting grooves C4 have internal threads.

[0033] The implementation components include a left heat sink 2, a right heat sink 3, and a fan 4. For example... Figure 3 As shown, there are two left heat sinks 2. Multiple narrow rectangular left fins 21 are evenly arranged at the front end of each left heat sink 2, and the left fins 21 are integral with the left heat sink 2. Two inverted T-shaped left heat sink slide rails 22 are evenly arranged at the rear end of each left heat sink 2, and the left heat sink slide rails 22 are integral with the left heat sink 2. A protruding flat rectangular intermediate pad 23 is provided on the right end face of each left heat sink 2, and the intermediate pad 23 is integral with the left heat sink 2. Three circular right heat sink insertion slots C2 are evenly arranged on the end face of the intermediate pad 23. A right-angled C-shaped left handle 24 is designed at the center of the left end face of each left heat sink 2, and the left handle 24 is integral with the left heat sink 2. The two sets of left heat sinks 2 are located above and below the left side of the fan frame 13, and are slidably connected to the heat sink mounting upper slide rail 11 and the heat sink mounting lower slide rail 12 via the left heat sink slide rails 22. Figure 4As shown, there are two right heat sinks 3. Multiple narrow rectangular right fins 31 are evenly arranged at the front end of each right heat sink 3, and each right fin 31 is integral with the right heat sink 3. Two inverted T-shaped right heat sink slide rails 32 are evenly arranged at the rear end of each right heat sink 3, and each right heat sink slide rail 32 is integral with the right heat sink 3. Three small cylindrical connector plugs 33 are evenly arranged on the left end face of each right heat sink 3, and each connector plug 33 is integral with the right heat sink 3. A right-angled C-shaped right handle 34 is designed at the center of the right end face of each right heat sink 3, and each right handle 34 is integral with the right heat sink 3. The two sets of right heat sinks 3 are located above and below the right side of the fan frame 13, and are slidably connected to the heat sink mounting upper slide rail 11 and the heat sink mounting lower slide rail 12 via the right heat sink slide rails 32. Figure 5 As shown, the left heat sink 2 and the right heat sink 3 can be joined together by the insertion of three connecting plugs 33 into the three right heat sink insertion slots C2; the middle pad 23 is joined with the left end of the right heat sink 3 to form a complete heat dissipation fin. Figure 7 As shown, there are two fans 4, which are ordinary high-airflow cooling fans; one end of each fan 4 has an external lead wire 41. The external dimensions of the fan 4 match the dimensions of the fan frame 13. The fan 4 is inserted into the fan frame 13, and due to the shielding of the fan shield 14, the fan 4 will not come out of the fan frame 13, and the external lead wire 41 is exposed on the outside.

[0034] The auxiliary components include an outer frame 5, side support plates 51, outer frame fixing bolts 6, side baffles 7, and side baffle fixing bolts 8. There are two side support plates 51, which are perpendicularly connected to the outer frame 5 via two side support plate connecting frames 52. Five circular side baffle fixing grooves C3 are evenly arranged on the left and right end faces of the outer frame 5, and each side baffle fixing groove C3 has an internal thread. Each side support plate 51 has a row of circular outer frame fixing holes K1 and a row of circular side baffle fixing holes K2 near the side support plate connecting frames 52, and each side baffle fixing hole K2 has an internal thread. Figure 8As shown, the internal dimensions of the outer frame 5 match the dimensions of the assembled implementation component and the support component. The outer frame 5 and the side support plate 51 are fitted over the implementation component and the support component. The side support plate 51 is connected to the support frame 1 via an outer frame fixing bolt 6. The outer frame fixing bolt 6 passes through the outer frame fixing hole K1 and is threadedly connected to the outer frame fixing groove C1. The spatial dimensions between the side support plate 51, the side support plate connecting frame 52, and the outer frame 5 match the external dimensions of the left heat sink 2 and the right heat sink 3. By pulling the left handle 24 and the right handle 34 from the left and right sides, the left heat sink 2 and the right heat sink 3 can be pulled horizontally out from the left and right sides of the support frame 1. Similarly, the spatial dimensions between the side support plate connecting frames 52 match the external dimensions of the fan 4. By pulling the fan 4, both fans 4 can be pulled horizontally out from the left and right sides of the support frame 1.

[0035] Two side baffles 7 are provided, and the side baffles 7 are generally of a "right-angled C-shape" structure. External support frames 71 protrude outwards from both ends of the side baffles 7, and the external support frames 71 are integral with the side baffles 7. Five circular side baffle mounting holes K3 are evenly arranged through the front and rear end faces of the external support frames 71. Figure 1 As shown, two side baffles 7 are fastened to the outer frame 5. The side baffle mounting hole K3 is concentric with the side baffle fixing hole K2 and the side baffle fixing groove C3. The side baffle fixing bolt 8 passes through the side baffle mounting hole K3 and is threadedly connected to the side baffle fixing hole K2 and the side baffle fixing groove C3 respectively.

[0036] The following explanations are provided for specific implementation. For example... Figure 10As shown, three SCR power regulators 9 are fixed to the back side of the support frame 1 by bolts and threaded connections to the SCR power regulator mounting slots C4. The input and output copper busbars 100 are bolted to the input and output sides of the SCR power regulators 9. The upper input and output copper busbars 100 connect to the lower port of the control contactor, and the lower input and output copper busbars 100 connect to the output cable of the heater. Signals are sent from the control board of the SCR power regulators 9 to control the actual output of the SCR power regulators 9, thereby adjusting the operation of the heater. In use, the external lead 41 can pass through the space between the side baffle 7 and the left and right heat sinks 2 and 3 and connect to the fan control terminal of the control board of the SCR power regulators 9. If fan 4 is damaged and needs replacement during use, and if the heater can be stopped, after disconnecting the main power supply, simply remove the side panel 7 on the side where the fan 4 is damaged and remove the fan 4 for replacement. If the heater is running and stopping it will cause instability, the operator should take protective measures and disconnect the external lead 41 from the fan control terminal, and then perform the above operation to safely replace the fan while it is powered on. Similarly, if the heater has been running for a long time and the heat sink becomes blocked and needs cleaning, simply remove the side panels 7 on both sides, pull the left handle 24 and the right handle 34 from the left and right sides to pull the left heat sink 2 and the right heat sink 3 horizontally out from the left and right sides of the support frame 1. After cleaning, reinstall them in sequence.

[0037] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
