Description

Technical Field

[0001] The power electronic component manufacturing apparatus of this application relates more specifically to the field of electrical circuit temperature control devices, and more specifically to an electrical circuit temperature control device for fire prevention in a tobacco logistics park. Background Technology

[0002] In the electrical systems of tobacco logistics parks, ordinary metal or PVC conduits are often used when cables are threaded through them. The inner wall of the conduit is not equipped with an insulating buffer layer and is in direct contact with the cable sheath. This results in no heat dissipation gap between the cable and the conduit, leading to low heat dissipation efficiency of the cable. Consequently, the cable is prone to insulation failure under high-temperature conditions, thereby increasing the risk of fire caused by short circuits in the electrical circuits.

[0003] In the temperature control of electrical circuits in tobacco logistics parks, natural heat dissipation or simple fan cooling is usually used. This method cannot dynamically adjust the temperature according to the real-time temperature of the electrical circuits, resulting in low cooling efficiency. When the temperature of the circuit rises suddenly due to high load operation, high ambient temperature, or heat accumulation in the components, this method is difficult to cool down quickly, causing the circuit to be in a high-temperature state for a long time, accelerating the aging and damage of the insulation layer, and significantly increasing the risk of short circuits and fires. Utility Model Content

[0004] To address the problem of electrical circuits being unable to be dynamically controlled in real time, resulting in high temperatures and increased fire risk, this application provides an electrical circuit temperature control device for fire prevention in tobacco logistics parks.

[0005] The electrical circuit temperature control device for fire prevention in tobacco logistics parks provided in this application adopts the following technical solution:

[0006] A temperature control device for electrical circuits used in fire prevention and control in tobacco logistics parks includes a first box and a second box. The first box has a temperature control chamber 1 inside, and the second box has a temperature control chamber 2 inside that communicates with the first temperature control chamber. A drive component for driving the flow of coolant inside the second temperature control chamber is provided on one side of the surface of the second box, and a temperature control mechanism for controlling the temperature of electrical circuits is provided on one side of the surface of the second box.

[0007] The drive assembly includes an inlet pipe and an outlet pipe inserted on one side of the second surface of the housing, and both the inlet pipe and the outlet pipe are connected to the second temperature control chamber.

[0008] The temperature control mechanism includes a temperature control box fixed on one side of the surface of the second box and temperature control tubes inserted on both sides of the surface of the second box. A fan for generating airflow is fixed inside the temperature control box. Part of the surface of the temperature control tube is located inside the second temperature control chamber. The first box and the second box are fixedly connected by a positioning component.

[0009] By adopting the above technical solution, the drive component circulates the coolant inside temperature control chamber 1 and temperature control chamber 2, while the coolant cools the airflow in the temperature control pipe, thereby cooling the electrical circuit. The positioning component enables the detachable installation of housing 1 and housing 2, facilitating the replacement of the coolant inside temperature control chamber 1 and temperature control chamber 2.

[0010] Preferably, the surface of the temperature control tube is symmetrically fixed with a sealing ring 1 that is snapped into the inside of the side of the box body 2 near the surface of the temperature control box, and the sealing ring 1 is used to seal the temperature control tube.

[0011] By adopting the above technical solution, during the process of inserting the temperature control tube into the surface of the second box near the temperature control box, the connection between the second box and the temperature control tube is sealed by the deformation of the sealing ring, and the temperature control tube is fixed to one side of the surface of the second box to prevent coolant from entering the interior of the second box or leaking out.

[0012] Preferably, the positioning assembly includes a positioning block symmetrically fixed on one side of a first surface of the housing and a positioning seat symmetrically fixed on one side of a second surface of the housing. The positioning block is inserted inside the positioning seat. A driving block is abutted on the side of the positioning seat away from the second surface of the housing. A positioning post for positioning the positioning block inside the positioning seat is fixed on the side of the driving block near the positioning seat. The end of the positioning post away from the driving block is threaded to one side of the surface of the positioning block and one side of the surface of the positioning seat.

[0013] By adopting the above technical solution, the positioning block is inserted on one side of the surface of the positioning seat. When the first box and the second box come into contact, the positioning block comes into contact with the positioning seat. The rotating drive block provides power to the positioning column, causing the positioning column to move downward and fix the positioning block and the positioning seat together, thereby completing the fixation of the first box and the second box.

[0014] Preferably, a frame is fixedly provided on one side of the surface of the first box near the second box, and a sealing strip is fixedly provided on the surface of the frame.

[0015] By adopting the above technical solution, during the splicing process of housing 1 and housing 2, the insert frame is inserted on the side of housing 2 near housing 1, and the sealing strip is inserted on the side of housing 2 near housing 1 along with the insert frame, thereby sealing the splicing point of housing 1 and housing 2 and preventing coolant from entering the interior of housing 1 and housing 2 and from leaking out.

[0016] Preferably, the drive assembly further includes a protective cover fixed on the side of the housing second near the surface of the inlet pipe, and a centrifugal pump fixed on the side of the housing second near the surface of the protective cover is abutted inside the protective cover. The inlet of the centrifugal pump is connected to the inlet pipe, and the outlet of the centrifugal pump is connected to the outlet pipe.

[0017] By adopting the above technical solution, the centrifugal pump provides power to the inlet pipe, which in turn guides the coolant in the temperature control chamber two into the inside of the inlet pipe. Subsequently, the coolant is guided from the inside of the inlet pipe into the inside of the outlet pipe, and then the coolant is guided back into the temperature control chamber two through the outlet pipe, so that the coolant inside the temperature control chamber two is in a flowing state, thereby better controlling the temperature of the electrical circuits inside the chamber one and the chamber two.

[0018] Preferably, a temperature sensor for monitoring the temperature of electrical circuits is fixed inside the second housing, and the temperature sensor is electrically connected to the fan.

[0019] By adopting the above technical solution, the temperature of the electrical circuit is monitored by a temperature sensor. When the temperature is too high, the temperature sensor controls the fan to start, so that the fan generates airflow. The airflow flows inside the temperature control tube to the interior of the second and first chambers. During the flow, the airflow is cooled by the coolant, so that the low-temperature airflow cools the electrical circuit, thereby controlling the temperature of the electrical circuit.

[0020] Preferably, both temperature control chamber one and temperature control chamber two are fixedly provided with partition frames, and after the box body one and box body two are spliced ​​together, the partition frames in temperature control chamber one and the partition frames in temperature control chamber two are in an abutting state.

[0021] By adopting the above technical solution, the connecting space between temperature control chamber one and temperature control chamber two is restricted by the partition frame, so that the coolant can only flow from the space where the partition frame does not block the interior of temperature control chamber one and temperature control chamber two, thereby controlling the flow path of the coolant.

[0022] Preferably, the interior of the housing is provided with conduits for installing electrical wiring.

[0023] By adopting the above technical solution, the wires are installed inside the enclosure through pipes, thereby enabling centralized temperature control of the electrical circuits.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The coolant is circulated in temperature control chamber 1 and temperature control chamber 2 by the drive component. At the same time, the fan in the temperature control mechanism generates airflow. The airflow is cooled by the coolant when it passes through the temperature control tube, forming a low-temperature airflow to dissipate heat from the electrical circuit. Meanwhile, the temperature sensor monitors the circuit temperature in real time. When the temperature is too high, the fan is automatically activated to accurately control the temperature of the electrical circuit, thereby achieving efficient and comprehensive cooling of the electrical circuit and greatly improving the safety and reliability of temperature control of electrical circuits in the tobacco logistics park.

[0026] 2. The first and second housings are detachably connected via a positioning assembly. Installation and disassembly can be completed by rotating the drive block, facilitating the replacement of the coolant inside the temperature control chamber. Simultaneously, the connection between the temperature control pipe and the second housing is sealed with a nitrile rubber sealing ring. The insert frame and sealing strip further enhance the sealing performance at the joint between the first and second housings, ensuring the device's sealing performance while simplifying maintenance procedures and improving the device's practicality and convenience during long-term use.

[0049] The following is in conjunction with the appendix Figures 1-12 This application will be described in further detail.

[0050] The electrical circuit temperature control device of this application belongs to the category of power electronic component manufacturing equipment, and provides an electrical circuit temperature control device for fire prevention in tobacco logistics parks.

[0051] Reference Figures 1-12 A temperature control device for electrical circuits used in fire prevention in a tobacco logistics park includes a first box 1 and a second box 2. The first box 1 has a temperature control cavity 13 inside, and the second box 2 has a temperature control cavity 23 inside, which communicates with the first temperature control cavity 13. Both the first temperature control cavity 13 and the second temperature control cavity 23 are fixedly equipped with a partition frame 6. The partition frame 6 is inverted L-shaped, so that the lower end of the first temperature control cavity 13 communicates with the lower end of the second temperature control cavity 23. The middle and upper ends of the first temperature control cavity 13 and the middle and upper ends of the second temperature control cavity 23 are blocked by the partition frame 6. After the first box 1 and the second box 2 come into contact, the partition frame 6 in the first temperature control cavity 13 and the partition frame 6 in the second temperature control cavity 23 are in contact.

[0052] The partition 6 restricts the communication space between temperature control cavity 13 and temperature control cavity 23, so that the coolant can only flow from the space where the partition 6 does not block the interior of temperature control cavity 13 and temperature control cavity 23, thereby controlling the flow path of the coolant and making the coolant flow in a U-shape.

[0053] Reference Figures 1-11 A sealing plug 21 is threaded onto one side of the surface of housing 2. The connection between the sealing plug 21 and housing 2 is connected to the temperature control chamber 23. A drive assembly 3 for driving the flow of coolant inside the temperature control chamber 23 is provided on one side of the surface of housing 2. The drive assembly 3 includes a protective cover 31 fixed to one side of the surface of housing 2. A centrifugal pump 32 is abutted inside the protective cover 31. The flow rate of the centrifugal pump 32 is 3L / min-10L / min to ensure the circulation of coolant. The centrifugal pump 32 is located away from the protective cover 31. The end is fixed on the surface of the second housing 2 near the protective cover 31. The inlet of the centrifugal pump 32 is fixed with an inlet pipe 33, and the inlet of the centrifugal pump 32 is connected to the inlet pipe 33. The outlet of the centrifugal pump 32 is fixed with an outlet pipe 34, and the outlet of the centrifugal pump 32 is connected to the outlet pipe 34. Both the inlet pipe 33 and the outlet pipe 34 pass through the surface of the second housing 2 near the protective cover 31. Both the inlet pipe 33 and the outlet pipe 34 are connected to the temperature control chamber 23. The inlet pipe 33 and the outlet pipe 34 are respectively set on both sides of the surface of the partition frame 6.

[0054] It should be noted that the centrifugal pump 32 consists of a pump body, impeller, motor, pump shaft, and other components. The motor drives the pump shaft to rotate, which in turn drives the impeller fixed on the shaft to rotate at high speed (usually 2900 r / min). When the impeller rotates, the coolant between its blades is thrown towards the edge of the impeller under the action of centrifugal force, so that the coolant gains kinetic and pressure energy. After some of the kinetic energy is converted into pressure energy through the flow channel (volute shape) in the pump casing, it is transported out along the outlet pipe 34. At the same time, a low-pressure area is formed at the center of the impeller due to the coolant being thrown out. Under the action of the pressure difference between the external atmospheric pressure and the impeller center, the coolant is continuously drawn into the impeller through the inlet pipe 33, thereby realizing the continuous delivery of coolant.

[0055] Centrifugal pump 32 provides power to inlet pipe 33 and outlet pipe 34, so that inlet pipe 33 introduces coolant from temperature control chamber 23 into the interior of inlet pipe 33. Then, coolant is introduced from inside inlet pipe 33 into outlet pipe 34 and then guided back into temperature control chamber 23 through outlet pipe 34, so that coolant inside temperature control chamber 23 is in a flowing state, thereby better controlling the temperature of electrical circuits inside housing 1 and housing 2.

[0056] Reference Figures 1-12A temperature control mechanism 5 for controlling the temperature of electrical circuits is provided on one side of the surface of the second enclosure 2. The temperature control mechanism 5 includes a temperature control box 51 fixed on one side of the surface of the second enclosure 2. A fan 52 for generating airflow is fixed inside the temperature control box 51. Multiple temperature control tubes 53 arranged in a rectangular pattern are inserted on both sides of the surfaces of the first enclosure 1 and the second enclosure 2. The number of tube grooves 25 equal to the number of temperature control tubes 53 is opened on both sides of the surfaces of the first enclosure 1 and the second enclosure 2. The surface of the temperature control tube 53 abuts against the inner wall of the tube groove 25. The number of insertion slots equal to the number of temperature control tubes 53 is opened on both sides of the surfaces of the first enclosure 1 and the second enclosure 2. Part of the surface of 53 is located inside the temperature control chamber 13 and the temperature control chamber 23, so that the coolant cools the airflow inside the temperature control tube 53 during the flow process. The surface of the temperature control tube 53 abuts against the inner wall of the insertion groove. The surface of the temperature control tube 53 is symmetrically fixed with sealing rings 531 for sealing between the temperature control tube 53 and the temperature control chamber 23, preventing the coolant from leaking into the temperature control box 51 or the box 2 and box 1. The inner wall of the tube groove 25 is provided with annular grooves 251 that are adapted to and equal in number to the sealing rings 531. The surface of the sealing rings 531 abuts against the inner wall of the annular grooves 251.

[0057] The interior of housing 2 is equipped with a temperature sensor 22 for monitoring the temperature of electrical circuits.

[0058] It should be noted that the user needs to install a controller inside the temperature control box 51 and connect the controller to the fan 52 and the temperature sensor 22 respectively. When the temperature sensor 22 detects that the temperature of the electrical circuit exceeds the threshold, the temperature sensor 22 controls the fan 52 to start. When the temperature sensor 22 detects that the temperature of the electrical circuit drops below the threshold, the temperature sensor 22 controls the fan 52 to turn off.

[0059] Temperature sensor 22 monitors the temperature of the electrical circuit. When the temperature is too high, temperature sensor 22 controls fan 52 to start, causing fan 52 to generate airflow. The airflow flows into the temperature control tube 53 near the temperature control box 51. During the flow of the airflow in the temperature control tube 53, it is cooled by the coolant. The cooled airflow flows into the box 1, controlling the temperature of the electrical circuit in the box 1. The airflow is discharged from the box 1 and the box 2 through the temperature control tube 53 away from the temperature control box 51, preventing hot air from entering the box 1 and the box 2.

[0060] Reference Figures 1-12A positioning assembly 4 is provided between housing 1 and housing 2 to fix housing 1 and housing 2 together. The positioning assembly 4 includes a positioning block 41 symmetrically fixed on one side of the surface of housing 1 and a positioning seat 42 symmetrically fixed on one side of the surface of housing 2. The positioning seat 42 has a positioning groove 421 on the side of the surface near the positioning block 41. The surface of the positioning block 41 abuts against the inner wall of the positioning groove 421, so that the positioning block 41 can be inserted into the inside of the positioning groove 421. The side of the positioning seat 42 away from housing 2 abuts against a driving block 43. The side of the driving block 43 near the surface of the positioning seat 42 is fixed with a positioning post 431 for positioning the positioning block 41 in the positioning groove 421. The side of the positioning block 41 away from housing 1 has a driving groove 411. The inner wall of the driving groove 411 is provided with an internal thread. The surface of the positioning post 431 is provided with an external thread that meshes with the internal thread. The positioning post 431 is threadedly connected to the side of the positioning seat 42 away from housing 2.

[0061] Manually rotating the drive block 43 counterclockwise provides power to the positioning pin 431, causing the drive block 43 to rotate the positioning pin 431 counterclockwise, thus moving the positioning pin 431 upwards along the thread. When the end of the positioning pin 431 away from the drive block 43 is moved to the same horizontal line as the top wall of the positioning groove 421, or when the positioning pin 431 is moved to the inside of the side of the positioning seat 42 away from the surface of the housing 2, the positioning block 41 on the housing 1 is aligned with the positioning groove 421, and the housing 1 is pushed in the direction closer to the housing 2, so that the housing 1 is close to the housing 2. The positioning block 41 approaches the positioning seat 42, thereby inserting the positioning block 41 into the positioning groove 421. When the first box 1 and the second box 2 come into contact, the surface of the positioning block 41 near the positioning seat 42 abuts against the side wall of the positioning groove 421. The driving block 43 is rotated clockwise, causing the driving block 43 to drive the positioning column 431 to rotate clockwise, causing the positioning column 431 to move downward, so that the end of the positioning column 431 away from the driving block 43 is inserted into the driving groove 411, thereby fixing the positioning block 41 and the positioning seat 42 together, thus completing the fixing of the first box 1 and the second box 2.

[0062] Reference Figures 1-12 A frame 11 is fixed on the side of the housing 1 near the housing 2. The side of the frame 11 away from the housing 1 is shaped like a large "U". A slot 24 adapted to the frame 11 is opened on the side of the housing 2 away from the temperature sensor 22. The surface of the frame 11 abuts against the inner wall of the slot 24. A sealing strip 12 is fixed on the surface of the frame 11. The side of the sealing strip 12 away from the housing 1 is shaped like a large "U". A sealing groove 241 adapted to the sealing strip 12 is opened on the inner wall of the slot 24. The surface of the sealing strip 12 abuts against the inner wall of the sealing groove 241.

[0063] A sealing frame 14 is fixed on the side of the housing 1 near the insertion frame 11. A frame-shaped groove 26 adapted to the sealing frame 14 is opened on the side of the housing 2 near the insertion frame 11. The surface of the sealing frame 14 abuts against the inner wall of the frame-shaped groove 26, so that the sealing frame 14 seals the interior of the housing 1 and the housing 2, preventing coolant from entering the interior of the housing 1 and the housing 2 from the connection between the housing 1 and the housing 2.

[0064] As the housing 1 approaches the housing 2, the insert frame 11 gradually inserts into the slot 24. During this process, the insert frame 11 moves the sealing strip 12 closer to the housing 2, causing the side of the sealing strip 12 away from the housing 1 to abut against the side of the housing 2. At this point, the housing 1 continues to be pushed closer to the housing 2, causing the sealing strip 12 to continue moving towards the housing 2. The sealing strip 12 is then compressed by the side of the housing 2, causing the seal to... When the sealing strip 12 deforms and moves to be directly opposite the sealing groove 241, the sealing strip 12 returns to its original shape through its own deformation, so that the surface of the sealing strip 12 abuts against the inside of the sealing groove 241. At the same time, the sealing frame 14 enters the inside of the frame groove 26, and the surface of the sealing frame 14 abuts against the inner wall of the frame groove 26. Thus, the joint between the housing 1 and the housing 2 is sealed by the insert frame 11, the sealing strip 12, and the sealing frame 14, preventing coolant from entering the inside of the housing 1 and the housing 2 and from leaking out.

[0065] Reference Figures 1-12 The interior of the enclosure 1 is provided with a conduit 7 for installing electrical wiring. The conduit 7 includes a mounting plate 71 fixed inside the enclosure 1 and arranged vertically. Multiple circuit breakers 72 are fixed on the surface of the mounting plate 71. Each circuit breaker 72 includes an inlet end and an outlet end. Both the inlet end and the outlet end include a sub-hole and a screw for fixing the wiring. The circuit breaker 72 is an existing and mature technology. The principle of the circuit breaker 72 will not be described in detail. The two terminal holes of the circuit breaker 72 are used to insert wire bodies 74. The wire bodies 74 are positioned in the sub-hole by the screws at the inlet end and the outlet end, thereby realizing the connection between the wire bodies 74 and the circuit breaker 72.

[0066] A sleeve 73 is fitted onto the surface of the wire body 74. The surface of the wire body 74 abuts against the inner wall of the sleeve 73. The distance (i.e., thickness) between the inner and outer surfaces of the sleeve 73 is 0.5-2mm. The inner diameter of the sleeve 73 is 15mm-25mm. The specific inner diameter can be customized according to actual needs. Both sides of the surface of the first box 1 and the second box 2 are provided with through holes 8 for the sleeve 73 to pass through. The surface of the sleeve 73 abuts against the inner wall of the through holes 8. At least two sealing rings 731 are fixed on the surface of the sleeve 73 to seal the sleeve 73 with the wire inlet of the first box 1 and the second box 2. One side of the surface of the first box 1 and the second box 2 is provided with annular grooves 251 equal in number to the sleeve 73. The surface of the sealing rings 731 abuts against the inner wall of the annular grooves 251, so that the sealing rings 731 can seal the sleeve 73 with the first box 1 and the second box 2.

[0067] At least two limiting brackets 75 located at both ends of the circuit breaker 72 are fixed on the surface of the mounting plate 71. The surface of the limiting bracket 75 is T-shaped. The surface of the sleeve 73 abuts against the surface of the limiting bracket 75 away from the mounting plate 71. The sleeve 73 is limited to the surface of the limiting bracket 75 away from the mounting plate 71 by steel nail clamps. When the wire body 74 is too long, the central part of the sleeve 73 is limited to the surface of the mounting plate 71 by steel nail clamps, so that the entire sleeve 73 is U-shaped.

[0068] It should be noted that when the wire body 74 and the sleeve 73 are installed inside the housing 1, the end of the wire body 74 and the sleeve 73 away from the circuit breaker 72 should protrude through the hole 8 to facilitate the subsequent connection of related electrical components.

[0069] Multiple wire bodies 74 can be centrally installed inside the housing 1 through the sleeve 73 and the limiting bracket 75, thereby achieving centralized temperature control of the electrical circuit.

[0070] It should be noted that: Box 1, Box 2, and Temperature Control Box 51 are made of ABS engineering plastic; Sealing plug 21 is made of silicone; Sealing frame 14, Insert frame 11, Sealing strip 12, Sealing ring 1 531, and Sealing ring 2 731 are all made of nitrile rubber; Sleeve 73 and Temperature Control tube 53 are both made of copper; Divider 6 is made of glass fiber reinforced plastic, with the outer layer made of hot-dip galvanized steel strip and the inner wall being an insulating resin layer; Mounting plate 71 and Limiting frame 75 are made of calcium silicate, and the surfaces of mounting plate 71 and Limiting frame 75 are provided with anti-slip texture (not shown in the figure).

[0071] The coolant used is an aqueous solution of ethylene glycol or mineral oil, with the concentration of the aqueous solution of ethylene glycol being 40%-50%.

[0072] Centrifugal pump 32 adopts the ISG vertical series, temperature sensor 22 adopts the HG35 series platinum resistance thermometer, and fan 52 adopts the 200FZY4-D series, with a rated power of 15W-30W and an air volume of 500m³. 3 / h-1500m 3 / h, with a rotational speed of 2000RPM-3000RPM.

[0073] Before this application is used, the wire body 74 has been installed inside the housing 1 using the above installation method. The housing 1 and the housing 2 are in a separated state, and there is no coolant inside the temperature control chamber 13 and the temperature control chamber 23.

[0074] The implementation principle of the electrical circuit temperature control device for fire prevention in a tobacco logistics park according to this application embodiment is as follows: In use, the drive block 43 is first manually rotated counterclockwise to provide power to the positioning column 431, causing the drive block 43 to rotate the positioning column 431 counterclockwise, thus moving the positioning column 431 upwards along the thread. When the end of the positioning column 431 away from the drive block 43 is moved to the same horizontal line as the top wall of the positioning groove 421, or when the positioning column 431 is moved to the inside of the positioning seat 42 on the side away from the surface of the housing 2, the positioning block 41 on the housing 1 is aligned with the positioning groove 421 and pushed in the direction closer to the housing 2. Box 1 is brought close to Box 2. Box 1 moves the positioning block 41 close to the positioning seat 42, thereby inserting the positioning block 41 into the positioning groove 421. When Box 1 and Box 2 come into contact, the surface of the positioning block 41 near the positioning seat 42 abuts against the side wall of the positioning groove 421. The drive block 43 is rotated clockwise, causing the drive block 43 to rotate the positioning column 431 clockwise, causing the positioning column 431 to move downward, so that the end of the positioning column 431 away from the drive block 43 is inserted into the drive groove 411, thereby fixing the positioning block 41 and the positioning seat 42 together, thus completing the fixing of Box 1 and Box 2.

[0075] As the housing 1 approaches the housing 2, the insert frame 11 gradually inserts into the slot 24. During this process, the insert frame 11 moves the sealing strip 12 closer to the housing 2, causing the side of the sealing strip 12 away from the housing 1 to abut against the side of the housing 2. At this point, the housing 1 continues to be pushed closer to the housing 2, causing the sealing strip 12 to move further towards the housing 2. The sealing strip 12 is then compressed by the side of the housing 2, causing it to deform. When the sealing strip 12 moves to be directly opposite the sealing groove 241, the sealing strip 12 returns to its original shape through its own deformation, so that the surface of the sealing strip 12 abuts against the inside of the sealing groove 241. At the same time, when the housing 1 approaches the housing 2, the sealing frame 14 is driven to gradually enter the frame groove 26, so that the surface of the sealing frame 14 abuts against the inner wall of the frame groove 26. Thus, the joint between the housing 1 and the housing 2 is sealed by the insert frame 11, the sealing strip 12, and the sealing frame 14, preventing coolant from entering the interior of the housing 1 and the housing 2 and from leaking out.

[0076] Manually rotate the sealing plug 21 counterclockwise to move it upwards along the thread, gradually separating it from the surface of the housing 2. Once the sealing plug 21 is completely separated from the surface of the housing 2, the user injects coolant into the temperature control chamber 23 through the connection between the sealing plug 21 and the housing 2. When the user visually observes that the coolant level in the temperature control chamber 23 is level with or slightly off the top wall of the temperature control chamber 23, stop injecting coolant and rotate the sealing plug 21 clockwise to re-fix it onto the surface of the housing 2, thus re-sealing the connection between the sealing plug 21 and the housing 2.

[0077] When the power supply to the centrifugal pump 32 is turned on, the centrifugal pump 32 starts to work. The centrifugal pump 32 provides power to the inlet pipe 33 and the outlet pipe 34, so that the inlet pipe 33 introduces the coolant in the temperature control chamber 23 into the interior of the inlet pipe 33. Then, the coolant is introduced from the interior of the inlet pipe 33 into the interior of the outlet pipe 34. The coolant is then guided back into the temperature control chamber 23 through the outlet pipe 34, so that the coolant inside the temperature control chamber 23 is in a flowing state, thereby better controlling the temperature of the electrical circuits inside the first chamber 1 and the second chamber 2.

[0078] Temperature sensor 22 monitors the temperature of the electrical circuit. When the temperature is too high, temperature sensor 22 controls fan 52 to start, causing fan 52 to generate airflow. The airflow flows into the temperature control tube 53 near the temperature control box 51. During the flow of airflow inside the temperature control tube 53, it is cooled by coolant. The cooled airflow then cools the sleeve 73 on the surface of the wire body 74, thereby controlling the temperature of the wire body 74. The airflow is discharged from the interior of box 1 and box 2 through the temperature control tube 53 away from the temperature control box 51, preventing hot air from entering the interior of box 1 and box 2.

[0079] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
