Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a box-type transformer with constant temperature control. Background Technology

[0002] A prefabricated box-type transformer is a compact, complete substation that integrates high-voltage switches, transformers, and low-voltage power distribution equipment into a single enclosed enclosure. It is essentially a portable, prefabricated small power distribution room. With continuous technological advancements and rapid societal progress, the application of prefabricated box-type transformers is increasing. They are widely used in residential communities, commercial centers, light industrial stations, airports, factories, mines, enterprises, hospitals, schools, and other locations.

[0003] For example, Chinese Patent Publication No. CN211790297U describes a high-safety box-type transformer with intelligent temperature dissipation, including a transformer roof structure, a transformer main structure, a bottom heat dissipation structure, a water-cooling structure, a louvered heat dissipation structure, and fixed casters. The transformer roof structure includes a conical roof with ceiling-mounted lighting on the inner surface. At least four sets of L-shaped ventilation ducts are fixed to the top of the conical roof surface, and each L-shaped ventilation duct has a top exhaust fan at its bottom. The outlets of the L-shaped ventilation ducts are equipped with dust filters, and the outlet pipes have internal threads. The conical roof design provides waterproofing, and the exhaust fans greatly enhance heat dissipation, meeting daily cooling requirements. To meet the heat dissipation requirements of the transformer substation, stable and long-lasting heat dissipation is achieved. The water-cooled structure includes a bottom insulating plate with reinforcing ribs on its lower surface. A transformer mounting base is fixedly connected to the upper surface of the bottom insulating plate, housing a transformer with a temperature sensor next to it. A water-cooling chamber surrounds the bottom insulating plate, containing water-cooling pipes. A condenser and a pressure pump are threaded through the water-cooling pipes. The input terminals of the condenser and pressure pump are electrically connected to the output terminal of an external PLC. In case of transformer substation failure, manual on-site maintenance is required. The water-cooled bottom design greatly alleviates the heat for workers and can also work with other heat dissipation systems to achieve rapid heat dissipation.

[0004] In existing technology citations, heat dissipation can be achieved through condensers and pressure pumps. However, with such a design, the heat generated by electrical components is difficult to dissipate in a confined space. At the same time, condensation droplets easily form on the condenser when exposed to hot air, making it inconvenient to deal with the condensation droplets. Summary of the Invention

[0005] To solve the above technical problems, the present invention is implemented through the following technical solution: A temperature-controlled box-type transformer, comprising: The bottom shell and the box body fixedly installed on the top of the bottom shell, a controller is fixedly installed on the inner wall of the box body near the top, a thermocouple temperature sensor is fixedly installed on the inner wall of the box body near the controller, and a power conversion mechanism is installed between the bottom of the inner cavity of the box body and the bottom of the inner cavity of the bottom shell. The cooling mechanism includes a blower and a bent water collection trough. The blower is fixedly installed on the side of the bottom of the inner cavity of the bottom shell. The bent water collection trough is fixedly installed at the bottom of the inner cavity of the box. A rectangular air duct is fixedly installed inside the bent water collection trough. A drain pipe is connected to the bottom of the bent water collection trough and near the blower. An exhaust assembly is installed at the top of the rectangular air duct and near the box door on the surface of the box. The exhaust assembly includes a hook-shaped exhaust duct and an elastic membrane. The air inlet at the bottom of the hook-shaped exhaust duct is connected to the air outlet at the top of the rectangular duct. The elastic membrane is fixedly connected to the bend at the top of the hook-shaped exhaust duct. A conical air nozzle is fixedly installed on the surface of the hook-shaped exhaust duct, and an elastic baffle is fixedly connected to the air inlet inside the conical air nozzle. When the temperature inside the chamber rises, heat is transferred to the surrounding rectangular duct using the principle of heat transfer. A thermocouple temperature sensor monitors and collects the temperature inside the chamber. The temperature sensor transmits the collected temperature information to the controller in the form of an electrical signal. The controller receives and processes the electrical signal. When it detects that the temperature inside the chamber exceeds the set value, it indicates that the temperature inside the chamber is too high. The controller then controls the blower to turn on the blower. The blower's force causes the air inside the rectangular air duct to be blown. The air flows into the hook-shaped exhaust duct and is discharged from the air outlet at the top of the hook-shaped exhaust duct. This creates air circulation, which promptly removes heat and helps dissipate heat from inside the chamber. A shielding mechanism is installed on the top of the box.

[0006] Furthermore, the rectangular air duct and the bent water collection trough are both installed around the inside of the housing, and the air outlet at the top of the blower is connected to the air inlet at the bottom of the rectangular air duct.

[0007] Furthermore, there are two drain pipes, which are symmetrically installed along the central axis of the rectangular duct. The outlet end of the drain pipe penetrates the inner wall of the bottom shell and extends to its outside. The middle of the drain pipe is arc-shaped. As the gas in the rectangular duct and the hook-shaped exhaust pipe flows rapidly, and the inner diameter of the hook-shaped exhaust pipe is larger than the inner diameter of the conical nozzle, and is blocked by the elastic baffle, the gas resistance in the conical nozzle is greater than the gas resistance in the hook-shaped exhaust pipe. This allows the gas in the hook-shaped exhaust pipe to flow upward smoothly. At the same time, the rapid flow of gas in the hook-shaped exhaust pipe creates suction in the conical nozzle, causing the air inside the box to pass through the two symmetrical elastic baffles inside the conical nozzle. The hot air from inside the box enters the conical nozzle and merges with the airflow in the hook-shaped exhaust pipe, thereby absorbing heat from inside the box and accelerating the cooling of the box.

[0008] Furthermore, the thermocouple temperature sensor is electrically connected to the controller, and the blower is electrically connected to the controller. Initially, because the electrical components are installed at the bottom of the housing cavity, the housing and electrical components form a single unit. The temperature of the inner wall of the housing is slightly higher than the surface temperature of the hook-shaped exhaust duct and the rectangular duct, making condensation less likely to occur on the inner wall. The hook-shaped exhaust duct and the rectangular duct have no contact with the electrical components, and the surface temperature of the hook-shaped exhaust duct and the rectangular duct is slightly lower than the air temperature inside the housing. This is accompanied by the... The operation causes the temperature inside the chamber to rise. When the surface of the hook-shaped exhaust duct and the rectangular duct comes into contact with the hot air inside the chamber, condensation forms. This condensation flows down the hook-shaped exhaust duct and the rectangular duct into the bent water collection tank, where it is collected. As the amount of condensation in the bent water collection tank increases, the condensation is discharged through the drain pipe under liquid pressure. The drain pipe is treated by a curved bend in the middle, ensuring that there is always water at the curved bend. This seals the drain pipe, preventing insects from entering the chamber through the drain pipe.

[0009] Furthermore, the hook-shaped exhaust duct is installed vertically, and the air outlet at the top of the hook-shaped exhaust duct penetrates the top of the inner side of the box and extends to its outside. The air outlet at the top of the hook-shaped exhaust duct faces downward, and the conical air nozzles are evenly distributed on the surface of the hook-shaped exhaust duct.

[0010] Furthermore, the shielding mechanism includes a bracket and an opening / closing baffle. The top of the bracket is fixedly installed to the top of the inner cavity of the housing. The opening / closing baffle is hinged to the side of the top of the housing. An electric telescopic rod is hinged to the bottom of the bracket. The electric telescopic rod is electrically connected to a controller. The telescopic end of the electric telescopic rod is hinged to the bottom of the opening / closing baffle. A limiting square rod is fixedly connected to the side of the bottom of the opening / closing baffle. A pressing round rod is fixedly connected to the bottom of the limiting square rod. A rainproof component is installed between the top of the housing and the surface of the opening / closing baffle. The controller is used to control... The electric telescopic rod is controlled to retract, and its extension end applies a pulling force to the opening and closing baffle, causing the baffle to cover the top of the enclosure. When the baffle is closed, it provides rain protection. The C-shaped sealing gasket is pressed by the baffle, ensuring it fits tightly between the bottom edge of the baffle and the top of the enclosure. Simultaneously, the herringbone cover and the water-repellent membrane prevent splashing rainwater from entering the enclosure. Furthermore, during the rainy season, when temperatures are low, the internal temperature of the enclosure is also low, preventing the baffle from opening.

[0011] Furthermore, the rainproof component includes a herringbone-shaped cover and a C-shaped sealing gasket. The herringbone-shaped cover is fixedly installed at the middle of the top of the box, and the C-shaped sealing gasket is fixedly installed at the bottom side of the opening and closing baffle. A baffle plate is fixedly installed on the side of the inner side of the herringbone-shaped cover, and a water-resistant membrane is fixedly connected between the inner side of the herringbone-shaped cover and the top of the opening and closing baffle, near the baffle plate.

[0012] Under sunlight, the temperature inside the chamber rises. The extension of the electric telescopic rod applies an upward force to the opening and closing baffles, causing the symmetrical baffles on both sides to rotate outwards, opening them to facilitate the dissipation of hot air from inside the chamber. The opening and closing baffles also cause the limiting rod to rotate outwards, adjusting its angle so that the pressing rod contacts the elastic diaphragm. This not only controls the opening angle of the baffles by limiting the pressing rod, but also causes the elastic diaphragm to deform elastically, reducing the diameter of the gas flow opening in the hook-shaped exhaust duct and increasing the gas flow speed, further promoting heat dissipation.

[0013] Furthermore, the C-shaped sealing gasket is made of rubber, there are four baffles, and the four baffles are evenly distributed on the sides of the inner side of the herringbone-shaped cover, and the surface of the water-blocking membrane is a wavy curved surface.

[0014] Furthermore, the transformer mechanism includes a transformer body and a liquid storage tank. The transformer body is fixedly installed at the bottom of the inner cavity of the tank, and the liquid storage tank is fixedly installed at the bottom of the inner cavity of the bottom shell. A pump body is fixedly installed on the side of the surface of the liquid storage tank. The pump body is electrically connected to the controller. The liquid outlet at the top of the pump body is connected to a rectangular condenser tube. A heat-conducting plate is fixedly connected to the surface of the transformer body. The surface of the heat-conducting plate has strip grooves. The heat-conducting plate can conduct heat generated by the transformer body. Through the suction of the pump body, the coolant in the liquid storage tank is drawn out and transported to the inside of the rectangular condenser tube. Under the principle of heat transfer, the heat conducted by the heat-conducting plate to the transformer body is absorbed by the coolant in the rectangular condenser tube. Combined with the fact that the coolant in the rectangular condenser tube flows back to the liquid storage tank, a reciprocating cycle is formed, which accelerates the absorption of heat from the heat-conducting plate and thus cools the transformer body.

[0015] Furthermore, the heat-conducting plate is evenly distributed on the surface of the transformer body, the bottom end of the heat-conducting plate penetrates the bottom of the inner cavity of the tank and extends into the interior of the bottom shell, the bottom end of the heat-conducting plate is fixedly connected to the top of the rectangular condenser tube, the strip groove is evenly distributed on the surface of the heat-conducting plate, and the liquid outlet of the rectangular condenser tube is connected to the liquid inlet on the surface of the liquid storage tank.

[0016] The beneficial effects of the technical solution provided by this invention include: 1. Utilizing the principle of heat transfer, heat inside the enclosure is transferred to the surrounding rectangular air duct. When the temperature inside the enclosure exceeds the set value, it indicates that the temperature inside the enclosure is too high. The airflow of the blower causes the air inside the rectangular air duct to be blown out and enters the hook-shaped exhaust duct along with the air flow inside the rectangular air duct. It is then discharged from the air outlet at the top of the hook-shaped exhaust duct, thus forming air circulation and timely carrying away the heat, which helps to dissipate the heat inside the enclosure and maintain a constant temperature inside the enclosure.

[0017] 2. As the gas flows rapidly within the rectangular duct and hook-shaped exhaust pipe, and is blocked by the elastic baffles, the gas resistance within the conical nozzle is greater than that within the hook-shaped exhaust pipe. This allows the gas in the hook-shaped exhaust pipe to flow upwards smoothly. Simultaneously, the rapid flow of gas within the hook-shaped exhaust pipe creates suction within the conical nozzle, causing the air inside the chamber to pass through the two symmetrical elastic baffles within the conical nozzle. The hot air entering the conical nozzle from inside the chamber merges with the airflow within the hook-shaped exhaust pipe, thereby drawing out heat from inside the chamber and accelerating the cooling process.

[0018] 3. The surface temperature of the hook-shaped exhaust duct and the rectangular duct is slightly lower than the air temperature inside the enclosure. As the components inside the enclosure operate, the temperature inside the enclosure rises. When the surface of the hook-shaped exhaust duct and the rectangular duct comes into contact with the hot air inside the enclosure, condensation droplets form. These droplets flow down the hook-shaped exhaust duct and the rectangular duct into the bent water collection trough for collection. As the amount of condensate in the bent water collection trough increases, under the action of liquid pressure, the condensate is discharged through the drain pipe for treatment.

[0019] 4. The telescopic end of the electric telescopic rod applies a pulling force to the opening and closing baffle, causing the baffle to cover the top of the box. When the baffle is closed, it can block rain. The C-shaped sealing gasket is pressed by the opening and closing baffle, so that the C-shaped sealing gasket fits tightly between the bottom edge of the opening and closing baffle and the top of the box. At the same time, under the cover of the herringbone cover, and with the water-repellent membrane blocking splashing rainwater, it can prevent outside rainwater from entering the interior of the box.

[0020] 5. The telescopic end of the electric telescopic rod applies an upward pushing force to the opening and closing baffles, causing the symmetrical opening and closing baffles on both sides to rotate outwards, opening the baffles to facilitate the dissipation of hot air inside the chamber. The opening and closing baffles also drive the limiting square rod to rotate outwards to adjust the angle, so that the pressing round rod contacts the elastic membrane. This not only allows the opening angle of the opening and closing baffles to be controlled by limiting the pressing round rod, but also causes the elastic membrane to deform elastically by pressing the pressing round rod. This reduces the gas flow diameter in the hook-shaped exhaust duct, which increases the gas flow speed and further promotes the dissipation of heat.

[0021] VI. The heat-conducting plate can conduct heat away from the transformer body. The pump body draws out the coolant from the storage tank and delivers it to the inside of the rectangular condenser tube. Under the principle of heat transfer, the heat conducted by the heat-conducting plate to the transformer body is absorbed by the coolant in the rectangular condenser tube. The coolant in the rectangular condenser tube will flow back into the storage tank, forming a reciprocating cycle, which accelerates the absorption of heat from the heat-conducting plate and thus cools the transformer body.

[0024] Example 1, see Figures 1-5 A technical solution is provided: A temperature-controlled box-type transformer, comprising: The bottom shell 1 and the box 2 fixedly installed on the top of the bottom shell 1. A controller 3 is fixedly installed on the inner wall of the box 2 near the top. A thermocouple temperature sensor 4 is fixedly installed on the inner wall of the box 2 near the controller 3. A transformer mechanism 5 is installed between the bottom of the inner cavity of the box 2 and the bottom of the inner cavity of the bottom shell 1. Cooling mechanism 6 includes a blower 61 and a bent water receiving trough 62. The blower 61 is fixedly installed on the side of the bottom of the inner cavity of the bottom shell 1. The bent water receiving trough 62 is fixedly installed on the bottom of the inner cavity of the box 2. A rectangular air duct 63 is suspended and fixedly installed inside the bent water receiving trough 62. A drain pipe 64 is connected to the bottom of the bent water receiving trough 62 and near the blower 61. An exhaust component 65 is installed on the top of the rectangular air duct 63 and near the box door on the surface of the box 2. The rectangular air duct 63 and the bent water receiving trough 62 are both installed in a ring around the inside of the housing 2, and the air outlet at the top of the blower 61 is connected to the air inlet at the bottom of the rectangular air duct 63. There are two drain pipes 64, and the two drain pipes 64 are symmetrically installed along the central axis of the rectangular air duct 63. The outlet end of the drain pipe 64 penetrates the inner wall of the bottom shell 1 and extends to its outside. The middle part of the drain pipe 64 is arc-shaped. Thermocouple temperature sensor 4 is electrically connected to controller 3, and hair dryer 61 is electrically connected to controller 3. The exhaust assembly 65 includes a hook-shaped exhaust duct 651 and an elastic membrane 652. The air inlet at the bottom of the hook-shaped exhaust duct 651 is connected to the air outlet at the top of the rectangular duct 63. The elastic membrane 652 is fixedly connected to the bend at the top of the hook-shaped exhaust duct 651. A conical air nozzle 653 is fixedly installed on the surface of the hook-shaped exhaust duct 651. An elastic baffle 654 is fixedly connected to the air inlet inside the conical air nozzle 653. When the temperature inside the housing 2 rises, heat is transferred from the housing 2 to the surrounding rectangular duct 63 using the principle of heat transfer. A thermocouple-type temperature sensor 4 monitors and collects the temperature inside the housing 2. Temperature sensor 4 transmits the collected temperature information to controller 3 in the form of an electrical signal. Controller 3 receives and processes the electrical signal. When it detects that the temperature inside the chamber 2 exceeds the set value, it indicates that the temperature inside the chamber 2 is too high. Controller 3 then controls the blower 61 to start working. The blowing force of the blower 61 causes the air inside the rectangular air duct 63 to be blown. The air flows into the hook-shaped exhaust pipe 651 and is discharged from the air outlet at the top of the hook-shaped exhaust pipe 651, thus forming air circulation and timely removing heat, which helps to dissipate heat inside the chamber 2. The hook-shaped exhaust duct 651 is installed vertically. The air outlet at the top of the hook-shaped exhaust duct 651 penetrates the top of the inner side of the housing 2 and extends to its exterior. The air outlet at the top of the hook-shaped exhaust duct 651 faces downward. Conical air nozzles 653 are evenly distributed on the surface of the hook-shaped exhaust duct 651. As the gas flows rapidly in the rectangular duct 63 and the hook-shaped exhaust duct 651, and given that the inner diameter of the hook-shaped exhaust duct 651 is larger than the inner diameter of the conical air nozzles 653, and under the obstruction of the elastic baffle 654, the gas inside the conical air nozzles 653... The gas resistance is greater than the gas resistance inside the hook-shaped exhaust duct 651, allowing the gas inside the hook-shaped exhaust duct 651 to flow upward smoothly. At the same time, the rapid flow of gas inside the hook-shaped exhaust duct 651 creates suction inside the conical air nozzle 653, causing the air inside the box 2 to pass through the two symmetrical elastic baffles 654 inside the conical air nozzle 653. The hot air from inside the box 2 enters the conical air nozzle 653 and merges with the airflow inside the hook-shaped exhaust duct 651, thereby absorbing the heat from inside the box 2 and accelerating the cooling of the box 2.

[0025] Initially, because the electrical components are installed at the bottom of the inner cavity of the enclosure 2, the enclosure 2 and the electrical components are integrated. The temperature of the inner wall of the enclosure 2 is slightly higher than the surface temperature of the hook-shaped exhaust duct 651 and the rectangular duct 63, making it less prone to condensation. The hook-shaped exhaust duct 651 and the rectangular duct 63 have no contact with the electrical components, and their surface temperatures are slightly lower than the air temperature inside the enclosure 2. As the components in the enclosure 2 operate, the temperature inside the enclosure 2 rises, and the hook-shaped exhaust duct 651... When the surface of the air duct 63 comes into contact with the hot air inside the housing 2, condensation droplets form. These droplets then flow down the hook-shaped exhaust duct 651 and the rectangular duct 63 into the bent water collection trough 62, where they are collected. As the amount of condensate in the bent water collection trough 62 increases, it is discharged through the drain pipe 64 under liquid pressure. The drain pipe 64 is designed to treat the condensate, and its curved bend in the middle ensures that there is always water at the bend. This seals the drain pipe 64 to prevent insects from entering the housing 2 through it.

[0026] Example 2, based on Example 1, see [link / reference] Figures 1 to 7 A technical solution is provided: A shielding mechanism 7 is installed on the top of the housing 2.

[0027] The shielding mechanism 7 includes a bracket 71 and an opening / closing baffle 72. The top of the bracket 71 is fixedly installed to the top of the inner cavity of the housing 2. The opening / closing baffle 72 is hinged to the side of the top of the housing 2. An electric telescopic rod 73 is hinged to the bottom of the bracket 71. The electric telescopic rod 73 is electrically connected to the controller 3. The telescopic end of the electric telescopic rod 73 is hinged to the bottom of the opening / closing baffle 72. A limiting square rod 74 is fixedly connected to the side of the bottom of the opening / closing baffle 72. A pressing round rod 75 is fixedly connected to the bottom of the limiting square rod 74. A rainproof component 76 is installed between the top of the housing 2 and the surface of the opening / closing baffle 72.

[0028] The rainproof component 76 includes a herringbone-shaped cover 761 and a C-shaped sealing gasket 762. The herringbone-shaped cover 761 is fixedly installed at the middle of the top of the housing 2, and the C-shaped sealing gasket 762 is fixedly installed on the side of the bottom of the opening and closing baffle 72. A baffle plate 763 is fixedly installed on the side of the inner side of the herringbone-shaped cover 761. A water-resistant membrane 764 is fixedly connected between the inner side of the herringbone-shaped cover 761 and the top of the opening and closing baffle 72, near the baffle plate 763. When it rains, the controller 3 controls the electric telescopic rod 73 to retract it. The telescopic end applies a pulling force to the opening and closing baffle 72, causing the opening and closing baffle 72 to cover the top of the box 2. When the opening and closing baffle 72 is in the closed state, it can block rain. The C-shaped sealing gasket 762 is pressed by the opening and closing baffle 72, so that the C-shaped sealing gasket 762 is tightly attached between the bottom edge of the opening and closing baffle 72 and the top of the box 2. At the same time, under the cover of the herringbone cover 761 and the water-blocking membrane 764, splashing rainwater can be blocked, preventing external rainwater from entering the interior of the box 2. In addition, during the rainy season, the temperature is low, and the temperature inside the box 2 is also low, so the opening and closing baffle 72 will not open.

[0029] The C-shaped sealing gasket 762 is made of rubber. There are four baffles 763, which are evenly distributed on the inner side of the herringbone-shaped cover 761. The surface of the water-blocking membrane 764 is wavy. When it is sunny, the temperature inside the box 2 rises under sunlight. The extension end of the electric telescopic rod 73 applies an upward pushing force to the opening and closing baffle 72, causing the two symmetrical opening and closing baffles 72 to rotate outward, and the opening and closing baffles 72 are in the open state. This facilitates the dissipation of hot air inside the housing 2. The opening and closing baffle 72 will drive the limiting square rod 74 to rotate outward and adjust the angle, so that the pressing round rod 75 contacts the elastic membrane 652. Not only can the opening angle of the opening and closing baffle 72 be controlled by limiting the pressing round rod 75, but the pressing round rod 75 can also press the elastic membrane 652, causing the elastic membrane 652 to deform elastically. The gas flow diameter in the hook-shaped exhaust pipe 651 becomes smaller, which can increase the gas flow speed and further promote the dissipation of heat.

[0030] Example 3, based on Examples 1 and 2, see below. Figures 1 to 9 A technical solution is provided: The transformer mechanism 5 includes a transformer body 51 and a liquid storage tank 52. The transformer body 51 is fixedly installed at the bottom of the inner cavity of the housing 2, and the liquid storage tank 52 is fixedly installed at the bottom of the inner cavity of the bottom shell 1. A pump body 53 is fixedly installed on the side of the surface of the liquid storage tank 52. The pump body 53 is electrically connected to the controller 3. A rectangular condenser pipe 54 is connected to the liquid outlet at the top of the pump body 53. A heat-conducting plate 55 is fixedly connected to the surface of the transformer body 51. A strip groove 56 is opened on the surface of the heat-conducting plate 55.

[0031] The transformer body 51 is used for power conversion, and the transformer body 51 generates heat when it is working. The heat conduction plate 55 can conduct the heat generated by the transformer body 51. The pump body 53 is electrically controlled by the controller 3 to start the pump body 53. The pump body 53 draws out the coolant in the liquid storage tank 52 and delivers it to the inside of the rectangular condenser tube 54. Under the principle of heat transfer, the heat conducted by the heat conduction plate 55 to the transformer body 51 is absorbed by the coolant in the rectangular condenser tube 54. The coolant in the rectangular condenser tube 54 flows back to the liquid storage tank 52, forming a reciprocating cycle, which accelerates the absorption of heat by the heat conduction plate 55 and thus cools the transformer body 51.

[0032] Heat-conducting plates 55 are evenly distributed on the surface of the transformer body 51. The bottom end of the heat-conducting plates 55 penetrates the bottom of the inner cavity of the housing 2 and extends into the interior of the bottom shell 1. The bottom end of the heat-conducting plates 55 is fixedly connected to the top of the rectangular condenser tube 54. Strip grooves 56 are evenly distributed on the surface of the heat-conducting plates 55. The liquid outlet of the rectangular condenser tube 54 is connected to the liquid inlet on the surface of the liquid storage tank 52.

[0033] When in use, first install the box-type transformer consisting of the bottom shell 1 and the box body 2 in the designated position, and inject an appropriate amount of coolant into the liquid storage tank 52. Use the transformer body 51 to convert electricity. The transformer body 51 will generate heat when it is working. The heat conduction plate 55 can conduct the heat generated by the transformer body 51. Furthermore, when it rains, the controller 3 controls the electric telescopic rod 73 to retract it. The telescopic end of the electric telescopic rod 73 applies a pulling force to the opening and closing baffle 72, causing the opening and closing baffle 72 to cover the top of the box 2. When the opening and closing baffle 72 is in the closed state, it can block the rain. The C-shaped sealing gasket 762 is pressed by the opening and closing baffle 72, so that the C-shaped sealing gasket 762 is tightly attached between the bottom edge of the opening and closing baffle 72 and the top of the box 2. At the same time, under the cover of the herringbone cover 761 and the water-blocking membrane 764, splashing rainwater can be blocked, preventing external rainwater from entering the interior of the box 2. Also, during the rainy season, the temperature is low, and the temperature inside the box 2 is also low, so the opening and closing baffle 72 will not open. Initially, because the electrical components are installed at the bottom of the inner cavity of the enclosure 2, the enclosure 2 and the electrical components are integrated. The temperature of the inner wall of the enclosure 2 is slightly higher than the surface temperature of the hook-shaped exhaust duct 651 and the rectangular duct 63, making it less prone to condensation. The hook-shaped exhaust duct 651 and the rectangular duct 63 have no contact with the electrical components, and their surface temperatures are slightly lower than the air temperature inside the enclosure 2. As the components in the enclosure 2 operate, the temperature inside the enclosure 2 rises, and the hook-shaped exhaust duct 651... When the surface of the air duct 63 comes into contact with the hot air inside the housing 2, condensation droplets will form. These droplets will then flow down the hook-shaped exhaust pipe 651 and the rectangular duct 63 into the bent water collection trough 62, where they will be collected. As the amount of condensate in the bent water collection trough 62 increases, it will be discharged through the drain pipe 64 under liquid pressure. The drain pipe 64 is designed to treat the condensate, and its middle section is curved to ensure that there is always water at the curved section. This will seal the drain pipe 64 and prevent insects from entering the housing 2 through it. When the sun shines, the temperature inside the enclosure 2 rises. Utilizing the principle of heat transfer, the heat inside the enclosure 2 is transferred to the surrounding rectangular duct 63. Thermocouple temperature sensor 4 monitors and collects the temperature inside the enclosure 2, transmitting the collected temperature information to controller 3 in the form of an electrical signal. Controller 3 receives and processes the electrical signal. If it detects that the temperature inside the enclosure 2 exceeds the set value, it indicates that the temperature inside the enclosure 2 is too high. Controller 3 then controls the blower 61, turning it on. The blowing force of the blower 61 causes the air inside the rectangular duct 63 to be blown. The air flows into the hook-shaped exhaust pipe 651 and is discharged from the outlet at the top of the hook-shaped exhaust pipe 651, thus creating air circulation and promptly carrying away the heat, which helps dissipate the heat inside the enclosure 2. Furthermore, the controller 3 controls the electric telescopic rod 73. The extension of the telescopic end of the electric telescopic rod 73 applies an upward pushing force to the opening and closing baffle 72, causing the two symmetrical opening and closing baffles 72 to rotate outward, so that the opening and closing baffles 72 are in an open state, which facilitates the dissipation of hot air inside the box 2. The opening and closing baffles 72 will also drive the limiting square rod 74 to rotate outward together to adjust the angle, so that the pressing round rod 75 contacts the elastic membrane 652. The opening angle of the opening and closing baffles 72 can be controlled by limiting the pressing round rod 75. Furthermore, as the gas flows rapidly within the rectangular duct 63 and the hook-shaped exhaust duct 651, and given that the inner diameter of the hook-shaped exhaust duct 651 is larger than the inner diameter of the conical nozzle 653, and under the obstruction of the elastic baffle 654, the gas resistance within the conical nozzle 653 is greater than that within the hook-shaped exhaust duct 651. This allows the gas within the hook-shaped exhaust duct 651 to flow upwards smoothly. Simultaneously, the rapid flow of gas within the hook-shaped exhaust duct 651 creates suction within the conical nozzle 653, causing the air inside the housing 2 to pass through the two symmetrical elastic baffles 654 within the conical nozzle 653. The hot air entering the conical nozzle 653 from inside the housing 2 merges with the airflow within the hook-shaped exhaust duct 651, thereby drawing out heat from the housing 2 and accelerating the cooling of the housing 2. Furthermore, after the opening and closing baffle 72 is opened, the pressing rod 75 presses the elastic membrane 652, which causes the elastic membrane 652 to deform elastically. The gas flow diameter in the hook-shaped exhaust pipe 651 becomes smaller, which increases the gas flow speed and further promotes the dissipation of heat. After the heat is dissipated inside the box 2, the box 2 becomes a constant temperature state. Then, the controller 3 can control the electric telescopic rod 73 to retract and pull the opening and closing baffle 72 to close it.
