Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of temperature controller, and particularly relates to an embedded installation structure of a dry-type transformer temperature controller. BACKGROUND
[0002] In a power supply system, the dry-type transformer has been widely applied in high-rise buildings, commercial centers, airports, chemical plants, nuclear power plants, industrial and mining enterprises and other places with high requirements for fire and explosion prevention due to its excellent characteristics such as environmental protection, flame retardation, impact resistance and maintenance-free. In order to ensure the safe and normal operation of the dry-type transformer, a temperature controller is essential for detecting the temperature of the three-phase winding of the transformer. The temperature controller can detect the winding temperature to determine whether to start and stop the cooling fan of the transformer, and can issue an audible and visual alarm in the case of over-temperature and cut off the output of the transformer in the extreme case to ensure the safety of the transformer and the power supply circuit.
[0003] In the field of dry-type transformer temperature controller, the embedded installation structure has obvious operation advantages, such as convenient on-site operation (key, switch) and intuitive display content viewing, but the embedded dry-type transformer temperature controller has certain technical defects:
[0004] Firstly, in the embedded installation structure, the temperature controller is usually embedded in the inside of the power distribution cabinet, resulting in limited space. This closed environment is easy to cause heat accumulation because the air circulation is not smooth, and the heat generated by the internal electronic components (such as the control panel) cannot be dissipated in time. The long-term accumulation of heat will accelerate the aging of the components, affecting the service life and reliability of the temperature controller.
[0005] Secondly, the existing heat dissipation technology (such as single air cooling scheme) is inefficient and difficult to meet the heat management needs in high load operation. Single air cooling only relies on the forced air flow of the fan, but in the embedded structure, the heat exchange efficiency is not high, and the core components cannot be fully cooled, which is particularly prominent in high load scenarios (such as continuous operation of the transformer), which may cause controller failure or false alarm.
[0006] Thirdly, when the temperature controller is embedded in the power distribution cabinet, the narrow space limits the layout and optimization of the heat dissipation module. Traditional heat dissipation components (such as fans or cooling pipes) are difficult to install without interfering with other devices, increasing the design complexity. The space limitation also prevents the heat dissipation module from integrating efficient cooling mechanisms (such as liquid cooling or composite heat dissipation). For example, the single scheme cannot take into account the synergistic effect of air cooling and liquid cooling, resulting in poor overall heat dissipation effect, which cannot meet the demand for compact and high-performance devices in modern power distribution systems.

Detailed Implementation
[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0034] This application discloses an embedded mounting structure for a dry-type transformer temperature controller. Please refer to [link / reference]. Figure 1 and Figure 4 An embedded installation structure for a dry-type transformer temperature controller includes a housing 1 embedded inside a distribution cabinet 100. A control panel 4 is fixedly connected to one end of the housing 1. Several evenly distributed ventilation holes 6 are provided at both the top and bottom ends of the housing 1. A heat dissipation module 7 is provided inside the housing 1. The heat dissipation module 7 includes a heat dissipation box 71 fixedly connected inside the housing 1. Several heat-conducting fins 72 are fixedly installed on the side of the heat dissipation box 71 near the control panel 4. The heat-conducting fins 72 are evenly distributed in the vertical direction. A motor 73 is fixedly installed on the outer wall of the heat dissipation box 71. An air-cooling component 74 is provided at the top of the heat dissipation box 71 to draw in external air in conjunction with the start of the motor 73. A liquid-cooling component 75 for cooling the air is provided inside the heat dissipation box 71. An air guide component 76 for exhausting the air inside the heat dissipation box 71 is provided at the bottom of the heat dissipation box 71.
[0035] By directly embedding the housing 1 of the temperature controller into the inside of the distribution cabinet 100, the temperature controller is smoothly integrated with the cabinet surface, facilitating on-site operation (buttons, switches) and intuitive viewing of the display content. During operation, the starting motor 73 drives the air-cooling component 74 to draw air from inside the housing 1 into the heat sink 71, creating a negative pressure state at the ventilation hole 6 at the top of the housing 1. This forces air from outside the housing 1 into the housing, greatly enhancing the ventilation effect inside the housing 1 and promoting rapid heat dissipation. The liquid cooling component 75 cools the air inside the heat sink 71, and the air guide component 76 then expels the cold air from inside the heat sink 71. The cold air quickly diffuses and cools the electronic components of the control panel 4, further improving the heat dissipation effect of the control panel 4. The heat-conducting plate 72 is designed to directly transfer the heat from the area where the electronic components are located to the heat sink 71 for cooling, further improving heat dissipation efficiency. The entire structure achieves efficient heat dissipation after the temperature controller is embedded in the distribution cabinet 100, solving the problem of heat accumulation in the embedded temperature controller leading to damage to the internal electronic components due to insufficient heat dissipation.
[0036] Please see Figures 1-5The air-cooled assembly 74 includes a mounting bracket 741 fixedly connected to the inner top wall of the heat sink 71. A suction impeller 742 is rotatably connected to the top of the mounting bracket 741, and a protective box 743 is fixedly connected to the bottom of the mounting bracket 741. A drive shaft 745 is rotatably connected to the inner side of the protective box 743 and passes through the protective box 743. One end of the drive shaft 745 is fixedly connected to the output shaft of the motor 73. A first bevel gear 744 is coaxially fixedly connected to the suction impeller 742. A second bevel gear 746 that meshes with the first bevel gear 744 is fixedly connected to the drive shaft 745. The gear ratio of the first bevel gear 744 to the second bevel gear 746 is 1:10.
[0037] Air cooling process: The starting motor 73 provides power to the drive shaft 745, causing the drive shaft 745 to rotate, which in turn causes the second bevel gear 746 to rotate synchronously. Since the first bevel gear 744 meshes with the second bevel gear 746 and their gear ratio is 1:10, the first bevel gear 744 will accelerate, thereby causing the suction impeller 742 to rotate at high speed. This puts the air inlet at the top of the heat sink 71 under negative pressure, drawing hot air from inside the housing 1 into the heat sink 71. This also puts the ventilation hole 6 at the top of the housing 1 under negative pressure, forcing air from outside the housing 1 into the housing 1. This greatly enhances the ventilation effect inside the housing 1 and facilitates rapid heat dissipation.
[0038] Please see Figure 1 and 7 The liquid cooling assembly 75 includes a cooling coil 751 fixedly connected to the inside of the heat sink 71. A coolant reservoir 752 is fixedly connected to the outside of the heat sink 71. An outlet pipe 753 is fixedly connected to the outlet end of the coolant reservoir 752. A negative pressure component 754 is provided at the outlet end of the outlet pipe 753. A delivery pipe 755 is connected to the outlet end of the negative pressure component 754. The outlet end of the delivery pipe 755 is connected to the inlet end of the cooling coil 751. A return pipe 756 is fixedly connected to the outlet end of the cooling coil 751. The outlet end of the return pipe 756 is connected to the inside of the coolant reservoir 752. The negative pressure component 754 includes a cylinder 7541 fixedly connected to the outer wall of the heat sink 71. The top of the cylinder 7541 is slidably connected to... A push-pull rod 7542 is connected to the top wall of the cylinder 7541. A piston 7543 is fixedly connected to the bottom of the push-pull rod 7542. The piston 7543 is slidably connected to the inner wall of the cylinder 7541. A liquid inlet check valve 7544 is fixedly connected to the inlet end of the cylinder 7541. The inlet end of the liquid inlet check valve 7544 is connected to the liquid outlet pipe 753. A liquid outlet check valve 7545 is fixedly connected to the outlet end of the cylinder 7541. The outlet end of the liquid outlet check valve 7545 is connected to the liquid delivery pipe 755. A connecting rod 7546 is hinged to the top of the push-pull rod 7542. An eccentric wheel 7547 is fixedly connected to one end of the drive shaft 745. The top end of the connecting rod 7546 is rotatably connected to the outer edge of the eccentric wheel 7547.
[0039] Liquid cooling process: When the motor 73 drives the main shaft 745 to rotate, the suction impeller 742 draws hot air from inside the housing 1 into the heat sink 71. Simultaneously, the main shaft 745 drives the eccentric wheel 7547 to rotate synchronously, causing the connecting rod 7546 to drive the push-pull rod 7542 to slide up and down. Subsequently, the piston 7543 slides up and down inside the cylinder 7541, causing the pressure inside the cylinder 7541 to periodically decrease and increase. When the pressure inside the cylinder 7541 decreases, the outlet pipe 753 draws coolant from the coolant reservoir 752 and introduces it into the cylinder 7541; when the pressure inside the cylinder 7541 increases, the delivery pipe 755 delivers coolant to the cylinder... The coolant inside the body 7541 is introduced into the cooling coil 751, and then returned to the coolant reservoir 752 through the return pipe 756. This cycle continues, with the coolant inside the cooling coil 751 circulating intermittently. The cooling coil 751 is in direct contact with the air inside the heat sink 71, allowing the coolant inside the cooling coil 751 to exchange heat with the hot air, thereby cooling the air. The intermittent circulation of the coolant not only prolongs the contact time between the coolant and the air per unit flow rate for sufficient cooling, but also the dynamic flow method can quickly remove heat, further improving cooling efficiency and thus achieving rapid heat dissipation for the electronic components inside the housing 1.
[0040] Please see Figure 1 and 9 The air guide assembly 76 includes an air outlet shroud 761 fixedly connected to the bottom of the heat sink 71. Several air guide plates 762 are rotatably connected to the inner side of the air outlet shroud 761. The air guide plates 762 are equidistantly distributed along the length of the air outlet shroud 761. Each air guide plate 762 is coaxially fixedly connected to a transmission gear 763. A guide rail 764 is fixedly connected to the outer wall of the heat sink 71. A movable frame 765 is slidably connected to the guide rail 764. An external rack 766 is fixedly connected to one end of the movable frame 765. The transmission gears 763 mesh with the external rack 766. The outer side of the heat sink 71 is provided with… The transmission component 767 includes two internal racks 7671 fixedly connected to the inner side of the movable frame 765. The two internal racks 7671 are symmetrically distributed along the center line of the movable frame 765. A rotating shaft 7672 is rotatably connected to the outer wall of the heat sink 71. A sector gear 7673 is fixedly connected to the bottom of the rotating shaft 7672. The sector gear 7673 alternately meshes with the two internal racks 7671. A third bevel gear 7674 is fixedly connected to the top of the rotating shaft 7672. A fourth bevel gear 7675 that meshes with the third bevel gear 7674 is fixedly connected to the output shaft of the motor 73.
[0041] Working principle: First, the starting motor 73 drives the drive spindle 745 to rotate, causing the air-cooled assembly 74, the liquid-cooled assembly 75, and the air-guiding assembly 76 to work simultaneously, wherein:
[0042] Working process of air-cooled component 74: The drive spindle 745 drives the second bevel gear 746 to rotate synchronously. Since the first bevel gear 744 and the second bevel gear 746 mesh and their gear ratio is 1:10, the first bevel gear 744 will accelerate and rotate, thereby causing the suction impeller 742 to rotate at high speed. This makes the air inlet at the top of the heat sink 71 in a negative pressure state, so that the hot air inside the housing 1 is drawn into the heat sink 71. This makes the ventilation hole 6 at the top of the housing 1 in a negative pressure state, thereby forcibly drawing the air outside the housing 1 into the housing 1, which can greatly enhance the ventilation effect inside the housing 1.
[0043] The working process of the liquid cooling assembly 75 is as follows: The drive spindle 745 drives the eccentric wheel 7547 to rotate synchronously, causing the connecting rod 7546 to drive the push-pull rod 7542 to slide up and down reciprocally. Subsequently, the piston 7543 slides up and down reciprocally inside the cylinder 7541, causing the pressure inside the cylinder 7541 to periodically decrease and increase. When the pressure inside the cylinder 7541 decreases, the liquid outlet pipe 753 draws the coolant from the coolant reservoir 752 and introduces it into the cylinder 7541; when the pressure inside the cylinder 7541 increases, the liquid delivery pipe 755 delivers the coolant from the cylinder 7541. The coolant is introduced into the cooling coil 751 and then returned to the coolant reservoir 752 through the return pipe 756. This cycle continues, with the coolant inside the cooling coil 751 circulating intermittently. The cooling coil 751 is in direct contact with the air inside the radiator 71, allowing the coolant in the cooling coil 751 to exchange heat with the hot air, thereby cooling the air. The intermittent circulation of the coolant not only prolongs the contact time between the coolant and the air per unit flow rate for sufficient cooling, but also the dynamic flow method can quickly remove heat, further improving cooling efficiency.
[0044] The working process of the air guide assembly 76: After cooling, the air is discharged through the air outlet 761. When the motor 73 starts, the fourth bevel gear 7675 rotates synchronously, causing the third bevel gear 7674 to drive the rotating shaft 7672 to rotate. At the same time, the sector gear 7673 rotates synchronously with the rotating shaft 7672. Since the sector gear 7673 alternately meshes with the two internal racks 7671, the two internal racks 7671 drive the movable frame 765 to slide in different directions, which causes the movable frame 765 to slide back and forth on the guide rail 764, causing the external rack 766 to reciprocate. This movement causes all the transmission gears 763 to rotate synchronously and all the air guide plates 762 to swing back and forth, so that the cold air inside the heat sink 71 is blown evenly into the housing 1. This allows the cold air to spread quickly and cool the area where the electronic components are located inside the housing 1, thereby achieving rapid heat dissipation of the electronic components. The entire structure, together with the air cooling component 74, can continuously draw in the air inside the housing 1, cool it with the liquid cooling component 75, and exhaust it with the air guide component 76 to achieve air circulation cooling, which greatly improves the heat dissipation effect of the embedded temperature controller and solves the defects of insufficient traditional heat dissipation.
[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
