Description

Technical Field

[0001] The invention relates to a transformer, in particular to an electronic transformer with high-efficiency heat dissipation. Background Art

[0002] During the use of an electronic transformer, the coil winding and the internal magnetic core of the electronic transformer will generate heat due to eddy current and hysteresis loss. When the power of the electrical appliance connected to the electronic transformer changes, the current of the coil winding will change, causing the coil winding to heat up. The coil winding is arranged in a spiral stack inside the electronic transformer, and the heat inside it is difficult to dissipate to the outside, resulting in internal heat accumulation and difficulty in discharge. In addition, the magnetic core of the electronic transformer is also inside the skeleton of the electronic transformer, and the heat of the magnetic core is also in the internal space. The generated heat is still difficult to conduct from the inside to the outside. Long-term use will lead to transformer failure.

[0003] At present, most electronic transformers use external heat dissipation, that is, a cooling fan is directly installed on the outside of the electronic transformer, so that the cooling fan can carry away the heat dissipated to the surface of the electronic transformer through airflow. However, this method can only conduct the heat dissipated to the outside of the electronic transformer, that is, to dissipate heat from the outside of the electronic transformer. If the transformer needs to be kept at a suitable operating temperature, the cooling fan needs to be kept on during the use of the electrical appliance, resulting in increased power consumption for heat dissipation. In addition, in the current electronic transformer heat dissipation process, the power change of the electrical appliance connected to the electronic transformer causes the temperature change. For example, when the temperature of the electronic transformer rises, it is difficult to quickly and timely dissipate the heat inside the electronic transformer by using a traditional external fan, which causes damage to the electronic transformer and hidden dangers.

[0004] Therefore, it is necessary to develop an electronic transformer with high heat dissipation efficiency to solve the above problems. Summary of the Invention

[0037] Example 1, as Figures 1-12As shown, an electronic transformer with high efficiency in heat dissipation includes a middle ring 1, an end plate 2, a mounting plate 3, an interconnection frame 4, a connecting ring 5, a fixing plate 6, an outer cover 7, a terminal frame 8, a winding layer 9, a magnetic input device 10, an air guide device 11, an air supply device 12 and a heat dissipation device 13. The middle ring 1 is a ring-shaped pipe structure. The inside of the middle ring 1 is used to place the magnetic core of the transformer, and the outside of the middle ring 1 is used to wind the coil of the transformer. The wall of the middle ring 1 is a structure with multiple groups of vertical heat dissipation holes. The heat dissipation hole structure in the wall of the middle ring 1 is used to conduct heat dissipation between the magnetic core and the coil of the transformer. The outer layers of the upper and lower sides of the middle ring 1 are fixedly connected with end plates 2. The middle part of the end plate 2 is a ring structure, and the left and right sides of the end plate 2 are both structures with multiple groups of ventilation holes. The left and right sides of the two groups of end plates 2 are fixedly connected with mounting plates 3, and the opposite sides of the two groups of mounting plates 3 are fixedly connected with interconnection frames 4. The interconnection frames 4 are structures with open upper and lower sides. The middle part of the interconnection frames 4 is fixedly connected with connecting rings 5. The connecting rings 5 ​​are structures with air holes on the front and back sides. The air hole structure of the upper connecting ring 5 is used for air intake, and the air hole structure of the lower connecting ring 5 is used for exhaust. The opposite sides of the connecting rings 5 ​​can be detachably installed with fixing plates 6, and the fixing plates 6 block the space on the opposite side of the connecting rings 5. The front and rear positions between the two groups of mounting plates 3 are fixedly connected with outer covers 7, and the two groups of outer covers 7 are closed to close the space between the mounting plates 3. The upper and lower positions on the right side of the outer cover 7 are fixedly connected with wiring frames 8, and the wiring frames 8 are located inside the outer cover 7. The enclosed space is a structure with multiple copper joints. The wiring frame 8 is located outside the outer cover 7 along the wall. The inner and outer copper joint structures of the wiring frame 8 are electrically connected. The outer layer of the middle ring 1 is spirally wound with a winding layer 9. The winding layer 9 is a flat coil structure. The flat coil of the winding layer 9 is used to maintain the fit of its upper and lower positions. The fixed plate 6 is provided with a magnetic device 10 on the opposite side. The magnetic device 10 is used for detachable installation in the middle ring 1. The magnetic device 10 is placed in the middle ring 1 as the magnetic core of the transformer. The end plate 2 is provided with an air guide 11 on the opposite side. The air guide 11 is interconnected with the air vent structures on the left and right sides of the adjacent end plate 2, and the air guide 11 is connected to the vertical heat dissipation holes of the middle ring 1. The upper air guide device 11 is connected and interconnected, and is used to input cooling gas. The lower air guide device 11 is used to discharge the gas with heat after heat dissipation. An air supply device 12 is provided at the lower side of the upper fixing plate 6. The air supply device 12 absorbs air through the air hole structure on the front and rear sides of the upper connecting ring 5. The air supply device 12 is used to supply air to the upper connecting ring 5 and the upper end plate 2 to dissipate heat for the magnetic device 10 installed in the middle ring 1. The front and rear positions between the end plates 2 on the left and right sides are both provided with heat dissipation devices 13. The heat dissipation device 13 is used to separate the layers of the winding layer 9 so that there is a ventilation gap between the layers of the winding layer 9. The gap between the layers of the winding layer 9 corresponds to the position of the ventilation hole structure on the left and right sides of the end plate 2.The upper air guide device 11 inputs cooling gas into the gaps between the winding layers 9 through the vent structure of the upper end plate 2 to conduct the heat generated by the winding layer 9. The hot gas will be discharged from the vent structure of the lower end plate 2 into the lower air guide device 11, and then discharged from the lower air guide device 11 through the vent structure of the lower connecting ring 5. The air flow supplied by the air supply device 12 to the end plate 2 will also dissipate heat to the heat dissipation device 13. When the transformer is subjected to normal heat dissipation, the air supply device 12 can be turned on, and the air supply device 11 can be turned on. 2 The inhaled gas is blown into the upper connecting ring 5, and the gas will dissipate heat to the upper surface of the upper magnetic device 10. Then the gas will flow from the front and rear positions of the interconnection frame 4 into the space inside the outer cover 7. After the airflow flows out from the interconnection frame 4, it will dissipate heat to the heat dissipation device 13, and the heat dissipation device 13 will transfer the heat between the gaps between the layers of the winding layer 9 to the flowing gas, thereby driving the heat between the gaps between the layers of the winding layer 9. The gas will then flow from the lower side of the heat dissipation device 13 to the lower end plate 2, and the gas will pass through the lower magnetic device 10 and dissipate heat for it, and finally, the gas will be discharged from the lower connecting ring 5; when it is necessary to dissipate heat quickly for the transformer, or when the electrical appliances connected to the transformer are in a high-power working state, when it is necessary to quickly and directly discharge heat from the inside of the transformer, the air guide device 11 can be opened, and the upper air guide device 11 will inhale cooling gas from the outside and input it into the vent structure of the upper end plate 2. The cooling gas will enter the gaps between the winding layers 9 from the vent structure of the upper end plate 2, thereby quickly and over a large area taking away the winding heat. The heat generated between the layers 9 is discharged from the vent structure of the lower end plate 2 into the lower air guide 11. The air drawn into the upper air guide 11 also enters the vertical heat dissipation holes of the middle ring 1, thereby quickly conducting the heat generated between the winding layers 9 and the magnetic input device 10 installed on both sides of the middle ring 1. The heat-containing gas will enter the lower air guide 11, and the heat-containing gas in the lower air guide 11 will be discharged from the lower connecting ring 5, thereby completing the internal heat dissipation of the transformer.

[0038] like Figure 3 and Figure 14As shown, the magnetic input device 10 includes a connecting frame 101, a supporting frame 102 and a magnetic core 103. The connecting frames 101 are fixedly connected to the opposite sides of the fixing plates 6, and the connecting frames 101 are all vertical frame structures. The opposite sides of the connecting frames 101 are fixedly connected to the supporting frames 102, and the supporting frames 102 are all vertical frame structures. The opposite sides of the supporting frames 102 are fixedly connected to the magnetic core 103. The magnetic core 103 can be docked in the middle to form the magnetic core of the overall transformer; the fixing plate 6 can be removed at the connecting ring 5, and the fixing plate 6 can be withdrawn upward or downward from the connecting ring 5, so that the fixing plate 6 drives the air supply device 12, the connecting frame 101, the supporting frame 102 and the magnetic core 103 to move upward or downward, so that the magnetic core 103 is withdrawn from the middle ring 1; and when the magnetic core 103 is installed in the middle ring 1, the magnetic core 103 can be placed from the connecting ring 5 into the middle ring 1, so that the fixing plate 6 is reinstalled at the connecting ring 5.

[0039] like Figure 3 、 Figure 12 、 Figure 13 and Figure 17As shown, the air guide device 11 includes an air guide cabin 111, an interconnecting pipe 112, an air connecting pipe 113 and an air pump 114. The air guide cabins 111 are respectively fixedly connected to the left and right sides of the opposite side of the end plate 2. The air guide cabins 111 are structures with vents on both sides facing each other. The vent structure of the air guide cabin 111 is interconnected with the vent structure of the adjacent end plate 2. The two air guide cabins 111 installed on each end plate 2 are fixedly connected with an interconnecting pipe 112. The two interconnecting pipes 112 on the lower side are centrally open structures. The central open structure of the lower interconnecting pipe 112 is used for exhaust. The interconnecting pipe 112 is interconnected with the two connected air guide cabins 111. The air guide cabins 111 are fixed An air receiving pipe 113 is connected, and the air receiving pipe 113 is communicated with the adjacent air guide cabin 111 respectively. The air receiving pipe 113 is connected to the vertical heat dissipation holes at the adjacent positions of the middle ring 1 and is communicated with each other. An air pump 114 is installed on the right side of the air guide cabin 111 on the upper right side. The air outlet end of the air pump 114 is connected and communicated with the air guide cabin 111 on the upper right side. The air inlet of the air pump 114 is a structure with a filter. After the air pump 114 is started, it will suck cooling dust-free gas from its air inlet with a filter structure into the upper right air guide cabin 111, and transmit it to the upper left air guide cabin 111 through the upper interconnecting pipe 112, and the cooling air entering the upper air guide cabin 111 The body will enter the vent structure of the upper end plate 2 from its vent structure, and then enter the gaps between the layers of the winding layer 9, so that the cooling gas that enters will take away the heat in the gaps between the layers of the winding layer 9, and the gas will then be discharged from the vent structure of the lower end plate 2 and the vents of the lower air guide cabin 111. The discharged gas will enter the lower air guide cabin 111 and be discharged from the interconnecting pipe 112 with an open structure connected to the lower air guide cabin 111, and finally be discharged from the lower connecting ring 5. The cooling gas that enters the upper air guide cabin 111 will also enter the upper air connecting pipe 113. The cooling gas that enters the upper air connecting pipe 113 will pass through Through the vertical heat dissipation hole structure of the middle ring 1, the cooling gas entering takes away the heat between the magnetic core 103 installed on both sides of the middle ring 1 and the winding layer 9, and the gas containing heat will be discharged from the lower air pipe 113 into the lower interconnection pipe 112, and then discharged from the open structure of the lower interconnection pipe 112; in this way, turning on the air pump 114 can quickly extract the heat between the layers of the winding layer 9, and at the same time, it can also quickly extract the heat in the wall of the middle ring 1 through the air pipe 113. In this way, direct heat conduction can be carried out to the interior of the transformer. Compared with the traditional surface heat dissipation method, the internal direct heat conduction method can achieve fast and efficient heat dissipation.

[0040] like Figure 14As shown, the air supply device 12 includes an annular frame 121 and a fan 122. The annular frame 121 is fixedly connected to the lower side of the upper fixing plate 6. The annular frame 121 is a side hollow structure. The fan 122 is installed in the annular frame 121. The fan 122 is a downward-discharging brushless motor structure. When the fan 122 is started, the fan 122 will inhale gas from the hollow annular frame 121 and the pore structure of the upper connecting ring 5 and output it downward. The output gas will enter the upper connecting ring 5 and the upper connecting ring 5. At the side end plate 2, the gas is used to dissipate heat on the surface of the upper magnetic core 103. After passing through the upper magnetic core 103, the gas will be discharged to the front and rear sides along the position between the upper interconnecting frame 4, and then the gas will enter the position inside the outer cover 7. The gas will then dissipate heat to the upper heat dissipation device 13 and spread to the space inside the outer cover 7. The gas in the lower layer of the outer cover 7 will flow to dissipate heat to the lower heat dissipation device 13, and then dissipate heat to the lower surface of the magnetic core 103, and finally be discharged from the lower connecting ring 5.

[0041] like Figure 11 、 Figure 12 、 Figure 15 and Figure 16As shown, the heat dissipation device 13 includes a guide frame 131, a first heat dissipation row 132, a heat conducting plate 133 and a heat conducting frame 134. The guide frames 131 are respectively fixedly connected to the front and rear positions of the inner wall of the opposite sides of the end plate 2. A first heat dissipation row 132 is slidably placed between the two guide frames 131 corresponding to each left and right position. The first heat dissipation row 132 is air-cooled. The opposite side surfaces of the first heat dissipation row 132 are made of copper. A heat conducting plate 133 is provided between the two groups of first heat dissipation rows 132 corresponding to each upper and lower position. The two groups of heat conducting plates 133 corresponding to each upper and lower position are provided between the two groups of first heat dissipation rows 132. 33 are fixedly connected with a heat conducting frame 134, and each two groups of two groups of heat conducting sheets 133 corresponding to the upper and lower positions and a group of heat conducting frames 134 constitute a heat conducting combination. The heat conducting sheets 133 are made of copper, and the heat conducting sheets 133 are respectively in contact with the copper material structure of the adjacent first heat sink 132. The heat conducting frames 134 are made of insulating heat conductive plastic material. After each layer of winding layer 9 is wound to the middle ring 1, a group of heat conducting combinations consisting of heat conducting sheets 133 and heat conducting frames 134 are respectively inserted into the position between the two groups of end plates 2, and then the next layer of winding layer 9 is wound, and then Insert a set of heat-conducting combinations. Such installation can form gaps between the winding layers 9, and each layer of the winding layer 9 will also be in contact with the heat-conducting frame 134. After winding the winding layer 9, the first heat sink 132 is finally installed between the two guide frames 131 corresponding to each left and right position, so that the copper material structure of the first heat sink 132 is in contact with the adjacent heat-conducting sheet 133 respectively; and the gas input from the fan 122 will be blown into the position between the front and rear positions after passing through the upper magnetic core 103. At this time, the input gas will pass through the two first heat sinks on the upper side. The gas then enters the outer cover 7 and passes through the two first heat sinks 132 on the lower side, and the passing gas takes away the heat of the first heat sinks 132; the contact between the first heat sinks 132 and the heat conducting sheets 133, as well as the contact between the heat conducting sheets 133 and the heat conducting racks 134, will make the heat between the layers of the winding layer 9 be conducted to the heat conducting racks 134 in contact therewith in a contact manner, and the heat conducting racks 134 will conduct the heat to the heat conducting sheets 133, so that the heat conducting sheets 133 will conduct the heat to the first heat sinks 132 for heat dissipation by conduction through the passing airflow.

[0042] Example 2, as Figure 18 and Figure 19As shown, it also includes a heat insulation device 14, which includes a vacuum layer 141 and a spiral air duct 142. The heat insulation device 14 is arranged on the inner layer of the outer cover 7. The heat insulation device 14 is used to isolate the internal space of the outer cover 7 from the heat exchange outside, and prevent the heat dissipated by other electronic components in the outside world and the heat derived from being re-transmitted to the inside of the outer cover 7. The inner layer of the outer cover 7 is fixedly connected with a vacuum layer 141, and the vacuum layer 141 is used to isolate the heat exchange between the outer cover 7 and the outside world in a vacuum manner. The inner layer of the vacuum layer 141 is fixedly connected with a spiral air duct 142, and the spiral air duct 142 is used to spirally guide the gas passing through the first heat dissipating row 132 on the upper side, so that the gas flows downward in a spiral manner, so that the spirally flowing gas contacts the winding layer 9 over a larger area, further conducts the heat of the winding layer 9, further improves the heat dissipation efficiency, and reduces the energy consumption required for heat dissipation.

[0043] like Figure 13 As shown, a cooling row 15 is also included. The cooling row 15 is fixedly connected to the air guide cabin 111 at the upper right position. The cooling row 15 is a diode cooling plate. After the cooling row 15 is started, the gas input from the air pump 114 will pass through the cooling row 15 for further cooling, so that the cooled gas can more effectively dissipate heat to the gaps between the winding layers 9 and the inner wall of the middle ring 1.

[0044] like Figure 14 As shown, second heat sinks 16 are also included. The second heat sinks 16 are fixedly connected to the opposite sides of the magnetic cores 103. The opposite sides of the second heat sinks 16 are made of copper. The copper structures of the second heat sinks 16 are respectively connected to the end faces of the adjacent magnetic cores 103. The airflow input into the connecting ring 5 by the fan 122 will pass through the second heat sinks 16, so that the second heat sinks 16 can dissipate heat for the magnetic cores 103 more efficiently and quickly.

[0045] Example 3, as Figures 1-19As shown, the production and assembly method of the electronic transformer with high-efficiency heat dissipation is as follows: a flat-structured insulated copper coil is installed on the winding machine; the assembly combination of the middle ring 1 and the end plate 2 is placed on the winding machine, and the outer layer of the middle ring 1 is wound with an insulated copper coil to form a winding layer 9, and the two ends of the insulated copper coil are reserved for connection to the copper joints on the left side of the wiring frame 8. This first winding layer 9 is the main coil of the transformer and its adapted electrical appliance, and then a group of heat-conducting combinations consisting of a heat-conducting sheet 133 and a heat-conducting frame 134 is inserted, so that the heat-conducting frame 134 of the heat-conducting combination is in contact with the outermost coil of the winding layer 9; then, the outer layer where the first winding layer 9 and the heat-conducting combination are assembled on the outside of the middle ring 1 is wound with an insulated copper coil by the winding machine to form a second winding layer 9, and the two ends of the insulated copper coil are reserved for connection to the copper joints on the left side of the wiring frame 8, and then the next group of heat-conducting combinations are installed according to the above steps, thus forming multiple layers of winding layers 9 and multiple layers of heat-conducting combinations. The heat conducting combination consisting of the heat conducting sheet 133 and the heat conducting frame 134 creates gaps between each layer of the winding layer 9. After the winding layer 9 is wound, the first heat sink 132 is finally installed between the two guide frames 131 corresponding to each left and right position, so that the copper material structure of the first heat sink 132 contacts the adjacent heat conducting sheet 133. In this way, the winding layer 9 and the heat conducting combination consisting of the heat conducting sheet 133 and the heat conducting frame 134 are assembled. The assembled part is then installed on the mounting plate 3. The magnetic core 103 is then placed in the middle ring 1 through the fixing plate 6, and the fixing plate 6 is fixedly connected to the end of the connecting ring 5. The two outer covers 7 are then folded and fitted onto the outer layer of the middle ring 1 from the front and back positions, and the outer covers 7 are fixedly connected to the mounting plate 3. The two outer covers 7 surround the inner and outer spaces of the middle ring 1, isolating the magnetic core 103 and the winding layer 9 installed inside and outside the middle ring 1 from the outside world. The electronic transformer with high heat dissipation efficiency is then installed in the control chassis.
