Description
Technical Field
[0001] The invention relates to the technical field of metallized film capacitors, and in particular to a high-performance metallized film capacitor and a manufacturing method thereof. Background Art
[0002] Metallized film capacitors are also called film capacitors. They use metallized film dielectrics. Film capacitors use metal foil as electrodes, which are overlapped with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate at both ends and then wound into a cylindrical capacitor.
[0003] Patent publication number CN112635197A discloses a metallized film capacitor with high efficiency heat dissipation, including a shell, a component is fixedly installed at the middle position of the bottom surface of the shell, a through groove is opened at the middle position of the surface of one side of the shell, a mounting plate is fixedly installed on the surface of one side of the through groove, and a driving motor is fixedly installed on the middle position of the surface of one side of the mounting plate. This metallized film capacitor with high efficiency heat dissipation drives the roller to rotate by starting the driving motor, and a plurality of fan blades are installed on one side of the roller to generate wind force, accelerate the air flow speed inside the shell, enter the shell from the through groove to dissipate the heat of its components, and then discharge the heat to the outside through a plurality of heat dissipation holes, and prevent the dust from entering the shell from the outside by setting a filter net, and the heat conduction plate is set to be used to export the heat inside the shell to prevent the heat from accumulating inside the shell, and the heat sink is set to dissipate the exported heat to the outside, which is convenient for heat conduction and heat dissipation, effectively improves people's use efficiency, enhances the practicality of the device, can efficiently dissipate the heat inside the capacitor, will not cause the internal circuit and components to short-circuit or damage, and effectively improves work efficiency.
[0004] However, although the above scheme can produce a certain heat dissipation effect on the inside of the capacitor when using a number of fan blades, a heat conducting plate and a heat sink to generate wind to dissipate heat inside the capacitor, the heat dissipation effect on the inside of the capacitor through the fan blades alone is very limited. When the metallized film capacitor is used for a long time, the temperature of the electrical components inside the capacitor will continue to rise, thereby causing the temperature inside the capacitor to rise. Since there is no cooling warning mechanism in the capacitor, it is impossible to timely reduce and warn the continuously rising temperature inside the capacitor. If the capacitor continues to work under high temperature conditions, it is very easy to cause damage to the electrical components. In severe cases, it may even cause the capacitor to explode due to the high temperature, affecting the use of the capacitor and causing safety hazards. Therefore, a high-performance metallized film capacitor and a manufacturing method thereof are proposed. Summary of the invention

[0054] Example 3
[0055] Based on Example 2, please refer to Figure 1-8 As shown, a method for manufacturing a high-performance metallized film capacitor includes the following steps:
[0056] Step 1: Install the air cooler 81 and the exhaust fan 85 on the top of the shell 1, and then install the first installation tube 82 and the second installation tube 84 at the bottom air outlets of the air cooler 81 and the exhaust fan 85 respectively, install the corrugated air guide plate 816 in the first installation tube 82, install the air outlet cover 819 on one side of the first installation tube 82 through the air guide pipe 818, install the air guide inclined plate 820 in the second installation tube 84, and install the filter plate 87 on one side of the second installation tube 84, install the air supply tube 83 between the first installation tube 82 and the second installation tube 84, and install the hair dryer 86 on one side of the second installation tube 84 through the air guide cover 821;
[0057] Step 2: The water tank 89 and the water pump 88 are fixedly installed on one side of the first installation tube 82, and the water supply pipe 810, the water return pipe 811 and the water inlet 812 are fixedly installed on the water tank 89. The water supply pipe 810 and the water return pipe 811 are fixedly connected to the water inlet and the water outlet of the water pump 88 respectively;
[0058] Step 5: The flashing light 10 and the alarm 11 are fixedly mounted on the top of the housing 1, and the temperature sensor 7 is fixedly mounted on the inner wall of the housing 1, and then the electrical components 4, the temperature sensor 7, the flashing light 10, the alarm 11, the cooling fan 12, the air cooler 81, the exhaust fan 85, the hair dryer 86, the water pump 88 and the semiconductor cooling sheet 813 are all electrically and linearly connected to the control machine 9;
[0059] Step 6. Fix the cooling fan 12 on one side of the shell 1, fix the fixing plate 61 with the fixing groove 62 on the movable door panel 2, fix the mounting plate 63 on one side of the shell 1, rotatably install the rotating rod 64 with the fixing block 65 on the mounting plate 63, and then movably install the movable door panel 2 on one side of the shell 1 through the hinge 3.
[0060] The working principle of the present invention is as follows: the temperature in the housing 1 is monitored in real time by the temperature sensor 7 and the temperature value is transmitted to the temperature control machine 9. When the temperature in the housing 1 reaches a certain value, the control machine 9 with the PLC controller starts the air cooler 81, the exhaust fan 85, the hair dryer 86, the water pump 88 and the semiconductor refrigeration sheet 813. The air cooler 81 blows cold air into the first installation cylinder 82. A part of the cold air enters the air guide 818 through the air outlet hole 817 on the corrugated air guide plate 816, and then blows the cold air onto the electrical component 4 through the air outlet cover 819, thereby cooling the electrical component 4. The other part of the cold air enters the air supply tube 83 through the corrugated air guide plate 816. When the cold air passes through the air supply tube 83, it exchanges heat with the electrical component 4 located above the air supply tube 83, and further cools the electrical component 4. The cold air in the air supply tube 83 enters the second installation tube 84 through the exhaust fan 85, and the excess cold air is discharged, so that the circulation of the cold air is realized. The cold air in the second installation tube 84 is blown into the housing 1 by the hair dryer 86 while blowing into the air guide cover 821. At the same time, the dust in the air blown by the hair dryer 86 is filtered through the filter plate 87.
[0061] At the same time, the semiconductor refrigeration sheet 813, the water pump 88 and the cooling fan 12 are started by the control machine 9, the water in the water tank 89 is cooled by the semiconductor refrigeration sheet 813, and the cold water in the water tank 89 is pumped into the water supply pipe 810 by the water pump 88. Heat exchange occurs between the cold water passing through the water supply pipe 810 and the first installation cylinder 82 and the corrugated air guide plate 816, and the temperature in the first installation cylinder 82 and the temperature of the corrugated air guide plate 816 are further reduced, so that the temperature of the cold air passing through the corrugated air guide plate 816 is lower, and then the water that has undergone heat exchange is re-delivered to the water tank 89 through the return pipe 811, which is conducive to the recycling of water;
[0062] If the temperature in the housing 1 continues to rise, when the temperature reaches a certain value, the flashing light 10 and the alarm 11 are started by the control machine 9, so that the flashing light 10 flashes and the alarm 11 sounds an alarm;
[0063] It should be noted that the temperature value here is set in advance by the administrator and input into the control machine 9 with a PLC controller, and the next operation is determined and operated by the PLC controller, and the PLC technology is an existing and mature technology, so it will not be described in detail here;
[0064] When the movable door panel 2 needs to be opened to inspect the inside of the housing 1, the fixing block 65 is rotated to a certain position, and then the movable door panel 2 is pulled to rotate outward to make the fixing block 65 away from the fixing groove 62 to release the position lock of the movable door panel 2.
[0065] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
