[0002] Horn capacitors are a type of capacitor. Horn capacitors are typically used in high voltage, high current, and high frequency applications, such as RF (wireless communication) circuits, high power power supply circuits, antenna matching networks, and radar systems.

[0003] When in use, ultra-high voltage bullhorn capacitors generate much more heat than other capacitors due to their large capacity and high voltage resistance. However, existing ultra-high voltage bullhorn capacitors are rarely equipped with corresponding heat dissipation structures, which makes it difficult to assist the capacitor in heat dissipation and the heat is difficult to discharge, which may affect the stability and safety of the capacitor.

[0004] To this end, we propose an ultra-high voltage horn capacitor with built-in heat dissipation to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0020] Reference Figure 1-3A self-heating ultra-high voltage horn capacitor comprises a core package 1, two pins 2 are fixedly connected to the bottom of the core package 1, a heat dissipation shell 3 is covered on the side and top of the core package 1, a plurality of heat dissipation fins 4 are vertically fixedly connected to the top of the heat dissipation shell 3, a shell 5 opened up and down is arranged outside the heat dissipation shell 3, and a plurality of connecting pieces 6 are fixedly connected between the shell 5 and the heat dissipation shell 3, the heat dissipation shell 3, the heat dissipation fins 4 and the connecting pieces 6 are all made of aluminum alloy, because aluminum alloy is light and has high heat conduction efficiency, and is cheaper than copper, so aluminum alloy is selected, the top of the shell 5 is detachably connected to a top shell 7 opened at the bottom, a plurality of ventilation slots 8 are arranged on the top of the top shell 7, and the top shell 7 is provided with a plurality of ventilation slots 8. A fan 9 is fixedly connected at the center of the top wall, and an air duct is formed through the gap between the outer shell 5 and the heat dissipation shell 3. The air enters the air duct from the ventilation slots 8 through the fan 9. In conjunction with the staggered heat dissipation fins 4 and connecting pieces 6, the circulating air cools the heat dissipation shell 3, thereby achieving heat discharge from the core package 1. A heat dissipation pipe 10 is wound around the outside of the heat dissipation shell 3, and both ends of the heat dissipation pipe 10 pass through the outer shell 5 and are commonly connected to a heat dissipation component. The wound heat dissipation pipe 10 can increase its contact area with the heat dissipation shell 3, thereby improving the heat dissipation capacity of the heat dissipation shell 3. A temperature detector can be provided on the outside of the heat dissipation shell 3 to determine whether the temperature requires the heat dissipation component to be turned on.

[0021] Reference Figure 1-3 The heat sink 4 and the connecting sheet 6 are arranged in a staggered manner. The staggered arrangement can increase the number of heat sinks 4 as much as possible without affecting the air discharge, thereby improving the heat dissipation capacity. The thickness of the heat sink 4 and the connecting sheet 6 is less than 5 mm, thereby increasing the contact area between the air and the heat sink 4 and the connecting sheet 6, and further improving the heat dissipation capacity.

[0022] A connecting tube 11 is fixedly connected to the outer side of the top of the outer shell 5. The inside of the connecting tube 11 and the bottom of the outer side of the top shell 7 are provided with threads. The top shell 7 is threadedly connected to the upper end of the connecting tube 11, thereby realizing a detachable connection between the outer shell 5 and the top shell 7.

[0023] The outer top wall of the top shell 7 is magnetically connected to a filter 12 for filtering air, so as to filter out impurities in the air and prevent the impurities from entering the top shell 7 and affecting the normal operation of the fan 9 and the air duct. The fan 9 blows air downward. Compared with sucking air, blowing air can make the air flow faster and improve the heat dissipation capacity.

[0024] A bottom cover 13 is fixedly connected to the bottom end of the heat dissipation shell 3, and the top surface of the bottom cover 13 is in contact with the bottom surface of the core package 1. The bottom cover 13 is provided with a through hole for the pin 2 to pass through, thereby achieving full coverage of the core package 1. The heat conduction between the bottom cover 13 and the heat dissipation shell 3 can prevent the bottom surface temperature of the core package 1 from being too high.

[0025] Reference Figure 4The heat dissipation component includes a water tank 14 fixedly connected to both ends of the heat dissipation pipe 10. The water tank 14 is connected to the heat dissipation pipe 10 and is filled with heat dissipation liquid. A water pump 15 is fixedly installed in the water tank 14. The heat dissipation liquid brings the heat in the heat dissipation pipe 10 to the water tank 14, further improving the heat dissipation capacity.

[0026] Working principle:

[0027] When using the ultra-high voltage horn capacitor with self-heating, the thread of the top shell 7 is rotated into the connecting tube 11, and the fan 9 is turned on. The fan 9 rotates and sends wind from the ventilation slot 8 into the gap between the heat dissipation shell 3 and the outer shell 5. The air flows through the heat sink 4 and the connecting plate 6 and takes away the heat of the heat dissipation shell 3, and reduces the temperature of the core package 1. When the air cooling cannot control the temperature of the capacitor and the temperature of the heat dissipation shell 3 is too high, the water pump 15 can be turned on, and the heat dissipation liquid flows between the water tank 14 and the heat dissipation tube 10 until the heat dissipation liquid reduces the temperature of the heat dissipation shell 3 to the required temperature.

[0028] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
