Abstract
Description
Technical Field
[0001] The utility model relates to the field of passive filters, in particular to a high-efficiency heat dissipation passive filter device. Background Art
[0002] Passive filters, also known as LC filters, are filter circuits designed using a combination of inductors, capacitors, and resistors. They can filter out one or more harmonics. The most common and easily adopted passive filter structure is to connect the inductor and capacitor in series, which can form a low-impedance bypass for the main harmonics. Single-tuned filters, double-tuned filters, and high-pass filters are all passive filters.
[0003] After searching, a utility model high-efficiency heat dissipation passive filtering device with a publication number of CN207853470U is found, which includes a filter, a water inlet pipe and a water outlet pipe. The filter is provided with a water inlet pipe and a water outlet pipe on the outside, and the water inlet pipe and the water outlet pipe are detachably connected to the filter through a connecting seat. A cover plate is provided on the top of the filter, and a magnet is provided on the outside of the cover plate, and the magnet is fixedly connected to the cover plate by inlaying. A filter plate, a spring, a fixing seat, a slide plate and a water storage frame are provided inside the filter. The spring and the fixing seat inside the filter are axially symmetrically distributed, a filter plate is provided between the fixing seats, and a water storage frame is provided below the filter plate. This high-efficiency heat dissipation passive filtering device uses water cooling to cool the filter plate inside the filter. Cold water enters the water storage frame through the water inlet pipe, absorbs the heat generated by the filter plate and then flows out through the water outlet pipe to cool the filter plate, thereby increasing the service life of the filter plate.
[0004] The existing passive filtering device in the above patent is usually equipped with a cooling fan inside the shell to achieve the purpose of dissipating heat for the electronic components inside the passive filtering device. However, when the filtering device works for a long time, a large amount of heat will be generated inside. Simply relying on the fan for heat dissipation cannot achieve efficient and rapid heat dissipation. The above comparative case uses water cooling to cool the filter board, thereby increasing the service life of the filter board. However, the patent has a small heat dissipation area through the water cooling effect, and heat dissipation by water cooling alone is prone to insufficient heat dissipation.
[0005] Therefore, it is necessary to invent a high-efficiency heat dissipation passive filtering device to solve the above problems. Utility Model Content
