Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter heat dissipation technology, and in particular to a heat dissipation device for filters. Background Technology
[0002] In this era of rapid development in modern electronic technology, filters, as a key electronic component, are widely used in numerous fields and play an indispensable role. In communication systems, filters are used to filter and separate signals of different frequencies, ensuring that signals of specific frequencies can be transmitted accurately and without error, avoiding mutual interference between signals, thereby guaranteeing the quality and stability of communication. For example, in mobile communication base stations, filters can accurately filter signals from various communication frequency bands, enabling different users to communicate simultaneously and efficiently.
[0003] During normal operation, filters generate a significant amount of heat due to the current flow and electromagnetic conversion within their internal electronic components. This heat must be dissipated promptly to prevent the internal temperature of the filter from rising continuously. Currently, most existing filters still rely primarily on natural heat exchange for cooling, utilizing heat conduction, convection, and radiation between the filter and its surroundings. However, this natural heat exchange method is relatively inefficient, especially in environments with relatively enclosed spaces and poor air circulation. Heat is difficult to remove quickly, and it accumulates over time, causing the internal temperature of the filter to rise continuously. This can accelerate the aging of electronic components, significantly shorten their lifespan, and may even lead to component damage and system malfunctions.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0035] In one embodiment of this utility model, such as Figure 1-5As shown, a heat dissipation device for a filter is provided, comprising a filter body 10 and a heat dissipation assembly. The heat dissipation assembly includes an outlet pipe 20, an inlet pipe 21, and a heat dissipation module 30. The outlet pipe 20 and the inlet pipe 21 are arranged side by side on one side of the filter body 10. The heat dissipation module 30 is located at the bottom of the filter body 10 and is connected to the outlet pipe 20 and the inlet pipe 21 respectively via a first connecting pipe 34.
[0036] By setting up heat dissipation components, a high-efficiency water cooling circulation system is constructed through the water outlet pipe 20, the water inlet pipe 21, and the heat dissipation module 30. The coolant enters the heat dissipation module 30 through the water inlet pipe 21, absorbs the heat generated by the filter, and then is discharged from the water outlet pipe 20, forming a continuous heat exchange process. The filter body 10 can dissipate heat without relying on the natural flow of air, which greatly improves the heat dissipation efficiency and avoids the accumulation of heat inside the filter.
[0037] Preferably, at least one set of filter bodies 10 is provided, and multiple sets of filter bodies 10 are arranged side by side on the outside of the water outlet pipe 20 or the water inlet pipe 21. At least one set of heat dissipation modules 30 is provided, and the number of heat dissipation modules 30 corresponds to the number of filter bodies 10. By providing multiple sets of filter bodies 10 and their corresponding heat dissipation modules 30, efficient heat dissipation can be achieved for multiple filters simultaneously, avoiding the problem of heat accumulation when multiple filters are working at the same time, effectively reducing the overall temperature of the filters, and ensuring the stable operation of each filter.
[0038] Preferably, the heat dissipation module 30 includes a first water-cooled plate 31, a heat-conducting component 32, and a fixing frame 33. The first water-cooled plate 31 is located at the bottom of the filter body 10 and is connected to the water outlet pipe 20 and the water inlet pipe 21 respectively through a first connecting pipe 34. One end of the heat-conducting component 32 is wrapped around the outside of the filter body 10, and the other end is fixedly located at the top of the first water-cooled plate 31. The fixing frame 33 is sleeved on the filter body 10 corresponding to the outside of the heat-conducting component 32, and multiple sets of locking members 36 for fixing the heat-conducting component 32 are provided between the fixing frame 33 and the heat-conducting component 32. The locking members 36 are locking screws. By setting a first water-cooled plate 31 and a heat-conducting component 32, and by having the first water-cooled plate 31 contact the bottom of the filter body 10 and the heat-conducting component 32 wrap around the outside of the filter body 10 and connect to the first water-cooled plate 31, heat can be absorbed from the bottom and sides of the filter body 10 in multiple dimensions. This enables more comprehensive and efficient collection of heat generated by the filter, reduces the residence time of heat inside the filter, effectively lowers the internal temperature of the filter, slows down the aging of electronic components, and avoids component damage and system failure. Simultaneously, the distance between the heat-conducting component 32 and the fixed frame 33 is adjusted by tightening the locking member 36, that is, the degree of contact between the heat-conducting component 32 and the filter body 10 is adjusted to ensure that the heat-conducting component 32 and the filter body 10 can fit tightly together. For example, if the locking member 36 on one side of the fixed frame 33 located on both sides of the filter body 10 is adjusted to a certain position, the locking member 36 on the other side is tightened, so that the locking member 36 on the opposite side presses its corresponding heat-conducting component 32 onto the filter body 10. The locking member 36 on that side continuously approaches and squeezes its corresponding heat-conducting component 32, so that the heat-conducting component 32 is pressed onto the filter body 10, thereby achieving mutual contact between the two sides of the filter body 10 and the corresponding heat-conducting component 32.
[0039] Specifically, the heat-conducting component 32 includes multiple sets of first heat-conducting blocks 321 and second heat-conducting blocks 322, which are made of heat-conducting materials, such as copper plates. The multiple sets of first heat-conducting blocks 321 are circumferentially disposed on the outside of the filter body 10 and abut against the filter body 10. The multiple sets of second heat-conducting blocks 322 are equally spaced on the first water-cooling plate 31 and abut against the first water-cooling plate 31. The first heat-conducting blocks 321 and the second heat-conducting blocks 322 are connected by heat-conducting pipes 323. By setting up a first heat-conducting block 321, a second heat-conducting block 322, and a heat-conducting pipe 323, the first heat-conducting block 321 and the second heat-conducting block 322 are connected by the heat-conducting pipe 323 to form a complete heat-conducting structure. This structure can more accurately capture the heat from different parts of the filter and quickly conduct it to the first water-cooling plate 31 through the heat-conducting pipe 323. This effectively transfers heat from inside the filter to the coolant, improves heat dissipation efficiency, avoids local heat accumulation inside the filter, ensures the normal working environment of the electronic components inside the filter, and extends the service life of the components.
[0040] Furthermore, a first thermally conductive pad 351 is provided between the first thermally conductive block 321 and the filter body 10. A second thermally conductive pad 352 is provided between the second thermally conductive block 322 and the first water-cooled plate 31. A third thermally conductive pad 353 is provided between the first water-cooled plate 31 and the filter body 10. In this embodiment, the first thermally conductive pad 351, the second thermally conductive pad 352, and the third thermally conductive pad 353 are all PAD thermally conductive sheets. The first thermally conductive pad 351, the second thermally conductive pad 352, and the third thermally conductive pad 353 respectively fill the gaps between the first thermally conductive block 321 and the filter body 10, between the second thermally conductive block 322 and the first water-cooled plate 31, and between the first water-cooled plate 31 and the filter body 10, so that heat can be transferred to the first water-cooled plate 31 in an alternating manner. This effectively transfers heat from inside the filter to the coolant, improves heat dissipation efficiency, avoids local heat accumulation inside the filter, ensures the normal working environment of the electronic components inside the filter, and extends the service life of the components.
[0041] Furthermore, the fixing frame 33 includes a first frame 331 and a second frame 332. The first frame 331 has outwardly extending first connecting ends at both ends, each with an outwardly protruding slot 331a. The second frame 332 has outwardly extending second connecting ends at both ends, each with an outwardly protruding locking block 332a, and the slot 331a and the locking block 332a are detachably connected. This detachable connection between the first frame 331 and the second frame 332 via the slot 331a and the locking block 332a facilitates the installation, removal, and maintenance of the filter body 10 and the heat dissipation module 30.
[0042] Furthermore, the second frame 332 is provided with multiple sets of clearance slots 332b for avoiding the wiring terminals in the filter body 10. By setting the clearance slots 332b, it is ensured that the normal wiring and use of the filter are not affected when the fixing frame 33 is installed.
[0043] Furthermore, the first water-cooled plate 31 is provided with a flow channel 311 for coolant flow, and both ends of the flow channel 311 are connected to the inlet pipe 21 and the outlet pipe 20 respectively through the first connecting pipe 34. Multiple sets of parallel protrusions 312 are provided on the sidewall of the flow channel 311. In this embodiment, the protrusions 312 are also provided with connecting holes for fixing the filter body 10.
[0044] By setting up a flow channel 311, and providing multiple sets of parallel protrusions 312 on the sidewall of the flow channel 311, the contact area between the coolant and the sidewall of the flow channel 311 is increased, the heat exchange efficiency is improved, the internal electronic components of the filter are ensured to operate at a suitable temperature, and the service life of the components is extended.
[0045] Furthermore, the inlet pipe 21 is provided with an inlet 211 for coolant to enter. The outlet pipe 20 is provided with an outlet 201 for coolant to exit. This facilitates the management of coolant addition and discharge, and makes it easier for maintenance personnel to operate and maintain the heat dissipation system.
[0046] Preferably, the heat dissipation component further includes a water-cooled fan 41 and a mounting bracket 42. The mounting bracket 42 is located on the same outer side as the outlet pipe 20 and the inlet pipe 21. The water-cooled fan 41 is mounted on the mounting bracket 42 and is connected to the inlet pipe 21 and the outlet pipe 20 respectively via a second connecting pipe 43. The water-cooled fan 41 has a second water-cooling plate 44, and the two ends of the second water-cooling plate 44 are respectively connected to the second connecting pipe 43. The second water-cooling plate 44 has multiple sets of water-cooling pipes 45 connected end to end. By setting up the water-cooled fan 41, the addition of the water-cooled fan 41 and the second water-cooling plate 44 further enhances the heat dissipation effect. When the filter is operating at high power, the water-cooled fan 41 can accelerate the heat dissipation of the coolant, allowing the coolant to cool down more quickly and re-enter the circulation system to absorb heat, effectively preventing heat from accumulating as the operating time increases, and ensuring the stable operation of the filter under various operating conditions.
[0047] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
