Description

Technical Field

[0001] The utility model relates to the technical field of filter heat dissipation, and in particular to a heat dissipation device for a multilayer filter. Background Art

[0002] A filter is a device used for signal processing. Its main function is to remove specific frequency components in the signal to improve the quality of the signal or extract useful information. It is composed of components such as resistors, capacitors and inductors. The heating of the filter is mainly caused by the power consumption generated by the internal components of the filter. A multilayer filter is a filter structure composed of multiple filters in cascade or parallel connection. This structure can combine the characteristics of multiple filters to improve the performance of the filter. The filter can be an integrated structure or a multilayer filter with multiple filters connected together. There are connection gaps between the multilayer structures. When the filter is working, the components will generate heat, which will cause the temperature of the filter to rise. If the heat generated by the filter is too high, it may cause the filter performance to decline, the stability to decrease, or even damage.

[0003] The patent name that has been published is a Chinese utility model patent with the publication number CN215070353U, which includes a shell, a filter body, a heat dissipation component and a cooling mechanism. The heat dissipation component is located inside the filter body, and the cooling mechanism is located on the side of the filter body. The filter body and the cooling mechanism are both installed on the inside of the shell. The heat inside the filter can be discharged through the heat dissipation component. At the same time, the cooling mechanism can quickly reduce the temperature of the filter, solving the problem that the heat generated by the filter during operation is difficult to discharge, causing the temperature to rise and affect its operation. However, the heat accumulation phenomenon at the connection gap of the multi-layer filter cannot be handled. Utility Model Content

[0021] Example

[0022] Please refer to Figure 1-Figure 5 The utility model provides a heat dissipation device for a multi-layer filter, comprising a multi-layer filter 1, a supporting shell 2, a cooling component, and a speed-increasing pipeline 6.

[0023] Furthermore, the multilayer filter 1 may be an integrated multilayer filter that realizes multiple filtering functions, or a multilayer filter in which multiple filters are connected together, and there are connection gaps between the filters of the multilayer structure.

[0024] In the prior art, a multilayer filter 1 includes a filter body and ear plates for installation arranged at the front and rear ends of the filter body.

[0025] In this embodiment, the support shell 2 is a cover-type structure, the space inside of which can completely cover the filter body of the multilayer filter 1 and is located above the ear plate, and there is extra space in the support shell 2 for air flow, and the front and rear end surfaces of the support shell 2 are provided with a cooling component. In this embodiment, the cooling component is preferably a fan, and the cooling component blows air into the support shell 2 from the front end surface of the support shell 2. A speed-increasing pipe 6 is provided between the front end of the support shell 2 and the cooling component. The speed-increasing pipe 6 is in the shape of a conical channel, and the minimum diameter of the conical channel faces the inside of the support shell 2 and is close to the side of the multilayer filter 1, and the maximum diameter of the conical channel faces the cooling component. A plurality of speed-increasing pipes 6 are evenly fixedly arranged on a fixing plate 601, and the fixing plate 601 is fixedly mounted on the front inner wall of the support shell 2. The fixing plate 601 intercepts the wind, and forces the cooling component to blow air through the speed-increasing pipe and then blow it toward the multilayer filter 1.

[0026] Specifically, when the working multilayer filter is dissipating heat, the cooling component inhales cold air from the front end of the supporting shell 2, and the cold air passes through the larger channel opening of the speed-increasing pipe 6, and enters the supporting shell 2 from the smaller diameter opening of the conical channel of the speed-increasing pipe 6, blowing and cooling the multilayer filter 1 in the supporting shell 2. In this process, the air intake of the cooling component remains unchanged, but the diameter of the channel for the air flow becomes smaller, so the air flow rate becomes faster accordingly, and the wind speed of the cold air blown out from the speed-increasing pipe 6 to the multilayer filter 1 increases, and the cooling effect is more obvious.

[0027] Specifically, if the multilayer filter 1 is a multilayer filter in which multiple filters are connected together, the heat accumulation phenomenon in the connecting gaps between the filters will be more obvious. If a low-speed wind volume blows through this type of filter, the cold air cannot flow into the connecting gaps for heat dissipation. The structure of the speed-increasing duct 6 is used to increase the incoming wind speed, so that the cold air can enter the deeper filter gap connection and take away the heat for heat dissipation.

[0028] In some embodiments, a heat dissipation device for a multi-layer filter further includes a limiting plate 5 and a mounting plate 201 provided at the bottom of the front and rear ends of the supporting shell 2 .

[0029] Furthermore, the mounting plate 201 is fixedly arranged at the bottom of the front and rear outer walls of the supporting shell 2, and a long waist groove is arranged on the mounting plate 201. The front and rear ends of the multilayer filter 1 are generally provided with ear plates for installation, and the waist groove will overlap with the mounting holes of the ear plates of the multilayer filter 1. The long waist groove can overlap with the ear plates at different positions of the multilayer filter 1. When installing the heat dissipation device on the multilayer filter 1, the mounting screws of the multilayer filter 1 can be directly loosened to fix the heat dissipation device and the multilayer filter 1 together.

[0030] Furthermore, two relatively arranged limit plates 5 are fixedly mounted on the front and rear end surfaces of the support shell 2, and the limit plates 5 are L-shaped, so that the front and rear end surfaces of the support shell 2 form a sliding groove for quick-detachable installation of the cooling component. The cooling component can slide up and down in the sliding groove, which is convenient for manual quick removal and replacement.

[0031] Of course, the outer walls of the front and rear end surfaces of the supporting shell 2 are provided with openings corresponding to the cooling components, so that the air blown by the cooling components enters the supporting shell 2 through the openings.

[0032] Specifically, since the cooling component contains electronically controlled components, it is easy to produce working losses. Therefore, the cooling component can be quickly removed and the components can be replaced through the quick replacement of the limit plate 5, without the need to disassemble the entire heat dissipation device, thereby avoiding affecting the operation of the multilayer filter 1; and when the mounting plate 201 is used to lock the device and the multilayer filter 1 together with screws, the fixing length of the screws will also change due to different installation environments. If the screws are too long, they will be blocked by the cooling component directly above the mounting plate 201 and cannot be installed to fix them. Therefore, the cooling component that can slide up and down can avoid the situation where the screws are too long to be installed.

[0033] Furthermore, the cooling component includes a fan support box 3 and a fan 4. The outer wall of the fan 4 can be slidably inserted into the support shell 2 and the limit plate 5 to slide up and down. The fan support box 3 is hollow inside, and two blowing channels are arranged on the outer wall. An electrically controlled fan 4 is fixedly installed at the center of each blowing channel. The blowing channel located at the front end of the support shell 2 is the air inlet, and the blowing channel located at the rear end of the support shell 2 is the air outlet.

[0034] Specifically, fans 4 are provided at the front and rear ends of the supporting shell 2, and are symmetrically distributed at the front and rear ends of the supporting shell 2. The blades of the fan 4 located at the front end of the supporting shell 2 are arranged in a manner that the fan 4 blows wind into the supporting shell, and the blades of the fan 4 located at the rear end of the supporting shell 2 are arranged in a manner that the fan 4 blows wind out of the supporting shell 2.

[0035] The fan 4 blows the external cold air into the heat dissipation device and mixes it with the heated gas inside the supporting shell 2 to cool down the space inside the supporting shell 2; the fan 4 at the rear end of the supporting shell 2 blows the warm air accumulated after neutralization inside the supporting shell 2 out of the device to quickly dissipate the heat inside the supporting shell 2, and the wind flow directions of the two cooling components are consistent.

[0036] In some embodiments, an exhaust port 202 is fixedly mounted on the top of the supporting shell 2 , and a plurality of exhaust ports 202 are evenly arranged on the top of the supporting shell 2 .

[0037] Specifically, the exhaust port 202 penetrates the top of the supporting shell 2 to allow air to circulate between the interior of the supporting shell 2 and the external environment. On the one hand, the exhaust port 202 can quickly exhaust the warm air that is neutralized by the cold air inside the supporting shell 2 when the cooling component is working. On the other hand, the exhaust port 202 can also assist in exhausting the hot air accumulated inside the supporting shell 2 when the cooling component is suddenly damaged and cannot work, thereby preventing the multilayer filter 1 from continuing to work in this state, where heat is always accumulated and cannot be discharged from the cooling component at the rear end of the supporting shell 2, causing damage.

[0038] So far, various embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution of the present invention, and the scope of the present invention is defined by the attached claims.
