Description

Technical Field

[0001] This utility model relates to the field of air-cooled condenser technology, and in particular to a filter screen for an air-cooled condenser. Background Technology

[0002] Air-cooled condensers are widely used in equipment and systems that require heat dissipation or refrigeration. They mainly remove heat through airflow. Air-cooled condensers are radiators that are used in conjunction with semi-hermetic and hermetic compressors. They are core components of Freon refrigeration equipment and are compatible with R22, R134a, and R404A refrigerants. They are mainly used in cold storage, ice making, chemical, and automotive air conditioning fields, and can be customized according to requirements.

[0003] Currently, air-cooled condensers typically use coils mounted on fins to increase the heat dissipation area. An axial fan then blows air onto the fins to increase airflow. However, in environments with poor air quality, such as those containing fibrous impurities, these impurities can easily accumulate in the fins when the axial fan blows air, reducing the equipment's ventilation efficiency and triggering overpressure alarms. Furthermore, the small and deep gaps between the fins make subsequent cleaning and maintenance of the air-cooled condenser inconvenient, increasing maintenance costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filter screen for an air-cooled condenser. This solves the problem that when an axial fan blows air onto the fins, fibrous material in the air easily accumulates in the fins, leading to a decrease in the ventilation effect of the equipment and causing an overpressure alarm. Furthermore, the small and deep gaps between the fins make subsequent cleaning and maintenance of the air-cooled condenser inconvenient and increases the cost of subsequent maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A filter screen for an air-cooled condenser includes a housing, a window plate fixedly installed on one outer wall of the housing, and multiple clips fixedly installed on both the left and right sides of the inner wall of the window plate, with a second mounting frame provided on each adjacent side of the clips.

[0007] Multiple first mounting frames are fixedly mounted on one side of multiple second mounting frames respectively. A common air-cooled condenser is provided between the rear sides of the multiple second mounting frames. The air-cooled condenser is fixedly connected to the equipment casing.

[0008] A filter assembly is mounted on a first mounting frame and a second mounting frame and is used to filter air passing through the through-hole of the window panel.

[0009] Preferably, the filtering component includes:

[0010] Multiple first filter screens are respectively snapped into the inner side of multiple second mounting frames, and multiple second filter screens are snapped into the inner side of each of the multiple first mounting frames.

[0011] Preferably, a support pad is fixedly installed at the bottom of each of the two lower card strips, and a support plate is provided between the tops of the two support pads.

[0012] Preferably, the second mounting frames are respectively connected to each other with connectors, and the other side is connected to the connector.

[0013] Preferably, a sealing groove is provided at the junction of the upper and lower sides of the multiple second mounting frames and the first mounting frame, and a rubber strip is installed in the sealing groove.

[0014] Preferably, slots are provided on both the left and right sides of the multiple second mounting frames and the first mounting frame.

[0015] Preferably, the upper and lower inner walls of the multiple second mounting frames are all fixedly installed with first limiting blocks.

[0016] Preferably, a second limiting block is fixedly installed on the inner walls of the upper and lower sides of multiple first mounting frames.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By installing a first filter plate and a second filter plate at the upper air inlet of the air condenser, dust in the air will be filtered out when air enters the equipment casing. This prevents dust from accumulating in the fins of the air condenser. When it is necessary to clean the dust from the filter components, the combination of the second mounting frame and the first mounting frame can be pulled out from the top of the retaining strip, and then the dust on the filter components can be cleaned with an air gun. This makes dust cleaning simpler and more convenient, reducing subsequent maintenance costs. Attached Figure Description

[0028] This application provides a filter screen for an air-cooled condenser, which effectively solves the problem that when an axial fan blows air onto the fins, lint in the air easily accumulates in the fins, leading to a decrease in the ventilation effect of the equipment and causing an overpressure alarm. Because the gaps between the fins are small and deep, it is very inconvenient to clean and maintain the air-cooled condenser later, increasing the cost of subsequent maintenance. Example

[0029] like Figure 1 - Figure 7 As shown, the technical solution in this application embodiment effectively solves the problem that when an axial flow fan blows air onto the fins, fibrous material in the air easily accumulates in the fins, leading to a decrease in the ventilation effect of the equipment and causing an overpressure alarm. Furthermore, the small and deep gaps between the fins make subsequent cleaning and maintenance of the air-cooled condenser inconvenient, increasing the cost of subsequent maintenance.

[0031] Equipment enclosure 1: The enclosure for equipment that requires an air-cooled condenser, such as a chiller unit and other refrigeration equipment;

[0032] First mounting frame 2: It is an aluminum alloy square frame structure, with a square mounting groove on one side for mounting the first filter screen 12;

[0033] Air condenser 3: This is an air condenser, which is fixed inside the equipment housing 1 by a metal bracket and bolts, with the upper air outlet close to the filter assembly;

[0034] Clip 4: It is a Z-shaped aluminum alloy bracket, which is fixed to the window plate 15 by bolts. It is used to limit the combination of the second mounting frame 7 and the first mounting frame 2. The combination of the second mounting frame 7 and the first mounting frame 2 can be pulled out from above.

[0040] The first limiting block 10 is a semi-cylindrical aluminum alloy block, with one end welded to the second mounting frame 7 and the other end abutting against the edge of the second filter screen 13.

[0041] The second limiting block 11 is a semi-cylindrical aluminum alloy block, with one end welded to the first mounting frame 2 and the other end abutting against the edge of the first filter screen 12.

[0042] First filter plate 12: is a stainless steel filter screen with a filter specification of 20-50 mesh;

[0043] Second filter plate 13: is a stainless steel filter screen with a filter specification of 50-100 mesh;

[0045] Window panel 15: It is a metal plate with a through hole in the middle for ventilation, and is fixed to the equipment housing 1 by bolts.

[0046] Example 1: Device housing 1

[0047] like Figure 3As shown, multiple sets of opposing clips 4 are installed on the rear side of the window panel 15, with each pair of opposing clips 4 forming one layer. Two sets of filter components are then installed between each pair of clips 4. Each filter component is clamped and fixed by a second mounting frame 7 and a first mounting frame 2. The combination of the two sets of second mounting frames 7 and first mounting frames 2 is then connected by a connector 6 and inserted from top to bottom between the opposing clips 4, thus completing the installation of one layer of filter components. The next layer is then installed in the same way. The two layers of filter components need to be sealed with rubber strips, which are installed in the sealing groove 9 to improve the sealing performance. Three or more layers can be installed.

[0048] Example 1, First Mounting Frame 2:

[0049] like Figure 4 As shown, by shortening the distance between the relatively set card strips 4, the spacing specification is the same as the length of the second mounting frame 7, then only one set of filter components and the combination of the second mounting frame 7 and the first mounting frame 2 need to be installed in one layer, and then a second layer or more can be installed, thereby changing the width range covered by the filter components.

[0050] Example 3: Air-cooled condenser

[0051] like Figure 5 As shown, by removing the bolts that fix the second mounting frame 7 and the first mounting frame 2, and then installing the first filter screen 12 only on the second mounting frame 7, the first filter screen 12 can be fixed by the second limiting block 11 on the first mounting frame 2 to hold the edge of the first filter screen 12, so that only single-layer filtration can be performed according to normal needs.

[0052] Example Card Strip 4:

[0053] like Figure 6 As shown, by removing the bolts that fix the second mounting frame 7 and the first mounting frame 2, and then installing the first filter screen 12 on the second mounting frame 7, the first filter screen 12 can be fixed by the second limiting block 11 on the first mounting frame 2 at its edge. Next, the second filter screen 13 is installed on the first mounting frame 2 and fixed by the first limiting block 10 on the second mounting frame 7. Finally, the second mounting frame 7 and the first mounting frame 2 are locked together with bolts, so that when the air passes through the through holes of the second mounting frame 7 and the first mounting frame 2, it will be filtered twice, thereby improving the filtration effect. This method is suitable for scenarios with more stringent air filtration requirements.

[0054] Working principle:

[0055] The first step is to install a first filter plate 12 and a second filter plate 13 at the upper air inlet of the air condenser 3. When air enters the equipment housing 1, the dust in the air will be filtered out by the first filter plate 12 and the second filter plate 13, thereby preventing dust from accumulating in the fins of the air condenser.

[0056] The second step involves clamping the first filter plate 12 and the second filter plate 13 using the second mounting frame 7 and the first mounting frame 2. The first limiting block 10 and the second limiting block 11 respectively abut against the second filter plate 13 and the first filter plate 12, thereby separating the first filter plate 12 and the second filter plate 13. This allows for double-layer filtration, resulting in better filtration. The first filter plate 12 or the second filter plate 13 can be disassembled according to different air filtration standards and the degree of environmental pollution, thus meeting different filtration standards. By splicing together multiple sets of filter components and the combination of the second mounting frame 7 and the first mounting frame 2, a specified number of filter components can be installed according to the different specifications of the air condenser 3.

[0057] Third, when it is necessary to clean the filter assembly, the combination of the second mounting frame 7 and the first mounting frame 2 can be directly pulled out from the top of the clip 4, and then the dust on the filter assembly can be cleaned with an air gun.

[0058] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
