Description

Technical Field

[0001] This utility model relates to the field of control equipment enclosure technology, and in particular to an enclosure structure for a control unit with cooling function. Background Technology

[0002] The control unit is the core of modern industrial automation and equipment control systems, integrating a variety of high-density electronic components such as a central processing unit, power modules, and drivers. To protect these delicate electronic components from external environmental factors such as dust, moisture, and physical impact, they are usually housed in a dedicated control box.

[0003] However, these electronic components generate a significant amount of heat during prolonged high-load operation. If this heat cannot be dissipated effectively and promptly, the temperature inside the control enclosure will rise sharply. This not only reduces the operational performance and stability of the electronic components but can also cause permanent damage due to overheating, directly impacting the reliability of the entire equipment or production line. Therefore, designing an effective heat dissipation structure for the control enclosure is crucial for ensuring the stable operation of the control unit.

[0004] Currently, the common heat dissipation method involves setting up air inlets and outlets on the enclosure and installing fans to create forced air convection, thereby removing heat. However, this universal heat dissipation design has shortcomings in practical applications. First, the layout and power of the internal heat-generating components vary between different models of control units. A universal airflow path often cannot accurately cover all critical hot spots, causing a large amount of cool air to be directly exhausted without sufficient heat exchange, resulting in both low heat dissipation efficiency and localized overheating.

[0005] In addition, to prevent dust from the external environment from entering the enclosure and contaminating electronic components, a filter is usually installed at the air inlet. Over time, the filter becomes clogged with dust, severely affecting airflow and causing a sharp decline in heat dissipation performance. Therefore, the filter must be cleaned or replaced regularly. However, in many existing designs, the filter installation and removal process is cumbersome, requiring tools and even partial disassembly of the enclosure structure. This makes maintenance time-consuming and labor-intensive, hindering quick on-site operation and consequently affecting the continuous and stable operation of the equipment. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a control unit enclosure structure with cooling function, aiming to improve the problems of low heat dissipation efficiency caused by the inability of heat dissipation airflow to accurately act on key heat-generating components, as well as the cumbersome and time-consuming process of disassembling and maintaining the air inlet filter. This utility model aims to provide a control unit enclosure with cooling function that has an improved structure and can effectively solve the above problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a control unit housing with cooling function, comprising: a control housing, an air inlet at the bottom of the control housing, an air outlet at the top of the control housing, a first fan at the air inlet, a frame for accommodating a filter screen, and a second fan at the air outlet; and a flow guiding component inside the control housing, the flow guiding component comprising a flow guiding plate.

[0008] The flow guide component is adjustablely installed inside the control box, so that the spatial position of the flow guide plate inside the control box and its tilt angle can be adjusted and fixed.

[0009] Preferably, the flow guiding component includes a slide rail fixed to the inner wall of the control box and a slide plate that slides with the slide rail, and the flow guiding plate adjusts its spatial position through the slide plate.

[0010] Preferably, the flow guiding assembly further includes a mounting plate, and the slide plate is fixed on the mounting plate; the slide rail has a plurality of threaded holes along its length, and the mounting plate is selectively locked to any of the threaded holes by bolts.

[0011] Preferably, the guide plate is rotatably connected to the slide plate via a rotating shaft to adjust its tilt angle.

[0012] Preferably, the slide plate has a plurality of threaded holes arranged in an arc-shaped array, and the guide plate is selectively locked to any one of the threaded holes by bolts.

[0013] Preferably, the air inlet of the control box is provided with a sliding groove and guide rail for the frame to be pulled out.

[0014] Preferably, the frame is provided with a locking block, and the locking block has a locking hole; the control box is provided with a locking mechanism that can be detachably engaged with the locking hole.

[0015] Preferably, the locking mechanism includes a card holder fixed to the control box, and a card rod and a spring for driving the card rod to reset are movably disposed in the card holder; the outer end of the card rod is connected to the lever, and the inner end is used to engage with the card hole.

[0016] Preferably, the air inlet is also provided with louvers.

[0017] This utility model has the following beneficial effects: In this invention, by setting an adjustable airflow guide component, the height and tilt angle of the airflow guide plate can be flexibly adjusted according to the actual position of the heating element inside the box, so as to accurately guide the cooling airflow to the key heat source, effectively avoiding cooling blind spots and local overheating, while preventing ineffective circulation of cold air, ensuring the maximum utilization of cooling energy, thereby improving the operational stability and service life of the control unit.

[0018] In this invention, the designed quick-release locking mechanism allows users to quickly pull out or fix the filter frame without any tools, simply by tossing it. This greatly reduces downtime and maintenance time required for cleaning or replacing the filter, ensuring the continuity of the filtration effect and thus ensuring the long-term stable and efficient operation of the entire heat dissipation system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 This utility model provides a control unit enclosure with a cooling function, which aims to solve the problems of low heat dissipation efficiency and inability to accurately cool specific heat-generating components in the existing control unit enclosure.

[0023] like Figure 1 As shown, the control unit housing with cooling function includes a control housing 1, an air inlet 2 at the bottom of the control housing 1, a fan 212 and a frame 202 for accommodating a filter 203 at the air inlet 2, and an air outlet 3 at the top of the control housing 1, with a fan 301 at the air outlet 3.

[0024] The control unit housing with cooling function also includes a flow guiding component 4 located inside the control housing 1. The flow guiding component 4 includes a flow guiding plate 403. The flow guiding component 4 is adjustablely installed inside the control housing 1, so that the spatial position of the flow guiding plate 403 inside the control housing 1 and its own tilt angle can be adjusted and fixed, for accurately guiding the cooling airflow drawn in by the fan 212 to the designated area.

[0025] Specifically, refer to Figure 1 and Figure 3 The flow guiding component 4 includes a slide rail 401 fixed to the inner wall of the control box 1. The flow guiding component 4 also includes a mounting plate 404. A slide plate 406 is fixedly connected to the mounting plate 404. The mounting plate 404 is slidably connected to the slide rail 401, thereby driving the slide plate 406 to move along the length direction of the slide rail 401 to adjust its spatial position. The slide rail 401 has multiple threaded holes 402 along its length direction. The mounting plate 404 is fixed at any height position on the slide rail 401 by bolts 405 passing through itself and screwing into the selected threaded holes 402.

[0026] Reference Figure 4 The guide plate 403 is rotatably connected to the slide plate 406 via the rotating shaft 407 to adjust the tilt angle of the guide plate 403. The slide plate 406 has multiple threaded holes 408 arranged in an arc-shaped array. The guide plate 403 is fixed at any tilt angle by bolts 409 passing through itself and screwing into the selected threaded holes 408.

[0027] As a preferred embodiment, in order to achieve quick assembly and disassembly of the filter 203, refer to Figure 2 The air inlet 2 of the control box 1 is provided with a slide groove 204 and a guide rail 205 for the frame 202 to be pulled out. The side of the frame 202 is slidably connected to the slide groove 204, and the bottom of the frame 202 is slidably connected to the guide rail 205. A locking block 206 is fixedly connected to the frame 202, and a locking hole 207 is opened on the locking block 206. To facilitate locking with the locking block 206, a locking seat 208 is fixedly connected to the control box 1. A locking rod 211 and a spring 209 for driving the locking rod 211 to reset are movably installed in the locking seat 208. The spring 209 is sleeved on the locking rod 211. The outer end of the locking rod 211 protrudes from the locking seat 208 and is fixedly connected to a lever 210 for easy operation by the user. The inner end of the locking rod 211 is used to engage in the locking hole 207. When the lever 210 is moved, the locking rod 211 retracts against the elastic force of the spring 209 and disengages from the locking hole 207, so that the frame 202 can be pulled out along the slide groove 204 and the guide rail 205. As another preferred embodiment, in order to perform preliminary filtration and airflow guidance on the air entering the control box 1, the outermost side of the air inlet 2 is provided with a louver 201, which is fixedly connected to the control box 1 to block larger debris from entering.

[0028] Working principle: When cooling of electronic components inside control box 1 is required, fan 212 at air inlet 2 and fan 301 at air outlet 3 are activated. Fan 212 generates suction, drawing in outside air from inlet 2. The air first passes through louvers 201, which block larger debris. Then, the air flows through filter 203 within frame 202, which filters out dust and particles. The filtered cool air then enters control box 1 and flows through airflow guide assembly 4. The pre-adjusted position and angle of the airflow guide 403 precisely guide the cool air to the area of ​​high-heat electronic components for heat exchange. As the air carrying heat rises due to its reduced density, it is eventually accelerated and discharged from the box by the fan 301 at the air outlet 3, forming a complete heat dissipation cycle. When it is necessary to clean or replace the filter 203, the operator moves the lever 210 outward. The lever 210 drives the locking rod 211 to retract against the elastic force of the spring 209, so that the inner end of the locking rod 211 is disengaged from the locking hole 207 of the lever 206. At this time, the frame 202 and the filter 203 can be pulled out together along the slide groove 204 and the guide rail 205. After maintenance, the frame 202 is pushed back to its original position, the lever 210 is released, and the spring 209 rebounds and pushes the locking rod 211 to automatically lock into the locking hole 207.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
