Description

Technical Field

[0001] This utility model relates to the field of electromechanical control cabinet technology, specifically a heat dissipation protection device for electromechanical control cabinets. Background Art

[0002] In existing electromechanical control cabinet designs, heat dissipation has always been a crucial concern. With increasing integration of electronic equipment, the components inside the control cabinet generate significant heat during operation. If this heat cannot be dissipated effectively and promptly, the internal temperature of the control cabinet will rise, affecting the performance and lifespan of electronic components and potentially causing malfunctions.

[0003] Traditional electromechanical control cabinets typically employ natural ventilation or simple fan cooling. Natural ventilation relies on ventilation holes on the cabinet surface and natural convection of outside air, resulting in low cooling efficiency and susceptibility to environmental factors. While simple fan cooling can accelerate airflow, without proper filtration, it can easily bring dust and debris into the control cabinet, causing contamination and damage to electronic components. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a heat dissipation protection device for electromechanical control cabinets to solve the problems such as dust accumulation during the heat dissipation process inside the control cabinets.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A heat dissipation protection device for an electromechanical control cabinet includes a control cabinet body, on one side of which an air inlet box and an air outlet box are arranged in sequence; the air inlet box is equipped with a plurality of fans, and the air inlet box is provided with a plurality of air inlets along the air inlet end of the fans, and each air inlet is equipped with an air inlet dust collector; the air inlet box is provided with an opening communicating with the inner cavity of the control cabinet body along the air outlet end of the fans; the air outlet box is equipped with an exhaust mesh plate around its perimeter, and an exhaust fan is provided between the exhaust box and the control cabinet body.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the air intake dust collector includes:

[0008] Main casing with reserved air inlet and exhaust outlet;

[0009] A single-port circular filter element installed inside the main housing and whose filter inlet is connected to the air inlet of the main housing;

[0010] An air inlet pipe used to connect the exhaust port of the main housing with the air inlet of the air inlet box.

[0011] Furthermore, the single-port circular filter element is detachably connected to the main housing, and the main housing is provided with a detachable cover plate along the single-port circular filter element.

[0012] Furthermore, the cover plate is equipped with a spring for pressing and securing the single-port circular filter element.

[0013] Furthermore, a guide pipe is connected to the filter inlet of the single-port circular filter element; the air inlet of the main housing forms a sleeve that matches the guide pipe.

[0014] Furthermore, the inner wall of the sleeve is provided with a sealing ring that contacts the guide tube.

[0015] Furthermore, several air guide plates are installed at the reserved opening of the air inlet box.

[0016] Furthermore, the heat dissipation protection device for the electromechanical control cabinet provided by this utility model has at least the following beneficial effects compared with the prior art:

[0017] The intake fan accelerates the flow of cool outside air and sends it into the control cabinet cavity for direct and efficient cooling of the internal components. Subsequently, the hot air is rapidly exhausted through the exhaust fan and exhaust box, forming a complete air circulation path from intake to exhaust, ensuring effective temperature control inside the control cabinet.

[0018] An air intake dust collector is installed at the air inlet of the air intake box. This dust collector effectively filters out dust and impurities from the air through a single-port circular filter element, ensuring that the air entering the control cabinet is clean and uncontaminated. This not only protects the internal components from dust damage but also extends the service life of the components. Attached Figure Description

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed structures. Those skilled in the art can understand the specific meaning of these terms in this patent based on the specific circumstances.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the heat dissipation protection device for the electromechanical control cabinet of this utility model includes a control cabinet body 1. An air inlet box 2 and an exhaust box 3 are arranged sequentially on one side of the control cabinet body 1. The air inlet box 2 is equipped with several air supply fans 4. The air inlet box 2 has several air inlets along the air inlet end of the air supply fans 4, and each air inlet is equipped with an air intake dust collector 5. An opening is reserved along the air outlet end of the air supply fans 4 to communicate with the inner cavity of the control cabinet body 1. The exhaust box 3 is equipped with an exhaust mesh plate 7 around its perimeter, and an exhaust fan 6 is arranged between the exhaust box 3 and the control cabinet body 1.

[0027] Outside cold air is introduced through the air inlet on the air inlet box 2. The air inlet dust collector 5 installed at the air inlet effectively filters out dust and impurities in the air, ensuring that the air entering the control cabinet 1 is clean. Subsequently, the exhaust fan 4 accelerates the flow of the cleaned air and sends it into the inner cavity of the control cabinet 1 to cool and dissipate heat from the internal components.

[0028] The cooled hot air is discharged through the exhaust box 3, which is located on the opposite side of the control cabinet 1 and the air inlet box 2. The exhaust mesh 7 on the exhaust box 3 further prevents foreign objects from entering while allowing hot air to be discharged smoothly. The exhaust fan 6 is installed between the exhaust box 3 and the control cabinet 1 to accelerate the discharge process of hot air, forming a complete air circulation path from the air inlet box 2 to the exhaust box 3, thereby achieving effective heat dissipation and dust protection for the inside of the electromechanical control cabinet.

[0029] In one embodiment, the air intake dust collector 5 includes:

[0030] 5.1 Main casing with reserved air inlet and exhaust outlet;

[0031] A single-port circular filter element 5.2 is installed inside the main housing 5.1 and its filter inlet is connected to the air inlet of the main housing 5.1;

[0032] An air inlet pipe 5.3 is used to connect the exhaust port of the main housing 5.1 with the air inlet of the air inlet box 2.

[0033] Secondly, the single-port circular filter element 5.2 is detachably connected to the main housing 5.1, and the main housing 5.1 is provided with a detachable cover plate 5.4 along the single-port circular filter element 5.2.

[0034] In addition, the cover plate 5.4 is equipped with a spring 5.5 for pressing and securing the single-port circular filter element 5.2.

[0035] The air intake dust collector 5 mainly consists of a main housing 5.1, a single-port circular filter element 5.2, and an air intake pipe 5.3, forming a high-efficiency air filtration unit. When outside air enters through the air inlet of the air intake box 2, it first enters the main housing 5.1 of the air intake dust collector 5. The main housing 5.1 has reserved air inlets and exhaust outlets for air intake and filtered air exhaust, respectively.

[0036] The single-port circular filter element 5.2 is a key component for air filtration. Its filter inlet is tightly connected to the air inlet of the main housing 5.1, ensuring that all incoming air must be filtered by the filter element. The filter element is designed to effectively block dust, particulate matter, and other impurities in the air, allowing only clean air to pass through.

[0037] To facilitate maintenance and filter replacement, the single-port circular filter element 5.2 is detachably connected to the main housing 5.1. A detachable cover 5.4 is provided on the main housing 5.1 along the filter element location, allowing for easy removal or installation of the filter element by opening or closing the cover.

[0038] In addition, to ensure that the filter element is securely fixed inside the main housing after installation and to prevent loosening or displacement due to airflow impact, a spring 5.5 is also installed on the cover plate 5.4. The function of the spring is to apply a certain pressure to the filter element, so that it fits tightly against the air inlet of the main housing, improving the filtration effect while also ensuring the stability and durability of the filter element.

[0039] As a supplement, the filter inlet of the single-port circular filter element 5.2 is connected to a guide pipe 5.6; the air inlet of the main housing 5.1 forms a sleeve 5.7 that matches the guide pipe 5.6.

[0040] A sleeve 57 matching the guide tube 56 is designed at the air inlet of the main housing 5.1 to ensure that the guide tube can be accurately and securely connected to the main housing.

[0041] The inner wall of the sleeve 5.7 is provided with a sealing ring that contacts the guide tube 5.6. The sealing ring can fit tightly against the outer wall of the guide tube 5.6, effectively preventing air leakage when passing through the interface, thereby ensuring that all air entering the main housing 5.1 must be filtered by the filter element 5.2.

[0042] In one implementation, a number of air guide plates 2.1 are installed at the reserved opening of the air inlet box 2. The air guide plates 2.1, through their specific shape and arrangement, can guide the air entering from the air inlet of the air inlet box 2 to flow to the inner cavity of the control cabinet 1 along a predetermined path and speed.
