Description

Technical Field

[0001] This utility model relates to the field of drawer cabinet technology, specifically a drawer cabinet. Background Technology

[0002] Drawer cabinets are a type of low-voltage switchgear, and are large, fixed-installation electrical distribution units. With the development of industrial automation, drawer cabinets, as a safe and convenient storage solution for electrical control equipment, are widely used in various industrial production fields.

[0003] Current drawer chests are equipped with heat dissipation devices to address the issue of heat buildup inside. However, existing heat dissipation devices generally use a direct-vent design, which has significant drawbacks in actual operation.

[0004] The airflow path of a direct-ventilation cooling system is directly exposed, making it easy for dust from the environment to be drawn in and adhere to the fan blades. As dust accumulates, the cooling efficiency of the fan blades decreases, ultimately affecting the overall cooling performance of the drawer unit and making it impossible to effectively control the temperature inside. Summary of the Invention

[0005] The purpose of this utility model is to provide a drawer cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drawer cabinet, comprising a cabinet body, the cabinet body being composed of a fixed frame, side panels, and a rear panel. Side panels are fixedly connected to the left and right sides of the outer wall of the fixed frame via fasteners. A rear panel is fixedly connected to the rear end of the fixed frame via fasteners. Multiple arc-shaped openings are provided on both sides of the surface of the rear panel, forming a heat dissipation channel between the arc-shaped openings and the side panels. A heat dissipation device is fixedly installed on the surface of the fixed frame at a position opposite to the heat dissipation channel. The heat dissipation device includes a mounting bracket, a baffle, and cooling fans. The mounting bracket is installed on the outer wall surface of the fixed frame via fasteners. A baffle is connected to the front end of the mounting bracket. Multiple cooling fans are installed on the surface of the mounting bracket at the baffle. A heat dissipation vent is formed between the mounting bracket and the baffle, and the heat dissipation vent communicates with the heat dissipation channel.

[0007] Preferably, the mounting bracket includes a mounting plate and a fixing plate. The mounting plate is fixedly connected to the top of the fixing plate. The surface of the fixing plate has multiple mounting positions. A cooling fan is installed in each mounting position. Fixing studs are fixedly connected to the surface of the fixing plate above and below the mounting positions. The surface of the mounting plate has multiple mounting holes and is connected and fixed to the fixing frame through the mounting holes.

[0008] Preferably, the baffle includes a wind deflector and a connecting plate. Two inwardly bent connecting plates are symmetrically fixedly connected to the surface of the wind deflector, and the wind deflector and the connecting plates have a U-shaped structure design. The surface of the connecting plate is provided with a connecting hole adapted to the fixing stud.

[0009] Preferably, the connecting hole is connected to the fixing stud, and the mounting bracket and the baffle are fixed by the threaded connection of the fixing stud with a nut.

[0010] Beneficial effects

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model utilizes the arc-shaped openings on both sides of the rear baffle to form a specific heat dissipation channel with the side baffle. Combined with the heat dissipation vents formed by the mounting bracket and baffle in the heat dissipation device, it changes the traditional design of directly exposed airflow paths in direct-vent heat dissipation devices. This structure guides and blocks the air entering the cabinet, significantly reducing the probability of dust being drawn in and adhering to the fan blades. It avoids the problem of reduced heat dissipation efficiency due to dust accumulation, thus ensuring the long-term stability of the entire drawer cabinet's heat dissipation performance and ensuring the internal temperature is always controlled within a reasonable range, providing a good temperature environment for the stable operation of electrical control equipment.

[0013] 2. In this utility model's heat dissipation device, the mounting plate of the mounting bracket has multiple mounting positions for installing cooling fans. The arrangement of multiple cooling fans enhances airflow speed and volume. Simultaneously, the design of the heat dissipation channel and the heat dissipation vent creates a smooth airflow path, allowing heat inside the cabinet to be quickly and orderly expelled from the cabinet through the heat dissipation channel and vent. Compared to traditional direct-vent heat dissipation, this utility model's heat dissipation structure is more targeted and efficient, further improving the overall heat dissipation efficiency of the drawer cabinet and effectively handling the large amounts of heat generated by electrical equipment during operation in industrial production.

[0014] 3. In terms of installation, the cabinet's fixed frame, side panels, and rear panel are all fixedly connected by fasteners. The mounting bracket for the heat dissipation device is connected and fixed to the fixed frame through mounting holes on the surface of the mounting plate. The panels are connected by inserting and connecting holes on the surface of the connecting plate to the matching fixing studs, and then secured with nuts. The entire installation process is clear and straightforward, and the connection method used is simple and reliable, requiring no complex special tools, reducing assembly difficulty, and facilitating quick assembly by workers. At the same time, this modular installation structure also provides convenience for subsequent maintenance. When it is necessary to repair or replace components such as the cooling fan, only the corresponding fasteners need to be removed, reducing maintenance time and costs and improving maintenance efficiency.

[0015] 4. This utility model's mounting bracket is composed of a mounting plate and a fixing plate fixedly connected together. The baffle uses a windproof plate and an inwardly bent connecting plate to form a U-shaped structure. This structural design not only enhances its own structural strength but also makes the connection between the heat dissipation device and the cabinet body more stable. The tight connection between the side baffle, rear baffle, and fixing frame, as well as the reliable fixation of the heat dissipation device to the fixing frame, jointly improve the structural stability and resistance to external forces of the entire drawer cabinet. In the vibration and collision environments that may exist in industrial production sites, it can effectively prevent parts from loosening or being damaged, ensuring the overall reliability and service life of the drawer cabinet and reducing the risk of equipment failure.

[0027] Example 1

[0028] like Figure 1-4 This is a schematic diagram of a drawer cabinet according to a preferred embodiment of the present invention. In this embodiment, the drawer cabinet includes a cabinet body 1. The cabinet body 1 consists of a fixed frame 2, side panels 3, and a rear panel 4. The fixed frame 2 is welded from metal profiles and has sufficient structural strength. The side panels 3 are fixedly connected to the left and right sides of the outer wall of the fixed frame 2 by bolts or other fasteners. The side panels 3 are metal plates, and their dimensions match the sides of the fixed frame 2. The rear end of the fixed frame 2 is fixedly connected to the rear end of the fixed frame 2 by bolts or other fasteners. The rear panel 4 is also a metal plate and covers the rear opening of the fixed frame 2.

[0029] In this embodiment, multiple arc-shaped openings 41 are formed on both sides of the rear baffle 4. The arc-shaped openings 41 are semi-circular openings and are evenly distributed along the vertical direction of the rear baffle 4. A heat dissipation channel 5 is formed between the arc-shaped openings 41 and the inner wall of the side baffle 3. The heat dissipation channel 5 is a narrow space for air circulation. A heat dissipation device 6 is fixedly installed on the surface of the fixing frame 2 at the position opposite to the heat dissipation channel 5 by bolts.

[0030] In this embodiment, the heat dissipation device 6 includes a mounting bracket 61, a baffle 62, and cooling fans 63. The mounting bracket 61 is bolted to the outer wall surface of the fixed frame 2. The front end of the mounting bracket 61 is connected to the baffle 62. Multiple cooling fans 63 are mounted on the surface of the mounting bracket 61 at the baffle 62, wherein the cooling fans 63 are axial flow fans, and there are three of them arranged in parallel. A heat dissipation opening 64 is formed between the mounting bracket 61 and the baffle 62. The heat dissipation opening 64 is a transverse slit and communicates with the heat dissipation channel 5, allowing air to enter the heat dissipation channel 5 from the heat dissipation opening 64.

[0031] Specifically, the mounting bracket 61 includes a mounting plate 612 and a fixing plate 611. The fixing plate 611 is a rectangular metal plate, and the mounting plate 612 is fixedly connected to its top by welding. The mounting plate 612 is a Z-shaped folded plate. Multiple mounting positions 613 are formed on the surface of the fixing plate 611. Each mounting position 613 is a circular through hole, the size of which matches the housing of the cooling fan 63. The cooling fan 63 is fixed in the mounting position 613 by screws. Above and below the mounting positions 613, fixing studs 614 are welded to the surface of the fixing plate 611. The fixing studs 614 are threaded metal posts. Multiple mounting holes 615 are formed on the surface of the mounting plate 612, and these holes are bolted to the corresponding threaded holes on the fixing frame 2.

[0032] The baffle 62 includes a wind deflector 621 and a connecting plate 622. The wind deflector 621 is a rectangular metal plate, and two inwardly bent connecting plates 622 are symmetrically fixedly connected to its surface. The connecting plates 622 and the wind deflector 621 are integrally bent. The wind deflector 621 and the connecting plates 622 have a U-shaped structure design. The surface of the connecting plate 622 has a connecting hole 623 adapted to the fixing stud 614. The connecting hole 623 is a circular through hole.

[0033] During assembly, the connecting hole 623 of the baffle 62 is inserted into the fixing stud 614 of the mounting bracket 61, and then a nut is threaded onto the fixing stud 614 to fix the mounting bracket 61 and the baffle 62. At this time, a heat dissipation vent 64 is formed between the baffle 621 and the fixing plate 611.

[0034] Working principle: When the cooling fan 63 is working, air inside the cabinet 1 is drawn in through the heat dissipation vent 64, accelerated by the cooling fan 63, enters the heat dissipation channel 5, and is discharged outside the cabinet 1 through the arc-shaped opening 41 on the rear baffle 4. Simultaneously, hot air inside the cabinet 1 is drawn into the heat dissipation channel 5 under the influence of pressure difference, forming a continuous airflow, thereby achieving effective heat dissipation inside the cabinet 1. The concave structure of the baffle 62 can block directly entering dust, reducing dust accumulation on the blades of the cooling fan 63.

[0035] Example 2

[0036] Based on Embodiment 1, this embodiment further optimizes the structure of the heat dissipation channel 5. The number of arc-shaped openings 41 on the rear baffle 4 is increased to six on each side, and the diameter of the arc-shaped openings 41 is slightly larger than that in Embodiment 1, so as to increase the cross-sectional area of ​​the heat dissipation channel 5 and improve the airflow. The number of cooling fans 63 is correspondingly increased to four to enhance the heat dissipation effect. Other structures and assembly methods are the same as in Embodiment 1.

[0037] Example 3

[0038] Based on Example 1, this example improves the material of the baffle 62. The wind baffle 621 and the connecting plate 622 are made of stainless steel to improve corrosion resistance and structural strength, making them suitable for humid or corrosive environments. Other structures and assembly methods are the same as in Example 1.

[0039] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
