Description

Technical Field

[0001] This utility model relates to the field of network cabinet technology, specifically a network cabinet that utilizes an arc-shaped air guide mechanism to improve heat dissipation performance. Background Technology

[0002] Network cabinets are core infrastructure in the communications and data center fields, mainly used to store and organize network equipment such as servers, switches, and firewalls. The equipment layout inside network cabinets is relatively dense. When running continuously and exposed to high temperatures for extended periods, it is prone to equipment performance degradation, hardware wear and tear, data errors, and even system crashes, causing severe network paralysis. Existing network cabinets use straight-panel air ducts, which direct the incoming cool air directly towards the front door of the cabinet. After colliding with the front door, the cool air disperses, resulting in uneven distribution of cool air to each device, thus affecting the overall heat dissipation effect. To address this, a network cabinet with an arc-shaped air guide mechanism is proposed to improve heat dissipation performance. Utility Model Content

[0003] The main purpose of this utility model is to provide a solution that can effectively address the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a network cabinet that improves heat dissipation performance using an arc-shaped air guide mechanism, comprising a cabinet body, a front door, a rear door and a side door set on the cabinet body, an air inlet set at the bottom of the cabinet body, a pull-out plate set on the air inlet for adjusting the size of the air inlet, and a plurality of mounting columns set inside the cabinet body. The feature is that it further includes an arc-shaped air guide device installed on the mounting columns and located above the air inlet to facilitate airflow. The arc-shaped air guide device includes an S-shaped arc plate, side plates set on the left and right sides of the S-shaped arc plate, and a connecting plate hanging from the side plates for fixed connection with the mounting columns. One end of the S-shaped arc plate is attached to the bottom of the cabinet body, and the other end has an upward arc forming a horizontal S-shape.

[0005] Preferably, the mounting column is provided with a guide plate to guide the airflow direction.

[0006] Preferably, the top of the cabinet is provided with several heat dissipation holes.

[0007] Preferably, the front door is a sealed door and the rear door is a mesh door.

[0008] Preferably, the cabinet is symmetrically equipped with sealing plates to prevent cold air from leaking out. After the cold air is blown out from the arc-shaped air guide device, it enters the cold air channel formed by the sealing plate, the mounting column, and the front door.

[0009] Preferably, the mounting column is equipped with L-shaped spacers and partitions for placing equipment.

[0010] This utility model has the following beneficial effects: By setting up an arc-shaped air guide device, when cold air enters the cabinet from the inlet at the bottom of the cabinet, the cold air first enters the positive arc surface of the arc-shaped air guide device, and then smoothly transitions to the negative arc surface. The arc surface attached to the S-shaped arc plate flows upward, allowing the cold air to enter the cold air channel formed by the mounting column and the front door along the negative arc surface. The setting of the positive and negative double arc surfaces reduces the airflow resistance and optimizes the airflow path, thereby accelerating the airflow speed. This allows the cold air entering the cold air channel to pass through the equipment at a uniform speed without interruption, dissipating the heat inside the equipment, improving the heat dissipation effect of the cabinet, ensuring that the equipment inside the cabinet can operate stably and continuously, ensuring the stability of the network, and preventing the blown cold air from blowing to the front door, causing the airflow to hit the front door and disperse, failing to enter the equipment evenly for heat dissipation.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-3 As shown, a network cabinet that utilizes an arc-shaped air guide mechanism to improve heat dissipation performance includes a cabinet body 1, a front door 2, a rear door 3, and a side door 4 mounted on the cabinet body 1, an air inlet 5 located at the bottom of the cabinet body 1, a pull-out plate 6 mounted on the air inlet 5 for adjusting the size of the air inlet 5, and several mounting columns 7 mounted inside the cabinet body 1. The cabinet is characterized by further including an arc-shaped air guide device 8 mounted on the mounting columns 7 and located above the air inlet 5 to facilitate airflow. The arc-shaped air guide device 8 includes an S-shaped arc plate 81, side plates 82 located on the left and right sides of the S-shaped arc plate 81, and connecting plates 83 hanging from the side plates 82 for fixed connection with the mounting columns 7. One end of the S-shaped arc plate 81 is attached to the bottom of the cabinet body 1, and the other end forms a horizontal S-shape with the arc opening upwards.

[0017] With the arc-shaped air guide device 8 in place, when cold air enters the cabinet 1 from the inlet air 5 at the bottom of the cabinet 1, the cold air first enters the forward arc surface of the arc-shaped air guide device 8, and then smoothly transitions to the reverse arc surface. It flows upward along the arc surface attached to the S-shaped arc plate 81, allowing the cold air to enter the cold air channel formed by the mounting column 7 and the front door 2 along the reverse arc surface. The design of the forward and reverse arc surfaces reduces the airflow resistance and optimizes the airflow path, thereby accelerating the airflow speed. This allows the cold air entering the cold air channel to pass through the equipment at a uniform speed without interruption, dissipating the heat inside the equipment and improving the heat dissipation effect of the cabinet 1. This ensures that the equipment inside the cabinet 1 can operate stably and continuously, guarantees the stability of the network, and prevents the blown cold air from blowing towards the front door 2, causing the airflow to collide with the front door 2 and disperse, thus failing to enter the equipment evenly for heat dissipation.

[0018] In one embodiment, the mounting column 7 is provided with a baffle plate 9. When the equipment in the cabinet 1 is not fully loaded, the gap between the equipment can be sealed by the baffle plate 9 to prevent cold air from entering through the gap between the equipment, thereby reducing some of the cold air and thus reducing the heat dissipation effect. The baffle plate 9 can store cold air in the cold air channel and dissipate heat to the equipment continuously and at a uniform speed, increasing the utilization rate of cold air and thus improving the heat dissipation of the equipment. At the same time, the baffle plate 9 is available in various specifications, such as 1U, 2U, 3U, 4U, 5U, etc., to meet the sealing of different gaps.

[0019] In one embodiment, the top of the cabinet 1 is provided with several heat dissipation holes 13; the front door 2 of the cabinet 1 is a sealed door, and the rear door 3 is a mesh door; the cabinet 1 is symmetrically provided with sealing plates 12 to prevent cold air from leaking out. After the cold air is blown out from the arc-shaped air guide device 8, it enters the cold air channel formed by the sealing plate 12, the mounting column 7, and the front door 2; when the cold air is blown upward from the arc-shaped air guide device 8, it enters the cold air channel and is split along the direction of the equipment. The cold air passes through the equipment, takes away the heat on the equipment, and is blown out from the heat dissipation holes 13 on the top of the cabinet 1 and the mesh of the rear door 3.

[0020] In one embodiment, the mounting column 7 is equipped with an L-shaped spacer 10 and a partition 11 for placing equipment. The installation positions of the L-shaped spacer 10 and the partition 11 are set according to the height of the equipment. The partition 11 is suitable for the installation of equipment that is narrow and heavy, while the L-shaped spacer 10 is suitable for the installation of equipment that is light and wide. When installing the equipment, the connecting pieces on both sides of the equipment need to be installed on the mounting column 7 first, and then the equipment is placed on the L-shaped spacer 10. The equipment is supported by the connection with the mounting column 7 and the L-shaped spacer 10. The support capacity is less than or equal to the support capacity of the partition 11, but it has good heat dissipation, is lightweight, and is easy to install.

[0021] When using this utility model, first open the pull-out plate 6 at the bottom of the cabinet 1. Cold air enters from the air inlet 5 at the bottom of the cabinet 1 and rises along the S-shaped arc plate 81 of the arc-shaped air guide device 8, entering the cold air channel formed between the mounting column 7 and the front door 2. Then, guided by the guide plate 9, it enters the equipment, dissipating the heat generated during equipment operation. The cold air becomes hot air and is blown out from the heat dissipation hole 11 at the top of the cabinet 1 and the mesh of the rear door 3.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
