Description

Technical Field

[0001] This utility model relates to the technical field of cabinet heat dissipation, and specifically discloses a cabinet heat dissipation structure. Background Technology

[0002] Server racks are essential devices used to house electronic equipment, servers, communication equipment, and other electrical devices. They are widely used in data centers, communication base stations, industrial control systems, and other fields. The main functions of server racks are to provide physical support for the equipment, protect it from external interference, and facilitate equipment management and maintenance. With the rapid development of electronic technology, the number of devices within server racks is constantly increasing, and the heat generated by these devices is also growing. Therefore, effectively solving the heat dissipation problem within server racks and ensuring that the equipment operates within its normal temperature range has become a key aspect of server rack design.

[0003] Server racks typically employ air-cooling, which involves installing an exhaust fan on one side of the rack to remove heat generated by the equipment through airflow. This method offers advantages such as system simplicity, easy installation, and low failure rate. However, existing exhaust-based cooling structures have some drawbacks. Because the exhaust fan is only located on one side of the rack, the airflow path is limited, resulting in less than ideal ventilation. Heat generated by equipment on the side of the rack furthest from the exhaust fan often cannot be dissipated promptly, easily accumulating and causing overheating. This localized overheating can affect equipment performance and may even lead to equipment failure and shorten its lifespan. Therefore, a new server rack cooling structure is needed to address the problems of existing cooling methods, improve the overall cooling effect of the rack, and ensure the stable operation of the equipment within the rack. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a heat dissipation structure for a server rack.

[0005] This utility model discloses a heat dissipation structure for a server rack, which adopts the following technical solution:

[0006] A heat dissipation structure for a server rack includes: a server rack, in which electrical equipment is installed, a ventilation box on the server rack, a condenser and an air inlet channel at a first end of the ventilation box, a second end of the ventilation box communicating with the inside of the server rack, an air supply device on the air inlet channel, an air supply duct inside the server rack, an air inlet of the air supply duct connected to the air inlet channel, and an air outlet of the air supply duct extending to the side of the electrical equipment away from the ventilation box.

[0007] Preferably, the cabinet is equipped with an exhaust fan, which is located on the side of the electrical equipment near the ventilation box.

[0008] Preferably, the ventilation equipment is provided at intervals.

[0009] Preferably, the air supply duct has multiple air outlets.

[0010] Preferably, the air supply duct has multiple branch ducts.

[0011] Preferably, the air outlet of the air supply duct is located at the middle height of the cabinet.

[0012] Preferably, the cabinet includes a cabinet body and a cabinet door, the ventilation box is disposed on the cabinet door, the air supply duct is disposed inside the cabinet body, the air inlet of the air supply duct is located on the side of the cabinet body facing the cabinet door, and the air inlet outlet of the ventilation box is located on the side of the cabinet door facing the cabinet body. When the cabinet door is closed, the air inlet channel is connected to the air supply duct.

[0013] Preferably, the second end of the ventilation box is provided with an air distribution plate, and the air distribution plate is provided with several through holes.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] This invention utilizes a condenser, air intake channel, air supply duct, and air supply equipment installed within the cabinet. The condenser cools the air inside the ventilation box, and the air supply equipment draws the air from the ventilation box through the air intake channel to the air supply duct. The air supply duct then transports the cooled air from the side of the electrical equipment closest to the ventilation box to the side furthest away. This not only allows the heat on the side of the electrical equipment closest to the ventilation box to be dissipated by the exhaust air, but also allows the heat accumulated on the back side of the electrical equipment to be absorbed and dissipated to the ventilation box on the front side by the air supply equipment. The condenser then continues to cool the hot air, and the condensed cooled air is then transported back to the back of the electrical equipment through the air supply duct, thus achieving cyclical heat dissipation.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] A heat dissipation structure for a server rack, referring to Figure 1-3 It includes: a cabinet 1, which houses electrical equipment; a ventilation box 2 on the cabinet 1; a condenser 4 and an air inlet channel 3 at the first end of the ventilation box 2; the second end of the ventilation box 2 connected to the inside of the cabinet 1; an air supply device 5 on the air inlet channel 3, which may be a fan; an air supply duct 6 inside the cabinet 1; the air inlet of the air supply duct 6 connected to the air inlet channel 3; and the air outlet 61 of the air supply duct 6 extending to the side of the electrical equipment away from the ventilation box 2. Unlike traditional rack cooling systems that only have air supply equipment, this solution uses a condenser 4, an air intake channel 3, and an air supply duct 6 in conjunction with an air supply device 5 within the rack 1. The condenser 4 cools the air inside the ventilation box 2, and the air supply device 5 draws the air from the ventilation box 2 through the air intake channel 3 to the air supply duct 6. The air supply duct 6 then transports the cool air from the side of the electrical equipment closest to the ventilation box 2 to the side furthest away. This allows heat accumulated on the back side of the electrical equipment to be absorbed and dissipated into the ventilation box 2 by the air supply device 5. The condenser 4 then continues to cool the hot air, and the condensed cool air is then transported back to the back of the electrical equipment through the air supply duct 6, thus achieving cyclic cooling. This solves the problem of limited cooling area in traditional rack cooling fans. This solution provides better cyclic radiative cooling and can better cool multiple electrical devices within the rack.

[0023] As a preferred embodiment, the cabinet 1 is also equipped with an exhaust fan 7, which can be a fan. The exhaust fan 7 is located on the side of the electrical equipment near the ventilation box 2. Multiple exhaust fans 7 can be installed at intervals, with each exhaust fan 7 corresponding to one of the electrical devices placed in the cabinet 1. By adopting the above design, cool air is delivered to the back of the electrical equipment through the air outlet 61 of the air supply duct 6. The exhaust fan can better improve the heat dissipation and ventilation effect of cool air from the back to the front of the electrical equipment. Moreover, the exhaust fan 7 corresponding to each electrical device can more evenly draw cool air to the corresponding areas, thereby improving the heat dissipation uniformity of the cabinet.

[0024] As a preferred option, the air outlet 61 of the air supply duct 6 is provided with multiple outlets, as shown in the reference. Figure 3In this embodiment, the air supply duct 6 has two main branch ducts, each of which has four secondary branch ducts. The four branch ducts form four air outlets 61, which are arranged facing the upper left, lower left, upper right, and lower right, respectively. In addition, the air outlets 61 are located at the middle height of the cabinet 1. By adopting the above design, the cool air from the air supply duct 6 can be delivered more quickly and evenly to all directions behind the electrical equipment in the cabinet 1, thereby improving the rapid and uniform heat dissipation effect.

[0025] As a preferred embodiment, the cabinet 1 includes a cabinet body 11 and a cabinet door 12. A ventilation box 2 is mounted on the cabinet door 12, and an air supply duct 6 is installed inside the cabinet body 11. The air inlet of the air supply duct 6 is located on the side of the cabinet body 11 facing the cabinet door 12, and the air inlet channel 3 of the ventilation box 2 is located on the side of the cabinet door 11 facing the cabinet 12. When the cabinet door is closed, the air inlet channel 3 and the air supply duct 6 are perfectly aligned. This design allows personnel to perform maintenance and repairs on the air supply equipment by opening the cabinet door. Furthermore, there is no need for a fixed connection between the air supply duct 6 and the air inlet channel 3; simply closing the cabinet door establishes the connection, making operation more convenient.

[0026] As a preferred embodiment, the second end of the ventilation box 2 is provided with a wind distribution plate 21, which has several through holes. The heat from the electrical equipment is absorbed by the air supply device 5 and enters the air cavity of the ventilation box 2 through the through holes on the wind distribution plate 21, thus avoiding the problem of rapid air extraction in some areas while slow air extraction in others. The wind distribution plate 21 plays a role in further uniform heat dissipation.

[0027] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
