Description

Technical Field

[0001] This utility model relates to the technical field of server rack heat dissipation devices, and in particular to a heat dissipation device for IDC server racks. Background Technology

[0002] IDC (Internet Data Center) server racks are dedicated cabinets in data centers used to install and store servers, network equipment, and other IT equipment. They are an important component of data center infrastructure, providing fixed storage space for servers, network switches, routers, storage devices, and more. The equipment inside the racks generates heat during operation, necessitating the installation of cooling systems within the racks.

[0003] By setting up an air duct that connects multiple server racks and supplying cool air through it, cool air can be distributed to multiple racks. However, the load on the servers in each rack varies. Some racks may be running high-load applications, such as big data processing and high-performance computing, which generate more heat. Other racks may be running low-load applications, generating relatively less heat. Therefore, the heat output of each rack differs, and the amount of cool air required also varies. Thus, it is necessary to rationally allocate the cool air within each rack based on its specific characteristics. Utility Model Content

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, this utility model proposes a heat dissipation device for IDC server room cabinets, including multiple cabinets 1 and a cold air pipe 2 fixedly installed at the bottom of the cabinet 1 and a warm air pipe 201 fixedly installed at the top of the cabinet 1. A cooling device and a fan device are installed at one end of the cold air pipe 2. The fan device can deliver gas into the interior of the cold air pipe 2, and the cooling device can cool the gas. The warm air pipe 201 can be connected to the air inlet of the fan device (the cooling device and fan device are existing technologies and will not be described in detail here). It also includes an air inlet slot 101 and an exhaust slot 102 located inside the cabinet 1, as well as a mounting cavity 103. Multiple servers 6 are fixedly installed in the mounting cavity 103, and a flow cavity 601 is provided between adjacent servers 6. The air inlet slot 101 and the mounting cavity 103 are interconnected, and the exhaust slot 102 and the mounting cavity 103 are interconnected. The air intake slot 101 is equipped with an air inlet 104 that communicates with the cold air pipe 2, and the exhaust slot 102 is equipped with an exhaust outlet 105 that communicates with the heating pipe 201. When cold air enters the cold air pipe 2, it will enter the air intake slot 101 through the air inlet 104. The cold air entering the air intake slot 101 will then enter the exhaust slot 102 through the flow chamber 601, allowing the cold air to come into contact with the server 6 and exchange heat with it, thereby achieving the purpose of dissipating heat from the server 6. Subsequently, the heated air will enter the heating pipe 201.

[0025] This embodiment also includes an air volume control component, which is installed on one side of the air inlet 104. The air volume control component controls the amount of air entering the air inlet 101 through the cooling air pipe 2. The air volume control component includes a first push rod motor 3 fixedly installed inside the cabinet 1, and a first sealing plate 301 slidably installed inside the air inlet 104. The output shaft of the first push rod motor 3 is fixedly connected to the first sealing plate 301. It should be noted that, according to the principles of fluid mechanics, especially Bernoulli's equation and orifice outflow theory, when the air pressure inside the box is constant and the gas flow is at a low speed (incompressible fluid and low Reynolds number), the amount of air (flow rate) through each orifice is related to the size (area) of the orifice. Specifically, the amount of air through each orifice is proportional to the size (area) of the orifice.

[0026] In this embodiment, the first push rod motor 3 pushes the first sealing plate 301 to move, which can block the air inlet 104. This changes the size of the air inlet 104, thereby controlling the size of the air inlets 104 on multiple cabinets 1. Based on the size relationship of the air inlets 104 on different cabinets 1, the amount of air entering different cabinets 1 can be controlled to be different while keeping the output power of the fan device constant. Therefore, the cooling air can be reasonably distributed according to the heat dissipation required by different cabinets 1 in the current working environment. The heat dissipation needs of different cabinets can be met while keeping the output power of the fan device constant. This prevents the air velocity inside multiple cabinets 1 from increasing simultaneously when the heat dissipation demand inside one cabinet 1 increases, thereby effectively reducing the energy consumption of the fan device.

[0027] This embodiment also includes a local heat dissipation auxiliary mechanism, which is installed inside the air inlet slot 101. The local heat dissipation auxiliary mechanism controls the gas flow rate in any part of the mounting cavity 103. The local heat dissipation auxiliary mechanism includes a fan shroud 4 slidably installed inside the air inlet slot 101. Multiple flexible hoses 401 are fixedly installed on the fan shroud 4. An air duct 402 is fixedly installed on the cabinet 1. The air duct 402 is located inside the cooling pipe 2 and communicates with the flexible hoses 401. The air duct 402 is provided with an air inlet slot 403. A closing component that controls the opening size of the air inlet slot 403 is installed on the air duct 402. Servers 6 inside the same cabinet 1 may experience localized overheating due to different loads and types. Therefore, it is necessary to enhance the heat dissipation of this area. The cold air inside the air duct 2 will enter the hose 401 through the air duct 402, and then enter the fan hood 4 through the hose 401 for exhaust. Finally, it will be exhausted through the fan hood 4, thereby increasing the airflow at the fan hood 4 and thus enhancing the heat dissipation effect at the fan hood 4. Furthermore, the airflow through the fan hood 4 can be adjusted according to the specific heat generated at the fan hood 4 through the closing component.

[0028] Furthermore, the closing assembly includes a second sealing plate 404 slidably installed inside the air intake hood 402. A second push rod motor 405 is fixedly installed on the air intake hood 402, and the output shaft of the second push rod motor 405 is fixedly connected to the second sealing plate 404. The second push rod motor 405 can drive the second sealing plate 404 to move up and down, thereby blocking the air inlet slot 403 and controlling the amount of air entering the air inlet slot 403.

[0029] The cabinet 1 is equipped with a lifting mechanism that drives the fan shroud 4 to slide up and down within the air intake slot 101. The lifting mechanism includes a motor 5 fixedly installed within the cabinet 1, and a lead screw 501 rotatably mounted within the air intake slot 101. The lead screw 501 is threadedly connected to the fan shroud 4, and one end of the lead screw 501 is coaxially and fixedly connected to the output shaft of the motor 5. The motor 5 drives the lead screw 501 to rotate, which in turn causes the fan shroud 4 to move up and down, thus adjusting the fan shroud 4 to a position within the cabinet 1 where heat generation is highest.

[0030] The working principle of this embodiment is as follows: When cold air enters the inside of the cold air pipe 2, it will enter the inside of the air intake slot 101 through the air inlet 104. The cold air entering the air intake slot 101 will enter the exhaust slot 102 through the flow chamber 601, so that the cold air can come into contact with the server 6, thereby exchanging heat between the cold air and the server 6 to achieve the purpose of dissipating heat from the server 6. Subsequently, the heated gas will enter the heating pipe 201.

[0031] The first push rod motor 3 pushes the first sealing plate 301 to move, which can block the air inlet 104. This changes the size of the air inlet 104 and controls the size of the air inlets 104 on multiple cabinets 1. Based on the size relationship of the air inlets 104 on different cabinets 1, the amount of air entering different cabinets 1 can be controlled to be different while keeping the output power of the fan device constant. Therefore, the cold air can be reasonably distributed according to the heat dissipation required by different cabinets 1 in the current working environment.

[0032] The second push rod motor 405 can drive the second sealing plate 404 to move up and down, thereby blocking the air inlet slot 403 and controlling the amount of air entering the air inlet slot 403.

[0033] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
