Description

A centralized cabinet heat dissipation method

technical field

The invention relates to the field of heat dissipation of a server cabinet system, in particular to a centralized heat dissipation method for a cabinet.

Background technique

The rapid development of the Internet has resulted in explosive growth of information resources. People use the Internet as a media, and their demand for information is also increasing. Various large-scale data computer rooms have also emerged as the times require. The number of individuals—servers and storage cabinets—that make up a data center is also increasing. As the amount of information increases, more cabinets cannot be deployed in the original computer room. Therefore, compressing the space occupied by a single CPU and deploying more CPUs has become a development trend. Therefore, the 1U server has become a key application model, but the space of the 1U server limits the size of the cooling fan. The fan generally uses a 40mm×40mm fan, and the efficiency of a small fan is much lower than that of a large fan, resulting in a huge waste of energy consumption. .

Contents of the invention

The purpose of the present invention is to provide a centralized cooling method for cabinets.

The purpose of the present invention is achieved in the following manner, and the design steps are as follows:

1) A thermal insulation layer is added outside the centralized server cabinet, and the interior is divided into multiple corridor-style cooling channels with thermal insulation partitions. The server equipment is placed in the node fixing frame of the cooling channel, and nodes with similar cooling requirements are placed in a In the frame, a fan wall with a large cooling fan is installed at one end of each cooling channel, and the small cooling fan in each server device is removed;

2) According to the different heat dissipation requirements of server equipment, different power cooling fans are configured in the cooling air duct to reduce energy waste;

3) Set the hard disk storage device of the server at the air inlet end of the heat dissipation channel, away from the fan to reduce the impact of fan vibration on the hard disk.

The beneficial effect of the present invention is that, based on the characteristic that the large-size fan has better performance than the small-size fan, the efficiency of the heat dissipation system is improved, the energy consumption of heat dissipation is reduced, and the limitation of the installation of the fan in the narrow space of the server is avoided , to ensure fan redundancy and improve system reliability. The adjustable heat dissipation air duct design can ensure that nodes with different heat dissipation requirements are assigned to different heat dissipation air ducts to avoid excessive cooling. The independent air duct design can ensure that backflow is avoided when the cabinet is not fully configured. The position of the fan away from the hard disk also eliminates the impact of fan vibration on the hard disk, increasing the reliability of the system.

Description of drawings

Fig. 1 is a schematic structural diagram of a system using heat dissipation channels for centralized heat dissipation.

Detailed ways

The method of the present invention is described in detail below with reference to the accompanying drawings.

The structure of the present invention is different from the traditional cabinet cooling system structure in which the fan in the server in the cabinet is used as the cooling air flow providing device.

The structure of the present invention is to modify the back door of the traditional cabinet that only provides vents into a heat dissipation channel with a heat insulating wall inside, and a fan wall is arranged at the end of the heat dissipation channel, and a large fan is installed on the fan wall. And with the fan wall as the core, supplemented by node fixed frames and independent air duct structure, an independent heat dissipation system is formed.

The heat dissipation channel is the core of the system structure. According to the requirements, the cabinet is divided into several areas, and each area is responsible for providing air flow for a certain number of nodes.

The node fixing frame is mainly responsible for the installation and fixing of the node motherboard, and separates the node from the surrounding area.

The independent air duct structure is responsible for closing the area between the node fixing frame and the fan wall, and part of the structure of the frame can be adjusted to ensure that different numbers of nodes correspond to different numbers of fans as a whole.

As described in the summary of the invention, the system structure of the present invention mainly includes: the heat dissipation channels separated by the fan wall, forming each independent heat dissipation air channel structure. In this structure, we remove the fans from various servers and install them in the node fixed frame, and put the nodes with similar heat dissipation requirements in one frame.

Example

In a typical configuration environment, we can use 20 1U Gemini nodes as an independent air duct, occupying a 10U space, and install nine 120mm*38mm fans in the corresponding 10U space on the rear fan wall, and then apply the independent air duct The channel structure closes the area between the node frame and the fan wall, thus forming a small-scale overall cooling air channel, these nine fans provide air flow for 20 nodes, and each node must be equipped with at least 3 or more 40mm*56mm fan.

Compared with the traditional cabinet heat dissipation architecture, this new architecture has low cost, low energy consumption, high redundancy, and high reliability.

The low-cost implementation is described as follows: using nine 120×38 fans will save at least 60% of the cost compared to sixty 40×56 fans.

The implementation of low power consumption is as follows: the maximum power consumption of 9 120×38 fans will be about 50% of that of 60 40×56 fans.

The way to achieve high redundancy is as follows: Add fan anti-return structure to the fan wall to achieve 7+2 redundancy.

The implementation of high reliability is as follows: the fan wall and the node fixing frame are no longer tightly connected, and the vibration of the fan will no longer have any impact on the hard disk, which improves the reliability of the node.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
