Problems solved by technology

However, in the existing server cooling solutions, only the cooling effect on the server is paid attention to, and the power consumption of the fan cooling is not paid attention to.
Therefore, the existing fan cooling scheme makes the power consumption of the fan too large

Embodiment Construction

[0043] In order to avoid damage to the server due to excessive temperature of the server in the computer room, when cooling the server in the computer room, the temperature of the server in the computer room during operation is usually reduced by using the fan as the main cooling method and the air conditioner as the auxiliary method. Therefore, a fan with high power consumption is used to dissipate heat from the server.

[0044]The inventor found through research that in the existing technical solutions, the fans are usually mechanically controlled to rise and fall at the same speed, that is, when the fan speed needs to be increased, the speed of all fans will be increased at the same time, and when the fan speed needs to be reduced , will reduce the speed of all fans at the same time. However, in practical applications, fans are deployed at different positions, and the fans at different positions have different heat dissipation effects on different servers. This makes it pos...

Abstract

The invention discloses a control method and device for a rotational speed of a fan. The control method for the rotational speed of the fan comprises the following steps: obtaining a first temperatureand a second temperature, and / or, obtaining a first distance and a second distance; obtaining a standard rotational speed of the target fan; determining a first rotational speed weight value of the target fan relative to a first server according to the obtained first temperature and / or first distance, and determining a second rotational speed weight value of the target fan relative to a second server according to the obtained second temperature and / or second distance; and calculating a target rotational speed of the target fan on the basis of the standard rotational speed of the target fan, the first rotational speed weight value and the second rotational speed weight value, so as to control the target fan to run at the target rotational speed. Thus, different fans are enabled to realizeheat dissipation for the servers on the basis of different rotational speeds by controlling the rotational speed weight values, so that the effect of reducing the power consumption of the fan while ensuring the heat dissipation effect on the servers.

Description

technical field [0001] The present application relates to the technical field of fan control, in particular to a method and device for controlling fan speed. Background technique [0002] With the development of Internet technology, more and more servers need to perform a large amount of data calculation and data storage to support various services provided by the Internet. And these servers are usually in a 24-hour uninterrupted high-speed operation state, and the heat generated by it is a problem that needs to be paid attention to. [0003] At present, it is generally adopted to cool down multiple high-power servers in the computer room by using fans as the main cooling method and air-conditioning as a supplementary cooling method. However, in the existing server heat dissipation scheme, only the heat dissipation effect on the server is paid attention to, and the power consumption during the heat dissipation of the fan is not paid attention to. Therefore, the existing so...
