Heat dissipation device capable of adaptively controlling air volume and control method thereof

Abstract

The invention provides a heat dissipation device capable of adaptively controlling air volume and a control method thereof. The adopted scheme is as follows: the device comprises a plurality of branchair duct pipes which are integrated with a cabinet, and a main air inlet pipe and a main air outlet pipe which are arranged on the cabinet; a temperature sensor is mounted at an air outlet of the branch air duct pipe; a temperature sensor and an electric valve mechanism are mounted at an air inlet of the branch air duct pipe; a heat dissipation unit independently controlled by a server mainboardor a fan board is upgraded into centralized heat dissipation controlled by a cabinet outside a system; the self-adaptive heat dissipation of each server node is realized by automatically adjusting theair inlet amount of each server node, and the opening and closing degree of the channel at the air inlet of the branch air duct pipe is realized through the electric valve mechanism, so that the amount of introduced cold air is controllable, the on-demand distribution and intelligent control are realized, the cost is reduced, and the maintenance difficulty is reduced.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a cooling device for adaptively controlling air volume and a control method thereof. Background technique [0002] Most of the existing server chassis use air-cooled independent heat dissipation. The current heat dissipation design has the following disadvantages: 1. The maintainability experience of the whole machine is poor; 2. In order to match the whole machine with different models and configurations, additional boards need to be designed , and configure a corresponding set of heat dissipation strategies, which increases the difficulty of design; 3. Each complete machine needs to be equipped with a fan board and a corresponding fan, which increases the cost; The high speed is often accompanied by a lot of noise, which will cause certain difficulties for maintenance personnel. Based on the above shortcomings, the demand for centralized heat dissipation is becom...

[0002] Most of the existing server chassis use air-cooled independent heat dissipation. The current heat dissipation design has the following disadvantages: 1. The maintainability experience of the whole machine is poor; 2. In order to match the whole machine with different models and configurations, additional boards need to be designed , and configure a corresponding set of heat dissipation strategies, which increases the difficulty of design; 3. Each complete machine needs to be equipped with a fan board and a corresponding fan, which increases the cost; The high speed is often accompanied by a lot of noise, which will cause certain difficulties for maintenance personnel

[0005] The above-mentioned heat dissipation system is a centralized heat dissipation system for the computer room, and the centralized heat dissipation of each cabinet still has the following disadvantages: 1. It is the size of the air inlet of the cabinet that is adjusted instead of automatically adjusting the air volume for each server node; 2. Using sliding fans 3. The temperature sensor is only placed at the adjustment device of the air inlet, which is not very useful for the heat dissipation inside the cabinet; 4. The design of the air hole can block the cold wind The disadvantages are not conducive to heat dissipation; 5. There is no system-level control circuit, and the control logic inside the intelligent electric control box is not clear
