Pressure ventilation system capable of regulating and controlling airflow distribution

Abstract

The present invention provides a pressure ventilation system capable of regulating and controllingairflow distribution, cold air circulates in the cold air main channel, and the cold air enters the server for heat exchange and then enters the hot air main channel; the airflow adjusting plate is arranged in the cold air main channel and can rotate within the range between the direction that the plate face is parallel to the airflow and the direction that the plate face is perpendicular to the airflow, when the airflow adjusting plate is parallel to the airflow, normal flowing of the airflow is basically not affected, and the airflow keeps the original motion state; and when the temperature of a certain server reaches a set threshold value, the controller controls the airflow adjusting plate to rotate, airflow is blocked and guided, and the flow of airflow entering the corresponding cold air outlet is increased, so that the corresponding server obtains more cold air. Through mutual cooperation of the airflow adjusting plates, local airflow can be blocked, a certain server obtains more airflow, cold air is redistributed under the condition that the power consumption of an air conditioner is not increased, and local high temperature is avoided.

Description

technical field [0001] The invention relates to the field of data center heat dissipation, and further relates to a pressure ventilation system with adjustable airflow distribution. Background technique [0002] Data Center (Data Center) is a network of specific equipment for global collaboration, which is used to transmit, accelerate, display, calculate, and store data information on the Internet network infrastructure. The rapid development of Internet technology has led to the rapid rise of data centers in all corners of the world. Data centers have a large number of devices and need to ensure good heat dissipation efficiency. Data centers are typically cooled using an air conditioner (CRAC), which exhausts cool air from its outlet, circulates the data center and draws in hot air from its inlet. [0003] In order to ensure heat dissipation efficiency, existing data centers are often in a state of overall excess of cold air, that is, the overall amount of cold air exceeds...

Problems solved by technology

When the air flows in the corresponding channel, it is disturbed by cables and other structures to form turbulent flow, and the Venturi effect occurs. The static pressure and dynamic pressure of the airflow become unstable in the constant change, resulting in uneven distribution of cold air, and even The local temperature is too high; if a certain point is detected to be too high, it is necessary to increase the power of the air conditioner as a whole to output more cold air, but this will cause the original temperature to receive too much cold air, resulting in data loss. Central cooling utilization characteristics are poor, resulting in waste of energy
