Description

Airflow guide floor with dip protection

technical field

The invention relates to a floor, in particular to an airflow guiding floor with angle protection.

Background technique

The machine room usually adopts the form of air supply under the floor to carry out air supply and cooling to the server and the equipment in the machine room. The vents of the ventilation floor are generally arranged flush with the static floor, the floor needs to be overhead, and the lower space is used as arranging ventilation pipes or directly as ventilation. In the static pressure box, the cold air enters the computer room through the vents on the ventilated floor, exchanges heat with the heat generated by the servers and equipment, and then is discharged from the air outlet on the upper part of the computer room. Ventilated floors currently on the market are only for transporting cold air from under the floor to the floor, never considering the ventilation efficiency and the cooling efficiency of heating equipment, and they are not oriented. 50%-70% of the air volume of the tuyere is mixed with the hot air discharged from the cabinet, and directly returns to the precision air conditioner, and a small part is sucked into the cabinet, which cannot meet the needs of customers. In addition, the ventilation floor opening rate of the existing data center is low, ranging from 20% to 55%, and the air supply volume is 1500-2500 cubic meters per hour.

Detailed ways

The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

As shown in Figure 1, the airflow guide floor with inclination angle protection of the present invention includes a first beam 1, a second beam 2, a first longitudinal beam 3, a second longitudinal beam 4, a third longitudinal beam 5, a fourth longitudinal beam 6, The panel 7, the first grid 8, the second grid 9, the first beam 1 and the second beam 2 are parallel to each other, the first longitudinal beam 3, the second longitudinal beam 4, the third longitudinal beam 5, and the fourth longitudinal beam 6 Parallel to each other, the first beam 1, the second beam 2 and the first longitudinal beam 3, the second longitudinal beam 4, the third longitudinal beam 5, and the fourth longitudinal beam 6 are vertically staggered, and the panel 7 is located above the fourth longitudinal beam 6, The first grille 8 and the second grille 9 are located between the first beam 1, the second beam 2 and the first longitudinal beam 3, the second longitudinal beam 4, the third longitudinal beam 5, and the fourth longitudinal beam 6, the first The inclination angle of the grid 8 and the inclination angle of the second grid 9 are fifty degrees to eighty degrees. When the inclination angle of the first grille 8 and the inclination angle of the second grille 9 are 70 degrees, the optimal design of the heating equipment to achieve the maximum air supply rate can be obtained by computational fluid dynamics (CFD) optimization design.

The first beam, the second beam, the first longitudinal beam, the second longitudinal beam, the third longitudinal beam, and the fourth longitudinal beam are the main load-bearing members, the first grid and the second grid are the secondary load-bearing members, and the panels are connected Forced members of frames and gratings. The upper end of the airflow guide floor with inclination protection is flattened and flush with the panel, which is convenient for the walking of the staff and the handling of the equipment. The lower end of the airflow guide floor with angle protection is vertical to facilitate tight connection with the card slot of the main support member, and facilitates assembly.

The present invention is mainly applied in data center computer rooms or buildings with similar functions. The working principle of the present invention is as follows: each vertical diffuser of the airflow guide floor with inclination protection has a 70-degree inclination angle at the top to guide the air supply into the server cabinet, so that the entire airflow guide floor with inclination protection can send out the air volume 90% is blown directly to the cabinet, and the remaining 10% is mixed with the hot air discharged from the cabinet, and then returned to the precision air conditioner. If the cabinet is evenly divided into upper, middle and lower sections, the air supply will be evenly distributed in the three areas, which are about 28%, 34%, and 31% respectively. The air-guiding floor with angled protection precisely directs the supply air to the surface of the cabinet to reduce supply air bypass. In this way, new projects can reduce the number of precision air conditioners used in the computer room, and renovation projects can set some non-inverter precision air conditioners to standby mode or adjust the speed of the inverter fan to provide a relatively low static pressure value to save energy. With the increase of supply air acquisition rate, the total air supply volume required to cool the computer room of the same size will be significantly reduced. total

The reduction of the air supply volume has a huge impact on the reduction of the energy consumption of the air supply fans required in the data center computer room. In addition, the reduction of energy consumption can also avoid many inconveniences caused by adding cold pools in the data center, such as fire protection changes, wiring restrictions, and reduced flexibility.

Various modifications and changes can be made to the present invention by those skilled in the art. Thus, the present invention covers the modifications and changes that come within the scope of the appended claims and their equivalents.
