Abstract
The utility model relates to a data center cross-flow cooling tower air wall air inlet system which comprises a cross-flow cooling tower body, a cross-flow cooling tower air wall fan, a cross-flow cooling tower filler, a cross-flow cooling tower fan, a cross-flow cooling tower water inlet pipe, a cross-flow cooling tower water distributor and a cross-flow cooling tower water collecting tank. The device is characterized in that the air inlet of the cross flow cooling tower is regulated in real time by regulating the air wall fan of the cross flow cooling tower, so that the air inlet is uniform and short circuit is prevented.

The outdoor air exchanges heat with the spray water (direct heat exchange, evaporation heat exchange, etc.), thereby reducing the temperature of the cooling water. Meanwhile, the air wall fan of the cross flow cooling tower consists of a plurality of fans, and when part of fans are in failure, the whole use of the cross flow cooling tower is not affected.
Description
Technical Field
The utility model relates to the technical field of a cross-flow cooling tower of a data center, and mainly relates to a cross-flow cooling tower air wall air inlet system.
Background
Today, information technology is very new, and cloud computing and data centers are vigorously developed in the context of new infrastructure. Aiming at a data center which runs continuously for 7x24 hours, the working efficiency of the cross flow cooling tower of the water cooling system is higher.
The conventional cross-flow cooling tower is characterized in that cooling water is sprayed downwards from the upper parts of two sides of the cross-flow cooling tower through a cross-flow cooling tower water distributor, cooling tower air inlet is inwards (from two sides to the middle) from the outer side of the cross-flow cooling tower, and cooling tower air inlet achieves the purpose of transverse flow (cross-flow), so that the purposes of heat exchange (direct heat exchange and evaporation heat exchange) between the cooling water and the cooling tower air inlet and cooling water are achieved.
According to the characteristics of the data center, the data center operates under partial load most of the time. Similarly, when the cross flow cooling tower is operated under partial load and partial air quantity, most of air inlet of the cross flow cooling tower enters from the upper part of the cross flow cooling tower, so that less air or no air is generated at the lower part of the cross flow cooling tower, and the heat exchange between cooling water and cooling tower air inlet is insufficient and the efficiency of the cooling tower is reduced. The reduction of the equipment efficiency causes the increase of energy consumption, and is unfavorable for the achievement of low-carbon targets in fourteen-five planning aiming at the data center of a large power consumption user.
Meanwhile, the cross flow cooling tower fan is used as an electric component of the cross flow cooling tower, has high failure rate, and once the fan fails, the whole cross flow cooling tower cannot normally operate. The equipment failure can bring hidden trouble to the safe operation of the data center.
Disclosure of Invention
The utility model aims to overcome the defects, and provides a data center cross flow type cooling tower air wall air inlet system which can ensure the constancy of the air inlet wind speed of all parts of a cross flow type cooling tower through the integral adjustment of a cross flow type cooling tower air wall fan. The air wall formed by combining the air wall fans of the cross flow type cooling tower is used for adjusting the air inlet of the cooling tower in a flow equalizing manner, so that the short circuit of the air inlet of the cooling tower is avoided, and the heat exchange of the cooling tower is insufficient and the efficiency is reduced.
Meanwhile, the 'wind wall' is formed by combining a plurality of cross flow cooling tower wind wall fans, when the cross flow cooling tower fans are in failure and part (single or a plurality of) cross flow cooling tower wind wall fans are in failure, the rest fans can still be normally used, so that the safety and reliability of the equipment are improved.

The cross flow cooling tower body belongs to the structural main body of the circulating spraying system of the cooling tower.
The cross flow cooling tower air wall fans are arranged on two sides of the cross flow cooling tower and at the air inlet of the cooling tower.
The cross flow type cooling tower filler is arranged at two sides of the cross flow type cooling tower (the inner side of the air wall fan) and below the water distributor of the cross flow type cooling tower.
The cross flow cooling tower fan is arranged in the middle of the cross flow cooling tower and above the cross flow cooling tower.
The water inlet pipe of the cross flow cooling tower is arranged on two sides of the cross flow cooling tower and above the water distributor of the cross flow cooling tower.

The system operation comprises the following steps:
1) When the cross flow cooling tower is in normal operation, the fan of the cross flow cooling tower is full power (100 percent of air quantity)
When the fan is in operation, the fan of the cross flow cooling tower outputs an electric signal and controls the fan of the air wall of the cross flow cooling tower to operate at full power (100 percent of air quantity);
2) Air inlet of the cross flow cooling tower enters the filling of the cross flow cooling tower through cross flow cooling tower air wall fans arranged on two sides of the cross flow cooling tower. After the air inlet of the cooling tower exchanges heat with spray water in the filling material of the cross-flow cooling tower (direct heat exchange and evaporation heat exchange), the spray water is discharged to the outside of the tower body through a cross-flow cooling tower fan at the upper part of the cross-flow cooling tower;
3) When the partial load (such as 50% load) of the cross flow cooling tower is running, the partial air quantity (50%) of the fan of the cross flow cooling tower is running, the fan of the cross flow cooling tower outputs an electric signal, and the partial air quantity (50%) of the fan of the air wall of the cross flow cooling tower is controlled to run in a linkage manner;
4) When the cross flow cooling tower fan fails (such as a fan motor is short-circuited and the fan stops running), the cross flow cooling tower air wall fan enters a failure mode and runs at full power (100% of air quantity) so as to ensure the normal use of the cross flow cooling tower;
5) The cross flow cooling tower air wall fans are arranged on two sides (air inlet sides) of the cross flow cooling tower, and are used for carrying out 'flow equalization' adjustment on the air inlet of the cooling tower, so that the air inlet of the cooling tower with partial air quantity is ensured to fully contact with the cooling tower filler during partial load and fully exchange heat with 'cooling water' sprayed by the water distributor of the cross flow cooling tower; the air inlet short circuit of the cross flow cooling tower (more air quantity at the upper part of the filler and less air quantity at the lower part of the filler or even no air) is avoided when partial air quantity is generated, so that the air inlet of the cooling tower and cooling water are fully exchanged, and the operation efficiency of the cross flow cooling tower is improved;
compared with the prior art, the method has the following characteristics:
1) The heat exchange efficiency is remarkably improved.
The conventional cross flow cooling tower sprays cooling water backwater (high temperature cooling water) onto the cross flow cooling tower filler through a cross flow cooling tower water distributor arranged at the upper part of the cooling tower, and the cooling water exchanges heat (air-water) with cooling tower air inlet (from outside to inside) under the action of gravity (from top to bottom) and in the process of flowing to a cross flow cooling tower water collecting tank.
According to the utility model, through the air wall fan of the cross flow type cooling tower, the air inlet of the cooling tower is subjected to uniform flow, so that the short circuit of the air inlet of the cooling tower is effectively avoided when the cross flow type cooling tower is used for partial load and partial air quantity, the air-water is fully subjected to heat exchange, the partial load heat exchange time is prolonged, and the efficiency of the cross flow type cooling tower is improved.
2) The reliability of the equipment is greatly improved
The conventional cross-flow cooling tower is characterized in that the cooling tower is subjected to air intake by a cross-flow cooling tower fan arranged at the middle upper part of the cooling tower, and the air is discharged outside the cross-flow cooling tower after heat exchange with cooling water through the filler of the cross-flow cooling tower at two sides of the cross-flow cooling tower. Once the cross-flow cooling tower fan fails, the cross-flow cooling tower will not operate properly.
The utility model combines a plurality of cross flow cooling tower air wall fans into an 'air wall', and can still ensure the normal operation of the cross flow cooling tower when the cross flow cooling tower fan fails (such as a short circuit of a fan motor, a fan stalls) or part (single or a plurality of) of the air wall fans fail.
The 'wind wall' formed by a plurality of fans clearly improves the risk resistance of the cross-flow cooling tower greatly and improves the equipment reliability greatly.
