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 circulating spray system of the cross-flow cooling tower.
Background
Today, information technology is very new and different, and large data centers are developing at high speed in the context of new infrastructure. The data center runs continuously for 7x24 hours, and clearly puts higher demands on a cross-flow cooling tower (water-cooling system).
The conventional cross-flow cooling tower is characterized in that cooling water is sprayed downwards from the upper part of the cross-flow cooling tower, air inlet of the cooling tower is inwards (from two sides to the middle) from the outer side of the cross-flow cooling tower, air inlet of the cooling tower in the outer side inwards flows transversely (cross flow), downward cooling water exchanges heat with air inlet of the cooling tower in the inner side (direct heat exchange and evaporation heat exchange) to cool, and cooled cooling water is directly supplied to a water-cooling refrigerator for use.
In summer, especially in extreme weather of high temperature and high humidity, the humidity of the inlet air (outdoor air) of the cooling tower is high (the evaporation heat exchange efficiency is reduced), and the temperature difference between the inlet air and the cooling water of the conventional cross flow cooling tower is small (the direct heat exchange efficiency is reduced), so that the heat exchange capacity of the cross flow cooling tower is reduced and the heat exchange is insufficient. The cooling efficiency of the water-cooling refrigerator is reduced and the energy consumption is increased due to the rising of the outlet water temperature of the cooling water of the cross-flow cooling tower.

Meanwhile, water tank water is adopted for secondary spraying, so that the water resource utilization efficiency is improved, and the water resource is saved.
The purpose of the utility model is realized in the following way: the utility model provides a data center cross flow cooling tower circulation spray system, this system includes cross flow cooling tower body, cross flow cooling tower inlet tube, cross flow cooling tower water-locator, cross flow cooling tower filler, electron level gauge, cross flow cooling tower header tank, cross flow cooling tower air intake, cross flow cooling tower fan, circulation spray pump, filter, spray pipeline etc..

3) The cross flow cooling tower water distributor is arranged above the cross flow cooling tower filler and uniformly distributes (equalizes) cooling water conveyed from the cross flow cooling tower water collecting tank and sprays the cooling water to the cooling tower filler;
4) After being sprayed, the cooling water flows to a water collecting tank of the cross flow cooling tower along the filler of the cross flow cooling tower under the action of gravity.

2) Extreme weather adaptation capability increases significantly
