Problems solved by technology
If a cold storage pool is used for cold storage, in order to prevent the frozen return water from flowing back, a heat exchanger must be used for heat exchange, because the instantaneous cooling capacity is large in the event of a redundant disaster, and the requirements for the heat exchanger are high, resulting in a large cost investment; On the one hand, from the perspective of redundancy efficiency, the use of heat exchangers for heat exchange will cause temperature gradient loss, and the corresponding redundancy system is relatively complex, with a high failure risk rate
Moreover, the construction of the above two types of cold storage devices has a greater impact on the construction site of the completed data center

The invention discloses a pressurized emergency cooling device, which includes a tank body, an upper water distributor on the upper part of the tank body is provided with an upper diffuser and an upper water distribution pipe, and the upper water distribution pipe is connected to the refrigeration unit through a hot water pipe. The water return pipe is connected, and the lower water distributor at the bottom of the tank is provided with a lower diffuser and a lower water distribution pipe, and the lower water distribution pipe is connected with the frozen water outlet pipe through a cold water pipe; The water flow directions of the chilled water or hot water in the upper diffuser, the upper water distribution pipe, the lower diffuser and the lower water distribution pipe are different. The effective combination of the tank body with the upper water distributor and the lower water distributor means that by changing the water flow direction of the upper diffuser, the upper water distribution pipe, the lower diffuser and the lower water distribution pipe, it can realize cold storage or cooling. It does not need to rely on the size characteristics of the tank to realize cold storage and cooling, the ratio of height to diameter is reasonable, and there is no need to use plate heat exchangers for heat exchange, which leads to low cost and high disaster safety.
Description
technical field [0001] The invention relates to a cold storage device, in particular to a pressurized emergency cold supply device. Background technique [0002] At present, there are mainly two types of redundant cold storage devices used in data centers: open atmospheric pressure water tanks for cold storage and cold storage pools. If an open atmospheric pressure water tank is used for cold storage, in order to prevent the backflow of chilled water, the height of the open atmospheric pressure water tank must be greater than the height of the highest cooling point of the machine building. The height of the cooling point of the general data center is between 20-30 meters, and the volume of the cold storage device used for the redundancy of each data center will not exceed 600m 3 , so the height-to-diameter ratio of open atmospheric tanks is close to 4:1, which greatly increases the difficulty and risk of construction, and due to crustal movement, typhoon and other issues, t...
