The invention discloses a pressure-bearing emergency cooling device which comprises a tank body, wherein an upper flow diffuser and an upper water diversion pipe are arranged on an upper water distributor at the upper part of the tank body; the upper water diversion pipe is communicated with a freeze water returning pipeline through a hot water pipeline; a lower flow diffuser and a lower water diversion pipe are arranged on a lower water distributor at the lower part of the tank body; the lower water diversion pipe is communicated with a freeze water discharging pipeline through a cold water pipeline; during cold accumulation or chilling, directions of freeze water flows or hot water flows on the upper flow diffuser, the upper water diversion pipe, the lower flow distributor and the lower water diversion pipe are different; and the tank body is effectively combined with the upper water distributor and the lower water distributor, that is, water flow directions of the upper flow diffuser, the upper water diversion pipe, the lower flow diffuser and the lower water diversion pipe are changed, and the cold accumulation or the chilling is realized. The cold accumulation and the chilling are realized without depending on the size characteristic of the tank body, the height-diameter proportion is reasonable, a plate heat exchanger is not required for heat exchange, the cost is low, and the disaster recovery safety is high.
Description
Technical field
The present invention relates to a kind of cold-storage device, refer in particular to the emergent cooling apparatus of a kind of pressure-bearing.
Background technology
For the superfluous calamity cold-storage device of data center, mainly contain open type normal pressure water pot at present and carry out two kinds of cold-storage and water storage pools etc.If adopt open type normal pressure water pot to carry out cold-storage, for preventing that chilled water backwater from flowing backwards, necessarily require open type water at atmospheric pressure tank height to be greater than machine building the highest for cold spot height.The volume for cold spot height superfluous calamity of ，Er Ge data center between 20-30 rice cold-storage device used at general data center can not surpass 600m
3, so the ratio of height to diameter of open type normal pressure water pot approaches 4:1, greatly increased difficulty of construction and construction risk, and due to problems such as crustal movement, typhoons, the risk of the long-term operation of such water pot is very high.If adopt water storage pool to carry out cold-storage, in order to prevent that freezing backwater from flowing backwards, must use heat exchanger to carry out heat exchange, because the instantaneous amount of letting cool is very large during superfluous calamity, having relatively high expectations of heat exchanger, causes cost investment larger; On the other hand, from the angle of superfluous calamity efficiency, consider, use heat exchanger to carry out heat exchange meeting and have thermograde loss, and corresponding disaster tolerant system is comparatively complicated, failure risk rate is high.And, for the above-mentioned two kinds of cold-storage device construction of built data center, receive site influence larger.
Summary of the invention
Based on this, the invention reside in the defect that overcomes prior art, provide a kind of safe, and the low emergent cooling apparatus of pressure-bearing of cost.
