Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.

As shown in Figure 1, fluorine pump Two-way Cycle handpiece Water Chilling Units cold accumulation system of the present utility model, mainly comprise: cold-storage heat-exchanger and the condensation heat pipe array being placed in external environment, described cold-storage heat-exchanger comprises the evaporation heat pipe array storing and have the airtight water tank of refrigerant He be located at airtight water tank inside, import and the outlet of described airtight water tank are connected in parallel by the cold water pipes of pipeline and handpiece Water Chilling Units, and by being located at being incorporated to of Valve controlling cold-storage heat-exchanger on pipeline, water tank is also connected with refrigerant surge tank and cushions refrigerant freezing and expansion simultaneously.Evaporation heat pipe array in described airtight water tank is as the evaporator section of heat pipe, and the steam (vapor) outlet at top is communicated with the condensation heat pipe array of external environment by evaporation tube; Described condensation heat pipe array is as the condensation segment of heat pipe, and bottom is connected to form circulation with evaporation heat pipe array again by liquid back pipe, described condensation heat pipe array is also furnished with spray washing and/or air-cooler cools, and condensation heat pipe array relative evaporation heat pipe array higher thus formed gravitational difference; Described evaporation heat pipe array and condensation heat pipe array vertically rearrange by multiple row spiral heat pipe, and two helical form heat pipes that often row spiral heat pipe is 3 ~ 8cm by internal diameter are entwined, and the inwall of spiral heat pipe is provided with wick layer.The stroke of helix tube is longer relative to straight tube, has larger heat exchange area and working medium capacity, especially when two-tube helically coiling arrange time, larger heat exchange area can be exchanged for less space.

When being in the higher environment of equitemperature in summer, environment cannot for cold-storage apparatus enough low-temperature receivers are provided time, in such scheme, fluorine pump double circulation cold-storage device can also be introduced, that is: refrigerated medium pump and the backflow of control valve pressure working fluid condenses liquid are set on the liquid back pipe of evaporation heat pipe array, simultaneously at the evaporation tube also refrigeration compressor in parallel (i.e. fluorine pump) of evaporation heat pipe array, this refrigeration compressor can be the various ways such as vortex, screw rod, centrifugal and magnetic suspension.When sudden load change, cold-storage water tank and wind handpiece Water Chilling Units are run simultaneously, improve unit refrigerating capacity; If when there is a part of generating units fault in multiple stage handpiece Water Chilling Units at scene, open cold-storage pattern released cold quantity, ensure that cold continues supply.

Cold accumulating pond cold-storage has double-mode: when utilizing outdoor cold source, preferably adopts fluorine pump circulation natural cold source type to carry out cold-storage; When outdoor natural cooling source cannot use, compressor mode is adopted to carry out cold-storage.When the cold storage cooling by wind of fluorine pump Two-way Cycle is used for data center, the security of data center can not only be improved, make data center when power-off or main process equipment fault time still have cold supply, decrease data center to delay the possibility of machine, outdoor low temperature environment can also be made full use of, under the pattern of natural cooling source, carry out cold-storage, reach energy-conservation effect.

In addition, the cold storage cold side of fluorine pump Two-way Cycle can be air-cooled, also can be a kind of type of cooling utilizing cooling water, when using cooling water as low-temperature receiver, not only can realize cool storage function, the function of lasting cooling can also be realized, because the power consumption of cooling tower is also little, still can ensure to run, when outdoor temperature is low by UPS, continue to provide cold by cooling tower cooling, improve data center security further.

In such scheme, refrigerant directly can adopt water, or adopts the calcium chloride water that latent heat is large.Preferably, the aqueous solution of 20% ~ 40% Disodium sulfate decahydrate and 15% ~ 25% sodium acetate trihydrate can also be contained, or contain the aqueous solution of 20% ~ 40% Disodium sulfate decahydrate and 15% ~ 30% calcium chloride, because the icing phase transition temperature of above-mentioned mixing refrigerant can reach 5 ~ 27 DEG C, thus temperature is higher again summer effectively can utilize ambient temperature by its latent heat of phase change, the spray washing cold wind function outside especially supporting condensation heat pipe effectively utilizes Environmental cold source.

Preferably, the outer wall at 1/2 ~ 2/3 position of the upper end of evaporation heat pipe array is smooth, and the outer wall at residue position is provided with ring fin.The spiral heat pipe adopting two strands to be wound around due to heat pipe in the utility model also to immerse in refrigerant heat absorption working medium is evaporated, and pipe range is at about 1m, evaporation endothermic Duan Guan top in this process, therefore first heat pipe outer wall freezes from middle and upper part, only the icing rate that ring fin is conducive to hypomere is set at hypomere and catches up with upper position, thus reach and evenly freeze.In addition, the more important thing is and make to keep more Large space between two of middle epimere strands of heat pipes, be beneficial to heat transfer.Further, the spacing of evaporating each heat pipe in heat pipe array and condensation heat pipe array is 8 ~ 30cm, preferred 15cm, thus under the prerequisite ensureing certain refrigeration density, prevents water tank completely icing.

Further, described spiral heat pipe adopts copper pipe, and the wick layer on inwall is porous foam layers of copper, has micropore capillarity and to be refluxed by working fluid condenses liquid absorptive collection efficiently evaporation endothermic again.Sodium chloride and electrolytic copper powder can be sintered under a shielding gas during production and form mesh-structured fine-celled foam layers of copper, be conducive to the backflow of condensed water.
