The utility model has the advantages that: accomplish the standby of low-temperature receiver by increasing the chilled water total amount, only need the bigger water tank of series connection volume on the chilled water loop, the cold of having substituted the bad for the good in service at ordinary times, charge reserve and be used in (maintenance constant temperature is cooling not) in the system, in case be in an emergency, only need to start chilled water pump and get final product cooling, guaranteed the security of data center.This system is simple and economical and practical, drop into little and effect obviously, reliable.Make full use of the cold of main frame simultaneously, removed the input of backup host from.
Description of drawings
Accompanying drawing 1 is an existing conventional cold supply system structural representation;
Accompanying drawing 2 is a cold supply system structural representation of the present utility model.
Embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-2, mark 1-16 is respectively among the figure: cooling water circulating pump 1, handpiece Water Chilling Units 2, user side 3, heat radiation water circulating pump 4, cooling tower 5, water tank 6, dividing plate 7, heat-insulation layer 8, water charging system 9, water pipe 10, small pump 11, buffer tank 12, vacuum degassing machine 13, high flow rate spiral dirt separator 14, chilled water chemicals dosing plant 15, chilled water chemicals dosing plant 16.
Referring to Fig. 1, this is the cold supply system structure of a routine, mainly comprise: the cooling loop, form by cooling water circulating pump 1, handpiece Water Chilling Units 2 secondary sides, user side 3, water charging system 9, chilled water chemicals dosing plant 16 and the high flow rate spiral dirt separator 14 of series connection setting successively; The heat radiation loop is made up of heat radiation water circulating pump 4, handpiece Water Chilling Units 2 primary sides, high flow rate spiral dirt separator 14, chilled water chemicals dosing plant 15 and cooling tower 5 that series connection is provided with.
Wherein, water charging system 9 is used for the water yield to cooling loop replenish lost.It is communicated with water pipe 10, drive from water pipe 10 water intakings by small pump 11, handle to the water delivery of cooling loop through buffer tank 12, vacuum degassing machine 13, this is the industry technology of commonly seeing, do not repeat them here, small pump 11, buffer tank 12 and vacuum degassing machine 13 do not indicate in the drawings simultaneously.
High flow rate spiral dirt separator 14 is used for removing the new water that water charging system 9 is replenished in pipeline recirculated water interior dirt, especially the cooling loop, and the alluvial dirt causes line clogging or corruption in two circulation waterways to avoid.16 of chilled water chemicals dosing plants 15, chilled water chemicals dosing plant be the drug component of replenish lost in two closed circuits respectively.
Referring to Fig. 2, technical scheme and above-mentioned conventional cold supply system difference are as follows in the utility model:
Be connected in series with two water tanks 6 between handpiece Water Chilling Units 2 and the user side 3, and on a by-pass pipe road in parallel, the two ends of two water tanks 6.Wherein arbitrary water tank 6 external packets are covered with heat-insulation layer 8, to play the effect that insulation reduces energy loss.Water tank 6 is inner parallel, be staggeredly equipped with some dividing plates 7 with circuitous water route of formation water tank 6 in, current are advanced along the water route that dividing plate 7 is separated in water tank 6, the cold water (hot water) of coming in extrudes hot water (cold water) and goes on one side, water outlet and water inlet can not mix water, guarantee the stable of water supply.
More than describe the structure of above-mentioned cold supply system in detail, describe the principle of work of cold supply system described in the utility model below in conjunction with said structure in detail:
Handpiece Water Chilling Units 2 is sent into water tank 6 with the backwater cooling back of terminal high temperature by cooling water circulating pump 1 during first the operation, and the water in the water tank 6 is forced out gradually, and the water in water tank 6 all becomes cold water.Water tank 6 operations capable of bypass of system's this moment, the water tank 6 that is full of cold water is stored on one side as standby low-temperature receiver; Also can continue by water tank 6 operations, cryogenic freezing water is sent into end after only flowing through water tank 6.When system's low-temperature receiver or conventional electric power are out of order, emergency power pack is devoted oneself to work, guarantee less cooling water circulating pump 1 continuous service of power consumption, the cold water of the huge scale of construction is brought into play standby low-temperature receiver effect in the water tank 6 at this moment, guarantees to keep end is carried out cooling in a few hours.
Though below design and embodiment according to the utility model purpose are described in detail with reference to accompanying drawing, but those of ordinary skills can recognize, under the precondition that does not break away from the claim limited range, still can make various improvement and conversion to the utility model, as: water tank adopts the dividing plate mode to guarantee that even, the cold and hot layering of current does not mix water, also can adopt similar equivalent structure to substitute in actual applications, such as be provided with water-locator etc. in the water tank.
