2N, is equipped with two small oil circulating pumps in the oil inlet of each plate type heat exchanger, so not only wastes space, also add into
This, reduces reliability.Present oil circulating pump is all to carry out concentrated controling management, and oil is equipped with the oil inlet of each Oil Tank
Regulating valve, the temperature fed back according to each Oil Tank carries out Flow-rate adjustment distribution.Arrived by the returning-oil temperature sensor feedback in cabinet
The information of automatic control equipment carries out Flow-rate adjustment, when temperature is higher than design temperature, and the aperture increase of regulating valve increases the circulation of oil
Amount；When temperature is less than setting value, the aperture of regulating valve reduces.Y-type filter is housed before the entrance of oil circulating pump simultaneously, it is made
With the filtering for impurity.
There is no cooling tower device, compressor, fan, refrigerant in the residual neat recovering system of liquid cold data center.Water is followed simultaneously
Ring pump and oil circulating pump have also all carried out concentrated controling management, use N+1 redundant mode.Therefore the system is without compression
Machine, the pollution of fan noise, while improving space availability ratio and reducing input cost, improves the efficiency of heat transfer,
The reliability of system is improved, the loss of the energy is reduced.
And liquid cold data center residual neat recovering system use conduction oil directly with server heat exchange, then pass through
Plate type heat exchanger transfers heat to waste-heat recovery device, and the heat exchange pattern directly contacted substantially increases heat exchange efficiency.Work
When there was only the participation of conduction oil, oil circulating pump, water-circulating pump, different from that must have consumable accessory pressure in patent CN103249284A
Contracting machine and consumable accessory fan, pump, refrigerant.
The system is for difficult, the problem of heat recovery rate is low that solve data center heat recovery.
Traditional liquid cold data center, each cold main frame of liquid is equipped with the small-sized water-circulating pump of a preparation and a use and small-sized oil circulation
Pump, and the cold main frame of currently all liquid all only shares one or two big water-circulating pump, big oil circulating pump.Water-carrying capacity and oily flow
Regulation is all managed concentratedly and centralized Control, uses N+1 redundant modes；Simultaneously equipped with heat reclaim unit, fully return
Receive the waste heat of computer room.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
