Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
The present invention discloses a kind of data center's afterheat generating system.As shown in Figure 1, data center's afterheat generating system packet
Include cold storage handpiece Water Chilling Units 1, freezing water pot 2, hot-water cylinder 3, heating device 4, heat-exchanger rig 5 and temperature difference electricity generation device.The temperature difference is sent out
Electric installation, there are that can generate electric current when the temperature difference, is used to use for power load 9, by data center between hot junction 7 and cold end 8
Cooling waste heat is converted into electric energy, turns waste into wealth.
Wherein, it is that hot junction 7 is arranged in heat to enable the method that the temperature difference is generated between the hot junction 7 of temperature difference electricity generation device and cold end 8
It (is heated with the high-temperature tempering heat exchange for flowing through cabinet assembly 6, heated again by heating device 4) in water pot 3, by stepped heating
Circulating hot water make hot junction 7 that higher temperature, cold end 8 be kept to be arranged in freezing water pot 2, (flowed through by the chilled water of cycle
The high-temperature tempering of cabinet assembly 6 cools down after heat exchange occurs in heat-exchanger rig 5, and the water after cooling is again through existing cooling refrigeration
Obtain meeting the requirements after the cooling of device the cooling water of temperature) keep cold end 8 to be in low-temperature condition.That is, circulate in hot-water cylinder 3
It is the water by heating twice, what is circulated in freezing water pot 2 is by cooling down twice from cold storage handpiece Water Chilling Units 1
Water, so remaining certain temperature difference between hot-water cylinder 3 and freezing water pot 2, temperature difference electricity generation device then utilizes this temperature difference to send out
Electricity.
In existing apparatus return water by after direct cooling refrigeration or natural cooling again cooling refrigeration to target temperature, energy consumption
It is high.The present invention is first to carry out a heat exchange after return water return, by a part of heat energy transfer to hot-water cylinder 3, is then dropped again
Temperature refrigeration makes full use of waste heat to target temperature, reduces consumption of data center；Temperature reduction refrigeration device enters coolant-temperature gage (from heat exchange
The water temperature that device 5 returns) and the temperature difference of the water outlet target temperature requirement temperature of water pot 2 (enter freeze) it is small, further reduced
Energy consumption.
The apopore of cold storage handpiece Water Chilling Units 1 is successively connected to freezing water pot 2 and cabinet assembly 6, backwater hole by pipeline
By the heat dissipation end of piping connection to cabinet assembly 6, cold water can also absorb machine except the cold end 8 for keeping temperature difference electricity generation device
The temperature of heat, reduction cabinet assembly 6 in cabinet component 6 is further that data center saves energy consumption.Heat-exchanger rig 5 is connected to
Cold storage handpiece Water Chilling Units 1, heat-exchanger rig 5 are preferably plate heat exchanger, the water drop for will heat up because flowing through cabinet assembly 6
Temperature, the temperature reduction refrigeration device reused in cold storage handpiece Water Chilling Units 1 further cool down, and comply with and again flow into freezing water pot 2
Temperature requirement.
Heating device 4 be too can positive heat collector, control device and transfer, control dress can be installed on positive heat collector very much
Transfer rotation can be controlled according to the variation of time by setting, to drive too can positive heat collector turn always towards the direction of the sun
It is dynamic.Too can positive heat collector convert the solar energy of collection to the thermal energy of water, so that the water temperature in hot-water cylinder 3 is increased.Hot-water cylinder 3 will be defeated
Enter periodically variable solar energy to store, be allowed to generate the heat of constant output, will not be fluctuated due to time change round the clock.
In order to avoid the heat in heat-exchanger rig 5 is wasted, in order to further increase the energy utilization rate of data center, change
Thermal 5 forms loop by piping connection to thermic load 10, heat-exchanger rig 5, thermic load 10 and hot-water cylinder 3 by piping connection
Structure, water can be flowed through thermic load 10 after positive heat collector heating very much in hot-water cylinder 3 by pipeline, and the water after heat release passes through pipeline
Heat-exchanger rig 5 is flowed back to, is exchanged heat again with the water in cold storage handpiece Water Chilling Units 1.
Thermic load 10 can be the various forms such as heating load or hot water load, when thermic load 10 is that hot water load etc. is open
When formula system, need at system user return pipe and (be provided with water replanishing device between thermic load 10 and heat-exchanger rig 5) into
Row moisturizing.
Because the hot junction 7 of temperature difference electricity generation device is arranged in hot-water cylinder 3, cold end 8 is arranged in freezing water pot 2, hot
Water pot 3 and freezing water pot 2 are inherently in close proximity, can even stick together.In order to avoid between freezing water pot 2 and hot-water cylinder 3
Heat transfer is provided with the thermal insulation layer made of heat-barrier material therebetween.
Cabinet assembly 6 includes multiple cabinets 61, and whole cabinets 61 are connected to cold storage handpiece Water Chilling Units 1 and freezing water pot side by side
Between 2.Cooling water is divided into a plurality of branch after flowing through freezing water pot 2, flows separately through each cabinet 61；Cooling water carries cabinet
61 heat returns to cold storage handpiece Water Chilling Units 1 after converging.
Power load 9 can be ventilation and air conditioning system or lighting device, can also be that accumulator etc. can store the dress of electric energy
It sets, reduces system comprehensive energy consumption, improve the energy utilization rate of data center.
Note that the technical principle that above are only presently preferred embodiments of the present invention and used.Those skilled in the art can manage
Solution, the present invention is not limited to specific embodiments described here, can carry out various apparent changes for a person skilled in the art
Change, readjust and substitutes without departing from protection scope of the present invention.Therefore, although by above example to the present invention into
It has gone and has been described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept,
