Background technology
Devaporizer mainly utilizes high-temperature gas system in absorption coil during the spray water section evaporation outside coil pipe at present The heat of cryogen and the refrigerant in pipe is gradually cooled to a kind of equipment of liquid by gaseous state.The operation of devaporizer is former Reason is shower water is transported to shower at the top of cooler by water pump by the water in water leg, through nozzle spray to condensation comb Outer surface forms very thin moisture film, is evaporated to vapor after the water heat absorption of part in moisture film, remaining falls into water leg, water supply pump circulation Use.Devaporizer has the advantages that system operation expense is low, initial cost is small and space-consuming is few, be widely used in base station, Computer room and large-scale data center etc..
But the cooling water of conventional devaporizer spray constantly heats up in cooling procedure, makes refrigerant condensing temperature far high In the temperature of spraying cooling water, i.e. air's wet bulb temperature, so as to which compressor power consumption increases, drop the efficiency of whole refrigeration system It is low.
The content of the invention
The purpose of this utility model is to provide a kind of transverse flow multistage devaporizer, devaporizer use multistage The mode of cooling, make to realize isothermal heat transfer between cooling water and refrigerant, it is cold to solve existing single-stage evaporation cooler refrigerant Solidifying temperature be higher than air's wet bulb temperature, the problem of making the reduction of whole system efficiency.
The utility model solves technical problem and adopted the following technical scheme that:
A kind of transverse flow multistage devaporizer, including first-class heat exchanger, one-level filler, secondary heat exchanger, two level filler, Three-level heat exchanger, three-level filler, blower fan, collecting-tank, water pump, shower, nozzle, cooling water, refrigerant;The first-class heat exchanger Input be refrigerant inlet, its output end is connected with the input of secondary heat exchanger;The input of the three-level heat exchanger It is connected with the output end of secondary heat exchanger, its output end is refrigerant outlet;The first-class heat exchanger, secondary heat exchanger, three-level Heat exchanger is connected by said sequence forms refrigerant circulation loop;The water pump input is connected with the output end of collecting-tank, its Output end is connected by shower with nozzle;The cooling water is transported to the shower at top from collecting-tank via water pump, through spray Mouth spray is carried out by first-class heat exchanger, one-level filler, secondary heat exchanger, two level filler, three-level heat exchanger, three-level filler respectively Collecting-tank is dripped back into after heat exchange, forms cooling water circulation loop;The side of the filler, which is placed, ensures that wind flows transversely through filler Blower fan.
Heat exchanger described above is pipe heat exchanger or plate type heat exchanger.
Blower fan described above is axial flow blower, is placed on the side of filler, and every grade of filler corresponds to one-level blower fan, i.e. blower fan number Amount is identical with filler quantity.
Blower fan described above is centrifugal blower, is placed on the side of filler, and the number of units of blower fan is determined according to air quantity.
Heat exchanger and filler described above are staggeredly placed, and one-level filler is placed in every grade of heat exchanger bottom.
Heat exchanger and filler described above can according to be actually needed do level Four and more than.
The devaporizer that the utility model provides, optimizes heat exchanger structure, and single-stage heat exchange is changed into multi-stage heat exchanger, made Stage-by-stage heat exchange between cooling water and refrigerant, greatly reduces heat transfer temperature difference, realizes isothermal heat transfer, is finally reached refrigerant temperature Cooling water temperature, i.e. air's wet bulb temperature are infinitely close to, reduces compressor power consumption, improves the efficiency of whole refrigeration system.
Brief description of the drawings
Fig. 1 is the structural representation of transverse flow multistage devaporizer.
In figure:11st, first-class heat exchanger;21st, one-level filler;12nd, secondary heat exchanger;22nd, two level filler;13rd, three-level exchanges heat Device;23rd, three-level filler;3rd, blower fan;4th, collecting-tank;5th, water pump;6th, shower;7th, nozzle.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer Type embodiment is further described.
Referring to Fig. 1, a kind of transverse flow multistage devaporizer, including first-class heat exchanger 11, one-level filler 21, two level are changed Hot device 12, two level filler 22, three-level heat exchanger 13, three-level filler 23, blower fan 3, collecting-tank 4, water pump 5, shower 6, nozzle 7, Cooling water, refrigerant.The input of the first-class heat exchanger 11 is refrigerant inlet, and its output end is defeated with secondary heat exchanger 12 Enter end to be connected;The input of the three-level heat exchanger 13 is connected with the output end of secondary heat exchanger 12, and its output end is refrigerant Outlet;The input of water pump 5 is connected with the output end of collecting-tank 4, and its output end is connected by shower 6 with nozzle 7.
The operation principle of the utility model multistage influence diagram device is:Cooling water is transported to top from collecting-tank 4 via water pump 5 The shower 6 in portion, sprayed respectively by first-class heat exchanger 11, one-level filler 21, secondary heat exchanger 12, two level filler through nozzle 7 22nd, three-level heat exchanger 13, three-level filler 23 drip back into collecting-tank 4 after being exchanged heat.Refrigerant is transported to first-class heat exchanger 11, high The gaseous refrigerant of temperature carries out a heat exchange with low-temperature cooling water, and the refrigerant after cooling enters secondary heat exchanger 12, heats up Cooling water be dropped on one-level filler 21 and form very thin moisture film, absorbed heat with part water in moisture film after Cryogenic air laterally heat exchange Vapor is evaporated to, the cooling water after remaining cooling is dropped on secondary heat exchanger 12 carries out secondary heat exchange with refrigerant.It is secondary Refrigerant after heat exchange is exchanged heat three times into three-level heat exchanger 13, after finally refrigerant temperature is reached air's wet bulb temperature Output.
If refrigerant temperature is still higher than air's wet bulb temperature after exchanging heat three times, heat exchange number can be increased until refrigerant temperature Untill degree is infinitely close to air's wet bulb temperature.
