Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further elaborated.
This utility model one single loop high capacity chiller, has oil circulation loop and wind closed circuit, improves cold
But the grease chamber's structure in the oil circulation loop of device, flow-disturbing silk structure and the air duct structure of wind closed circuit.As shown in Figure 5,6,
Upper and lower grease chamber sidewall in oil circulation loop installs arc deflector 1 with end face junction, reduces oil circulation resistance, water conservancy diversion
Plate is arcuate structure；Grease chamber's oil-in flange 3 is made, by centre position deflection, the side that oil stream line is identical；In wind closed circuit
In ventilating duct 4, end face is round and smooth excessive streamlined windward, and ventilating duct side plate 5 is inclination angle type.As it is shown in fig. 7, grease chamber's inner fin
Connection at tube end and tube sheet is plane.As shown in Figure 4, flow-disturbing silk uses three-dimensional Double helix band reinforcement shape, increases strengthening
Flow-disturbing effect.
Ventilating duct increases deflector, improves wind side flow regime and reduce resistance, increase ventilating duct intensity.
After finned tube is arranged to tube bank, finned tube positioner is used to position between finned tube, it is ensured that finned tube
Gap, improves stability when cooler runs, it is ensured that effective operational factor of blower fan and then guarantee realize cooling down greatly appearance
Amount.
Finned tube positioner includes location-plate 10, and as shown in Figure 8, it is inserted between multiple finned tube 7, location-plate 10
Generally plank frame, its edge is provided with multiple recess of corresponding supervisor's external diameter when arranging with finned tube 7.Finned tube positioner
Also having pressure zone 11, pressure zone 11 two ends are fixed on tube bank case both sides side plate 14, compress location at finned tube tube bank above-below direction.
Described pressure zone 11 is fin anti-bending type structure, and it includes base plate and the fin being perpendicular on base plate, and base plate two ends are provided with connecting hole,
It is connected with tube bank case both sides side plate 4 by jackscrew 13 or bolt.Tube bank case both sides side plate 4 vertical direction is provided with multiple groove,
Recess width is identical with location-plate thickness, when making installation location-plate, can just be fastened on the groove of tube bank case both sides side plate 4.
In the present embodiment, cooler is the single loop forced oil-circulation forced air cooler manufactured by improving design, uses
Steel-aluminum composite fin tube is as cooling element, and finned tube uses and couples with Tube-sheet Welding mode, and intensity is good, non-leakage；Stream plate is adopted
It is processed into arc with material steel plate similar with grease chamber through veneer reeling machine, inside grease chamber, specifies position welding (as shown in Figure 5)；Cooling
The welding of device finned tube is changed into downhand welding by fillet welding, uses Special Automatic welder, and weld seam smooths, and without the mouth of pipe protruded during fillet welding, changes
It is apt to oily stream mode, decreases drag losses.(as shown in Figure 7)；Cooler flow-disturbing silk is three-dimensional Double helix band reinforcement form
(as shown in Figure 4), use No. 20 steel, make with reinforcement spot welding after thermally treated and machine-shaping, manufacture process uses specially
Flow-disturbing silk outside dimension is strictly controlled, it is ensured that solder joint is firmly (postwelding does sampling examination) with mold.
The capacity of cooler is played an important role by flow-disturbing silk, installs flow-disturbing silk cooler cold compared with not installing flow-disturbing silk
But capacity at least differs 2 to 3 times, and flow-disturbing filate formula is also the key factor determining cooler capacity.Double helix flow-disturbing silk increases
Flow-disturbing effect, makes fluid be more easy to into turbulence state, although oil resistance increased, but test result indicate that cooler interior oil hinders
Being 27KP during power fall rated operation point, be normally used below 1000r/min, lift is that the oil pump of 5mH2O is entirely capable of meeting cooling
Device runs, and product is bright through Beijing atomic energy science academic test (examination) checking, and cooler capacity reaches to design requirement.Flow-disturbing silk installation form is such as
Shown in Fig. 9.
Cooler ventilating duct changes airflow design into, the most former right angle change into as shown in Figure 6 round and smooth excessively, lead
Air duct side plate is inclination angle type, eddy current when decreasing wind flow in ventilating duct and segregation phenomenon, improves wind path circulation, reduces
Windage, reduces noise.
This utility model is through operation test, and various performance parameters all meets country and industry standard.
