Description
Technical field:
The utility model relates to refrigerating plant, particularly evaporative condenser.
Background technology:
Condenser is indispensable refrigeration plant in refrigerating plant, and evaporative condenser is a kind of heat that utilizes evaporation of water latent heat and sensible heat to take away process fluid, finishes the cooling condensation process to process fluid.In refrigerated air-conditioning system, the application of evaporating type condensing is very general, has good result energy-conservation, water saving.Most refrigerated air-conditioning systems all adopt evaporative condenser, and these evaporative condensers all adopt tubular structure, and the evaporative condenser of these tubular structures is to change on the shape of pipe and variations in flow.At present, the main core component of the evaporative condenser of producing is a condenser coil both at home and abroad, and condenser coil adopts cast to mainly contain following several mode: as pipe, elliptical tube, drop shaped tube, alternating curved bellows etc., from material all is steel pipe basically, and steel pipe is lower as condensing heat-exchange component heat current density, in order to guarantee the equipment heat exchange property, enough pipe areas must be arranged, therefore on volume, can't dwindle again, be difficult to have concurrently high heat-exchanging performance and the little advantage of volume.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and the wavy plate evaporation cold type of a kind of efficient some condenser is provided, and integrates efficient, compact conformation, volume is small and exquisite.
The technical scheme that the utility model is adopted for achieving the above object is: efficiently put wavy plate evaporation cold type condenser, spray system, heat-exchanging component, PVC dehydrater and PVC heat exchange layer from top to bottom mainly are housed in the casing, and heat-exchanging component is to be made of the plate that two inside have tortuous internal channel.
Described heat-exchanging component is to be connected by two plate spot welding, forms the inner plate-sheet-type heat-exchanging component that has tortuous internal channel, and plate outer surface solder joint place is a spill.
Solder joint is pressed the equilateral triangle arrangement on the described heat-exchanging component plate.
Described plate is a metallic plate, and thickness is 0.5mm-2.0mm.
Described plate is selected plates such as carbon steel sheet, corrosion resistant plate or titanium alloy sheet for use.
Every plate of described heat-exchanging component is erect and is installed on the casing.
Described heat-exchanging component bottom Corner Strapped is installed in casing top, welded seal between plate.
Described PVC heat exchange layer is serially connected every heat exchange layer by steel pipe, and the grouping independent suspension is installed in lower box.
Described PVC heat exchange layer has V-type water distribution minor groove and the big groove of U type transversal ventilation, and V-type water distribution minor groove is arranged by " Z " type and arranged.
Blower fan system is equipped with on described casing top, and motor directly is connected with impeller, and motor is fixed on the upper side of casing 1, by two supporting traverse fixed electrical machinery seat boards.
Described PVC dehydrater, the reinforcement of the outside and top band projection in the inclined to one side peak, every dehydrater is cascaded by support and fixed bar.
The utility model condenser heat-exchanging component adopts board-like, plate is through being welded into the round dot of different spread patterns, after pressure forming, constitute condensing heat exchanger assembly again with a corrugated outer surface and tortuous internal channel, the solder joint place is recessed on the plate face, weldering is local not protruding, make heating surface be a little wavy, the two sides of plate all is a heat-transfer area, form the corrugated fluid passage in the plate chamber, leave certain spacing between the plate, its size is carried out designing and calculating according to fluid flow. and the ammonia refrigeration system that adopts the wavy plate evaporation cold type of this efficient some condenser is not only at the unit material, remarkable advantages is arranged on the volume weight, and the coefficient of performance is also wanted high 10%-20%, install simple and conveniently, safeguard and transportation can be reduced expenses, reduce cost. be embodied in:
1. heat transfer coefficient height.After wavy plate condensing heat-exchange assembly was selected in employing, the flow velocity size and Orientation of fluid in flow process constantly changed, and aggravated the turbulence effect of fluid.Plate is intrafascicular because of no baffle plate, so no flow blind angle or dead band.The plate spacing can be made lessly, and the outer flow passage size is approaching substantially in making, and the heat exchanger heat transfer coefficient is significantly improved.
2. facility compact, volume is little.Because heat transfer coefficient, heat transfer efficiency height realize that the area of the identical needed heat transfer element of heat output descends.
3. sealing means is reliable.Adopt the welding manner sealing between plate, have the twice weldering to meet usually, can guarantee not take place fluid and leak, two kinds of fluids can not mix.
4. scale removal performance is good, economical operation safety.Be corrugated owing to put wavy plate evaporation cold type condenser heat transfer element, solder joint is pressed equilateral triangle and is arranged, form changing tortuous passageway in the plate, not only strengthened the turbulence effect of plate inner fluid, and make fluid in plate in the flow process flow velocity and direction constantly change, therefore strengthened the souring of fluid, made heat-transfer area less scaling whole heat exchange wall.Plate end in casing is fixed, and the other end is a free end, is easy to bulk deformation when therefore moving.Because hard scale is different with the thermal coefficient of expansion of metal, hard scale can come off in process of expansion and contraction automatically, by fluid removal, plays self-cleaning effect.
5. simple in structure, convenient disassembly.The condensing heat-exchange assembly can integral body be pulled out, and is convenient to clean and maintenance.As required, plate can freely be changed.Plate spacing and arrangement mode are flexible, can design according to customer requirements.
6. corrosion-resistant, long service life.Plate is made by stainless steel, can adopt the manufacturing of titanium plate for the fluid that contains chlorion, has guaranteed the service life of heat exchanger.Solder technology is adopted in the welding of plate, has strengthened the rigidity of selecting wavy plate, makes thin plate can bear higher operating pressure.The utility model can be widely used in the various refrigerating plants of industries such as coal, chemical industry, oil, medicine, beer, food processing.
