Description
Technical field
The utility model relates to the cooling device of a kind of cooling water (or other need cooling fluids), be can make that cooling water (or other need cooling fluids) does not directly contact with air, closed cycle, easily manufactured, cost is low, the scope of application is wide, the closed cooler of long service life.
Background technology
The radiator of present closed cooler is to use pipe heat exchanger, is snakelike cooling coil.Need the higher cooling water (or other need cooling fluid) of temperature of cooling in serpentine coil, to flow, heat is passed to the outer surface of cooling coil with the form of convection current from the inner surface of cooling coil, the outer blower fan exhausting of coil pipe or increase spray recirculated water again reaches the cooling purpose by convection current and evaporation.
Though the closed cooling apparatus of this tubular type has many good qualities, but still there are many weak points.Because heat transfer coefficient is little, do not hold that the temperature difference is big, sealing factor is high, NTU is lower, to fixed heat transfer coefficient and thermal capacity, the heat exchange area of heat exchanger is just big, therefore it is a lot of to need to consume material, Heavy Weight, make also more complicated and trouble, one time investment cost is also just very big, causes and uses enterprise less; Overhaul in addition, clean very inconvenient, the heat resisting and pressure resisting ability is also low, and is antifreeze, anti-freezing property is also poor, so that the scope of application is narrow and service life is short.
Summary of the invention
In order to overcome these weak points, the utility model provides a kind of closed cooler of novelty, this closed cooler not only has identical enclosed with the closed cooler of present use, the advantage that recycles, also has its heat exchanger heat transfer coefficient height, logarithmic mean temperature difference (LMTD) is big, NTU is big, volume is little, in light weight, price is low, end does not have a narrow range of temperature, sealing factor is low, the heat resisting and pressure resisting ability is good, antifreeze, anti-freezing property is strong, maintenance, clean superiority such as convenient, the maintainability of equipment is improved greatly, increase service life, the scope of application enlarges, therefore first simultaneously investment also reduces, has bigger economic benefit, original because first input expense can not use the enterprise of closed cooler also can use too greatly, enlarged the use enterprise-wide.
The technical scheme that its technical problem that solves this novel practical adopts is: a kind of closed cooler, it is characterized in that heat exchanger is a plate type heat exchanger, comprise: the spray water tank is fixed on the base, the spray water tank is installed the spray water pump outward, shower water upper box part fixed frame casing, the framework casing has top and no top boundary to separate with the spray water tank, and the framework casing that the spray water tank does not have top portion top is provided with air inlet, filler, nozzle, water collection device from bottom to top, and the air inducing blower fan is installed on its top.Opposite side promptly has top shower water upper box part to arrange plate type heat exchanger in the framework casing, it is the ripply sheet metal of compacting, space between adjacent two is the runner of cold and hot fluid, need the hot fluid heat of cooling to rely on convection heat transfer' heat-transfer by convection to take away by cold fluid, two runners respectively have a pair of import and export.The import and export of the hot fluid runner cooling water (or other need cooling fluid) higher with temperature is connected, the import of cold fluid runner is connected with the shower water pump discharge pipe, its outlet is connected with the nozzle pipe of casing opposite side, makes plate type heat exchanger cold fluid runner, nozzle, spray water tank, spray water pump form the recirculated water circulation.
On base, spray water tank, spray water pump, air inlet, heat-exchangers of the plate type, casing, water collection device, nozzle, filler, air inducing blower fan, fit together, spray water tank, spray water pump, plate type heat exchanger, nozzle pipe connect, the device that forms a whole is provided with a pair of import and export supply and demand cooling water (or other need cooling fluids) turnover.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
This figure is the structural representation of utility model.
1. air inducing blower fans among the figure, 2. water collection device, 3. nozzle, 4. filler, 5. plate type heat exchanger, 6. air inlet, 7. spray water tank, 8. spray water pump, 9. cooling water (or other need cooling fluid) import, 10. cooling water (or other need cooling fluid) outlet 11. framework casings 12. spray water tanks have top portion 13. spray water tanks not have top portion
The specific embodiment
In the accompanying drawings, fixing spray water tank (7) on the base of cooler, spray water tank (7) top fixed frame casing, the framework casing has top and no top boundary to separate with the spray water tank, the framework casing on the no top portion of spray water tank (7) top is provided with air inlet (6), filler (4), nozzle (3), water collection device (2) from bottom to top, and air inducing blower fan (1) is installed on its top.Heat-exchangers of the plate type (5) is installed in the interior opposite side of framework casing, and spray water tank (7) has top portion top.The a pair of import and export of heat-exchangers of the plate type (5) is as import (9), the outlet (10) of hot fluid, for being connected with the cooling water (or other need cooling fluid) of need cooling.Another then is the import and export of cold fluid to import and export, the shower water that will be sprayed in the water tank (7) by spray water pump (8) injects from its import, its outlet is connected with nozzle (3) pipe of opposite side in the framework casing, falls into spray water tank (7) through spray, recycles.Air inducing blower fan (1), air draft outward, air enters from air inlet, in framework casing one side box body from bottom to top, with the shower water reverse flow, by convection current and evaporative cooling shower water, the damp-heat air that produces in the cooling procedure is loose in air by air inducing blower fan (1).In air inducing blower fan (1) import department water collection device (2) is installed, the little water droplet when damp-heat air passes through water collection device (2) in the interception damp-heat air.In order to make shower water long-pending with air contacting surface as wide as possible, prolong flow process, to increase the damp and hot exchange between the aqueous vapor, liquid distribution one filler (4) is installed between nozzle (3) and cooler air inlet (6).Whole closed cooler is to spray water tank, spray water pump, air inlet, plate type heat exchanger, casing, water collection device, nozzle, filler, air inducing blower fan on base, fit together, spray water tank, spray water pump, heat-exchangers of the plate type, nozzle pipe connect, the device that forms a whole is provided with a pair of import and export supply and demand cooling water (or other need cooling fluids) turnover.
