The specific embodiment
As shown in Figure 1 and Figure 2, the utility model efficient evaporation cooler includes one the tube bank case 6 in realization evaporative cooling space and the cooling water pipeline of reciprocal circulation capable of circulation is provided, in the tube bank case, be equipped with heat-exchanging tube bundle 5, the cooling water pipeline section of the top of heat-exchanging tube bundle has one group can be with the shower nozzle 9 of cool water shower to the heat exchanger tube, and tube bank case top is one group of cooling air generation device 7; The bottom position that is positioned at efficient evaporation cooler has cooling water water tank 2, and section has air shutter 3 between tube bank case and cooling water water tank.
Described heat-exchanging tube bundle 5 is one group of node heat exchanger tube with concavo-convex outer wall of placing side by side.In the embodiment shown in fig. 1, set up an Inlet and outlet water tube sheet case 11, the centre is provided with a dividing plate 12 to form upper and lower two parts compartment, needs being contained in respectively in two compartments into and out of pipeline opening 10,13 of cooling recirculated water; The node heat exchanger tube that node heat-exchanging tube bundle 5 upper and lower half are divided has formed upper and lower circulation passage; The same side of upper and lower passage respectively with need coolings recirculated water into and out of pipeline opening 10,13 UNICOMs, another side forms UNICOM and can reflux by backflow tube sheet case 4 is auxiliary.
The construction profile of node heat exchanger tube is referring to shown in Figure 3.
In the embodiment shown in fig. 1, one group of cooling air generation device 7 of tube bank case top can adopt blower fan.
Described cooling water pipeline is furnished with pumping system 16; In cooling water pipeline, add strong magnetic antisludging equipment 14.
Before the delivery port of cooling water water tank 2, be provided with downflow weir 17, water fender 18; A water tank inclined bottom plate 19, aspect delivery port rightabout are laid in the bottom.
For saving purpose, above the node heat exchanger tube, be provided with water saving flap sheet 8.
The heat-exchanging tube bundle of the utility model efficient evaporation cooler has adopted stainless steel node heat exchanger tube as heat exchange element, because the profile of node heat exchanger tube concave-convex surface, form stronger turbulent flow and disturbance when recirculated water is flowed and be turbulent condition in pipe, make recirculated water in pipe in the process of flowing, pressing close to the recirculated water of tube wall and the recirculated water of tube hub constantly mixes, make circulating water cooling even, in addition, the concavo-convex profile of node heat exchanger tube increases its surface area greatly, thereby improve heat exchange efficiency greatly, make the whole heat exchange efficiency of efficient evaporation cooler improve 2-3 doubly than the heat exchange efficiency of general plain tube bank or finned-tube bundle; The stress that the expanding with heat and contract with cold of bellows tube produces with stress absorption, so has the self-compensation situation function by concavo-convex profile, and the interface thermal stress with the tube sheet case is reduced, and can not occur that the mouth of pipe breaks and the leakage that causes makes the devaporizer safety durable; Because it is the variation of the profile that the tube wall that the node heat exchanger tube is caused by recirculated water water temperature variable effect is concavo-convex comes off the incrustation scale that hardens on tube wall voluntarily, has self-cleaning action, therefore less scaling; Before the delivery port of cooling water water tank, design has the rightabout water tank inclined bottom plate of baffle plate and downflow weir and aspect delivery port, and the water quality of cooling circulating water is improved.
The course of work of the utility model efficient evaporation cooler is: when efficient evaporation cooler puts into operation, after needing circulating water cooled to enter into Inlet and outlet water tube sheet case 11 from circulating water inlet 10, separated by the dividing plate 12 in the Inlet and outlet water tube sheet case 11, after entering the upper bundle of node heat exchanger tube 5 from the top of Inlet and outlet water tube sheet case 11, flow into backflow tube sheet case 4, the recirculated water that enters into backflow tube sheet case 4 enters into the bottom of node heat exchanger tube 5 from the bottom of backflow tube sheet case 4, then, flow out from circulating water outlet pipe 13 after entering into the bottom of Inlet and outlet water tube sheet case 11 dividing plates 12.When recirculated water need be lowered the temperature, open cooling water water pump 16, cooling water in the water tank 2 is extracted out, flow out from cooling water outlet pipe 15 through supercooled water water pump 16, strong magnetic antisludging equipment 14 on cooling water outlet pipe 15 outer tube walls makes cooling water less scaling, cooling water enters in the evaporative type cooler and sprays on the node heat exchanger tube 5 of below from shower nozzle 9 then, make the heat and the cooling water of the recirculated water of node heat exchanger tube 5 tube walls absorption carry out heat exchange, utilize cooling blower 7 to be drawn into next air from air shutter 3, below cooling blower 7, form low-pressure area, make the cooling water evaporation and the cooling that spray, the heat of node heat exchanger tube 5 is taken away, when water vapour rises through water saving flap sheet 8, water vapour bumps with the plate of water saving flap sheet 8, condense into big water droplet and fall after rise, above process reaches the purpose that reduces the recirculated water water temperature and save cooling water.Flow to the water tank 2 of below behind the node heat exchanger tube 5 downwards when cool water shower, enter into simultaneously in the water tank 2 after cooling water contact the dust afterwards brought into air in the process that falls after rise and the incrustation scale that produces during with 5 heat exchange of node heat exchanger tube comes off, be deposited in above the water tank inclined bottom plate 19 of water tank 2, when cooling water when water pump 16 directions flow, because water tank inclined bottom plate 19 aspects are opposite with water (flow) direction, so, the precipitation suspension of post precipitation can not flow to water tank 2 water outlet directions, cooling water flow can only overflow from downflow weir 17 tops by the back from the bottom of water fender 18 during to water fender 18, enters cooling water water pump 16 then and finishes cool cycles.The precipitation suspension of post precipitation water tank bottom sewage draining valve 1 from the lowest part of water tank 2 when water tank 2 cleans is discharged.
The various embodiments described above can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit claim of the present utility model.
