Description of drawings
Fig. 1 is the structural representation of an embodiment of mixed flow type evaporative condenser.
Fig. 2 is the structural representation of the circular nest plate condenser pipe of condenser.
Fig. 3 is that A among Fig. 2 is to view.
The specific embodiment
As shown in Figure 1, in one embodiment of the invention, evaporative condenser comprises spray system 1, refrigerant inlet 2, circular nest plate condenser coil 3, refrigerant outlet 4, PVC (polyvinyl chloride) heat radiation filler 6, blower fan 8, dehydrater 9, collecting-tank 12 etc.
In preferred embodiment of the present invention, evaporative condenser also comprises upper hose 5, water circulating pump 7, maintenance pedal 11, condenser metal shell 10.
As shown in Figures 2 and 3, circular nest plate condenser pipe 3 comprises parent tube 31, in the appearance surface cover of parent tube 31 circular nest plate 32 is arranged, and 31 of the flange of nest plate 32 and parent tubes adopt hydraulic expanding plumber processings of planting, and in conjunction with tight, improve heat transfer effect.
As shown in Figure 2, two adjacent circular nest plate 32 spacings are 12mm, not only increased the heat exchange area in the volume but also can not form the water bridge, and the heat exchange of having avoided causing because of the water bridge is lost, and guarantees condensation, the cooling performance of condenser pipe 3.The wing height of circular nest plate 32 is 10mm.Nest plate 32 circularizes distribution outside parent tube 31, be conducive to manage outer media flow, will manage the timely carrying-off of outer flow media, guarantees the outer media flow of pipe.
The nest plate 32 that previous embodiment is used and the contact-making surface of parent tube 31 adopt the version that rises and connect, with compare compactness around sheet and improve, thereby can strengthen heat exchange, in addition, owing to can produce fold around sheet in processing, produce easily incrustation scale, and adopt nest plate just can avoid this defective, also have in addition the advantages such as easy to clean.
