Description

The cantilever style evaporative condenser

The utility model relates to refrigeration plant, specifically a kind of cantilever style evaporative condenser.

We know that the condenser that uses in the Refrigeration Technique can be divided into water-cooled.Three kinds of air-cooled and vaporation-types, evaporative condenser is because water saving and advantage such as energy-conservation, so use more, but the end and the pars intermedia of each the root condenser coil in traditional evaporative condenser all are connected to a fixed with condenser shell, or the end of every condenser coil and pars intermedia all are connected to a fixed with the framework of setting, framework is fixed with condenser shell again, because cooling water is in the constantly evaporation of the surface of condenser coil, crystalline deposit from water and the crystal grain that forms in water because Blang's warm-up movement and constantly colliding with the condenser coil surface, thereby provide the chance of crystal growth, small crystals constantly forms megacryst, the dirt layer on condenser coil surface is constantly thickened, have a strong impact on heat transfer, in addition, this condenser generally uses water quality water preferably, promptly uses the water of handling through softening, causes the operating cost height, the deficiency that maintenance cost is high.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of rational in infrastructure, novel, efficient is high, the life-span is long, cost of use is low cantilever style evaporative condenser is provided.

For achieving the above object, the utility model can reach by following measure: a kind of cantilever style evaporative condenser, it is provided with blower fan, casing, forecooler, water fender, water drenching device, discharge, collector tube, condenser coil, ball-cock assembly, cooling water pump, water tank, it is characterized in that the condenser coil group is by some condenser coils, discharge, collector tube and support plate are formed, the two ends of every condenser coil are connected with collector tube with discharge respectively, the both ends of condenser coil are provided with support plate respectively, the middle part of condenser coil suspends, and the condenser coil group is connected with casing through support plate.

The utility model is owing to adopt said structure, and every condenser coil middle part suspends, and it produces vibration when work, makes the sticking incrustation scale of condenser coil, have rational in infrastructure, novel, efficient is high, installation, advantage such as easy to use.

Accompanying drawing is a structural representation of the present utility model, also is the schematic diagram of a kind of embodiment.

Mark among the figure: blower fan 1, casing 2, forecooler 3, water fender 4, water drenching device 5, discharge 6, condenser coil 7, collector tube 8, ball-cock assembly 9, water tank 10, cooling water pump 11, support plate 12, end socket 13.

Below in conjunction with accompanying drawing the utility model is further described: as shown in the figure, a kind of cantilever style evaporative condenser, it is provided with blower fan 1, casing 2, forecooler 3, water fender 4, water drenching device 5, discharge 6, collector tube 8, condenser coil 7, ball-cock assembly 9, water tank 10, cooling water pump 11, forecooler 3 adopts copper pipe dish system to form, promptly the coiled pipe of being arranged by several row of horizontal is formed, and be fixed on the casing 2, the arrival end of forecooler 3 is connected with the refrigeration machine blast pipe, the port of export is connected with discharge, forecooler 3 belows are provided with water fender 4, water fender 4 can adopt finned, also be fixed on the casing 2, water fender 4 has water drenching device 5, the structure and the connected mode of water drenching device 5 are same as the prior art, discharge 6 and collector tube 8 adopt flat copper pipe or other copper pipe to make, its two ends are blocked by end socket 13, one side of discharge 6 and collector tube 8 is provided with several holes that is connected with condenser coil 7, condenser coil 7 adopts the copper pipe bending to form, its two ends are connected with hole on the collector tube 8 with discharge 6 respectively, the both ends of every condenser coil 7 are connected with support plate 12 respectively, can on support plate 12, be provided with several holes, on the every condenser coil 7, the hole that the bottom is passed respectively on the support plate 12 is connected with discharge or collector tube, also can adopt other method make condenser coil 7 on, following both ends are connected with support plate 12, support plate 12 can be provided with one respectively at the both ends up and down of condenser coil 7, also can be provided with two respectively at the both ends up and down of condenser coil 7, can also be provided with two support plates in the upper end of condenser coil 7, the bottom of condenser coil 7 is provided with a support plate, the condenser coil group is by some condenser coils 7, discharge 6, collector tube 8 and support plate 12 are formed, the condenser coil group is connected with casing 2 through support plate 12, the end of the condenser coil group in the condenser coil group of this connected mode is connected with casing 2, the middle part of condenser coil group is not connected with casing 2, the middle part of condenser coil 7 is in suspension, the structure and the annexation of other each parts of the utility model are same as the prior art, and this does not give unnecessary details.

Condenser coil of the present utility model is owing to adopt said structure to fix, the condenser coil middle part suspends, when water, gas skim over outside managing, when the liquid phase of the Heavy Weight of condenser coil surface attachment enters lightweight gas phase, under the effect of gas-liquid interface power, the outer phenomenon that will be brought out a kind of flowing instability of condenser coil, this phenomenon is called Taylor's fluctuation (Fig. 5); Tube refrigerant is condensed into the liquid process from gaseous state, will the conversion (Fig. 6) of fluidised forms such as annular flow, transition flow, laminar flow, gap impingement flow takes place respectively, the fluctuate acting in conjunction of fluidised form and tube refrigerant fluidised form of the outer Taylor of pipe, make the condenser coil of suspension produce the chatter of certain frequency, thereby make dirty thing crystal grain be difficult on the condenser coil surface, adhere to growth.

During the work of cantilever style evaporative condenser, the high-temperature high-pressure refrigerant steam of discharging from compressor at first enters precooling organ pipe group, distribute to the horizontally disposed serpentine coil of each root, after preliminary cooling, enter discharge, distribute to the vertically arranged serpentine coil of each root by discharge again, it is condenser coil, emit latent heat therein and be condensed into liquid state, flow out evaporative condenser through collector tube, cooling water pump pumps to the top of pipe group with the water in the water tank, drenches pipe group surface through water drenching device, part water heat absorption evaporation, other water enters water tank, so circulation; Blower fan is contained in the top, and air is evenly sucked from the casing below, when air is flowed through condenser coil, takes away water and evaporates and the steam of formation, makes the outer evaporation heat absorption of pipe continue to carry out, thereby makes the condensation exothermic process of managing interior cold-producing medium continue to carry out.

The utlity model has rational in infrastructure, novel, efficient is high, meet environmental requirement, energy savings, make With life-span length, installation, the advantage such as easy to use, can realize that one drags four, one to drag five even one to drag six, make central hollow Transfer in into family.
