4, there is volume little, joint space-efficient feature, the utilization rate that can save shell material, high-efficiency compact.
Accompanying drawing explanation
Fig. 1 is the structural representation of facing of the present utility model.
Fig. 2 is side-looking structural representation of the present utility model.
Fig. 3 is plan structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
Heat exchanger is a kind of heat-exchange apparatus, is mainly the part heat of hot fluid is passed to cold fluid.It of a great variety, uses in extensive rangely, is the common apparatus of a lot of industrial departments such as oil, power and chemical industry.Current seawater source heat pump system Intermediate Heat Exchanger adopts titanium sheet heat exchanger more, and because titanium material is expensive, Intermediate Heat Exchanger investment is larger, has increased the initial cost of system.
Consider that Intermediate Heat Exchanger cleans in the future and the convenience of maintenance, as shown in Figure 1, 2, 3, the utility model is designed to open type slot type heat exchanger, comprises cell body 1 and heat exchanger tube 3.In described cell body 1, there are a plurality of shelves 2, be provided with on the sidewall of shelf 2 and have seawater water inlet 51 and seawater delivery port 52, path between seawater water inlet 51 and seawater delivery port 52 is stopped by described shelf 2 parts, form broken line path, its object is to increase heat-exchange time, fully heat exchange, is also conducive to reduce seawer tide for the impact loss of heat exchanger simultaneously.Every three heat exchanger tubes 3 form a tube bank, and heat exchanger tube 3 is fixedly mounted in described cell body 1 by pipe bundle plate 6.Described heat exchanger tube 3 cavitys are communicated with formation working medium liquid passage, and described working medium liquid passage two ends are working medium liquid liquid inlet 41 and working medium liquid liquid outlet 42.Working medium liquid in the present embodiment is ethylene glycol solution, is also in the outer cell body of heat exchanger tube 31, to be seawater passage, in heat exchanger tube 3, be ethylene glycol solution passage, cold and hot fluid employing counter-current flow pattern.The utility model slot type heat exchanger structure can be used as evaporimeter and condenser uses, and can be also that parallel connection or tandem compound connect and pipeline, can meet all size system and use.Due to the turn back return-flow structure design of its inside, there is runny navigation channel, with the speed of guaranteeing that water is clear, unified, be not easy to occur the stifled and dirt of ice; And it is little to have volume, joint space-efficient feature, the utilization rate that can save shell material, high-efficiency compact.
The present embodiment design parameter is: seawater flow process is three flow processs, and centre is separated by two longitudinal shelves 2.Each flow process has 4 layers of tube bank, and each tube bank comprises three heat exchanger tubes 3, pipe range 3m, and transverse pipe spacing 12.5mm, longitudinal pipe spacing 44.5mm, pipe external diameter 25ram, wall thickness 2.5mm, cell body 1 is of a size of: 8200mm * 500mm * 3100mm.
Described cell body 1 inwall and heat exchanger tube 3 outer walls all have anticorrosive coat, and described anticorrosive coat has played seawater corrosion prevention and anti-scaling action, and long-term operation can reduce dirt generation, minimizing dirtiness resistance.Described anticorrosive coat can be epoxy resin coating anticorrosive coat, bituminous epoxy anticorrosive coat and zinc silicate paint anticorrosive coat, can be also the passivating film of sandwich construction, is specially: silica-silicon nitride-alundum (Al2O3) passivating film.The first passivation layer is low temperature deposition silica, can absorb and stop that the corrosive ions such as sodium, chlorine spread to silicon substrate; The second passivation layer is that chemical vapor deposition silicon nitride stops the contamination of objectionable impurities to tube wall surface; Top layer passivation layer is alundum (Al2O3), and object is to make surface passivation protective effect better and make metal layer not be subject to the machinery scratches such as sea sand.
By to the utlity model has anticorrosive coat heat exchanger heat-transfer performance test and with the comparison of isostructure without anticorrosive coat heat exchanger heat-transfer performance, the heat exchanger thermal conductivity factor that structure shows to have anticorrosive coat is 3.69W/(m.K); When velocity in pipes is less than 1.5m/s, the former is apparently higher than the latter, and proved utility model can significantly improve Energy Efficiency Ratio in seawater source heat pump system.
It should be noted that; particular of the present utility model have been described in detail the utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
