Abstract: Spider fans at home and abroad in recent years, heat transfer components and high Zhang Heat exchanger Research overview, describes the new validation of heat transfer components and the structure of the piece of shell books and progress in the development of highly efficient heat exchanger, and cooling plate heat exchanger with the structure and characteristics of plate heat exchangers in refrigeration technology The application and development were discussed. Key contact: enhanced heat transfer; shell rent structure; efficient heat exchanger; plate heat exchanger; Ping-fit
Key words: TU832.2 10 3 Document code: B
1. Enhanced heat transfer components and high efficiency heat exchanger Research
1.1 Rod Cross grave tube heat exchanger
This is the combination of rod baffle heat exchanger technology and striped tube strengthen an efficient heat exchanger technology. Rod baffle heat exchanger is the Philips in the last century the United States 70 years to solve the gas fluid heat exchanger induced vibration of the development of a rod baffle heat exchanger. Characterized by strong vibration, eliminating the dead zone shell, the shell fluid to improve the speed and temperature distribution. Guilin Chemical Machinery Plant with the South China University of Technology Professor Qian Songwen Cooperation And successfully describe tube spiral tube heat exchanger for Rod heat exchanger, saving nearly 60% of the heat transfer area, the effect is very significant. At present, the spiral rod Rod plant heat exchanger have been systematic chemical production in Guilin . In recent years, Guilin Chemical Machinery Plant, South China University of Chemical Engineering Institute and the State Education Commission of heat transfer and energy research and development laboratories, will be under the same heat transfer efficiency of internal velocity than the stripes and spiral pipe plant pipe used for the Baffle In May heat .1995 DN1400 stripes design and manufacture of heat exchanger tube rod baffle a medium-sized fertilizer plants in Yunnan, the system input transform industrial operation, replacing the original use of the DN2400 tubular baffle Banzhu heat exchangers, 540mZ the heat transfer area to replace the original equipment 1627m, the heat transfer area, equipment, weight reduction from the original 37.61d to 17.27d, equipment investment to save 1 / 3. application of enhanced heat transfer elements and the development of highly efficient heat exchanger : greatly improved the company's economic and social benefits. Transverse Rod heat exchanger tube development and application of the results show that enhanced heat transfer elements and the organic combination of Rod. in improving the heat transfer rate of tube well improve the heat transfer rate shell. industrial operation that striped tube with heat transfer efficiency, fluid resistance, vibration resistance and good.
1.2 zoom tube full round hole pumping heat exchanger baffle Shan
Our existing medium-sized hydrogen nitrogen fertilizer plant Compressor Cooler for a long time with low heat transfer efficiency, cooler flow path smooth, fluid cross flow heat exchange caused by the vibration has been the unresolved technical problems, directly affect the efficiency of nitrogen compressor. Zoom control the entire round slot baffle plate heat exchanger plant in nearly two years, other schools to develop a new type of heat exchanger, are another new type of enhanced heat transfer components and baffled shell structure of the optimal combination. usually that of the enhanced convection to the heat is repeated to change the vertical pressure gradient effect of fluid flow, this flow pattern followed by the alternate expansion and contraction section to achieve. big boy studies have shown, wave channel under the same flow resistance, higher than the parallel flow The heat transfer performance. Scaling governing their effective use of the extended segment, contraction also used to improve the fluid velocity the effect of adhesion; whole round garnet hole baffle plate or baffle plate for a full round-shan not open mouth bow The wash through each row in Tubes bridge, lattice parameters can hole the size required to determine the flow rate. The newly developed high efficiency heat exchanger medium-sized fertilizer plants in China to replace the hydrogen nitrogen compressor made one, two, three paragraphs back to the original cooler ring baffle. zoom control whole round slot baffle plate heat exchanger operating results of the operation of industrial applications that have a significant effect of enhanced heat transfer. I am an expert from China Products, usually analyzes all kind of industries situation, such as energy efficient chest freezer , used ice cream carts.
