background technology:
Along with the development of modern science technology, all need heat exchanger from petro chemical industry to universe industry, of a great variety due to heat exchanger, carry out classification according to the shape of its heat-transfer area and structure and can be divided into cast, template and other pattern heat exchangers.And tube type heat exchangers can be divided into coil heat exchanger, double pipe heat exchanger, shell-and-tube; Plate type regenerator can be divided into spiral heat exchanger, plate type heat exchanger, lamella heat exchanger and plate-fin heat exchanger.The heat transmission equipment of the advantage that plate-fin heat exchanger is a kind of compact conformation, quality is light, heat transfer efficiency is high and good economy performance etc. is given prominence to, be separated at the cryogenic separation of separation and liquefaction, the ethene of Aero-Space, refrigeration air-conditioner, air separation, oil gas field, synthetic ammonia tailgas, the field such as dynamic power machine, natural gas, atomic energy obtain applying more and more widely, and utilizing heat energy, recovery waste heat, economize in raw materials, to reduce costs etc. in achieve significant economic benefit.Plate-fin heat exchanger is by taking over, end socket, the compositions such as heat exchange core body, heat exchange core body is made up of some basic flow passage units and end plate, basic flow passage unit is by heat exchange fin, flow deflector, dividing plate and strip of paper used for sealing composition, several such flow passage units are integral according to the stacked soldering of fluid-flow mode, cold fluid and hot fluid flow in adjacent basic flow passage unit, heat exchange is carried out by heat exchange fin and with dividing plate, heat exchange fin is the minimum unit of plate-fin heat exchanger, heat exchange major part between cold fluid and hot fluid passes through thermofin, fraction is directly undertaken by dividing plate.In normal design, heat exchange fin heat transfer area is approximately 67% ~ 88% of heat exchanger total heat conduction area, connection between thermofin and dividing plate is perfect soldering, therefore most of heat passes to heat exchange fin, cold fluid is passed to by dividing plate by heat exchange fin, due to heat transfer direct heat transfer unlike dividing plate of heat exchange fin, therefore heat exchange fin has again the title on " secondary surface ", and secondary heat-transfer area is generally low than the heat transfer efficiency of a heat-transfer area.The type of heat exchange fin and physical dimension are the key factors affecting heat exchanger performance, conventional heat exchange fin has the structural shapes such as plain fin, saw tooth fin, perforated fin, corrugated fin, from heat-transfer effect aspect, heat exchange fin is that enhanced heat exchange is carried out in the disturbance of the development and reinforcement fluid utilizing the discontinuity of geometry to destroy flow boundary layer air, is favourable to raising heat transfer effect.
summary of the invention:
The task of the utility model patent is to provide a kind of plate-fin heat exchanger, do not changing the physical dimension of the processing technology of existing thermofin, process equipment and fin, adopt Novel heat transfer fin, not only increase the heat transfer efficiency of thermofin, and make the structure of plate-fin heat exchanger compacter.
The technical solution of the utility model is: existing plate-fin heat exchanger be processing technology and structure constant when, change existing heat exchange fin into novel heat exchange fin, this fin combines corrugated fin, the feature of perforated fin and saw tooth fin, the wing height surface of corrugated fin is beaten the aperture that gathers and along finned length direction being cut into many short and small fragments and stagger mutually certain intervals and the zigzag porous ripple fin of discontinuous that formed, existing corrugated fin is replaced with this heat exchange fin, when heat exchanging fluid flows in runner, sawtooth and porous shape serve the effect of enhanced heat exchange, the heat transfer efficiency of heat exchange fin is increased,
Zigzag porous ripple type plate-fin heat exchanger, by heat exchange core body, end socket and fluid inlet and outlet adapter composition, heat exchange core body is made up of the end plate 7 of some basic flow passage units and both sides, each basic flow passage unit is by heat exchange fin, flow deflector, dividing plate and strip of paper used for sealing composition, the wing height surface of corrugated fin is beaten the aperture that gathers and along finned length direction being cut into many short and small fragments and stagger mutually certain intervals and the zigzag porous ripple fin of discontinuous that formed, the stacked soldering of several such flow passage units is become zigzag porous ripple type plate-fin heat exchanger, cold fluid and hot fluid flow in adjacent basic flow passage unit, heat exchange is carried out by zigzag porous ripple heat exchange fin and dividing plate.
The utility model has following beneficial effect: owing to adopting technique scheme, achieve and utilize novel saw-tooth porous ripple fin to form plate-fin heat exchanger, it is enhanced heat exchange effect not only, improves the heat transfer efficiency of heat exchange fin, and makes the structure of plate-fin heat exchanger compacter.
