Abstract
The invention provides a sawtooth porous type plate-fin heat exchanger. The existing plate-fin heat exchanger is formed by heat exchange fins, a baffle, a seal strip, a flow deflector, an end plate, an end socket, a liquid inlet and outlet connection pipe and the like. Under the condition that the existing structure is not changed, the characteristics of porous fins and sawtooth fins are combined, many short fragments are cut in the teeth length direction of the porous fin, and sawtooth shapes are staggered at intervals in the teeth length direction of the porous fin to obtain the sawtooth porous type fins. When heat exchange fluid flows in a runner, the sawtooth facilitates fluid disturbance, the heat exchange function is strengthened, and the heat exchange efficiency of the heat exchange fin is improved. By adopting the technical scheme, the plate-fin heat exchanger is formed by porous sawtooth fins; the heat exchange effect is strengthened; the heat exchange efficiency of the heat exchange fin is improved, and the structure of the plate-fin heat exchanger is more compact.
Description
technical field:
The present invention relates to technical field of heat exchangers, specifically a kind of zigzag porous type plate-fin heat exchanger.
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 taken over by fluid inlet and outlet, 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 heat exchange fin, 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 heat exchange fin 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, perforated fin, perforated 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 patent of the present invention is to provide a kind of plate-fin heat exchanger, do not changing the physical dimension of the processing technology of existing heat exchange fin, process equipment and fin, adopt novel heat exchange fin, not only increase the heat transfer efficiency of heat exchange fin, and make the structure of plate-fin heat exchanger compacter.
Technical scheme of the present invention is: existing plate-fin heat exchanger processing technology and structure constant when, change existing heat exchange fin into novel heat exchange fin, this fin is in conjunction with the feature of perforated fin and saw tooth fin, the tine length direction of perforated fin is cut into many short and small fragments and stagger mutually certain intervals and the zigzag fashion that formed, obtain a kind of zigzag perforated fin with saw tooth fin design feature, existing perforated fin is replaced with this heat exchange fin, when heat exchanging fluid flows in runner, saw tooth fin serves the effect of enhanced heat exchange, the heat transfer efficiency of heat exchange fin is increased,
Zigzag porous type plate-fin heat exchanger, comprise heat exchange core body, end socket and fluid inlet and outlet adapter etc., heat exchange core body is made up of some basic flow passage units and end plate, each basic flow passage unit is by heat exchange fin, flow deflector, dividing plate and strip of paper used for sealing form, the tine length direction of perforated fin is cut into many short and small fragments and stagger mutually certain intervals and the zigzag fashion that formed, obtain a kind of zigzag perforated fin with saw tooth fin design feature, many so stacked solderings of element of fluid are become zigzag porous 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 heat transfer fin and dividing plate.
The present invention has following beneficial effect: owing to adopting technique scheme, achieve and utilize zigzag perforated 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.
