Abstract
The invention relates to a soft hard ripple sheet used in welding sheet heat exchanger or frame heat exchanger, wherein the invention comprises soft ripple, hard ripple, an unit soft hard ripple sheet formed by alternated soft and hard ripples; said units are layered to form soft hard ripple channel, to solve the problems of pressure decrease and heat transmission efficiency, with better thermal transmission property and fluid uniform distribution, to make two side flow channels both soft hard ripple channels. The invention can be used to realize pure-reverse heat exchange installment.
Description
Technical field
The invention belongs to field of heat exchangers, relate to a kind of soft and hard corrugated board structure that is used for welded plate type heat exchanger or lamella heat exchanger.
Background technology
At present, welded plate type heat exchanger is a kind of advanced person's in the world a heat exchanger structure form, it as heat transfer element, and replaces the rubber cushion sealing of common plate type heat exchanger in the welded seal mode with plate type heat exchanging element, has increased substantially the serviceability temperature and the bearing capacity of plate type heat exchanger.
But full welded plate formula heat exchanger corrugated cardboard sheet of the prior art is generally the plate of single soft wave runner formation or the plate that single hard corrugated channel constitutes, and can not finely take into account pressure drop and heat transfer efficiency; And for the side direction charging, its medium is prone to the dry plate phenomenons such as dead band that medium is not flowed through from uniform poor-performing.
Summary of the invention
The object of the present invention is to provide a kind of heat transfer property and fluid from the good heat exchanger soft and hard corrugated board structure of uniform performance.
The technical solution used in the present invention: a kind of soft and hard corrugated board structure, comprise soft wave or hard ripple, by soft wave, the synthetic soft or hard ripple unit of hard ripple alternate group, each plate comprises a plurality of soft or hard ripples unit.
Described soft wave and soft wave diagonal angle, hard ripple and hard ripple diagonal angle constitute rectangle soft or hard ripple unit.
Described soft wave and shell side MEDIA FLOW between angle be 0≤θ≤45 °, described hard ripple and plate journey MEDIA FLOW between angle be 45＜θ≤90 °.
Described soft wave, hard ripple are herringbone.
The described plate that comprises a plurality of soft or hard ripples unit, a plurality of groups of poststacks, its soft wave face with its on or the hard corrugated surface of another plate under it contact, hard corrugated surface with its on or the soft wave face of another plate under it contact, between plate and plate, all form soft or hard ripple combined flow channel, be that runner one side is a soft wave, opposite side is hard ripple.
The described plate that comprises a plurality of soft or hard ripples unit, a plurality of groups of poststacks, the shell side MEDIA FLOW is to being passed in and out by the plate side direction, plate journey MEDIA FLOW is to being passed in and out by the plate two ends, the shell side MEDIA FLOW to plate journey MEDIA FLOW to being pure adverse current in the plate both sides, the shell side MEDIA FLOW is fluid from uniform in runner between plate.
The present invention adopts soft wave, the synthetic cell cube plate of hard ripple alternate group, a plurality of cell cube plate groups poststacks all form the soft or hard corrugated channel between plate, rationally solve plate pressure drop and heat transfer efficiency matching problem, have good heat transfer property and fluid from uniform performance; Simultaneously can realize that plate two side runners are the soft or hard corrugated channel; The present invention is suitable for welded plate type heat exchanger, is mainly used in lamella heat exchanger and realizes that pure countercurrent flow installs and uses.

The specific embodiment
Consult Fig. 1, Fig. 2, shown in Figure 3, a kind of soft and hard corrugated board structure, by lambdoid soft wave 1, the synthetic cell cube soft and hard corrugated board sheet of hard ripple 2 alternate group, i.e. soft wave 1 and soft wave 1 diagonal angle, hard ripple 2 constitutes a rectangle soft and hard corrugated board structure with hard ripple 2 diagonal angles; Described soft wave 1 and shell side MEDIA FLOW angle between 3 is 0≤θ≤45 °; Described hard ripple 2 and plate journey MEDIA FLOW angle between 4 are 45＜θ≤90 °.
Consult shown in Figure 4, described soft wave 1, a plurality of groups of poststacks of rectangular element body plate that hard ripple 2 is alternately formed, 1 of its soft wave with its on or hard ripple 2 faces of another cell cube plate under it contact, hard corrugated surface 2 with its on or soft wave 1 face of another cell cube plate under it contact, between cell cube plate and cell cube plate, all form soft or hard ripple combined flow channel, be that runner one side is a soft wave, opposite side is hard ripple, its heat transfer property is better than single soft wave runner, and the resistance drop performance is better than single hard corrugated channel, rationally solve plate pressure drop and heat transfer efficiency matching problem, had good heat transfer property.
Described a plurality of cell cube soft and hard corrugated board sheet group poststack, the shell side MEDIA FLOW is passed in and out by the plate side direction to 3, plate journey MEDIA FLOW is passed in and out by the plate two ends to 4, and the shell side MEDIA FLOW is pure adverse current to 4 in the plate both sides with plate journey MEDIA FLOW to 3, and the shell side MEDIA FLOW is fluid from uniform to 3 in the runner between plate.
