The utility model improves heat exchange efficiency, and allows the cold fluid outlet temperature to approximate the hot fluid inlet temperature; the hot fluid outlet temperature approximates the cold fluid inlet temperature, and simultaneously, holes on the heat exchange element form a common rib effect, thereby saving metal materials, space and energy, and increasing the heat transfer area; and the round hole structure and the adjacent holes form arch-shaped structures, thereby realizing high pressure resistance so as to expand the application field.
Description
Technical field
The utility model relates to a kind of a kind of heat transmission equipment that relates to, specifically a kind of pore plate cascade type heat exchange device.
Background technology
Existing dividing wall type heat exchanger can be divided into pipe heat exchanger, plate type heat exchanger, double pipe heat exchanger and shell-and-tube heat exchanger etc. according to the structure difference of heat-transfer area; Wherein the heat exchange area of plate type heat exchanger is big, heat exchange property good, but there is following shortcoming in existing plate type heat exchanger: (1) existing plate type heat exchanger to return heat loss big, this is because according to the heat exchange principle, as long as enough heat-exchange times and heat exchange process are arranged, it is equal that the temperature of cold and hot two kinds of heat exchanging fluids finally can be tending towards; Existing its cold fluid outlet temperature of various countercurrent flow equipment can only be higher than the hot fluid outlet temperature, but can not wherein have a big chunk heat energy to lose near the hot fluid inlet temperature, has influenced the further raising of heat exchange efficiency; (2) rib effect altogether: promptly existingly board-likely can not make heating between two plates and have influence on that other plate gets on; (3) can't be high pressure resistant, limited its application.
The utility model content
The purpose of this utility model is to overcome the shortcoming of existing plate type heat exchanger, and a kind of pore plate cascade type heat exchanger is provided.To realize improving heat exchange efficiency, make heat exchange efficiency approach optimal degree; Also metal material, conserve space be can save, its heat exchange area, energy savings in limited heat exchange volume, increased.
The technical solution of the utility model is: comprise heat exchange element, the cold fluid and hot fluid clutch at heat exchange element two ends, reverse cold fluid import and export and the hot fluid import and export that is arranged on cold fluid and hot fluid clutch two ends, each other be connected and fixed part; It is characterized in that, described heat exchange element is by some porous plates and shape size sealing heat insulating mattress or the fluid sealant alternate orifice-plate type heat exchange element that be formed by stacking identical with it, described porous plate is be staggered side by side on each sheet porous plate several rows cold water through hole and hot water through hole, be provided with the water conservancy diversion frid between orifice-plate type heat exchange element and cold fluid and hot fluid clutch, described water conservancy diversion frid is submitted wrong parallel arranged several rows thermal conductance chute and cold guiding gutter.
The quantity of described heat exchange element is 5～200.
Have the hot fluid through hole above the described thermal conductance chute.
Have the cold fluid through hole above the described cold guiding gutter.
Line-spacing between the pitch-row of described cold water through hole and hot water through hole, aperture and cold water through hole and the hot water through hole is according to the difference of the heat exchanger of different model size and difference.
Advantage of the present invention: advantage of the present invention: the alternate stack of (1) sealing heat insulating mattress with porous plate, the porous plate heat exchange element between each sheet can be separated, can play sealing function.So both improved horizontal heat exchange efficiency (being the heat exchange between cold fluid and hot fluid); Can prevent that again vertically (being on the flow direction) conducts heat; Can stop hot-fluid to spread to cold junction, make the heat exchange effect approach optimal degree, promptly the cold fluid outlet temperature can be approached the hot fluid inlet temperature; And the hot fluid outlet temperature can be approached the cold fluid inlet temperature, makes heat exchange efficiency reach desirable level; (2) formed common rib effect between the hole on the heat exchange element: the heating of one of them hole can the whole orifice plate of influence other hole, this can not only save metal material, conserve space, in limited heat exchange volume, increase heat exchange area, and saved the energy, improved heat exchange efficiency.This is that other any heat exchanger institute is irrealizable; (3) this borehole structure and its adjacent holes form domes each other, can bear big pressure; Thereby realized high pressure resistantly, can enlarge its application.
