Description

Reverse-flow air-the air heat regenerator of corrugated plating

Technical field

The utility model relates to air heat regenerator, the reverse-flow air-air heat regenerator of specifically a kind of corrugated plating.

Background technology

Along with economic development, living standards of the people improve, the factory of modern architecture, commercial building, hotel, office and household are to satisfy the requirement of comfortableness and manufacturability aspect, have generally used the air-conditioning system that can regulate temperature, humidity and add new wind for the raising indoor air quality.And along with people and some industry require more and more highlyer to indoor air quality, must require air-conditioning system to improve new wind ratio, strengthen resh air requirement, new wind load will be very big thus.Reduce the new wind load purpose of energy saving in order to reach, air-conditioning system has generally been used the air-air heat regenerator that can reclaim cold and hot energy from combustion gas.

The at present domestic heat regenerator that generally uses mostly is plate wing partition cross flow, its weak point: 1. it is little to cross flow diameter, and running resistance is big.2. the heat exchange mean logarithmic temperature difference is low, and turbulence level is low, and compact degree is low and limited by raw material, and heat transfer process length is low, so its heat recovery efficiency is low.3. air current composition form that can only the heteropleural distributary is installed and used it and is restricted.

Therefore, prior art has improvement, perfect necessity, increases new kind.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of improved corrugated plating reverse-flow air-air heat regenerator, under the condition that does not increase the heat regenerator manufacturing cost, reach the high heat recovery efficiency of user to heat regenerator, low running resistance, easily heat recovery efficiency and running resistance are mated, the requirement of easily installing in system, use, safeguarding.

The purpose of this utility model is achieved in that

Reverse-flow air-the air heat regenerator of a kind of corrugated plating mainly is made up of heat exchanger plates, shell, it is characterized in that:

Described heat exchanger plates is formed by stacking by multi-disc ripple heat exchanger fin, the two-way drawbead that respectively is suppressed with horizontal indent at the crest and the trough of each ripple heat exchanger fin, the supporting of this drawbead is superimposed ripple heat exchanger fin and form the current path of gap-shaped between adjacent two mutually, and each heat exchanger fin is packed in the shell.

Regular and/or the irregular chill mark in described ripple heat exchanger fin surface.

The outline of described heat exchanger plates is octagon.

The height of the gap-shaped current path that described adjacent heat exchanger fin is formed by the supporting of self drawbead is between 1-3mm.

The current path of the gap-shaped that described fin is overlapped into is that homonymy is reverse-flow, and its new wind OA is communicated with the air-supply SA in the lower left corner from the lower right corner, and the return air RA in the upper left corner is communicated with the air draft EA in the upper right corner.

The current path of the gap-shaped that described fin is overlapped into is that heteropleural is reverse-flow, and its new wind OA is communicated with the air-supply SA in the lower left corner across from the upper right corner, and return air RA is communicated with the air draft EA in the lower right corner across from the upper left corner.

The securing structure of described heat exchanger fin and shell can be in being connected any of bonding, welding, undercut.

The utility model has following actively useful effect:

Judge that the heat regenerator quality mainly contains four performance indications: 1. heat recovery efficiency, its value is high more, and performance is good more.2. running resistance, its value is low more good more.3. compactness, its value is high more good more.4. slip, its value is low more good more.

The utility model heat regenerator has realized having improved heat recovery efficiency by adopting following technical measures, reduces running resistance, the function that increases compactness and reduce to leak.

1. heat exchanger fin is made whole corrugated plating, the wrinkleization surface, two-way lacing wire improves the heat exchange overall heat-transfer coefficient, and its measured value is 1.2-1.3 a times of plate wing cross flow heat regenerator, expanded the heat exchange gross area simultaneously, with plate wing cross flow heat regenerator on year-on-year basis under the condition heat exchange gross area expanded 15%-25%.Therefore the utility model technology has higher heat recovery efficiency than plate wing cross flow.

2. plate length (heat recycle process length) is not subjected to material roll tolerance system, and plate wing cross flow is limited by the raw material amplitude, and maximum plate length (heat recycle process length) is the raw material fabric width, is about 400mm.Therefore the utility model can obtain higher, more manageable heat recovery efficiency.

3. whole counter-flow heat exchange can access than the higher mean logarithmic temperature difference of plate wing cross flow heat exchange, therefore higher and faster energy transmission is arranged, and its heat recovery efficiency is higher.

4. heat exchanger fin is by self drawbead support formation gap-shaped overcurrent loop, and its running resistance is lower, is the 30%-40% of plate wing cross flow heat regenerator.

5. two kinds of air flow paths of homonymy adverse current and heteropleural adverse current, the mounting, commissioning and maintenance of more convenient system.

6. the shaping degree of depth of control heat exchanger fin ripple and drawbead can conveniently be adjusted the overcurrent passage in height, promptly adjusts running resistance.

7. the bonding heat exchanger fin of PUR forms current path, has greatly reduced slip, and under the utility model operate as normal, the actual measurement slip is 2-3%, is lower than the universal standard 5%, is lower than the 6-7% of plate of the same trade.

In sum, the utility model heat regenerator heat exchanger fin, support to the overcurrent wind path by corrugated plating, wrinkleization surface, drawbead, eight limit outlines and heat exchanger fin self, the overall structure mode of homonymy adverse current, heteropleural adverse current, effectively overcome the above-mentioned shortcoming of cross flow heat regenerator, be the best regeneration product of cross flow heat regenerator, leading heat regenerator market from now on.
