Description
Technical field
The utility model relates to the ventilation field, particularly, relates to a kind of air heat regenerator heat exchange core.
Background technology
As far back as 1996, German lung company developed first fresh air ventilator in the world, and formally imports China in 2000, through updating and innovating, has been widely used in the ventilation field at present.
In the prior art, air heat regenerator improves equipment as fresh air ventilator, can reclaim the energy that is run off in indoor dirty wind and the outdoor new wind exchange process better when fresh air ventilator is worked.Particularly, when fresh air ventilator is worked, indoor dirty wind is discharged to outdoor, simultaneously outdoor new wind is delivered to indoorly, carry out equivalent displacement between the two.
With regard to northern area, in summer, indoor temperature generally is lower than outdoor temperature; In the winter time, indoor temperature is higher than outdoor temperature.When indoor dirty wind and outdoor new wind being carried out the equivalent displacement, suppose not establish the energy recycle device of similar air heat regenerator, so, summer, indoor cold will be lost with the displacement of air, winter, therefore indoor heat also can run off, and had so just increased the load of refrigeration and heating equipment greatly, thereby had caused very big waste, as waste of electric energy, the shortening of service life of equipment etc.
In order to slow down above-mentioned waste of electric energy and the situations such as shortening of equipment operating period, so in fresh air ventilator, set up air heat regenerator; Wherein, energy losing issue when air heat regenerator can correspondingly solve above-mentioned indoor and outdoor ventilation, during fresh air ventilator work, indoor dirty wind and outdoor new wind pass through air heat regenerator simultaneously, heat-conduction effect by special substance, the energy that runs off is sent into indoor by outdoor new wind, just can be reached energy-conservation effect.
In the prior art, the material by the heat exchange core can be divided into air heat regenerator the full heat regenerator made of paper and the sensible heat recover of aluminum.
For above-described air heat regenerator, in realizing process of the present utility model, the inventor finds the sensible heat recover of air heat regenerator of the prior art, especially aluminum, has following defective at least:
(1) in the sensible heat recover of aluminum, the aluminium foil of selecting for use is that thickness is 0.05 millimeter normal aluminium foil, can not stretch, and after being made into a plurality of little airflow passages, the heat exchange area of original aluminium foil is reduced;
(2) in above-mentioned air heat regenerator, the cross section of each little airflow passage is isosceles triangle, and is too narrow, and the circulation to air causes very big resistance even obstruction easily; Simultaneously, can reduce integral device, promptly the running efficiency of the fresh air ventilator of this air heat regenerator is installed, also can shorten the service life of this fresh air ventilator;
(3) gas channel in above-mentioned air heat regenerator inside is smooth shape, and heat recovery efficiency is lower;
(4) in above-mentioned air heat regenerator, between new wind passage and the dirty wind passage, adopt gluing flats to isolate, when inhomogeneous, then be easy to occur the phenomenon that new wind mixes with dirty wind as if the latex of bonding place.
Summary of the invention
The purpose of this utility model is, at the problems referred to above, proposes a kind of air heat regenerator heat exchange core, to realize that heat exchange area is big, the running efficiency height of integral device, long service life, heat recovery efficiency height, and the advantage of the good airproof performance between new wind passage and the dirty wind passage.
For achieving the above object, the technical solution adopted in the utility model is: a kind of air heat regenerator heat exchange core comprises shell, and is installed in the heat exchange unit in the described shell that described heat exchange unit comprises the parallel a plurality of heat exchanger fins that overlay in the described shell; Each heat exchanger fin comprises that cross sectional shape is the heat transfer zone of concavo-convex alternate isosceles trapezoid, and the sealing strip that is positioned at described heat transfer zone periphery.
Further, described heat exchanger fin adopts heat treatment after " O " state stretches and thickness is the rectangle aluminium foil of 0.1-0.12mm, is stamped to form through mould; Wherein: through the zone of described mould punching press is heat transfer zone, is sealing strip without the zone of described mould punching press; Described heat transfer zone comprises that cross sectional shape is a plurality of gas channels of isosceles trapezoid, the concavo-convex alternate setting of described a plurality of gas channels.
Further, in described a plurality of gas channels, in the interior outside of each gas channel, being evenly equipped with diameter is a plurality of little round pool of 1-3mm.
Further, in described a plurality of heat exchanger fins, the gas channel antarafacial of adjacent two heat exchanger fins vertically is provided with.
Further, in described a plurality of heat exchanger fins, the bonding sealing-in of corresponding sealing strip flange seaming of a pair of sealing strip of each heat exchanger fin and an adjacent heat exchanger fin forms new wind passage or dirty wind passage; Another forms dirty wind passage or new wind passage to the bonding sealing-in of corresponding sealing strip flange seaming of sealing strip and another adjacent heat exchanger fin.
The air heat regenerator heat exchange core of each embodiment of the utility model, owing to comprise shell, and be installed in the heat exchange unit in the shell, heat exchange unit comprises the parallel a plurality of heat exchanger fins that overlay in the shell; Heat exchanger fin comprises that cross sectional shape is the heat transfer zone of concavo-convex alternate isosceles trapezoid, and the sealing strip that is positioned at the heat transfer zone periphery; Adopting " O " state stretching after heat treatment and thickness is the aluminium foil of 0.1-0.12mm, through the cross section is that the alternate mould of isosceles trapezoid convex-concave is stamped to form heat exchanger fin up and down, heat exchange area is bigger, the cross section of each gas channel is an isosceles trapezoid, near semicircle, the gas channel broad can reduce gas-flow resistance, be not easy to stop up, help improving the running efficiency of heat regenerator; Here, the internal structure and the heat exchange material of air heat regenerator heat exchange core are improved, air moment is detained and produces eddy flow, the ordinary hot recover in compared to existing technology, organic efficiency is higher; Thereby it is little to overcome in the prior art heat exchange area, and the running efficiency of integral device is low, service life short, and heat recovery efficiency is low, and the defective of the sealing difference between new wind passage and the dirty wind passage; To realize that heat exchange area is big, the running efficiency height of integral device, long service life, heat recovery efficiency height, and the advantage of the good airproof performance between new wind passage and the dirty wind passage.
