FRESH AIR AIR-CONDITIONER STRUCTURE 2293444
BACKGROUND OF THE INVENTION
The Exposure-Type working substance evaporator of the conventional airconditioner relates to blowing a wet gauze to cause evaporation of liquid under ambient temperature. ambient pressure and heat absorption of liquid due to evaporation may result in air cooling when blown out; because of containing high humidity. except for few dry areas. such kind of air blown out will be harmful to body health.
In addition the aforesaid conventional device has low efficiency due to little work performed.
Another type of conventional air-conditioner is mounted with a compressor for changing pressure of working substance (coolant) in a closed cycle pipe to cause working substance discharging heat and absorbing heat due to liquidation and evaporation; because such air-conditioner has involved in large waste of work. to save the waste of work a closed cycle air cooling is adopted for cyclic cooling through continuous absorbing indoor air and seldom for cooling through absorbing outside air (in general fan volume is 15% under) so indoor air will become dirty and less oxygenous turbidity and inadequate oxygen have become worsening.
SUMMARY OF THE INVENTION
The present invention relates to an air-conditioner structure for cooling air based on physical property of heat absorption by working substance evaporation on the evaporation film by means of guiding air flow.
The present invention relates to an improvement for the air-conditioner of exposure-type working substance. and particularly. a plurality of heat transmission plates are provided the housing body. one side of each plate has a evaporation surface and the other side of it has a heat-absorbed surface. Main improvements include:
1. a thin cabinet for installed between indoor and outdoor (such as window type) in order to absorb outdoor air while to discharge indoor air; according to such design high-oxygen outdoor air can be induced while indoor turbid air can be discharged; 2. a cassette heat transmission plate unit. such plate body may be arranged to form a duct on each side respectively for evaporation and heat absorbing; 3. a structure having large-evaporation surface and cooling surface to attain utmost depth and width; 4. on a cabinet to establish large flow ducts. and during each Process two non-exchangeable ducts are engaged in evaporation and heat discharge respectively to achieve high efficiency of heat transmission; 5. replaceable working substance container and filter can be incorporated.
The working substance mentioned herein may be clean water or solution containing small volume of non-toxic glycerol.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGs. 1 and 2. the present invention comprises a housing body 1 including fan guides 2, 2', two fans 3, 4. heat transmission plate 5 and working substance container 6.
Housing body 1 having a unit of air intake 11 and outlet 12, and a unit of suction Port 13 and exhaust Port 14; outdoor fresh air is induced by fan 3 for heat exchange through a specific duct (to be described later) from air intake 11 to heat transmission plate 5, fresh and cool air is thus guided out of the outlet 12; indoor air is induced by fan 4 for evaporation through a specific duct (to be described later) from suction port 13 to heat transmission plate 5 and is thus discharged from exhaust port 14.
The aforesaid intake is formed by induction by fan 3. separation by fan guide 2 and specific duct in heat transmission plate 5. The exhaust is formed by induction by fan 4. separation by fan guide 2' and specific duct in heat transmission plate 5.
The aforesaid intaken air and exhausted air respectively have a U shaped channel and an inverted U channel and they are not intermingled.
On the said intake 11 and suction port 13 having ai filter 15. 16 respectively.
Referring to FIG. 3 thru 6. said heat transmission plate 5 including frame body 51. U metal sheet 52. folding heat guide plate 53 and liquid discharge tube 54.
Frame body 51 resembles a flat structure including two column bodies 511, an upper separate plate 512 and lower separate plate 513; on said column body 511 having a proper number of pins 514. holes 515. fastening blocks 516. retaining holes 517. the match of pin 514 and fastening block 516 on each frame body 51 with hole 515 and retaining hole 517 in front of frame body 51 may form secure connection that may mount up a proper number of frame body 51 into a set of heat transmission plate 5.
U metal sheet 52 is mounted above the lower separate plate 513 of frame body 51. said U metal sheet 52 having folding heat conduct plate 53 therein; U metalsheet 52 is a good heat conductor having an opening 521 on the top and a closed port 522 on the bottom. on each external side of U metal sheet 52 having evaporation film 55 (to be described later). The width of U metal sheet 52 is fitted mounting on the side of frame body 51 (between column bodies 511) and the height is the same as the frame body 51.
The said folding heat conduct plate 53 is a folding type good conductor. with width as same as the width of U metal sheet 52. and thickness as same as inner thickness of U metal sheet 52. and height smaller than the internal height of U metal sheet 52 to make a space formed between the lower side of folding heat conduct plate 53 and sealing port 522 as a common diversion duct 56 for air flow.
A proper number of longitudinal ducts are formed between folding heat conduct plate 53 and U metal sheet 52 to provide quick temperature equilibrium between air and metal sheet 52 (heat exchange).
The portion above folding heat conduct Plate 53 and under fan guide 2 has divided folding heat conduct plate 53 into external portion 531 and internal portion 532 and either of ducts may be blocked up as needed.
Outdoor air (i.e. fresh air) is induced from the external duct 531 of folding heat conduct plate 53 to divert through diversion duct 56 for upward induced indoor through the internal duct 532 (refer to FIGs. 3, 5).
On the other side of frame body 51 and under the upper separate plate 512 has liquid discharge tube 54 for discharge of liquid working substance; a fixed beam 518 located between column bodies 511 and a proper number of upright separate plates 519 mounted thereon. the portion under said separate plates 519 is similar to which under frame body 51. rear side is firmly connected with lower separate plate 513; a certain spacing is kept between the portion above separate plate 519 and upper separate plate 512; each side of separate Plate 519 is connected to evaporation film 55 on the external side of U metal sheet 52; said mounting may enable each side of each separate plate 519 to form a duct so that diversion duct is formed between separate plate 519 and upper separate plate 512.
A plate is mounted between the Portion under the separate plate 519 and housing body (refer to FIG. 4) to divide the duct beside said separate plate 519 into internal and external sections.
Indoor air is induced from the suction Port 13, flowing upward to diversion duct through internal duct to divert through external duct for downward induced outdoor through the exhaust port 14.
The vaporizing film 55 is made of anti-corrosive. water absorbing, dishevelled. coarse, and eyelet cloth which is blanket-like and folded in single or multiple layers. like polyacrylic staple fiber.
When working substance (may be clean water) is discharged from liquid discharge tube 54. the aforesaid structure will moisturize the evaporation film 55 under each side of liquid discharge tube 54 and working substance will flow downward naturally due to gravity; when indoor air induced is passing by. evaporation is thus caused for absorbing heat from U metal sheet 52 due to its physical property. because of heat transmission U metal sheet 52 will absorb heat from folding heat conduct plate 53, and metal sheet 52 as well as folding heat conduct Plate 53 will extract heat from pass-by air induced from outdoor. The aforesaid heat exchange is conducted through respective U ducts for gradually cooling fresh air induced from outdoor.
Working substance container 6 is a device for loading working substance, including water valve 61. filter 62. water pan 63 and connected with a water pump 64 which can deliver working substance to liquid distribution tube 65 above heat transmission plate 5 at specific interval. liquid distribution tube 65 will deliver working substance to liquid discharge tube 54 to enable working substance to pass by evaporation film 55 of heat transmission plate 5 due to gravity. and gradually flowing downward return pan 63 and working substance container 6. and working substance in water pan 63 will be converged into working substance container 6.
On the housing body 1 outside working substance container 6 has a movable plate 66 for removing or inserting working substance container 6 therefrom, and the operation is as such: close water valve 61 to close the passage of working substance container 6 to water pump 64 so that the whole container 6 can be removed for washing clean.
