Kar-Kool

This device is used to keep a motor vehicle cabin cool when parked in a hot sunny day. It uses the latent heat of vaporization of a liquid such as water, combined with convection via forced air circulation. A second use for this device is to cool occupant(s) while vehicle is in transit by placing mist in front of built-in blowers in the dash of vehicle.

By November of 1992, "do-it-yourselfers" will no longer be able to charge their vehicles with chlorofluorocarbon based refrigerants. By 1995, chlorofluorocarbon based refrigerants will be banned for automotive use per the Clean Air Act. Owners will have to switch to a substitute which would require major alterations in chlorofluorocarbon based vehicle air conditioning system such as changing the compressor, metering device, etc. As a cost efficient alternative, "Kar-Kool" might be considered as it uses a coolant that does not pollute the environment, nor does it require major alterations. It has an added advantage in that "Kar-Kool" will keep the car cool while parked in the sun which present day air conditioners can't do. Further advantages offered by this device are: negligible gasoline consumption; less pollution due to the fact that gasoline is not combusted while vehicle is in parked position, and minimal gasoline is combusted while vehicle is in transit--the fuel consumption arising from the vehicle carrying the weight of "Kar-Kool"; lower maintenance cost, as one doesn't have to go to an EPA certified mechanic to recharge the air conditioning system; emergency water supply, in case of an overheated radiator, or being stranded in the desert, low capitol costs in manufacturing, and simplicity when compared to present day air conditioners.

The above and other objects are attained in an automobile through the utilization of combining water mist in front of a forced convection generator. Misting is accomplished by power from solar cells or vehicle battery or air pressure via bladder tank or a combination thereof, and forced convection generator. When vehicle is in transit, place atomizer in front of built-in blowers in the dash of vehicle; when vehicle is parked, place atomizer in front of window mounted fans. The water reservoir may be placed in the trunk or passenger compartment of motor vehicle. The power for the window mounted fans is solar energy, or vehicle battery. An intrusion prevention shroud which comprises of a plurality of adjustable geometric pieces connected by wire with plastic sheet attached to adjustable geometric pieces is used to fill in the gap created between the window and window frame by forced convection generator.

It is an object of this invention to provide cooling of automotive interior while in transit, or parked in the sun.

It is another object of this invention to provide cooling using environmentally safe methodology.

The cooler for automotive use in accordance with the present invention will hereunder be described with reference to the embodiments illustrated in the accompanying drawings.

FIG. 1 shows the cooling system installed in a vehicle 16 where the water reservoir 9 is shown in the back seat area, and the fans 15 located in between window and window frame, and adjustable geometric pieces 18 which prevent entry into vehicle by intruder.

FIG. 2 shows reservoir 9 comprising of an atomizer 1, a tube 2, double-sided clip 3 to hold the tube to a "pinchable" surface, valve 17 to discharge water through the atomizer 1, a water hose attachment 4, filtration 32 and chemical treatment 33 for inlet water, and accompanying valve 12, a diaphragm 5 to separate air from water, a pump 6, cubical 7 and cylindrical 8 cavities in the reservoir for holding miscellaneous items, a power cord 10 which is used to power the pump 6, where the power comes from solar cells, or vehicle electrical system, legs 11, and air inlet 13.

The automotive cooler described is operated in the following manner. Place the reservoir 9, in the trunk or luggage compartment of the vehicle, or in the back seat passenger compartment area, charge reservoir with water from a garden hose by screwing it into the female adaptor 4. Place fans 15 and accompanying intrusion prevention shroud(adjustable geometric pieces 18 connected by wire 14--FIG. 3--all of which are covered by plastic sheet 23--FIG. 4) in between window and window frame. While the vehicle is parked, insert receptacle cord 30 into a receptor connected to solar cells 41, or vehicle electrical system 40, turn on valve 17 which will atomize water, and place atomizer 1 in front of fans by attaching clip 3 to automobile interior(i.e. seat belt, seats, or any "pinchable area") such that spraying is occurring in front of the fans 15.

When the vehicle is in motion, in order to cool the driver, place the atomizer 1 in front of the built-in blowers by attaching double-edged clip 3 to the dash and the tube 2 which carries water to the atomizer. The forced convection from vehicle blowers combined with water spray has a cooling effect.

FIG. 3 shows the intrusion prevention device, a combination of wire 14, adjustable geometric pieces 18, and sheet 23 (see FIG. 4) where adjustable geometric blocks are held together by wire 14. FIG. 4 shows fans 15, a sheet 23 which covers the plurality of adjustable geometric pieces 18 and wire 14, all of which are secured between window 19 and window frame 24.

A detailed view of one of the adjustable geometric pieces 18 is shown in FIG. 5. These adjustable geometric pieces comprise of two smaller geometric pieces 20 with a slot, held together by a wing nut 21. Each geometric piece has a "wire threader" 22 through which wire 14 (seen in FIGS. 3 and 4) can be threaded to hold together the geometric pieces to form a skeleton of the intrusion prevention device. The bottom portion of the geometric piece has a "U" shaped channel 25 which is used to hold the geometric piece on to the window of the vehicle 16(seen in FIG. 1).

FIG. 6 shows fans 15(also seen in FIGS. 1, 3, and 4) housed in a triangular housing 26, with a cigarette lighter plug 30 for power, "U" shaped channel 27 for mounting on vehicle window, and air filter 29.

As an alternative to the type of tank depicted in FIG. 2, a bladder tank is shown in FIG. 7. Water is charged through port 36, chemically treated 33, filtered 32, and when fully charged, valve 31 is placed in the closed position. Water is discharged for the purposes of atomizing by opening valve 39 and passing through filter 32 to atomizer 34.
