Abstract
Abstract A cooling device for an enclosure, specifically parked automotive vehicles, mountable in a window comprising an air channel for introducing normally cool ambient air from outside the vehicle into the vehicle passenger compartment. The atmospheric air channel is positioned so as to cause the ambient air to be forced to the bottom of the vehicle compartment. This introduction of new atmospheric air increases the internal pressure of the vehicle compartment causing the interior air to seek escape by the easiest means possible, such as, the open portion of the window surrounding the inlet of the device. Additionally during days of cooler ambient temperatures the device has a heating member (52) such that it can perform area heating. Further a coanda nozzle (16) is attached to the outlet (14) of the air channel which acts to speed the velocity of the air being forced to the bottom of the vehicle. This increase in air velocity is then utilized to impart some of its energy to the still air at the outside exit of the nozzle thereby increasing the overall exhaust air flow.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
166 words
An apparatus for ventilation and heating of passenger vehicle enclosure, at least one window for an atmospheric air passageway, said apparatus comprising: a. an air channel having an air passageway therethrough and an intake aligned at approximately 90 degrees to said channel and an outlet nozzle at the distal end of said passageway, said air channel being detachably mountable to a nearly fully raised enclosure window top by intake hook means at an opening over said window of said enclosure to be ventilated; b. a fan mounted in a lengthways center of said air channel to force air through said air channel and through said outlet nozzle to a lower most portion of said enclosure; c. a heat sinking structure mounted at an atmospheric air exhaust of said fan, a heating member being mounted in the core of said heat sinking structure to cause normally sensible heat to be sunk by said heat sinking structure, said outlet nozzle being positioned downstream from said heat sinking structure.
Claim 2
Independent Claim
166 words
An apparatus for ventilation and heating of passenger vehicle enclosure, at least one window for an atmospheric air passageway, said apparatus comprising: a. an air channel having an air passageway therethrough and an intake aligned at approximately 90 degrees to said channel and an outlet nozzle at the distal end of said passageway, said air channel being detachably mountable to a nearly fully raised enclosure window top by intake hook means at an opening over said window of said enclosure to be ventilated; b. a fan mounted in a lengthways center of said air channel to force air through said air channel and through said outlet nozzle to a lower most portion of said enclosure; c. a heat sinking structure mounted at an atmospheric air exhaust of said fan, a heating member being mounted in the core of said heat sinking structure to cause normally sensible heat to be sunk by said heat sinking structure, said outlet nozzle being positioned downstream from said heat sinking structure.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein said outlet nozzle comprises a dual cone nozzle restriction centered in said outlet nozzle, said dual cone nozzle restriction maintaining an annular outlet around one cone perimeter.
Claim 4
Dependent Claim
67 words
The apparatus of claim 1 wherein said outlet nozzle includes: a diameter reducing nozzle comprising: a dual cone nozzle restriction; and spacer means to center said dual cone nozzle restriction in an outlet of said diameter reducing nozzle such that said dual cone nozzle restriction creates a thin annular exit for exhaust air around a perimeter of a lower most cone of said dual cone nozzle restriction.
Claim 5
Dependent Claim
45 words
Apparatus of claim 1 wherein said fan includes: a delay control circuit board; and an on/off delay knob; said fan having said on/off delay knob as a control means for said delay control circuit board such that said fans can be controlled by delayed time.
Claim 6
Dependent Claim
23 words
Apparatus of claim 1 wherein said intake hook means comprises: an intake approximately 1/8 to 1/2 inches high and approximately 4 inches wide.
Claim 7
Dependent Claim
31 words
The apparatus of claim 1 wherein said intake hook means is covered around its width in a resilient foam such that said window of said enclosure is protected against glass chipping.
Claim 8
Dependent Claim
28 words
The apparatus of claim 6 wherein said intake hook means has a small portal means for providing an air freshener to atmospheric air within said intake hook means.
Claim 9
Dependent Claim
41 words
The apparatus of claim 7 wherein said intake hook means has an absorbent foam seat mounted internal to said intake hook means and aligned with said portal means to retain said air freshener and absorb any moisture that enters the intake.
Claim 10
Dependent Claim
13 words
The apparatus of claim 1 wherein said fan comprises an axial blowing fan.
Claim 11
Dependent Claim
20 words
The apparatus of claim 1 wherein said air channel is composed of a material that absorbs very little radiant heat.
Claim 12
Dependent Claim
12 words
The apparatus of claim 10 wherein said material is white in color.
Claim 13
Dependent Claim
21 words
The apparatus of claim 1 wherein said air channel is composed of a plastic material that can withstand various temperatures extremes.
Claim 14
Dependent Claim
14 words
The apparatus of claim 1 wherein said heat sinking structure is composed of aluminum.
Claim 15
Dependent Claim
10 words
The apparatus of claim 13 wherein said aluminum is porous.
