Description

DETAILED DESCRIPTION OF THE FIGURES

(1) FIG. 1 shows a first embodiment of a non-powered cooling device 1 comprising a funnel unit 10 with a large opening 11 showing from the device bottom, small opening 12 as the top and optional high heat capacitance units 60 arranged inside. The large opening features spacers 30 and air openings 31 for air intake, with adhesive 40 on some or all spacers for adhesion of the funnel unit to an underlying surface (not pictured).

(2) FIG. 2 shows an alternate embodiment of the device of FIG. 1, wherein a plurality of funnel units are attached to a single latticework base 20 along the top of an interior window sill. The base 20 comprises a plurality of pairs of base struts 21 raised vertically from a window sill, each such pair of struts connected by a rigid base connector 23. Each pair of struts 21 is connected to one another by two or more of flexible base connectors 23 overlaying the sill, and each set of struts is further interspersed with and connected to funnel units 10 by a plurality of flexible base-funnel connectors 24, wherein such flexible base-funnel connectors adhered or tied to the top of each strut and around each funnel unit. Each funnel unit is thus allowed to hang freely above the sill surface without touching it. This embodiment may also be employed on any horizontal surface, including but not limited to tabletops and countertops.

(3) FIG. 3 shows a cutaway view of the cooling device embodiment of FIG. 2, wherein the bottle-shaped funnel unit 10 is overlaid with a layer of packing material 70, and further overlaid by a dark cover 50, such as neoprene material.

(4) FIG. 4 shows plurality of funnel units 10, with the small openings 12 of the funnel units 10 pointing upward for air cooling. In this iteration, multiple funnel units 10 are adhered to the inner surface of shell 70 in a stairstep pattern to avoid one unit expelling cooled air from its small opening 12 directly into the large opening 11 intake of another unit. A row of optional high heat capacitance units 60 are visible circumnavigating each large opening to aid in room air intake. Various patterns of staggering units are available to maximize the user of internal surface area of the shell while avoiding cross-ventilation between units.

(5) FIG. 5 shows the inner wall 15 of a funnel unit 10 comprising a ridged and beaded morphology. As shown, a plurality of raised ridges 61 run from the large opening 11 to the small opening 12 of the funnel unit, thus channeling the air running through the unit between such ridges. In this embodiment, a plurality of beads 62 are further arranged in the spaces between the raised ridges, thereby creating additional turbulence in the channeled air and thus increasing convection cooling. While the embodiment pictured shows a regularity to the placement of ridges and beads around the inner surface, such regularity is not required, and placement of the beads and ridges may appear in a multitude of patterns or haphazardly. Another embodiment may also comprise beads only or ridges only, as neither feature requires the presence of the other. Ridges and beads may optionally be formed from high capacitance materials.

(6) FIG. 6 shows a cross-section of a funnel unit 10 wall comprising the ridges 61 and beads 62 as pictured in FIG. 5, wherein the ridges are shaped roughly as tapered hillocks while the beads are shaped as semicircular studs. In other embodiments, the shape of the ridges and beads may be more squared or conform to alternate shaping to further maximize convection.
