DETAILED DESCRIPTION OF THE INVENTION

[0015] Referring now to the drawings and in particular FIGS. 1 and 2, a temperature modulation assembly 100 for a motor vehicle's passenger compartment is shown having an assembly panel 110 and an assembly housing 120. The assembly panel 110 may include a single or a plurality of solar panels which are operative to absorb photons in sunlight and create a photovoltaic effect that converts the sunlight into electricity. The components housed in the assembly housing 120 then utilize electricity to direct some air from in the vehicle over a cooling surface and then back into the vehicle and some air from in the vehicle over a warming surface and then back into the vehicle, as described below with reference to FIGS. 3-5.

[0016] Referring now to FIGS. 1, 2, 3, 4, and 5, the assembly housing 120 includes a plurality of temperature control components and a plurality of electrical control components. The temperature control components include a thermoelectric Peltier cooler 130, a cool side heat sink 131, a cool side distribution fan 132, a hot side heat sink 133, a hot side distribution fan 134, and a pair of intake fans 135. The electrical control components include a charge controller 140, a controller 141, and a battery 142. The exterior of the assembly housing 120 includes a front vent 121, a pair of side screens 122 each positioned on opposing sides of the assembly housing and disposed in a side wall of the assembly housing 120, and a manually actuated switch 123. While most of the side walls of the assembly housing 120 may be constructed of solid material, it is contemplated that the front vent 121 may include a plurality of fins to allow air to flow in and out of the front of the assembly housing 120 through the front vent 121 and side screens 122 may be formed of a mesh material to allow air to flow in and out of the sides of the assembly housing 120 through the side screens 122.

[0017] The interior of the assembly housing 120 may be divided by a divider wall 124 so as to form an upper compartment and a lower compartment. The fins of the front vent 121 which are in front of the upper compartment may be angled upward (i.e., directing away from the lower compartment) and the fins of the front vent which are in front of the lower compartment may be angled downward (i.e., directing away from the upper compartment). The divider wall 124 is positioned such that air flowing into the side screens 122 may enter the upper compartment or the lower compartment. Positioned next to each of the side screens 122 is one of the intake fans 135. When in provided with electricity, each intake fan 135 is operative to pull air from outside of the assembly housing 120 into the assembly housing 120 through the side screen 122 that it is positioned next to.

[0018] Integral with the divider wall 124 is the thermoelectric Peltier cooler 130, with the cool side thereof oriented to face the lower compartment of the assembly housing 120 and the opposing hot side thereof oriented to face the upper compartment of the assembly housing 120. It is appreciated that when the thermoelectric Peltier cooler 130 is supplied with direct current electricity, it brings heat from one side to the other. Accordingly, the “cool side” of the thermoelectric Peltier cooler 130, as referenced herein, refers to the side of the thermoelectric Peltier cooler 130 from which heat is brought and the “hot side” of the thermoelectric Peltier cooler 130, as referenced herein, refers to the side of the thermoelectric Peltier cooler 130 to which heat is brought.

[0019] The cool side heat sink 131 is attached to the cool side of the thermoelectric Peltier cooler 130 and extends downward into the lower compartment of the assembly housing 120. The cool side distribution fan 132 is positioned behind the cool side heat sink 131, so that when activated, it directs air across the cool side heat sink 131 and out of the lower part of the front vent 121. It is contemplated that when the cool side distribution fan 132 is activated, it is primarily the air flowing into the side screens 122 that enters the lower compartment that is being directed across the cool side heat sink 131 and out of the lower part of the front vent 121 by the cool side distribution fan 132.

[0020] The hot side heat sink 133 is attached to the hot side of the thermoelectric Peltier cooler 130 and extends upward into the upper compartment of the assembly housing 120. The hot side distribution fan 134 is positioned behind the hot side heat sink 133, so that when activated, it directs air across the hot side heat sink 133 and out of the upper part of the front vent 121. It is contemplated that when the hot side distribution fan 134 is activated, it is primarily the air flowing into the side screens 122 that enters the upper compartment that is being directed across the hot side heat sink 133 and out of the upper part of the front vent 121 by the hot side distribution fan 134.

[0021] The assembly panel 110 may be electrically connected to the assembly housing 120, and more particularly, to the charge controller 140 in the assembly housing 120. The charge controller 140 is electrically interconnected with the controller 141 and the battery 142 so that the charge controller 140 can manage the supply of electricity from the assembly panel 110 to the controller 141 and to the battery 142 and the storage of such electricity in the battery 142. In addition, the controller 141 is electrically connected to the thermoelectric Peltier cooler 130, cool side distribution fan 132, hot side distribution fan 134, intake fans 135, and switch 123 and includes software containing instructions which enables it to selectively supply electricity from either the charge controller 140 or battery 142 either automatically or in response to actuation of the switch 123. It is appreciated that the electrical connections between components may be through electrical wiring (not shown).

[0022] In operation, when the thermoelectric Peltier cooler 130, cool side distribution fan 132, hot side distribution fan 134, intake fans 135 are supplied electricity, the Peltier cooler 120 operates to absorb heat in the air that is being directed into the lower compartment of the assembly housing 120 by operation of the intake fans 135 and across the cool side heat sink 131 by operation of the cool side distribution fan 132. As a result, air that exits the lower part of the front vent 121 by operation of the cool side distribution fan 132 is cooled relative to most of the air in the passenger compartment. At the same time, air being directed into the upper compartment by operation of the intake fans 135 is directed across the hot side heat sink 133 by operation of the hot side distribution fan 134 where it absorbs heat therein (which was transferred from the cool side of the thermoelectric Peltier cooler 130 by way of the hot side of the thermoelectric Peltier cooler 130). This air is heated through its absorption of heat from the hot side heat sink 133 prior to exiting from the upper part of the front vent 121 by operation of the hot side distribution fan 134.

[0023] Because this cooled air will be more dense than the ambient air in the vehicle, it will remain in a lower part of the passenger compartment, near the passenger seating. Conversely, because the heated air will be less dense than the ambient air in the vehicle, it will run up the windshield and stay adjacent to the ceiling of the passenger compartment of the vehicle. As such, it is contemplated that the temperature modulation assembly 100 may additionally operate to prevent the formation or accumulation of frozen material on a windshield on a sunny but cold day.

[0024] The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
