Abstract

A sunshade generates usable electrical power by a combination of photovoltaic solar panels 230 and thermo�electric generation means 240. Photovoltaic (PV) solar panels 230 are located at the top of thermoelectric module over the surface of a parasol canopy. A thermoelectric generating means is also provided, comprising a Fresnel lens collector 220. A fan 270 is driven by power generated from the thermoelectric module. The fan sucks air in through windows 250 and over a domed interior towards constricted gaps 260. Low pressure is generated as the air exits the gaps 260 and additional air is entrained into the flow by the Coanda effect, resulting in a cooling airflow underneath the umbrella. The solar panels 230 are also cooled by the air flowing in to the fan 270 via windows 250. This cooling effect is beneficial for the efficiency of the solar powered panels.

Description

Description of Related Art

In many developing countries where domestic power supplies are either erratic or not widely available [e.g. many African and South American countries] emerging mobile telephone markets have been hindered by problems encountered when trying to charge/power the mobile devices.

The spread of mobile technology through these regions has benefitted individuals and businesses alike, but in order to encourage the growth of the mobile market, easy access to charging means must be made available.

In light of the lack of easily accessible domestic power supply, entrepreneurs (often sponsored by mobile network corporations] have set up market/street stalls providing charging facilities for customers whilst they wait, or carry out other tasks in town before collecting their charged devices afterwards.

There is a need for an improved method and means of providing clean, reliable and cheap energy for charging of mobile devices. Additionally, extracting usable energy from solar photovoltaic system is hindered by inefficient energy conversion. Overheating of PV modules cause the voltage to drop and power loss) thus, reducing the extent of overheating of the PY panels will lead to increased operational efficiency and a longer lifespan. An effective way of improving efficiency and reducing the rate of thermal degradation of a photovoltaic (PV) module is by reducing the operating temperature of its surface. This can be achieved by cooling the module and reducing the heat stored inside the PV cells during operation.

Summary of Invention

The primary objective of the present invention is to provide usable and self sufficient electrical generation device and a cooling system for comfort in combination with a parasol.

The system includes; a solar collector which forms the top part of a module system. The rest of the module which is integrated into top section of the parasol is made up of a pico photovoltaic system attached to the outside of module casing and thermoelectric hybrid system connected to a heat conductive layer and a heat sink and a thermoelectric powered fan which are housed inside the module casing. The fan is located in the bottom part of the module with a domed interior and bottomed out with small slits running around its edges for air outlet for the fan. The parasol pole attaches to the bottom of the domed area of the casing.

The photovoltaic panels are attached perpendicularly to the outside of the casing above the air inlet windows in the housing.

The parasol rib and canopy is attached to the outside of the casing, in this regard, the casing also functions as a top notch.

Brief descriptions of the drawings

The invention as well as a FIG.1 is a front view of the invention with the canopy in the open position FIG.2 is a top view of the invention in an open position FIG.3 is a front and inside view of the invention with the canopy in an open position FIG.4 is a front and inside view of the invention in greater detail, with a blowout section detailing the configuration of the internal components.

Detailed Description of the Preferred Embodiment

Examining FIG 1, The detailed picture is a photovoltaic-thermoelectric module incorporated into the top part of the parasol. the diagram shows the solar collector 200, preferably a fresnel lens collector, the rib and canopy 120 as well as the stem pole 110 and the electrical outlet 300.

FIG 2,is an illustration of the open parasol, clearly detailing two photovoltaic panels 230, and a fresnel lens solar thermal collector 220. The photovoltaic panels are attached to the sides of the casing just above the parasol canopy.

FIG.3, A clearer view of the invention, with the parasol in an open configuration, detailing at least two panels 230, the fresnel lens collector 220 and the ducted fan 270 attached to the thermoelectric and heat sink casing 240. the heat sink is partially visible through the window on the side of the casing 250 and the concentric air outlet vents 260 attached to the parasol stem 110 FIG.4, Is an exploded view of the invention. According to the drawing, attached to the outer shell of the casing 240, are hinges 235 which support the solar panels 230. The rib over which the canopy goes on 120 is also attached to the outer shell of the casing by brackets 245.

Inside the casing, a metal heat spreader 221 lies underneath the fresnel lens collector and is thermally glued to the hot side' of at least one thermoelectric module 225. A heat sink 250 is also attached with thermal glue to the thermoelectric module on its cold side. The windows in the casing are located directly below the panels. When operational, the thermoelectric powered fan 270 sucks in air via the windows, which passes through the heat sink and into the ducted section, where the dome shaped interior 265 forces the air to flow through the constricted gaps 260. The air velocity increases as a result of this and the low pressure caused by the high velocity of the exiting air. The Venturi effect as this phenomenon is known causes the leads air exiting to be entrained utilising the Coandä effect. The resulting airflow conditions the air under the parasol shade to provide comfort during hot and humid periods.

A low pressure area is created around the panels by the air being sucked into the heat sink through the window leading to an increased airflow around the panels which cools the surface of the panels thereby increasing the operational efficiency of the panels.

The electrical energy created from the panels is connected to a Universal Serial Bus outlet 300 located on the bottom third of the parasol pole by wires which run from the panels and alongside the body of the parasol pole 110.

This embodiment is advantageous over the prior art in that it not only utilises and combines currently known existing technology by utilising solar cells and thermoelectricity which when coupled with the appropriate battery system can be harnessed off-grid and on demand, but it also combines these technologies in a synergistic manner especially with respect to how thermoelectric generation is applied in powering a heat activated fan which cools the solar cells as well as its climate control and personal comfort applications.
