Benefits of technology

[0004]A sun shield for shielding outdoor electrical equipment from sunlight is provided. The sun shield comprises a front, the front capable of shielding a front portion of the outdoor electrical equipment; a pair of sides, the pair of sides capable of shielding respective side portions of the outdoor electrical equipment; and a slanted roof, the slanted roof capable of shielding a top portion of the outdoor electrical equipment. Preferably, the slanted roof is provided at an angle such that sunlight is reflected no matter the elevation or azimuth of the sun during the day. The sun shield is capable of being fastened to a cover of the outdoor electrical equipment leaving an air gap between the sun shield and the cover of the outdoor equipment. Advantageously, the air gap provides for air flow between the sun shield and the cover of the electrical equipment, encouraging heat dissipation. The sun shield is capable of being fastened to the outdoor electrical equipment by attachment to pre-existing screw holes in the cover of the outdoor electrical equipment or bracketing to a wall mount.

Problems solved by technology

However, an inverter, particularly one installed in a desert climate, can suffer from the effects of excess heat.
When electrical equipment overheats, output decreases, and, if this occurs frequently, the overall lifespan of the equipment will be considerably shortened.
However, even though most inverters work well enough at cooler outdoor temperatures, overheating becomes an issue at higher outdoor temperatures.

Embodiment Construction

[0015]FIG. 1 illustrates an exemplary pair of sun shields 100 installed on outdoor electrical equipment, according to a preferred embodiment of the present invention. FIG. 2 shows a close-up perspective of the sun shields 100. As illustrated, each of the sun shields 100 is installed over a respective solar power inverter used to convert direct current (DC) generated by solar panels 210 to alternating current (AC) used in the home. It is to be understood that various different styles / designs for inverters exist, and that the present invention will be able to accommodate any of these. Further, it is to be appreciated that a sun shield 100 could be used in conjunction with various other types of outdoor electrical equipment. Thus, it is to be understood that the examples described herein are meant to be illustrative, not limiting. Various possible designs for the sun shield 100 exist; the exact dimensions, materials, and structure will depend on such factors as the size and type of the...

Description

FIELD OF THE INVENTION[0001]The present invention relates to thermal management of electrical devices and systems.BACKGROUND[0002]When solar energy equipment is installed, it is necessary to place outside the building an inverter to convert the direct current (DC) generated by the solar panels to alternate current (AC) used in the business or home. However, an inverter, particularly one installed in a desert climate, can suffer from the effects of excess heat. When electrical equipment overheats, output decreases, and, if this occurs frequently, the overall lifespan of the equipment will be considerably shortened.[0003]Typically, an inverter will have an internal cooling system that includes a heat sink and a fan. The heat sink works by transferring thermal energy from the inverter to the surrounding air which is of a lower temperature. To increase heat dissipation efficiency usually the heat sink will include several fins that increase surface area in contact with the air. To furth...
