Electric motor insulating sheet and a manufacturing method therefor

An insulation sheet for electric machine that forms slot insulation sheet is configured by an aramid paper and a PPS film directly pressure laminated without use of an adhesive. This means that no adhesive layer interposes the aramid paper and PPS film. PPS film is less costly as compared to a polyimide film and possesses better thermal properties such as higher heat emissivity and is highly resistant to heat. Thus, high strength is maintained even when subjected to high temperature over extensive time. Further, because the aramid paper and PPS film are laminated directly without an adhesive layer, the laminate is reduced in thickness. This allows further thinning of the laminate.

The present invention relates to a photovoltaic module characterized by comprising a heat radiating sheet overlaid with a ceramic coating layer, which is attached to a conventional photovoltaic module. In a method of increasing heat radiation with the aid of the ceramic coating layer provided on both sides or one side of the heat radiating sheet, heat generated by a solar cell due to the differences in thermal emissivity, thermal shear rate and surface area of a material is transferred to a solar EVA and then a heat radiating sheet thin plate that serves as a carrier, and returns back to the ceramic coating layer for emission. A high thermal emissivity is obtained by having a so-called heat transfer phenomenon in one direction, which resultantly improves a heat radiation performance and increases the refrigeration efficiency of the photovoltaic module and its peripheral devices to thus lower the internal temperature. As such, the power generation rate and efficiency through a module to which the heat radiating sheet is applied can be maximized, and a photovoltaic module with such a heat radiating sheet can maintain a change in the power generation rate traditionally due to a change in the surface temperature at a constant level, thereby increasing the annual power generation rate by 3-5% compared to that of the conventional one and improving the power generation effect during the summer season by 5-10%. Further, wide applicability can be ensured by equally applying the photovoltaic module of the present invention to areas having severe heat or high-temperature and high-humidity tropical weather as well as desert areas. In addition, the photovoltaic module according to the present invention is advantageous in that it is applicable not only to a new module but also to an already existing module, which makes it possible to manufacture those photovoltaic modules under the same process conditions as with the conventional ones without modifying the existing equipment.
