Abstract: A cooling apparatus is disclosed. The cooling apparatus includes a carrier and a flat-plate type cooling conduit. The flat-plate type cooling conduit is made of a high thermal conductive material and disposed on or in the carrier. The flat-plate type cooling conduit includes a conduit portion and a flat plate portion. The conduit portion has a conducting hole for conducting a coolant, and the flat plate portion is adhered to the carrier for allowing the coolant to perform heat exchange through a large contact area between the flat plate portion and the carrier. In addition, a cooling source gel can be used to perform heat exchange with the coolant in the conducting hole in order to improve the heat exchange efficiency of the cooling apparatus, and to effectively reduce the temperature of the carrier.

Abstract: Fibers of square cross sections are presented in the invention. The square fiber leads to higher packing density and results in higher wind resistance in fabrics as compared to the conventional round fibers and other polygonal fibers. Therefore, the square fiber is more suitable for manufacture of the windproof clothing. In addition, the square fibers exhibit higher luster than the round fibers and other polygonal fibers due to the flat and shiny fiber surface.
