Abstract: According to one embodiment, a cooling plate for a solar panel for cooling a solar panel comprises: a planar body positioned on the rear surface of a solar panel; and a fluid guide part comprising a plurality of flow paths for guiding a fluid for cooling the solar panel, between inlets formed on one side of the planar body and outlets formed on the other side of the planar body, wherein the surface of the planar body that comes into direct contact with a back sheet of the solar panel may be flat.

Abstract: Disclosed is a fuel processor. The fuel processor includes: a steam reformer unit configured to be disposed at an upper portion in a casing; a heat exchanger unit configured to be disposed at a lower portion of the steam reformer unit; a high temperature shift reforming unit configured to be disposed at a lower portion of the heat exchanger unit; a low temperature shift reforming unit configured to be disposed while enclosing an outer portion of the high temperature shift reforming unit; and a heat exchange chamber configured to be disposed at a lower portion of the high temperature shift reforming unit and exchange heat between reformed gas and a heat exchange fluid supplied through a channel part formed to drain the reformed gas and combustion gas and supply the heat exchange fluid.

Abstract: A solar heat shielding coating solution is disclosed. The solar heat shielding coating solution comprises a sol-gel organic-inorganic composite binder solution and a nanosized metal oxide ink. The sol-gel organic-inorganic composite binder solution includes a sol-gel organic-inorganic composite resin, which is composed of a mixture of an acrylic polymer resin and a sol-gel silicate as an inorganic ceramic, and a solvent. The nanosized metal oxide ink includes a nanosized metal oxide, a dispersant capable of effectively dispersing the nanosized metal oxide, and a solvent. The coating solution can be coated to a small thickness on glass while maintaining transparency. In addition, the coating solution has high visible light transmittance, infrared light blocking rate and hardness, and exhibits good weather resistance, solvent resistance and adhesiveness.
