The present invention provides a solar heat accumulation apparatus using a Fresnel lens and a heat pipe comprising: a concave reflector (110) to make a focus to an upper part by reflecting sunlight and a Fresnel lens (120) installed in the upper end of the concave reflector to make a focus to a lower part; a heat collecting device (140) installed between the concave reflector and the Fresnel lens (120), and located on the focus of the concave reflector and the Fresnel lens (120); a heat pipe (130) whose one side is inserted into the lateral side of the heat collecting device (140), and installed to be inclined more upwards while getting farther away from the heat collecting device; a heat sink plate (160) inserted into the other side of the heat pipe (130) to radiate heat; a heat exchanging part (150) having a sealed structure to transmit the heat generated from the heat sink plate to a heat transfer medium; a heat storage tank (180) to store the heat transfer medium heated from the heat exchanging part (150); and a circulating pipe (170) to circulate the heat transfer medium by connecting the heat exchanging part (150) with the heat storage tank. The present invention has effects of improving the light collecting efficiency by using a reflector and a Fresnel lens at the same time, improving the heat collecting efficiency by installing a heat collecting device in the focal position of a reflector and a Fresnel lens, and storing the solar heat collected thereby in a heat storage tank through a heat exchanging device by using a heat pipe. |
