Novel flat-plate solar collector

Abstract

The invention discloses a novel flat-plate solar collector which comprises a collector frame, a collector back plate, a heat insulation layer, a heat absorption plate, a working medium pipeline and a light permeable layer. The collector back plate, the heat insulation layer, the heat absorption plate, the working medium pipeline and the light permeable layer are sequentially arranged in the collector frame from bottom to top. The working medium pipeline is composed of flat pipes and flat connection pipes, wherein the flat pipes are arranged at intervals, and the two ends of each flat connection pipe are connected with the two corresponding adjacent flat pipes. Pressing strips are clamped to the outer edge above the collector frame. Adhesive sealing belts adhere to the joints between the pressing strips and the light permeable layer. Glass adhesive tape is arranged between the collector frame and the light permeable layer and arranged between the collector frame and the collector back plate. The whole working medium pipeline is of an S-shaped structure and composed of the flat pipes and the flat connection pipes, wherein the flat pipes are arranged at intervals, and the two ends of each flat connection pipe are connected with the two corresponding adjacent flat pipes. A layer of first electric heating cloth is arranged between the heat insulation layer and the heat absorption plate. The novel flat-plate solar collector is simple in structure, reasonable in design, good in sealing performance and high in heat collection efficiency.

Description

technical field [0001] The invention relates to the technical field of solar energy equipment, in particular to a novel flat solar heat collector. Background technique [0002] In the heat utilization of solar energy, the key is to convert the sun's radiant energy into heat energy. Because the solar energy is relatively scattered, it must be concentrated, so the heat collector is a key part of various solar energy devices. Heat collectors are generally divided into flat plate heat collectors, concentrating heat collectors and flat reflectors. [0003] Judging from the current state of world economic development, construction, transportation and industry have always been the three major energy-consuming industries, especially the construction industry. In developed countries, building energy consumption has accounted for 25-40% of the total energy consumption. In building energy consumption, heating, cooling, air conditioning and domestic hot water can account for 75%. The...
