Embodiment Construction
[0015] The present invention proposes a fin electric heating device for simulating the high heat flux density of focused solar energy, which will be further described below in conjunction with the accompanying drawings.
[0016] figure 1 Described is a fin electric heating device simulating the high heat flux density of focused solar energy. The electric heating device is composed of several external fins 1, an electrical insulating layer 2, an electric heating coating 3, a heat-absorbing wall surface 4, and a filled heat insulating layer 5. It is composed of current wire 6 and DC power supply 7. Unlike traditional fins that enhance heat dissipation by expanding the surface area, the external fins 1 in the present invention enhance the heat flow of the heat-absorbing wall 4 . The electric heating coating 3 is evenly or unevenly plated on the surface of the external fin 1 and the heat-absorbing wall 4 according to specific conditions. Under the condition that current lead 6 i...

A fin electric heating device for simulating high heat flux density of focusing solar energy consists of multiple external fins (1), electric insulating layers (2), electric heating coating films (3),a heat absorbing wall surface (4), filling heat insulation layers (5), current leads (6) and DC power supplies (7). The external fins (1) have a function of enhancing heat flux of the heat absorbingwall surface (4). When the current leads (6) is powered on, the electric heating coating films (3) adjusts the heat flux density in 0-200 W / cm<2> and a larger range and heats the external fins (1) andthe heat absorbing wall surface (4). The heating power of each external fin (1) and the heat absorbing wall surface (4) can be independently adjusted by the DC power supplies (7). The filling heat insulation layers (5) among the external fins (1) can ensure that heat is completely absorbed by the heat absorbing wall surface (4). The section of each external fin (1) from the height to the wall absorbing wall surface (4) is a uniform section or a variable section, and heat produced by the external fins (1) can be absorbed by the wall absorbing wall surface (4).
Description
technical field [0001] The invention is used in the field of electric heating, and in particular relates to an electric heating pipeline with external fins used in laboratory electric heating experiments. Background technique [0002] As a natural resource, solar radiant energy has shown its unique advantages due to its abundant reserves and non-pollution, and has been recognized by the international community as one of the most promising energy sources in the future. Domestic and foreign investment in research on solar energy utilization technology is increasing. The biggest difficulty in carrying out solar energy-related experimental research under laboratory conditions is to restore the real solar radiation heating conditions. It is necessary to develop a heating method with high temperature, stability, low cost and adjustable heating power. [0003] At present, the heating heat sources used in the experimental research of solar energy utilization technology can be roug...
