A heat conducting plate is fixedly sleeved on a boss of a heat insulation sealing plate, the bottom of a conical heat insulation sealing shell is in sealed connection with the upper end surface of the heat insulation sealing plate, a one-way bleed valve penetrates through the roof of the heat insulation sealing shell, an upper one-way valve is arranged at the upper part of the conical heat insulation sealing shell in a penetrating manner, a plurality of lower one-way valve are arranged at the bottom of the conical heat insulation sealing shell, the upper one-way valve is connected to a hydraulic generator through a junction pipe, the lower part of a conical heat collecting shell is arranged outside the conical heat insulation sealing shell with a gap left, the bottom of the conical heat collecting shell is connected with the upper end surface of the heat conducting plate in a sealed manner, the top of the conical heat collecting shell is provided with a hole over against the one-way bleed valve, the outer surface of the conical heat collecting shell is coated with a selective absorption coating material or is brushed into black, a conical light-transmittable shade is arranged on the outer surface of the conical heat collecting shell with a gap left, the one-way bleed valve penetrates through the top of the conical light-transmittable shade and is connected with the conical light-transmittable shade in a sealed manner, a to-be-heated fluid input pipe and a water drain valve are arranged in the solar electrothermal generator, and a reflector is arranged at a position which has a certain distance with the downsun side of the outer surface of the conical light-transmittable shade. The novel solar electrothermal generator has the advantages of simple structure and high cost performance.

Description

technical field [0001] The invention relates to solar energy utilization technology, in particular to a solar electric heating generator. Background technique [0002] Today, although the solar energy utilization technology has reached maturity, the solar energy utilization technology is not high enough, and the defects are obvious, mainly because the cost is high and the solar energy utilization efficiency is low, because the cost of the existing solar cells remains high, and the power generation efficiency is only about 10%. The cost of solar thermal power generation or heat utilization devices is not low, and the efficiency is not high. The basic structure of existing vacuum tube collector type solar water heaters is to connect the thermal insulation water tank at the heat conducting end of the parallel vacuum tube collectors. This kind of water heater is mainly costly because of the complex structure and process of the vacuum tube collectors. Existing solar installation...

The cost of solar thermal power generation or heat utilization devices is not low, and the efficiency is not high

The basic structure of the existing vacuum tube collector type solar water heater is to connect the thermal insulation water tank at the heat conducting end of the parallel vacuum tube collectors. This kind of water heater is mainly costly due to the complex structure and process of the vacuum tube collector

Existing solar installations hardly utilize solar light and thermal energy at the same time, the key is limited by cost and solar energy density
