Embodiment Construction

[0015] figure 1 It is a principle diagram of the present invention. exist figure 1 , the operating principle of the device can be explained step by step as follows:

[0016] The invention is a device capable of introducing concentrated sunlight by using a light pipe or an optical fiber, and storing heat by using a high-temperature phase-change energy storage material, thereby realizing providing high-temperature heat energy for users. During the operation of the device, after the sunlight is gathered in a special way, the light energy density is increased and sent into the light guiding channel (1), which can be a light guide or a family of optical fibers. Passed through the light guide channel (1), enter the heat collecting cavity (11) in the outer casing (9) with a vacuum layer (8) from the light inlet (3) through the transparent light inlet window (2), and the heat collecting Light-to-heat conversion is realized in the cavity (11) to generate heat energy; the heat energy...

Abstract

The invention relates to a light conductive energy-gathering high-temperature phase variable accumulation solar-energy generator, which comprises: a light conductive channel, a transparent window, a outer frame, a heat collecting chamber, a heat accumulator, a heat conductive bar, a heat conductive plate, and thermal-insulated material. Wherein, the heat accumulator is inside the frame and above the heat collecting chamber; the heat conductive bar through the heat accumulator is connected to the lower part of heat conductive plate; the frame is formed by two frames whose interlayer space are vacuumed. The sunlight via the light conductive tube or optical fiber and transparent window enters the heat collecting chamber to be transformed into heat energy, which via the conductive bar is stored into heat accumulator. The invention can use high-temperature phase variable accumulation material to store the heat. When user needs heat, the energy is provided via the conductive plate.

Description

Technical field [0001] The invention belongs to the technical field of solar energy concentration and solar thermal utilization. Specifically, it is a device that can use light pipes or optical fibers to guide concentrated sunlight, and use high-temperature phase-change energy storage materials to store heat, so as to provide users with high-temperature heat energy. Background technique [0002] Among the currently popularized solar collectors, all-glass vacuum tube collectors and all-copper flat-plate collectors are the main ones. But these two types of solar collectors can provide thermal energy below 90°C, and generally can only provide domestic hot water for users. When the user needs higher temperature heat energy (>100°C), such as generating high-temperature steam, civil cooking, etc., this type of collector generally cannot meet the requirements. Although there is a solar cooker with direct reflection focusing that can be used for cooking functions, it requires t...
