Example Embodiment

[0015] figure 1 It is a schematic 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 into a light funnel and storing heat through a high-temperature phase-change energy storage material, thereby realizing providing high-temperature thermal energy for users. During the operation of the device, sunlight is incident on the inner surface of the primary CPC (compound parabolic concentrator) (1), if the angle between the sunlight and the rotation axis of the primary CPC (1) is less than the When the lighting half-angle is used, the sunlight is reflected on the Fresnel lens (2), and after being transmitted by the Fresnel lens (2), most of the sunlight is converted into nearly parallel light, and is transmitted in the light pipe (3) transfer. The outlet of the light pipe (3) is connected to the inlet of the secondary CPC (4...

Abstract

The invention discloses a optical-hopper light conductive energy-accumulated high-temperature phase-variable forced recycle solar-energy furnace, which comprises a optical hopper, a energy accumulator, a recycle pump, a oil tank, and a user heat supplier. Wherein, the heat accumulator and the heat exchanger at inside the frame of energy accumulator; the tubes of heat exchanger is through the heat collecting chamber to connect the recycle pump and the oil tank; the oil tank via the heat conducive oil recycle tube is connected to the user heat supplier; the light is collected by the optical hopper, and via the transparent inlet window to enter into the heat collecting chamber to be transformed into heat energy and via the heat conductive plate to be transmitted to the heat accumulator to be stored; when user uses energy, switching on the recycle pump to pump the heat conductive oil of oil tank into the heat exchanger of energy accumulator to exchange heat with the heat accumulator to attain high-temperature heat conductive oil to be transmitted via the recycle tube to the user heat supplier. The invention can utilize the optical hopper to collector light, use the high-temperature phase variable material to store energy, and supply high-temperature heat to the user.

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 a light funnel to collect light and a light guide to guide sunlight into an energy storage device, use a high-temperature phase-change energy storage material to store energy, and provide users with high-temperature heat energy under the drive of a circulating pump. Background technique [0002] Among the currently popularized solar collectors, all-glass vacuum tube collectors and all-copper flat-plate collectors are the main ones. However, these two types of solar collectors can provide users with heat 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 wit...
