Solar energy radiation absorbing device and comprehensive utilization system of same

Abstract

The invention discloses a solar energy radiation absorbing device. The solar energy radiation absorbing device comprises a solar panel, a heat absorbing plate and a first heat resisting device; the solar panel is arranged on the upper surface of the heat absorbing plate, and the heat absorbing plate is used for absorbing light energy which is not absorbed by the solar panel and heat generated by work of the solar panel; a first heat exchanging passage is arranged on the heat absorbing plate; the first heat resisting device is arranged at an inlet of the first heat exchanging passage; the firstheat resisting device comprises a heat insulation pipe and a connection pipe; and the heat insulation pipe is arranged in the connection pipe an can extend into the first heat exchanging passage along the connection pipe to prevent heat exchange between a heat exchanging medium which flows from the first heat resisting device to the heat absorbing plate and the heat absorbing plate. According tothe solar energy radiation absorbing device, by adjusting heat exchanging area of the heat absorbing plate and the heat exchanging medium, adjustable and controllable energy is obtained.

Description

Technical field [0001] The invention relates to the technical field of comprehensive utilization of solar photovoltaic light and heat, in particular to a solar radiation absorption device and a comprehensive utilization system of the device.

Problems solved by technology

Solar photovoltaic power generation has low energy conversion efficiency. Only solar energy within a certain spectral range can produce photoelectric effects when projected onto solar panels. A large part of energy is wasted. With the advancement of technology, photovoltaic Photothermal comprehensive utilization device, people convert light energy into electrical energy through solar cells, convert sunlight that is not absorbed by solar cells into heat energy through heat-absorbing plates, and then transfer the heat in the heat-absorbing plates to heat energy through heat-exchange media. user use

However, the heat utilization form of the existing photovoltaic photothermal comprehensive utilization device is simple, the heat exchange process between the heat exchange medium and the heat absorption plate cannot be adjusted, and the heat brought by the heat exchange medium to the user is greatly affected by the light and the environmental climate
