Solar radiation absorbing device and its comprehensive utilization system

Abstract

The invention discloses a solar radiation absorbing device, which comprises: a solar battery panel, a heat absorbing plate and a first heat resistance device, the solar battery panel is arranged on the upper surface of the heat absorbing The light energy absorbed by the solar cell panel and the heat energy generated when the solar cell panel is working, a first heat exchange channel is opened on the heat absorbing plate, and the first heat resistance device is installed at the entrance of the first heat exchange channel; the first The heat-resisting device includes a heat-insulating pipe and a connecting pipe. The heat-insulating pipe is installed inside the connecting pipe and can extend into the first heat exchange channel along the connecting pipe to prevent the flow of the heat-exchanging medium from the first heat-resisting device to the heat-absorbing plate and The heat-absorbing plate performs heat exchange. The invention obtains an adjustable and controllable energy source by adjusting the heat exchange area between the heat absorbing plate and the heat exchange medium.

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 absorbing device and a comprehensive utilization system of the device.
