Solar thermal collectors, solar thermal power collection panels and solar heating and hot water systems

Abstract

The invention relates to the technical field of solar energy, and particularly relates to a solar optothermal collector, an optothermal electricity collecting plate and a solar heating hot water system. The solar optothermal collector comprises a shell, wherein an upper shell body of the shell is provided with a convex lens light-gathering plate; copper heat collecting pillars are arranged below the convex lens light-gathering plate and in the shell, and a cavity in each copper heat collecting pillar is provided with nanometer metal heat conduction oil. The solar optothermal electricity collecting plate comprises the solar optothermal collector and a solar photoelectricity collector. The solar heating hot water system comprises the solar optothermal electricity collecting plate, a hot water device, a heating thermal storage device and an electricity storage device. The solar optothermal collector, the optothermal electricity collecting plate and the solar heating hot water system provided by the invention are capable of successfully collecting heat of a solar middle and high temperature region, and further, the nanometer metal heat conduction oil is used for promoting full utilization of collected heat and for heat conduction.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a solar photothermal collector, a photothermoelectric collection panel and a solar heating and hot water system. Background technique [0002] At present, the application of solar energy is relatively common, and various products have been widely used, among which domestic water heaters are the most widely used, and the light and heat collectors are generally: vacuum tube collectors, U-shaped tube collectors, flat plate collectors, etc. However, this kind of heat collector also has certain disadvantages. It can only absorb solar light and heat energy in the low temperature zone of 10-100°C, and can only be used for hot water bathing, and cannot absorb solar heat in the medium and high temperature zone of 100-100°C. 260°C thermal energy, so the solar energy cannot be fully obtained and widely used. Contents of the invention [0003] The object of the present invention is to provide ...
