Description

High-thermal-conductivity solar heat collector

Technical Field

The utility model relates to the technical field of heat collectors, in particular to a solar heat collector with high heat conductivity.

Background

Solar collectors refer to devices that absorb solar radiation and transfer the generated thermal energy to a heat transfer medium. In the heat utilization of solar energy, the key point is to convert the radiation energy of the sun into heat energy, and the solar energy is relatively dispersed and must be collected by some means, so the heat collector is a key part of various solar energy utilization devices. Due to different purposes, the heat collectors and the types of systems matched with the heat collectors are classified into a plurality of types and names, such as solar cookers for cooking, solar water heaters for producing hot water, solar dryers for drying articles, solar furnaces for melting metal, solar houses, solar thermal power stations, solar seawater desalinizers and the like.

The solar thermal collector who conventionally uses among the prior art generally includes the mount and is fixed in the evacuated collector tube on the mount, absorbs solar energy and turns into solar energy heat energy through evacuated collector tube during the use, generally all can leave certain clearance between two adjacent evacuated collector tubes when preparing to the sunlight that sees through the clearance when using directly shines subaerial, can't be utilized by evacuated collector tube, has caused certain waste, consequently can't satisfy people's requirement.
