Solar heat collector with high light collection and heat conduction functions

Abstract

The invention discloses a solar heat collector with high light-collecting and heat-conducting functions, and belongs to the technical field of solar heat collection. A pair of light reflecting pieces is installed at the bottom end of a main heat-collecting pipe, sunlight is reflected to the backlight surface of the main heat-collecting pipe, the light-collecting and heating surface of the main heat-collecting pipe is expanded, in addition, a plurality of auxiliary heat collecting pipes are arranged on the main heat-collecting pipe in a distributing mode, the upper end walls and the lower end walls of the auxiliary heat collecting pipes are both wrapped around magnetic columns through elastic magnetism isolating layers, the magnetic columns are connected to a heat conducting plate through memory alloy rods, and after the temperature of the light receiving faces of the auxiliary heat collecting pipes rises, the memory alloy rods recover to the high-temperature spring phase state and contract to enable the magnetic columns to extrude the elastic magnetism isolating layers, and after the elastic magnetism isolating layers deform, the magnetism isolating effect on the magnetic columns is weakened, so that magnetic attraction strips located on the lower portions have the magnetic attraction effect on the displaced magnetic columns, the auxiliary heat collecting pipes are promoted to rotate to change the light receiving faces of the auxiliary heat collecting pipes, and the circulation is conducted, so that the auxiliary heat collecting pipes are comprehensively and uniformly heated, and heat transfer media are effectively and comprehensively conducted.

Description

technical field [0001] The invention relates to the technical field of solar heat collection, in particular to a solar heat collector with high light collection and heat conduction. Background technique [0002] A solar collector is a device that converts the sun's radiant energy into heat energy. Since the solar energy is relatively scattered, it must be concentrated, and the heat collector is a key part of various solar energy devices. [0003] Existing heat collectors used for solar water heaters generally use films of various lighting materials to lay on heat collecting tubes to efficiently collect direct sunlight. However, the heat collecting tube can only absorb light energy on the side facing the sun, while the backlight side is difficult to absorb light energy. The temperature of the backlight surface of the heat collecting tube is low, so it is difficult to achieve uniform heating, so that the heat transfer medium stored in the heat collecting tube is difficult to ...

Problems solved by technology

However, the heat collecting tube can only absorb light energy on the side facing the sun, while the backlight side is difficult to absorb light energy. The temperature of the backlight surface of the heat collecting tube is low, so it is difficult to achieve uniform heating, so that the heat transfer medium stored in the heat collecting tube is difficult to fully absorb. Heat conduction, resulting in insufficient solar heat collection efficiency and poor heat conduction effect
