Heat collection device with condensation reflector tracking sunlight

Abstract

The invention relates to a heat collection device with a condensation reflector tracking sunlight. The heat collection device with the condensation reflector tracking the sunlight comprises an outer pipe, an inner pipe and the condensation reflector, and is characterized in that the outer pipe is a glass pipe, hollow protecting casing pipes are arranged at the two ends of the inner pipe which is arranged coaxially, the inner pipe is suspended in the hollow protecting casing pipes, at least one end of the outer pipe is provided with a metal end cover which can deform in the axial direction, the condensation reflector is located inside the outer pipe and is supported on the hollow protecting casing pipes of the inner pipe through supports at the two ends of the condensation reflector, a bearing bush or a bearing is arranged between each support and the corresponding hollow protecting casing pipe, the reflective panel of the condensation reflector focuses on the central axis of the inner pipe, the back face of the condensation reflector is provided with a sensing magnet, the sensing magnet extends to the other end from one end along the back face of the condensation reflector in a spiral involute mode, and the outer wall of the center of the backlight area of the outer pipe is provided with a magnet moving slowly in the axial direction.

Description

technical field [0001] The invention relates to a heat collecting device, in particular to a heat collecting device containing a light concentrating reflective plate for tracking sunlight. Background technique [0002] Since the position of the sun changes throughout the day, in order to give full play to the heat collection effect of solar heat collectors, various forms of sun tracking devices have emerged. They generally change the direction of the entire solar collector to make the sun The irradiation can be with direct sunlight collector tube. This mechanism for changing the direction of the entire solar heat collector is generally more complicated, and the inlet and outlet waterways of the solar heat collector need to be modified. [0003] In order to improve the thermal efficiency of the solar heat collecting device, it is often necessary to install a concentrating reflector in the solar heat collecting device to improve the thermal efficiency of the heat collecti...
