Efficient solar heat collector

Abstract

The invention provides an efficient solar heat collector, and belongs to the technical field of solar energy. The efficient solar heat collector comprises a machine base and a heat collecting shell, wherein an opening in the heat collecting shell is upwards arranged, a heat insulation layer is arranged on the inner wall of the heat collecting shell, and a heat collecting plate core is arranged on the heat insulation layer and is tightly connected with a plurality of tube banks which are arranged in parallel at equal intervals; an upper header and a lower header are connected with the upper ends and the lower ends of the tube banks in a communication mode respectively; a transparent cover plate is further arranged on the opening of the heat collecting shell, a supporting frame is arranged at the lower end of the heat collecting shell, and a rotating disc is connected to the lower end of the supporting frame and is rotationally connected to the machine base through a rotating shaft; and a driving motor for driving the rotating disc to rotate is arranged on the machine base, a connecting rod is further arranged on the machine base, a light source sensor is arranged at the end of the connecting rod, and an adjustable light gathering device is further arranged on the outer side of the heat collecting shell. According to the light intensity of the solar light, the orientation of the heat collector can be changed, more solar light can be collected, and therefore the heat collection effect can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy and relates to a high-efficiency solar heat collector. Background technique [0002] A solar collector is a device that absorbs solar radiation and transfers the generated heat energy to a heat transfer medium. In the heat utilization of solar energy, the key is to convert the sun's radiant energy into thermal energy. Since the solar energy is scattered, it must be concentrated. Therefore, the heat collector is a key part of various solar energy devices. [0003] Such as the Chinese invention application: (Application No.: 201110361165.8) discloses a flat solar collector, comprising: a rectangular bottom frame, a set of collector frames fixedly connected to both ends of the bottom frame, a bottom insulation layer, a side insulation layer, Serpentine tube sheet core fixing device, heat-absorbing coating plate and glass cover plate, said serpentine tube sheet core fixing device includes a plat...
