Low-thermal-loss wall-mounted type solar heat collector

Abstract

The invention discloses a low-thermal-loss wall-mounted type solar heat collector. The low-thermal-loss wall-mounted type solar heat collector comprises a galvanized steel sheet. An aluminum alloy outer shell is installed on one side of the galvanized steel sheet. A heat insulation plate is attached to the inner surface of the aluminum alloy outer shell. A heat plate core and a heat collecting pipe are installed in the aluminum alloy outer shell, and an air cavity is arranged between the heat plate core and the heat collecting pipe. The heat collecting pipe is provided with a medium inlet and a medium outlet, and an electromagnetic valve and a temperature gauge are arranged in the medium inlet and the medium outlet. According to the low-thermal-loss wall-mounted type solar heat collector, the integrated corrugated vacuum heat collecting pipe is preferably selected, the problems that when an existing U-type pipe is installed and welded, welding spots are missed, and the heat collecting effect is poor are solved, the service life of the equipment is prolonged, and the heat collecting effect is increased. Meanwhile, a PLC intelligent control system is adopted, the heat output power of the heat collector is accurately controlled, the energy collected through the solar heat collector is used reasonably and thoroughly, and the utilization efficiency of the energy is played to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of heat collectors, in particular to a wall-mounted solar heat collector with low heat loss. Background technique [0002] In the heat utilization of solar energy, the key is to convert the sun's radiant energy into heat energy. Because the solar energy is relatively scattered, it must be concentrated, so the heat collector is a key part of various solar energy devices. The definition of a solar collector is: a device that absorbs solar radiation and transfers the generated heat energy to a heat transfer medium. This short definition contains rich meanings: first: a solar collector is a device; second: a solar collector can absorb solar radiation; third: a solar collector can generate heat; fourth : Solar collectors can transfer thermal energy to heat transfer medium. Most of the existing solar heat collectors use U-shaped vacuum heat collecting tubes, and solder joints are often missed during installatio...
