Antifreeze and defrost type solar plate collector

Abstract

The invention discloses an anti-freezing and defrosting type solar panel heat collector, and aims to provide an anti-freezing and defrosting type solar panel heat collector capable of effectively anti-freezing and rapid defrosting. It includes a bottom plate, a heating plate, a refrigerant pipe, an outer frame and a single-chip microcomputer. A cavity is formed between the plates, the side of the outer frame and placed at the position of the cavity is provided with a ventilation mechanism for adjusting the air intake in the cavity, the outer frame is equipped with a temperature sensing element, and the back of the heating plate is equipped with an electric heating element. Both the temperature sensing element and the electric heating element are connected to the single-chip microcomputer. The beneficial effects of the present invention are: good antifreeze and heat preservation effects, rapid defrosting effect, improved defrosting efficiency, and the ability to change the air flow between the heating plate and the outer frame according to different environmental requirements, thereby changing The utilization rate of air energy ensures the antifreeze and heat preservation effect of the refrigerant pipe.

Description

technical field [0001] The invention relates to a solar heat collector, in particular to an antifreezing and defrosting type solar flat plate heat collector. 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. Higher efficiency collectors consist of collecting and absorbing devices. Heat collectors can generally be divided into several types such as flat plate heat collectors, concentrating heat collectors, and flat reflectors. Flat plate collectors are generally used for solar water heaters and the like. For cold areas where the temperature is below 0°C, when the existing solar panel collectors work in the external environment, it is easy to frost or freeze on the outer surface of the solar panel collectors, which leads to The efficiency of the c...

AI Technical Summary

Problems solved by technology

This utility model solves the problem that the energy consumption increases greatly when the refrigerant flows through the L-shaped connection node. When working, it is easy to frost or freeze on the outer surface of the solar panel collector, which leads to a decrease in the efficiency of the solar panel collector
