Novel vacuum-tube type solar collector

Abstract

The invention discloses a novel vacuum-tube type solar collector in the field of the solar collectors. The novel vacuum-tube type solar collector comprises a cold-water tank and a hot-water tank through a plurality of vacuum collector tubes. The cold-water tank and the hot-water tank are mounted on a bracket. The hot-water tank is disposed at the top end of each vacuum collector tube, and a hot-water outlet is formed on the top portion of the hot-water tank. The cold-water tank is disposed at the bottom end of each vacuum collector tube, and a cold-water inlet is disposed on the cold-water tank. An opening is formed at each of two ends of each vacuum collector tube, the upper end of each vacuum collector tube is inserted into a hot-water tank device, and the lower end of each vacuum collector tube is inserted into a cold-water tank device. Provided with the cold-water tank and the hot-water tank at the same time, the novel vacuum-tube type solar collector is simple in structure. The whole heat-collecting process is good in flowing characteristic, the hot-water outlet is high in temperature and easy to regulate, and therefore novel vacuum-tube type solar collector is applicable to occasions with water continuously flowing in and out.

Description

technical field [0001] The invention relates to a solar heat collector, in particular to a vacuum tube type solar heat collector. Background technique [0002] The existing vacuum tube solar collector is mainly composed of a vacuum heat collecting tube and a water tank on the top, wherein the vacuum heat collecting tube is composed of two coaxial round glass tubes, one end is open and the other end is closed, and the open end is inserted into the bottom of the water tank above it. , The bottom of the water tank is provided with a water inlet and a water outlet. This kind of heat collector is usually used in intermittent operation occasions. After the cold water enters the water tank during work, the water in the water tank is heated to a certain temperature by natural convection and then discharged; when this kind of heat collector is used for continuous water inlet and outlet , because the water tank has both water inlet and water outlet, and the open end of the vacuum tub...

Problems solved by technology

This kind of heat collector is usually used in intermittent operation occasions. After the cold water enters the water tank during work, the water in the water tank is heated to a certain temperature by natural convection and then discharged; when this kind of heat collector is used for continuous water inlet and outlet , because the water tank has both water inlet and water outlet, and the open end of the vacuum tube is both an inlet and an outlet, so the flow process of the working medium is complicated and unstable. Hot water with a higher temperature is not conducive to adjusting the temperature of the hot water
