All-glass evacuated tube solar collector

Abstract

The invention belongs to the technical field of water heaters, and provides an all-glass evacuated tube solar collector comprising a mounting rack, a heat collecting mechanism and a heat preservationwater tank; the mounting rack comprises a placement sleeve, a vertical branch pipe, a transverse branch pipe, a placement rack, a first placement plate and a second placement plate; the upper part ofthe first placement plate is provided with a first mounting barrel, and the upper part of the second placement plate is provided with a second mounting barrel; the first mounting barrel and the secondmounting barrel are arranged in an up-and-down staggered manner in sequence; the heat collecting mechanism comprises a first all-glass evacuated tube and a second all-glass evacuated tube; and the outer walls of the first all-glass evacuated tube and the second all-glass evacuated tube are each provided with a protecting mechanism comprising a protecting sleeve, a support sleeve, an outer sleeveand an operating board. The all-glass evacuated tube solar collector provided by the invention is simple in structure, convenient in installation and high in heat collecting efficiency, and benefits promotion and application, and the all-glass evacuated tubes are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an all-glass vacuum tube solar heat collector. Background technique [0002] The all-glass vacuum tube solar collector is commonly known as an elongated thermos. The outer wall of the inner tank has a solar absorbing coating, the inner tank is filled with water, and the inner and outer glass layers are of high vacuum, which plays the role of thermal insulation; After the water is stratified, the hot water floats up to produce a siphon, and the cold and hot water circulate naturally, and the cold water is gradually heated; [0003] The all-glass vacuum tube is composed of two concentric glass tubes, the inner and the outer. The selective absorption wax with high absorption rate and low emissivity is deposited on the outer surface of the inner tube to form a heat absorber. Its shape is like an elongated thermos bottle; [0004] But there are certain problems. The all-glass ...

AI Technical Summary

Problems solved by technology

[0004] But there are certain problems. The all-glass vacuum tube is fragile and not pressure-resistant. It is inconvenient to install and disassemble, and it is easy to damage and cause water leakage. It takes a long time. At the same time, the general all-glass vacuum tube is a single-layer structure, and the heat collection efficiency is relatively low.
