Problems solved by technology

Although the all-glass vacuum heat collecting tube has many advantages, it is easy to freeze in winter because of the water inside the tube; in addition, because the all-glass vacuum heat collecting tube is not under pressure, there is a risk of water leakage, which does not match the pressure of the water supply network in high-rise buildings

Abstract

A vacuum heat collector of solar energy uses the oscillating flow tube as the heat collecting tube. It includes: the out oscillating flow tube, the inner oscillating flow tube, the thermal insulating block cover and the glass vacuum tube. The oscillating heat flow tube is distributed for 2-3 layers on the circle of the glass vacuum tube which is made up of the inner glass tube, the out glass tube, the spring shelf and the getter; one end of the glass vacuum tube is open and one end of the inner and out tube mouth is fused, the other end is the half ball head. The inner glass tube is supported by the spring shelf which is set with the getter to absorb the gas when the glass vacuum tube works to keep the vacuum. The open end of the glass vacuum tube is set with the thermal insulating block cover to decrease the heat loss. So the invention has the big heat absorbing area and high heat collecting efficiency.

Description

technical field [0001] The invention belongs to the field of solar heat collectors, and in particular provides a solar vacuum glass heat collecting pipe using an oscillating flow heat pipe as a heat-absorbing inner pipe. The invention relates to an oscillating flow heat pipe (also known as a pulsating heat pipe), and is a solar heat collecting element with high freezing resistance, strong pressure bearing capacity and high heat collecting performance. Background technique [0002] Solar collectors are the key components of various solar energy utilization systems, and are mainly divided into two types: flat plate collectors and vacuum tube collectors. At present, the all-glass vacuum tube solar collector is the most widely used vacuum tube solar collector in China. The all-glass vacuum tube collector is the basic unit of the all-glass vacuum tube solar collector, and an all-glass vacuum tube collector is usually composed of several all-glass vacuum tube collectors. Althoug...
