Embodiment Construction

[0022] combine Figure 1-2 As shown, a solar glass vacuum heat collector tube 3 pressure series heat collector, including a heat absorbing component 1, the heat absorbing is mainly used as the main place where solar light energy is converted into heat energy, and is the core component of the present invention. combine figure 1 with 2 As shown in , the heat absorbing assembly 1 includes a medium pipe 2 and a plurality of glass vacuum heat collecting tubes 3, such as figure 2 As shown in , the number of glass vacuum heat collecting tubes 3 is only shown as three, in fact, more tubes can be set according to the heating requirements of the medium.

[0023] The traditional parallel structure adopts one main pipe and multiple branch pipes. The branch pipes communicate with the main pipe and are bent in the glass vacuum heat collecting tube 3. However, due to the large number of heat exchange nodes in this way, it is difficult to guarantee the temperature and stability of the outl...

Abstract

The invention relates to the technical field of solar energy application. The invention aims to provide a solar glass evacuated collector tube pressure-bearing series heat collector which comprises aheat absorption assembly, wherein the heat absorption assembly comprises a medium pipeline and a plurality of glass evacuated collector tubes, and the medium pipeline is sequentially bent into the glass evacuated collector tubes in an inverted-U shape to form series connection; one end of the medium pipeline communicates with the tail end of a medium inlet pipe, and the other end communicates withthe head end of a medium conveying pipe; the head end of the medium inlet pipe communicates with a medium source under pressure, and the tail end of the medium conveying pipe communicates with a heatpreservation box. A traditional parallel connection mode is changed, the series connection mode is adopted to form the heat absorption assembly, and media are in a heat superposition state all the time in the medium pipeline, so that heat exchange nodes are reduced, the temperature of the media is increased and stabilized, and the heat efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of solar energy applications, in particular to a solar glass vacuum heat collection tube pressure-bearing series heat collector. Background technique [0002] In recent years, with the progress and development of energy science, solar energy, as a clean, renewable and environmentally friendly energy, has attracted more and more attention from people, and has begun to be widely used in various industries. The current mainstream methods of solar energy application are mainly divided into solar photovoltaic application and solar thermal application. Solar thermal application is to use solar energy to heat the medium, so as to realize the collection and utilization of heat. The solar glass vacuum heat collector is a device that uses solar heat radiation to heat its internal medium and uses the medium to store heat. It has the characteristics of good economy, simple structure, and good universality. However, the...
