Problems solved by technology

In the process of tracking solar energy, the heat transfer oil moves together in the pipe, and the bellows are used at the heat transfer oil pipe and the outflow end to realize the connection between the moving pipe and the non-moving pipe; because the bellows need high temperature resistance and high reliability, etc. Requirements, so it becomes a key component, and at the same time, this kind of connection cannot guarantee the insulation requirements, so the heat loss and cost of the system are high

Abstract

The invention discloses a solar linear zooming and unidirectional tracking vacuum tube utilization system. In the system, a group of solar optical mirrors consisting of a plurality of reflecting mirrors, a Fresnel mirror and a plane mirror are adopted; a revolving shaft of each mirror is arranged on a linear or non-linear device; each solar optical mirror can rotate around the shaft; and a glass-vacuum tube is used a photo-thermal conversion device, and the solar energy is focused on a vacuum tube by a line focusing solar mirror, so that focusing collection and utilization of the solar energy is realized. As the vacuum tube is arranged in a cylinder interval on ground or a building, when the solar mirror moves, the vacuum tube keeps still, and the focal length is variable zooming and tracking; and therefore, the application of the zoomed and tracked solar energy, such as thermal power generation, heating, refrigeration, hot water, boiling water and the like, is realized. The invention provides an array structure of the unitization system, which is suitable for systems of different scales, and simultaneously suitable for large-scale unitization of the solar energy, particularly the utilization of solar thermal power.

Description

technical field [0001] The invention relates to the utilization of solar energy, especially the linear tracking with the focus of solar energy focusing on a straight line and the tracking of an array to realize comprehensive applications such as thermal power generation, heating, cooling, hot water, and boiling water of solar energy. Background technique [0002] The thermal application of solar energy mainly adopts glass vacuum tube heat pipe technology to realize the application of hot water at a temperature of 60 degrees. The high temperature thermal utilization of solar energy can realize the application of high temperature solar thermal power generation as long as the three solar energy collection technologies of trough type, tower type and butterfly type are adopted. . The existing hot water application with a low temperature of 60 degrees is a small-scale household application. Since there is no tracking system, the temperature cannot be raised and the use of high tem...
