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 multi-directional tracking heat pipe 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 solar mirror support of different shapes; each solar optical mirror can rotate around the shaft, and meanwhile the solar mirror support can move, so that the multi-directional tracking that the solar mirror rotates around a starting shaft and moves together with the solar mirror support is realized; as the multi-directional tracking reduces the difficulty in homotaxial tracking, the range of the focused cylinder area is reduced, and the focusing multiple and the using temperature are increased; as solar heat pipe utilization equipment is arranged in a cylinder interval on ground or a building, when the solar mirror moves, the solar heat pipe utilization equipment can keep still, the focal length is variable zooming and tracking, and the solar heat pipe utilization equipment realizes the utilization of the focused and tracked solar energy in a cylinder; and the application of the solar energy, such as thermal power generation, heating, refrigeration, hot water, boiling water and the like, is realized by using the heat pipe as a solar energy converter and perfectly combining the heat pipe technology and the optical mirror technology. The invention provides an array structure of the system, which is suitable for systems of different scales, and simultaneously suitable for large-scale utilization of the solar energy, particularly the heat utilization of the solar energy.

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 mainly adopts three solar energy collection technologies of trough type, tower type and butterfly type to realize high temperature solar thermal power generation application . 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 temperature cannot be rea...
