A heat collecting tube for dish solar reflector to gather heat

Abstract

A heat collecting tube used for heat collection of a dish solar reflector, comprising a fluid pipe, a heat pipe, and a condensing head, characterized in that the underside of the fluid pipe near the middle section is provided with the condensing head, and the The heat pipe includes a heat absorption section (or an evaporation section) and a heat dissipation section (or a condensation section). With the light-condensing head as a boundary point, the left and right sides are respectively provided with the heat pipes, and the heat absorption sections of two adjacent heat pipes They are all wrapped in the condensing head, and the heat dissipation section is in the fluid pipe or integrated with the fluid pipe. In practical applications, the condensing head is always in the reflective At the focusing point of the mirror, the heat gathered by the focusing head is quickly transferred to the heat transfer working medium in the fluid pipeline through the heat dissipation section of the heat pipe, so as to achieve the purpose of high temperature heat collection.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization, and in particular relates to a technology of a heat collecting tube used for heat collection by a dish-type solar reflector. Background technique [0002] On the one hand, the level of human energy consumption continues to increase, on the other hand, conventional fossil energy is increasingly exhausted, and the pollutant emissions associated with conventional fossil energy are increasingly unable to meet people's demand for future energy. Solar energy, as an inexhaustible new clean energy, is getting more and more attention, and the development of solar energy is making progress day by day. Among them, solar power generation is an advanced development and application of solar energy. It converts solar energy into electrical energy through certain means to meet the electricity demand of modern society. [0003] Currently popular solar power generation is mainly divided into two fo...
