Abstract

FIELD: power engineering; heat-transfer systems, external-combustion engine; power-generating facilities. SUBSTANCE: heat exchanger has chamber accommodating working-medium tube rigidly and coaxially fixed therein, and in addition, it is provided with absorbing lenses with mechanism rotating them about chamber; lenses are placed outside the chamber along tube over its entire length and at focal distance from it. Rotating mechanism has sun position tracking system which also functions to follow center of each lens and its focus on conventional straight line perpendicular to tangential line at focal point on tube surface; chamber is mounted for rotation through elevation angle to ensure perpendicular position of mentioned conventional straight line relative to generating line of tube cylindrical surface depending on sun position on dome of the sky throughout the year. Cylindrical wall of chamber is made of transparent material, such as glass, and filled with inert gas. Tube is made of high-melting metal and its heat-transfer surface is enlarged by inserting high-melting metal rod of screw thread as deep as almost to its center line. Covers and pipe connections are made of heat-insulating material capable of sustaining temperature as high as 2000 C. Working medium heating temperature in heat exchanger depends on heating temperature of tube surface, its flow speed through tube, length of tube, quantity and surface area of convex lenses. EFFECT: improved pollution control of environment due to use of solar energy for heating working medium.

Предлагаемое изобретение относится к области энергетики и может быть использовано в различных теплообменных системах, в двигателях внешнего сгорания, а также для выработки электроэнергии. Задачей предложенного изобретения является улучшение экологии окружающей среды за счет использования солнечной энергии для нагрева рабочей среды в теплообменнике. Выполнение задачи достигается тем, что в теплообменнике, имеющем камеру, внутри которой жестко и соосно с ней закреплена трубка для прохождения в ней рабочей среды, установлены вне камеры вдоль трубки по всей ее длине на фокусном расстоянии от ее поверхности собирающие линзы с механизмом вращения их вокруг камеры. Механизм вращения снабжен системой слежения за постоянным расположением Солнца, а также центром каждой линзы и ее фокусом на условной прямой, перпендикулярной к касательной в точке расположения фокуса на поверхности трубки, причем камера установлена с возможностью вращения ее по углу места для обеспечения перпендикулярности упомянутой условной прямой к образующей цилиндрической поверхности трубки в зависимости от места расположения Солнца на небосводе в течение года. Цилиндрическая стенка камеры выполнена из прозрачного материала, например стекла, и внутри камера заполнена инертным газом. Трубка выполнена из тугоплавкого металла, причем для увеличения поверхности съема тепла рабочей средой внутри трубки с контактированием по всей длине ее поверхности установлен стержень из тугоплавкого металла с винтовой нарезкой, достигающей по глубине почти оси стержня. Крышки и патрубки выполнены из теплоизоляционного материала, выдерживающего температуру до 2000°С. Величина температуры нагрева рабочей среды в предлагаемом теплообменнике зависит от температуры нагрева поверхности трубки, скорости прохождения ее через трубку, длины трубки, количества и площади выпуклой поверхности линз.The present invention relates to the field of energy and can be used in various heat transfer systems, in external combustion engines, as well as for generating electricity. The objective of the invention is to improve the ecology of the environment through the use of solar energy to heat the working environment in the heat exchanger. The task is achieved by the fact that in the heat exchanger having a chamber inside of which a tube is rigidly and coaxially attached to it for passing the working medium inside it, outside the chamber along the tube along its entire length at a focal length from its surface, collecting lenses with a mechanism for rotating them around cameras. The rotation mechanism is equipped with a tracking system for the constant location of the Sun, as well as the center of each lens and its focus on a conditional line perpendicular to the tangent at the focal point on the surface of the tube, and the camera is mounted to rotate it in elevation to ensure the perpendicularity of the said conditional line to forming the cylindrical surface of the tube, depending on the location of the Sun in the sky for a year. The cylindrical wall of the chamber is made of a transparent material, such as glass, and inside the chamber is filled with an inert gas. The tube is made of refractory metal, and to increase the heat removal surface by the working medium inside the tube with contacting along the entire length of its surface, a rod of refractory metal with a screw thread is installed, reaching almost the core axis in depth. Caps and nozzles are made of heat-insulating material that can withstand temperatures up to 2000 ° C. The temperature of the heating medium in the proposed heat exchanger depends on the temperature of the heating surface of the tube, the speed of its passage through the tube, the length of the tube, the number and area of the convex surface of the lenses.
