Solar heat exchange system with high temperature heat conducting medium

Abstract

The present invention relates to one kind of heat exchange system, and is especially one solar heat exchange system with high temperature heat conducting medium. It has heat collector comprising several stages of solar heat absorbing vacuum tubes, heat exchanger and storage cylinder with high temperature heat conducting medium, connected via pipeline. One circulating pump is set in the inlet of the heat collector and can raise the temperature of the heat conducting oil to 200 deg.c. The heat conducting oil entering into the heat exchanger transmit heat to other object. The present invention may be produced in fast solar water boiler, solar energy air conditioner, solar energy rice cooker, solar energy stoving device, etc.

Description

technical field [0001] The invention relates to a heat exchange system, in particular to a heat exchange system using solar energy through a high-temperature heat-conducting medium. Background technique [0002] The current vacuum tube solar heat collection system is generally used to directly use solar energy to heat water. The medium flowing in the tube is water. Although the temperature inside the tube of the vacuum tube heat collector can reach above 200 °C in the air, the boiling point of water is only limited. 100°C, the heat energy that can be continuously provided is below 100°C. Due to the low heat collection temperature, it is very difficult to realize large-area, large-capacity solar heat collection, heat storage, and heat exchange. The amount of heat storage heat medium is large. The heat exchange area of ​​the heat exchanger is large. Contents of the invention [0003] The purpose of the present invention is to propose a solar high-temperature heat-conducting...
