A method and device for testing the concentrating performance of a solar dish concentrator

Abstract

The invention discloses a method for testing condensation performance of a solar disc type condenser. The optical concentrating ratio distribution is determined by utilizing a method for measuring heat-flow density distribution on a spotlighting focal plane of the disc type condenser and local solar normal direct irradiance for many times in a timesharing manner. A testing device by adopting the testing method disclosed by the invention is composed of a rotary substrate (1), a heat-flow sensor (2), a fixed frame (3) and a bolt pin (4). The rotary substrate (1) is circular. A plurality of heat-flow sensors (2) are installed on the rotary substrate (1). The connection line of the central points of the heat-flow sensors (2) is superposed with a certain diameter of the rotary substrate (1). The rotary substrate (1) is fixedly connected with the fixed frame (3) through the bolt pin (4). The installation angle of the rotary substrate (1) on the fixed frame (3) can be adjusted. According to the method and the device disclosed by the invention, the condensation performance of the solar disc type condenser is tested; the optical condensing ratio of the solar disc type condenser is evaluated; and the heat-flow density distribution is provided for the use process.

AI Technical Summary

Benefits of technology

This new technology allows us to accurately determine how well things are doing during their production process without having them undergo multiple tests over time at different times. It uses an infrared temperature measurement system that measures the amount of energy being transferred from one part of the material through another part. By measuring this transferring power we get more accurate data about its properties compared with traditional methods like conducting experiments on materials before they were made.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the accuracy and reliability of measuring thermal properties such as temperature and light intensity during solar panellery systems that require efficient conversion from focused solar rays into electricity through a process called thermo sinking (thermophoresis). Current techniques involve either direct measurements or indirect ones like lamberts. Direct measures have limitations because they only provide accurate data but may also result in errors when used alone. Therefore, these existing solutions lack precision and reliable performance.
