Color and heat absorption efficiency experimental instrument

Abstract

The invention relates to a color and heat absorption efficiency experimental instrument. The color and heat absorption efficiency experimental instrument is characterized in that temperature sensors are fixed on the bottom surface of the box body; annular absorber plates are arranged above the temperature sensors; the lower surface of the each annular absorber plate is tightly attached to the upper surface of the corresponding temperature sensor; a rotating shaft is arranged at the center of the each annular absorber plate; a jagged circular disk is fixed on the each rotating shaft; the each annular absorber plate is provided with sector subregions; the color of each sector subregion is different; a bulb and a switch for controlling the bulb are arranged on the side wall of the box body; the temperature sensors are connected with an analog-to-digital conversion module through connection lines; the analog-to-digital conversion module is connected with a computer through a data line. Thecolor and heat absorption efficiency experimental instrument can perform digitalized analysis and comparison on the color and heat absorption efficiency experiment, can synchronously compare the heatabsorption efficiency of a plurality of colors, can improve the precision of the experiment, is convenient to operate, is not influenced by weather, is visual in the experimental result, and has small error.

Description

technical field [0001] The invention relates to a teaching device, in particular to a color and heat absorption efficiency experiment instrument. Background technique [0002] Studying the heat absorption capacity of different colors is a very important knowledge point in elementary school science, but the several methods used are cumbersome and have their own shortcomings. One of the methods is to use a convex lens to irradiate different colors of paper to generate high temperature, and compare the speed of the paper to ignite. This method requires precise adjustment of the focus of the lens, which is greatly affected by personal operation and weather. Errors are also difficult to eliminate, the effect of the experiment is not good and accidents of burns are prone to occur. Contents of the invention [0003] In order to solve the above problems, the present invention provides a color and heat absorption efficiency tester. [0004] The technical solution adopted by the p...
