Problems solved by technology

[0002] In physical caloric experiments, it is very necessary to have a box that can isolate heat exchange from the outside world. To ensure the accuracy of the data, it is necessary to minimize the loss of heat and reduce the interference of external heat, and the heat insulation performance of general incubators cannot meet the needs

Abstract

The invention pertains to the field of experiment teaching aids and more particularly relates to a teaching aid for measuring the heat insulation efficiency of objects, which is composed of an iron shell (1), a foam insulation layer (2), reflector glass (3), vacuum glass (4), a thermometer (5), a water tank (6), an electric heating appliance (7), water (8) and an object (9) to be measured. The teaching aid of the invention has simple structure and convenient operation, solves the problem of lacking similar teaching aids in the physics teaching and causes the teaching to be more overall and vivid.

Description

technical field [0001] The invention belongs to the field of experimental teaching aids, in particular to a teaching aid for measuring the heat insulation efficiency of objects. Background technique [0002] In physical caloric experiments, it is very necessary to have a box that can isolate heat exchange from the outside world. To ensure the accuracy of the data, it is necessary to minimize the loss of heat and reduce the interference of external heat, but the heat insulation performance of general incubators cannot meet the needs. Contents of the invention [0003] The purpose of the invention is to design a teaching aid for measuring the heat insulation efficiency of objects. [0004] The invention provides a teaching aid for measuring the heat insulation efficiency of an object, which is composed of an iron shell, a foam insulation layer, a mirror glass, a vacuum glass, a thermometer, a water tank, an electric heater, water and a measured object. [0005] A teaching ...
