Problems solved by technology
Although the two laws are summarized through a large number of experiments, there are certain difficulties in the experimental verification in general laboratories. At present, there are no experimental demonstration instruments related to the heat balance process, which makes it difficult for students to thoroughly understand the physical nature of the heat balance law.

The invention provides a heat balance process visualization experimental device. A base is provided with a first water tank, a second water tank and a third water tank which are integratedly connected, the upper end covers of the first water tank, the second water tank and the third water tank are provided with water tank cover plates and the surfaces of the first water tank, the second water tank and the third water tank are provided with a heat insulation layer. The left side base of the first water tank is provided with a first bracket which is provided with a first semiconductor laser and a light beam splitter at the emergent light direction of the first semiconductor laser. The back side base of the first water tank is provided with a third bracket which is provided with a third mirror. The front side base of the third water tank is provided with a second bracket which is provided with a second semiconductor laser. A laser beam transversely goes through the third water tank and the first water tank at a position close to the right side wall of the third water tank and is projected to the third mirror. The third mirror reflects the laser beam to the light screen. The heat balance process visualization experimental device has the advantages of a simple structure, low cost, convenient carrying, intuitive demonstration, a good demonstration effect and can be used as a demonstration experiment instrument of heat transfer theory teaching.
Description
technical field [0001] The invention belongs to the technical field of heat transfer experiment instruments, and in particular relates to heat balance process experiment equipment or devices. Background technique [0002] The four laws of thermodynamics are the basis of the macroscopic theory of thermal phenomena. The zeroth law of thermodynamics, also known as the law of heat balance, is expressed as: If A and B, B and C are in thermal equilibrium, A and C are also in thermal equilibrium with each other. The strict definition of temperature, the core concept in thermodynamics, is based on this law. The zeroth law of thermodynamics focuses on the transferability of heat balance, but R-H Fuller only stipulates that the temperature is equal according to the transferability of heat balance to the definition of temperature, and cannot compare the temperature, nor can it judge the unbalanced system The direction of heat flow between. Therefore, the zeroth law only gives the re...
