Problems solved by technology

[0003] It can be seen that the current teaching and experimental equipment for natural convection heat transfer is still in the traditional framework, that is, the placement of tubes or plates is fixed, and design experiments cannot be performed conveniently and flexibly; The measurement form is realized by the combination of many electronic instruments
Such a device does not have the function of developing and designing experiments, and cannot realize the modularization and intelligence of measurement methods and the integration of equipment. It is time-consuming and labor-intensive during the experiment process, and a lot of time and energy are spent on simple and cumbersome instrument operation training.

Abstract

A heat transfer test device of air natural convection for large space external pipe consists of external pipe headstock, control and collection analyzer and computer. It is featured as forming said headstock to be frame structure in rectangular solid shape, hanging the heating external pipe with thermocouple at its surface on horizontal beam of headstock, connecting thermocouple to control and collection analyzer and computer for realizing real time detection.

Description

technical field [0001] The invention relates to a testing and experimental device for heat transfer natural convection heat transfer, in particular to an experimental device for air natural convection heat transfer in a large-space outer tube. Background technique [0002] The phenomenon of natural convection heat transfer is a common phenomenon in nature, and it is also one of the principle phenomena widely used in engineering and scientific circles. It is of great significance to study the law of natural convection of the outer tube in the air. Some well-known scholars in the field of heat transfer have successfully sorted out the natural convection heat transfer of external tubes placed horizontally in a large space into an experimental correlation. content. Many universities use self-made equipment to complete the convective heat transfer teaching experiment device of the swept circular tube. For example, Tsinghua University, Tianjin University, Beijing Petroleum Univ...
