Multiple heat transfer teaching confederates method

Abstract

The invention relates to a teaching experiment combined method used to multinomial heat transfer theory. With combining and transforming the multinomial heat transfer theory experiment box, the material thermal conductivity factor can be measured using the pipe / flat steady heat conduction method or the flat unsteady heat conduction method. It can also be used to measure the natural-convection heat transfer factor of the vertical / horizontal plate or the vertical / horizontal pipe in the infinite or finite space, to measure the heat transfer cofficient of the forced convection when air passes through the single tube crosswisely or the flat endwisely, to measure the normal emissing ability of different materials using the comparative method, and to process many other multinomial heat transfer theory experiments. In addition, the relevant flow field can be observed by the smoke.crosswise The target of the experiment teaching can be reached perfectly with a low cost.

Description

technical field [0001] The invention relates to a teaching experiment method, in particular to a teaching experiment method of heat transfer. Background technique [0002] At present, in the teaching experiments of heat transfer in schools, the students basically observe the experimental phenomena, record the data and complete the report according to the experimental instruction book and pre-installed experimental devices and instruments through the teacher's explanation. Due to the large number of experimental items in the teaching of heat transfer, it is necessary to use various experimental equipment, the comprehensiveness of the experiment is poor, and the equipment is often large, the mobility is poor, the number of sets is limited or even only one set, and it is difficult for students to rotate in a short period of time, so The synchronization with the curriculum is not good, which affects the students' understanding of the curriculum. In additi...
