The invention discloses a method for researching the heat slow-release law of heterogeneous materials. By using the method for researching the heat slow-release law of heterogeneous materials and the detection device for heterogeneous heat release characteristics of the present invention, a method for inhomogeneous materials is established. The heat release vacuum detection environment eliminates the influence of convection and heat conduction heat transfer methods on the study of heat release characteristics of heterogeneous materials, so that the research target is only one heat transfer method of heat radiation, and the research object is more targeted; at the same time The twin support vector machine is used to establish a prediction model of temperature values at different spatial locations and at different times in the closed cavity, and predict the temperature values of space points that cannot be directly measured and their time-varying curves, reducing the time and material costs of experimental research. Increase the credibility of the research results on the heat release characteristics of heterogeneous materials, and provide scientific experimental and analytical tools for further digging into the heat release laws of floor heating wood floors.
Description
technical field [0001] The invention relates to a research method for the thermal slow-release law of heterogeneous materials, which belongs to the field of thermophysical performance research of heterogeneous materials. Background technique [0002] In homes and offices, wooden flooring is a commonly used material for decoration, decoration and floor heating. When heating in winter, the wooden floor will release heat slowly after being heated. Because the wooden floor is a heterogeneous The internal structure of materials is affected by the composition, arrangement and growth cycle of cells, so it has anisotropic characteristics. To study the mechanism and characteristics of the slow release of heat, it is not possible to simply use the research method of homogeneous materials. A new detection device and detection method for the study of the heat slow release law of the heating floor, so a research method for the heat slow release law of heterogeneous materials is urgently ...
