Controlling means for one dimension space temperature field of plate type fabric heat preserving device

Abstract

The invention discloses a method for controlling the spatial temperature field of a plate type temperature preserver for fabrics, which corrects the wrong method in the prior test standards from China, America and Japan. At the inner surface of a test plate and a base plate, a temperature sensor is placed respectively, wherein, one temperature sensor displays the temperature of the inner surface of the test plate, and a heating control system controls the temperature of the inner surface of the test plate so that the max. temperature difference between this temperature and the temperature of the inner surface of the test plate after the test plate becomes steady is 0.3 centigrade. The invention realizes ''one-degree temperature steady field'' that the test plate only radiates upward, overcomes the heat transmission between the test plate and the base plate, so as to ensure the singularity of the heat transmitting direction, and the higher accuracy of the test results of heat preservation.

Description

technical field [0001] The invention relates to a method for controlling the temperature field of one degree of space of a flat-plate fabric heat preservation instrument. The heat preservation instrument is a special instrument mainly used for measuring the heat preservation performance of various fabrics, cotton wool, leather and other clothing materials. Background technique [0002] The flat-plate heat preservation instrument mainly includes a test plate, a protective plate and a bottom plate with heating elements installed inside, collectively referred to as a hot plate, and supporting temperature display and control devices. Wherein, the protection board is installed around the test board and is in the same plane as the test board. The bottom plate is set under the protective plate and the test plate, and they are separated by a wooden frame, and form several air chambers with the surrounding wooden frames or frames made of other materials and heat insulating materials ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, due to the current control method of "the temperature between the bottom plate and the test plate is consistent or close to the same", it cannot guarantee that the temperature of the bottom plate and the inner surface of the test plate are consistent or close to the same

This temperature control method cannot overcome the conduction of heat between the test board and the bottom board, and cannot form a "one-degree space temperature stable field" in which the test board only dissipates heat in one direction, so it is difficult to accurately test the thermal insulation of clothing materials.
