Abstract

The present invention discloses control device for one degree spatial temperature field of a flat type fabric heat preservation instrument. An experiment plate (4) and a bottom plate (1) are respectively disposed with two or more temperature sensors. The temperature sensors are respectively connected with singlechip. The invention conquers the mutual heat conduction between the experiment plate and the bottom plate, ensures the uniqueness of the heat transfer direction of the experiment plate and makes the heat preservation test result more accuracy.

Description

technical field [0001] The invention relates to a control device for one-degree space temperature field 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, leather and other clothing materials. Background technique [0002] The flat-type heat preservation instrument is generally composed of three parts: a heat preservation cover, a temperature control device fixed under the heat preservation cover, and an electric control device connected to the temperature control device through a line. Wherein the current temperature control device is generally provided with a temperature sensor on the experiment board and the base board respectively. Or use multiple temperature sensors for simple cascading control. [0003] It has been found in practice that the above-mentioned temperature control method cannot overcome the conduction of heat between t...
