The utility model content
Technical problem to be solved in the utility model provides a kind of hot-plate instrument for the fabric thermal performance test, can improve the measurement accuracy of fabric thermal resistance.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of hot-plate instrument for the fabric thermal performance test is provided, comprise and measure hot plate and last hot backplate, described hot backplate is positioned at the periphery of measuring hot plate, also be provided with thermal insulation barriers between described measurement hot plate and the last hot backplate, hot backplate in being provided with down under the described measurement hot plate, describedly be provided with following hot backplate under hot backplate, describedly be provided with thermal insulation barriers between hot backplate and the following hot backplate in down; Described measurement hot plate, go up hot backplate, down in hot backplate and following hot backplate inner surface be provided with heater element; Described measurement hot plate, go up hot backplate, be equipped with temperature sensor on hot backplate and the following hot backplate in down.
Described measurement hot plate and the hot backplate of last hot backplate and described bottom and down in be provided with cystosepiment in the cavity between the hot backplate.
Described heater element is heating film.
The adjacent setting of temperature sensor on temperature sensor on the described measurement hot plate and the last hot backplate; Described down in the position of temperature sensor on position and measurement hot plate and the last hot backplate of temperature sensor on hot backplate and the following hot backplate corresponding one by one.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model make measure hot plate with down between the hot backplate, the temperature difference that may exist between last hot backplate and the following hot backplate further dwindles, completely cut off heat radiation and the thermal convection between the hot plate up and down simultaneously, further reduce and occur in the heat interchange of measuring between hot plate and each the hot backplate, particularly under the blowing condition, make the measurement hot plate more accurate by fabric power, improve the measurement accuracy of fabric thermal resistance.
