Technical field
The present invention relates to the resistance to coefficient of heat conductivity checkout equipment technical field of speeding, be specifically related to a kind of device of accelerating coefficient of heat conductivity detection speed.
Background technology
The resistance to coefficient of heat conductivity detector of speeding of vacuum heat-insulating plate: be that detected sample (vacuum heat-insulating plate) is placed in to (upper and lower two plates are respectively hot plate and cold drawing) between detecting instrument two plates, heat is delivered to cold drawing from hot plate by sample, measures the hot-fluid transmitting and comes calculation of thermal conductivity and thermal resistance.Because test chamber length and width are 300*300mm, if want to detect the detection of must opening the door of longer sample, this will certainly cause air to enter cavity, affects testing result accuracy and lengthens detection time simultaneously.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of and forms simply, low cost of manufacture, the device of quickening coefficient of heat conductivity detection speed.
Technical matters to be solved by this invention realizes by the following technical solutions:
A kind of device of accelerating coefficient of heat conductivity detection speed; comprise a protection housing; in described protection housing, be provided with coefficient of heat conductivity test chamber, described coefficient of heat conductivity test chamber internal upper part is provided with hot plate, and bottom is provided with cold drawing; described protection housing is made up of vacuum heat-insulating plate; section is square structure, on described protection housing one side, is provided with a body, and described door body bottom-hinged is on the bottom surface of protection housing; opening of convenient protection housing, solves protection housing inner air flow problem.
Described protection housing is square or rectangular structure, and inner space is large, and each panel links together by adhesive, is convenient to actual fabrication.
The invention has the beneficial effects as follows: the present invention utilizes vacuum heat-insulating plate to make an outer protection shell; stop surveyed area to exchange with extraneous heat; make surveyed area reach original steady state (SS), can expand detection sample length, shorten detection time increases detection accuracy simultaneously.
