Device and method for rapidly testing heat conductivity coefficient of vacuum insulated panel

Abstract

The invention discloses a rapid testing device for the heat conductivity coefficient of a vacuum insulation panel and a testing method of the rapid testing device, relates to the technical field of testing of the heat conductivity coefficient of the vacuum insulation panel, and solves the problem that labor is consumed when a plurality of vacuum insulation panels are detected. The positioning mechanism comprises guide rails and positioning plates vertically sliding on the guide rails, one positioning mechanism is provided with the two guide rails facing oppositely, a positioning cavity is reserved between the positioning plates of the two guide rails, and the lower ends of the positioning plates are connected with a bearing plate. A supporting assembly used for supporting the positioning plate is installed in the guide rail, the upper end of the positioning plate is fixedly connected with a first clamping hook, the lower end of the positioning plate is fixedly connected with a second clamping hook, when the heat flow sensor leaves the vacuum heat insulation plate, the positioning plate abutting against the supporting block slides in the direction away from the heating plate, and the second clamping hook slides into the first clamping hook. The vacuum insulation panel can be kept in a vertical state to be located between the heating plate and the heat flow sensor, and manpower is saved.

Description

technical field [0001] The present application relates to the technical field of testing the thermal conductivity of a vacuum insulation panel, in particular to a rapid testing device and a testing method for the thermal conductivity of a vacuum insulation panel. Background technique [0002] As a high-efficiency thermal insulation material, vacuum insulation panels are widely used in the fields of home appliance insulation, cold chain logistics, and building insulation. Thermal conductivity is one of the important indicators for judging the thermal insulation capability of vacuum insulation panels. During the testing process, in order to ensure the qualified rate of vacuum insulation panels, it is necessary to measure the thermal conductivity of multiple vacuum insulation panels. The thermal conductivity test of vacuum insulation panels generally uses a thermal conductivity tester. [0003] At present, the thermal conductivity measuring instrument is as described in the pa...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that in the process of testing the vacuum insulation panel, it is necessary to hold the vacuum insulation panel with hands, and only when the vacuum insulation panel is clamped by the heating plate and the heat flow sensor can the hand be released; the hydraulic machine leaves the vacuum insulation panel with the heat flow sensor When the vacuum insulation panel falls down and falls on the heat flow sensor, the vacuum coating of the vacuum insulation panel may be damaged. Therefore, after the test is completed, it is necessary to hold the vacuum insulation panel by hand. When the heat flow sensor leaves the vacuum insulation panel, the vacuum The insulation board can only be pulled out, so the whole test process needs human assistance in order to protect the vacuum insulation board. When testing multiple vacuum insulation boards, it is more labor-intensive.
