Problems solved by technology

[0005] In particular, it should be pointed out that the energy-saving glass is made into a small test piece, and the data detected by a general material thermal conductivity tester cannot truly reflect the heat insulation performance and product quality of the actual product of energy-saving architectural glass.

Embodiment approach

[0017] Accompanying drawing 1 is a structural representation of the present invention.

[0018] The frame (1) is equipped with a lifting glass carrier (17) that can be adjusted up and down according to the size of the glass, and a vacuum suction cup (10) that fixes the glass (0) to be tested. Cold box (11), refrigerating unit (18) are also all fixed on the frame. Internal and external protection heat boxes (4), (7) are installed on the movable dolly (2) on the frame track. The vacuum suction cup fixing device (10) can ensure that the glass is closely bonded to the inner and outer protective heat boxes and cold boxes, so as to prevent leakage and heat dissipation of the contact parts.

[0019] The inner protective heat box (7) is an airtight heat-insulating box made of materials such as high heat-insulating materials such as polyurethane hard foam plastics and polystyrene hard foam plastics, or has a structure with a suitable surface layer and foam plastics in the middle . T...

Abstract

A device special for determining stable state thermal resistance of architecture glass which is a necessary determining device for quality control and product acceptance in energy-saving architecture glass produce is provided. The present invention comprises of heat flux sensor, internal and external guarding heat-box, cold-box (including refrigerating unit), precision temperature measurement and computer data collecting process system, and frame mounted rise-and-fall glass carrying stage and vacuum acetabula glass fixation mechanism. The present invention is not only used for detecting state thermal resistance of energy-saving architecture glass such as vacuum glass, hollow glass, and so on, but also used for detecting heat insulation and heat preservation capacity of other plate architecture material such as polystyrene board, steel (aluminium) plastic compound heat preserving board and so on.

Description

Technical field [0001] The invention relates to a device for measuring the thermal insulation performance of architectural glass, especially a special device for measuring the steady-state thermal resistance of energy-saving architectural glass. Background technique [0002] Building energy conservation is an important measure to save energy and reduce environmental pollution. In building energy consumption, the heat loss of window glass and curtain wall glass accounts for a large proportion. The research, development and application of energy-saving glass such as insulating glass and vacuum glass provide architectural glass products for doors, windows and curtain walls with good thermal insulation performance and remarkable energy-saving effect for building energy conservation. [0003] So far, the only instrument for measuring the heat transfer coefficient of architectural glass invented by CN 200620131674.6 can be used for thermal insulation performance testing of archit...
