Card spacer type convection blocker

Abstract

The present invention adopts a card-type spacer-type convection barrier, which includes two or more light-transmitting plates forming an interlayer. The double-layer light-transmitting plates are sealed and connected to the spacers around the light-transmitting plates, transparent fins, and fin installation barriers. It is characterized in that the spacers form a rectangular side frame, and the fins are installed on the retaining strips and the spacers are buckled through the slots. Molecular sieves or hygroscopic agents can be placed in the cavity formed between the two, and the transparent wings are vertically and parallelly arranged on the upper and lower sides. The lower fins are installed between the retaining bars. Since the above-mentioned spacers are set to form a rectangular side frame, and the fins are installed and fastened with the spacers through the slots, the manufacturing and installation process is simpler and the cost is reduced; at the same time, transparent wings are vertically and parallelly arranged on the upper, The lower fins are installed between the retaining bars, so the downward tension or gravity can be used to hang the fins, which can effectively fix the fins and solve the problem of easy sagging of the middle part of the fins when the width of the light-transmitting sandwich panel is large. It causes visual discomfort, thereby improving the reliability of use and expanding the application range of width. Compared with the existing technology, the vertical and parallel arrangement of the fins can limit the upper and lower convection and front and rear backflow of the heated air. The thermal insulation performance and light transmittance of the light-transmitting plate are improved in the same range.

Description

technical field [0001] The invention relates to the technology of a double-glass card-type spacer-type convection blocker for building heat-preservation and light-transmitting partitions. technical background [0002] Energy saving and heat preservation is a basic requirement for various light-transmitting heat-insulation panels in the construction field, such as doors and windows. As a light-transmitting and heat-insulating material, such as the honeycomb insulation window made of small-diameter transparent glass tubes glued in parallel to the axis of the double-layer glass that has appeared in the international market, or the heat insulation of the honeycomb made of transparent polymer materials Windows, in order to obtain higher heat insulation performance and light transmittance. However, the products manufactured by this method are complex in processing technology, high in cost, large in heat capacity and heavy in weight, and have a large loss in relative light transmi...

Problems solved by technology

However, there are still some shortcomings in the transparent fin barrier set in the horizontal direction: because the sheet strips are distributed along the vertical direction and parallel to the horizontal plane, when the width of the light-transmitting sandwich panel is large, it is easy to produce a gap in the middle part of the sheet strips. Drooping, causing visual discomfort, which limits the increase in its width; in addition, the sheet strips are fixed through the grooves on the side strips, or the parallel support brackets composed of sliding strips, and the side strip grooves adopt sliding strips or flexible steel cable slides, which brings inconvenience to processing and installation. The installation requires a lot of manpower and a long cycle. The setting of desiccant is not considered in this structure. Therefore, a greater degree of improvement on
