Description

Technical Field

[0001] This application relates to the field of window sashes, door sashes or similar components for closing openings, and specifically to a type of insulated glass. Background Technology

[0002] The utility model patent document with announcement number CN221144115U describes a heat-insulating insulated glass, including an aluminum alloy frame. A glass window A is embedded in one side of the interior of the aluminum alloy frame, and a glass window B is embedded in the other side of the interior of the aluminum alloy frame. A hollow layer is provided in the middle of the interior of the aluminum alloy frame. A first coating is applied to one side of the A glass window, and a second coating is applied to one side of the B glass window. A placement groove is opened in the middle of the inner wall of the aluminum alloy frame, and a drying mechanism is engaged inside the placement groove. Mounting holes are arranged in a rectangular array around the inner wall of the aluminum alloy frame.

[0003] The heat-insulating insulating glass described in the aforementioned patent documents mainly relies on the drying mechanism inside the insulating interlayer to adsorb the moisture in the interlayer. However, the internal space of the insulating interlayer is sealed and narrow, and the air convection is limited, making it difficult to ensure that the drying mechanism can effectively adsorb the moisture in the interlayer.

[0021] Reference Figure 1-2 This application proposes an embodiment of the hollow insulating glass, which includes two glass sheets 10 spaced apart and a spacer strip 20 bonded between the two glass sheets 10 by sealant. The spacer strip 20 is provided with a filling cavity 50, which is used to hold a desiccant. The surface of the spacer strip 20 is provided with a guide groove 30, which is connected to the filling cavity 50 through micropores.

[0022] This application provides a flow guide groove 30 on the surface of the spacer strip 20. The flow guide groove 30 is connected to the filling cavity 50 through micropores with a pore size of 0.1-0.2 mm. The flow guide groove 30 increases the contact area between the air and the desiccant in the filling cavity 50. Furthermore, the flow guide groove 30 guides the air to flow in a directional manner into the filling cavity 50, where it is adsorbed by the desiccant, which is beneficial to improving the adsorption effect of the desiccant on water vapor.

[0023] The guide channel 30 is provided with a hydrophilic coating at the connection with the filling cavity 50, which helps to increase the residence time of water molecules and ensure the adsorption effect of the desiccant on water molecules.

[0024] Furthermore, the spacer 20 is made of TPS material. The TPS material gives the spacer 20 a porous structure with pore sizes ranging from 0.1 to 0.2 mm. In another embodiment, the spacer 20 is an aluminum alloy profile. After machining the filling cavity 50 in the aluminum alloy profile, the flow guide groove 30 and micropores connecting the flow guide groove 30 and the filling cavity 50 are machined on the aluminum alloy surface.

[0025] The guide channel 30 is an arc-shaped channel. The cross-section of the guide channel 30 is V-shaped. Referring to the attached figure, the spiral shape of the guide channel 30 can further extend the flow path of water within the guide channel 30, increase the contact time between water molecules and the desiccant, and further improve the adsorption effect on water vapor.

[0026] Furthermore, as a preferred embodiment, the two glass plates 10 are provided with microgrooves 40 on the side near the flow channel 30, and the microgrooves 40 are connected to the flow channel 30.

[0027] When there is a temperature difference between the inside and outside of the glass, the hot air in the hollow interlayer rises along the microgroove 40 on the side with a higher temperature, while the cold air inside the hollow interlayer sinks along the microgroove 40 on the side with a lower temperature and flows into the guide groove 30. This allows the air inside the hollow interlayer to form an airflow circulation along the microgroove 40 by means of the temperature difference, so that the cold air in the hollow interlayer can flow into the guide groove 30 and come into full contact with the desiccant, further improving the drying effect of the desiccant on the air.

[0028] Specifically, the microgroove 40 includes a primary groove 41, a secondary groove 42, and a tertiary groove 43. The primary groove 41 is horizontally disposed on the glass near the surface of the spacer strip 20 so that the primary groove 41 is connected to the guide groove 30. There are multiple secondary grooves 42, which are vertically distributed and one end is connected to the primary groove 41. The other end of each secondary groove 42 is connected to several tertiary grooves 43.

[0029] The design of primary groove 41, secondary groove 42 and tertiary groove 43 increases the contact area between microgroove 40 and hollow interlayer, which is beneficial to further improve the effect of microgroove 40 in promoting air convection.

[0030] Preferably, the microgroove 40 is provided with a hydrophilic coating; the hydrophilic coating can promote the inflow of water molecules in the air into the microgroove 40, thereby improving the drying effect.
