Abstract
Description
Technical Field
[0001] The present application relates to the technical field of glass heating, and in particular to a glass heating window. Background Art
[0002] Embedded resistance wire heating technology is a common and effective heating method for heated glass windows. This method achieves uniform heating by embedding tiny resistance wires within the glass. The following is a detailed description of the technology: The basic principle of embedded resistance wire heating is to form thin filaments of high-resistance material and evenly distribute them across the middle layer or backside of the glass. When current passes through the resistance wires, the wires generate heat due to the electrical resistance effect, which in turn heats the entire surface of the glass. The resistance wires are typically made of nickel-chromium alloy, iron-chromium-aluminum alloy, or other high-resistance materials, and have a small diameter to minimize the impact on the appearance and transparency of the glass. The resistance wires are evenly arranged on the glass according to design requirements. They can be fixed in place by spraying, screen printing, or hand placement. The resistance wires are connected to an external power source via connectors. These connectors must withstand high temperatures and high currents and are typically made of metal and insulated with insulating material.
[0003] Embedded resistance wire heating technology for heated glass windows is a common and effective heating method, but the manufacturing process is complex and delicate, requiring the resistance wire to be embedded within the glass to ensure even distribution and a tight bond. While the resistance wire is small, it can still affect the transparency of the glass, especially in applications requiring high transparency. The presence of the resistance wire can create subtle shadows or reflections when light passes through it, affecting the usability of the clear glass. Utility Model Content

The heating plate 300 is attached to the heat-conducting glass 200 along the annular fixing groove 210. This allows the glass to be heated uniformly without obstructing the glass in the middle.

[0037] In one embodiment, the heating plate 300 is attached to the bottom and side walls of the fixing groove 210 of the thermally conductive glass 200. This allows simultaneous heating of the thermally conductive glass 200 in two directions, thereby achieving uniform heating of the thermally conductive glass 200. Specifically, the heating plate 300 is attached to the bottom and side walls of the fixing groove 210 of the thermally conductive glass 200, allowing heating of the thermally conductive glass 200 in both the surface direction and the direction perpendicular to the surface direction of the thermally conductive glass 200.
