Description

Technical Field

[0001] This utility model relates to the field of electrothermal glass plate technology, and in particular to an electrothermal glass plate that improves the electrothermal radiation conversion rate. Background Technology

[0002] Existing electrothermal glass panels mostly employ a single-layer substrate structure, where heat generated by the heating element is easily lost in non-radiative directions (as shown below), resulting in a low electrothermal-radiative conversion rate. Although some products attempt to improve efficiency by optimizing the heating layer material or coating, the lack of a design to construct a heat reflection and recovery system at the mechanical structure level fails to fundamentally solve the problem of heat loss to non-radiative areas. This limits the utilization rate of electrothermal energy and makes it difficult to meet the application requirements of high radiation conversion rates. Therefore, we propose an electrothermal glass panel to improve the electrothermal-radiative conversion rate. Utility Model Content

By setting a reflector plate between the upper and lower base layers, combined with a corrugated structure and an infrared reflective coating, heat lost in the non-radiative direction can be reflected back to the thermal radiation surface of the upper base layer, significantly improving the conversion efficiency of electrothermal energy to radiation energy.

Example

[0013] like Figures 1-3 As shown, an electrothermal glass plate for improving electrothermal radiation conversion efficiency includes an upper base layer 1, a lower base layer 2, and a reflector 3. The reflector 3 is located between the upper base layer 1 and the lower base layer 2. The outer surface of the upper base layer 1 is a heat radiation surface 11. Support columns 31 are provided between the reflector 3 and both the upper base layer 1 and the lower base layer 2, and the reflector 3 is arranged parallel to both the upper base layer 1 and the lower base layer 2. Both the upper base layer 1 and the lower base layer 2 are high-temperature resistant transparent glass, and the single-layer thickness of both the upper base layer 1 and the lower base layer 2 is four mm. It has good thermal conductivity and light transmittance. The reflector 3 is coated with an infrared reflective coating and has a sinusoidal corrugated shape. The reflector 3 is located between the upper base layer 1 and the lower base layer 2. Its surface is coated with an infrared reflective coating and has a sinusoidal corrugated shape. This corrugated structure increases the effective reflection area and can form multi-directional scattering when heat is reflected, thereby improving the reflection efficiency. The support columns 31 are hexagonal prisms arranged in a square array. The distance between the center plane of the reflector 3 and the inner surface of the upper base layer 1 is one-third of the total distance between the upper base layer 1 and the lower base layer 2. Support columns 31 are provided between the reflector 3 and both the upper base layer 1 and the lower base layer 2. These support columns 31 are hexagonal prisms arranged in a square array, with a center-to-center distance of 25mm between adjacent support columns 31, a diameter of 3mm, and a height of 6mm. The support columns 31 ensure that the reflector 3 is parallel to both the upper base layer 1 and the lower base layer 2. Furthermore, the distance between the center plane of the reflector 3 and the inner surface of the upper base layer 1 is one-third of the total distance between the upper base layer 1 and the lower base layer 2. This layout optimizes the heat reflection path and further enhances the reflection effect. Both the upper base layer 1 and the lower base layer 2 have edge stepped connecting grooves 12 at their edges. The lower base layer 2 and the upper base layer 1 have corresponding edge stepped connecting grooves 12. A silicone sealing ring 13 is provided between the two connecting grooves 12 for a sealed connection. Both the upper base layer 1 and the lower base layer 2 have edge stepped connecting grooves 12 at their edges. The lower base layer 2 and the upper base layer 1 have corresponding edge stepped connecting grooves 12. A silicone sealing ring 13 is provided between the two connecting grooves 12 for a sealed connection, forming a sealed reflective cavity, blocking air convection and preventing heat loss to the outside.

[0014] After assembly, the glass heating plate will be polished with a sander, resulting in a higher electrothermal radiation conversion rate.
