Demisting and deicing windshield uniform and controllable in heating and vehicle

Abstract

The embodiment of the invention discloses a demisting and deicing windshield uniform and controllable in heating and a vehicle. The demisting and deicing windshield uniform and controllable in heatingcomprises: a glass substrate; a first electrode, which is arranged at a first position on one side surface of the glass substrate; a second electrode, which is disposed at a second position differentfrom the first position on a side surface of the glass substrate; a glass heating power supply, which is connected to the first electrode and the second electrode; a conductive film, which is arranged on the side surface of the glass substrate and is connected to the first electrode and the second electrode, and is equipped with a flow guide pattern that forms a flow guide loop between the firstelectrode and the second electrode; and a temperature control circuit, which comprises a temperature measuring element and a temperature control unit connected to the temperature measuring element, wherein the temperature measuring element is arranged on the glass substrate, and the temperature control unit is connected to the glass heating power supply, and the temperature measuring element is arranged on the flow guide loop. The demisting and deicing windshield disclosed by the embodiment of the invention is uniform and controllable in heating, can melt ice and remove snow, and reduces the possibility of heavy loss caused by accidents like glass cracking due to continuous rising of the glass temperature.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a defogging and ice-melting windshield with uniform and controlled heating and a vehicle. Background technique [0002] Usually, vehicles need to work in an environment with large temperature differences. For example, aerial flight equipment such as airplanes flying at high altitudes. Baidu or above. During the flight, the observation window of the aerial flight equipment, such as the windshield of the aircraft, is required to be kept in a continuous observable state, so it cannot cause frost, fog, ice and snow on the observation window due to the large temperature difference. Most of the existing solutions are to install a conductive film on the observation window of the vehicle. The two ends of the conductive film are connected to electrodes and a glass heating power supply, and the observation window is heated by the inherent heating power, so as to quickly remove the frost, fo...

AI Technical Summary

Problems solved by technology

However, most of the disadvantages of this solution are that when the external environment changes no longer have icing or frosting, etc., and when the ambient temperature rises, the observation window of the vehicle will cause the observation window (or windshield) to burn due to the continuous generation of heat. The temperature continues to rise, which may cause the glass to burst

In addition, the continuous rise of glass temperature will also make the glass material itself relatively weak in thermal shock resistance due to different local temperature differences, which will eventually cause uneven heating of the glass surface and easily cause serious consequences such as glass breakage.
