Condensation and Respiration in Two Wheeler Instrument Cluster 2022-28-0032
Due to the major temperature difference between the inner cabin and the outer environment of the two-wheeler instrument cluster, there will be visible condensation on the inner side of the lens, giving rise to a cloudy patches. This results in obstructing visibility and is commonly observed in the cluster which is directly exposed to the outer environment. To avoid condensation, an anti-fog layer is applied on the inner side of the lens. After a certain amount of water absorption, the de-lamination of a layer from the glass (PMMA) substrate occurs leading to the formation of a white patch. The current study proposes a concept design to avoid the condensation of water vapor by reducing its concentration in the cluster, with the help of proper air circulation using air vents placed at different heights on the lower surface of the instrument cluster. For the purpose of study instrument cluster virtual model has been taken and the computational analysis of the same is presented.
