摘要
An adhesive layered backflow preventer laminate, for use in impeding airflow from flowing in a backflow direction through the backflow preventer and a corresponding cooling fan, includes a thin front support layer adhered to a thin backflow flap layer, having a plurality of backflow flaps, which is adhered to a thin rear support layer. Each of the structural layers is adhered to the adjacent structural layer using a respective double-sided adhesive layer, by way of a manufacturing process that avoids the use of costly injection molded parts and machined plastic parts and metal components such as springs and hinges.
說明書
According to an embodiment, a distal side of the third adhesive layer 207 may be further adhered to a proximal side of a fan housing 112a of a cooling fan 112 or fan assembly. Thus, what is described is an adhesive layered backflow preventer 200 that is manufactured, assembled, composed in such a way to be devoid of any relatively costly injection molded and/or machined plastic parts, and devoid of metal components such as springs and/or hinges, by way of assembling a series of relatively or substantially two-dimensional profiles (e.g., alternating plastic and adhesive layers) rather than a set of complex parts.
