Multi-part fluid flow structure

摘要

In one example, parts to be assembled into a fluid flow structure include: a first part having a first opening therein and a first adhesive bonding surface surrounding the first opening; a second part having a second opening therein and a second bonding surface surrounding the second opening; and the first and second bonding surfaces are each configured, when the parts are assembled for bonding and an adhesive is squished between the parts, to create a capillary force along the bonding surface urging adhesive away from the opening.

主权项

1. An assembly for carrying fluid from a first part to a second part, comprising:
a first structure having a first conduit for receiving fluid from the first part, a first opening from the first conduit and a first bonding surface surrounding the first opening, the first opening transitioning along a first curve from a smaller interior part of the first opening to a larger exterior part of the first opening that forms at least part of the first bonding surface; a second structure defining a second conduit for receiving fluid from the first conduit and carrying fluid toward the second part, a second opening to the second conduit and a second bonding surface surrounding the second opening, the second opening aligned with the first opening and transitioning along a second curve from a smaller interior part of the second opening to a larger exterior part of the second opening that forms at least part of the second bonding surface; and an adhesive joining together the first and second structures at the first and second bonding surfaces.
