FLUID FLOW DEVICE AND METHOD OF OPERATING SAME

摘要

Provided is a fluid flow device including a flow passage structure including in the interior a micro-channel and an escape flow passage for allowing a fluid to escape from the micro-channel. The micro-channel includes a folded-back flow passage portion that allows the fluid to flow upward before allowing the same to flow downward. The folded-back flow passage portion includes a top portion disposed at the highest position of the folded-back flow passage portion and an upward flow passage portion and a downward flow passage portion with the top portion as a boundary therebetween that allow the fluid to flow upward and downward, respectively, and the escape flow passage is connected to the top portion of the folded-back flow passage portion.

主权项

1. A fluid flow device for performing predetermined processing while allowing a fluid to flow, comprising:
a flow passage structure including in an interior at least one micro-channel for allowing a fluid that is a processing object and at least one escape flow passage for allowing the fluid to escape from the micro-channel; and a discharge switch part configured to be switchable between an allowance state in which the fluid is allowed to be discharged from the escape flow passage and a prevention state in which the fluid is prevented from being discharged from the escape flow passage, wherein the micro-channel includes at least one folded-back flow passage portion that allows the fluid to flow upward before allowing the same to flow downward, the folded-back flow passage portion includes a top portion disposed at a highest position of the folded-back flow passage portion, an upward flow passage portion connected to the top portion and allowing the fluid to flow upward and flow into the top portion, and a downward flow passage portion connected to the top portion and allowing the fluid flowing in from the top portion to flow downward, and the escape flow passage is connected to the top portion or a portion adjacent thereto of the folded-back flow passage portion.
