Title:
FLUID TRANSPORT DEVICE, LIQUID COOLING DEVICE, REFRIGERATION DEVICE, AND METHOD FOR DETECTING STATE OF FLUID TRANSPORT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/189577
Kind Code:
A1
Abstract:
This fluid transport device comprises: a fan that rotates to transport a fluid along a flow path; a structure that is provided in the flow path and generates a pressure loss in the flow path due to the fluid passing through the structure; and a detecting unit for detecting a state of the fluid or a state of the structure by monitoring a phenomenon associated with fluctuations in the force exerted on the blades of the fan by the fluid due to the fluid that is transported by the fan along the flow path being disturbed.
