AI Technical Summary

Problems solved by technology

The coupling results in relatively high cost, difficult to change patterns, large load losses, difficulty maintaining flow for large deflection angles, and small fluid dispersion that makes thermal optimization of the mixing in which the coupling participates difficult

Embodiment Construction

[0024] In particular, the object of the present invention is to provide a fluid diffusion device DD intended to be coupled to an end EC of a duct CD in which a fluid flows.

[0025] In the following, as a non-limiting example, the duct CD and its fluid diffusion device DD are considered for fitting on a motor vehicle such as a car. The fluid is therefore a gas (more precisely air). But the invention is not limited to this application. In fact the present invention relates to any system, apparatus, device, apparatus, or building which may include at least one conduit capable of enabling the Fluid flow that diffuses in the main direction. Accordingly, the present invention relates to conveyances (whether of type (land, sea (or river), or air), equipment (including industrial type equipment), premises, or buildings, and more generally to at least Any system of fluids, whether in liquid, gaseous, or multiphase form, especially blowers, air curtains, jacuzzis and whirlpools, nau...

Abstract

The invention relates to a fluid-diffusion device (DD) which is coupled to an end (EC) of a pipe (CD) in which a fluid flows. The device (DD) includes a main portion (PP), defining a pipe having a cone-shaped inner surface (FI) and comprising an upstream end (EA1) capable of being coupled to the end (EC) of the pipe (CD) and a downstream end (EV1) having an inner cross-section which is larger than that of the upstream end (EA1), and acting means (MA), installed substantially at the interface between the pipe end (EC) and the upstream end (EA1) and arranged such as to act on the fluid by locally reducing cross-section thereof, by separating at least one selected portion of the inner surface (FI), in order to guide the fluid in a selected main direction and with a selected expansion rate.

Description

technical field [0001] The present invention relates to a fluid diffusion device for coupling to a pipe (or conduit) in which a fluid (gas, liquid, or multiphase) flows. Background technique [0002] In some fields (such as the field of vehicles, optionally motorized type of transportation), fluid diffusion devices (or ventilators, or diffusers) are used to diffuse fluids coming from at least Pipelines in one part and / or along selected main directions. [0003] In order to enable the user to select the part of the area where the fluid is desired to diffuse and / or the main direction of diffusion of the fluid, the fluid diffusion device is usually arranged with at least one vane set, which is optionally fitted on a movable part (such as an opening) hemisphere). [0004] These blades are movable parts (optionally movable relative to each other), often of complex shape and therefore difficult to produce, the movement of which often requires interaction with other drive parts (...
