1. A fluid atomizer with a plurality of helical inlet channels, wherein the fluid atomizer is configured to atomize a fluid and convert the fluid into a spray of droplets, the fluid atomizer comprises a fluid inlet and a swirl chamber, wherein the fluid inlet and the swirl chamber are two independent chambers, and a flow passes through the two independent chambers, the fluid atomizer transforms the fluid into a spray dispersion by atomizing the fluid after the fluid is collected in a center of the fluid inlet after a centrally coming fluid is dispersed by forming a swirl, wherein
the fluid inlet allows the fluid to be transformed into a spray form, wherein the fluid comes from a main fluid line and is to be transferred to the helical inlet channels and the swirl chamber,
the plurality of helical inlet channels are located on the fluid inlet, the plurality of helical inlet channels extends from the fluid inlet towards the swirl chamber helically, the plurality of helical inlet channels allows the fluid accumulated at the fluid inlet to be atomized and transferred to the swirl chamber through the plurality of helical inlet channels, the plurality of helical inlet channels provides to receive the fluid from the center of the fluid inlet and to access the swirl chamber at a tangential or predetermined angle with a swirl property,
the swirl chamber is connected to the plurality of helical inlet channels and has a circular form, the swirl chamber causes the fluid to enter from the fluid inlet at a tangential or predetermined angle to create a swirl and directs the swirling fluid to a fluid outlet, the swirl chamber can change a rotation speed and flow speed of the fluid coming from the plurality of helical inlet channels in a helical swirl flow characteristic by a geometric form of the swirl chamber and plurality of helical inlet channels, wherein, at connections between the plurality of helical inlet channels and the swirl chamber, the plurality of helical inlet channels are aligned with a plane that is perpendicular to a central axis of the circular form of the swirl chamber,
the fluid outlet is located at a lower end of the swirl chamber, the fluid outlet can suck air in the swirl chamber due to a characteristic of the flow inside and a pressure difference with an external environment, the fluid outlet provides an outlet of the fluid in a form of conical fluid film or in a form of conical spray form by atomizing the droplets with the air, wherein the fluid outlet sucks the air.
