Fan
First Claim
1. A fan, comprising:
- blowing units, each of said blowing units including a square-shaped hollow casing, an electric motor incorporated into the casing and an axial impeller coupled to the motor for generating an air flow from an inlet of said casing toward an outlet of said casing;
said casing having a first open end forming the inlet and a second open end opposite to the first open end wherein the second open end is provided with nozzles; and
a guide which projects into the casing to arrange the nozzles in a parallel pattern, in a slit shape and in rows;
said blowing units coupled together at adjacent sides thereof to form a row of blowing units;
wherein each of said blowing units has the inlet provided with a bellmouth which surrounds the axial impeller; and
means for blocking a space between each bellmouth and each casing to thereby block an air flow path through the space and separate the space from the air flow generated by the axial impeller.

Abstract
A fan comprising: blowing units, each including a squarely hollow casing, an electric motor incorporated into the casing and an axial impeller coupled to the motor for generating an air flow from an inlet toward nozzles; the casing having one end opened to form the inlet and the opposite end opened to form the nozzles; and a guide which projects into the casing to arrange the nozzles in a parallel pattern, in a slit shape and in rows; wherein the blowing units are coupled together at adjacent sides thereof to be arranged in a row, each unit has the inlet provided with a bellmouth which surrounds impeller, and a space between each bellmouth and each casing is separated from an air flow path with the air flow generated by the impeller passing therethrough.
