Fanless exhaust device

Abstract

A fanless exhaust device according to the present invention disclosed herein comprises: a main body part which has a first suction port formed on one side, an overall exhaust port formed on the other side, and second suction ports formed on facing surfaces between the first suction port and the overall exhaust port; a first fan installed in the first suction port and driven by a driving force so as to suction air through the first suction port; second fans embedded and installed in the second suction ports and driven by a driving force so as to exhaust the suctioned air through the second suction ports; and an airflow path interference-preventing part which is provided inside the main body part so as to prevent interference between the airflow path of the first fan and the airflow paths of the second fans. According to the present invention, an air pressure difference is generated due to the Bernoulli effect when the first and second fans operate, whereby nearby air above and below, to the left and right, and behind is suctioned, and thus, the present invention has excellent suction efficiency. Since interference between the airflow path of the first fan installed in the first suction port and the airflow paths of the embedded and installed second fans is prevented by the path interference-preventing part provided inside the main body part, air can be exhausted by the second fans, embedded and installed on the second suction ports-side, without hindrance even when the capacity of the first fan is large. Also, the present invention has the effect that a wide range of exhausting is enabled by also suctioning nearby air through the second suction ports.

1 . A main body having a first inlet formed on one side and an entire exhaust port formed on the other side, and a second inlet formed on the opposite surface between the first inlet and the entire exhaust port, installed on the first inlet to the first inlet A first one driven by a driving force to suck air through, a second one driven by a driving force so as to be buried in the second suction port and exhaust the air sucked through the second suction port, and the body portion provided inside, of the first fan
 A fanless exhaust system comprising a; wind path interference preventing unit preventing the wind path and the wind path of the second fan from interfering with each other.   
     
     
         2 . The fanless exhaust device according to  claim 1 , wherein the wind path interference prevention unit changes the direction of the wind introduced from the second inlet by a partition spaced apart from the inner wall surface of the main body. 
     
     
         3 . A fanless exhaust system comprising a; wind path interference preventing unit preventing the wind path and the wind path of the second fan from interfering with each other. 
     
     
         4 . The fanless exhaust device according to  claim 1 , wherein the capacity of the first fan is greater than that of the second fan.
