Title:
FANLESS EXHAUST DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/045695
Kind Code:
A1
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.
