Definitions
- the present disclosure relates to a fan, and more particularly, to a fan configured to discharge air in two directions.
- An object of the present disclosure is to provide a fan adapted for more various applications.
- a fan includes: a fan housing including at least one intake part and at least two discharge parts; and a rotatable blower in the fan housing the blower introducing air through the intake part and discharging the air through the discharge part, wherein minimum distances (D1)(D3) between an inner surface of the fan housing and an outer surface of the blower in upstream ends of the discharge parts in a rotation direction of the blower are greater than mininum distances (D2) (D4) between the inner surface of the fan housing and the outer surface of the blower in downstream ends of the discharge parts, and the mininum distance (D1)(D3) between the inner surface of the fan housing and the outer surface of the blower in the upstream end of one of the discharge parts in the rotation direction of the blower is greater than the minimum distance (D2)(D4) between the inner surface of the fan housing and the outer surface of the blower in the downstream end of another of the discharge parts adjacent in an opposite direction to the
- a fan in another example, includes: a fan housing including at least one intake part and at least two discharge parts; and a rotatable blower in the fan housing the blower introducing air through the intake part and discharging the air through the discharge part, wherein cross-sectional flow areas between an inner surface of the fan housing and an outer surface of the blower in upstream ends of the discharge parts in a rotation direction of the blower are greater than cross-sectional flow areas between the inner surface of the fan housing and the outer surface of the blower in downstream ends of the discharge parts, and the cross-sectional flow area between the inner surface of the fan housing and the outer surface of the blower in the upstream end of one of the discharge parts in the rotation direction of the blower is greater than the cross-sectional flow area between the inner surface of the fan housing and the outer surface of the blower in the downstream end of another of the discharge parts adjacent in an opposite direction to the rotation direction of the blower.
- a fan adapted for more various applications.
- FIG. 1 is a perspective view illustrating the fan 100 according to the embodiment.
- FIG. 2 is a cross-sectional view according to the embodiment.
- the fan 100 includes a fan housing 110 and a blower 120.
- the fan housing 110 includes an intake part 111, a first discharge part 113, and a second discharge part 115.
- the blower 120 is rotatable in the fan housing 110 and radially discharges axially introduced air.
- the intake part 111 is provided to one surface or two surfaces of the fan housing 110, and air is introduced through the intake part 111.
- the first discharge part 113 and the second discharge part 115 are provided to the outer surface of the fan housing 110 in a manner where the first discharge part 113 and the second discharge part 115 are spaced a predetermined angle from each other.
- the fan 100 may be referred to as a two-way fan adapted to discharge air in different directions from each other through the first discharge part 113 and the second discharge part 115.
- the first discharge part 113 and the second discharge part 115 must satisfy the below inequalities.
- the above conditions (1) and (2) must be satisfied to discharge air through the first discharge part 113 and the second discharge part 115.
- the condition (3) is substantially satisfied to secure the amount of air through the first discharge part 113 and the second discharge part 115.
- the ratio of air discharged through the first discharge part 113 and the second discharge part 115 is controlled by changing various conditions. That is, the ratio of air discharged through the first discharge part 113 and the second discharge part 115 is controlled by controlling the central angle A4 between the upstream end of the first discharge part 113 and the downstream end of the second discharge part 115, or the central angle A2 between the downstream end of the first discharge part 113 and the upstream end of the second discharge part 115.
- the ratio in the amount of air discharged through the first discharge part 113 and the second discharge part 115 is substantially controlled by controlling the area of the first discharge part 113 or the area of the second discharge part 115.
- the ratio in the amount of air discharged through the first discharge part 113 and the second discharge part 115 is controlled by controlling a difference in the minimun distances between the upstream end and the downstream end of the first discharge part 113, and the outer surface of the blower 120, and/or by controlling a difference in the minimum distances between the upstream end and the downstream end of the second discharge part 115, and the outer surface of the blower 120.
- the ratio in the amount of air through the first discharge part 113 and the second discharge part 115 is controlled by controlling a difference in the minimum distances between the upstream end of the first discharge part 113 and the downstream end of the second discharge part 115, and the outer surface of the blower 120, and/or by controlling a difference in the mininum distances between the upstream end of the second discharge part 115 and the downstream end of the first discharge part 113, and the outer surface of the blower 120.
- the ratio in the amount of air discharged through the first discharge part 113 and the second discharge part 115 can be controlled by changing various conditions of the fan 100. For example, when the central angle A4 between the upstream end of the first discharge part 113 and the downstream end of the second discharge part 115 is increased relative to the central angle A2 between the downstream end of the first discharge part 113 and the upstream end of the second discharge part 115, the ratio of the air discharged through the first discharge part 113 to the air discharged through the first discharge part 113 and the second discharge part 115 is increased. In addition, the air discharged through the second discharge part 115 is increased relative to the air discharged through the first discharge part 113, by relatively reducing the area of the first discharge part 113.
- the mininum distances between the upstream end and the downstream end of the first discharge part 113, and the outer surface of the blower 120 are increased, the ratio of the air discharged through the first discharge part 113 to the entire air discharged through the first discharge part 113 and the second discharge part 115 is increased.
- the mininum distances between the upstream end and the downstream end of the first discharge part 113, and the outer surface of the blower 120 are decreased, the ratio of the air discharged through the first discharge part 113 to the entire air discharged through the first discharge part 113 and the second discharge part 115 is decreased.
- the ratio of the air discharged through the second discharge part 115 to the air discharged through the first discharge part 113 and the second discharge part 115 is relatively increased.
- the single fan according to the embodiments discharges air in the two directions.
- the single fan simultaneously cools components disposed at various positions, thereby relatively reducing the number of parts used to cool the component, and even when the number of fans to be used is limited, the positions of parts can be varied.
