Abstract
A cooler and a display device including the cooler. The cooler includes: a housing; an air blowing unit disposed inside the housing and sucking external air and blowing the external air in the housing, wherein the air blowing unit includes a plurality of groups each including two air blowers; a guide vane disposed above the air blowing unit and to guide air flowed out from the air blowing unit to flow in different directions; and a plurality of auxiliary guide vanes disposed between the air blowing unit and the guide vane, and each disposed in each of the groups each including two air blowers, so as to guide air flowing below the air blowing unit to flow toward the guide vane.
Claims30
A cooler comprising:
- a housing;
- an air blowing unit disposed inside the housing and sucking external air and blowing the external air in the housing, wherein the air blowing unit comprises a plurality of groups each including two air blowers;
- a guide vane disposed above the air blowing unit and guiding air that flows out from the air blowing unit to flow in different directions;
- and
- a plurality of auxiliary guide vanes disposed between the air blowing unit and the guide vane, each of the auxiliary guide vane being disposed in each of the groups each including two air blowers, so as to guide air flowing below the air blowing unit to flow toward the guide vane.
A display device comprising:
- a display unit to display an image;
- and
- a cooler to cool heat generated from the display unit,
- wherein the cooler comprises:
- a housing;
- an air blowing unit disposed inside the housing and sucking external air and blowing the external air in the housing, wherein the air blowing unit comprises a plurality of groups each including two air blowers;
- a guide vane disposed above the air blowing unit and guiding air that flows out from the air blowing unit to flow in different directions;
- and
- a plurality of auxiliary guide vanes disposed between the air blowing unit and the guide vane, each of the auxiliary guide vanes being disposed in each of the groups each including two air blowers, so as to guide air flowing below the air blowing unit to flow toward the guide vane.
The display device of claim of 11, further comprising an interference preventing portion that is disposed between the plurality of groups of the air blowing unit, prevents interference of air flows between the groups of the air blowing unit, and guides air to flow toward the guide vane.
The display device of claim of 14, further comprising an auxiliary interference preventing portion disposed between the air blowers forming each group of the air blowing unit so as to prevent interference of air flows between the air blowers and to guide the air to flow toward the guide vane.
The display device of claim of 15, further comprising a plurality of vortex removing portions disposed at both sides of a portion below each of the air blowers so as to remove a vortex generated when the air blower revolves.
The display device of claim of 16, wherein the vortex removing portion comprises a plurality of first vortex removing portions that are respectively connected to the interference preventing portion and the auxiliary interference preventing portion and each have a reversed V-shaped cross-section, and a plurality of second vortex removing portions that are respectively formed to be connected to side plates of the housing so as to be inclined at a predetermined angle.
The display device of claim of 11, further comprising a side auxiliary guide vane that is disposed to be parallel to the guide vane and guides air that flows out from the air blowers to flow toward the guide vane.
The display device of claim of 11, wherein a normal central axis perpendicular with respect to a revolution axis of the air blower is spaced apart from a normal guide vane axis that corresponds to the guide vane and that is perpendicular with respect to the revolution axis.
The display device of claim of 19, wherein a central normal with respect to a revolution axis of the air blower is biased toward the display unit.
The display device of claim of 11, further comprising a plurality of suction inducing units each guiding external air of the housing to flow toward the air blower.
A cooler comprising:
- a housing extending lengthwise along an axis and having an air chamber traversing along the axis and extending to a top opening;
- an air blowing unit disposed in the housing and below the air chamber and including a plurality of air blowers disposed along the axis of the housing to draw external air inside the housing and to flow air upward toward the air chamber;
- and
- a guide vane disposed in the air chamber and defining a front cooler air channel extending to the top opening of the housing and a rear cooler air channel extending to the top opening of the housing.
A display device comprising:
- a display housing including a top and a bottom having an air passage and a front portion extending from the bottom to the top and a rear portion extending from the bottom to the top and having a front housing air path inside the front portion extending from the air passage to the top of the housing and a rear housing air path inside the rear portion extending from the air passage to the top of the housing;
- a display unit disposed in the housing and between the front housing air path and the rear housing air path;
- a cooler comprising:
- a cooler housing including an open top disposed against the air passage of the bottom of the display housing and including an air chamber inside the cooler housing extending to the open top to direct air toward the air passage of the display housing;
- an air blowing unit disposed in the cooler housing and below the air chamber and including at least one blower to draw external air inside the cooler housing and to flow the drawn air upward toward the air chamber;
- and
- a guide vane disposed in the chamber and defining a front cooler air channel in communication with the front housing air path and defining a rear cooler air channel in communication with the rear housing air path,
- wherein air drawn into the cooler housing by the blower flows from the front and rear cooler air channels into the front and rear housing paths, respectively, via the guide vane and the display unit is cooled as air flows through the front housing air path and the rear housing air path.
A method of cooling a display unit included in a display device using a cooling unit, comprising:
- drawing external air into the cooling unit;
- capturing the drawn air into an air chamber of the cooling unit;
- dividing the captured air in the air chamber into a front air flow and a rear air flow;
- flowing the front air flow across a front side of the display unit;
- and
- flowing the rear air flow across a rear side of the display unit.
