Panel type display device
A panel type display device for minimizing temperature increase in the interior of a case and a display panel. The display device includes a case, a display panel mounted in an interior of the case, at least one circuit board for controlling the display panel, a first cooling fluid path for cooling the display panel, and a second cooling fluid path for cooling the circuit board. In the display device, the first and second cooling fluid paths are separated from each other.
1. A panel display device comprising:
a case;
a display panel mounted in an interior of the case;
at least one circuit board which controls the display panel;
a first cooling fluid path which cools the display panel; and
a second cooling fluid path which cools the circuit board,
wherein the first and second cooling fluid paths are separated from each other, and
wherein the case includes a circuit board mounting part provided on a rear surface of the case and partitioned from a space in which the display panel is mounted such that the circuit board is received in the circuit board mounting part, the first cooling fluid path includes a space between a rear surface of the display panel and an inner surface of the case, and the second cooling fluid path includes an internal space of the circuit board mounting part.
2. The panel display device as claimed in claim 1 , wherein the case includes front and rear cases coupled to each other, and the rear case includes a circuit board mounting part provided on an outer surface of the rear case such that the circuit board is mounted in the circuit board mounting part.
3. The panel display device as claimed in claim 2 , wherein the circuit board mounting part has an open rear while being recessed from an outer surface of the rear case such that the circuit board is mounted in the circuit board mounting part, and a cover for covering the circuit board mounting part, on which a plurality of air flow holes are formed, is mounted on the circuit board mounting part.
4. The panel display device as claimed in claim 3 , wherein the first cooling fluid path includes a space between a rear surface of the display panel and an inner surface of the rear case, and the second cooling fluid path includes an internal space of the circuit board mounting part.
5. The panel display device as claimed in claim 2 , wherein the first cooling fluid path includes a space between a rear surface of the display panel and an inner surface of the rear case, and the second cooling fluid path includes an internal space of the circuit board mounting part.
6. The panel display device as claimed in claim 4 , wherein air inlets through which air flows in the first cooling fluid path are formed at a lower portion of the rear case, and air outlets through which air is exhausted from the first cooling fluid path are formed at an upper portion of the rear case.
7. The panel display device as claimed in claim 2 , wherein a cover for covering the circuit board mounting part, on which a plurality of air flow holes are formed, is mounted on an outer rear surface of the rear case, the first cooling fluid path includes a space between a rear surface of the display panel and an inner surface of the rear case, and the second cooling fluid path includes a space confined by the circuit board mounting part and the cover.
8. A panel display device comprising:
a case;
a partition plate for dividing an interior of the case into first and second cooling fluid paths;
a display panel mounted between the partition plate and a front surface of the case to be cooled by air flowing in the first cooling fluid path; and
at least one circuit board mounted between the partition plate and a rear surface of the case to be cooled by air flowing in the second cooling fluid path wherein at least one circuit board is mounted to a circuit board mounting part provided on a rear surface of the case,
wherein the partition plate divides the case into a first space in which the display panel is mounted and a separate second space in which the circuit board is mounted, and
wherein the first cooling path comprises the space between a rear surface of the display panel and an inner surface of the case and the second cooling path comprises the space in which the circuit board is mounted.
9. The panel display device as claimed in claim 8 , wherein air inlets and outlets are formed at lower and upper portions of the case, respectively, for allowing air to flow into the first cooling fluid path.
10. The panel display device as claimed in claim 8 , wherein a plurality of air flow holes through which air flows are formed on the rear surface of the case for allowing air to flow into the second cooling fluid path.
