Abstract

An outdoor display apparatus more particularly, to an outdoor display apparatus having a cooling structure. An outdoor display apparatus comprising: a case provided with an inlet and an outlet; a display module disposed inside of the case and provided with a display panel on which an image is displayed; and a heat exchanger configured to perform a heat-exchange by receiving heat from the display module; wherein the heat exchanger comprises a first cooling flow path configured to circulate air around the display module in a first direction; and a second cooling flow path configured to allow air to be introduced from the outside, to perform a heat-exchange with the air in the first cooling flow path, and to be discharged in a second direction.

First claim

What is claimed is:

1 . An outdoor display apparatus to display an image, comprising:
a case; a display module disposed inside of the case to display the image; and a heat exchanger configured to exchange heat generated from the display module, the heat exchanger comprising:
a first cooling flow path configured to circulate air around the display module in a first direction, and to exchange the heat generated from the display module with the circulated air through the first cooling flow path; and
a second cooling flow path configured to introduce air from an outside, to exchange the heat with the circulated air in the first cooling flow path, and discharge the introduced air in a second direction.

2 . The outdoor display apparatus of claim 1 , wherein
the first cooling flow path comprises a plurality of first flow paths formed by a part of a plurality of cooling channels, and the second cooling flow path comprises a plurality of second flow paths formed by a remainder of the plurality of cooling channels, wherein the air in the first flow path and the air in the second flow path are counter-flowed.

3 . The outdoor display apparatus of claim 2 , wherein
the case is provided with an inlet and an outlet; and the second flow path is configured to introduce the air via the inlet and discharge the air via the outlet.

4 . The outdoor display apparatus of claim 2 , wherein
the plurality of cooling channels are arranged to be alternately stacked.

5 . The outdoor display apparatus of claim 2 , wherein
the plurality of cooling channels comprises a flow path forming member configured to form any one of the first flow path and the second flow path between the plurality of cooling channels.

6 . The outdoor display apparatus of claim 4 , wherein
at least one part of the first flow path is formed inside of a cooling channel among the plurality of cooling channels, and the other part of the first flow path is formed outside of the cooling channel.

7 . The outdoor display apparatus of claim 4 , wherein
at least one part of the second flow path is formed inside of a cooling channel among the plurality of cooling channels, and the other part of the second flow path is formed outside of the cooling channel.

8 . The outdoor display apparatus of claim 1 , wherein
the case comprises a partition disposed between the first cooling flow path and the second cooling flow path.

9 . The outdoor display apparatus of claim 1 , wherein
the first cooling flow path is formed as a closed space.

10 . The outdoor display apparatus of claim 1 , wherein
the first cooling flow path comprises a first blowing device provided inside of the case to circulate air around the display module.

11 . The outdoor display apparatus of claim 1 , wherein
the case is provided with an inlet and an outlet; and the second cooling flow path comprises a second blowing device provided inside of the case to introduce air via the inlet to pass through at least one part of the heat exchanger and to be discharged via the outlet.

12 . The outdoor display apparatus of claim 1 further comprising:
at least one control unit configured to control an operation of the display module, wherein the control unit is disposed on the first cooling flow path.

13 . The outdoor display apparatus of claim 1 , wherein
the plurality of cooling channels comprises an air inlet and an air outlet to form the plurality of the first flow paths and the plurality of the second flow paths.

14 . The outdoor display apparatus of claim 13 , further comprising:
a flow path controller configured to control a flow of air in the first cooling flow path, wherein the flow path controller is disposed on the air outlet of a cooling channel among the plurality of cooling channels forming the first flow path among the plurality of cooling channels.

15 . The outdoor display apparatus of claim 13 , wherein
the case is provided with an inlet and an outlet; and the air inlet of a cooling channel forming the second flow path, among the plurality of cooling channels, is connected to the inlet, and the air outlet of the cooling channel forming the second flow path, among the plurality of cooling channels, is connected the outlet.

16 . The outdoor display apparatus of claim 13 , wherein
the air inlet comprises an extension extended by processing an end portion of the cooling channel.

17 . The outdoor display apparatus of claim 1 , further comprising:
the case is provided with an inlet and an outlet; and a temperature sensor disposed in the inlet.

18 . An outdoor display apparatus to display an image, comprising:
a case provided with an inlet and an outlet, wherein air is to be introduced via the inlet and discharged via the outlet; a display module to be disposed in the case and configured to display the image ; and a heat exchanger configured to exchange heat generated from the display module, the heat exchanger comprising:
a first cooling flow path disposed inside of the case and provided with a plurality of first flow paths configured to circulate air around the display module by a part of a plurality of cooling channels; and
a second cooling flow path provided with a second flow path formed by a remainder of the plurality of cooling channels and configured to allow the introduced air to flow in a direction opposite to a direction of the air circulated in the first flow path.

19 . The outdoor display apparatus of claim 18 , wherein
the first cooling flow path is disposed to exchange the heat from the display module and formed as a closed space so that the air is circulated around the display module.

20 . The outdoor display apparatus of claim 18 , wherein
the second cooling flow path is formed to allow the air to be introduced via the inlet and the introduced air to be discharged via the outlet.
