The heat exchanger comprises a first portion located on a first flow path formed to circulate air to the display module, a second portion to receive heat from the first portion, and located on a second flow path on which outside air is heat-exchanged with air, and a phase change material provided to circulate between the first and second portions, and provided to change a phase from a fluid to a gas. The case comprises a partition wall provided to isolate the first flow path and the second flow path from each other, and the first portion and the second portion are disposed obliquely. ## Claims ### Claim 1 An outdoor display apparatus comprising: a case comprising an inlet and an outlet; a display module disposed inside the case and comprising a display panel on which an image seen through at least a portion of the case is displayed; and a heat exchanger disposed to receive heat from the display module, wherein the heat exchanger comprises a first portion located on a first flow path formed to circulate air to the display module, at least a portion of the first portion being disposed in contact with the display module; a second portion provided to receive heat from the first portion, and located on a second flow path on which outside air is heat-exchanged with air; and a phase change material provided to circulate between the first portion and the second portion, and provided to change a phase from a fluid to a gas, wherein the case comprises a partition wall provided to isolate the first flow path and the second flow path from each other, and the first portion and the second portion are disposed obliquely. ### Claim 2 (depends on 1) The outdoor display apparatus of claim 1, wherein the heat exchanger comprises a head portion provided to receive heat from the display module and provided to accommodate the phase change material therein; a tube portion connected to the head portion to circulate the phase change material; and a heat exchange fin portion provided to increase a heat transfer of the tube portion. ### Claim 3 (depends on 2) The outdoor display apparatus of claim 2, wherein the first portion and the second portion are provided to be connected via the tube portion so as to communicate with each other. ### Claim 4 (depends on 1) The outdoor display apparatus of claim 1, wherein the partition wall is provided to isolate at least a portion of the first portion and the second portion. ### Claim 5 (depends on 1) The outdoor display apparatus of claim 1, wherein the first portion is positioned lower than the second portion. ### Claim 6 (depends on 2) The outdoor display apparatus of claim 2, wherein the heat exchanger comprises a partition wall mounting portion formed on at least a portion of the heat exchange fin portion. ### Claim 7 (depends on 1) The outdoor display apparatus of claim 1, wherein the heat exchanger comprises any one of a plurality of cooling fins or heat sinks or heat pipes. ### Claim 8 (depends on 1) The outdoor display apparatus of claim 1, wherein the first flow path is formed in closed space and further comprises a first fan configured to circulate air. ### Claim 9 (depends on 1) The outdoor display apparatus of claim 1, wherein the second flow path further comprises a second fan provided to allow air, which is sucked through the inlet, to be heat-exchanged through the second portion and to be discharged through the outlet. ### Claim 10 (depends on 2) The outdoor display apparatus of claim 2, wherein the heat exchange fin portion comprises any one of a stack fin or a folded fin. ### Claim 11 (depends on 1) The outdoor display apparatus of claim 1, wherein the heat exchanger comprises at least one of copper, stainless steel, aluminum, and plastic.
