Claim:
A cooling unit to cool a display apparatus comprising a heat generating unit to generate heat and a casing having an inner space to accommodate the heat generating unit, the cooling unit comprising: a cooling fan to generate air flow; a duct which is coupled with the casing and forms a cooling path to cool the heat generating unit such that the air flow generated by the cooling fan does not enter the inner space; an inlet portion which is provided to one side of the casing to communicate with the duct; an inlet grill which is provided in the inlet portion to guide air to be inhaled in a direction inclined to a rear surface of the casing; an outlet portion which is provided to an other side of the casing to communicate with the duct, being spaced from the inlet portion; an outlet grill which is provided in the outlet portion to guide air to be exhaled in a direction inclined to the rear surface of the casing; and a heat transfer unit which is coupled with the heat generating unit and the duct and transfers the heat from the heat generating unit to the duct, wherein the exhaled direction provided by the outlet grill is different from the air-inhaling direction provided by the inlet grill.
