Abstract: The present disclosure relates to a cooler and to a display device having the same, where a heat-exchanger of the cooler is arranged on a side surface of a display unit in order to simplify the structure and to make a slimmer display device. The cooler includes a closed air circulation pathway circulating between the front, rear and sides of the display unit; an open air flow pathway that flows in the length direction of the side of the display unit; and a cooling module that is installed on the side of the display along the length direction of the display, and that includes the heat-exchanger, where the closed air circulation path and the open air flow part are adjacent, thereby causing heat-exchange.

Abstract: A heat exchanger is provided. The heat exchanger includes a plurality of aluminum tubes formed of aluminum, each of the aluminum tubes including a plurality of grooves that are formed on an inner circumferential surface of each of the aluminum tubes and that extend along a longitudinal direction of the aluminum tubes; and a plurality of heat transfer fins coupled to the aluminum tubes. The heat exchanger may contribute to the reduction of the manufacturing cost, may provide high heat transfer performance and may prevent a coolant leak.

Abstract: A heat exchanger is provided. The heat exchanger includes at least one fin provided with a plurality of slits and a plurality of refrigerant tubes penetrating the fin. The refrigerant tubes include at least one front line tube and at least one rear line tube having a different diameter from the front line tube with reference to a fluid flow direction. The slits include at least one front line slit and at least one rear line slit having a difference width with reference to the fluid flow direction.

Abstract: A heat exchanger including a plurality of first refrigerant tubes, and a plurality of second refrigerant tubes separated from the plurality of first refrigerant tubes in an air flow direction. Further, a diameter of a respective refrigerant tube of the plurality of first refrigerant tubes is smaller than a diameter of a respective refrigerant tube of the plurality of second refrigerant tubes.
