A display unit and a vending machine having the same. The display unit includes a display panel to display an image, a circuit board to control the display panel, a board bracket installed at a rear of the display panel and formed with a receiving section to receive the circuit board, and a plurality of inlet holes and a plurality of outlet holes formed in opposite surfaces of the board bracket to allow external air to flow through the receiving section. The air travels through the inlet and outlet holes and passes through the receiving section in one direction to cool the display panel and the circuit board. Thus, the display unit is prevented from malfunctioning and the display panel is prevented from being degraded by heat even if tempered glass is installed at a front of the display panel.

A vending machine comprising: a housing;a display unit installed in the housing to display an image, wherein the display unit comprises:a display panel for displaying the image;a circuit board for controlling the display panel;a board bracket installed at a rear of the display panel and formed with a receiving section to receive the circuit board; anda plurality of inlet holes and outlet holes formed in opposite surfaces of the board bracket to allow external air to flow through the receiving section,wherein perforation holes are formed in a front surface of the board bracket adjacent to a rear surface of the display panel to allow heat generated from the display panel to be transferred to the receiving section of the board bracket. 11. The vending machine of claim 10, further comprising a plurality of blowing fans installed in the inlet and outlet holes to guide external air into and out of the receiving section, respectively. 12. The vending machine of claim 11, wherein the opposite surfaces of the board bracket are provided with the inlet holes and the outlet holes arranged in a row, respectively. 13. The vending machine of claim 11, wherein the blowing fans include axial-flow fans and shafts of the axial-flow fans are arranged in parallel to a surface of the circuit board. 14. The vending machine of claim 10, wherein the circuit board includes a power board installed at an upstream side of the air to convert input power into operating power for the display unit, and a main board installed at a downstream side of the air to control operation of the display unit. 15. The vending machine of claim 10, wherein the circuit board is spaced apart from a rear surface of the display panel to allow the air to flow between the circuit board and the display panel. 16. The vending machine of claim 10, wherein the display panel includes a liquid crystal panel. 17. The vending machine of claim 10, further comprising tempered glass installed at a front of the display panel to prevent the display panel from being broken. 18. The vending machine of claim 10, further comprising a cover that covers an open rear side of the board bracket. 19. The vending machine of claim 10, wherein the housing formed with a suction port for sucking air from an outside and a discharge port for discharging the air after the air has passed through the display unit. 20. The vending machine of claim 19, wherein the inlet holes formed in a lower surface of the board bracket, the outlet holes are formed in an upper surface of the board bracket, and the suction port is formed at a lower portion of the housing, and the discharge port is formed at an upper portion of the housing, so that the air is guided to flow upward in the housing while passing through the display unit. 21. The vending machine of claim 20, wherein the suction port is formed in at least one of a lower surface and a side surface of the housing, and the discharge port is formed at an upper surface of the housing. 22. A method of discharging heat from a display unit usable with a vending machine, the method comprising: installing a board bracket on a display panel, the board bracket having a receiving section, a circuit board installed on the board bracket through the receiving section, and a plurality of inlet holes and outlet holes formed in opposite surfaces of the board bracket to allow air to flow within the display unit,wherein perforation holes are formed in a front surface of the board bracket adjacent to a rear surface of the display panel to allow heat generated from the display panel to be transferred to the receiving section of the board bracket. 23. A display unit usable with a vending machine, comprising: a display panel to display an image thereon, anda board bracket installed on the display panel having a circuit board installed thereon to control the display panel, and having an air passage between surfaces of the board bracket and surfaces of the circuit board,wherein perforation holes are formed in a front surface of the board bracket adjacent to a rear surface of the display panel to allow heat generated from the display panel to be transferred to a receiving section of the board bracket. 24.
