Abstract: An electronic device having a base includes a circuit board, a electronic element, and a heat sink. The electronic element is mounted on the circuit board. The heat sink attaches to the electronic element. The heat sink includes an attaching wall and at least one side wall. The attaching wall attaches to the electronic element and having two opposite ends. At least one side wall connects to the ends of the attaching wall. The side wall and the attaching wall form a tube with an intake opening and an outtake opening. The intake opening faces the base and the outtake opening is opposite to the intake opening.

Abstract: A heat dissipation structure for a liquid crystal television is disclosed. The liquid crystal television includes a front plate and a rear plate. The front plate has a screen and a metal backboard. The heat dissipation structure includes a printed circuit board (PCB) mounted to the metal backboard; a television integrated circuit (IC) chip for controlling operations of the liquid crystal television being attached on the PCB; and one or more heat dissipating posts provided between the PCB and the metal backboard. The heat generated by the television IC chip is dispersed to the metal backboard via the heat dissipating post or posts.
