<p>An electronic apparatus, such as personal computers of desktop type and notebook type, as well as a server, etc., having a cooling system being high in cooling efficiency, wherein a CPU (200) in need of cooling is installed within a housing (100), and the liquid cooling system for cooling the CPU, comprises: a heat-receiving (cooling) jacket (50); a radiator (60); and a circulation pump (70), wherein the heat-receiving (cooling) jacket (50), for transmitting heat generated from a heat-generation element, i. e., the CPU, into a liquid coolant flowing within an inside thereof, has a heat diffusion plate (90) attached on the lower surface thereof. This heat diffusion plate encloses an operating fluid (94), such as water, within a space, which is hermetically sealed and formed within an inside thereof, and also has heater elements (95), being provided in contact with a portion the operating fluid. To those heater elements (95) are supplied a pulse-like electric power. With this, a portion of the operating fluid repeats forming/extinguishing, to give vibration to the operating fluid, thereby diffusing the heat over the entire of the diffusion plate, thereafter the heat is transmitted to the heat-receiving (cooling) jacket. Or, alternatively, it may be connected with a heat radiation fin (300).</p> |
