Abstract: A liquid cooling device includes a base (1), a passive impeller (3) and a cold plate (4). The base (1) includes a division plate (11), a chamber (12) and a flow guiding pole (13). The division plate (11) divides the chamber (12) into a catchment portion and a heat exchanging portion (17). The flow guiding pole (13) communicates with both the catchment portion (16) and the heat exchanging portion (17). The passive impeller (3) is received in the chamber (12) and radially driven to rotate by the working fluid. The cold plate (4) is arranged correspondingly to the heat exchanging portion (17) and fastened to the base (1).

Abstract: A water/air dual cooling method CPU cooling arrangement includes a metal water accumulator attached to the CPU to be cooled, a heat exchanger, a pump adapted to pump water through the metal water accumulator and the heat exchanger, keeping cooling water continuously circulated through the metal water accumulator to carry heat away from the CPU, a heat sink attached to the metal water accumulator, and a fan mounted on the heat sink and adapted to cause currents of air toward the heat sink.

Abstract: An electronic device cooling arrangement, which includes a flat, rectangular metal water container attached to an electronic device, for example, a CPU for carrying heat away from the CPU, the metal water container having a thinner middle portion for causing a venturi effect upon flowing of water through the metal water container, a first plug installed in one thicker lateral portion of the metal water container for guiding a flow of cooling water from an external water source into the metal water container, and a second plug installed in an opposite thicker lateral portion of the metal water container remote from the first plug for guiding the intake flow of cooling water out of the metal water container for enabling heat to be carried away from the CPU with the output flow of cooling water.
