Abstract: A water block for cooling a heat-generating component has a body defining an internal fluid conduit for circulating fluid within the water block. The body defines a fluid inlet and a fluid outlet for feeding fluid into and discharging fluid from the internal fluid conduit respectively. The body includes: an external thermal transfer surface configured to be in contact with the heat-generating component; an opposite external surface on an opposite side of the body from the external thermal transfer surface; and at least one hollow fin extending from the opposite external surface, the at least one hollow fin defining at least one external fin passage, each of the at least one hollow fin defining an internal fin recess that forms part of the internal fluid conduit of the water block.

Abstract: Cooling arrangement and method for cooling of a heat source. The cooling arrangement includes a closed loop, a semi-open loop and at least one fan. The closed loop includes a primary side of a liquid-to-liquid heat exchanger receiving a first cooling fluid heated by the heat source, a first air-to-liquid heat exchanger downstream the primary side, and a first pump returning the first cooling fluid to the heat source. The semi-open loop includes a tank storing a second cooling fluid, a second pump drawing the second cooling fluid from the tank, a secondary side of the liquid-to-liquid heat exchanger receiving the second cooling fluid from the second pump, an evaporating pad downstream said secondary side, and an inlet fluidly connected to a source of the second cooling fluid. The at least one fan causes an air flow through the evaporating pad and through the first air-to-liquid heat exchanger.

Abstract: A heat exchanger assembly includes: a frame; a heat exchanger panel mounted to the frame and configured to exchange heat with air flowing therethrough, the heat exchanger panel being disposed at an inclined orientation; a fan assembly disposed vertically above the heat exchanger panel; and a sound dampening device disposed within an interior space of the heat exchanger assembly such that air is pulled into the interior space through the heat exchanger panel and then flows through the sound dampening device before being discharged from the heat exchanger assembly via the fan assembly. The sound dampening device includes baffle members having sound absorbing material and spaced apart from one another for allowing air flow therebetween. Each baffle member extends at an angle relative to a plane extending through the upper and lower ends of the heat exchanger panel so as to direct air flow upwardly toward the fan assembly.
