Abstract: A fluid compensation apparatus is configured to provide replacement fluid to a fluid-based cooling loop, while removing dissolved gas or gas in gross bubbles from the cooling loop. Removal or reduction of gas from the cooling loop reduces or prevents pump vapor lock. The removed gas is retained within the fluid compensation apparatus. The fluid compensation apparatus is configured to prevent the trapped gas from being re-introduced to the fluid-based cooling loop, regardless of the orientation of the fluid compensation apparatus. Additionally, the fluid compensation apparatus is configured to remove gas from and add fluid to the cooling loop with limited or no pressure drop between the inlet port and the outlet port of the fluid compensation apparatus. As a result, the pump does not require additional power to compensate for such a pressure differential.

Abstract: A cooling system includes a cooling unit configured to fit within a single drive bay of a personal computer. The cooling unit includes a fluid-to-air heat exchanger, an air mover, a pump, fluid lines, and control circuitry. The cooling system also includes a cooling loop configured to be coupled to one or more heat generating devices. The cooling loop includes the pump and the fluid-to-air heat exchanger from the cooling unit, and at least one heat exchanger coupled together via flexible fluid lines. The heat exchanger is thermally coupled to the heat generating device. The cooling unit is configured to maintain noise below a specified acoustical specification. To meet this acoustical specification, the size, position, and type of the components within the cooling unit are specifically configured.
