Abstract: A valve in the flow aperture of a removable coolant reservoir enables coolant to flow between the reservoir and a coolant system while preventing the coolant in the reservoir from spilling when the reservoir is disconnected from the coolant system. A filling tube with a lower end and an air escape passage discourage users from overfilling the reservoir. Once the coolant level reaches the lower end, fluid accumulates in the filling tube, thereby indicating to the user that the reservoir is full. The air escape passage then gradually allows displaced air to escape and coolant in the filling tube to enter the reservoir. An overflow port and tube attached to the filling tube divert excess coolant away from the reservoir. A bleed tube, a bleed port, and a barrier in the reservoir remove bubbles from the coolant system and prevent the removed bubbles from reentering the coolant system.

Abstract: An actively cooled daughterboard system. One more daughterboards are mounted in parallel rows on a motherboard. Each daughterboard is oriented substantially perpendicular to the motherboard, but may optionally be mounted at an oblique angle relative to the motherboard. Each daughterboard has a low-profile thermally-efficient heatsink mounted thereon. A fan shroud partially covers the daughterboards, but has openings in its sides for directing air flow through plural fins on the heatsinks and through a fan mounted to the top of the fan shroud. The inventive daughterboard system enables multiple high heat dissipating daughterboards to be placed closer together than the daughterboard systems of the prior art while still keeping the daughterboards adequately cooled. Moreover, because only a single fan is used to cool all of the daughterboards under the shroud, noise and expense are reduced relative to prior art systems that employed one or more fans per daughterboard.

Abstract: An engine cooling system for an automotive vehicle including a liquid coolant deaeration and overflow bottle having plural cells constituting a degassing chamber assembly with the first cell having only an upper fluid inlet for initially receiving liquid coolant from the engine cooling system and a lower flow-through window which leads into an adjacent cell for receiving coolant from the first cell. The other cells are likewise connected together in series and the final cell has an outlet connected back into the engine cooling system. Coolant in the cells of the degassing chamber assembly creates a liquid trap arrangement to prevent any substantial back flow of accumulated air from the deaeration chamber assembly back into the engine's cooling system when engine operation is terminated. Most importantly, this prevents any formation of air bubbles in the heater core circuit which may restrict coolant flow and seriously degrade heater effectiveness, particularly at idle and low engine speed operation.
