A baffle for engine fluid cooling includes a fluid guide having a pair of side walls, a bottom wall, and a coolant fluid inlet. A channel receives a pair of heat exchangers such that one may be positioned proximate to or above a part of the bottom wall and the other may be positioned proximate to or above another part of the bottom wall. Some coolant entering the guide flows into the first heat exchanger and some coolant is passed under the first heat exchanger and subsequently into the second heat exchanger.

A heat exchanger in which inner wall surfaces of refrigerant passages through which a first refrigerant and a second refrigerant flow are constituted by a different metal and in which a heat exchange performance is improved. Second-refrigerant heat-transfer tubes that are formed with a metal different from a heat transfer block are each inserted through a corresponding second-refrigerant heat-transfer-tube insertion hole. The second-refrigerant heat-transfer tubes are formed with a metal with a different material from that of the heat transfer block.

A surface cooler comprises a plate-like layer and a plurality of spaced-apart fins extending substantially perpendicular from an uppermost layer of the plate-like layer. The plurality of fins defining a plurality of air flow paths. The plurality of spaced-apart fins are configured to augment heat transfer of the surface cooler by increasing the turbulence levels of a fluid flowing through the airflow paths by promoting increased mixing with a resulting increase in the heat transfer coefficient of the surface cooler. A method of forming the surface cooler and an engine including the surface cooler.

A cooling apparatus for removing heat having a low profile unitary member. The low profile unitary member has an evaporator portion and a condenser portion. The evaporator portion is thermally exposed to a heat generating component. The condenser portion is disposed at an elevated angle with respect to the evaporator portion. A plurality of microtubes are disposed within the first low profile extrusion. The plurality of microtubes have a heat transfer fluid contained therein. A second plurality of low profile extrusion members are mounted as fins on the evaporator section of the low profile unitary member. Heat is transferred from the heat generating component to the heat transfer fluid contained with the microtubes located within the evaporator portion. The heat transfer fluid to which the heat was transferred migrates to the condenser portion of the low profile unitary member by way of the microtubes. The heat transfer fluid is cooled in the condenser portion of the low profile unitary member. Cooling of the heat transfer fluid within the condenser section is enhanced by the second plurality of low profile extrusion members. The heat transfer fluid is returned to the evaporator section after cooling.

A reliable, leak-tolerant liquid cooling system with a backup air-cooling system for computers is provided. The system may use a vacuum pump and a liquid pump and/or an air compressor in combination to provide negative fluid pressure so that liquid does not leak out of the system near electrical components. Alternatively, the system can use a single vacuum pump and a valve assembly to circulate coolant. The system distributes flow and pressure with a series of pressure regulating valves so that an array of computers can be serviced by a single cooling system. The system provides both air and liquid cooling so that if the liquid cooling system does not provide adequate cooling, the air cooling system will be automatically activated. The heat may be removed from the building efficiently with a cooling tower.
