Abstract
A heat exchanger useful for mounting to an electronic component housing or other system requiring heat exchange. The heat exchanger has a manifold having a cross-sectional configured for providing an unequal coolant flow to an array of cooling channels fed by the manifold, thereby providing for preferential amounts of heat exchange over a given heat exchange surface of the heat exchanger. A safety channel may surround the channels carrying the coolant to prevent potential leakage outside of the heat exchanger.
Claims18
A heat exchanger comprising:
- a body having a plurality of cooling channels defined therein, and a fluid supply manifold located at a first end of the cooling channels, the fluid supply manifold being in parallel fluid flow communication with the cooling channels for feeding coolant thereto, the fluid supply manifold having a cross-sectional area which varies over its length and thereby configured for providing greater coolant flow to cooling channels fed by portions of the fluid supply manifold having a greater cross-sectional area than remaining portions of the fluid supply manifold.
A heat exchanger comprising a first plate having a first surface, and a second plate, the second plate abutting the first surface of the first plate in sealing engagement, the first plate and the second plate including therebetween:
- a plurality of cooling channels, a supply channel being in fluid-flow communication with the cooling channels for supplying coolant thereto, a discharge channel being in fluid-flow communication with the cooling channels for discharging fluid therefrom, and a safety channel circumscribing the cooling channels, the supply channel and the discharge channel for collecting any coolant leakage therefrom, the first plate having a second surface opposite the first surface, the first surface cooling the second surface when coolant flows through the cooling channels.
A heat exchanger comprising:
- a first plate having two protrusions on opposite sides thereof, the first plate having an undersurface having a plurality of cooling channels defined therein in a side-by-side parallel configuration, a fluid supply channel located at a first end of the cooling channels and disposed transversally with respect to the cooling channels, the fluid supply channel being in fluid flow communication with the cooling channels for feeding coolant thereto, a fluid removal channel located at a second end, opposite the first end, of the cooling channels and disposed transversally with respect to the cooling channels, the fluid removal channel being in fluid flow communication with the cooling channels for removing fluid therefrom, a fluid connection inlet for connection with a coolant supply source for providing coolant to the heat exchanger and which is in fluid flow communication with the fluid supply channel, the fluid connection inlet being provided at a first one of the two protrusions, a fluid connection outlet for connection with a coolant exhaust so as to discharge coolant from the heat exchanger and which is in fluid flow communication with the coolant removal fluid channel, the fluid connection outlet being provided at a second one of the two protrusions,
- a second plate coupled with the undersurface of the middle plate so as to seal the cooling channels, the fluid supply channel, the fluid removal channel, the fluid connection inlet and fluid connection outlet;
- wherein the first plate includes a top surface in heat exchange relationship with components to be cooled, the coolant flowing through the cooling channels on the undersurface of the first plate removing heat from the top surface of the first plate.
