Abstract
A fluid-to-fluid heat exchanger comprising a body having channels side-to-side and extending end-to-end, said channels being capable of directing fluids in alternate and opposite (counter-flow) directions in the body, the body being crimped adjacent to said ends so that the fluid is fully enclosed in said body. Fluid entrance and exit openings in the body so that the alternate channels within the body can enable the fluid to achieve the desired conclusion of the heat exchanger, and manifolds secured to said heat exchanger so that they communicate with alternate channels within the heat exchanger, and some channels are not of the same cross sectional size so that some channels can move more fluid in a given time and are smaller than other channels.
Claims7
A fluid-to-fluid counter-flow heat exchanger comprising an extruded body having outer walls and multiple micro-channels side-to-side and extending between two opposite ends of said body, said micro-channels being capable of directing a first and a second fluid in alternate and opposite directions in said body, both of said body ends being crimped so that said first and second fluids are fully enclosed in said body, and said body having multiple entrance and exit openings in said body outer walls for said first and second fluids so that a first set of alternate micro-channels within the body receives said first fluid and a second set of alternate said micro-channels receives said second fluid, whereby said heat exchanger provides heat exchange between said first and second fluids.
