A heat exchanger for abating compounds produced in semiconductor processes is presented. When hot effluent flows into the heat exchanger, a coolant can be flowed to walls of a fluid heat exchanging surface within the heat exchanger. The heat exchanging surface can include a plurality of channel regions which creates a multi stage cross flow path for the hot effluent to flow down the heat exchanger. This flow path forces the hot effluent to hit the cold walls of the fluid heat exchanging surface, significantly cooling the effluent and preventing it from flowing directly into the vacuum pumps and causing heat damage. The heat exchanger can be created by sequentially depositing layers of thermally conductive material on surfaces using 3-D printing, creating a much smaller footprint and reducing costs.

An air coil unit of a heat exchanger includes tubes organized into separate circuits of serially connected tubes. The tubes of a given circuit are arranged in serially connected circuit portions, where the tubes of each circuit portion are arranged in rows. The circuits are arranged in a parallel flow-cross flow (PFCrF) configuration where the circuit crosses to adjacent rows between circuit portions to compensate for non-uniform air flow across the tubes. In the PFCrF circuit configuration, each circuit of the heat exchanger shares the non-uniformity of air flow, and mitigates the mal fluid distribution inside the tubes due to the non-uniform air flow across tubes.
