Embodiments described herein relate to a heat exchanger for abating compounds produced in semiconductor processes. 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. Embodiments described herein also relate to methods of forming a heat exchanger. 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.

A heat exchanger can include a plurality of flat tubes each having a heat exchange channel for a flow of a heat exchange medium, and a first collector pipe and a second collector pipe connected to distal sections of the plurality of flat tubes and disposed side by side. Chambers of the first collector pipe and the second collector pipe can be in communication with the heat exchange channels of the flat tubes. The flat tube includes a main body section, a distal section, and a torsion section connected therebetween. The main body section and the distal sections can be straight sections. The first collector pipe and the second collector pipe can be provided with mounting holes for the distal section being inserted into. A length direction of the mounting hole can be inclined to the axis of the first collector pipe or the axis of the second collector pipe.
