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 heat exchanging surface within the heat exchanger. The heat exchanging surface can be a curved shaped 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 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 foot print and reducing costs. 1. A heat exchanger configured to exchange heat with a flowing fluid , comprising:a first mounting flange having a central opening that extends through a connection surface of the first mounting flange, wherein the connection surface is parallel to a first plane;a second mounting flange having a central opening that extends through a connection surface of the second mounting flange, wherein the second mounting flange is disposed a distance in a first direction from the first mounting flange;an outer wall that is configured to enclose an internal region of the heat exchanger, wherein the outer wall and internal region are disposed between the first mounting flange and the second mounting flange;an inner wall that is disposed within the internal region, wherein the inner wall is positioned to isolate a heat exchanging region of the internal region from an outer region of the internal region, the outer region defined by a space formed between the inner wall and the outer wall;a heat exchanging fluid inlet port and a heat exchanging fluid outlet port, wherein the heat exchanging fluid inlet port and ...
