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.

The shower system has a heat exchanger located in compartment vertically adjacent to the wall of the shower space and closed off by an openable or removable panel. The heat exchanger comprising a helically winding heat exchange conduit with successive windings around a vertical axis in said compartment above the floor of the shower space. A pump coupled to the shower drain pumps warm water to a warm water feed of the heat exchanger, from where it is sprayed on a top winding of the heat exchange conduit. Tap water is fed to the shower head successively via the heat exchange conduit and a heater and/or a mixing element for mixing water from the heat exchanger with water from a supply input for external hot water.

An exhaust gas heat exchanger having stacked flat tubes includes a stacked tube body configured by stacking a plurality of flat tubes in multiple tiers with spaces therebetween and arranged inside a case; exhaust gas flows in from a first end part of the stacked tube body in a tube axis direction, circulates through each flat tube, and flows out from the a second end part; and cooling water from the case is supplied to the first end part to circulate along an exterior surface side of each flat tube. The cooling water is introduced into the tubes from two locations of the case and in mutually opposite directions which are parallel to flat surfaces of the tubes and vertical in the axis direction of the flat tubes.

A heat exchange system for a gas turbine engine includes a first heat exchanger that defines a first heat source flowpath, a second heat exchanger that defines a second heat source flowpath, and a coolant fluid circuit. The coolant fluid circuit defines a first coolant flowpath that extends through the first heat exchanger and is in thermal communication with the first heat source flowpath, and a second coolant flowpath that extends through the second heat exchanger and is in thermal communication with the second heat source flowpath. The first coolant flowpath and the second coolant flowpath are arranged in a parallel flow configuration.
