The present invention relates to a heat exchanger having a means for reducing thermal stress. An object of the present invention is to provide an integrated heat exchanger configured to cool two types of heat exchange media having different temperatures, the heat exchanger having a means for reducing thermal stress and having a flow distribution structure in a tank in order to effectively disperse thermal stress caused by a temperature difference.

A dew point corrosion resistant heat exchanging system having a plurality of hollow heat transferring tubes through which cooler ambient air or hot combustion product gases flow. The other of the air or gas flows across the outer surfaces of the tubes, and heat is transferred from the hot gases to the ambient air, thus heating the air. A portion of the tubes includes an inner liner forming an air pocket chamber between the liner and the outer wall of the tube. The air pocket chamber provides heat transfer advantages that maintain the tubes at a temperature above the dew point of the gases in the system, thus inhibiting corrosion of the tubes.

The present disclosure provides a drain assembly for an AC furnace coil unit. The drain assembly includes a drain pan defining one or more drain channels extending longitudinally therealong, and an arcuate heat shield detachably coupled to the drain pan. The arcuate heat shield extends along a length of the drain pan. The arcuate heat shield is configured to define a cavity between an inner surface thereof and the drain pan, and distribute airflow, incident on an outer surface thereof, along longitudinal sides of the drain pan.

A method of conditioning wastewater includes flowing wastewater into and through a first fluid tube and flowing a heat transfer fluid into and through a second fluid tube.

The one or more thermal energy transfer devices are configured to transfer the thermal energy throughout the one or more materials and at least partially between the heat input region and the cold sink interface region. The one or more materials are also configured to absorb and store excess thermal energy in response to a temperature excursion associated with a thermal transient event and to release the stored thermal energy after the thermal transient event.

A water block assembly comprising a water block unit and an insulating housing, and a method for insulating a water block unit are provided. The water block unit has an external thermal transfer surface configured to be in contact with a heat generating component to be cooled, and defines an internal fluid conduit for circulating fluid therein, a fluid inlet for feeding fluid into the internal fluid conduit, and a fluid outlet for discharging fluid from the internal fluid conduit. The insulating housing at least partly embeds the water block unit therein to limit heat transfer from the water block unit to a surrounding environment thereof, the insulating housing having an internal surface in contact with the water block unit.

A heat transfer fin includes a fin body having a plate shape, a plurality of through-holes famed through the fin body and spaced apart from each other in a first direction, in which a heat exchange pipe is inserted into the plurality of through-holes and heating water flows along an empty space in the heat exchange pipe, and two outer body portions protruding outward from at least partial areas of opposite ends of the fin body with respect to the first direction. Each of the outer body portions includes a contact portion that makes contact with a heat-insulating pipe with a heat-insulating side plate therebetween and that has a shape corresponding to at least a partial area of an outer surface of the heat-insulating pipe through which the heating water flows and a separated portion spaced apart from the heat-insulating side plate to form a gap.

A heat exchanger includes: a heat exchanger body which includes an adhesive lower damping material which is provided on a lower outer peripheral surface of a lower tubular member exposed from a lower buffer material provided in each of both end portions in both end portions of the lower tubular member constituting at least a lower header and is formed such that at least a portion of each of both end portions extends between the lower tubular member and the lower buffer material; and a casing which includes first and second abutment portions against which the lower buffer material abuts and a condensate water discharge unit which discharges condensate water to an outside.
