A method of installing a segment of a recuperator within an exhaust duct of a gas turbine engine, including positioning the segment such that its exhaust inlet is in fluid flow communication with the turbine section and its exhaust outlet is adapted to deliver an exhaust flow to atmosphere, engaging its air inlet to a plenum in fluid flow communication with the compressor discharge, and engaging its air outlet to another plenum containing the combustor. One of engaging the air inlet and engaging the air outlet includes forming a rigid connection providing sealed fluid flow communication with the corresponding plenum, and the other of engaging the air inlet and engaging the air outlet includes forming a floating connection providing sealed fluid flow communication with the corresponding plenum. The floating connection allows relative movement of the segment within the exhaust duct.

Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes in which a refrigerant flows, a heatsink fin coupled to the plurality of refrigerant tubes to heat-exchange the refrigerant with a fluid, a header disposed on at least one side of the plurality of refrigerant tubes to define a flow space of the refrigerant and a guide device disposed in the header to partition the flow space, the guide device guiding the refrigerant from the header to the refrigerant tubes. The guide device includes a movable cover part.

A heat exchange device of a floating core type, having a special configuration which allows increasing its durability as it increases its thermal fatigue resistance. The device is characterized by a configuration having high thermal fatigue resistance due to the special configuration of the end where the floating side of the core is located since stagnation regions that are usually produced in the baffle of the floating end are eliminated by the combination of the shape of the shell and of a deflector. This configuration furthermore results in a low-cost exchanger.

A compliant heating system includes a dynamic component including a heat exchanger; a pressure vessel shell encompassing at least a portion of the heat exchanger; and a accessible and detachable compressive seal expansion that connects the dynamic component and the pressure vessel shell.

A plate heat exchanger includes a plate stack including a plurality of heat transfer plates stacked with each other. Each of the heat transfer plates includes a heat medium inflow hole serving as an inlet for a heat medium, a heat medium outflow hole serving as an outlet for the heat medium, a refrigerant inflow hole serving as an inlet for refrigerant, and a refrigerant outflow portion located below the refrigerant inflow hole and serving as an outlet for the refrigerant. The heat transfer plates define heat medium passages, through each of which the heat medium flowing from the heat medium inflow hole flows, and refrigerant passages, through each of which the refrigerant flowing from the refrigerant inflow hole flows downward, arranged alternately with one another. Each of the heat medium passages and the refrigerant passages is defined between adjacent ones of the heat transfer plates.

A compliant heating system includes a dynamic component including a heat exchanger; a pressure vessel shell encompassing at least a portion of the heat exchanger; and a compressive seal expansion that connects the dynamic component and the pressure vessel shell.

An intercooler assembly may include a housing and a cooler arranged therein through which charge air may be flowable. The housing may include an insertion opening through which the cooler may be insertable into the housing in an insertion direction transverse to the flow direction of the charge air. The cooler may include a pipe structure through which a coolant may be flowable, first and second end parts opposite each other transverse to the insertion direction, and third and fourth end parts opposite each other transverse to the first and second end parts and parallel to the flow direction, the end parts laterally delimiting and mechanically connected to the pipe structure. The cooler may be mechanically connected to the housing by the first end part, and at least one of the other end parts may be movably attached to the housing. The cooler may be pre-stressed against the housing by the third and/or fourth end part in a direction opposite a deformation of the cooler resulting from cooling of the charge air.

A heat exchanger includes a casing having a first inlet, a first outlet, a second inlet, and a second outlet, and a plate assembly positioned between the first inlet and the first outlet and between the second inlet and the second outlet and at least partially in the casing, the plate assembly is being configured to transfer heat between a first fluid and a second fluid. The heat exchanger also includes a first plenum connecting a first side of the plate assembly and configured to direct the first fluid from first inlet to the plate assembly, and a second plenum connecting a second side of the plate assembly and configured to direct the first fluid from the plate assembly to the first outlet. An exterior of the second plenum is in contact with the second fluid, and the second plenum is configured to resiliently deflect in response to thermal expansion.

An integrated pressure compensating heat exchanger and method of use are provided. The integrated pressure compensating heat exchanger includes an inlet configured to input an internal fluid; a first conductive bellows connected to the inlet, configured to accept the internal fluid from the inlet, configured to transfer heat between the internal fluid and an external fluid, and configured to compensate for a pressure by compressing in length; and an outlet configured to accept the internal fluid from the first conductive bellows and to output the internal fluid.

A heat exchanger, for heating or cooling bulk solids, includes a housing including an inlet for receiving the bulk solids, an outlet for discharging the bulk solids, and a heat exchange chamber disposed between the inlet and the outlet. The heat exchanger also includes spaced apart heat transfer tubes supported within the housing, between the inlet and the outlet, and extending through the heat exchange chamber, for indirect heat exchange of a heat exchange medium in the heat exchange chamber with the bulk solids that flow, by gravity, from the inlet, and through the heat transfer tubes, toward the outlet. The heat transfer tubes include a first end for receiving the bulk solids, and a second end for release of bulk solids. At least one of the first end and the second end is moveable relative to the housing to accommodate thermal expansion or contraction.
