A heat exchanger may include a heat exchanger block including a plurality of flat tubes held at a longitudinal end side in a respective rim hole of an associated tube plate. The respective rim hole may have at least two mutually opposite and substantially straight long sides and at least two mutually opposite narrow sides. A brazed connection may be disposed between at least one of the at least two long sides of at least one of the respective rim holes and a corresponding one of the flat tubes arranged therein, and the brazed connection may have an undulating brazing boundary. At least one of the plurality of flat tubes may include at least one partition. The undulating brazing boundary may have a high point that defines an increased thickness in relation to a plane running through two opposite groove bases disposed in the tube plate.

Arrangement for supporting U-bend tube sections in the high heat environment of steam generators using flat bars. The invention uses a combination of thicker and thinner flat bars to impart a serpentine path to the arc of the normally curvilinear U-tubes. The support system accommodates the dilation and contraction of coolant tubes and other elements caused by the extreme and varying conditions inside a steam generator, and which can cause gaps between coolant tubes and prior art tube support bars. Bars of alternating thickness provide alternating offsets to tensionally push and support each tube on multiple sides and in multiple locations, and this tension keeps the tubes in contact with at least some flat bars on multiple sides regardless of size and shape changes. Support arrangement includes a set of fan bars, each fan bar including thick and thin flat bars projecting up and out from a collector bar.

The present invention relates to a heat exchanger (2) having a jacket (10) through which a first medium (A) can flow and which has at least one first inlet (11) and at least one first outlet (12), at least one tube (30) through which a second medium (B) can flow, the tube (30) being guided through the jacket (10) and having at least one second inlet (31) and at least one second outlet (32), wherein a deflection segment (50) or a plurality of deflection segments (50) are arranged in a row in a longitudinal axis (X) in the jacket (10), wherein the deflection segment (50) is formed from at least two partial sections (51, 52), which are arranged so as to overlap and cross, in areas, transverse to the longitudinal axis (X).

The present invention is a cooling apparatus, and a cooling apparatus according to one embodiment of the present invention comprises: a cooling unit comprising a tube main body formed by extrusion such that a coolant channel through which a coolant flows is formed there-through, and headers which are connected to the respective ends of the tube main body and, when a plurality of the tube main bodies are stacked, a plurality of the headers can be assembled in the vertical direction so as to connect the coolant channels of each of the tube main bodies; double-sided chip modules which are disposed between cooling units such that both surfaces of the double-sided chip modules are able to contact the cooling units; and a heat-radiating adhesion unit which attaches the double-sided chip modules to the tube main bodies, wherein the headers are assembled so as to be in close contact, in the vertical direction, ensuring a set spacing between the tube main bodies and the double-sided chip modules, the set spacing being not greater than the thickness of the heat-radiating adhesion unit.

A heat exchanger includes a casing configured to direct a working fluid therethrough, and at least one heat exchanger (HE) section in the casing. Each HE section includes a pair of spaced supports. The spaced supports include: an upstream support and a downstream support with at least one of them including a coolant carrying body configured to direct a coolant therethrough. A first cross-support couples to and extends between respective upstream and downstream supports; and at least one second cross-support couples to and extends between the respective upstream and downstream supports. Cross-supports are vertically distanced from adjacent cross-supports. A plurality of tube positioners coupled to each cross-support position a plurality of heat exchange tubes extending across a working fluid path through the casing. The tube positioners and the cooling of the cross-supports allows ferritic material to be used for once-through, duct-fired HRSGs.
