Problems solved by technology

[0011] In fact, due to its inability to withstand long-term work at high temperatures (typically higher than 650°C), more precisely, the highest heat transfer performance in gas turbines in this case, the plate-pin design and unit design has so far been severely limited

Embodiment Construction

[0079] In the various embodiments described below, only two sets of plates are shown for convenience. However, it will be appreciated that in practice there will be a plurality of such plate sets.

[0080] figure 2 is a perspective view of a part of the core 1 of the recuperator according to the first embodiment of the invention. The core comprises a plurality of stacked or stacked pairs of plates, each pair of plates connected together by a pin passing through it. Such as figure 2 As shown, the partial stack comprises two plate pairs 3 , 5 . As shown in the upper part of the figure, the first board pair 3 includes an upper board 7 and a lower board 9 . The lower plate pair 5 also includes an upper plate 11 and a lower plate 13 .

[0081] In the core, all the plates are substantially planar (ie flat plates) and are arranged at a distance from each other, with their main planes spaced from each other in a parallel manner.

[0082] Accordingly, the plates 7 of the upper ...

Abstract

A heat exchanger comprises a plurality of plates (7, 9, 11, 13) each having first (15, 19) and second (17, 21) heat transfer surfaces on reverse sides. The plates are arranged in a stack with spacings between mutually facing heat transfer surfaces of adjacent plates. Alternate spacings in the stack providing respectively, a first fluid path (51, 52) for a first fluid and a second fluid path (57, 59) for a second fluid. The plates are arranged in a plurality of groups, each comprising at least two plates. Pin means are provided in the form of a plurality of groups of pins (23). The pins of each pin group are arranged to bridge plates of a respective plate group.

Description

technical field [0001] The present invention relates to heat exchangers (or heat exchangers) and their use in various industrial applications. A variety of such applications will be described in more detail below, but use in gas turbine construction constitutes a preferred class of implementation. Background technique [0002] Gas turbines are commonly used in distributed power generation and power transmission. In these and other applications, there are many problems in providing suitable heat exchangers (recuperators) that perform well and are of suitable size, cost and performance. [0003] For air-to-air heat exchangers, a plate-fin or tube-sheet configuration is usually ideal. A traditional tube-sheet heat exchanger consists of a structure in which a fluid flows through a length of tubes that run through a stack of parallel plates. A second fluid flows in the gaps between the plates. [0004] US-A-5 845 399 discloses a carbon fiber composite heat exchanger in which ...
