Problems solved by technology

[0005] In power plants, there is the disadvantage that the heat exchanger consisting of distribution pipes and cooling grids can only be designed to a certain length, because otherwise the excessive weight would prevent installation
Furthermore, in order to obtain a large enough surface and to provide sufficient flow gaps to dissipate heat, the cooling grid requires a large space

Embodiment Construction

[0024] In the following figures, three embodiments of heat exchanger assemblies forming the heat exchanger of the present invention are depicted. Here, the same components are provided with the same reference numerals.

[0025] FIG. 1 is a cross-section of two stacked sandwich heat exchanger assemblies 5 comprising a distributor 1 and a heat exchanging element 3 of a first embodiment. The distributor 1 is formed from a complete tube 2 with a flat steel hollow section and coated with aluminium. This thin-walled steel hollow section is only a few millimeters thick. As heat exchange element 3 a metal sponge 4 of open-celled aluminum foam is foreseen. Metal sponges 4 and complete tubes 2 are alternately layered on top of each other and welded together. Alternatively, the components of the heat exchanger assembly 5 can also be glued.

[0026] As shown in FIG. 1 , the circular side of the complete tube 2 protrudes from the metal sponge 4 . Thus, sufficient space to connect adja...

Abstract

Heat exchanger for industrial systems, especially power plants, comprises at least one distributor for a fluid medium and at least one heat exchanger element fixed on the distributor. The heat exchanger is formed by a sandwich arrangement of distributors and heat exchanger elements consisting of metal foam bodies (4). The distributors consist of a pipe or at least interconnected half pipes (2''). Adjacent pipes / half pipes are connected to each other via the metal foam bodies. - Preferred Features: The metal foam body consists of an aluminum foam.

Description

technical field [0001] The invention relates to a heat exchanger for industrial plants, in particular for power plants, having at least one fluid medium distributor and at least one heat exchanger element attached to said distributor . Background technique [0002] Heat exchangers in power plants generally comprise distributor tubes, the outer surface of which is at least partially covered with a cooling web. For example, such heat exchangers are used as air-cooled condensers. The use of heat exchangers as cooling devices is also known in chemical and food industry plants. [0003] In general, heat exchangers can dissipate energy or supply energy. Usually, the energy exchange takes the form of heat exchange from the high temperature fluid medium to the low temperature fluid medium in the distributor tube. In this process, the hotter medium is cooled while the cooler medium is heated at the same time. In the power generation equipment, the energy exchange process is carr...
