Embodiment Construction

[0038] The invention relates to a manifold 2 for a heat exchanger 1 and to a heat exchanger 1 comprising said manifold 2 . Within the heat exchanger 1, fluids from two different fluid sources flow to each other through interleaved, isolated parallel channels. Heat exchanger 1 is especially used in advanced heat treatment systems, but can be applied in other fields, such as high temperature flue gas heat recovery, high temperature process fluid energy recovery, corrosive chemical fluid energy recovery, chemical reactor energy saving, carbon black production process, high temperature Ericsson cycle (indirect combustion Joule cycle), high temperature heat recovery, chemical attack, fouling gases, e.g. in the steel industry, and various petrochemical applications. These fields are provided as examples, and the application of the heat exchanger 1 is not limited to these fields.

[0039] In a preferred embodiment, the heat exchanger 1 consists of a first manifold 2a connected to a ...

Abstract

The present invention generally relates to manifolds for parallel flow heat exchangers and heat exchangers incorporating the manifolds. The manifold includes a first plurality of channels having a first opening facing a first direction and a second opening facing a second direction different from the first direction. The manifold also includes a second plurality of channels interleaved with the first plurality of channels, the second plurality of channels having third openings facing a third direction and fourth openings facing a first direction, wherein the third direction Different from the first direction and the second direction.

Description

technical field [0001] The invention relates to a manifold for a parallel flow heat exchanger and a heat exchanger comprising said manifold. Background technique [0002] Heat exchangers are used in many systems ranging from automobiles to air conditioning units to energy recovery units in many advanced heat treatment systems. [0003] Traditionally, the design of a heat exchanger must take into account various factors. For example, fouling can lead to increased pressure drop and reduced heat transfer rate, which can adversely affect heat exchanger efficiency. As another consideration, heat exchangers will inherently experience temperature changes. Additionally, heat exchangers may be subject to high velocity fluid (gas or liquid) flow with particle loading, increasing system wear rates in certain areas. Corrosion problems are exacerbated when heat exchangers operate at high temperatures. Similarly, fluids flowing through a heat exchanger may contain acids or other corro...
