Industrial heat exchange benefits from energy storage

Can heat exchangers reduce energy consumption?

In this regard, researchers are focusing on designing and developing compact and efficient thermal systems to decrease overall energy consumption. Among thermal systems, heat exchangers (HEXs) find extensive applications in various domains, including domestic, industrial, and commercial purposes [7, 8].

What are heat exchangers used for?

Among thermal systems, heat exchangers (HEXs) find extensive applications in various domains, including domestic, industrial, and commercial purposes [7, 8]. Heat exchangers facilitate the efficient exchange of heat between two or more fluids characterized by different temperatures, all while preventing the mixing of these fluids [9, 10].

Can heat exchangers improve convective heat transfer rates?

The growing demand for energy and the necessity to enhance the efficiency of heat exchangers have triggered numerous studies aimed at improving convective heat transfer rates while simultaneously reducing the size and investment costs of industrial devices.

Do enhanced heat transfer techniques improve the performance of heat exchangers?

The adoption of enhanced heat transfer techniques enhances the performance of the heat exchangers thereby enabling energy saving. The review paper is organized as follows: Section 2 explains the designs and constructions of double pipe, plate heat exchangers, and extended surface heat exchangers.

Why are extended surface heat exchangers better?

The disruption of the boundary layer by extended surfaces promotes better HT, resulting in enhanced overall performance. Higher manufacturing costs compared to traditional heat exchangers. The increased surface area makes extended surface HEXs more sensitive to fouling, imposing regular maintenance to ensure optimal performance.

How does a heat exchanger work?

Internal fins are positioned inside the heat exchanger tubes, thereby increasing the surface area available for heat transfer within the fluid. These fins are in direct contact with the fluid flowing inside the tubes, promoting efficient heat exchange as displayed in Fig. 8, Fig. 9.
