“…In the first step of the manufacturing process, fine grooves are photochemically etched into one side of a flat metal plate forming the fluid passages. The etched-out plates are thereafter alternately joined by diffusion bonding, which is the second step and results in compact, extremely strong, all-metal heat exchanger cores [9]. The diffusion bonding process includes a thermal soaking period to allow grain growth, thereby essentially eliminating the interface at the joints, which in turn gives base-material strength and very high pressure containment capability throughout the entire exchanger, in addition to the avoidance of corrosion cells.…”

In recent years, thermal control systems performance has improved in numerous ways due to developments in control theory and information technology. Efforts have been made to produce more efficient heat exchangers by employing various methods of heat transfer enhancement. An increase in heat exchanger performance can lead to a more economical design of heat exchanger which can help to make energy, material & cost savings related to a heat exchange process. Compact heat exchangers (CHEs) technologies are expected to be one of the solutions for the new generation heat exchanger. In this paper are presented of the compact heat exchanger, Plate-fin heat exchanger, and Printed Circuit Heat Exchanger. And computation fluid dynamic is used which offers an alternative to the quick and inexpensive solution for the design and optimization of compact heat exchangers.

“…In spite of the large number of publications with regard to the simulation of household refrigeration systems, optimization studies are rare, and the few ones available are focused on a single component [22][23][24][25]. Waltrich et al [26] presented a model-based methodology to optimize the energy performance and cost of a refrigeration system by varying not only the heat exchangers (condenser and evaporator) characteristics but also the compressor size.…”

“…Stewart et al [5] developed a refrigeration system emphasizing the details of the finned tube condenser using an optimization algorithm focused on efficiency. The research found that the optimization process makes it possible to determine an ideal condenser with the same performance as a traditional system, which has a cost of 23% higher.…”

The thermal efficiency of heat exchangers was applied for theoretical analysis of the thermal performance of a finned heat pipe heat exchanger (FHPHE) used as an auxiliary device to control the temperature and quality of the air conditioning in operating rooms. The theoretical analysis performed is punctual and distributed. It is divided into three aspects: analysis of the evaporator section, analysis of the condenser section, and analysis of the heat exchanger in terms of overall performance. The distributed procedure contrasts with the theoretical-experimental study, which uses the concept of thermal effectiveness (ε-NTU) for global heat exchanger analysis. The developed approach considers the number of heat pipes, the number of fins, and the flow rate variation at the inlet of the heat exchanger as fundamental parameters for determining the thermophysical quantities of interest. Theoretical values were determined for the average velocities, Nusselt numbers, thermal effectiveness, heat transfer rates, and exit temperatures. The localized theoretical-experimental comparisons are consistent, and the absolute relative error for the global heat transfer rate ranges from 0.5% to 35%.
