Cryogenic heat exchangers for process cooling and renewable energy storage: A review

Analysis of Supercritical Carbon Dioxide Heat Exchangers in Cooling Process

Matrix heat exchangers and their application in cryogenic systems

The necessity of high effectiveness in a small volume has led to the development of perforated plate matrix heat exchangers (MHE) for cryogenic applications. Although the basic principles have remained the same, the techniques of fabrication and bonding have changed considerably during the last four decades. With the introduction of all metal construction, these exchangers are finding increasin...

Thermal Design Considerations and Performance Evaluation of Cryogenic Tube in Tube Heat Exchangers

Heat exchangers are the most important equipment in refrigeration processes. Design and modeling of heat exchangers operating at low temperatures are different from other regular heat exchangers. This study includes two sections. In the first section, design and modeling considerations needed for evaluating the real thermal behavior of heat exchangers at low temperatures were discussed. The...

Review of Fractal Heat Exchangers

Nature has inspired many scientists and engineers to solve problems through observation and mimicry. One such example is heat transfer enhancement. The enormous natural heat and mass transfer phenomena have led engineers to seek solutions to heat transfer enhancement problems from nature. Fractal geometries are found in respiratory and vascular systems of plants and animals, such as blood vesse...

Passive cooling methods for energy efficient buildings with and without thermal energy storage – A review

This paper reviews the various possible methods of passive cooling for buildings and discusses the representative applications of each method. Passive cooling techniques are closely linked to the thermal comfort of the occupants, and it is possible to achieve this comfort by reducing the heat gains, thermal moderation and removing the internal heat. In the present review the various methods ado...
