**3. Motivation**

For many years efforts have been made to create more heat exchangers using various methods to improve heat transfer. Due to the increasing demand for the industry in terms of heat exchange devices, however, they are lower in design and *Assessment of Augmentation Techniques to Intensify Heat Transmission Power DOI: http://dx.doi.org/10.5772/intechopen.101670*

operation than conventional heat exchange devices; advanced heat transfer studies **Figure 2** have become more effective in recent years. Energy-saving and energy consumption also provide a significant incentive for new development processes. It is important that heat exchangers are cohesive and lightweight when building cooling systems for cars and spacecraft. Additional devices are also required for hightemperature power switches (i.e. air-cooled condensers, nuclear fuel rods). This and many other uses have led to the production of various improved heat exchangers.

More heat transfer is greatly increased by retransmission or redistribution of flow to improve efficiency,
