Heat exchangers primarily serve to transfer heat from one fluid to another. This is a fundamental function in various cooling systems where efficient temperature control is essential. By facilitating this heat transfer, heat exchangers play a crucial role in maintaining optimal operating conditions for equipment and processes.

In many applications, this involves allowing a hot fluid to lose heat to a cooler fluid, thereby effectively cooling the first fluid and heating the second. This process is vital in areas such as HVAC systems, refrigeration, and industrial processes.

While other functions like removing contaminants, storing thermal energy, or regulating flow rates are important in different contexts, they do not capture the primary purpose of heat exchangers. Instead, these components are specialized for their role in heat transfer, making option B the most appropriate choice.
