Web14.3.4 Heat Exchangers. Heat exchangers are commonly used in medical settings as blood heaters/coolers for open heart-lung machines or for patient heating/cooling for standard surgeries. The purpose of cooling the patient during surgery is to reduce the metabolic load, which lowers the need for larger blood flow rates or ventilation rates. http://physics.bu.edu/~duffy/py105/notes/Heattransfer.html

WebThe significant difference between conduction and convection lies in the way the transfer of heat takes place. In the process of conduction, the heat is transferred when there exists a direct contact between the surface to be heated and the source of heat. As against, in the process of convection, the heat transfer takes place through indirect contact. WebOwing to the fact that the transferred heat is equal to the change in the internal energy, the heat is proportional to the mass of the substance and the temperature change. The transferred heat also depends on the substance so that, for example, the heat necessary to raise the temperature is less for alcohol than for water.
