  • Dynamic scraped surface heat exchanger — The dynamic scraped surface heat exchanger (DSSHE) was designed to face some problems found in other types of heat exchangers. They increase heat transfer by: removing the fouling layers, increasing turbulence in case of high viscosity flow,… …   Wikipedia

  • Dynamic scraped surface heat exchangers — Introduction The most important technologies for indirect heat transfer use tubes (shell and tube exchangers) or flat surfaces (plate exchangers). Their goal is to exchange the maximum amount of heat per unit area by generating as much turbulence …   Wikipedia

  • Heat sink — A heat sink (or heatsink) is an environment or object that absorbs and dissipates heat from another object using thermal contact (either direct or radiant). Heat sinks are used in a wide range of applications wherever efficient heat dissipation… …   Wikipedia

  • heat exchanger — counter current heat exchanger (exchange of heat between blood vessels going to surface structures with vessels going deeper into the body. This exchange preserves core body temperatures and reduces surface heat loss so that the fish can function …   Dictionary of ichthyology

  • Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change …   Wikipedia

  • Surface-mount technology — (SMT) is a method for constructing electronic circuits in which the components (SMC, or Surface Mounted Components) are mounted directly onto the surface of printed circuit boards (PCBs). Electronic devices so made are called surface mount… …   Wikipedia

  • Heat conduction — or thermal conduction is the spontaneous transfer of thermal energy through matter, from a region of higher temperature to a region of lower temperature, and acts to equalize temperature differences. It is also described as heat energy… …   Wikipedia
