Vapor-compression cooling can be found in virtually any home, such as in air conditioners that remove heat from our homes and in refrigerators that store our food. The history of vapor-compression goes back to 1805 where Oliver Evans, an American inventor, described a closed vapor-compression refrigeration cycle for producing ice. The first working vapor-compression … [Read more...]
Advanced Cooling for Power Electronics
Power electronics devices such as MOSFETs, GTOs, IGBTs, IGCTs etc. are now widely used to efficiently deliver electrical power in home electronics, industrial drives, telecommunication, transport, electric grid and numerous other applications. This paper discusses cooling technologies that have evolved in step to remove increasing levels of heat dissipation and manage junction … [Read more...]

New Super-Sensitive Temperature Sensor Accurate to +/-1.5°C
Omron Electronic Components has extended its non-contact MEMS thermal sensor range with a new narrow-field version specifically designed to provide accurate non-contact measurements of an objects’ surface temperature for industrial control, medical and building automation systems. The Omron D6T-1A-02 is a super-sensitive infra-red (IR) temperature sensor that makes … [Read more...]
Someday Humans Will “See” The Heat!
Many biological creatures are enabled with the ability to “see” the heat – reptiles, for example, effectively use this ability to detect the size of the heat-emitting object and its range. Other biological entities, including mammals, are enabled with the ability to perceive heat by a process known as Thermoception or Thermoreception. As humans, we are capable of sensing … [Read more...]
