Bruce Guenin Associate Technical Editor, Electronics Cooling INTRODUCTION The previous column, "Use of JEDEC Thermal Metrics in Calculating Chip Temperatures (without Attached Heat Sinks)" dealt with the application of JEDEC thermal metrics to IC packages that do not have heat sinks attached to them [1]. The methods are applicable to prediction of the junction … [Read more...]
Cooling Fans for 1U Rack Applications
Thermal management product designer US Tech has released three new high performance fan series for use in 1U rack applications. The 36mm model produces 24.16 CFM of air volume and 67.52 mm-H2O pressure. In addition, its adherence to the 1U spec of 1.75” (44.45mm) outside to outside tall will leave enough height to design a FRU (Field Replaceable Unit) if desired. The 38mm and … [Read more...]
Heat Sink Series Provides Modular Cooling Options for Electrical Components
Ohmite Manufacturing, a provider of thermal solutions and resistors, has released its new B60/C60 heat sink system ideal for use with high power density and small size (3U or 4U) electronic packaging with forced convection. The new B60/C60 heat sink system provides designers with a variety of cooling options for up to six TO-246 or TO-264 devices, such as TO-247 and TO-264 … [Read more...]
Cooling Fans and Accessories Protect Critical Components
NTE Electronics has released a new line of cooling fans and accessories to protect critical electronic components from premature failure due to heat. Available in five different sizes—40x40mm, 60x60mm, 80x80mm, 92x92mm and 120x120mm—the new AC and DC fans from NTE Electronics utilize a propeller to create a large airflow in the direction of the axis, moving the air in a … [Read more...]
Fansinks for High Temperature Applications
CTS Corporation has announced the release of new fansinks for high temperature applications. Designed to absorb and disperse heat away from high temperature devices, the FHS series features an operating temperature range of -10°C to 90°C, calculated MTTF @ 90°C: 86,858 hours (GEM, 90% confidence) and various package sizes to fit different applications. The FHS series is … [Read more...]
