Carbon Fiber Sheet Prototype Challenges Thermal Grease
Sony Chemical & Information Device Corp. displayed a prototype of a sheet whose thermal conductivity it claims is equivalent to that of thermal grease and has a longer life span. The sheet, known as EX20000C, uses a combination of silicon and carbon fibers to produce a thermal conductive layer that is between 0.3 and 2mm thick and has a thermal resistance rating of … [Read more...]
Thermal Endurance Test Procedures Standard
IEC 60034-18-31:2012 describes thermal endurance test procedures for classification of insulation systems used in a.c. or d.c. rotating electrical machines with indirect cooling and form-wound windings. These test procedures are intended to compare the thermal endurance performance of the mainwall insulation between conductor(s) and ground and, where required by the design of … [Read more...]
New Thermally Conductive Silicone Thermal Interface Material
NuSil Technology LLC presents EPM1-2493, a low-viscosity, low modulus silicone elastomer with a nominal thermal conductivity of 1 W/mk. Offering bond lines as thin as 5 microns, EPM1-2493 can be used to adhere materials with differing coefficients of thermal expansion (CTE) for significant stress reduction during thermal cycling. EPM1-2493 does not have the typical paste-like … [Read more...]
3200 BTU Thermoelectric Air Conditioner
EIC Solutions has introduced a 3,200 BTU thermoelectric air conditioner. The new air conditioner employs 50 percent more thermoelectric chips (TECs) with a minimal change in the overall dimensions of the unit. The footprint is identical to the 2,500 BTU model allowing for simple changeovers to achieve increased cooling capacity in existing applications or minimal design changes … [Read more...]
