At the same time, the contact part of the verification regulation of rail temperature measurement by the Ministry of Railways in 2008 add the requirement that in rail temperature sensor and detector timing examination source, it is forbidden to use thermal grease, to ensure that it is inconsistent with the state of the actual measurement of rail temperature, which puts forward higher accuracy requirements on the rail thermometer (Goyal, 2014).
As a heat con ductor, it may replace the thermal grease cur rently being used, and as an elec trical con ductor, it may replace today's sol ders.
The ATS-405 sink delivers a thermal resistance of just 0.51[degrees]C/W with thermal grease. This performance provides an 18% margin of safety over the specified thermal resistance.
There are common techniques to manage heat within a device applicable to both rigid and flexible printed circuits, such as adding a metal heatsink on the components, thermal vias to transfer heat from the component side of the board to the opposite side, and thermal grease to facilitate heat transfer from the board to an external frame.
The cooling module is directly mounted on the substrate through layer of thermal grease to avoid air spots and therefore reduce the thermal contact resistance [5, 7].
An innovative silicone-based thermal grease from Fujipoly (Carteret, NJ) delivers a thermal conductivity of 2.6 W/m[degrees]K while exhibiting minimal bleed and evaporation characteristics.
It is imperative that there be no voids or even significant variations in thickness in the adhesive layer, which typically is a thermal interface material or a thermal grease.
One common material that performs these functions is thermal grease, which is inexpensive and effective in eliminating air barriers.
