“…Most actively cooled systems utilize rotating components, such as pumps, which compromise reliability. However, an exception can be found in [22], where a liquid metal coolant is driven by a magnetohydrodynamic pump. However, this system comes with its own set of challenges and is not examined here.…”

This paper compares active and passive cooling systems in tidal turbine power electronic converters. The comparison is based on the lifetime of the IGBT (insulated gate bipolar transistor) power modules, calculated from the accumulated fatigue due to thermal cycling. The lifetime analysis accounts for the influence of site conditions, namely turbulence and surface waves. Results indicate that active cooling results in a significant improvement in IGBT lifetime over passive cooling. However, since passive cooling systems are inherently more reliable than active systems, passive systems can present a better solution overall, provided adequate lifetime values are achieved. On another note, the influence of pitch control and active speed stall control on the IGBT lifetime was also investigated. It is shown that the IGBT modules in pitch-controlled turbines are likely to have longer lifetimes than their counterparts in active stall-controlled turbines for the same power rating. Overall, it is demonstrated that passive cooling systems can provide adequate cooling in tidal turbine converters to last longer than the typical lifetime of tidal turbines (>25 years), both for pitch-controlled and active speed stall-controlled turbines.

“…Experimental investigations of liquid metal mini-channel heat sinks aimed at power electronic applications have been reported demonstrating increased cooling performance over traditional cooling mediums [40,41]. Moreover, an adaptive thermal management system based on liquid metal was successfully employed for reducing the thermal stress within the power module structure, and thus, increase its lifetime [42]. It must be noticed that all of the above listed work use an external current source to adjust J to get the MHD pump functioning.…”

The press-pack packaging technology has been adopted in recent years for insulated-gate bipolar transistors (IGBTs) to be utilized in high voltage -high current applications, such as high-voltage direct current (HVDC) electric power transmission. Traditionally, the heat management of such systems is based on water coolant, however, there are numerous challenges associated with that method, such as the requirement to deionize the water to prevent electrical potentials and inherent problems of corrosion and leakage in the cooling piping structure. This paper presents the design and development of a liquid metal heat sink for press-pack IGBTs. The use of a thermal management system based on liquid metal increases the heat dissipation capability without corroding the cooling structure. Analytical work is performed on the design of the heat sink. Moreover, the thermal performance of the heat sink is experimentally validated against a commercial water-based cooling system. The presented results show that the cooling performance of the liquid metal system is increased, whereas the shortcomings of the water-based system are eliminated. Index Terms-Press-pack insulated-gate bipolar transistor (IGBT) power module cooling, junction temperature, liquid metal cooling, magnetohydrodynamic (MHD) pump, high-voltage direct current (HVDC) cooling.
