COOLING OF POWER RECTIFIERS, FOULING IN EXCHANGERS AND PCHE IN HYDROGEN APPLICATIONS
Heat dissipation for power rectifiers in electronics
Comparison between benefits and disadvantages of water-cooled and air-cooled systems for the dissipation of excess heat generated by power rectifiers in modern electronics. Greater levels of heat transfer efficiency for power demanding environments with liquid cooling and the different maintenance tasks of the two solutions.
Why and how do heat exchangers get dirty, loosing efficiency
Why and how do heat exchangers get dirty, it all depends on the kind of fluids circulating in the exchanger itself. Fluids that tend to create scaling on thermal transfer surfaces or dirty fluids with solid particles in suspension. There are therefore various possible interventions, aimed at always guaranteeing and maintaining maximum thermal transfer efficiency.
Tempco PCHE heat exchangers for hydrogen in ICP magazine
Tempco PCHE exchangers - printed circuit heat exchangers - for hydrogen are featured in the article published in last January's issue of ICP magazine. These special exchangers, obtained through an advanced solid state brazing process, called diffusion bonding, are a key technology for the development of hydrogen solutions with fuel cells, being able to operate in the extreme pressure and temperature conditions required by these systems, a crucial asset to accelerate the green transition in industry and mobility.
What kind of heat exchangers is suitable for hydrogen
Hydrogen technologies involve low temperature treatment and high pressure levels, in order to ensure its efficient storage. For hydrogen applications, especially cooling tasks, plate heat exchangers are therefore the ideal solution, in particular PCHE printed circuit exchangers and special brazed plate exchangers, also used for CO2, able to withstand very high pressures and to operate in a wide temperature range.
