Double-pipe heat exchangers, with their typical U-turn shape, are one of the simplest and cheapest type of heat exchangers used in the chemical process industry. This example studies the cooling of hot oil (130°C) by a cool oil (60°C) entering in counter-current. As the oils flow ... En savoir plus
In a cooling system, a microelectronic component has been identified as the critical link. Since the power is repeatedly switched on and off, the component is subjected to thermal cycling. As a results a crack grows through a solder joint and disconnects the chip from the printed circuit ... En savoir plus
