His work focuses on improving the efficiency and functionality of heat exchangers, which are essential components in various industrial applications.

Latest Patents

One of Jacques De Lallee's latest patents is a heat exchanger that comprises a first enclosure where heat is supplied. This enclosure is in thermal contact with at least one second enclosure, where a cold heat transfer fluid enters in a liquid state. The design includes a pipe within the second enclosure that discharges the fluid as vapor or a liquid-vapor mixture. This innovative design incorporates a filling that regulates the outflow of fluid, allowing for the partial transformation of the fluid into vapor, which escapes through strategically placed holes in the pipe.

Another significant patent is the thin-film heat exchanger, which features at least one heat-transfer wall separating a hot primary fluid from a secondary fluid to be heated. The heat-transfer wall can be a vertical cylinder with a wavy profile or a vertical rectangular plate with wavy corrugations. This design allows for the creation of leak-tight compartments that alternate between receiving primary and secondary fluids, enhancing the efficiency of heat transfer.
