Abstract: A device for thermal regulation, in particular for cooling, for an electrical component that is liable to release heat during its operation, in particular for an electrical energy storage module. The device includes a first plate and a second plate, which is assembled with the first plate, each being delimited by edges, in order to form together a plurality of circulation channels for a heat-exchange fluid, in particular a refrigerant fluid. The plurality of channels define a channel zone, and the two plates are assembled by laser welding, preferably transmission laser welding, at the channel zone. The device includes an additional joining means, which is different than the transmission laser weld and which connects the edges of at least one plate to the other plate.

Abstract: A thermal regulation device for an electrical component that is liable to release heat during operation. The device includes a first plate and a second plate, which is assembled with the first plate, each being delimited by edges, in order to form together a plurality of circulation channels for a heat transfer fluid. The plurality of channels define a channel zone, at least one of the plates is pressed in order to form a portion of the walls of the channels, the assembly of the two plates being carried out by laser welding at the walls of the channels. A zone defining at least partially the perimeter of the channel zone includes an assembly mechanism different from transmission laser welding, the different assembly mechanism is selected from among filler wire laser welding, adhesive bonding, friction stir welding, or a combination thereof.

Abstract: The invention relates to a CO2 biological capture method comprising the implementation of a photosynthesis reaction by cyanobacteria on the hydrogen carbonate ions of a carbonate system comprising calcium, allowing biomass and calcite (CaCO3) to be produced. The invention allows energy valorization and mineral sequestration of CO2.
