Abstract (en)
[origin: WO2020260842A1] The invention mainly relates to a cryogenic cooler comprising a cold region, a heat-transfer fluid circuit, the cold region being positioned in the circuit, an application heat exchanger configured to exchange calories with a device to be cooled, characterised in that the cooler comprises at least one passive non-return valve fluidly connected to the cold region, the heat exchanger comprising at least one first fluid inlet positioned downstream of the non-return valve in the flow direction of the heat-transfer fluid, the heat-transfer fluid circulating from the end of the cold region.
