HEAT EXCHANGE SYSTEM FOR THE ELECTRONIC DEVICES LIQUID COOLING (OPTIONS) Russian patent published in 2019 - IPC G06F1/20 H05K7/20 G12B15/02 H01L23/34 H01L23/36 

FIELD: calculating; counting.

SUBSTANCE: invention relates to the field of computer equipment, in particular to heat transfer systems during the electronic devices liquid cooling systems development. Proposed is the heat exchange system for the electronic devices closed type liquid cooling, containing refrigerant circulating in the hydraulically interconnected pump, cooler, plurality of circulation circuits with computing units, where the heat-generating electronic components are located and heat exchange between the heat-generating electronic components and circulating in the heat exchange system and cooled in the cooler refrigerant takes place. All circulation circuits are in-parallel connected by pipelines to the supply and return manifolds so that the first circulation circuit input and output, were at the supply and return manifolds inputs, respectively, along the refrigerant flow, then the second one, and so on. Additionally, there is a feedback pipeline, connecting the return manifold output to the cooler, pump and the supply manifold input. Proposed technical solution allows to balance the hydraulic resistance of all circulation circuits during pumped coolant flow passing through them. In case of any of the circulation circuits disconnection, the same refrigerant flow change takes place in connected to the heat exchange system all other circuits. Teat exchange system may contain plurality of circulation circuits with heat exchangers, where heat exchange from the primary refrigerant to the circulating in the computing units secondary refrigerant takes place. For more accurate balancing in each circulation circuit a balancing valve can be additionally installed. Pump can be built-in into the cooler.

EFFECT: technical result is the refrigerant to the computing units flow rate balancing, and the heat exchange system for the electronic devices liquid cooling hydraulic balancing simplification during its operation.
