Title:
COOLING SYSTEM FOR ELECTRONIC COMPONENT RACKS
Document Type and Number:
WIPO Patent Application WO/2023/088865
Kind Code:
A3
Abstract:
Cooling system for a multi-unit electronic apparatus stack (1) comprising a plurality of stacked electronic units (3), the cooling system comprising a plurality of unit cooling systems (6) incorporated in, on or between each electronic unit, each unit cooling system (6) comprising one or more fluid flow circuits (13) configured as: - a pulsating heat pipe (PHP) including a pipe (34) having one or more channels (36) therein containing a coolant fluid, the pipe (34) extending between a condenser end (16) and an evaporator end (15), or - a thermosyphon (LTS) cooling system comprising pipes (14a, 14b) extending between a condenser end (16) and an evaporator end (15); the cooling system (2) further comprising a stack cooling system (4) comprising a principal condenser (12) and a fluid flow circuit (8) including a downcomer (8a) and a riser (8b) configured as a loop thermosyphon (LTS) cooling system, the riser comprising a riser pipe (24) extending vertically across a plurality of stacked electronic units (3), each of the unit cooling systems (6) comprising a thermal interface coupling (16) thermally coupled to the riser pipe (24), the fluid flow circuits (13) of the unit cooling systems being independent from the fluid flow circuit (8) of the stack cooling system (4).
