Abstract
An outdoor information processing device comprises a housing. The housing comprises a hollow interior volume sealed air-tight from an exterior environment and heat dissipation structures on an exterior of the housing. A coolant is disposed in the hollow interior volume of the housing. A portion of the coolant is in a liquid phase collected in a pool in the housing and a portion of the coolant being in a vapor phase above the pool. An information processing system board comprising electronic components is disposed in the hollow interior volume and immersed in the pool of the liquid phase of the coolant. The coolant is configured to transfer heat from the electronic components into the housing via the coolant going through a repeated phase-change cycle.
Claims20
An outdoor information processing device, comprising:
- a housing comprising:
- a hollow interior volume sealed air-tight from an exterior environment;
- and
- heat dissipation structures on an exterior of the housing;
- a coolant disposed in the hollow interior volume of the housing, a portion of the coolant being in a liquid phase collected in a pool in the housing and a portion of the coolant being in a vapor phase above the pool;
- and
- an information processing system board comprising electronic components disposed in the hollow interior volume and immersed in the pool of the liquid phase of the coolant,
- wherein the coolant is configured to transfer heat from the electronic components into the housing via the coolant going through a repeated phase-change cycle.
A system, comprising:
- an outdoor information processing device, the outdoor information processing device comprising:
- a housing, the housing comprising:
- a housing body defining a hollow interior volume;
- a cover to engage with the housing body to seal the hollow interior volume air-tight from an exterior environment;
- and
- heat dissipation structures on an exterior of the housing;
- a coolant disposed in the hollow interior volume of the housing, a portion of the coolant being in a liquid phase collected in a pool in the housing and a portion of the coolant being in a vapor phase above the pool;
