But the question is, is it possible to seal the gaps and submerge it to keep it cooled, and the answer is yes. | |

Reputation: 0 ![]() Rep Power: 0 | Thanks for the data. NOTE: there are sealed HDD's available commercially and for large range of altitudes.. (not specified for oil submersion though... ) I have a requirement to effectively hermetically seal small computer systems (incl HDD) for operational environment reasons - so no snorkels. Tried SSD's but too expensive and cranky ( but hope abounds ) Right now using 2.5" rotating HDDs. BUT... based on your experiences & data... - my first plan is to simply test a 2.5" HDD (one that has concentric rings on cover that flex) and to simply seal the breather hole with appropriate epoxy techniques.. BUT at HDD pressureized at about 1.3atm (for my requirements) Given the oil bath (and my limiting altitudes allowed - for normal weather ranges) then the HDD 'breathing' will be greatly limited and if not just pressurizing the case (still having enough 'air' for flying heads).. with some 'volumn' relief transitioned to case flex. This technique is ESPECIALLY indicated, given the control of both thermal transients (VERY IMPORTANT IN HDD SPECS!) as well as an overall oil-thermal design. Care will also be taken to reinforce the drive electronic penetrations and the frame/case seals (again using epoxy - long experience here and at vacuum/pressure chamber pressures) |

That would provide a small reservoir of air for breathing hole.
