Technical field
The present invention relates generally to protect operable computer digital data storage device, can be owing to being exposed to the device that causes damage and loss of data in fire or the water.More particularly, the present invention provide for the first time the compactness of operable computer digital data storage device, the shell of fire-resistant and/or water cheaply.Typical computer digital data storage device comprises computer hard disc driver; CD drive, solid state memory device, tape drive; Computer or can read and write numerical data on one's own initiative is so that storage and recover any other device of computerized numerical data.
Because digital data storage unit can be stored the data of staggering amount, therefore, in the disaster of one type of for example fire or floods, losing digital data storage unit more and more becomes catastrophic.A kind of compactness of digital data storage unit of work obviously need be provided, fire-resistant and/or water-fast reliably shell.
Summary of the invention
The invention provides operable computer digital data storage device compactness, cheaply, fire-resistant and/or water-fast shell.The present invention includes several alternative embodiment.All these embodiment are the reliable cheaply shells that the hard disk drive of work will be provided.This embodiment for example comprise band with not with the astomous shell of fan; Band with not with the watertight case of movable opening; Band with not with the free convection shell of movable opening; Have Unitarily molded part supporting, by the molded low-cost shell of gypsum; And have when fire is arranged the path that sealing is used to cool off data storage device, by the shell of expandable or fusible material.
The preferred embodiments of the present invention avoid the use of as at above-mentioned sequence number being the movable opening described in 11/112552 the U.S. Patent application.Here it is for reference to introduce this application.Astomous embodiment of the present invention is also without any need for the checkout gear of fire or cigarette.Removing these parts can make the cost of device reduce greatly.The key of preferred embodiment is to find that enough undersized ventilating opening can prevent the damage that fire causes, and is not having under the situation of fire simultaneously, can allow enough force air to ventilate, with the storage device of cooling work.We are with suffering this notion of prototype test of fire, and finding does not have the storage arrangement of loss of data and hard drive not have serious damage.We believe that when when fire is arranged, Inside Air Temperature begins to raise, and inner air expands and outwards flows out through little a ventilating opening or a plurality of ventilating opening.(when fire begins forced air through ventilating opening fan or air blast loss of power and quit work).The outside mobile obstacle external heat of the air that expands flows into inner chamber from fire through little ventilating opening.This little ventilating opening or a plurality of ventilating opening can be designed to tortuous or labyrinth passage, to reduce to flow into from fire the heat of the outside the inner chamber.
Our discovery is confirmed by following calculating.Theoretical and Boyle the law [(P according to ideal gas
1V
1)/T
1=(P
2V
2)/T
2], suppose that atmospheric pressure is a constant, then the internal capacity of air and the (T that raises in the temperature of Kelvin
Kelvin=T
Celsius+ 273.15) expand with being directly proportional.Suppose that the beginning temperature is that 298K (25 ℃) and end temperature are 373K (100 ℃), then the expection of the cavity volume of air increases about 25%.Therefore, can believe that when the temperature of inner chamber increases by 75 ℃ gradually, 25% of inner chamber air volume will outwards flow out through a ventilating opening or a plurality of ventilating opening lentamente.Size through making inner chamber and ventilating opening is suitable, and we find that an insulation and the chamber that ventilates can be enough fire-resistant, with the loss of data that prevents to cause owing to most of fire.
We do not know the refractory outer cover of any prior art of data storage device initiatively, and in this shell, the ventilating opening on the wall is not having fire all to keep open under the fiery situation with having.Prior art comprises the United States Patent (USP) 6153720 of people's such as Olzak explanation aircraft register.The shell of this register comprises under the normal condition closes, but the ventilating opening of when fire is arranged, opening, phase change, the heat-sink shell fusion is also passed through this ventilating opening and is discharged.If this register falls into the ocean, this ventilating opening authorized pressure equates.People's such as Olzak shell does not have explanation or suggestion to the force air of the digital data storage unit of the work that produces big calorimetric ventilate (or any ventilation).Very simple, it is not suitable for the object of the invention.
Second preferred embodiment of the present invention comprises water-fast " bag " (or the lid) with heat conduction of of surrounding this data storage device.Being somebody's turn to do " bag " and data storage device all is placed in the fire-resistant shell.Heat by this data storage device produces is conducted through being somebody's turn to do " bag " (being preferably metal), and utilizes the whole bag of tricks to be passed to the outside of this refractory outer cover later on.In should " bag " complete submersible entry, and in reaching 30 feet water deeply, protect hard disk drive and data.
Prior art comprises the water-fast and refractory outer cover (referring to people's such as Gelb United States Patent (USP) 4992310) of paper file, but this shell is not suitable for the hard disk drive of work fully.Prior art also comprises the cooling jacket of data storage device, but this cooling jacket is not water-fast (referring to the application 2004/0190255 of the u. s. published of Cheon).
Prior art comprises the relatively large shell of exercisable digital data storage unit, for example the United States Patent (USP) 6158833 of Engler.The heat transfer of the wall of the insulation of this shell utilization through container, the heat that this digital data storage unit that dissipates produces.Because the design of Engler does not provide cooling system any active or fans drive, therefore require relatively large shell.On the contrary, the present invention provides the just shell of a fraction of compactness of Engler shell sizes.In one embodiment, compact size of the present invention mainly is because the force air cooling system that in the Engler device, does not have reaches.
Prior art comprises the other digital data storage unit shell that has " passive " cooling system, for example people's such as Pihl patent 5479341.This shell utilization is through the convection current cooling of the ventilation mouth that partially opens.This technology is " free convection ", because do not adopt fan or other aggressive devices to produce convection current.Kiknis patent 5623597 is used quite complicated, has the passive heat exchanger of sizable heat radiating fin structure.When detecting critical temperature, the insulation injection equipment of this designing requirement trouble is to be full of the fin space.The present invention includes have much simpler as " free convection " embodiment with the design that more strengthens than prior art.
Prior art also comprises the people's such as Kishon that proposed on April 1st, 2004 U. S. application US2004/0064631 number of announcement.People's such as Kishon device utilization is conducted the heat that data storage device produces passively through the screw that extends to appliance cover from atmosphere, (referring to [0021] joint).This technology receives the restriction of the lower heat that transmits through metallic screw.Active provided by the invention, the cooling of fans drive can reach much bigger cooling capacity.
