Benefits of technology

The solution provides high-efficiency, controllable cooling of both air and semiconductor devices within the enclosure, maintaining optimal operating temperatures while avoiding increased airflow and humidity issues, at a lower cost and physical footprint compared to traditional systems.

Problems solved by technology

However, all such prior art blower and / or fan systems encounter a problem, the heat transfer efficiency out of the enclosure is limited by the temperature differential between the air inside the computer enclosure and the air in the room ambient.
However, transfer of heat out of the entirety of the enclosure, rather than just specific semiconductor devices is need for optimal cooling of the computer enclosure; in that the density of switches within a specific semiconductor device is a source of excessive heating and that the density of devices, both electronic and electrical, within the computer enclosure is yet another source of excessive heating.
However, even the conformance of the air circulation system to the standards set for computer drive bays fails to address the need for focused cooling created by the high operating temperatures of currently available high-density semiconductor devices.
The expense of this approach is often prohibitive, as is the physical size and placement of the refrigeration system components.

second embodiment

[0093] Heat flow communication between the cooling fluid within the cooling fluid cooling unit 34 and the heat conductive material comprising the lower surface of the enclosure air cooling unit 26 acts to provide a cool surface for heat exchange with the air circulating within the enclosure air cooling unit 26. The preferred embodiment, created with cost considerations foremost in mind, utilizes simple heat conductive sheet metal for the surfaces between the enclosure air cooling unit 26 and the cooling fluid cooling unit 34, between the cooling fluid cooling unit 34 and the Peltier plate 30, between the Peltier plate 30 and the ambient air heat exchanger 60, and for the construction of the computer enclosure cooling unit housing 1 which serves as the outer walls of all sub-units as well as the upper surface of the enclosure air cooling unit 26 and the lower surface of the ambient air heat exchanger 60. This construction of the computer enclosure cooling unit housing 1 from heat con...

third embodiment

[0095] Cooling of the air within the enclosure air cooling unit 26, whether configured as in the preferred embodiment or in the third embodiment, creates a condensate on the cooled surface(s) where the heat exchange with the circulating air takes place. In the preferred embodiment the lower surface of the enclosure air cooling unit 26 is beveled or sloped toward a condensate drain 37. The condensate drain 37 comprises a tube having its upper end opening in the lower surface of the enclosure air cooling unit 26 and its lower end opening in the upper surface of the ambient air heat exchanger 60. The condensate drain 37 is ideally comprised of non-heat conductive materials, alternatively, the condensate drain 37 may be heat insulated from the heat conductive surfaces that it passes through. Freezing of the condensate within the tube comprising the condensate drain 37 as it passes through the upper surface of the Peltier plate 30 must be avoided. A yet third, and not as desirable, solut...

Description

[0001] This is a continuation of U.S. application Ser. No. 09 / 434,873, filed Nov. 4, 1999.[0002] a. Field of the Invention[0003] The present invention is related generally to the field of computer enclosure cooling units. A substantial problem exists in keeping computer enclosures cooled. Typically a computer enclosure houses numerous semiconductor units, certain motorized units, and power supplies, all of which tend to be in varying degrees inefficient and therefore heat producing. Semiconductor units typically have an optimal temperature operating range at or below room temperature (20 degrees Celsius). Most computer enclosures are air cooled with blowers or fans circulating air from the enclosure into the ambient of the room within which the computer enclosure is located.[0004] More particularly the present invention is related to computer enclosure cooling units that utilize Peltier devices to enhance heat transfer out of the computer enclosure into the air circulated into the r...
