The pace of development in the telecommunication fields is accelerating in all aspects of the business. In particular, switching/signal processing equipment is continuously increasing in capabilities, and more importantly, heat dissipation. The problem starts at the board/sub-component level and grows to the system level. The equipment often must be housed in enclosures that more often than not will be placed outdoors. Electronic telecommunications equipment has traditionally been housed in large buildings, smaller buildings (sheds) and outdoor cabinets. The cooling of this facilities has been carried out by and large using traditional methods. However, in many new systems being developed and deployed in near future such as Broadband ISDN, cellular and/or cable, heat dissipation densities has increased substantially.
Most telecommunications electronic systems do not include environmentally hardened designs, the enclosure then must provide an environment in which they can survive. To meet the demands of protecting equipment in the outdoor environment, the industry has been pushing for sealed designs. These allow for little or no exchange of cabinet air with the outside air. This is accomplished with near airtight construction, high pressure door closure designs and closed loop thermal systems.
MJM Engineering can help you design thermal management systems for outdoor and indoor telecom systems.
