摘要： A filter system including a method for self cleaning the filter system of an electronic equipment enclosure where air flow is monitored either by monitoring fan performance of air flow velocity through the enclosure. The system includes two filters elements, an upstream ASHRAE or HEPA filter element to block particulate matter and a downstream PTFE filter element to block water vapor. The ASHRAE or HEPA filter element is relatively inexpensive and easy to clean. The PTFE filter element is more expensive and difficult to clean. Thus, the cheaper filter is used to protect the more expensive filter from contaminants and to increase its useful life. The method of self cleaning includes stopping the fan when a signal is received indicating a predetermined resistance to air flow which is a function of blockage of the filter elements, thereafter operating the fan at an increased rotational velocity to determine whether the fan itself is malfunctioning, thereafter slowing and stopping the fan to allow the fan to be reversed, rotating the fan in reverse for a predetermined period of time, such as five minutes, thereafter slowing and stopping the fan and returning the fan to its usual rotational velocity and direction. If the resistance to air flow is still above a predetermined level, the fan is again slowed, stopped and reversed and then returned to normal operation. The reversal operation can be conducted a multiple number of times, however, after a predetermined number, a signal is sent requesting maintenance
摘要翻译： 一种过滤系统，包括用于自动清洁电子设备外壳的过滤系统的方法，其中通过监测通过外壳的空气流速的风扇性能来监测气流。 该系统包括两个过滤器元件，用于阻挡颗粒物质的上游ASHRAE或HEPA过滤元件和用于阻挡水蒸气的下游PTFE过滤元件。 ASHRAE或HEPA过滤元件相对便宜且易于清洁。 PTFE过滤元件更昂贵，难以清洗。 因此，更便宜的过滤器用于保护更昂贵的过滤器免于污染物并增加其使用寿命。 自清洁方法包括当接收到指示预定的阻力的过滤器元件的空气流动的信号时停止风扇，此后以增加的转速操作风扇以确定风扇本身是否发生故障， 然后减速并停止风扇以允许风扇反转，将风扇反向旋转预定的时间段（例如五分钟），然后减慢并停止风扇并使风扇返回到其通常的旋转速度和方向。 如果气流阻力仍高于预定值，则风扇再次变慢，停止并反转，然后恢复正常运行。 反转操作可以进行多次，然而，在预定数量之后，发送请求维护的信号

摘要： A more efficient cooling system for densely packed electronic components for use in an out-of-doors equipment enclosure. An array of cooling assemblies are placed on heat generating components mounted to printed circuit boards mounted in enclosure racks. Each board has a manifold for intake and exhaust of refrigerant, and larger rack manifolds are substituted for rails and are attached to a backplane. A hybrid package including a ceramic hybrid power module and an attached array of cooling assemblies provide even more density of components and improved cooling.

摘要： An equipment cabinet mounted on a concrete pad. The cabinet includes an upper equipment chamber, a lower back-up battery chamber and a heat exchanger. Ambient air is drawn across batteries in the lower chamber before being drawn into the heat exchanger to help cool electronic components in the upper chamber. Air in the upper chamber is separate circulated through the heat exchanger. A cold plate is placed beneath the batteries and is connected to a refrigeration system. A heating pad is located below the cold plate and is separated from the concrete pad by insulation. The cold plate and the heating pad are used to maintain the batteries at about 25° C. regardless of ambient temperatures so as to extend the useful lives of the batteries.
