A liquid cooling apparatus for use with electronic equipment includes a frame adapted to fit in a chassis with electronic equipment. An inner container and outer container are attached to the frame. A liquid inlet is disposed in the frame and has an opening in liquid flow communication with the inner container. A liquid outlet is disposed in the frame and has an opening in liquid flow communication with the inner container. A vacuum outlet is disposed in the frame and coupled to a space between the inner container and the outer container. A detector is coupled to the vacuum outlet and configured to detect air and/or liquid escaping from the vacuum outlet. Advantages of the invention include the ability to cool electronic equipment while guarding against accidental leaks in the cooling apparatus. The invention is also applicable to any process or system where thermal transfer is needed and leaks are to be protected against. This includes, but is not limited to, heating, cooling, or stabilizing the temperature of chemical, biological, or physical processes in medical, scientific, testing or processing equipment.

Liquid cooling apparatus for use with electronic equipment

A tracking system comprising multiple satellite units and a master unit for selectively and individually locating each satellite unit. Each satellite unit receives a search signal from the master unit and transmits a response signal to the master unit when the search signal contains a search identity code which matches a unique identity code of the satellite unit. The master unit has user controls for selecting any one of the satellite units to be located and a memory for storing the unique identity code of each satellite unit. The master unit also has an indicator circuit for indicating the strength of the response signal and a display and speaker for visually and audibly indicating the strength to a user. The master unit is programmed such that when the user selects one of satellite units to be located, the master unit transmits a search signal having a search identity code which matches the unique identity code of the selected satellite unit. The tracking system also preferably includes a passive re-radiating strip to be attached to an object to be tracked. The strip receives signals from the master unit at a fundamental frequency and re-radiates the signals at a multiple of the fundamental frequency. The master unit indicates the strength of the re-radiated signals to the user, enabling the user to locate the strip.
