Embodiment Construction

[0015] The present invention is described in the context of a circulated water cooling system generally of the type designated by the reference numeral 10 in FIG. 1. However, it will be appreciated by those skilled in the art that the embodiments described herein are also applicable to other types of circulated liquid cooling systems, and also to systems with stagnant fluid as in pool-boiling.

[0016] The embodiments depicted in FIGS. 2 and 3 are particularly applicable to cooling system pipe joints of the abutment type in which two similarly sized pipes 40 and 42 separated by a small gap 43 are joined by an internal sleeve 44 having an outside diameter equal to or slightly larger than the inside diameter of the pipes 40 and 42. Although not depicted in FIGS. 2-3, the sleeve 44 or the pipes 40, 42 may be coated with a sealing material that is compressed between the sleeve 44 and the pipes 40, 42 to prevent leakage of fluid circulated therethrough.

Abstract

A leak detection apparatus includes one or more detection devices that envelope the various pipe joints of a liquid circulation cooling system. In one approach, the detection devices include a pair of conductors separated by a wicking material impregnated with a crystalline salt that provides a low resistance electrical path between the conductors in the presence of a leak. In another approach, the detection devices include a pair of dissimilar metal mesh electrodes separated by an electrolyte-impregnated wicking material to form a water-activated battery that energizes an alarm in the presence of a leak. In either case, the electrodes and wicking material may be encased with a water-activated sealing material that hardens in the presence of a leak to contain the leakage.

Description

TECHNICAL FIELD [0001] The present invention is directed to liquid circulation cooling systems for electronic devices and the like, and more particularly to apparatus for detecting, locating and isolating coolant leaks at the pipe joints of such systems. BACKGROUND OF THE INVENTION [0002] Liquid cooling is finding increased application in the electronics industry due to the limited heat dissipation capability of forced air cooling systems and the desire to minimize cooling system noise levels. FIG. 1 depicts a liquid cooling system 10 for one or more heat producing electronic devices 12. The device 12 is typically mounted on a circuit board 14, and its upper surface is secured to a cold plate 16 of cooling system 10 by thermal paste, thermal interface material or other means so that heat generated by the device 12 is conducted to the cold plate 16. The cold plate 16 is provided with inlet and outlet pipes 16a, 16b through which a liquid coolant such as water or a water-glycol soluti...
