    摘要： Monitoring of cooling of an electronic component is provided, which includes: determining a current thermal resistance associated with one or more of the electronic component, a heat sink coupled to the electronic component, or a thermal interface coupling the electronic component and the heat sink; and determining, by a processor, whether the current thermal resistance exceeds a set thermal resistance threshold, and responsive to the current thermal resistance exceeding the set thermal resistance threshold, indicating a thermal resistance fault. As an enhancement, rate of change over time of the thermal resistance is determined, and compared against a rate of change threshold, and if exceeding the threshold, a rate of change thermal resistance warning is provided.

    摘要： An apparatus for facilitating servicing of a liquid-cooled electronics rack is provided. The apparatus includes a coolant tank, a coolant pump in fluid communication with the coolant tank, multiple parallel-connected coolant supply lines coupling the coolant pump to a coolant supply port of the apparatus, and a coolant return port and a coolant return line coupled between the coolant return port and the coolant tank. Each coolant supply line includes a coolant control valve for selectively controlling flow of coolant therethrough pumped by the coolant pump from the coolant tank. At least one coolant supply line includes at least one filter, and one coolant supply line is a bypass line with no filter. When operational, the apparatus facilitates filling of coolant into a cooling system of a liquid-cooled electronics rack by allowing for selective filtering of coolant inserted into the cooling system.

    摘要： A method is provided for facilitating cooling of an electronic component. The method includes: providing a refrigerant loop configured for refrigerant to flow through the loop; coupling a compressor in fluid communication with the loop, wherein a first portion of the loop resides upstream of a refrigerant inlet of the compressor, and a second portion resides downstream; and disposing a controllable thermoelectric array in thermal communication with the refrigerant loop. The thermoelectric array is disposed with the first portion of the refrigerant loop at least partially in thermal contact with the first side of the array, and the second portion of the loop at least partially in thermal contact with a second side of the array. The array is controlled to ensure that refrigerant in the refrigerant loop entering the compressor is in a superheated thermodynamic state.

    摘要： Apparatuses and methods are provided for facilitating cooling of an electronic component. The apparatus includes a vapor-compression refrigeration system. The vapor-compression refrigeration system includes an expansion component, an evaporator, a compressor, and a condenser coupled in fluid communication via a refrigerant flow path. The evaporator is coupled to and cools the electronic component. The apparatus further includes a contaminant extractor coupled in fluid communication with the refrigerant flow path. The extractor includes a refrigerant boiling filter and a heater. At least a portion of refrigerant passing through the refrigerant flow path passes through the refrigerant boiling filter, and the heater provides heat to the refrigerant boiling filter to boil refrigerant passing through the filter. By boiling refrigerant passing through the filter, contaminants are extracted from the refrigerant, and are deposited in the refrigerant boiling filter.
