CONTAMINANT COLD TRAP FOR A VAPOR-COMPRESSION REFRIGERATION APPARATUS

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 and a compressor 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 cold trap coupled in fluid communication with the refrigerant flow path. The cold trap includes a refrigerant cold filter and a coolant-cooled structure. At least a portion of refrigerant passing through the refrigerant flow path passes through the refrigerant cold filter, and the coolant-cooled structure provides cooling to the refrigerant cold filter to cool refrigerant passing through the filter. By cooling refrigerant passing through the filter, contaminants solidify from the refrigerant, and are deposited in the refrigerant cold filter.
