Abstract
A closed loop forced liquid cooling system has provision for continuously separating dissolved gas from the cooling liquid. A gas separator is combined with a liquid-gas interface pressurizer to establish favorable temperature and/or low pressure conditions for preferential gas evolution. By preventing bubble formation in liquids cooling electronic and electrical equipment, dielectric breakdown of the cooling liquid is averted.
Claims2
A forced liquid cooling system comprising
- a main cooling duct loop for continuously circulating dielectric cooling liquid in a closed path past heat producing equipment to be cooled and including a pump for pumping said cooling liquid and a heat exchanger for cooling said cooling liquid,
- combined continuous gas separator and liquid-gas interface pressurizer means for pressurizing at least a portion of said cooling liquid with dielectric gas and establishing selected physical conditions to obtain preferential evolution of dissolved gas from said cooling liquid, to thereby prevent the formation of bubbles,
- said combined separator and pressurizer means elevated a considerable height above said main cooling duct loop to establish favorable low pressure conditions for gas evolution, and
- said combined separator and pressurizer means comprising a pressurizer expansion tank for said cooling liquid having a vertical exit duct connecting to a gas storage tank, a vertically oriented condenser mounted to cool the vapor and gas in said exit duct, and means for venting excess pressure in said gas storage tank.
