Hermetically sealed cooling system, especially for computer processor, has evaporation-condensation cooling cycle with radial pump whose impeller is driven by magnetic coupling to external drive

摘要

Hermetically-sealed cooling system, especially for a computer processor, operates using an evaporation-condensing cooling method and has at least a heat sink, a heat exchanger, a pump for circulation of a coolant, a throttle valve and a non-return valve. The pump is a radial pump that has a drive unit (3) situated outside the hermetic system. The pump impeller (1) is linked magnetically (2) to the external drive unit. An axial, diagonal or centrifugal pump can also be used instead of an externally driven radial pump.
