Patent ID: 7926553

Claim:
A cooling system for electronic devices, especially computers, comprising: a vapor-distribution and condensate-collection element ( 3 ) and a condenser ( 2 ) with a plurality of condenser pipes ( 6 ) and a block of fins ( 5 ) connecting the condenser pipes ( 6 ); wherein the condenser pipes ( 6 ) are arranged parallel to each other and extend upwards from the vapor-distribution and condensate-collection element ( 3 ) and are closed at their top ends; a plurality of evaporators ( 1 ) fitted and connected with the vapor-distribution and condensate-collection element ( 3 ), at least a first of said plurality of evaporators disposed vertically lower than the condensate-collection element ( 3 ) and at least a second of said plurality of evaporators disposed vertically higher than the condensate-collection element ( 3 ); wherein a first connecting pipe ( 8 ) without a heat pipe structure is fitted between the first evaporator ( 1 ) and the vapor-distribution and condensate-collection element ( 3 ); wherein a second connecting pipe ( 7 ) with an internal heat pipe structure is fitted between the second evaporator ( 1 ) and the vapor-distribution and condensate collection element ( 3 ); and wherein the first connecting pipe ( 8 ) is connected into the vapor-distribution and condensate-collection element ( 3 ) at a height (H) of 0.5 to 1 times a diameter (D) of the second connecting pipe ( 7 ) with said heat pipe structure.
