Abstract
Abstract A cooling arrangement for the operating components of an electronic system such as semiconductor valves in disk form comprises cylindric heat sinks having the end faces in contact with the faces of adjacent semiconductor valves to establish flow of heat from the semiconductor disks to the heat sinks, an annular vessel formed at the periphery of each heat sink and a radial array of inclined cooling pipes communicating with the interior of the vessel. The vessel is partially filled with a cooling fluid which, during operation of the valve system is in a liquid as well as a vapor phase. The fluid vapor is forced outwardly along the tubes where it is re-condensed along the tube walls and flows back by gravity.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
141 words
In a cooling arrangement, particularly for electronic elements such as semiconductor discs constituting the source of heat to be dissipated, a cooling body having an essentially cylindrical configuration and which is in heat transfer relation with the electronic element to establish a heat sink, an annular shaped vessel surrounding said cylindrical body and in heat transfer relation therewith, said annular shaped vessel being constituted by a peripheral groove in said cylindrical body in conjunction with a cylindrical sleeve which closes off the groove, said sleeve being provided with a circumferentially extending row of openings and a radial array of cooling pipes having their inner ends in communication respectively with said openings in said sleeve, said vessel being partially filled with a cooling medium which during operation of the electronic element is in its liquid as well as in its vapor phase.

Claim 3
Dependent Claim
29 words
A cooling arrangement as defined in claim 1 wherein each end face of said cylindrically configured cooling body iS adapted so that a semiconductor disk lies in contact therewith.
Claim 4
Dependent Claim
30 words
A cooling arrangement as defined in claim 1 wherein the surface of said cooling body which forms part of the inner wall of said vessel is provided with cooling fins.
Claim 5
Dependent Claim
41 words
A cooling arrangement as defined in claim 1 wherein the said cooling pipes forming said array are inclined upwardly at an angle greater than 10* to establish a gravity flow return of fluid from the outer end portions of said pipes.
Claim 6
Dependent Claim
15 words
A cooling arrangement as defined in claim 1 wherein said cooling pipes have wing-shaped profiles.
Claim 7
Dependent Claim
23 words
A cooling arrangement as defined in claim 1 wherein the inner wall surfaces of said cooling pipes are provided with a capillary structure.
Claim 8
Dependent Claim
27 words
A cooling arrangement as defined in claim 6 wherein said capillary structure on the inner wall surfaces of said cooling pipes is established by a wire mesh.
Claim 9
Dependent Claim
44 words
A cooling arrangement as defined in claim 1 wherein two radial arrays of cooling pipes are provided, said arrays being disposed one above the other and opening into said vessel through corresponding upper and lower circumferentially extending rows of openings provided in said sleeve.
Claim 10
Dependent Claim
60 words
A cooling arrangement as defined in claim 8 wherein the cooling pipes of the two radially arrays are offset from each other so that the pipes of one array are aligned with the spaces between adjacent pipes of the other array thereby to ensure optimum cooling by an airstream passing through the arrays parallel to the axis of the arrays.
Claim 11
Dependent Claim
48 words
A cooling arrangement as defined in claim 1 wherein said cooling pipes have a U-shaped configuration, the legs forming each of said pipes being connected respectively to two openings in said sleeve which are offset with respect to each other in the direction of the axis of symmetry.
Claim 12
Dependent Claim
52 words
A cooling arrangement as defined in claim 10 wherein the legs of the U-shaped cooling pipes which are connected into the lower positioned openings in said sleeve have a smaller cross section than the other legs of said U-shaped cooling pipes which are connected to the upper positioned openings in said sleeve.
