A condenser (28) is connected at the top (31) to a riser (22) and at the bottom (32) to a downpipe (23). Below the condenser (28), a vertically disposed, plate-shaped element (13) is arranged, there being formed along the two vertical edges of this element the conduits (22, 23) and, between these, s
A condenser (28) is connected at the top (31) to a riser (22) and at the bottom (32) to a downpipe (23). Below the condenser (28), a vertically disposed, plate-shaped element (13) is arranged, there being formed along the two vertical edges of this element the conduits (22, 23) and, between these, several evaporators (15), separated from one another by perforations (17), for transferring the heat loss of the electrical elements to a liquid. Each of the evaporators (15) is connected at one end at the top (18) with the riser (22) and at the opposite end (19) at the bottom with the downpipe (23). The condenser (28), the conduits (22, 23), and the evaporators (15) constitute a unit sealed in a pressure-proof fashion which is filled with the liquid, that can be evaporated in the evaporators (15) by the heat loss and can be condensed in the condenser (28), to such an extent that the liquid volume lies above the uppermost evaporator (15) and below the condenser (28) or in the lower portion of the latter. The element (13) forms the rear wall of an electronic equipment rack (14), each evaporator (15) being in heat-conductive connection with the electrical elements arranged in a tier of the rack.

Apparatus for dissipating the heat loss of a plurality of assemblies of electrical elements (10) arranged in tiers in superimposed relationship, comprising a plate-like element (13) consisting of two sheets (134, 137), said two sheets (134, 137) joined together in superimposed pressure-sealed relati
Apparatus for dissipating the heat loss of a plurality of assemblies of electrical elements (10) arranged in tiers in superimposed relationship, comprising a plate-like element (13) consisting of two sheets (134, 137), said two sheets (134, 137) joined together in superimposed pressure-sealed relationship forming therebetween a plurality of mutually spaced evaporator cavity means (15; 135) arranged one above the other substantially along the length of said plate-like element, and forming therebetween a first conduit (22) and a second conduit (23) extending substantially along the length of said plate-like element, all of said evaporator cavity means (15; 135) being connected in parallel communication to one another between said first and said second conduits (22, 23), thermally conductive means (12, 50, 51, 112), each of said evaporator cavity means (15; 135) being respectively connected by said thermally conductive means with the assembly or assemblies of electrical elements arranged in a tier, a condenser (28) arranged at a higher level than the topmost evaporator cavity means (15; 135) of said plurality of evaporator cavity means, said condenser (28) having an inlet (31) connected to said first conduit (22) and an outlet (32) connected to said second conduit (23), said condenser (28), said evaporator cavity means (15; 135) and said first and second conduits (22, 23) constituting a unit sealed in a pressure-proof fashion, an evaporable liquid filling said unit to such an extent that the topmost evaporator cavity means (15; 135) of said plurality of evaporator cavity means is filled entirely or at least partially with said evaporable liquid, and the condenser (28) is filled not at all or at most partially with said evaporable liquid.
