Cabinet with modules that has a thermosiphon cooler arrangement

摘要

Power converter cabinet (400), comprising: a cabinet housing (406) comprising a first hole (502) for receiving a stream of cooling air, and comprising a second hole (520) for releasing the stream of cooling air thereafter in an operating state of the cabinet (400); at least two power converter modules (102), each module (102) comprises a guide structure (615) to guide the cooling air with an inlet (614) and an outlet (616) to guide the cooling air to through each module (102); wherein the at least two power converter modules (102) are arranged in the cabinet housing (406) so that a greater part of the cooling air stream flowing through the first hole (502) of said housing The cabinet (406) is divided into partial streams of cooling air, at least some of the partial streams are allowed to flow entering its dedicated module (102) through the inlet (614) through the dedicated module (102) to the outlet (616) of the dedicated module (102) respectively so that at least two of the partial streams of cooling air are connected in parallel with each other and after that they leave the cabinet together through the second hole (520) of the housing cabinet (406) in an operating state of the cabinet (400); wherein at least two of said at least two power converter modules (102) each comprise a thermosyphon cooler (600) housed within the guiding structure (615), said thermosyphon cooler comprises an evaporator (604 ) to receive a first heat load generated by at least one electrical and / or electronic component (202, 610) of each module (102) in an operating state of each module (102), and said thermosiphon cooler (600) comprises a condenser (602) for transferring a major portion of said first heat load to said cooling air stream in an operating state of the cabinet (400).
