The gyroscopic stabilizer device (12) is fixedly arranged in connection to a first end portion (31) of the antenna mast (3) and the antenna mast (3) is fastenable to a supporting structure at a second end portion (32) of the antenna mast (3), wherein the gyroscopic stabilizer device (12) is configured to reduce movements in a plane perpendicular to the extension of the antenna mast (3).
Abstract:
The present disclosure relates to a cooling module (1) for cooling heat generating components (13) of high-frequency antenna arrays comprising a first plate (2), a second plate (3) and an intermediate plate (4). Further, the cooling module (1) forms a first flow portion (5) in- between the first and the intermediate plate (2, 4), and a second flow portion (6) in-between the second and the intermediate plate (3, 4). The cooling module (1) further comprises an inlet (7) and an outlet (8) positioned at a proximal area (9) of said cooling module (1), wherein the inlet (7) is connected to the first flow portion (5) and the outlet (8) is connected to the second flow portion (6). Moreover, an overflow portion (10) merges a part of said first and second flow portion (5, 6) at a distal area (9') of said cooling module (1) and at least one thermally conductive rod (11). The cooling module (1) is arranged to transfer a cooling medium from the inlet (7) to the outlet (8) allowing for the cooling medium to transfer the cooling medium from the first to the second flow portion (5, 6).
Abstract:
The present disclosure relates to a system (1) for controlling the cooling of an electronic module (2), the system (1) comprising an electronic module (2) extending in a first (x1) and a second direction (y1), a cooling pipe structure (3) and a leakage device (4). The cooling pipe structure (3) is arranged to transfer a flow of cooling medium, so to cool the electronic module (2), wherein the cooling pipe structure (3) further comprises a muzzle (5) extending outwardly from a circumferential portion (6) of said cooling pipe structure (3) and a coupling portion (7) being mated with an open end (8) of the muzzle (5) wherein said leakage device (4) comprises a leak collecting means (9) circumferentially enclosing a mating interface (10) of the muzzle (5) and the coupling portion (7), so to collect any leakage from the cooling pipe structure (3). The leakage device (4) further comprises a transporting portion (11) extending in-between the leak collecting means (9) and an analysis reservoir (12), so to lead any leakage collected in the leak collecting means (9) to said analysis reservoir (12).
Abstract:
The present invention refers to a cooling device for providing cooling capability of adjacent structures comprising: a hollow chamber, an inlet and a chamber outlet, wherein the inlet, the chamber and the chamber outlet are configured such that fluid flow may enter via the inlet, pass through the chamber, and exit via the chamber outlet. The chamber is divided into a distribution chamber and a cooling chamber by a partitioning member, wherein the inlet is fluidly connected to the distribution chamber and the chamber outlet is fluidly connected to the cooling chamber. The partitioning member comprises at least a first and a second constriction passage, wherein the first constriction passage has a first predefined cross sectional flow area and the second constriction passage has a second predefined cross sectional flow area. The sizes of the predefined at least first and second cross sectional flow areas of the at least first and second constriction passages are controllable, whereby the distribution of fluid flow from the distribution chamber to the cooling chamber via the respective constriction passage is controllable.
