Embodiment Construction

[0026] Electrical and electronic components of the process plant, of the machine tool or of the manufacturing plant that are not located directly in the machine, such as sensors, are housed in separate housings and interconnected. Here, the housing should provide protection against dust and water for the electrical and electronic components in its interior. For this purpose, the housings are divided in terms of protection type or IP degree of protection. In addition, the internal cavity of the housing provides support and structure for the device. A suitable housing air conditioning system provides overheating protection. On request, the housing can also provide protection against electromagnetic influences (EMV), protection against mechanical influences, protection against vandalism and earthquakes (e.g. by using a housing with additional support rods) and protect the surroundings with respect to electromagnetic radiation. The environment is shielded. If necessary, such ho...

Abstract

The invention relates to a switchgear cabinet comprising a closed housing and a cooling device for cooling electrical and / or electronic operating means (4, 34, 36, 38) that can be arranged inside thehousing (2), said switchgear cabinet comprising a first closed cooling circuit (6). The first cooling circuit (6) contains a first cooling medium for removing heat produced during the operation of atleast one of the operating means (4) from the housing (2). The first cooling circuit (6) is connected to a first heat-transfer medium (8, 18) arranged inside the housing (2), for transferring the heatfrom the at least one of the operating means (4) to the first cooling medium, and outside the housing (2), to a second heat-transfer medium (14) for giving off the heat to an outer cooling medium. The second heat-transfer medium (14) is arranged above the first heat-transfer medium (8, 18). The first cooling circuit (6), the first cooling medium and the first and second heat-transfer media (8,18;14) are designed to carry out the heat transport according to the two-phase thermosyphon principle.

Description

technical field [0001] The invention relates to a switch cabinet with a closed housing and a cooling device for cooling electrical and / or electronic components which can be arranged inside the housing. Background technique [0002] Electrical and electronic components of process plants, machine tools or production plants which are not located directly in the machine, such as sensors, are accommodated in separate housings for various reasons. The housing should also provide protection against dust and water for these components in its inner cavity, in addition it should serve for the support and construction of the internal structure, and it should prevent the devices arranged in its inner cavity from overheating, etc. [0003] However, in the design of the shell structure for high protection type, such as the shell structure design for the protection class IP54 or IP65, or the shell structure design for outdoor applications, it is necessary to target the Special measures fo...
