Embodiment Construction

[0048] figure 1 A schematic diagram of a converter 1 according to the invention with heat exchanger channels 5 is shown.

[0049] The converter 1 has a converter housing 2 which has a first interior 3 and a second interior 4 . The first interior space 3 is arranged separately from the second interior space 4 . The first inner space 3 can be hermetically sealed with respect to its entire surroundings, thereby forming a hermetically sealed space.

[0050] In this case, a part of the first interior space 3 protrudes into the second interior space 4 and forms heat exchanger channels 5 . The converter 1 can be operated such that a gaseous heat flow circuit 6 is formed in the first interior space 3 . The formation of the gaseous heat flow circuit 6 in the first flow direction 9 is supported here by a first flow generator 11 , for example an electric fan.

[0051] During operation, the gaseous heat flow circuit 6 absorbs a first loss of heat from the first converter part 19 , for...

Abstract

The invention relates to a converter (1), which comprises a converter housing (2) having a first interior (3) and a second interior (4), the first interior (3) being arranged separately from the second interior (4), and part of the first interior (3) protruding into the second interior (4) and forming a heat-exchange channel (5). The converter (1) can be operated in such a way that a gaseous heat flow circuit (6) is established within the first interior (3) and flows in through a first inlet opening (15) of the heat-exchange channel (5) and flows out through a first outlet opening (16) of the heat-exchange channel (5), the second interior (4) forming a cooling channel (7). The converter (7) can be operated in such a way that a gaseous cooling flow (8) flowing through the cooling channel (7) is established and flows around the heat-exchange channel (5), the cooling channel (7) being arranged in a region of overlap with the heat-exchanger channel (5) in such a way that a first flow direction (9) of the gaseous heat flow circuit (6) runs substantially perpendicularly or parallel to a second flow direction (10) of the gaseous cooling flow (8).

Description

technical field [0001] The invention relates to a converter comprising a converter housing having a first inner space and a second inner space, wherein the first inner space is arranged separately from the second inner space and The first heat loss generated in the first interior space during operation of the convector can be dissipated at least partially into the second interior space, and the first interior space is thereby at least partially dissipated. Background technique [0002] In drive technology, electrical or electronic components such as converters are frequently exposed to aggressive environmental influences during operation, such as splashing water or dust, which can have a negative impact on the availability or service life of the components if protective measures are neglected Negative impact. [0003] As the simplest measure for protecting the converter and its electronic components such as control units and regulation units from damage due to the above-men...
