摘要:
The invention relates to a feedthrough device (10) for an explosion-proof housing which is constructed, in particular, as a "flameproof enclosure" of the flame protection type. The feedthrough device (10) is arranged in a wall opening of the housing and forms a flameproof gap therein. A rigid component (11) is arranged through said gap so as to be displaced in its direction of extension relative to the wall of the housing. The feedthrough device (10) has, in particular, a clamping body unit (20), a sleeve (21), a cap (22) and a thrust collar (23). The sleeve (21) and the cap (22) can be screwed together. Axial forces are transmitted between the clamping body unit (20) and the cap (22) via the thrust collar (23), which axial forces in turn are supported on mutually abutting surfaces (26, 36) of the clamping body unit (20) and/or of the sleeve (21) that run transversally to the longitudinal axis (L). The sleeve (21) thereby exerts a radial clamping force on the clamping body unit (20). The clamping body unit (20) is fully penetrated by a conduit (25) along a longitudinal axis (L), in which conduit a longitudinal section of a component (11) is arranged.

Various apparatuses, methods, and systems are provided for cooling electronic components. For example, an apparatus includes an electronics enclosure having multiple ribs (110, 226, 326, 426) configured to separate electronic components. The apparatus also includes at least one fluid transport structure (208, 308, 408) encased within the electronics enclosure (100, 218, 224). Each fluid transport structure includes multiple pipes (210, 310, 410) and multiple flow channels (212, 412, 502, 504, 506, 510-516, 518, 520, 606, 608). The flow channels are located within the ribs of the electronics enclosure, and the pipes are configured to transport cooling fluid to and from the flow channels.

An emissions cleaning module is provided including a first support, a second support and a mixer module. The mixer module extends between the first support and the second support. The mixer module includes an outer body and an inner body located within the outer body. In addition the outer body is fixedly retained to the first support and the second support. Further, a first end of the inner body is slidingly retained within the outer body, and a second end of the inner body is fixedly retained relative to the outer body at or near the second support.

Emissions cleaning module (1) and associated electronics support unit (180). An emissions cleaning module (1) is provided with an electronics support unit (180) that comprises: • a base member (181) which defines at least one seating location for an electronics module (110a, 110b); and • a roof member 182). The roof member (182) comprises a first end (183) joined to the base member (181) and a second end (185), distal the base member (181), coupled to a brace (70,80) and/or one or more conduits of the emissions cleaning module (1). The roof member (182) may be shaped to extend up and over the base member (181) so as to create an open-mouthed cavity (199) between the base member (181) and the roof member (182) for receiving an electronics module (110 a, 110b) seated at the at least one seating location. The base member (181) may also comprise one or more apertures (120a-120e) creating one or more tortuous thermal paths between the attachment member and the at least one seating location for an electronics module (110 a, 110b).

An emissions cleaning module (1) of a combustion engine may be provided with an inlet module (2) for directing incoming gas flow. It may be desirable to increase the uniformity of gas flow within the emissions cleaning module. An inlet module is described which comprises an inlet (111) for receiving exhaust gases from the combustion engine; an outlet (105) for directing said exhaust gases into an inlet of the emissions cleaning module; and a flow distributor (106) located in a flow path of the exhaust gases between the inlet and the outlet of the inlet module. The flow distributor comprises a plurality of apertures (114) through which, in use, the exhaust gases pass. This may lead to improved uniformity of gas flow within a downstream module.

A portable terminal device (1) according to the present invention includes: a housing (11) comprising a concave portion (21) in which predetermined components are housed, and a mounting surface (22) that is disposed on a top surface of a side wall arranged around the concave portion (21); a fixing component (12) that is fixed to the mounting surface (22) of the housing (11) and comprises a mounting surface (23) and a protruding portion (24) that is arranged around outside of the mounting surface (23); and a display section (13) that is fixed to the mounting surface (23) at an inner side of the protruding portion (24) of the fixing component (12). Further, a rigidity of the fixing component (12) is lower than a rigidity of the housing (11) and the display section (13).
