摘要:
An electronic enclosure comprising a casing, a sealed thermal chamber within the casing housing electronic components. A heat exchanger (4) is mounted in the casing externally of the chanber, with a first duct (2) leading from the thermal chamber to the heat exchanger and a second duct (6) leading from the heat exchanger back to the thermal chamber. A fan (7, 8) forces air from the chamber through the first duct to the heat exchanger and back to the thermal chamber through the second duct. The heat exchanger is an element (4) comprising a thermally conductive tubular member (11) having a plurality of thermally conductive fins (12) extending from its external surface, and a plurality of thermally conductive rods (13) which extend from the internal surface of the tubular member and are circumferentially and axially staggered.

The present invention relates generally to electric power and process heat generation using a modular, compact, transportable, hardened nuclear generator rapidly deployable and retrievable, comprising power conversion and electric generation equipment fully integrated within a single pressure vessel housing a nuclear core. The resulting transportable nuclear generator does not require costly site-preparation, and can be transported fully operational. The transportable nuclear generator requires an emergency evacuation area substantially reduced with respect to other nuclear generators as it may be configured for operation with a melt-proof conductive ceramic core which allows decay heat removal even under total loss of coolant scenarios.

A heat exchanger includes at least one cylindrical tubular member formed from a tubular structure and chamber assemblies. A plurality of flow altering members are coupled at predetermined intervals within the tubular structure. The flow altering members have an angled surface on their respective sides facing the flow of a heat exchange medium. Pairs of inlet orifices and outlet orifices are formed on the wall of the tubular structure at the same intervals as the flow altering members. Chamber assemblies are coupled as a full or partial collar on the exterior of the tubular structure. Each chamber assembly is hollow, permitting fluid flow within, and is in fluid communication with a corresponding inlet orifice, outlet orifice pair so that the heat exchange medium repeatedly flows out of the tubular structure into a chamber assembly and back into the tubular structure. Multiple cylindrical tubular members may be coupled between manifolds.

The invention relates to an air intake tract arrangement (2) for an internal combustion engine with at least one intake passage (4) and at least one charge air cooler (5), wherein the charge air cooler (5) comprises a cooling fin arrangement (8) with at least one cooling fin (9) extending at least partly into the intake passage (4). The charge air cooler (5) comprises at least one cooler casing (10) surrounding a cooling chamber (11), said cooling chamber (11) being separated from the intake passage (4) by a wall section (12), and the cooling fin arrangement (8) comprises a first region (13) extending into the intake passage (4) and a second region (14) extending into the cooling chamber (11), wherein the cooling fin arrangement (8) passes through the wall section (12). This air intake tract arrangement (2) enables improved cooling of the charge air in a simple way.
