20130008633 | COOLING APPARATUS FOR COOLING A POWER ELECTRONIC DEVICE - Exemplary embodiments are directed to a cooling apparatus for cooling a power electronic device, the apparatus including at least one panel that is adapted to be thermally connected to a heat source in order to receive heat from the heat source. The panel is also adapted to be thermally in contact with an air flow in order to transfer heat from the panel. The panel includes at least one hole between a first side of the panel and a second side of the panel. The hole is adapted to attenuate a vibrating air pressure generated by an acoustic noise source and carried by the air. | 01-10-2013 |

20130258594 | HEAT EXCHANGER FOR TRACTION CONVERTERS - A heat exchanger including a first heat exchanger module with a first evaporator channel and a first condenser channel. The first evaporator channel and the first condenser channel are arranged in a first conduit. The first evaporator channel and the first condenser channel are fluidly connected to one another by a first upper distribution manifold and a first lower distribution manifold such that the first evaporator channel and the first condenser channel form a first loop for a working fluid. The first heat exchanger module includes a first evaporator heat transfer element and a first condenser heat transfer element. The heat exchanger includes a second heat exchanger module coupled to the first heat exchanger module by a fluid connection element for an exchange of the working fluid between the first heat exchanger module and second heat exchanger module. | 10-03-2013 |
20130340978 | TWO-PHASE COOLING SYSTEM FOR ELECTRONIC COMPONENTS - A two-phase heat exchanger for cooling at least one electronic and/or electric component includes an evaporator and a condenser. The evaporator transfers heat from the electronic and/or electric component to a working fluid. The condenser includes a roll-bonded panel, which has a first channel which has a first connection port and a second connection port. The evaporator has a second channel and first connection openings and second connection openings. The first connection port of the first channel is connected to one first connection opening of the evaporator and the second connection port of the first channel is connected to one second connection opening of the evaporator and the working fluid is provided to convey heat by convection from the evaporator to the condenser by flowing from the second channel through the first connection opening or the second connection opening of the evaporator towards the first channel. | 12-26-2013 |
20140071629 | COOLING CIRCUIT WITH A SUFFICIENTLY ACCURATELY MEASURED HEAT EXCHANGER - An exemplary power electronics module includes a first power electronics element that generates a first heat flow during operation of the power electronics module, a second power electronics element that generates a second heat flow during operation of the power electronics module. The first cooler is in thermal contact with the first power electronics element to receive at least part of the first heat flow. The second cooler is in thermal contact with the second power electronics element to receive at least part of the second heat flow. A heat exchanger is configured to transmit at least part of the first heat flow and the second heat flow to a primary cooling flow and transfer heat flow in a thermally efficient manner. A magnitude of the heat flow is less than a total magnitude that is formed from a maximum first heat flow and a maximum second heat flow. | 03-13-2014 |
20150136358 | COOLING ELEMENT - A cooling element includes a first surface for receiving an electric component, and a second surface which is provided with fins for forwarding a heat load received from the electric component via the first surface to surroundings. One or more of the fins are provided with a respective flow channel for passing a fluid within each respective fin, to provide efficient cooling. | 05-21-2015 |
