Embodiment Construction
[0053] figure 1A simplified schematic diagram of a power module comprising a two-phase heat exchanger 1 according to an exemplary embodiment of the invention is shown. The heat exchanger 1 including the evaporator body 200 and the condenser body 100 serves to cool at least one of electronic and electrical components 300 . The condenser body includes a plurality of roll bonded panels 110 . These roll bonded panels 110 are made of aluminum sheet metal and are thermally and mechanically permanently attached to the evaporator body 200 so that the heat exchanger 1 has a honeycomb overall appearance when viewed in cross section, Such as the traditional fin radiator. The roll-bonded panels 110 of the condenser 100 and the evaporator 200 are connected or joined by CAB (Controlled Atmosphere Brazing) or flame brazing. Alternatively, the joining of the roll-bonded panels and the evaporator may be performed by any other feasible and suitable means, such as an adhesive, eg epoxy.

The invention relates to a two-phase cooling system for electronic components. A two-phase heat exchanger for cooling at least one electronic and / or electric component with an evaporator and a condenser is provided. The evaporator is adapted to transfer heat from the electronic and / or electric component to a working fluid. The condenser comprises 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 in order to convey heat by means of 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.
Description
technical field [0001] The present invention relates to cooling of electronic and electrical components. In particular, the invention relates to a two-phase heat exchanger comprising an evaporator and a condenser for cooling at least one electronic and / or electrical component, to a power module with an electronic and / or electrical component and a two-phase heat exchanger, It also relates to the use in a vehicle of a power module having such a heat exchanger for cooling electrical and / or electronic components. Background technique [0002] In the field of electrical and electronic devices, efficient cooling systems are used to absorb the heat generated by ohmic losses and switching losses of electrical and / or electronic components and to transmit the heat in order to prevent these electrical or electronic components from overheating and damage or even fail. Although electrical and electronic devices including so-called power electronic components, such as power converters, ...
