Abstract: The present invention is concerned with a provision of sufficient cooling to converter cells arranged in a compact design. In a stack of converter cells arranged on top of or next to each other, both the power electronics modules and cell capacitors face corresponding components of adjacent converter cells, which requires adequate electric, dielectric, and short-circuit design measures in-between the cells. With increasing footprint requirements, heat-generating components are packed more closely and the space available next to the cell capacitors, specifically between the power electronic modules and the capacitors, becomes scarce. Accordingly, in a compact converter design, circulation of ambient air in a stacking direction may be impeded or reduced to an extent that precludes cooling of the cell capacitors via capacitor surfaces perpendicular to the stacking direction. Here, a cooling system that transfers, via dedicated thermal connections, excess cooling power from forced convection boiling cooling of the power electronic modules to the cell capacitors ensures sufficient cooling of the latter.

Abstract: A method to produce a sinter structure (100), comprises steering an energy beam (110) targeted at a surface of a feedstock (114) of loose metal powder grains (108) over an expanse (106) of the sinter structure (100) to heat near-surface grains (108) inside the expanse (106) to a sintering temperature of the metal and fuse the heated grains (108) to a sintered porous metal material (104), wherein an energy exposure of the grains (108) is limited to a sintering energy density inside the expanse (106).

Abstract translation: 本发明涉及对以紧凑设计布置的转换器单元提供充分冷却。 在布置在彼此顶部或彼此相邻的堆叠的转换器单元中，功率电子模块和单元电容器都面向相邻转换器单元的相应部件，这需要在单元之间的足够的电，电介质和短路设计措施 。 随着占地面积的增加，发热元件的封装更加紧密，单元电容器旁边的可用空间，特别是功率电子模块和电容器之间的空间变得稀缺。 因此，在紧凑的转换器设计中，周围空气在堆叠方向上的循环可能被阻碍或减小到一定程度，从而不能经由垂直于堆叠方向的电容器表面冷却电池电容器。 在此，通过专用热连接将冷却功率从电力电子模块的强制对流沸腾冷却传递到电池电容器确保了后者的充分冷却。
