    • A two-phase cooling system for cooling power electronic components comprises a condenser section and an evaporator section, each with at least two metal sheets partially bonded together, the at least two metal sheets forming at least one first fluid channel or second fluid channel, respectively being arranged between two bonded areas of the at least two metal sheets. These channels form a continuous, sealed fluid channel, which connects the condenser and evaporator sections. A power electronic element can be arranged on a first main side of the evaporator section within a contact area, and the two-phase cooling system can be pressed against the power electronic component. A support plate is arranged on a second main side of the evaporator section, the second main side being opposite the first main side. The support plate comprises at least one projecting part, which contacts the evaporator section within the at least one bonded area or at least one support element is arranged within the at least one first fluid channel.
    • 用于冷却功率电子部件的两相冷却系统包括冷凝器部分和蒸发器部分,每个部分具有部分地结合在一起的至少两个金属片,所述至少两个金属板分别形成至少一个第一流体通道或第二流体通道 布置在所述至少两个金属片的两个接合区域之间。 这些通道形成连续的密封流体通道,其连接冷凝器和蒸发器部分。 电力电子元件可以在接触区域内布置在蒸发器部分的第一主侧上,并且两相冷却系统可以压靠在电力电子部件上。 支撑板设置在蒸发器部分的第二主侧上,第二主侧与第一主侧相对。 支撑板包括至少一个突出部分,其在至少一个接合区域内接触蒸发器部分,或者至少一个支撑元件布置在至少一个第一流体通道内。
