    Abstract: A vapor chamber for cooling a heat source is provided. The vapor chamber includes a cavity between a baseplate and a condenser wall, the cavity containing a cooling medium, wherein the baseplate has an evaporator side towards the cavity and an attachment side opposite to the evaporator side for attaching the heat source, wherein the baseplate is adapted for transferring heat from the attachment side to the cavity, such that cooling medium evaporates at the evaporator side and condenses at the condenser wall, and wherein the vapor chamber further includes a channel, which is at least partially connected to the baseplate, with an inlet below a liquid level of the cooling medium and an outlet above the liquid level and which provides a bubble pump for transporting the liquid medium from the inlet to the outlet.

    Abstract: The invention relates to a two-phase heat transfer device for dissipating heat from a heat source, for instance a power semiconductor module, by a heat transfer medium, wherein the two-phase heat transfer device includes a main body, wherein the main body is formed by a body material and includes a multi-dimensional void network, wherein the multi-dimensional void network includes voids and is adapted for containing the heat transfer medium, wherein the multi-dimensional void network is adapted such that a flow of the heat transfer medium along a path through the main body is based on a variation in capillary action exerted by the multi-dimensional void network on the heat transfer medium along the path. Further the invention relates to a power semiconductor module comprising the above two-phase heat transfer device for heat dissipation and to a method for producing the above two-phase heat transfer device.
