Abstract:
1. A Heat transfer device comprising: a first heat conducting body, including a first heat absorbing section, a first heat entry surface, a first heat transfer section and a first support section; a second heat conducting body, including a second heat absorbing section, a second heat entry surface, a second heat transfer section and a second support section; at least one semiconductor component at least partially disposed between first heat conducting body and the second heat conducting body, the at least one semiconductor component comprising one or both of a laser and a light-emitting diode element, the semiconductor component including a first side, a first contact surface on the first side, a second side opposite the first side, and a second contact surface on the second side, wherein at least a portion of the first contact surface is substantially flat and at least a portion of the second contact surface is substantially flat, wherein at least a section of the first heat entry surface is arranged opposite the first contact surface in a direction facing away from the semiconductor component, wherein a first joining zone is located between the first heat entry surface and the first contact surface, the first joining zone having a thickness oriented perpendicular to the first contact surface and extending from the first contact surface to the first heat entry surface, wherein the first heat transfer section at least partially extends beyond the semiconductor component in a first heat transfer direction parallel to the first contact surface, wherein at least a section of the second heat entry surface is arranged opposite the second contact surface in a direction facing away from the semiconductor component, wherein a second joining zone is located between the second heat entry surface and the second contact surface, the second joining zone having a thickness oriented perpendicular to the second contact surface and extending from the second contact surface to the second heat entry surface, wherein the second heat transfer section at least partially extends beyond the semiconductor component in a second heat transfer direction parallel to the second contact surface, wherein at least a portion of the second heat transfer section lies opposite at least a portion of the first heat transfer section, wherein the first heat transfer section is thermally connected to the second heat transfer section via a joining gap defining a third joining zone, the third joining zone having a thickness defined between the first contact surface to the second contact surface and oriented perpendicular to the second contact surface, wherein the first support section is adjacent the first heat transfer section and the second support section is adjacent the second heat transfer section, wherein at least a portion of the first support section lies opposite at least a portion of the second support section, the respective portions of the first support section and second support section arranged opposite each other being separated by a spacer, and wherein at least in a section of the third joining zone the thickness of the third joining zone is thicker than the thickness of at least one of the first joining zone and the second joining zone.
