Abstract
The present application provides a heat sink, including: a heat dissipation plate and at least one heat dissipation tube, the heat dissipation tube further including a first tube section. The bent part and a second tube section, with the first tube section of the heat dissipation tube is at least partially embedded in the heat dissipation plate and the second tube section is arranged outside the heat dissipation plate. The first tube section and the second tube section are parallel to each other and connected via the bent part. The heat dissipation tube is provided with at least one cooling fin extending outwards from an outer wall of the heat dissipation tube. In addition, a frequency converter employs the heat sink in an embodiment. The heat sink of at least one embodiment has high heat dissipation efficiency and a small volume.
