Heat sink and converter comprising same

A converter module comprising:

• a printed circuit board on which a plurality of components performing voltage conversion are mounted;
• a heat sink that serves as a contact surface in contact with an external device when the converter module is mounted on the external device and radiates heat generated in the component;
• and
• a housing covering outside of the converter module,
• wherein the heat sink comprises:
• a main heat sink;
• a heat pipe mounted in a groove formed on one surface of the main heat sink;
• a heat dissipation member formed at an upper portion of the heat pipe to transfer heat generated in the component to the heat pipe;
• and
• an elastic member mounted in a space formed inside the heat dissipation member to apply pressure to the main heat sink, and
• wherein the main heat sink is in contact with a contact surface of the external device to which the converter module is mounted by the pressure applied from the elastic member.
