Heat dissipation device with a heat pipe

A heat dissipation device comprising:

• at least two heat pipes each comprising a flattened evaporating portion and a condensing portion, the evaporating portions closely connected with each other;
• a plurality of fins thermally connected with the heat pipes and having a bottom surface defining a middle protrusion and a pair of receiving spaces at flanks of the middle protrusion, the condensing portions of the heat pipes extending through the fins;
• and
• two locking members located at two lateral sides of the evaporating portions of the heat pipes, respectively, each of the locking members having a locking beam which is received in a corresponding receiving space and soldered to the bottom surface of the fins and juxtaposed to a corresponding lateral side of the evaporating portions of the heat pipes and two legs extending outwardly from opposite ends of the locking beam at an angle to the locking beam;
• wherein a flat bottom surface of the evaporating portions of the heat pipes is adapted for directly engaging with an electronic component;
• wherein the fins each form a flange perpendicularly extending from a bottom edge thereof;
• and
• wherein the flanges of the fins form a planar surface at a bottom of the middle protrusion of the fins for contacting with the evaporating portions of the heat pipes;
• wherein the evaporating portions of the heat pipes are wholly located at an underside of the planar surface formed by the flanges of the fins and have a flat top surface directly attached to the planar surface formed by the flanges of the fins.
