Heat dissipation device with heat pipes

A heat dissipation device comprising:

• a fin set;
• a first heat pipe comprising separate first and second sections sandwiching the fin set between the first and second sections of the first heat pipe and engaging with the fin set;
• parallel first and second base plates sandwiching the first heat pipe and the fin set between the first and second base plates and engaging with the first heat pipe and the fin set;
• and
• a second heat pipe comprising separate first and second sections sandwiching the first heat pipe, the fin set, the first and second base plates between the first and second sections of the second heat pipe and engaging with the first and second base plates;
• wherein a protrusion extends from the first base plate opposite to the second base plate;
• and
• wherein the protrusion of the first base plate has a groove extending therethrough, and the first section of the second heat pipe is flat and received in the groove and thermally connects with the protrusion.

A heat dissipation device comprising:

• a heat dissipation unit having a base adapted for thermally connecting with a heat generating electronic device and a plurality of fins;
• a first heat pipe having a first evaporating section thermally connecting with the base and a first condensing section thermally connecting with the fins;
• and
• a second heat pipe having a second evaporating section thermally connecting with the base and a second condensing section thermally connecting the fins, wherein the first and second evaporating sections are crisscross.
