Heat dissipation device

1. A heat dissipation device comprising:

a heat sink comprising a base and a plurality of fins on the base;

at least one heat pipe comprising a condensating section, the condensating section being secured to the fins and being distant from the base of the heat sink;

a fan holder gripping the condensating section of the at least one heat pipe to retain the fan holder to the heat sink, the fan holder comprising a support plate for supporting the fan and ears perpendicularly extending from opposite sides of the support plate, each of the ears defining an engaging hole therein for engagingly receiving the condensating section of the at least one heat pipe; and

a fan mounted onto the heat sink via the fan holder,

wherein a cutout is defined in each of the ears, the cutout providing a guide way for having the condensating section to enter the engaging hole, the cutout having a width which is smaller than a diameter of the engaging hole.

2. The heat dissipation device of claim 1 , wherein the ears are attached on outmost fins of opposite sides of the heat sink.

3. The heat dissipation device of claim 1 , wherein the support plate of the fan holder is sandwiched between the fins and the fan.

4. The heat dissipation device of claim 3 , wherein the support plate defines a central opening communicating with the fan and the heat sink.

5. The heat dissipation device of claim 1 , wherein the base defines a groove therein, and wherein the at least one heat pipe comprises a vaporizing section received in the groove of the base.

6. A heat dissipation device comprising:

a fin member;

a fan;

a fan holder comprising a support plate which is sandwiched between the fin member and the fan, and ears perpendicularly extending from the support plate; and

at least one heat pipe comprising a condensating section, the condensating section extending across the fin member near the support plate and being gripped by the ears,

wherein each of the ears defines an engaging hole therein for engagingly receiving the condensating section of the at least one heat pipe and a cutout is defined in each of the ears, the cutout providing a guide way for having the condensating section to enter the engaging hole, the cutout having a width which is smaller than a diameter of the engaging hole.

7. The heat dissipation device of claim 6 , wherein the ears grip opposite ends of the condensating section.

8. The heat dissipation device of claim 6 , wherein the ears are spaced from one side of the fin member opposing the fan.

9. A heat dissipation device comprising:

a base attachable to a heat generating component by a contact face thereof to receive heat from said heat generating component, said base having a main face opposing to said contact face and at least one side face neighboring said contact face;

a plurality of fin members extending from said base and a space formed between said main face of said base and plurality of fin members, each of said plurality of fin members having a heat transmittable contact with said at least one side face of said base;

at least one heat-transmittable heat pipe comprising a section attached to said base and another section extending in and through each of said plurality of fin members; and

a fan holder bearing a fan thereon and being attachable to said another section of said at least one heat pipe and spaced from said base, said fan holder comprising a support plate attachable to said plurality of fin members and ears perpendicularly extending from the support plate, said ears gripping said another section of said at least one heat-transmittable heat pipe to retain said fan holder to said plurality of fin members, each of said ears defining an engaging hole engagingly receiving said another section of said at least one heat-transmittable heat pipe.

wherein each of said ears defines a cutout communicating with the engaging hole and said another section of said at least one heat-transmittable heat pipe is engagingly received in the engaging hole after moving through the cutout, the cutout having a width which is smaller than a diameter of the engaging hole.
