Abstract (en)
The present invention provides a heat dissipation device, which comprises: a base (10); plural heat dissipation pipes (20), wherein each heat dissipation pipe (20) is hollow and formed in an L-like shape, one end thereof passes the base (10), the other end thereof is received at the bottom of the base; and a heat dissipation plate (30) having a main body (31), the center of the main body (31) is formed with a chamber (32) having its outer periphery formed with plural heat dissipation grooves (33), the outer side of the main body is formed with plural wavelike shaped heat dissipation fins (34). With the aforementioned structure, advantages of smaller in volume, lighter in weight and more efficient in heat dissipation can be achieved.
