Abstract: A heat dissipation device includes a heat dissipation member, a heat transfer member, and a reinforcing member. The heat transfer member has one side attached to the heat dissipation member, and two opposite lateral edges thereof are respectively provided with at least one connection portion and at least one through hole. The reinforcing member is connected to the other side of the heat transfer member, and two opposite lateral edges thereof are respectively formed with at least one mating connection portion for correspondingly connecting to the connection portion. The reinforcing member is provided at a central portion with an opening. With these arrangements, the heat transfer member can bear a larger locking force when the heat dissipation member is locked thereto, and is also prevented from deformation.

Abstract: An assembling structure of heat dissipation device is applied to a circuit board. A heat generation unit is disposed on one side of the circuit board. The assembling structure of the heat dissipation device includes a heat dissipation unit, at least one latch member and at least one retainer member. The heat dissipation unit is attached to one side of the heat generation unit, which side is distal from the circuit board. At least one latch section outward extends from an edge of the heat dissipation unit. The latch member is fixedly disposed on the circuit board and formed with at least one opening and at least one perforation. The latch section is correspondingly latched in the opening. An elastic member is fitted on the retainer member. The retainer member correspondingly passes through the perforation to fix the latch member on the circuit board.
