Abstract:
1. An assembling structure of heat dissipation device, which is applied to a circuit board, a heat generation unit being disposed on one side of the circuit board, the assembling structure of the heat dissipation device comprising: a heat dissipation unit attached to the heat generation unit, at least one latch section outward extending from an edge of the heat dissipation unit; an L-shaped latch member fixedly disposed on each of two opposite sides of the circuit board heat generating unit, each latch member being formed with at least one opening and at least one perforation, one latch section being correspondingly latched in the opening, each latch member having a first latched section and a second latched section connected with the first latched section, a perforation being formed on the first latched section, said opening being formed on the second latched section for the latch section to latch with; at least one retainer member, an elastic member being fitted on the retainer member, the retainer member correspondingly passing through the perforation to fix the latch member on the circuit board; and wherein said heat dissipation unit can be removed by simply biasing said latch members in a direction away from the heat dissipation unit to release said latch sections.
