Abstract:
A thermal dissipation structure suitable for use with a first housing member and a second housing member to be assembled with each other, the thermal dissipation structure comprising:a first assembly structure formed on the first housing member, wherein the first assembly structure includes a first shoulder structure having a first contact surface, and a plurality of first slots that are further recessed from the first contact surface of the first shoulder structure; and a second assembly structure formed on the second housing member, wherein the second assembly structure includes a second shoulder structure having a second contact surface, wherein the first housing member and the second housing member are assembled to each other by engaging the first assembly structure and the second assembly structure into each other so that the first contact surface and the second contact surface abut against each other to form a contact interface between the first and second housing members, wherein an edge of the first assembly structure does not abut against the second contact surface of the second assembly structure thereby forming a first clearance, wherein a plurality of second clearances are formed between the first slots and the second contact surface of the second assembly structure, wherein through the first clearance and the second clearances between the first slots and the second contact surface, a plurality of ventilation passageways that communicate with an interior and an exterior of the first and second housing members are formed along the contact interface to dissipate heat.
