Heat-dissipation device having dust-disposal mechanism

Abstract

A heat-dissipation device having a dust-disposal mechanism for removing dust from cooling metallic fins is provided, which includes a heat-conducting module and a dust-disposal mechanism. The heat-conducting module has a plurality of metallic fins arranged in the same direction and apart with a gap formed therebetween. The dust-disposal mechanism has a cleaning unit corresponding to the metallic fins so as to insert into the gap between the metallic fins and clear or absorb the dust accumulated on the metallic fins, thereby enhancing the cooling efficiency of the heat-conducting module.

1 . A heat-dissipation device having a dust-disposal mechanism, comprising:
 a heat-conducting module, comprising a plurality of metallic fins arranged in parallel and apart with a gap formed therebetween; and   a dust-disposal mechanism, comprising a cleaning unit inserting to the gap formed between the metallic fins.   
   
   
       2 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 1 , wherein the dust-disposal mechanism further comprises a handle connected to the cleaning unit. 
   
   
       3 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 2 , wherein a pivoting portion is disposed at one end of the handle connected to the cleaning unit. 
   
   
       4 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 1 , wherein the cleaning unit comprises a brushhead formed by a plurality of soft wipers arranged. 
   
   
       5 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 4 , wherein the material of the soft wipers comprises fiber, cotton, or nylon. 
   
   
       6 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 1 , wherein the cleaning unit comprises a brushhead formed by a plurality of soft bristles arranged. 
   
   
       7 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 6 , wherein the material of the soft bristles comprises fiber, cotton, or nylon. 
   
   
       8 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 1 , wherein the dust-disposal mechanism further comprises an actuator connected to the cleaning unit for providing a vibration source for the metallic fins. 
   
   
       9 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 1 , wherein the heat-conducting module further comprises at least one heat pipe with one end connected to the metallic fins and the other end connected to a heat source. 
   
   
       10 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 1 , further comprising a fan module having an air outlet corresponding to the metallic fins. 
   
   
       11 . The heat-dissipation device having a dust-disposal mechanism as claimed in  claim 10 , wherein an accommodating slot is formed between the fan module and the metallic fins so as to accommodate the cleaning unit.
