Abstract

A heat-radiating structure co-usable with heat-radiating window of a housing of an electronic appliance, including a housing having a rigid wall defining an interior space. At least one side of the rigid wall is formed with an opening or a heat-radiating window and multiple fin units each having a free end and a connecting end connecting with an adjacent fin unit. The fin units are serially arranged to form a fin construction. The adjacent fin units define a pitch or exhaustion gap meeting the safety standard regulated by IEC. The heat-radiating structure further has a fan unit having a connecting section connected with the connecting ends of the fin construction. The fan unit is formed with a flow way for conducting the heat generated in the housing toward the fin construction and dissipated out from the opening or heat-radiating window through the pitch or exhaustion gap.

Claims

1. A heat-radiating structure co-usable with a heat-radiating window of a housing of an electronic appliance, comprising:

a housing having a rigid wall defining an interior space, at least one side of the rigid wall being formed with an opening or a heat-radiating window; and

multiple fin units each having a free end and a connecting end connecting with an adjacent fin unit, wherein the fin units form a series of fin constructions arranged at intervals, the adjacent fin units defining a pitch or exhaustion gap under one millimeter, the heat generated in the housing being conducted through the pitch or exhaustion gap and dissipated out from the opening, said fin units extending to said opening or heat-radiating window so that said one millimeter pitch or exhaustion gap prevents alien articles from dropping into the housing through the opening or heat-radiating window.

2. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claim 1, wherein the connecting end of the fin unit has a bridge section extending in a direction transverse or normal to the axis of the fin unit, whereby the fin units form a series of fin constructions arranged at equal intervals to define the pitch or exhaustion gap.

3. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claim 1, wherein the fin construction includes two bridge base sections on two sides for mounting the fin construction in a connecting section of a fan unit.

4. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claim 1, wherein the free ends of the fin units or fin constructions are positioned without exceeding an outer face of the opening or heat-radiating window.

5. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claim 1, wherein the free ends of the fin units or fin constructions are flush with an inner face of the opening or heat-radiating window.

6. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claim 1, wherein the fin unit is made of metal material.

7. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claim 1, wherein the bottoms of the fin units are connected.

8. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claims 1 to 7, further comprising a fan unit having a connecting section at a front of the fan unit for connecting with the connecting ends of the fin constructions.

9. The heat-radiating structure co-usable with heat-radiating window of the housing of the electronic appliance as claimed in claim 6, wherein the fin unit is made of aluminum.
