Abstract

A heat exchanger radiating fin structure and a heat exchanger thereof. The radiating fin includes a main body and at least one rib. The main body has a first plane face and at least one lateral side. Multiple depressions are formed on the first plane face. The rib is disposed on a portion of the first plane face, which portion is free from any of the depressions. The rib obliquely extends in a direction neither normal nor parallel to any lateral side of the first plane face. The heat exchanger includes a radiating fin assembly composed of multiple piled up radiating fins. Each two adjacent radiating fins define therebetween a flow way having at least one inlet and at least one outlet. With the depressions and the rib, the structural strength of the radiating fin is increased and the heat exchange performance of the heat exchanger is enhanced.

Claims

1. A heat exchanger radiating fin structure comprising:

a main body having a first plane face and at least one lateral side, multiple depressions being formed on the first plane face; and

at least one rib disposed on a portion of the first plane face, which portion is free from any of the depressions, the rib obliquely extending in a direction neither normal nor parallel to any lateral side of the first plane face.

2. The heat exchanger radiating fin structure as claimed in claim 1, wherein the main body further has a second plane face opposite to the first plane face, the depressions being recessed from the first plane face to the second plane face.

3. The heat exchanger radiating fin structure as claimed in claim 2, wherein those portions of the second plane face that are behind the depressions are plane.

4. The heat exchanger radiating fin structure as claimed in claim 2, wherein multiple bosses corresponding to the depressions are formed on those portions of the second plane face that are behind the depressions.

5. The heat exchanger radiating fin structure as claimed in claim 2, wherein the rib protrudes from the first plane face.

6. A heat exchanger comprising:

a radiating fin assembly composed of multiple radiating fins arranged at intervals in parallel to each other, each two adjacent radiating fins defining therebetween a flow way, the flow way having a first inlet, a second inlet, a first outlet and a second outlet on four sides of the radiating fin assembly respectively, the first inlet being opposite to the first outlet, while the second inlet being opposite to the second outlet, each radiating fin having a main body, the main body having a first plane face and at least one lateral side, multiple depressions being formed on the first plane face, each radiating fin further having at least one rib disposed on a portion of the first plane face, which portion is free from any of the depressions, the rib obliquely extending in a direction neither normal nor parallel to any lateral side of the first plane face.

7. The heat exchanger as claimed in claim 6, wherein the main body further has a second plane face opposite to the first plane face, the depressions being recessed from the first plane face to the second plane face.

8. The heat exchanger as claimed in claim 7, wherein those portions of the second plane face that are behind the depressions are plane.

9. The heat exchanger as claimed in claim 7, wherein multiple bosses corresponding to the depressions are formed on those portions of the second plane face that are behind the depressions.
