Radiator with airflow guiding structure
A radiator includes a heat transfer base ( 30 ), a heat dissipation member ( 20 ) secured to the heat transfer base and a fan ( 50 ) mounted to the heat dissipation member. The heat dissipation member comprises a plurality of fins ( 22 ) for dissipation heat. Air guide structures are formed between the fins for guiding air from the fan to a middle portion of the heat transfer base and a middle bottom portion of the heat dissipation member in order to enhance heat dissipating efficiency of the radiator.
1. A radiator comprising:
a heat dissipation member comprising a plurality of fins extending from one end to an opposite end of the heat dissipation member, air guide structures directed to a middle portion of said one end being formed between the fins and between said ends;
a fan mounted on the heat dissipation member at said opposite end, and
a rectangular heat transfer base to which the heat dissipation member is attached;
wherein the heat dissipation member comprises a pair of fin sub-assemblies juxtapose to each other, and
wherein the heat transfer base comprises a pair of parallel engaging plates interposed between said fin sub-assemblies.
2. The radiator of claim 1 , wherein the air guide structures are a plurality of elongated protrusions stamped from the fins.
3. The radiator of claim 1 , wherein the air guide structure comprise a plurality of elongated tabs bent from the fins.
4. The radiator of claim 1 , wherein a channel is defined between the engaging plates.
5. A radiator comprising:
a heat transfer base;
a fan; and
a plurality of fins extending between the heat transfer base and the fan, a plurality of air guide structures being formed between the fins for directing air from the fan to a middle portion of the heat transfer base,
wherein the heat transfer base has a pair of engaging plates between the fins, and a channel is defined between the engaging plates.
6. The radiator of claim 5 , wherein the fan is mounted to the fins via a pair of fan holders.
7. The radiator of claim 5 , wherein each of the fins forms a rim contacting a top surface of the heat transfer base.
8. The radiator of claim 5 , wherein each of the fins forms a flange contacting an outer surface of the engaging plates.
9. A radiator comprising:
a heat dissipation member comprising a plurality of fins, at least one of the fins defining opposite side edges;
a rim being formed at said fin adjacent one of said opposite side edges;
a guide structure being formed at the fin adjacent the other of said opposite side edges and directed to the rim, and
a heat transfer base, the rim contacting the heat transfer base,
wherein the heat transfer base comprises an engaging plate, a flange being formed at said one of said opposite side edges and contacting the engaging plate.
10. The radiator of claim 9 , wherein the heat dissipation member comprises a pair of fin sub-assemblies juxtaposed to each other, and the heat transfer base further comprises another engaging plate the engaging plates being interposed between said fin sub-assemblies.
11. The radiator of claim 9 , wherein the guide structure comprises elongated tab and protrusion aligned with each other and extending from said fin.
