A sunflower heat sink is a heat sink designed to be laid out in a radioactive material manner. Generally, extrusion processing is used, and the shapes are round, square or other shapes. It is made into a sunflower shape, which can increase the contact between the heat sink and the air, and the heat spreads to the surroundings of the heat sink through the outside of the center. Its shape allows it to receive cyclones more evenly and smoothly, and to dissipate heat more evenly. This heat dissipation effect is very fast and significant. It is particularly suitable for dissipating heat from today's components. Sunflower heat sinks are widely used in new energy technology, soft starters, power electronics technology, communication equipment and other industries.
Sunflower heat sinks are also divided into several types in terms of finished structure:
Yes, send us the drawing and surface treatment requirements, our engineer will evaluate your drawing and give you a quotation.
Yes, we will not release your design to third party unless with your permission. And we can sign the NDA before you send the drawing.
We will charge the tooling cost, but the tooling cost can be refunded when mass production.
MOQ will be set according to your product and drawing requirements, but generally we will not set MOQ.
We can provide sample production, and the mass production will be carried out after the sample is confirmed to you.
Please rest assured that all our products are QC inspected and accepted with inspection report before delivery and generally there will no non-conformance; in case of non- conformance, please contact us immediately, take some pictures, we will check on the problems and have them reworked or repaired at the first time , the resulting transportation costs borne by our company.
