Product Description
Designed for continuous thermal load in industrial electronics.
This aluminum heat sink is designed to efficiently dissipate heat generated by high-power electronic devices, ensuring stable operation and extended service life of equipment. It is widely used in welding machines, audio amplifiers, air conditioners, inverters, and other industrial or electrical systems. With excellent thermal conductivity and reliable structural design, it provides effective cooling performance under continuous and high-load working conditions.
Please confirm the heat sink drawing, profile size, cutting length, hole positions, surface treatment, logo requirements, order quantity, and packaging requirements before quotation.

Thermal resistance vs airflowG-5423
Thermal Benchmark
Confirm final performance with your airflow, load, and assembly space.
The drawing profile is the quotation baseline. Final thermal behavior depends on air velocity, component contact quality, mounting pressure, ambient temperature, and enclosure layout.
Use the CAD drawing to verify fin clearance and mounting area.Share heat load, airflow direction, and duty cycle for engineering review.
Features
Thermal performance, machining options, and buyer-side confirmation points.
Made of high quality aluminum with good thermal conductivity.Reduces the risk of hardware failure caused by overheating.Maximizes the surface area in contact with cooling air.The 10 pcs fins increase the heat sink contact area and help provide greater heat transfer.Designed for welding machines, inverters, computers, power transistors, FETs, ICs, power amplifiers, voltage regulators, MOSFETs, SCRs, and other electronic devices.Please confirm that the heat sink size and drawing match your application requirements before ordering.

Transportation & Storage
Protect surface quality before assembly or shipment transfer.
Handle with care during transportation to avoid collision, extrusion, or surface damage.Store in a dry and ventilated environment. Avoid moisture, corrosive substances, and prolonged exposure to high temperatures.Keep the product in its original packaging before use to maintain surface quality and prevent oxidation.
Production path
From drawing review to protected export packing.
Confirm technical details
We review dimensions, machining, logo, packaging, sample needs, and shipping conditions before quote.
Sample and production
Samples can be arranged before mass production, then cutting, drilling, tapping, finishing, and inspection move together.
Pack and ship
Cartons are prepared to reduce collision, extrusion, oxidation, moisture, and surface damage during transport.
