Kingka - Your Trusted Custom Heatsink Manufacturing Partner

The function of the heat sink is to transfer the heat generated by the machinery or other appliances in the working process in time to avoid affecting its normal work of the device or instrument.According to the heat dissipation method, the common heat sink can be divided into air cooling, heat pipe heat sink, liquid cooling, semiconductor refrigeration, compressor refrigeration and other types.

Depending on the shapes and materials, heat sink can be made by many manufacturing methods.

The most common and cost effective methods include extrusion, forging, casting and stamping. Other methods to produce higher performing heat sinks include CNC machining, skiving and swaging.Although they are more expensive, they can produce high efficient and compact heat sinks with features that cannot be done by other methods.

The heat sink is made of lightweight, strong thermal conductivity and strong plasticity. Aluminum alloy is the most popular heat sink manufacturing material on the market. It has relatively lightweight, good heat dissipation performance, convenient processing, and low price. Copper is difficult to react with oxygen and water in the air at room temperature, so there is no need to perform complex post-processing on the copper radiator. Copper heat sink has fast heat dissipation, high thermal conductivity, thermal corrosion resistance and long service life .

Types of Custom Heat Sink

Brazing Heat Sink

Brazing joins metals like aluminum plates using a lower melting point filler metal. This high-end method produces strong joints without corrosive residue. Vacuum brazing offers uniform heating, precise temperature control, no post-cleaning, and process repeatability.

Cold Forged Heat Sink

Cold forging, a cold working method, shapes aluminum in a closed die through press squeezing, known as cold heading. This process yields high-performance heat sinks due to increased surface area enhancing thermal performance. Straight fins, formed under high pressure, optimize airflow in various directions, advantageous for specific applications.

Heat Pipe Thermal Module

Heat Pipe Thermal Modules find wide applications in CPUs, LEDs, electronics, and power systems. Custom-designed heat sinks are crucial to optimize performance and reliability due to varying temperatures and environments. Our engineers employ advanced 3D modeling, ANSYS-based thermal analysis, and mechanical support to ensure cost-effective solutions and validate designs in our fully equipped lab.

Extrusion Heat Sink

Extrusion Heat Sink, also called extruded aluminum heat sink, features attractive appearance, lightweight design, and efficient heat dissipation, achieving energy savings. This technology involves heating aluminum ingots to 520-540°C, then forcing the liquid aluminum through a grooved mold under high pressure to create the material. After cutting, the familiar aluminum heat sink is produced.

Friction Stir Welded Heat Sink

Friction stir welding, a popular trend, achieves solid-state welding through pressure-induced frictional heat and plastic deformation. This process, conducted on a high-speed CNC machine, combines machining and welding. Frictional heat is generated by the wear-resistant welding tool, ensuring temperatures remain below melting point for effective welding.

Skived Fin Heat Sink

Skived Fin Heat Sinks, made of aluminum or copper, offer seamless, high-performance cooling with no thermal barriers. They achieve superior cooling with dense fins, surpassing extrusion methods. Skiving creates thin fins, maximizing surface area for efficient heat transfer. Our machines handle fin thicknesses from 50µm to 3mm, ideal for prototyping and cost-effective production.

Epoxy Bonding Heat Sink

Epoxy Bonded Heat Sinks suit high-power use with low thermal resistance. Forced air cooling recommended.

Features:

1.Superior aspect ratio to thin fin extrusions

2.RoHS compliant, high thermal conductivity epoxy or soldered fins

3.Thin as 0.008", height up to 2"

4.Strong mechanical bond 5.Ideal for large heat sinks

Custom Heat Sink Design Process

Kingka is one of the leading custom heat sink manufacturer in China, we can provide one-stop thermal solution service around the world, with our advanced thermal technology, reliable manufacturing process and excellent quality system.

Factors that affect the design of the radiator, such as :

space, operating temperature, air flow rate, ambient temperature, thermal interface, power supply, connection method, estimated use time and so on.

Length of Fin

The longer for the fin, the heat dissipation area is larger, and the better of the heat dissipation effect under normal circumstances . The longer for the fin, the greater for the wind resistance, and the more space occupied, but need to consider the space allocation with the fan.

Material

Aluminum and copper are commonly used. Aluminum is cheap and light; Copper is expensive, heavy and dissipates heat better than aluminum

Heat Pipe

Heat pipe which can be conducive to temperature equalization and reduce the thermal resistance of diffusion. However, the cost increases and the reliability of the radiator decreases.

Depth of fin

The higher for the fin, the heat dissipation area is greater, and the better of the heat dissipation effect under normal circumstances.The higher for the fin, the greater the wind resistance, and the lower of the heat dissipation efficiency of the fin, so we need to consider the space distribution with the fan or the height limit requirements..

Vapor Chamber

Vapor Chamber which is beneficial to equalizing temperature and reducing diffusion thermal resistance, and the effect is better than that of heat pipe.However, the cost is higher than that of the heat pipe, and the reliability of the radiator is lower than that of the heat pipe radiator.
