How to custom pin fin heat sink ?

1. Determine the specification requirements of the heat sink.

Before customizing the pin-fin heat sink, we need to clarify the requirements for the size, material, heat dissipation efficiency and other aspects of the heat sink. These specifications are often based on specific equipment or systems, so it is necessary to fully consider the actual application requirements and conditions

2. Select appropriate materials.

According to the specification requirements of the heat sink, we need to select appropriate materials to ensure the quality and effect of the heat sink. Commonly used heat sink materials include aluminum alloy, copper alloy, stainless steel, etc. They have different thermal conductivity, density, corrosion resistance and other characteristics. It is necessary to select the most suitable material through experiments and calculations

3.Design and processing.

After the specification requirements and material selection of the heat sink are determined, we need to design and process the heat sink. In the design process, it is necessary to fully consider the structure of the fins, heat removal area, number of fins, fin spacing and other factors. In the processing process, the commonly used methods include CNC machine tools, laser cutting and other technologies

4. Pin-fin heat sink test.

The customized pin-fin heat sink needs to be tested several times to confirm its heat dissipation effect and quality. The test methods include air cooling, water cooling and other methods. The actual effect of the heat sink is verified by monitoring the temperature, flow and other parameters.

5. Mass production and delivery.

After confirming the quality of the heat sink through the test, we need to make it in batch and deliver it according to the agreed delivery date.

Custom pin fin heat sink structural design

The structural design of pin-fin heatsinks needs to consider the following aspects:

1. Area and thickness of heat sink: calculate the required area and thickness of heat sink according to the actual application scenario.

2. Number and structure of fins: the number and structure of fins have a great impact on its heat dissipation performance, which needs to be designed and optimized according to the specific situation.

3. Layout of heat sink: the layout of heat sink is also one of the factors that affect the heat dissipation performance, which needs to be analyzed and designed according to the specific situation.

The above are the main aspects to be considered in the structural design of pin-fin heat sinks.

Pin Fin Heat Sink:The Ultimate Guide

A pin-fin heat sink refers to a heat sink design that uses a series of small fins or pins to increase the surface area for heat dissipation. This design is often used to manage the heat generated by electronic components such as CPUs to prevent overheating and damage. The pins are usually made of materials with high thermal conductivity, such as aluminum or copper, and can be arranged in various configurations to optimize performance. Pin-fin heat sinks are popular for their compact size and efficient heat transfer capabilities, making them ideal for use in small or densely packed electronic devices.

Pin fin heat sink sometimes also called by customers as pin fin heatsink , pin fin heat sinks, pin-fin heat sink or pin heatsink, pin heat sink,  etc, usually they express the same product.

Pin Fin Heat Sink Material

The most common pin fin heat sink is aluminum pin fin heat sink and copper pin fin heat sink.

1. Aluminum pin fin heatsink show perfect performance because the material is relatively light, In addition, it provides better and more even heat dissipation than pin fin heat sinks made of other materials. Aluminum rarely requires plating because it guarantees optimal corrosion resistance to coolant, Thus, this material provides a cost-effective option for the manufacture of pin fin heatsinks

2. Copper pin fin heat sink shows higher level of thermal conductivity than aluminum. This excellent thermal conductivity enables copper to easily absorb power peaks. In most cases, it comes with a thin metal coating that effectively prevents corrosion, It is the most suitable material choice for relatively high-end applications, because copper is more expensive than aluminum

Pin Fin Heat Sink Advantages

1. Pin fin heat sink have a great thermal performance when the ambient airflow is limited, it allows the airflow can pass through the heat sink from any direction

2. Pin fin heat sink provide low thermal resistance at low airflow rate, it's the extraordinary thermal option for natural convection, instable airflow circumtances.

3. Pin fin heat sink has low pressure drop property, due to the pin fin construction, the low pressure drop can improve the thermal transferring ability.

4. The cold forging and extrusion process make the heat sink as a solid structure ,there is no connection joint between the fins and base, so no thermal resistance between the fins and base, then the heat can be transferred to the fins quickly and dissipated rapidly.

Factors Affecting The Pin Fin Heat Sink Efficiency

There are many factors that determine the overall performance of a pin fin heatsink, here are the common elements you must consider to start design a pin fin heat sink:

1. Material

In general, aluminum and copper are the main materials used in the manufacture of high efficiency pin fin heat sinks,but different alloys with different thermal conductivity, so need according to the specific project to choose different aluminum alloy series

2. Pin Fin array design

Pin fin heat sinks normally the pins can be oval, square, or round, different shape and array from the base, has a huge impact on the overall performance of the heat sinks.

3. Surface treatment

Surface treatment of the heat sink also will impact the thermal conductivity of the heatsinks, heat sink with a matte black surface is more effective than a shiny bare metal heat sink. Technically, gloss surface finish has a low effective emissivity due to its low surface area.

4. Size of the heat sinks

The overall efficiency of a pin fin heat sink is hugely determined by its size, Larger size tend to be more efficient than smaller ones

Pin Fin Heat Sink Applications

Pin fin heat sinks widely used in various devices, such as below:


Control processing units


Medical equipments

IC cooling


Automobile radiators


Telecommunication equipment

Industrial components and equipment

Lighting lamps

Refrigerator condensers

Here take an example of pin fin heat sink for igbt market

In the IGBT market, pin fin heat sink is an important heat sink material mainly used for heat dissipation of IGBT modules. IGBT is a high-performance semiconductor transistor widely used in fields such as power electronics, rail transit, and new energy.
As the power density of IGBT modules continues to increase, their heat will also become more concentrated, making heat dissipation more important. The pin-fin heat sink has unique heat dissipation performance, which can achieve faster and more efficient heat dissipation, thereby ensuring the stable operation and lifespan of IGBT modules.
In addition, with the development of the new energy vehicle industry, the application of pin fin heat sinks in IGBT will also continue to improve. The IGBT module is an indispensable part of the motor control system used in new energy vehicles, and its heat dissipation effect directly affects the performance and stability of the entire system. Therefore, the application prospects of pin heatsink in the field of new energy vehicles are very broad.
Overall, with the continuous development and growth of the IGBT market, as an important supporting material, the market demand for pin fin heatsinks will gradually increase and is expected to maintain a sustained growth trend.
