1. What Is an Industrial Heat Sink?

An industrial heat sink is used to thermally cool industrial electronics and mechanical equipment.

Since industrial equipment usually runs 24/7,

they can produce significant amounts of heat.

Such as:

• Power converters

• Motor drives

• Industrial controllers

• Inverters

• Welding systems

• Automation controls

• Telecommunications equipment

• Solar inverters, etc.

An industrial heat sink helps dissipate heat away from these components.

It typically consists of a thermally conductive base which makes contact with the heat source.

And cooling fins which help dissipate heat into the surrounding air.

Thus, heat will travel from the source to the base and through the fins into the air.

Industrial heat sinks normally need to be more robust and thermally effective.

So manufacturers may use aluminum, copper, heat pipes or create hybrid solutions.

2. How Does an Industrial Heat Sink Work?

Industrial heat sinks use thermal conduction and thermal convection to dissipate heat.

An electronic component will produce heat as it operates.

This heat transfers into the heat sink at the mounting point.

Then, the heat will spread throughout the metal base.

Finally, heat will transfer into the surrounding air via cooling fins.

As a result, three main things determine performance:

• Thermal conductivity

• Heat transfer area

• Airflow

Aluminum offers a good balance of thermal conductivity and weight.

Copper on the other hand has even better thermal conductivity.

So heat sink material is chosen based on thermal requirements.

Industrial equipment can use a fan or blower to force air through the heat sink.

As forced airflow improves heat transfer, forced air heat sinks can dissipate more heat.

3. Why Industrial Equipment Needs Heat Sinks

Industrial equipment often has demanding operating conditions.

Equipment may run for many hours without stopping.

Or they may have to operate in hot/dusty environments.

As a result, thermal management is critical for reliable operation.

A properly selected industrial heat sink can:

• Lower component temperatures

• Improve equipment reliability

• Reduce thermal stress

• Lengthen component lifespan

• Ensure equipment operates efficiently

For instance, industrial inverters can produce a lot of heat.

So you may see a large extruded aluminum heat sink attached to the enclosure.

Motor drives can also require high-performance heat sinks.

As you can see, heat sinks are very important for industrial power electronics.

4. Types of Industrial Heat Sinks

Just as there are many types of electronics, there are many types of heat sinks.

Let’s take a look at some common industrial heat sink designs.

Extruded Aluminum Heat Sink

Heat sink extrusion is one of the most common industrial heat sink technologies.

A heated aluminum billet is pushed through a custom die.

Resulting in a continuous heat sink profile being manufactured.

You can get extruded heat sinks with:

• Straight fins

• High-density fins

• U-Fins

• T-Fins

• Custom mounting features, etc.

5. Industrial Heat Sink Materials

The material you choose will affect your heat sink’s performance.

Aluminum

Aluminum is by far the most used material for industrial heat sinks.

Aluminum offers:

• Excellent thermal conductivity

• Low density

• Corrosion resistance

• Superb extrusion capabilities

• Reasonable price

Therefore, aluminum is used in many industrial applications.

6063 aluminum is commonly used for heat sink extrusions.

6061 aluminum has higher mechanical strength but lower thermal conductivity.

Copper

Copper has a higher thermal conductivity than aluminum.

Therefore, copper is used in high-performance industrial heat sinks.

The problem is that copper has a higher density and is more expensive.

As a result, you typically only see copper heat sinks used in high heat flux applications.

Copper-Aluminum Hybrids

These heat sinks use both copper and aluminum in the heat sink.

Such as a copper base with aluminum fins.

By combining these two materials you get the benefits of both.

6. Industrial Heat Sink Design Factors

There are several things you should consider when designing a heat sink.

Heat Load

How much heat does the component produce?

A heat sink for higher heat loads will be larger.

Thus, heat load is the first thing you should consider when choosing a heat sink.

Fin Design

The heat transfer area is controlled by the fin design.

Fin design includes:

• Fin height

• Fin thickness

• Fin spacing

• Fin density

• Fin length

As you can see, many variables go into the fin design.

Airflow

Heat sinks can use natural convection or forced-air(convection).

Natural convection heat sinks require a larger surface area.

While adding a fan allows a heat sink to dissipate more heat.

As a result, airflow is a big consideration when choosing a heat sink.

Installation Environment

Heat sinks for industrial equipment have limited space.

As a result, the heat sink must fit into the space provided.

Take note of the height, width, length, mounting holes, cable clearance, etc.

Environmental Conditions

Heat sinks may be exposed to dust, moisture, vibration, chemicals, etc.

Therefore, you may need heat sinks with special coatings or stronger heat sinks.

7. Industrial Heat Sink Manufacturing Process

The manufacturing process will vary based on the type of heat sink.

However, here is a generalized process that most heat sinks will go through.

Step 1: Design

The engineers will figure out:

• Heat load

• Physical dimensions

• Material

• Airflow requirements

• Mounting details, etc.

As a result, the heat sink design is based on thermal and mechanical requirements.

Step 2: Material Preparation

The manufacturer will cut up sheets of aluminum or copper.

Step 3: Forming

The manufacturer forms the heat sink to the desired shape.

Common industrial heat sink manufacturing processes include:

• Extrusion

• Die casting

Step 4: Cutting

Profiles will be cut to the desired dimensions.

Step 5: CNC Machining

Mounting holes and other precision features will be CNC machined.

As a result, this will improve the heat sinks durability and appearance.

Step 7: Assembly

Some heat sinks will have additional components such as:

• Heat pipes

• Fan

• Thermal pad

• Mounting clips

Industrial motor drives may run continuously for long periods of time.

Effective thermal management helps ensure long-term reliability in these devices.

Welding Equipment

Welding machines can produce significant amounts of electrical heat.

Heat sinks are used to cool the power electronics in these devices.

Industrial Power Supplies

Industrial power supplies may need to handle large electrical loads.

As a result, reliable cooling is required to prevent the power supply from overheating.

Solar Inverters

Solar inverters are used in solar power systems.

Like other power electronic systems, solar inverters require effective thermal management to ensure reliable operation.

EV Charging Equipment

Electric vehicle chargers contain high-power electronic components.

It is necessary to use heat sinks or other methods to effectively cool these components.

Heat sinks can be used to cool all sorts of industrial electronics, such as:

• Power modules

• Control electronics

Telecommunications Equipment

Telecom equipment can often operate 24/7.

9.Industrial Heat Sink vs Standard Heat Sink

A practical example would be an industrial inverter. This may require a custom aluminum extrusion heat sink design.

On the other hand, a consumer electronics product would typically use a standard off-the-shelf heat sink profile.

10.How to Choose an Industrial Heat Sink

Here are some factors to consider when choosing the right industrial heat sink.

Determine Heat Output

First, determine the thermal load of the component.

You can use this information to calculate the required thermal resistance of the heat sink.

Check Airflow

Decide if the system will use natural convection or forced air cooling.

You can choose the appropriate fin design based on the cooling method.

Select Material

Aluminum offers low weight and cost-effective thermal performance.

Copper offers better thermal conductivity at a higher price.

Consider using a hybrid heat sink if both properties are important for your design.

Check Dimensions

Double-check that the heat sink will fit into the available space.

Evaluate Environment

Take note of the following environmental factors

• Temperature

• Humidity

• Dust

• Vibration

• Corrosive chemicals/materials

The heat sink should be designed to withstand the conditions present in the device’s operating environment.

Consider Production Volume

High-volume industrial heat sinks are usually produced with extrusion machines.

Low-volume or custom heat sinks are usually CNC machined.

The manufacturing method you choose will affect the unit cost of your heat sinks.
