9.  Parts Of Custom Copper Heat Sink

The custom copper heat sink has the following parts that aid in heat dissipation through the heat sink:

Heat Sink Fins

Heat sink fins refer to a flat plate through which heat dissipates nearby, flowing from one end to the other through the custom copper heat sink.

The arrangement, shape, size, and location of heat sink fin greatly impact their efficiency in dissipating heat.

Heat Sink Base

The heat sink base is a major part of a custom copper heat sink as it allows for heat to flow from one end to the other.

Increasing the thickness of the heat sink base helps reduce the thermal resistance of a custom copper heat sink.

10.  Available Sizes Of Customs Copper Heat Sink

  • 271-482mm heatsinks
  • 186-250mm heatsinks
  • 122-174mm heatsinks
  • 69-120mm heatsinks
  • 19-57mm heatsinks

11.  Factors Determining Customs Copper Heat Sink Price

Factors determining the price of the custom copper heat sink, thus making it efficient for its desired purpose.

Therefore, when choosing a custom copper heat sink to purchase, the following are some of the factors to consider:

Thermal Resistance

The thermal efficiency of a custom copper heat sink is determined by measuring the thermal resistance between the heat sink and the electronic component.

Thermal resistance measures resistance to heat flow between a heat sink and the fluid in motion.

The less the thermal resistance, the more efficient the heat sink as thermal resistance leads to non-uniform heat distribution.

Therefore, copper is the best material for a custom copper heat sink.

Therefore, the less the thermal resistance of a custom copper heat sink, even though it is higher in price but the low the maintenance cost.

A highly thermal resistant heat sink is cheaper and costly to maintain.

Heat Sink Fins

The heat sink fins highly impact custom copper heat sink.

Therefore, thermal conductivity is determined by the electronic cooling efficiency of heat sink fins.

Heat is dissipated into the nearby coolant fluid by heat sink fins received from an electronic device.

As the distance from the heat sink’s base increases, the heat dissipated by a fin to the coolant medium decreases.

Therefore, a custom copper heat sink has high thermal conductivity, thus improving the fins’ overall efficiency.

In addition, the shape, size, arrangement, and location of the heat sink significantly affect the efficient functioning of the fins.

Therefore the better the configuration of the heat sink fins, the higher the prices of a custom copper heat sink.

Durability Of the Heat Sink

The durability of a custom heat sink depends on the material used to design it.

Therefore, a custom copper heat sink designed using copper makes it durable hence the high prices as maintenance costs will be less expensive than other materials such as Aluminium.

Heat Dissipation

Heat dissipation is the heat flow between a heat sink and an electronic component.

Therefore, when choosing an efficient custom copper heat sink, it is advisable to select the well-attached one and use thermal interface material.

The higher a custom copper heat sink can dissipate heat, the more expensive it is as it is efficient.

What Are The Cut Length And Cut Height Tolerance Of Custom Copper Heat Sinks?

Copper heat sinks are therefore manufactured or cut across.

If extruded, the cut length and cut height tolerance are as follows:

  • Maximum height: 60mm
  • Full length: 400mm

If fabricated using a skiving method, then the cut length and cut height tolerance are as follows:

  • Maximum height: 10-40mm
  • Full length: 150mm

How To Test Quality Of Custom Copper Heat Sink

A custom copper heat sink is considered good quality if it is efficient and functional.

A custom copper heat sink is tested by having a heat sink set up. The following are the factors that play a vital role in the heat sink test:

  • Power supply
  • Wind tunnel
  • Velocity sensor
  • Air temperature
  • Thermocouples

Electrical power is dissipated in the form of heat energy using a resistor.

Therefore, a resistor is connected to the heat sink by employing a thermally conductive double-sided tape.

A board that has low thermal conductivity is attached to a resistor.

Heat dissipates in the resistor when a heat sink is mounted on a component, and two paths conduct to the environment.

However, interface resistance is the only thermal resistance to the heat sink and the board from the resistor.

Heat dissipated to the air through the heat sink will not correspond to the energy dissolute in the resistor, thus giving an error in measuring the thermal resistance of the heat sink.

A decrease in board thickness aids in increasing thermal resistance to the air from the board.

Increased airflow velocity through the board and increasing board thermal conductivity decrease thermal resistance.

The following are heat testing methods:

Setting In An Abducted Environment

This type of heat sink testing involves the flow of air. Through the heat sink, airflow is influenced by its fin density.

More airflow passes through the heat sink due to its higher fin density, thus giving a good measure of its thermal performance.

It needs a higher-quality testing facility but is easier to set up.

Set Up In A Duct.

In this heat sink testing method, all the airflow is forced to bypass through the heat sink.

There is no airflow around the heat sink. Setting up is relatively easy. It gives thermal resistance results.

Even though the results are positive when heat sinks are in an unducted application, it can give false data.

Dual Heat Sink Testing

This method of heat sink testing uses a heater sandwiched between two identical heat sinks.

The assembly is on the centerline of a research quality wind tunnel.

There are no heat transfer losses to the air; thus, a suitable method of heat sink testing.

Setting up is time-consuming, and the method velocity is hard to measure; rarely used to test heat sinks.

Determining Thermal Efficiency Of Custom Copper Heat Sink

The factors that determine the thermal efficiency of the custom copper heat sink are as follows:

Material

Therefore, custom copper heat sinks are manufactured using copper with high thermal conductivity.

Copper is the perfect material for heat sinks as it offers corrosion resistance, heat absorption, and thermal conductivity.

Thermal Resistance

measuring the thermal resistance between the heat sink and the electronic component help determine the thermal efficiency of the custom copper heat sink

Thermal resistance measures resistance to heat flow between a heat sink and the fluid in motion.

The less the thermal resistance, the more efficient the heat sink as thermal resistance leads to non-uniform heat distribution.

Therefore, copper is the best material for a custom copper heat sink.

Heat Sink Attachment Method; How Heat Sink Dissipates Heat

The heat sink attachment techniques significantly impact the thermal efficiency of a custom copper heat sink.

Therefore, it is essential to choose an efficient method of fixing a heat sink to an electronic component.

The methods chosen should consider both the mechanical and thermal requirements.

Commonly techniques used to attach heat sinks to an electronic component are:

  • Flat spring clips
  • Thermal tape
  • Epoxy
  • Standoff spacers

Thermal Interface Material; How Heat Sink Dissipates Heat

The thermal interface material help determine the thermal efficiency of the custom copper heat sink.

Also, thermal contact resistance is increased by roughness, gaps, and surface defects, reducing the thermal efficiency of a heat sink.

Thermal contact between a heat sink and an electronic component is reduced, thus increasing heat flow resistance.

Therefore, reducing surface roughness and improving interface pressure helps to reduce thermal resistance, thus increasing thermal efficiency.

If there are limits to this type of reduction method, then it is suitable to use thermal interface materials to reduce heat flow resistance.

Electronic Cooling Efficiency; Heat Sink Fins

The electronic cooling efficiency of heat sink fins help determine the thermal resistance.

Heat is dissipated into the nearby coolant fluid by heat sink fins received from an electronic device.

As the distance from the base of the heat sink increases, the heat dissipated by a fin to the coolant medium decreases.

Therefore, a custom copper heat sink improves the overall efficiency of fins as it has high thermal conductivity.

Size, Shape, Arrangement, And Location Of Heat Sink Fins

Therefore, the size, shape, placement, and location of heat sink fins help determine the thermal efficiency of a custom copper heat sink

Heat sink fins are known for providing cooling functions for heat sinks. Therefore their arrangement is considered most important.

Improving their layout aids in reducing fluid flow resistance hence allowing air to go through a heat sink.

The shape and size of heat sink fin significantly impact their cooling functions.

Thus, improving their shape and size helps maximize the heat transfer density.

To maximize the thermal efficiency of heat sink fins, the shape and arrangements of the heat sink fine improved through modeling.

Surface Finishes For Custom Copper Heat Sink

Some of the surface finishes for custom copper heat sinks are:

Powder Coating

Powder coating is a type of surface finish in which a dry powder is electrostatically applied to the heat sink metal to form a layer.

Anodizing

This type of surface finish increases the thickness of a custom copper heatsink layer through the passive electrolytic process.

Chromate

This type of surface finish makes the custom copper heat sink passive.

Led/tin

This type of surface finish protects the custom copper heat sink from corroding.
