Water Cold Plates

Water cold plate heatsinks, also known as liquid cold plate heatsinks, are a type of cooling solution that utilizes water or another liquid to dissipate heat from electronic components. On the other hand, traditional heatsinks are typically made of metal, such as aluminum or copper, and rely on passive air cooling.

 

Copper Cold Plates

Deionized Water Cold Plates

Deionized water cold plate heatsinks are a type of cooling solution commonly used in various electronic devices to dissipate heat generated by components such as CPUs, GPUs, or power modules. They utilize a cold plate, which is a metal plate in direct contact with the heat-generating component, and deionized water as the cooling medium.

 

Dielectric fluids Cold Plates

Dielectric fluid-based cold plate heatsinks, also known as liquid cooling systems or immersion cooling, have gained popularity in recent years for their ability to efficiently dissipate heat from electronic components. Let’s explore the difference between dielectric fluids and traditional air-based heatsinks, as well as their benefits and reliability.

Water and ethylene glycol (EG) Cold Plates

Water and ethylene glycol (also known as antifreeze) are both commonly used as coolants in cold plate heatsinks.

Aluminum Cold Plates

Aluminum cold plate heatsinks are a type of cooling solution commonly used in electronic devices to dissipate heat generated by components such as CPUs, GPUs, or power electronics. The primary purpose of a cold plate heatsink is to transfer heat away from the source and dissipate it into the surrounding environment.

Polymer Cold Plates

Polymer-based cold plate heatsinks are a type of heatsink that utilize polymer materials, such as thermoplastics or thermosetting resins, for their construction. They are an alternative to traditional metal-based heatsinks, which are typically made from materials like aluminum or copper.

Liquid cold plates are heatsinks that use liquid as a cooling medium to dissipate heat from electronic components. Cooling Source manufactures cold plates made of copper or aluminum. In addition, have channels or tubes that allow the liquid to flow through them.

The liquid is usually water, or a water-based coolant circulated through the cold plate using a pump. As the fluid flows through the channels, it absorbs heat from the electronic components. Then it carries it away from the cold plate.

 

Modern electronics are getting smaller and more powerful. This means they generate a lot more heat. In fact, the heat density in some devices has increased by over 50% in the last decade! Traditional cooling methods just can’t keep up. Cold plates offer a smart solution.

These devices use liquid to move heat away from sensitive components. It’s like giving your electronics a refreshing drink! We are experts at making these advanced cooling tools. We follow the newest industry standards to deliver top-notch performance.

Understanding Cold Plate Technology

Cold plate technology is all about efficient heat removal. They use a simple, yet powerful process. Heat moves from the hot component to the cold plate. Then, a liquid coolant carries the heat away.

How Cold Plates Work: A Detailed Explanation

Imagine a hot CPU. It’s making a lot of heat! A cold plate sits on top of the CPU. The heat flows into the cold plate. Inside, a liquid like water moves through channels. The liquid absorbs the heat. The heated liquid then flows away to a radiator. The radiator releases the heat into the air. The cooled liquid returns to the cold plate. This cycle repeats, keeping the CPU cool.

Channel Designs and Materials

Cold plates come in different designs. The channels inside affect performance. Common designs include tube, fin, and serpentine. Tube designs are simple and reliable. Fin designs offer more surface area for better cooling. Serpentine designs create a longer path for the coolant.

Materials matter too. Copper is great at conducting heat. Aluminum is lighter and cheaper. Stainless steel resists corrosion. Each material has its trade-offs.

Key Performance Metrics: Thermal Resistance, Pressure Drop, and Flow Rate

Three things are key when measuring cold plate performance. These are thermal resistance, pressure drop, and flow rate. Thermal resistance shows how well the cold plate moves heat. Lower is better! Pressure drop measures how much the coolant slows down. Higher pressure drop can reduce flow. Flow rate indicates how much liquid moves through the cold plate. Finding the right balance is important.

Applications of Cold Plates

Cold plates are useful in many areas. They cool high-power electronics and medical gear. Also, they are critical for electric vehicles.

High-Power Electronics Cooling

CPUs and GPUs get hot! Without proper cooling, they can fail. Cold plates keep these components cool. This maintains speed and helps lifespan. Power amplifiers also need cooling. Cold plates ensure they work well. Without cold plates, electronics could overheat and die!

Medical Equipment Cooling

MRI machines need very precise cooling. Lasers used in surgery generate a lot of heat. Cold plates keep these machines stable. They ensure reliable and precise medical procedures. The reliability that cold plates give is very important.

Electric Vehicle (EV) Battery Cooling

EV batteries create heat while driving. Too much heat can damage the battery. This reduces its life and performance. Cold plates keep the battery at the correct temp. This extends battery life. Cold plates help EVs go further and last longer. Data shows that batteries degrade faster when they overheat.
