About Liquid Cooling Plates: You Need To Know


Have you ever wondered how the freezer or other high-power cooling devices work? If you research this technology, one term you will encounter severally is a liquid cold plate. So, one of the critical pieces to understanding how cooling solutions function is learning about liquid cold plates, sometimes known as liquid cooling plates.

What is a liquid cooling plate?

Generally, a cold plate is a device for heat absorption, mainly used in electronic devices. So, a liquid cold/ cooling plate uses a single-phase liquid to cool a device. It transfers heat from the device to the liquid, removing heat from a specific setting or box. Liquid cold plates are currently the most popular freezers and various applications technology.

Essential things you should know about liquid cold plates

There is more to these devices than the definition above explains. Below are some critical things you should know about liquid cold plates:

a. How does a liquid cooling plate work?

Liquid cold plates need electricity to work. So, when you supply them with electricity, their liquid freezes. This happens fast because the special liquid is built to freeze faster but takes a long time to melt. So, as long as the electricity supply is constant, the liquid remains frozen. However, when the electric supply is cut, the liquid will melt over a long time, usually several hours.

So, the metal plate absorbs the heat from a device, then transfers it to the liquid, which circulates it. Since the electricity keeps the liquid cool, the heat from the metal plates will not build up. So, as long as the electric supply is constant, the liquid will circulate the heat from the plate.

b. Applications of liquid cold plates

Liquid cold plates are primarily applied in high-power machinery and high-end equipment. The applications are limitless. In other words, any device that emits a lot of heat can use cold plates. However, here are some (not all) of their most common applications:

  • Heating systems for buildings
  • Lasers
  • Medical devices
  • Electric vehicles
  • Refrigeration devices
  • High-power electric equipment

c. Types of liquid cooling plates

There are two primary types of liquid cooling plates. They are:

  • Tubes- the liquid is placed inside a tube, so it does not melt easily. However, the tubing also prevents it from getting cold easily.
  • Channels- this type counts on the fluid path to ensure it remains frozen, regardless of the design.

These devices are also categorized depending on the type of metal used to make the metal plate.

d. How are liquid cold plates installed?

The primary determinant of the installation technique for liquid cooling plates is the device on which they are installed. For instance, the installation of liquid cold plates for freezers differs from those in solar panels and industrial machines. Additionally, the various types of liquid cold systems have diverse installation methods. Their installation methods also depend on their brand and application. Sometimes, the professionals who set them up determine the ideal installation technique.


Liquid cold plates are more effective cooling solutions for electric devices than air cooling. These devices contain two major components; the metal plate and liquid. The metal plate’s role is to absorb heat and transfer it to the liquid from a specific setting or device. On the other hand, the liquid circulates the heat.
