How Does 24V Liquid Cooler Work?

24V Liquid Cooler Working Principle

The secret to the efficiency of this small cooler is that it uses a rotary micro-compressor. The working process is quite simple. Everything comes down to circulation or convection of liquid.


The unique liquid inserted by the manufacturer is a heat conductor. It moves from the base unit to the other components that are hooked to the desired application.

By circulating throughout the system, the liquid takes the heat away from the devices or objects it is supposed to cool down.

Once it returns to the base unit, it is hotter than before. That is why the liquid cools down while it passes through the device, and it can continue removing the heat from the application during the next circle it makes.

The liquid used might be a coolant formula, propylene glycol, or distilled water, and that depends on the cooler you purchase or your application. Either way, you will get maximum benefits from the device pumping the liquid through the equipment to the desired use and vice versa.

Why RIGID 24V Liquid Cooler is the Best Cooling Solution?

Using a mini rotary compressor eliminates the need for chemical cold pads or ice. If you browse the market, you will find various cooling solutions.

One of them is dry ice, whose temperature is -90C. That might lead to the chilled water freezing, which can affect the device’s performance, and fail to deliver the expected results.

It is also worth noting that dry ice will also melt after a couple of hours. Once that happens, the only solution is to refill the device. But what if you are not around? You can’t spend seconds refilling the unit?

Another solution might be a fan, but that only has limited effectiveness. You either need a massive fan, which significantly increases the overall cooler size, or you go with a small fan. But in that case, the fan won't be effective, and it might not be able to give you the expected results.

If you are looking for consistent cooling, you will love what this small cooler can do. Even though it comes in a compact pack, it is incredibly powerful. The compressor can work in harsh conditions, which means that it can keep optimal coolness even when it is incredibly hot outside.

And it also works the other way around! If it is cold and you would like it to feel warmer in the room, or you want to increase the temperature for your desired application, RIGID 24V Liquid Cooler can meet your expectations.

All you have to do is to trigger the heating mode and watch the magic happen. Although it is named after its cooling function, the heating option also does an amazing job.

What Are the Potential Applications of the RIGID Liquid Cooler?

Here is an overview of potential applications for the 24V DC liquid cooler - LC3220E-H:

1. Medical Equipment

You might need to keep a consistent temperature of your medical and lab equipment. You can't risk the temperature going up as it could compromise the performance of the equipment, and lead to failure. A small and powerful cooler is the ideal solution to keep the heat level optimal, depending on your needs.

An example of using the product for medical purposes is patient thermal management. If you need to maintain the patient’s body temperature at a certain level, you want a reliable solution that can secure consistent cooling.

The circulation process that this liquid cooler ensures can be efficient to keep the skin cool locally while reducing overall body heat.


You might also use RIGID Liquid Cooler as a medical laser chiller. And don’t worry about the capabilities of the cooler. With its strength varying from 100W to 550W, you can ensure that your customized solution is strong enough for medical lasers.

Many medications, chemicals, and other items should be kept at low-level temperatures. If they get heated, that could compromise their performance and characteristics, and they might become worthless. You can rely on this small cooler to keep the temperature at the required level consistently and without significant variations.

2. Electronics Cooling System

The liquid cooler can be connected to your body by using a cooling suit or vest. That way, you get a solution that can ensure you are always cool or warm, depending on your needs.


Imagine how you can benefit from this application. If you are a race car driver, you will probably be driving at extreme weather conditions. With the adrenaline pumping and the fact that many decisions have to be made in a split second, you can’t afford to fight with excessive heat.

That is where a 24V liquid cooler can be your best friend. The unit is compact-sized, and you can install it virtually anywhere in your vehicle. You use the tubes to connect it to the cooling vest you are wearing, and the system secures the benefits in seconds.

The circulation of the chilling liquid transfers the heat away from your body. The liquid might be heated once it arrives into the cooler, but the task of the device is to cool it down again.

The cool liquid now moves to your cooling vest again to take away the heat. The process is consistent and secures terrific results.

4. Keeping Your Beverages Cold
