RIGID- A Leading And Reliable Manufacturer of Mini Liquid Chiller

High temperatures are a huge enemy of electronic appliances. Elevated heat can cause damage and compromise performance. Depending on the damage severity, it could destroy the device and render it unusable. That’s why you need reliable electronics cooling systems that can ensure your products continue functioning at optimal levels.

RIGID designed a unique mini chiller system for electronics cooling. We’ll tell you more about the system’s specifics in this article. You’ll also learn details about the direct expansion cooling systems, ad why it’s important to have active cooling!

 

What Is a Direct Expansion System?

If you follow trends in the heating and cooling industry, you know the direct expansion system is the latest hit. That’s because it combines optimal performance with convenience. The installation process remains simple while you still have an efficient cooling solution.

A direct expansion system refers to an installation where the chiller is the part of the product you are cooling. The device contains the evaporator, which minimizes the work around tubing and installation. You can integrate the chilling solution into your application, which is also a huge space saver.

The evaporator inside the product contains the refrigerant. The coil expands and absorbs the heat to cool down the area.

Why You Should Choose a Direct Expansion System

Direct expansion (DX) is an excellent pick for electronics cooling. If you choose it for your application, you’ll get the following benefits:

  • It’s easy to install. That minimizes the hassle but also the potential costs of installation.
  • It minimizes required space. Instead of adding it as a separate component, you put the electronics cooling system as part of your device. Therefore, it doesn’t take any additional room.
  • Easy to adjust and maintain. You can set the system to the desired settings easily, especially if you use RIGID’s solution. Our chiller allows you to pick the desired speed, which sets the desired temperature accordingly.
  • Spending little energy. A mini chiller has the significant advantage of utilizing little energy. Since it is compact, it doesn’t need as much energy as bigger devices. Premium mini cooling solutions have the same performance as larger alternatives. That means you’ll still get the expected results while spending less on energy.
  • A minimal noise leve RIGID understands that an electronics cooling fan can be noisy. That’s why it worked hard on reducing the noise level to less than 40dB. That would be similar like you are talking to someone in a library by using a quiet voice.

 

How Does a Direct Expansion System Works for Chilling?

This system has multiple components, including a valve, evaporator, condenser, compressor, and flow control unit. It’s vital to note that you can expect chilling with a normal valve. But if you use a reversible valve, it’s possible for the cooler to work as a heating system, too. That increases the device’s versatility and maximizes its value for money.

The flow control unit is in charge of expanding the refrigerant. RIGID has an electronics liquid cooling solution that includes a liquid refrigerant. The capillary tube or valve for thermal expansion serves for flow control.

If you check the compressor, you’ll find the receiver after it. That’s what serves for storing high-heat and high-pressure liquid refrigerant. From this component, there is a liquid path that the refrigerant follows to the thermal expansion valve.

The flow control reduces the liquid pressure to the pressure of the evaporator. The temperature that the liquid refrigerant has once it reaches the evaporator should be lower than the area it tries to cool down. Some liquid will vaporize to ensure the refrigerant reaches the desired temperature in the evaporator.

 

What Happens in the Evaporator Coil?

The next step involves the liquid vaporizing in the evaporator coil. This component maintains a steady pressure and temperature. The heat goes through the evaporator’s wall to the liquid that vaporizes. As time passes, more of the refrigerant vaporizes until it completely vaporizes. There’s also no more moisture in the air. The evaporator coil condenses it.

If you look underneath the coil, you’ll find a condensate pan. It will catch the water that drips down. From there, it moves the water to the drain. It’s necessary to connect a tube or a hose that will ensure the water can reach the drain.

It’s easier if the pan is below the water that’s dripping. That way, you can let gravity do its job. But if the water has to go up to the condensate pan, you will need a pump. The pump will ensure the water goes up and reaches the drain. The reason you do this is to remove the humidity from the outside area.

 

The Compressor Starts Attracting the Vapor

A compressor is another important component of an electronics cooling system. You’ll find a suction inlet on this part. That inlet has a suction path where the vapor goes. So, the evaporator creates vapor, and then it goes to the compressor.

This part does the job of compressing the vapor. That way, it increases in pressure and temperature. The final step is the compressor discharging the vapor. It follows the discharge path designed when creating the entire system. The vapor proceeds into the condenser coil.

 

What Happens When the Vapor Reaches the Condenser Coil?

We could describe the next step as condensation. The condenser will receive the vapor that discharges from the compressor. This coil also has a fan, which is in charge of cooling the air. Thanks to that, the heat cools down, and the air is now at a much lower temperature. After this occurs, there is a vapor pressure and temperature. The condenser removes more heat as time passes, which leads to the vapor converting into a liquid state.

Once the condenser coil pushes out the vapor, it will be in a cool-down and condensed state. In that condition, the vapor moves into the receiver. That’s the starting position where it’s ready to circulate again. The receiver keeps the liquid as long as necessary until the evaporator requires a new supply of refrigerant.

 

Why Are Active Cooling Systems Better Than Passive Cooling Options?

The crucial difference is the temperature that these two systems can reach. If you use a passive cooling approach, the lowest point will be the ambient temperature. That means your electronics could reach the temperature of the room. However, there’s no option for it to go lower than that. If you use an active cooling system, it will have extra energy. Think of it as a power electronics cooling solution that can reach the desired temperature that your device requires.

Let’s talk about the working process of these two options!

 

How Passive Cooling System Works

These systems usually have ambient air as the ultimate heat sink in an enclosed interface. This interface will increase its temperature until it is hot enough to start releasing the heat into the nearby area. You can use various approaches, such as heat pipes, conductive chassis, and liquid coolant loops to decrease this temperature rise. The problem is these devices won’t deal with the thermal resistance that appears when the heat moves to the outside area. You can use fans, but only to decrease the enclosure surface to the heat level of the ambient air. That’s why your electronics could reach heat levels above the ones recommended for their performance. It frequently happens if the temperature is high in the area.

 

How Active Cooling Works

These systems come with additional energy that helps to lower the heat to the desired level. They operate to decrease the temperature of any part that has air exposure. That way, they move more heat to the area. Subsequently, it reduces the temperature on the parts that are directly in touch with your device.

You can use different technologies for active cooling. If you are looking for an effective way that won’t consume a lot of energy, vapor compression systems are your best bet. These are light, which means they won’t add much extra weight to your product. Vapor compression doesn’t consume a lot of energy, which makes it a smart and eco-friendly solution.

RIGID utilizes vapor compression in mini chiller systems. That allowed us to develop a unique solution that has versatile applications. Our mini cooler has become popular across various industries, and we are proud of that achievement!
