Thermal Management is the ability to control the temperature of a system by means of Technology based on Thermodynamics and Heat Transfer. RIGID Technology has been in miniature cooling systems for 11 years. Our compact liquid modules act as "sub-systems", is easily assembly to customer's device and equipment, and widely used in many industries as well.
As we known all electronic devices and circuitry generate excess heat and thus require thermal management to improve reliability and prevent premature failure. The amount of heat output is equal to the power input, if there are no other energy interactions. There are several techniques for cooling including various styles of heat sinks, thermoelectric, air conditioning and fans, water coolers, and others. In cases of extreme low environmental temperatures, it may actually be necessary to heat the electronic components to achieve satisfactory operation.
If your application requires thermal management? RIGID made a huge success by designing modules and systems that help to cool down the temperature to the desired level. Additionally, these products can maintain that heat level by guaranteeing consistent performance.
If you are looking for a compact and light-weight cooling unit, you are in the right place. Here is a short overview of the compression cooling and circulating systems for active thermal management. Check out different solutions, and don’t hesitate to contact us if you have any questions!
1.
Mini Compressor – Vapor Compression Refrigeration
RIGID put years of hard work into developing a revolutionary solution in vapor compression technology. The mini compressors we've designed are the result of this research. Their main advantage is that they have marvellous cooling performance, while very small size. Additionally, the system features low vibration, which contributes to lowering the noise.
It is true miniature BLDC rotary compressor. That’s why the products we design aren’t an inch bigger than absolutely necessary. We are proud to say that the miniature technology enables compact and lightweight refrigeration systems in the industry. Our customer's laser cooling system features a compact size while maintaining impressive performance.

RIGID mini rotary compressor is extremely efficient, which is possible because it uses the R134A refrigerant. The device is also compatible with natural refrigerant R290 for those who prefer that option. The total weight of the unit doesn’t exceed 720 grams, which is around 1.5 pounds. Our experts implemented a one-cylinder setup under standard ASHRAE requirements.
And here is the best part – the total energy consumption is surprisingly low. You’ll find that it utilizes 40% less energy than other systems. While we are discussing that, let’s mention the noise reduction is around 45dB(A). That’s an impressive advancement compared to the previously used system. It ensures the compressor is quiet and efficient, which means its activity won’t disrupt others. It is very well-received by medical and aesthetic industry for dedical device cooling.
Can You Use the Compressor in Indoor or Outdoor Conditions?
The primary purpose of RIGID’s rotary compressors is indoor use. That could be in vehicles for transport or other indoor settings. The reason for this is that optimal lubrication requires an ambient temperature of at least 5℃.
However, if you require outdoor or hot ambient temperature use, you should be aware that RIGID designed a T-tropical series of its units. These mini compressors can operate at temperatures up to 55℃. That makes them the perfect cooling solution in outdoor environments. You can use it for automotive purposes to reduce and maintain optimal temperatures.
The best part is that RIGID’s compressors can deliver excellent performance and optimal thermal management while maintaining impressive lightness. The compressor that weighs 1.5 pounds can have a 30% better performance than a unit that weighs six times as much.
2. Micro DC Aircon – Air Circulating Systems
The idea of a micro DC air circulating system is simple. It removes the heat from the device to cool it down. The hot air that gets removed from the product circulates through our unit. Thanks to the circulation, it becomes cooler when it returns to the device. That ensures the overall temperature of your product goes down. It’s the perfect option of a CO2 laser cooling and many other applications.
Here is the overview of the main characteristics offered by the Micro DC Aircon systems:
● Voltage. RIGID ensures that you can pick the desired voltage option from 12V, 24V, and 48V adjustments. The DC voltage ensures you utilize minimum energy without requiring converters.
● Weight. The weight varies from around ten to twelve pounds. This is a small difference between the least and most powerful options. It’s worth noting that even the settings with the fewest wattage offer efficient performance.
● Size. The size of our micro DC aircon is 350x260x180 millimeters. That means the entire unit is incredibly small, like a Paper A4 size!
All standard aircon units use the R134A coolant, and they operate with an airflow rate of 28.3CFM at the cold air outlet. You can adjust the desired heat transfer rate, and the unit will exceed all expectations when it comes to managing the target temperature. If you require R290 natural refrigerant or your own design, RIGID is able to customize base on your requirements.
What Are the Main Advantages of the Micro DC Aircon?

That includes medical device chiller, eletronics cooler, EV battery cooling, or a laser cutter cooling system but also other applications across different industries.
What’s the Working Process of a Liquid Circulating System?
The idea is simple, and it all starts with an intuitive design. The fluid goes into a heat exchanger. Heat exchangers, metal shells and tubes, work by transferring heat from one place to another. It transfers heat from one medium to another. These media may be a gas, liquid, or a combination of both. Heat exchangers can improve a system's energy efficiency by transferring heat from systems where it is not needed to other systems where it can be usefully used.
RIGID has two options for our customer's selection:
The two chillers have same configuration and layout, the only difference is different evaporator. Attached are specifications and cooling performance charts, for your reference.
- For Plate Liquid Chiller, in part of the heat exchanger between refrigerant and liquid, it is fin-tube heat exchanger.
- For Coaxial Liquid Chiller, in part of the heat exchanger between refrigerant and liquid, it is double layer pipe heat exchanger.
- Stainless steel liquid cooler. It chooses stainless steel material.
The system requires an external pump but managed to keep a compact size. It also has an impressive capacity and surprising efficiency. It can lower the heat level significantly while maintaining a consistent temperature. It’s perfect for active thermal management, where you need to keep the heat at the same level for a long time.
It’s possible to use the device as part of your chilling system. Alternatively, it’s even possible to integrate RIGID’s liquid circulation system into your setup. That means they can become a part of your product. The increase in weight and size will be only minimal, and the cooling benefits will exceed all your expectations.
4. DC Condensing Unit – Direct Expansion Systems
The main difference between this dc condensing unit and other chiller is that it features direct expansion. This is a subsystem that doesn’t come with an evaporator. Its components are the mini compressor, condenser, filler drier, driver board, capillary, and other parts.
Our condensing unit is an expansion system. It is ultra compact and flexible to customer's applications because it comes without an evaporator. Instead, you have the freedom to customize the cold plate to your requirements. Please note that we can adjust the system to fit your needs.
