FPSC-Free Piston Stirling Cooler

Free Piston Stirling Cooler
FPSC (Free Piston Stirling Cooler) is a new type of completely CFC-free, high efficiency, energy-saving, and environmental protection Cooler, which uses a small amount of helium as the coolant.

FPSC also is a kind of Magnetic Levitation Compressor (MagLev solution). But it is even more efficient chiller compressor, low energy cost, and consumption. It is small, portable, and it is widely used for precise temperature control for under -170℃ maximum.

RIGID, one of the leading Chinese companies in terms of innovation, designed a Free-Piston Stirling cooler – FPSC. The unit takes the entire product to a whole new level where it can save a lot of energy and significantly improve efficiency. The default version of Stirling coolers includes pistons, heat exchangers, and compression spaces. But we are seeing the technology advancements in all industries, such as Biotech, Pharmaceutical, Energy, Chemical, Foods, logistics, Metrology.

RIGID Free-Piston Stirling cooler is a game-changer for next-generation ultra-deep freezing! Read More...

FPSC Stirling Cooler Application Principles
To cool air in a compact and confined area

1.
Direct Cooling with Conductive Connection
2.
Indirect Cooling with Heat Exchanger+Fan
3.
Direct Cooling with Thermosyphon
4.
Direct Cooling with Brine/Glycol/Nitrogen
1

Cooling performance-Least:
Aluminum plate isnot uniformly and the thermal resistance between the aluminum plate and inside air is relatively large. Limited effective volume.

Influence of frost on cooling-Little:
The surface area of the aluminum plate exposed to the inside air doesn't become smaller when aluminum plate surface is covered with frost.

Others:
The vibration of the FPSC is conducted to the insulated container and aluminum plate directly and they can become a source of noise.
2

Cooling performance-Best:
The thermal resistance between cold side of FPSC and heat exchanger is relatively small. The thermal resistance inside air is relatively small too.

Influence of frost on cooling-Large:
When the space is filled with frost, air can't flow there. The surface area of finned plate exposed to the inside air becaomes smaller and cooling performance is reduced.

Others:
1. It is necessary to specify a fan motor suitable for operation at desired qorking temperature.

2. The heat from the fan motor adds an additional heat load and reduces the overall cooling performance.
3

Cooling performance-Better:
Aluminum plate is cooled more uniformly than "1". Two-phase heat transport allows for the lowest thermal resistance between the aluminum plate and FPSC.

Influence of frost on cooling-Little:
The surface area of the aluminum plate exposed to the inside air doesn't become smaller when aluminum plate surface is covered with frost.

Others:
1. It is necessary to define and prepare a suitable working fluid for desired operating temperature.

2. It is necessary to prepare charging equipment for working fluid.

4

Cooling performance-Better:
Copper tube is attached on aluminum plate with more freedom than "3". Plate is cooled more uniformly than "3" but results in a higher thermal resistance.

Influence of frost on cooling-Little:
The surface area of the aluminum plate exposed to the inside air doesn't become smaller when aluminum plate surface is covered with frost.

Others:
1. It is necessary to prepare suitable brine and pump for desired operating or storage temperature.

2. The heat from the pump motor adds an additional heat load and reduces the overall cooling performance.

3. It is necessary to take precautions against potential brine leakage.

Stirling Cooler Factory
Stirling technology has been used in military and aerospace fields for more than 20 years.

However, due to its high price, it has not been used in the mass market, and there are not many related application products.

After 3 years of efforts, RIGID engaged with a China researchinstitue and has successfully launched a series of affordable quality products for deep freezing.
