High performance 70K cryocooler

The High Performance 70K Cryocooler is a state-of-the-art cooling system designed to operate at temperatures as low as 70 Kelvin. It is engineered for commercial applications where compactness, low cost, high reliability, and high performance are paramount. This Cryocooler is capable of providing 2 to 3 Watts of cooling power at 70K, making it ideal for a variety of cooling applications in the infrared detection and scientific research fields. It features an in-line configuration for the pulse tube, which is optimized for high cooling performance, and the dimensions of the pulse tube, regenerator geometry, and phase shifter are fine-tuned through experimental methods to enhance efficiency .

Product Advantages:

1. High Cooling Efficiency: The cryocooler is designed to achieve a cooling capacity of 2.5 Watts at 70K with only 100 Watts of electrical input, demonstrating its high efficiency in converting electrical energy into cooling power.

2. Reliability and Long Life: With component reliability tests conducted, including mechanical fatigue of the flexure bearings and contamination of the helium working gas, the cryocooler is expected to have a lifetime of more than 50,000 hours, ensuring long-term reliability and minimal maintenance.
