[1] [2] The company offers cryogenic systems, including dilution refrigerators [3] and cryocoolers, which are essential for applications requiring ultra-low temperatures. [4] Cryocoolers are for instance a requirement for today’s superconducting qubits to function. [5] In response to increasing global demand, the company has expanded its ...
He founded Sunpower Inc., [35] which researches and develops FPSC systems for military, aerospace, industrial, and commercial applications. A FPSC cooler made by Sunpower was used by NASA to cool instrumentation in satellites. [36] The firm was sold by the Beale family in 2015 to become a unit of Ametek. [37]
Heat exchangers are important components of all cryocoolers. Ideal heat exchangers have no flow resistance and the exit gas temperature is the same as the (fixed) body temperature T X of the heat exchanger. Note that even a perfect heat exchanger will not affect the entrance temperature T i of the gas. This leads to losses.
Pulse tube cryocoolers are used in niche industrial applications such as semiconductor fabrication and superconducting radio-frequency circuits. [1] They are also used in military applications such as for the cooling of infrared sensors. [2] In research, PTRs are often used as precoolers of dilution refrigerators.

The first experimental machines were built in the 1990s, when (commercial) cryocoolers became available, capable of reaching a temperature lower than that of liquid helium and having sufficient cooling power (on the order of 1 Watt at 4.2 K). [6] Pulse tube coolers are commonly used cryocoolers in dry dilution refrigerators.
Maxeon was spun off from SunPower in August 2020. Maxeon was the primary provider of solar panels for SunPower through March 2024. [2] Beyond the United States, Maxeon has sales operations in more than 100 countries and has the rights to use the SunPower brand in countries outside the United States.
A Stirling engine can function in reverse as a heat pump for heating or cooling. Other uses include combined heat and power, solar power generation, Stirling cryocoolers, heat pump, marine engines, low power model aircraft engines, [90] and low temperature difference engines.
