The difference between normal temperature chiller and low temperature chiller

Ambient coolers and cryogenic coolers are two different types of cooling equipment used to reduce the temperature in equipment or systems. Their main differences lie in the cooling temperature range, usage scenarios and technical principles.

 1. Normal temperature cooler

 Definition: A normal temperature cooler refers to a cooling device that reduces the temperature of an object or system to close to or slightly below the ambient temperature.

 Features:

 Cooling temperature range: usually cooled to around ambient temperature (for example, 20°C to 30°C), without significant low-temperature effect.

Cooling medium: Air, water or other liquids (such as oil) are usually used as cooling media to remove heat through natural convection or forced convection (such as fans, water pumps).

Usage scenarios: Commonly used in daily cooling of mechanical equipment, such as heat dissipation of engines, generators, transformers and other equipment. It is also used in processes that require heat dissipation in industrial production, such as chemical reactions and product cooling in food processing.

Technical principle: Utilize the temperature difference of the natural environment to achieve heat dissipation through conduction, convection and other methods.

2. Low temperature cooler

Definition: A cryogenic cooler is a cooling device used to reduce the temperature of an object or system to much lower than the ambient temperature. It is usually used in situations where low or ultra-low temperature conditions are required.

Features:

Cooling temperature range: can drop below 0°C, even to -40°C, -80°C, or lower, depending on cooler design and technology.

Cooling medium: Low-temperature coolers often use refrigerants (such as Freon, ammonia) or low-temperature media such as liquid nitrogen and liquid helium to achieve low-temperature cooling through refrigeration cycles (such as vapor compression refrigeration, absorption refrigeration, etc.).

Usage scenarios: Commonly used in scientific research laboratories (such as low-temperature physics research), medical equipment (such as cryotherapy, low-temperature storage), food freezing and preservation, chemical production (such as liquefaction of gases) and other occasions that require low-temperature environments.

Technical principle: Utilize compressor refrigeration, absorption refrigeration or other refrigeration technologies to achieve significant cooling through the circulation of refrigerant.
