Heat Pump HVAC Heat Exchanger High-Pressure Resistant Copper-Aluminum Alloy Commercial AC Systems

The coaxial heat exchanger is mainly composed of an inner tube (tube side) and an outer tube (shell side) around the inner tube, forming a concentric structure. During operation, two fluids with different temperatures flow in the annular space between the inner tube and the outer tube to transfer heat. For example, in heat pump applications, one fluid may be a refrigerant and the other may be water or air. Reverse flow of hot and cold fluids to improve heat transfer efficiency. Heat is transferred through the inner tube wall to (or from) the fluid in the outer tube for the purpose of heat exchange. This design allows efficient heat transfer in small spaces and is ideal for compact commercial air conditioning systems.
