Definitions

  • Exemplary embodiments pertain to the art of heat exchangers and, more particularly, to a micro-channel heat exchanger including independent heat exchange circuits.
  • micro-channel heat exchangers include micro-channel tubes formed in a single serpentine path through which passes a coolant or refrigerant.
  • a fluid flow such as air
  • the fluid flow exchanges heat with the refrigerant.
  • the exchange of heat results in a temperature change of the fluid flow.
  • the exchange of heat is enhanced through the addition of fins that extend between the micro-channel tubes.
  • the micro-channel tubes pass between an inlet header and an outlet header. Fins extend between adjacent micro-channel tubes to enhance heat exchange.
  • the inlet and outlet headers are divided into distinct sections. Each section can then be operated independent of the other.
  • a micro-channel heat exchanger including a first micro-channel conduit having a first end section that extends to a second end section through an intermediate section.
  • the intermediate section includes a plurality of substantially straight sections and a plurality of bend sections that establish a first serpentine path.
  • the micro-channel heat exchanger also includes a second micro-channel conduit having a first end portion that extends to a second end portion through an intermediate portion.
