Apparatuses, systems and methods are directed to heat exchangers that are made of microchannel tubes and that have offset fins of various geometries and density. The heat exchanger coils can be implemented in various refrigeration and/or heating, ventilation, and air conditioning (HVAC) units or systems thereof.

Heat exchanger coil with offset fins

Embodiments of a heat exchanger, e.g. a micro-channel heat exchanger are disclosed. The heat exchanger may include a plurality of rows of micro-channel tubes, each of which can be configured to direct a working fluid in a specific direction. The heat exchanger may include one or more distributors in a distribution header of the heat exchanger, each of which can be connected to a different application circuit (e.g. a refrigeration circuit) so that a capacity of the heat exchanger may be regulated. The heat exchanger as disclosed herein can be used as an evaporator and/or a condenser in a refrigeration system.
