Abstract
The present invention discloses a micro-channel heat exchanger comprising manifolds, a plurality of micro-channel flat tubes connected to the manifolds, and a plurality of rows of fins spaced apart by the micro-channel flat tubes. The micro-channel heat exchanger is provided with at least one bend designed to avoid the deformation of the fins on two inner sides adjacent to the bend due to crushing and meanwhile maintaining the ventilation and heat exchange functionalities of the bend. For example, the bend may include at least one row of fins where the width of the fins are less than the width of the fins on two sides adjacent to the bend. Alternatively, the gap between the fins in the bend can be greater than the gap between the fins on two sides adjacent to the bend. Still alternatively, the bend can be formed with a space for separating cores of the heat exchanger.
