Embodiment Construction

[0021]Various embodiments of the micro-channel heat exchanger of the present invention will be described in conjunction with the accompanying drawings. It shall be noted that various embodiments described below are only for illustration of the present invention but not intended to limit the present invention.

[0022]FIG. 1 is a partial perspective view of a first preferable embodiment of the micro-channel heat exchanger of the present invention. A micro-channel heat exchanger in accordance with the present invention typically comprises an upper manifold 11a, a lower manifold 12a (see FIG. 3), a plurality of micro-channel flat tubes 21a respectively connected to the upper manifold 11a and the lower manifold 12a, and a plurality of rows of fins 31a spaced apart by the micro-channel flat tubes 21a. Both ends of each micro-channel flat tube 21a are respectively inserted into the interiors of the upper manifold 11a and the lower manifold 12a and are fixed with the upper and lower manifolds...

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is entitled to the benefit of and incorporates by reference essential subject matter disclosed in Chinese Patent Application No. 200910002435.9 filed on Jan. 20, 2009.TECHNICAL FIELD[0002]The present invention relates to a heat exchanger and more particularly to a micro-channel heat exchanger.BACKGROUND ART[0003]Compared with the conventional heat exchanger, the micro-channel heat exchanger of the present invention has advantages such as higher heat exchange efficiency and less usage of working medium. Since the industry at present places great emphasis and sets higher requirements on environmental protection and energy conservation, the micro-channel heat exchanger has been widely used in many industries owing to its own advantages, for instance, air-conditioning industry, automobile industry and chemical mechanical industry.[0004]Due to particular design requirements or mounting space constraints, the micro-channel heat...
