Abstract

The invention discloses a microchannel heat exchanger. The heat exchanger comprises a first collecting pipe, a second collecting pipe, flat pipes and fins, wherein two ends of the flat pipe are connected with the first collecting pipe and the second collecting pipe respectively so as to communicate the first collecting pipe and the second collecting pipe; and the fins are arranged between adjacent flat pipes, wherein the microchannel heat exchanger is bent on a predetermined position between the first collecting pipe and the second collecting pipe so as to ensure that the microchannel heat exchanger is separated into a first heat exchanger part and a second heat exchanger part which are positioned at two sides of the bent position, and the heat transfer coefficient of second fins of the second heat exchanger part is greater than that of first fins of the first heat exchanger part. The microchannel heat exchanger is bent into a shape approximate to A, and the two sides of the bent position have consistent heat exchange amount, so that the heat exchange effect is improved.

Description

technical field [0001] The present invention relates to a heat exchanger, and more particularly to a microchannel heat exchanger having a generally A-shape. Background technique [0002] Microchannel heat exchangers are used in a wide variety of applications, for example in air conditioners. Traditional microchannel heat exchangers are usually flat rectangular bodies, but in some applications, it is necessary to bend the microchannel heat exchanger to form a roughly A-shaped shape, so that the microchannel heat exchanger is divided into two parts located at the bend. The first heat exchanger part and the second heat exchanger part on the side (ie, the refrigerant inflow side and the refrigerant outflow side), the fins of the first and second heat exchanger parts are identical in structure and design. [0003] In use, the inlet air flows from the bottom to the top of the A-shaped micro-channel heat exchanger, exchanges heat with the refrigerant in the flat tube when passing ...
