Embodiment Construction

[0023] Unless otherwise specified, the terms used in the context of the present invention have the meanings given below. Other terms not specifically given herein have their usual meanings in the art.

[0024] Such as figure 1 , figure 2 and image 3 , the microchannel evaporator according to the embodiment of the present invention includes a distribution pipe 3, and the distribution pipe 3 is a flat tube, such as a linear flat tube, such as Figure 4 As shown, the distribution pipe 3 can be, for example, L-shaped when viewed from the top view, so as to meet the needs of the internal structure and heat exchange efficiency of the micro-channel evaporator. Since the height of the flat tube-shaped distribution pipe is significantly reduced, the height of the refrigerant in the distribution pipe is correspondingly reduced, and the refrigerant is not prone to stratified flow in the distribution pipe, or the degree of stratified flow is significantly reduced. distribution is mu...

Abstract

The invention provides a microchannel evaporator and an air conditioner with the microchannel evaporator. The microchannel evaporator comprises a distribution pipe, wherein the distribution pipe is a flat pipe. According to the microchannel evaporator, the distribution pipe is the flat pipe; the section of the distribution pipe is in a flat shape; and the thickness of the distribution pipe is small, so that a refrigerant is prevented from forming laminated flow in which a gaseous phase is positioned on the upper side and a liquid phase is positioned on the lower side in the distribution pipe. In addition, according to the microchannel evaporator, sizes of distribution holes and distance between the adjacent distribution holes are optimized, and the phenomenon of nonuniform distribution of the refrigerant caused by different flow resistances in the flowing process of the refrigerant in the distribution pipe can be improved effectively, so that after being distributed by the distribution pipe, the refrigerant entering a collecting main and the refrigerant entering the flat pipe of the evaporator from the collecting main flow uniformly, and are high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a micro-channel evaporator, in particular to a micro-channel evaporator with distribution pipes and an air conditioner comprising the micro-channel evaporator. Background technique [0002] Micro-channel evaporator, also known as parallel flow evaporator, the main components include header, micro-channel flat tube and louver fins. The perforated flat tubes and the louver fins connected to them exchange heat, thereby achieving the effect of cooling the environment. [0003] During the operation of the micro-channel evaporator, the refrigerant enters the header through the inlet pipe, and then is distributed to each micro-channel flat tube by the header. The distribution pipes in the prior art are currently circular pipes. For example, the Chinese utility model patent (authorized announcement number CN201522230U) discloses a distribution pipe and a heat exchanger with the distribution pi...
