Problems solved by technology

At the same time, the microchannel heat exchanger is used as the heat exchanger of the external unit. When the external unit defrosts, the defrosting water flows to the chassis through the collecting pipe, and the defrosting water accumulates on the collecting pipe, resulting in water accumulation and reducing the defrosting performance. frost efficiency

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] Such as figure 1 and figure 2 As shown, according to the header of the present invention, the surface where the header is connected to the microchannel tube 2 is provided with a drainage structure. In the present invention, a drainage structure is arranged on the surface where the collecting pipe is connected with the microchannel pipe 2, so that the defrosting water can be taken off smoothly, thereby preventing the defrosting water from accumulating on the surface of the collecting pipe and improving the defrosting efficiency.

[0022] Preferably, the drainage structure is a drainage slope 4, which is more conducive to drainage. More preferably, the drainage slope 4 is an inverted "V"-shaped drainage slope 4, that is, defrosting water is discharged to both sides, thereby shortening the drainage stroke and improving drainage efficiency. More pre...

Abstract

The invention aims at providing a flow collecting pipe, a micro-channel heat exchanger and an air conditioner. According to the flow collecting pipe, a water drainage structure is arranged on the surface, connected with a micro-channel pipe, of each flow collecting pipe. According to the flow collecting pipe, the micro-channel heat exchanger and the air conditioner, the water drainage structure is arranged on the surface, connected with the micro-channel pipe, of each flow collecting pipe, water generated by defrosting can be drained off smoothly, and thus the water generated by defrosting is prevented from being gathered on the surface of each flow collecting pipe; and defrosting efficiency is improved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a header, a microchannel heat exchanger, and an air conditioner. Background technique [0002] With the development of air-conditioning heat exchanger technology, micro-channel heat exchangers have become the focus of research and attention on high-efficiency heat exchangers in the industry due to their advantages such as high heat transfer efficiency, small size, light weight, less refrigerant perfusion, and compact structure. At the same time, the microchannel heat exchanger is used as the heat exchanger of the external unit. When the external unit defrosts, the defrosting water flows to the chassis through the collecting pipe, and the defrosting water accumulates on the collecting pipe, resulting in water accumulation and reducing the defrosting performance. frost efficiency. Contents of the invention [0003] The invention aims to provide a collecting pipe for preventing wa...
