Abstract

The invention provides a micro-channel heat exchanger and a micro-channel pipe thereof. The micro-channel heat exchanger is easily defrosted, and water drainage of the micro-channel heat exchanger becomes easy. The micro-channel pipe of the heat exchanger is characterized in that a body of the micro-channel pipe is a round pipe, heat exchange fins integrated with the body of the micro-channel pipe are arranged on the peripheral side of the micro-channel pipe, and the round pipe is provided with at least one micro channel for refrigerating fluid to flow.

Description

technical field [0001] The invention relates to a microchannel heat exchanger and a microchannel tube thereof. Background technique [0002] like figure 2 As shown, the microchannel heat exchanger includes two vertically arranged headers 13, 14, and a plurality of horizontally arranged flat tubes 1 are fixedly connected between the two vertically arranged headers 13, 14, and the flat tubes shaped like figure 1 As shown, a plurality of microchannels 11 are arranged in the flat tube 1, and the channel equivalent diameter is 10-1000 μm. like figure 2 As shown, fins 12 are arranged between two adjacent flat tubes 1, and the fins 12 extend in the form of wavy lines between the flat tubes, that is, the fins appear in the form of crests and troughs in turn, within a unit length, The number of crests and troughs of the fins is not limited and can be set according to actual needs. Patent document CN101706225A just records such a microchannel heat exchanger. [0003] Such a mic...
