Problems solved by technology

[0002] At present, in household air conditioners, automobile air conditioners and other air-cooled heat exchangers, extruded aluminum alloy flat tubes are used, and the minimum size of the inner hole is greater than 0.6mm, so it is called a large-scale micro-channel heat exchanger. Although it is much more efficient than traditional tube-fin, tube-belt, parallel-flow, plate-fin, and stacked heat exchangers, it has not yet reached the micro-scale effect.

Embodiment 1

[0014] Such as figure 1 As shown, the heat exchanger for the miniature microchannel metal circular tube of the air-cooled air conditioner described in this embodiment includes an inlet pipe 1, an outlet pipe 2 and a heat exchange mechanism 3, and the inlet pipe 1 and the outlet pipe 2 The heat exchange mechanism 3 is connected by the heat exchange mechanism 3. The heat exchange mechanism 3 is made of a micro-microchannel metal circular tube 4 and a metal wire 5. The outlet pipe 2 is connected with an inner diameter of 0.1 mm, and the metal wire 5 is a weft thread, and is welded with the miniature microchannel metal round pipe 4 . The inlet pipe 1 and the outlet pipe 2 adopt a metal round pipe structure, and holes 6 are formed on the pipe wall, and the micro-microchannel metal round pipe 4 is welded and fixed to the inlet pipe 1 and the outlet pipe 2 through the opening 6 . An anti-corrosion and leak-proof layer is also provided on the surface of the heat exchange mechanism 3,...

Embodiment 2

[0016] Such as figure 2 As shown, the heat exchanger for the miniature microchannel metal round tube 4 of the air-cooled air conditioner described in this embodiment, the inlet tube 1 and the outlet tube 2 are flat tube structures, and the miniature microchannel metal round tube The inner diameter of the tube 4 is 0.4 mm, and the rest of the metal wires 5 form a mesh heat exchange mechanism 3 . Between the inlet pipe 1 and the outlet pipe 2, three layers of stacked heat exchange mechanisms 3 are arranged to form a parallel structure. The inlet pipe 1 and the outlet pipe 2 are also provided with an isolation plate 8 through slotting, and the isolation plate 8 is provided with a drainage hole 7 .

Abstract

The invention designs a heat exchanger provided with micro micro-channel metal circular pipes for an air cooled air conditioner. The heat exchanger comprises an inlet pipe, an outlet pipe and a heat exchange mechanism, wherein the inlet pipe is connected with the outlet pipe through the heat exchange mechanism. The heat exchanger is characterized in that the heat exchange mechanism is constructed by crossly weaving the micro micro-channel metal circular pipes and metal wires; the micro micro-channel metal circular pipes are radial lines with the two ends being connected with the inlet pipe and the outlet pipe and the inner diameters being 0.1-0.4 millimeter; the metal wires are weft lines, and are connected with the micro micro-channel metal circular pipes by welding. The entire heat exchanger is constructed by taking the micro micro-channel metal circular pipes as a major heat exchange mechanism and taking the metal wires as support frameworks.

Description

technical field [0001] The air-cooled heat exchanger of the miniature micro-channel metal circular tube of the present invention relates to all fields of air-cooled industrial air conditioners, civil air conditioners and vehicle air conditioners, or microelectronics and air energy water heaters. Background technique [0002] At present, in household air conditioners, automobile air conditioners and other air-cooled heat exchangers, extruded aluminum alloy flat tubes are used, and the minimum size of the inner hole is greater than 0.6mm, so it is called a large-scale micro-channel heat exchanger. Although it is much more efficient than traditional tube-fin, tube-belt, parallel-flow, plate-fin, and stacked heat exchangers, it has not yet reached the micro-scale effect. Micro-micro-channel heat exchangers are currently mostly plate-type micro-channel heat exchangers, which are mostly used for liquid-liquid heat exchange. However, there is no such structure for air-liquid heat ...
