Description

[0002] The compact micro-channel condenser for agricultural machinery is a high-efficiency heat exchange device specially designed for agricultural machinery (such as tractors, harvesters, etc.), belonging to the field of automobile air conditioning accessories. It solves the heat dissipation needs of agricultural machinery under complex working conditions such as space limitations, dust blockages, and vibration impacts through structural innovation and material optimization.

[0003] It uses multiple parallel aluminum flat tubes (each containing dozens of micro-channels with a diameter of 0.5-2mm), and the refrigerant flows in the micro-channels. The liquid accumulator dryer is directly fixed on the outside of the manifold through brazing, eliminating the need for connecting pipes and reducing the volume, while improving the structural strength and pressure resistance.
