    摘要: A microchannel heat exchanger. The heat exchanger includes two parallel collecting pipes on two sides, and a group of microchannel flat pipes between the two sides, and both ends of every microchannel flat pipe are connected to the collecting pipes. Tube walls of the microchannel flat pipe are tightly fit and fixed on the plate shaped heat conducting fin. A microchannel heat exchanger according to the invention gives good strength to the microchannel flat pipes, so as to avoid bending. Additionally, it increases the thickness of microchannel flat pipe, which can substantially prevent it from being worn or exposed. Moreover, the gap due to length error can be eliminated. Lastly, the thermal conduction capability is improved, which reduces the usage of silicone grease, and makes its application becomes more convenient.
