摘要： The present application discloses a microchannel flat tube and a microchannel heat exchanger. The microchannel flat tube includes a flat tube body and a row of channels. The row of channels is arranged in the flat tube body along a width direction. The row of channels extends through the flat tube body along a length direction. A cross-section of each channel includes a first width in the width direction and a first height in a thickness direction. The row of channels at least includes a first channel, a second channel and a third channel along the width direction. The first widths of the first channel, the second channel and the third channel are decreased at a fixed ratio, thereby facilitating the control of the thickness of the microchannel flat tube and improving the heat exchange efficiency of the third channel.

摘要： A heat exchanger has a collecting pipe, a separator and a number of heat exchange tubes. The collecting pipe has a pipe wall and an inner cavity. The separator is provided in the inner cavity. The separator extends along a lengthwise direction of the collecting pipe. The separator divides the collecting pipe into a first cavity and a second cavity. The heat exchange tubes are arranged along the lengthwise direction. Each heat exchange tube has a first end and an inner cavity. The first end of the heat exchange tube sequentially passes through the pipe wall of the collecting pipe, the first cavity and the separator to be inserted into the second cavity. The inner cavity of the heat exchange tube is communicated with the second cavity. As a result, uniformity of refrigerant distribution in the heat exchanger is improved.
