An inward gas/liquid distribution structure used in microchannel heat exchangers is disclosed. The inward gas/liquid distribution structure can help optimizing refrigerant distribution for a microchannel heat exchanger with long distribution pipe or a microchannel heat exchanger having significant wind field differences. The inward gas/liquid distribution structure includes an inlet header component. The inlet header component has n inlets that are configured to allow gas/liquid to enter the inlet header component, and n is an integer that is greater than or equal to 2. The inward gas/liquid distribution structure also includes m distribution components. The m distribution components are located in the inlet header component and connected to the n inlets, respectively. In an example, the number m equals to the number n.
