<p>A heat exchanger (100) comprises an inlet collecting pipe (10), an outlet collecting pipe (20) and a heat exchange pipe and a gas pipe (30) connected between said inlet and outlet connecting pipes (10, 20). The inlet collecting pipe (10) comprises at least two separate chambers, a two-phase refrigerant chamber (12) for containing gas- or liquid-phase refrigerant entering the inlet collecting pipe (10), and a liquid refrigerant chamber (16) for containing liquid-phase refrigerant after separation. Gas- or liquid-phase refrigerant entering the inlet collecting pipe (10) is first contained within the two-phase refrigerant chamber (12), then, after separation, liquid-phase refrigerant enters the liquid refrigerant chamber (16), then enters the heat exchange pipe for heat exchange; after heat exchange, the refrigerant enters the outlet collecting pipe (20). Gas-phase refrigerant flows to the outlet collecting pipe (20) through the gas pipe (30).</p> |
