摘要： A condenser (100), comprising a shell (112), an inlet pipe (120), and an anti-impact plate (204). The shell (112) has an accommodating cavity (202). The inlet pipe (120) is a circular pipe having a gradually increasing inner diameter from the inlet to the outlet. The inlet pipe (120) is arranged to pass through the upper end of the shell (112), the outlet of the inlet pipe (120) being accommodated in the accommodating cavity (202). The anti-impact plate (204) is accommodated in the accommodating cavity (202), and the anti-impact plate (204) is positioned below the outlet of the inlet pipe (120). There is a gap between the anti-impact plate (204) and the outlet through which fluid flowing from the outlet can flow. The condenser (100) can reduce the friction loss and local resistance of the refrigerant gas flowing into the inlet pipe (120), such that the dynamic pressure of the refrigerant gas entering the condenser (100) is partially converted into static pressure, and reduce the static pressure loss of the refrigerant gas entering the cylinder from the inlet, thereby increasing the condensing pressure of the refrigerant gas in the condenser (100) to enhance the heat exchange performance.
