Abstract

This application provides a heat exchanger (1) capable of recovering lubricating oil according to liquid level changes using the heat exchanger (1) as an evaporator.The heat exchanger (1) includes a heat exchanger shell (101), a refrigerant inlet (102), a refrigerant outlet (103), a heat exchange tube bundle (104), a first lubricating oil return port (105) opened on a side surface of the heat exchanger shell (101), and a second lubricating oil return port (106) opened on the side surface of the heat exchanger shell (101) and closer to the top of the heat exchanger shell (101) than the first lubricating oil return port (105).By arranging the first lubricating oil return port (105) and the second lubricating oil return port (106) at different positions in a height direction of the heat exchanger shell (101), when the working condition of the heat exchanger (101) changes, the lubricating oil return port (105,106) matched with a liquid level in a heat exchanger shell cavity (101a) is switched, thereby avoiding the problem that an operation of a compressor is affected due to no oil recovery that may occur when the liquid level in the heat exchanger shell (101) fluctuates excessively due to only using one fixed lubricating oil return port.
