摘要： A heat exchanger includes a shell; multiple exchange tubes disposed in multiple layers from the center to the wall of the shell inside the shell; a first board and a second board arranged in parallel inside the shell; and a first spiral gas tube winding in a same direction, the first spiral gas tube having a first wall provided with a plurality of first gas pores, and the first spiral gas tube has a first inlet and a first outlet that respectively communicates with out-source gas. The heat exchanger can carry out online disturbance to the fluid in the shell internally, even in the case that the fluid media are dirty and viscous, the mixing of the fluid media tends to be uniform continuously, thus effectively improving the heat exchange effect, and convenient for cleaning, purging and maintaining the interior of the device.
