The shell is made of stainless steel or carbon steel, the heat exchange plate bundle is placed in the shell, and the heat exchange plate bundle is fixedly welded with the shell through end plates on two sides and then is arranged on the support; the plate-pass medium inlet hole and the plate-pass medium outlet hole are respectively positioned at the lower end and the upper end of the end plate; the shell pass medium inlet and the shell pass medium outlet are respectively positioned at the upper side and the lower side of the shell; arc flow guide blocks are additionally arranged between the shell and the heat exchange plate bundle and close to the shell pass medium inlet and the shell pass medium outlet, so that the shell pass medium is fully circulated in the shell, and short circuit is avoided; the plate-pass medium inlet pipe and the plate-pass medium outlet pipe are respectively connected with the inlet and the outlet on the heat exchange plate bundle.
The heat exchange plate bundle is formed by sequentially laser welding the excircles of the heat exchange plates of a plurality of groups of adjacent heat exchange plate pairs, the inlet holes and the outlet holes of the two heat exchange plate pairs are aligned, and the two groups of holes are sealed by laser welding, so that fluid turbulence is realized to the maximum extent, and the heat exchange surface is large and sufficient. The heat exchange plates are preferably corrugated plates or S-shaped plates and are made of stainless steel or other anticorrosive metal materials; and to prevent the heat exchanger from being blocked, the heat exchanger plates are preferably circular. The diameter of the heat exchange plate is 0.2-1.4 m, the corrugation depth is 2-10 mm, the corrugation pitch is 10-20 mm, and the heat exchange plate is provided with a plate-pass medium inlet hole and an outlet hole.

The refrigerant absorbs the heat of the secondary refrigerant and evaporates into gas and then flows out of the shell-side medium outlet, and the secondary refrigerant releases heat and then flows out of the plate-side medium outlet. Oil drops formed by the oil film of the refrigerant medium are discharged to the edge of the heat exchange plate bundle along the inclined corrugated flow channel of the heat exchange plate to the bottom of the plate-shell heat exchanger.
