The invention discloses a turbulent single-system evaporator for a heat pump unit. The evaporator comprises a shell, copper pipe, a front end cover, a rear end cover and spoilers; a front bottom plateand a rear bottom plate are welded to the two ends of the outer shell respectively, and the front bottom plate is a round plate, and is welded to the front end of the shell; the inner wall surfaces and the outer wall surfaces of the copper pipe are both surfaces with threads; a transverse baffle is arranged in the middle of the inner side of the front end cover; the rear end cover is welded to the rear end of the shell, and the rear end cover is formed by welding a cylindrical shell and part of a spherical surface; and the spoilers are segments with the arc lengths larger than semicircles, and the arrangement mode is that parts the spoilers are arranged uniformly at intervals along the interior of the shell. According to the evaporator, the shell is a relatively thin shell, parts on the front end and the rear end
