Abstract
The invention relates to a device for controlling the temperature of a process gas and a heat exchanger having such a control device. The control device has an outer housing with an inflow and outflow chamber. Cooled process gas can flow into the inflow chamber, while temperature-controlled process gas can flow out of the control device via the outflow chamber. An inner housing, which is fluidically connected to a hot gas line, extends from the inflow chamber through an element that mechanically separates the chambers into the outflow chamber. An axially movable piston, through which flow can take place, is arranged within the inner housing. The inner housing and the piston have openings which allow fluidic connections to the hot gas line, the inflow chamber and the outflow chamber.
