Beschreibung
Zusammenfassung:	A heat exchange device for a single crystal furnace is provided, including a heat exchanger on which an inner chamber for heat exchange defined in a shape of circular truncated cone is formed. A convex portion is defined by a chamber wall of the inner chamber for heat exchange partially projecting along a radial direction of the inner chamber for heat exchange, the convex portion extends along a direction of an axis of the inner chamber for heat exchange, and a minimum distance between an end away from the chamber wall of the inner chamber for heat exchange of the convex portion and the axis of the inner chamber for heat exchange is denoted as L, which is greater than or equal to a minimum radius of a cross section of the inner chamber for heat exchange.
