Beschreibung
Zusammenfassung:	The utility model discloses a heater and a single crystal furnace thermal field system. The heater comprises at least two oppositely distributed first heating bodies, at least two second heating bodies and at least two connecting foot plates, wherein the first heating body is connected with the second heating body, and an annular heating body is defined by the first heating body and the second heating body; in the circumferential direction of the annular heating body, the two ends of the first heating body are connected to the bottoms of the two adjacent second heating bodies respectively, and the connecting foot plates are fixedly connected to the bottoms of the second heating bodies. According to the heater, the safety distance from the outer wall of the second heating body to the heat preservation cylinder can be increased, then the adjustable range of the wall thickness of the second heating body is increased, the corrosion speed of the second heating body is reduced, the service life of the heater is pro
