Thermal transfer roller assembly

Abstract

The utility model provides a heat transfer roller assembly, and belongs to the technical field of machinery. The problem of poor stability in the prior art is solved. The heat transfer roller assembly comprises an outer cylinder, an inner cylinder, a first end cover and a second end cover, the inner cylinder is sleeved with the outer cylinder, the outer cylinder and the inner cylinder are fixedly connected, the two ends of the inner cylinder extend out of the outer cylinder, the first end cover is located at one end of the outer cylinder and fixedly connected between the outer cylinder and the inner cylinder, and the second end cover is located at the other end of the outer cylinder and fixedly connected between the outer cylinder and the inner cylinder. A gap is formed between the outer cylinder and the inner cylinder, a heating cavity extending from one end to the middle is formed in the inner wall of the outer cylinder, and a guide-in channel capable of guiding a fluid heating medium into the heating cavity is formed among the inner cylinder, the first end cover and the outer cylinder. The heat transfer roller assembly is high in stability.
