摘要

The climatic chamber has a Peltier element which has an inner heat sink arranged in inner space and an outer heat sink arranged in outer wall. The inner and outer fan wheels (3,5) are associated with the respective inner heat sink and outer heat sink. The fan wheels are supported on the drive shaft (7) which is rotated by a fan motor such that fan wheels are driven. A gear box is inserted between fan motor and drive shaft. The inner wall is made of stainless steel and outer wall is made of metal. The insulating layers (6) are formed between inner and outer walls.
