ABSTRACT:
A specimens rotating device including a cooling source located in the central portion of a rotary plate, and a plurality of specimens arranged in the peripheral portion of the rotary plate in a manner to surround the cooling source. A plurality of heat pipes are arranged between the cooling source and the specimens so that each heat pipe is secured at one end to the cooling source and at the other end to one of the specimens. Each heat pipe has a working fluid sealed therein and its one end is exposed in a cooling fluid in a channel in the cooling source. Upon rotation of the rotary plate, the specimens are rotated along with the rotary plate, and the working fluid in the heat pipes is shifted toward the specimens. The working fluid absorbs heat from the specimens and evaporates into vapor which quickly returns to the cooling source due to the difference in vapor pressure to condense into condensate by releasing the latent heat of evaporation into the cooling source which constantly receives a fresh supply of cooling fluid, to enable the heat from the specimens to be effectively released to outside.
