Abstract

The invention provides a low-temperature cooling and pressing device, comprising an upper cooling rod (7), a sample chamber (6) and a lower cooling rod (13) connected in sequence, and the sample chamber (6) is sleeved on the upper cooling rod (7) Outside the lower end and the upper end of the lower cooling rod (13), the upper cooling rod (7) is connected with an upper cooling chamber (10) that can cool the upper cooling rod (7), and the lower cooling rod (13) is connected with a cooling chamber that can cool the lower rod (13). The lower cooling chamber (15) in which the rod (13) cools down, and the low-temperature cooling pressure applying device also includes a pressurizing assembly, which can drive the lower cooling rod (13) to move toward the upper cooling rod (7) and squeeze the upper cooling rod (7). Cooling specimen (30) between cooling rod (7) and lower cooling rod (13). The low-temperature cooling and pressing device can not only realize fast cooling and applying pressure to the sample at the same time, but also can adjust the temperature and pressure in a wide range.

Description

Technical field [0001] The invention relates to an experimental instrument, in particular to a low-temperature cooling and pressing device. Background technique [0002] In scientific experiments, it is often necessary to cool the experimental sample to a lower temperature (such as below minus 100 degrees) and apply a certain pressure to the sample under low temperature conditions to change its properties. Conventional cooling equipment is often difficult to meet this demand. First of all, for devices and equipment that use liquid helium or liquid nitrogen as a refrigerant, they can often only provide a cooling environment and cannot achieve a pressurization function. In order to achieve low-temperature pressure, the sample is usually cooled to a certain temperature and then taken out, and the sample is pressurized in a room temperature environment. Although the heat transfer between the sample and the environment is a relatively slow process, if the action is fast, the entire ...
