Abstract

The invention discloses an ultralow temperature ice trough, belonging to the low temperature test devices. The structure of the ice trough adopts the two-stage cascade compressor refrigerating technology. A refrigerant of a first-stage compressor of a first-stage refrigerating system is condensed by a first-stage condenser, is throttled by a throttling device and then enters a telescopic heat exchanger to be evaporated to cool a second-stage refrigerating system. After a refrigerant of a second-stage compressor of a second-stage refrigerating system is throttled by an electronic expansion valve, a low temperature refrigerant enters an evaporator to be evaporated to cool cooling media in an ice trough vessel. When the temperature in the ice trough vessel approaches the set temperature, a bypass electronic expansion valve regulates cooling capacity in accordance with the instruction of a single chip to maintain the temperature in the ice trough vessel. Compared with the prior art, the ultralow temperature ice trough of the invention has the characteristics of ultralow test temperature, wide applicable range, high temperance controlling precision and low energy consumption, etc.

Description

technical field [0001] The invention relates to a low-temperature test device, in particular to an ultra-low temperature ice tank. Background technique [0002] The low-temperature ice tank is a device used to test the low-temperature physical properties of various materials. Various substances and materials will exhibit different temperature characteristics at different temperatures. Through the low temperature physical performance test, we can obtain the different physical properties of various substances and materials at different low temperatures, so as to determine the suitability of each material and material. domain and environment. The low-temperature performance characteristics tested include many aspects, such as the detection of low-temperature brittleness of raw materials. The determination of low-temperature brittleness is indispensable in both scientific research and manufacturing. [0003] Accurate temperature control is the basic requirement for experimenta...
