Description

Technical Field

[0002] High temperature and high pressure rheometers are usually in a high temperature and high pressure working environment for a long time when in use, so a large amount of waste heat will be generated during operation. In order to avoid a large temperature rise in the mechanical parts around the high temperature environment of the rheometer, it is necessary to use a constant temperature oil to cool it, and then cool the oil through a cooling device to dissipate the heat to other media outside the system. Most existing oil cooling devices are integrated, which are large in size, noisy, and inconvenient for maintenance. The entire refrigerant circulation loop is installed indoors, so the cooling efficiency is low, and the condensation system is used to directly cool the oil. The oil flows in the cooling system. Since the oil is high temperature oil after coming out of the high temperature and high pressure rheometer, the solution damages the refrigeration system, and the deterioration of the high temperature oil is also easy to cause the refrigeration system to be blocked.
