The invention relates to the technical field of material surface treatment, in particular to a method for plating molybdenum on the surface of diamond powder through salt bath. By optimizing the components of the molten salt, the molten salt forms low-melting-point eutectic in the salt bath molybdenum plating process, molybdenum powder and carbon atoms on the surface of diamond are subjected to a chemical reaction at the low plating temperature to generate a uniformly-distributed molybdenum carbide layer, and heat damage to the diamond can be effectively avoided. Besides, the molten salt can form a high degree of superheat, diffusion of molybdenum atoms and chemical reaction of the molybdenum atoms and carbon atoms are facilitated, it can be guaranteed that the coating completely covers the surface of the diamond and is firmly combined, and it can be guaranteed that the thickness of the plating layer is controllable by regulating and controlling the plating time; the chlorate powder is non-toxic, harmful substances are not generated in the salt bath molybdenum plating process, the environment-friendly property is good, the chlorate powder can be used for industrial production, and the chlorate powder has wide application prospects and high engineering application value.

This utility model discloses an oblong, flooded evaporator for refrigeration, relating to the field of evaporator technology. It aims to solve the problem that increased refrigerant charge due to increased internal space in the evaporator shell leads to liquid carryover during compressor intake, significantly affecting unit stability. The key technical features include an evaporator shell with a support bracket, an air intake port, and an adjustment port for overall internal gas regulation fixedly connected from right to left at the upper end. A liquid inlet is fixedly connected at the lower end of the evaporator shell. The evaporator shell has a waist-shaped cross-section. A left water chamber is fixedly connected to the left side of the evaporator shell, and a right water chamber is fixedly connected to the right side. This design achieves a higher superheat at the top compared to traditional air conditioners, thus improving the overall energy efficiency of the unit.

The application provides a composite medium high-temperature heat pump circulation system and method. The composite medium high-temperature heat pump circulation system comprises: a regenerator connected with a separator; a primary compressor connected with a first outlet of the regenerator and used for preliminarily compressing a nitrogen-poor gas-phase working medium; an ejector, an injection inlet of which is connected with an outlet of the primary compressor, and a material inlet of the ejector is connected with a second outlet of the regenerator; a secondary compressor connected with an outlet of the ejector; and a condenser connected with an outlet of the secondary compressor and used for heat exchange, wherein high-temperature hot water or steam generated through heat exchange is directly delivered to a next device; and supercritical fluid discharged from the condenser is returned to the regenerator for heat exchange and then reenters the separator. By introducing appropriate nitrogen into carbon dioxide as an auxiliary component, the temperature rise amplitude of the mixed working medium in the compression process can be effectively improved.
