Low-temperature refrigerating semi-sealed compressor motor junction box configuration system

Abstract

The invention relates to a low-temperature refrigerating semi-sealed compressor motor junction box configuration system. The low-temperature refrigerating semi-sealed compressor motor junction box configuration system comprises a compressor cavity, a motor cavity and a junction box. The motor cavity is connected with the compressor cavity. The junction box is arranged at the position of the outerside of an exhaust hole opening of the compressor cavity, and the exhaust hole opening of the compressor cavity communicates with an exhaust channel. The exhaust channel and the junction box are of anintegral casting structure so that the junction box can be completely isolated from the compressor, high-temperature exhaust passing through the exhaust channel can heat the junction box, and the junction box is prevented from being frozen and frosted. Compared with a traditional technology, the junction box is effectively prevented from being frozen and frosted, meanwhile, energy is not additionally consumed, the lead safety is ensured, the system process is simplified, and a stable and safe design foundation is provided for a low-temperature refrigerating system and a semi-sealed compressor.

Description

technical field [0001] The invention relates to a low-temperature refrigeration semi-hermetic compressor motor junction box, in particular to a configuration system for the semi-hermetic compressor motor junction box in a low-temperature refrigeration system. Background technique [0002] Low-temperature refrigeration systems are widely used in refrigeration, food processing, medicine, and chemical industries to provide cooling for low-temperature environments below -35°C or even below -50°C. In a low-temperature refrigeration system, the compressor is its core component, and is often the most critical factor that determines the energy efficiency and stability of the refrigeration system. Due to the particularity of the refrigerant in the cryogenic system and the safety of the cryogenic system, the compressor of the cryogenic refrigeration system often adopts a semi-hermetic design, that is, the compressor and the motor are integrally connected and the whole machine is packa...
