Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically a low-temperature composite evaporator. Background Technology

[0002] In modern industrial production, cold chain logistics, and food processing, low-temperature refrigeration technology is a key link in ensuring product quality and stable operation of processes. As a core component of the refrigeration system, the evaporator plays an important role in converting low-temperature, low-pressure liquid refrigerant into a gaseous state while absorbing external heat to achieve cooling. With the continuous improvement of refrigeration efficiency, equipment stability, and energy saving requirements in various industries, the performance of traditional evaporators can no longer meet the increasingly stringent demands. There is an urgent need to develop new evaporator structures to adapt to market changes and improve the overall efficiency of refrigeration systems.

[0003] Currently, most traditional evaporators on the market adopt a single heat transfer structure, which has a limited heat transfer area and low heat transfer efficiency, resulting in high energy consumption and slow cooling speed during the refrigeration process. Conventional finned evaporators are prone to contact thermal resistance in the connection between the fins and pipes, which reduces the heat conduction efficiency. In addition, traditional evaporators lack modularity and convenient maintenance in their structural design. Once a failure occurs, disassembly and repair are difficult, which not only consumes a lot of time and manpower costs, but may also cause production interruption due to downtime, resulting in significant economic losses. At the same time, traditional evaporators have insufficient protection performance and cannot resist corrosion and erosion under complex working conditions, which further shortens the service life of the equipment and cannot meet the long-term needs of modern industry for efficient and stable refrigeration equipment. Therefore, we propose a low-temperature composite evaporator. Utility Model Content

[0047] Working Principle: At the start of operation, low-temperature, low-pressure liquid refrigerant enters the conductive copper tube 7 through the refrigerant inlet 8. The conductive copper tube 7 is inserted inside the conductive tube 5, which is closely distributed at the front and back of the fixed plate 4 and connected to the connecting plate 3 at both ends, forming a stable heat transfer channel network. Simultaneously, the multiple conductive fins 6 fitted onto the conductive tube 5 greatly increase the heat transfer area and enhance heat exchange efficiency. As the liquid refrigerant flows within the conductive copper tube 7, it continuously absorbs heat transferred from the surrounding conductive tubes 5 and conductive fins 6, gradually evaporating into a gaseous state. During this process, because the back of the conductive fins 6 is tightly fitted to the fixed plate 4, and the conductive tubes 5 are inserted into the mounting holes 12 of the connecting plate 3, a highly efficient heat conduction path is formed, allowing the heat of the cooled medium to be quickly transferred to the surface of the conductive copper tube 7. As the refrigerant continuously absorbs heat and evaporates, the gaseous refrigerant finally exits from the refrigerant outlet. The fluid flows out of port 9 and enters the subsequent refrigeration cycle. The medium that needs to be cooled flows outside the evaporator. When it flows over the surface of the conductive fins 6 and conductive tubes 5, it transfers its own heat to the evaporator, thereby achieving cooling. The connecting plate 3 and the fixing plate 4 are connected by threads and fixed by bolts in the connecting hole 11, ensuring the stability of the structure. The protective shell 10 is installed on the outside of the connecting plate 3 by threads, which not only protects the internal components from external environmental corrosion, but also optimizes airflow organization and reduces heat loss. At the same time, the support plate 2 and the connecting plate 3 are fixed by the connecting threaded cylinder 13. The mounting plate 1 and the support plate 2 are connected by bolts using T-shaped blocks 16 and T-shaped grooves 15. The layered installation structure facilitates the installation, disassembly and maintenance of the equipment. In the entire operation of the low-temperature composite evaporator, through reasonable structural design and efficient heat exchange path planning, the refrigeration function can be achieved stably and efficiently.
