Title:
SHELL-AND-TUBE HEAT EXCHANGER AND AIR CONDITIONING UNIT
Document Type and Number:
WIPO Patent Application WO/2024/021698
Kind Code:
A1
Abstract:
The present disclosure provides a shell-and-tube heat exchanger and an air conditioning unit. The shell-and-tube heat exchanger comprises a shell and, disposed in the shell, a flash evaporation structure and a liquid separation structure; a refrigerant inlet is formed in the shell; the liquid separation structure is arranged on a side of the flash evaporation structure away from the refrigerant inlet, and refrigerant entering the refrigerant inlet sequentially flows through the flash evaporation structure and the liquid separation structure. In the shell-and-tube heat exchanger and the air conditioning unit provided in the present disclosure, arranging the flash evaporation structure in the shell-and-tube heat exchanger increases the level of product integration, reduces the use of a connecting pipeline, and thus reduces the safety hazards of pipeline vibration and refrigerant leakage. Moreover, refrigerant throttled by the flash evaporation structure then being subjected to gas-liquid separation can improve liquid separation uniformity, and simultaneously reduces the problem of refrigerant splashing as a result of the refrigerant impacting an outer wall surface of a heat exchange pipe, enhancing the film distribution effect, and improving the heat transfer coefficient.
