Abstract

The invention relates to a casting type micro-channel compact type heat exchanger and a manufacturing method thereof. The heat exchanger is compact and reliable in structure and resistant to high temperature and high pressure and can effectively solve the thermal stress concentration problem of an existing heat exchanger. The heat exchanger comprises a heat exchanger shell, a first pipe plate, a second pipe plate, a third pipe plate, a fourth pipe plate, N first lining pipes, N second lining pipes, supporting pipe plates and a heat conduction core body. The heat exchanger shell comprises a straight pipe, a first Y-shaped pipe and a second Y-shaped pipe. The heat exchanger shell is filled with the heat conduction core body. The two supporting pipe plates are installed in the straight pipe in parallel. Gaps are formed between the edges of the supporting pipe plates and the inner walls of the straight pipes. The N first lining pipes and the N second lining pipes are arrayed in an S shapeor U shape in the heat exchanger shell, and therefore a cold and hot overflowing channel is formed, and the heat exchange aim is realized.

Description

technical field [0001] The invention belongs to the field of heat exchange, and in particular relates to a cast microchannel compact heat exchanger and a manufacturing method thereof. Background technique [0002] The supercritical carbon dioxide Brayton cycle is a new, efficient and safe energy cycle system, which is suitable for high-temperature gas-cooled reactor nuclear power plants, solar thermal power plants and other fields. The heat exchanger is one of the most important components in the supercritical carbon dioxide Brayton cycle. More than 50% of the heat in the entire cycle needs to be utilized through the heat exchanger. Its thermal hydraulic performance has an important impact on the efficiency of the entire cycle and the size of the system. . [0003] At present, the heat exchangers used in high-temperature and high-pressure conditions in nuclear power plant systems are mainly shell-and-tube heat exchangers. The existing shell-and-tube heat exchangers generall...
