The invention relates to the technical field of heat collection and heat exchange, and discloses a thermal electron enhanced heat exchange device, a heat exchange system and a heat exchange method. The thermal electron enhanced heat exchange device includes a thermal electron heat transfer layer and a high-temperature heat source layer, wherein the thermal electron heat transfer layer includes a high-temperature cathode layer, a vacuum spacer layer, and a low-temperature anode layer in sequence from outside to inside, and the inner space of the low-temperature anode layer forms It is a low-temperature medium channel. The high-temperature cathode layer overflows hot electrons at high temperature, and the hot electrons take away part of the heat from the high-temperature cathode layer and transfer it to the low-temperature anode layer. The heated low-temperature anode layer exchanges heat with the low-temperature medium circulating in the low-temperature medium channel. The thermal electron enhanced heat exchange device provided by the present invention has a simple and compact structure, does not need to be additionally provided with a low-temperature medium circulation system, and has high safety and good reliability. In addition, the dual superposition of thermal electron heat transfer and radiation heat transfer is used to effectively improve the heat transfer efficiency and meet the heat transfer requirements in high temperature environments.

An on-off type lock and a key. The lock comprises an on-off type lock cylinder, a transmission mechanism and a lock sleeve (9); the key (1) is matched with the lock cylinder; the transmission mechanism comprises an inner sleeve (8), a lifting pin (71), a limiting pin (72) and an on-off pin (6); the lock cylinder rotates to form an on-off through groove (200), the lower part of the on-off pin (6) enters the on-off through groove (200) after the on-off pin (6) is extruded by the lifting pin (71), and the upper part of the on-off pin (6) is located in an on-off pin strip-shaped hole (81) of the inner sleeve (8), so that linkage unlocking between the lock cylinder and the inner sleeve (8) is realized; and after the lock cylinder rotates reversely and is locked, the limiting pin (72) limits the inner sleeve (8) from continuously rotating, the lock cylinder continues rotating reversely to extrude the lower part of the on-off pin (6) into the on-off pin strip-shaped hole (81), and the upper part of the on-off pin (6) enters a groove of the lock sleeve (9), so that linkage between the lock cylinder and the inner sleeve (8) is removed.
