The invention provides a fin unit, a heat exchange fin and a heat exchanger, and relates to the technical field of heat exchangers. Each fin unit comprises a first bottom plate, a second bottom plate, a first spoiler, a second spoiler, a third spoiler and a fourth spoiler; the first bottom plate, the first spoiler, the second spoiler and the second bottom plate are sequentially connected, the second bottom plate, the third spoiler, the fourth spoiler and the second bottom plate are sequentially connected, and projections of the second spoiler and the third spoiler on a first plane are arranged in a crossed mode. The inclination angle of at least one of the first spoiler, the second spoiler, the third spoiler and the fourth spoiler is smaller than that of the other spoilers, so that fluid can strongly flow on the spoilers with smaller inclination angles in the flowing process of the fluid in the heat exchange fins; therefore, the fluid can impact the tops and the bottoms of the fin units more strongly, and the heat exchange efficiency is improved.

The utility model relates to the technical field of heaters, in particular to a heat exchange structure of a heater. The flow channel comprises a first C-shaped structural part and a second C-shaped structural part which are connected, opposite channel grooves are formed in the first structural part and the second structural part respectively, the channel grooves in the first structural part and the second structural part form a double-layer flow channel, channel connectors are arranged at the upper end and the lower end in the second structural part respectively, and the two channel connectors are connected into the channel grooves of the second structural part respectively. The two channel connectors are connected; the device is formed by metal plates, production is simple and efficient, materials are evenly distributed, and compared with die casting of an old technology, the device is thin in material thickness, high in heat exchange efficiency, high in heat transmission speed, high in iron melting point, durable and low in production cost; according to the device, the double-layer flow channel is used, so that the temperature difference is naturally generated in the heat exchange process, the air flow is strong, the heat exchange distance of flue gas is long, and the heat utilization rate is high; when the device is used, combusted gas is separated from external air, waste gas is forcibly exhausted, and poisoning is avoided.

The present application relates to the technical field of battery cap manufacturing equipment, and discloses a cylindrical power lithium battery cap laser welding machine, including a clamping member, which is connected to a driving cylinder through a connecting arm, and the clamping member includes a clamping cylinder fixedly connected to the connecting arm, and the inner wall of the clamping cylinder near the upper and lower ends is connected to a connecting seat through a connecting rod, and one side of the connecting seat is connected to an expansion bladder, which is coaxial with the clamping cylinder, and is completely located in the welding line when the expansion bladder is in a contracted state, and can contact the inner wall of the clamping cylinder when the expansion state. The cylindrical power lithium battery cap laser welding machine uses the expansion of the expansion bladder to seal the end of the clamping cylinder, and the clamping cylinder is filled with protective gas. When the clamping cylinder presses the cap assembly, the expansion bladder contracts, and an upward or downward protective gas flow is formed in the clamping cylinder, isolating the air and will not change the cap position. At the same time, the time consumed to evacuate the air and the gas flow is short, thereby improving the welding efficiency.
