Abstract

The invention discloses a flat tube and fin clamping and pressing device, a manufacturing method and a micro-channel heat exchanger. The device comprises a first machine frame (11), a transfer platform assembly (12), a press machine assembly (13), a transfer module (14) and a second machine frame (15); the press machine assembly (13) is assembled on the first machine frame (11), and the transfer platform assembly (12) is used to control the transfer module (14) to move back and forth on the first machine frame (11) and the second machine frame (15); and the transfer platform assembly (12) is assembled on the transfer module (14) for pressing flat tubes and fins of various specifications together. According to the device, the flat tubes and the fins are fixed through pressing, so that the flat tubes and the fins are firmly connected, sufficient clamping pressure can be output, and overpressure is prevented from damaging strength of the fins.

Description

technical field [0001] The invention relates to the microchannel heat exchanger technology, in particular to a flat tube and fin clamping and pressing device, a manufacturing method and a microchannel heat exchanger. Background technique [0002] Microchannel heat exchangers have been widely used in small heat pumps, automotive air conditioners, household and central air conditioners in recent years because of their advantages such as high heat transfer coefficient, small size, less consumable materials, and no copper materials. In addition, the microchannel heat exchanger also has the advantages of less refrigerant injection, light weight, small wind resistance and high heat exchange efficiency. If it adopts an all-aluminum structure, it is easy to realize resource recovery. [0003] Usually, heat exchangers with channel equivalent diameters of 10 to 1000 μm are called microchannel heat exchangers, and the structure of microchannel heat exchangers includes flat tubes and he...
