Micro-channel heat exchanger and separation plate connecting structure thereof

The invention discloses a micro-channel heat exchanger and a separation plate connecting structure thereof. The separation plate connecting structure of the micro-channel heat exchanger comprises a current collecting pipe and a separation plate; the current collecting pipe is provided with a first hole and a second hole for penetrating through the separation plate; the first hole is shorter than the second hole; and the separation plate is provided with a limiting structure clamped with the current collecting pipe in the first hole and for limiting movement of the separation plate from the first hole to the second hole. In the separation plate connecting structure of the micro-channel heat exchanger, as the limiting structure is arranged on the separation plate, the movement of the separation plate from the first hole to the second hole is stopped, the deviation of the separation plate from the current collecting pipe from the larger second hole is prevented, that is, the falling of the separation plate from
