This application relates to the field of air conditioner technology and discloses a microchannel heat exchanger and an air conditioner. The microchannel heat exchanger includes: multiple flat tubes, two manifolds, and at least one reversing valve. The reversing valve includes a valve body and a valve core. The valve core is configured to slide between a first position and a second position under the pressure of a fluid. When the valve core is in the first position, it blocks the first fluid inlet, and the second fluid inlet is connected to the fluid outlet. When the valve core is in the second position, it blocks the second fluid inlet, and the first fluid inlet is connected to the fluid outlet.
