The invention discloses a high-temperature and low-temperature microchannel condenser. The structure of the high-temperature and low-temperature microchannel condenser comprises two core bodies, the two core bodies are the horizontal flow type high-temperature core body and the low-temperature core body, and the two core bodies are connected through a connection pipe. The horizontal flow type high-temperature core body is formed by at least six rows of cooling pipes which are connected in parallel. The low-temperature core body is composed of a snakelike coiler. The horizontal flow type high-temperature core body is provided with an inlet pipe. The low-temperature core body is provided with an outlet pipe. The high-temperature and low-temperature microchannel condenser is high in cooling efficiency, a refrigerant can conduct sufficient liquefying and cooling, and therefore the overall cooling effect of the microchannel condenser is improved.
