Still refer to <FIG>. To form the plurality of separation cavities <NUM> of the valve core <NUM>, the valve core <NUM> may include a plurality of separation plates. The plurality of separation plates include a first separation plate <NUM> and a second separation plate <NUM>. The first separation plate <NUM> is perpendicular to the axial direction A of the valve core, the second separation plate <NUM> is parallel to the axial direction A of the valve core, and the plurality of separation plates form the plurality of separation cavities <NUM>. In a specific embodiment, the first separation plate <NUM> and the second separation plate <NUM> may be arranged based on a requirement, to form different layouts of the separation cavities <NUM>, so as to implement the multi-port valve having different shunting manners.

In a specific embodiment, the mounting cavity <NUM> is a cylindrical mounting cavity <NUM>, the valve core <NUM> is a cylindrical valve core <NUM>, and the valve core <NUM> and the mounting cavity <NUM> are mounted in a coaxial manner. The valve core <NUM> is mounted in the mounting cavity <NUM> of the valve body <NUM>, and may circumferentially rotate in the mounting cavity <NUM>. Specifically, the multi-port valve may further include a driver. The driver is connected to the valve core <NUM>, and is configured to drive the valve core <NUM> to rotate by a specified angle in the mounting cavity <NUM> of the valve body <NUM>. When the valve core <NUM> rotates to a specified position, at least two inner ports <NUM> communicate with one separation cavity <NUM>, so that the inner ports <NUM> communicating with the separation cavity <NUM> communicate with each other. The valve core <NUM> is controlled to rotate to different positions, so that different inner ports <NUM> can communicate with each other, to change a communication solution of the multi-port valve.

In a specific embodiment, the body <NUM> and the block-shaped additional portion <NUM> may be of an integrally formed structure. For example, if the valve body <NUM> is a valve body <NUM> made of a plastic material, the valve body <NUM> that is of the integrally formed structure may be prepared by using an injection molding process; or if the valve body <NUM> is a valve body <NUM> made of a metal material, the valve body <NUM> that is of the integrally formed structure may be prepared by using a casting process.
