<p>A heat exchanger, comprising a flow collecting pipe (2); one side of the flow collecting pipe (2) is provided with a plurality of interfaces for inserting flat pipes (3); the flow collecting pipe (2) is also provided with a plate-shaped distributor (1) therein; a first opening (11) for distributing or collecting a medium is disposed on the plate of the plate-shaped distributor (1); the farther the longitudinal distance to the communication port (21) of the flow collecting pipe (2) in communication with an external medium pipe is, the larger the transverse size of the first opening (11) is; the plate-shaped distributor (1) can properly adjust the medium flow at different positions in the flow collecting pipe (2); on the flat pipes (3) close to or far from the communication port (21) of the flow collecting pipe (2), the plate-shaped distributor (1) can partially block the medium flow path, so as to prevent the medium just flowing into the flow collecting pipe or at the end of the flow collecting pipe (2) from directly flowing back into the flat pipes (3), thus solving the problem of dramatic change of flow rate on the flat pipes (3) closest to or farthest from the external medium communication port (21) of the flow collecting pipe (2), and facilitating the control of uniformly distributing medium flow among the flat pipes (3).</p> |
