Abstract

The invention provides a flat tube and a heat exchanger, and relates to the technical field of heat exchange. The flat pipe comprises a pipe body, a plurality of deformation parts and a reinforcing part; the multiple deformation parts are arranged in the pipe body at intervals so as to divide the interior of the pipe body into multiple channels, and the deformation parts are used for allowing the pipe body to deform and limiting the maximum deformation amount of the pipe body; the reinforcing part is connected between the inner wall of the pipe body and the deformation part, and the reinforcing part is configured to allow the pipe body and the deformation part to deform synchronously. The interior of the pipe body is divided into the multiple channels by the multiple deformation parts, equivalently, the pipe body and the multiple deformation parts jointly form multiple small-pipe-diameter heat exchange pipes, the flowing resistance of refrigerants in the flat pipe can be reduced, and the situation that the pressure drop of a heat exchanger using the flat pipe is too large is avoided. A flow dividing head assembly and a flute pipe assembly do not need to be arranged between the channels for flow dividing, under the condition of the same refrigerant flow and mass flow, the flow dividing number is greatly reduced, the flow dividing structure is correspondingly simple, and therefore the manufacturing cost of the heat exchanger is reduced.

Description

technical field [0001] The present application relates to the technical field of heat exchange, in particular, to a flat tube and a heat exchanger. Background technique [0002] Finned heat exchangers are widely used due to their advantages of high heat exchange efficiency, compact structure and low manufacturing cost. The existing large-scale finned heat exchangers use small-diameter heat-exchange tubes with low cost to divide the refrigerant flow, but the internal refrigerant flow resistance of the small-diameter heat-exchange tubes is large, and it will cause the same mass flow rate. The number of flow paths is more than that of large-diameter heat exchange tubes, resulting in more splitter assemblies and piccolo assemblies, resulting in a significant increase in cost. Contents of the invention [0003] The embodiment of the present application provides a flat tube and a heat exchanger to improve the problem of high production cost of the existing heat exchanger.
