However, during actual bending, the compression amount of the inner fin part is usually smaller than the stretching amount of the outer fin part, that is, the bending center line is not located in the center of the fin width direction, but is biased towards the inner side of the bend, so It is easy to cause the outer fin part to be broken during bending, which affects the heat transfer performance and appearance of the heat exchanger

The invention discloses a heat exchanger bending protection device which comprises a plate-shaped flexible main body and a plurality of strip-shaped bulges; the strip-shaped bulges are arranged on the lower surface of the plate-shaped flexible main body and extend along the width direction of the plate-shaped flexible main body; and the strip-shaped bulges are arranged at intervals along the length direction of the plate-shaped flexible main body. The heat exchanger bending protection device provided by the invention can ensure that the deformations of fin parts of bent internal and external sides are the same when a heat exchanger is bent, therefore, fins can be avoided to be broken, the bent heat exchanger appearance and the heat exchanging performance are not influenced. The invention further provides a method for bending the heat exchanger by the bending protection device.
Description
technical field [0001] The invention relates to a heat exchanger bending protection device and a heat exchanger bending method. Background technique [0002] In order to improve applicability, traditional heat exchangers usually need to be bent, and some types of heat exchangers are bent along the axial direction of their headers. When bending, the fins between the heat exchange tubes are compressed in the height direction on the inner side of the bending centerline, and the outer side of the bending centerline is stretched in the height direction, in which the bending centerline The height of the fins does not change. However, in actual bending, the compression amount of the inner fin part is usually smaller than the stretching amount of the outer fin part, that is, the bending center line is not located in the center of the fin width direction, but is biased towards the inner side of the bend, so It is easy to cause the outer fin part to be broken during bending, which a...
