Technical Field

[0001] The utility model relates to the technical field of plate heat exchanger maintenance, in particular to a device for repairing heat exchange fins of a plate heat exchanger. Background Art

[0002] The plate heat exchanger fin repair device is specifically designed to repair damaged fins in plate heat exchangers. This device effectively repairs fin perforations, thinning, and leaks that may occur during operation, thereby extending the service life of the heat exchanger and reducing the economic losses caused by fin damage. During repair, the fins must first be molded to restore their original shape and size.

[0003] When the molding machine presses the heat exchanger fin, due to the deformation problem of the heat exchanger fin, it is placed in the lower mold plate, and the four sides are not flat, and some parts are higher than the lower mold plate. During the closing process of the upper mold plate and the lower mold plate, the heat exchanger fin will be offset due to factors such as machine vibration, affecting the pressing effect. Therefore, it is necessary to provide a plate heat exchanger fin repair device to ensure that the heat exchanger fin will not be offset when the upper mold plate and the lower mold plate are closed. Utility Model Content

[0004] The purpose of the present utility model is to provide a device for repairing the heat exchanger fins of a plate heat exchanger, so as to solve the problem raised in the above-mentioned background technology that when the molding machine presses the heat exchanger fins, due to the deformation of the heat exchanger fins, the fins are placed in the lower mold plate, and the positions of the four sides are uneven, and some parts are higher than the lower mold plate. During the closing process of the upper mold plate and the lower mold plate, the heat exchanger fins will be offset due to factors such as machine vibration, thereby affecting the pressing effect.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

This setting can avoid direct contact between the upper mold plate and the inclined block, which may cause damage to the upper mold plate and increase production costs.

[0046] The main assembly also includes a bottom plate 12, support columns 13 and a top plate 14;

[0047] The bottom plate 12 is fixed to the middle of the upper surface of the equipment base 10. There are four support columns 13, the lower ends of which are fixed to the four corners of the upper surface of the bottom plate 12, and the top plate 14 is fixed to the upper ends of the support columns 13;
