4. The design that the drill way department of one side end of pressure manifold is equipped with the head is the technical characteristics of the utility model. The purpose of this design is: due to the arrangement of the seal heads, one end port of the collecting pipe is opened, and the other end port of the collecting pipe is closed, so that liquid can flow into or out conveniently due to the structural design.

The technical scheme is as follows: a harmonica tube type water-cooling plate comprises a water-cooling plate body, wherein a plurality of harmonica tubes are inserted between two collecting tubes in the water-cooling plate body; the orifices of the harmonica tube through holes in the collecting pipes are respectively turned inwards to form flanges, or the orifices of the harmonica tube through holes are turned inwards to form turned edges; the end heads of the two sides of the harmonica tube are respectively matched with the through holes of the harmonica tube corresponding to the collecting pipes in an inserting mode, and the tube wall at the end head of the harmonica tube is in contact with the turned edge or the curled edge corresponding to the through holes of the harmonica tube.

Compared with the prior art, the utility model has the advantages that firstly, the turnup or the turned edge is added in the harmonica tubular water-cooling plate, so that the contact area of the welding joint of the collecting pipe and the harmonica tube or the flat tube is increased, the bonding firmness between the collecting pipe and the harmonica tube or the flat tube is enhanced, and the service life of the harmonica tubular water-cooling plate is prolonged; and secondly, the mouth organ pipe type water cooling plate is provided with the flaring, so that the mouth organ pipe and the collecting pipe are welded to play a role in accurate positioning, and the production quality of the water cooling plate is improved.
