Description

The invention relates to heat engineering, in particular, to the technology of manufacturing flat heat pipes.

The purpose of the invention is to expand the scope of application of the device by using it for sealing the Flat heat pipe after filling with coolant.

Fig. 1 schematically shows a device with an axial section; Fig. 2 is a diagram of the placement of dietary rations; nafig.3 - section of the heat pipe after sealing; fig 4 is the same, top view.

The device contains a punch 1 and a matrix 2, which are in contact with coaxially arranged annular projections 3 with flat walls 4 of the heat pipe 5. In the wall of the pipe 5,

the filling hole 6, and coaxially with it in the punch 1, is the hole 7, equipped with a fitting 8 for connection to the charging system with a coolant (coolant). The punch 1 on the outside of the protrusions 3 is provided with a sealing ring gasket 9, and the walls 4 of the pipe have discrete spaced spacers 10. The annular protrusions 3 on the punch 1 and the die 2 are connected by radial jumpers (not shown). After sealing, annular and radial grooves 11 and 12 respectively remain on the walls of pipe 5. Sealing gasket 9 serves to seal the opening 6 when filling the pipe with coolant. Matrix and panson are equipped with heaters 13 and 14.

The sealing of the heat pipe 5 is described as follows.

After filling the pipe 5 and dehydrating its cavity, squeeze the wall section 4 with the punch 1 and the die 2 when they are heated, while the extrusions 10 are dispensed. In the areas of the collar and radial protrusions of the punch and die, cold welding of the pipe walls and its sealing takes place.
