Definitions

  • the present invention relates to a method of manufacturing a metal part, in particular a solid metal part, provided internally with a recessed part, in particular with a recessed part of small cross section and any profile, comprising a casting of metal around a tube surrounding said hollowed-out part made of the same metal as that which it is desired to pour, or in a metal having a melting temperature close to that of this metal, and the simultaneous passage through said tube a two-phase liquid-carrier gas coolant, in which a turbulent suspension of very fine droplets of liquid atomized in the carrier gas is introduced into said tube by one of its ends.
  • Such link discontinuities can cause significant and localized heating which is detrimental to the good performance of the metal part. Indeed, the differences in temperature between the overheated zones and the normally cooled zones can generate mechanical stresses and local flow which can increase the volume of the air-filled spaces, cause others, cause cracks which, developing , are likely to ultimately lead to the destruction of the metal part.
  • the process of the present invention it is advantageously possible to prevent the very fine droplets of liquid atomized in the carrier gas from agglomerating in order to maintain over the entire length of the tube an efficient and homogeneous dispersion of the liquid in the carrier gas and to conserve , and even increase, the efficiency of the heat exchanges between the metal tube and the two-phase cooling fluid, the cooling being all the better as the liquid droplets atomized in the carrier gas remain very fine and the flow in the metal tube remains turbulent.
  • the manufacturing process of the present invention can also make it possible to reduce the quantity of atomized liquid of the two-phase cooling fluid and to avoid very high flow rates in the metal tube as well as the dangers which are likely to result therefrom. .
  • It may consist, in another variant, of having, inside said metal tube, an axial cable extending over at least part of the length of the metal tube and carrying a multiplicity of substantially radial fins spaced in the direction longitudinal of the cable.
  • FIG. 1 shows an external view of a first embodiment, the metal tube in the form of a serpentine being embedded in a metallic mass represented in section,
  • an element generally identified by the reference 13 of relatively great length compared to the section of the metal tube 1, which has an axial rod 14 whose inner end 14a is free and whose outer end 14b is carried by a radial plate 15 which is provided with three large longitudinal passages 16a, 16b and 16c and whose periphery is inserted between the end of the branch 2 of the metal tube l and a spacer 12a which is at its other end bearing on the diaphragm 12.
  • the two-phase cooling fluid generated by the atomization device 5 is introduced into the metal tube 1 by its end 2a.
