Definitions

  • a collector for the deposition (if alloys from the vapour phase is described which includes a thick metal plate which has a first face and a second face opposite the first face; a plurality of heat sink members attached in efficient thermal contact with the said second face.
  • the heat sink members being provided with internal channels for the passage of coolant; and flexible connecting means connecting at least some of the channels to allow circulation of coolant through at least some of the heat sink members.
  • Embodiments of the present invention may permit a collector to have its temperature maintained at temperatures of the order of 300C by use of water as a coolant.
  • a temperature control device includes a body the temperature of which is to be controlled; a plurality of heat sink members attached in efficient thermal contact with the body, the heat sink members being provided with internal channels for the passage of a coolant; and flexible connecting means connecting at least some of the channels to allow circulation of coolant through at least some of the heat sink members and arranged to remain leak tight despite expansion or contraction of the apparatus due to heating.
  • Typical apparatus for the production of an alloy by deposition of its components from the vapour phase includes a heated sourcce means from which the constituents are evaporated, a temperature controllable collector, and a removable shutter interposed between the source and the collector so that the metal vapour only impinges upon the collector when desired, the whole being enclosed in a controllable vacuum or low pressure system.
  • All of the heat sink members may be on the same coolant circuit and preferably the coolant is water.
  • the collector assembly comprising the collector itself and the attached heat sink members and coolant circulating means are designed for a specific temperature or temperature range at the collector face by use of known information regarding thermal conductivity of the materials, coefficients of expansion and expected heat flux at the collecting surface.
  • the heat sink members are distributed to a predetermined pattern on the back of the collector so that the expected heat flux is transferred to the coolant, each heat sink member taking an appropriate quantity of heat.
  • a difficulty which arises is that under the influence of the temperature gradient across the collector the collector undergoes distortion and if removable heat sink members of a material different from the collector are used this distortion will tend to break the efficient thermal contact necessary for successful operation.
  • the heat sink members are preferably of a high thermally conductive material, for example copper, and in accordance with an aspect of the present invention the member, spacing and contact area of the heat sink members are selected so that the radii of curvature (r) of the collector and of the heat sink members caused by heat distortion at operating temperature are substantially the same as determined by the formula:
  • K thermal conductivity
  • a the coefficient of linear expansion
  • Q the heat flux per unit of contact area
  • the heat sink members are removably attached and in accordance with a further aspect of the present invention the heat sink members are attached to the collector by a bolt or like means of material having a lower coefficient of linear expansion than the material of the heat sink means so that as the temperature is raised the heat sink means is more firmly attached to the collector.
  • the material of the bolt must have a coefficient of linear expansion and a strength such that it does not break under the strain imposed upon it by such differential thermal expansion.
  • FIG. 1 is a general perspective view of a collector
  • the assembly includes a thick collector plate 10 of aluminium having a surface 1 l for the deposit of the alloy and on the opposite surface 12, are heat sink members 13.
  • the collector plate 10 is supported by a shaft 14 (the means of attachment of the shaft 14 to the collector 10 are not shown but are conventional).
  • Each heat sink member 13 comprises a lower copper block 15, a copper tube 16, an upper copper block 17 and a stainless steel water compartment 18. All of these parts are held on to the collector plate 10 by means of a mild steel bolt 19.
  • the shaft 14 is provided with a water distribution housing 20 and pipes 21, 22 and 26 are provided to circulate Water through the water compartments 18, each run of pipes being provided with a flexible vacuum seal
  • the collector 10 is also provided with a thermocouple 24 by which the temperature can be monitored and heaters 25 by which the collector can be heated.
  • thermocouple 24 by which the temperature can be monitored
  • heaters 25 by which the collector can be heated.
  • a similar circulation serves the other two heat sink members.
  • the electrical leads to the thermocouple 24 and heaters 25 and the water supply to and from the water distribution housing 20 are not shown but these are accommodated in conventional fashion on the shaft 14.
  • the heat sink member 13 is shown in section with the lower copper block 15, the copper tube 16, the upper copper block 17 and the stainless steel water compartment 18.
  • a mild steel bolt 19 fitted with a washer 30, is screwed into a mild steel bolt 31.
  • the bolt 31 is held in position in the collector plate 10 by means of an aluminium plug 32, consequently the mild steel bolt 19 maintaining the heat sink member 13 in contact with the collector plate 10.
  • the water compartment 18 is hollow and has an inlet tube 33 by which the cooling water is introduced into the compartment. the exit tube is not visible in this section.
  • the temperature of the collector face 11 is a function of the rate of heat removal and may be adjusted by changing the copper tube 16.
  • a material of different thermal conductivity than copper may also be substituted rather than altering the dimensions of tube 16.
  • a temperature controllable collector having a thick metal plate which has a first face adapted to receive deposited alloy and a second face opposite the first face;
  • heat sink members attached in efficient thermal contact with said second face, the heat sink members being provided with internal channels for the passage of coolant:
  • each heat sink member includes a replaceable member through which a major part of the heat flux flows in operation so that the rate of heat flow and hence the operating temperature may be altered by replacing said replaceable members with similar members of differing dimensions and/or differing thermally conductive properties.
  • connectmg means are arcuate pipes.
