Second production of 12 coolingblocks is succesfull. See here for the Evaporator casting process document (pdf)
Production steps:

    The stainless steel mold is cleaned from aluminium (from the last meld) and the coolingtubes are placed. The mold is embrocated with microbraz (a stop off).
    1
    ACP5080 (AlMg4.5Mn) blocks are placed into the mold and stacked for placing into the vacuum melting chamber.
    2
    The vacuum melting chamber is closed by welding (Erno Roeland).
    3
    At a temperature of 700 oC degrees and vacuum is the AlMg4.5Mn melting around the coolingtubes. Luc van Diepen controlles the process.
    4
    After 10 minutes on 700 oC and cooling down (under Argon) to roomtemperature, the vacuum chamber is opened by a milling machine.

11 cooling blocks are successfull made in the productions jigs.

(september 30, 2004) * PROTOTYPE COOLINGBLOCK *

Due to the possibility of free forming the embedded tube this new cooling block made. This block has 5 separate cooling blocks cast to the pipe in 1 casting cycle. The separation shall eliminate the forces in the module occurred by the differences in CTE. The mounting interface is the same for both designs. The disadvantage of this cooling block is worse thermal performance as the strait version. Also handling seems less practical.

Manufacturing steps:
1) Cooling tube is bended in the right shape
2) Melting of the aluminium under vacuum, for perfect floating of the aluminum in the mould, together with the stainless steel cooling tube in a casting jig.
3) Solidifying under Argon to eliminate vapor bubbles in the aluminium cooling block.
4) Machining of the backside of the coolingblock to get is flat and so thin as posibble. The molded side don't need post-machining.

Optimal material is AL99.5 or AlMg4.5Mn.

process parameters:

  • Evacuate the vacuum chamber before heating
  • Setting the oven to be 700°C for 1 hour
  • After sensor in casting mould has reached 700°C, 1 Bar Argon will be inserted (oven time is approx. 30 minutes)
  • Solidifying is obtained with a closed oven
