Abstract

A fixture for measuring heating characteristics of modules is shown in the figure. The fixture as shown is formed of a clear plastic material, such as LUCITE*, and is adapted to support a plurality of modules, supply current to the modules, simulate air flow, and measure the heating characteristics of the modules.

Module Thermal Test Chamber

A fixture for measuring heating characteristics of modules is shown in the figure. The fixture as shown is formed of a clear plastic material, such as LUCITE*, and is adapted to support a plurality of modules, supply current to the modules, simulate air flow, and measure the heating characteristics of the modules.

The fixture is constructed to form a plurality of longitudinally extending channels, 10, 12, 14, 16 and 18 on one side and similar channels 20, 22, 24, 26 and 28 on the other side. A mounting block 30 is provided which can mount a module in each channel, one of which is shown at 32 mounted in channel 12. The mounting block 30 is formed of a good heat insulating material, such as balsa wood, and is provided with socket connections 34 at each location where modules are to be mounted. An electrical plug 36 and associated circuitry (not shown) are provided to supply electrical current to the module. Hinged doors 38 are provided front and back to allow access to the mounting block to insert and remove modules. openings 40 are provided in the structure at each channel adjacent the mounting block 36 which will allow for the insertion of thermocouples into the air flow, one of which is shown at 42.

The bottom of the fixture is provided with a perforated cover 44 which will receive a flow of air and channel the flow essentially laminarly in each channel.

To use the fixture, modules 32 are inserted at each location and powered. Air flo...
