Abstract

An array of closely spaced solenoids may be employed for punching a plurality of holes in a substrate. Cooling is provided by air flow in the interstitial spaces between the solenoids. Cooling is improved by employing a turbulence deflector in each interstitial space, the turbulence deflector being a dowel pin with interrupted flats ground into it. Fig. 1 depicts a solenoid array 1 mounted on manifold 2 for punching holes in a substrate. Cooling is provided by air flow from manifold 2 through interstitial holes 3. Air flow from a hole presents laminar flow to the solenoid casing, which does not efficiently remove the heat. Cooling is improved by adding a turbulence deflector 4 to holes 3. Turbulence deflector 4 (Fig. 2) is a dowel pin with interrupted flats 5 ground therein.

Turbulence Deflector for Improved Solenoid Array Cooling

An array of closely spaced solenoids may be employed for punching a plurality of holes in a substrate. Cooling is provided by air flow in the interstitial spaces between the solenoids. Cooling is improved by employing a turbulence deflector in each interstitial space, the turbulence deflector being a dowel pin with interrupted flats ground into it. Fig. 1 depicts a solenoid array 1 mounted on manifold 2 for punching holes in a substrate. Cooling is provided by air flow from manifold 2 through interstitial holes 3. Air flow from a hole presents laminar flow to the solenoid casing, which does not efficiently remove the heat. Cooling is improved by adding a turbulence deflector 4 to holes 3. Turbulence deflector 4 (Fig. 2) is a dowel pin with interrupted flats 5 ground therein. The flats allow an air passage down to the manifold, and the interrupted grind creates a block to air flow which provides turbulence.
