ABSTRACT:
A device is provided for direct cooling of thick essentially horizontal wall members which are charged with different temperatures and possibly different pressures on their upper and lower sides, such as for cooling a heat exchanger tube sheet. Cooling of the wall member or component from the "cold side" is afford by closed end bores formed in the wall member which bores are open on the "cold side" and closed on the "hot side". Each closed end bore has a tube projecting from the "cold side" of the wall member and extending into the bore with its end within the bore located adjacent the closed end of the bore. The diameter of the tube is smaller than the diameter of the bore so that flow through the tube into the bore can reverse direction at the closed end and flow through the space between the tube and the bore.
