Title: Air-conditioning body prodn. method - uses medium under pressure to distort outer plates outwards where not welded to inner plates
Inventor: RAUH WERNER
IPC: B21D53/04
Filed: 1980-02-08
Abstract: The production method is for an air-conditioning body, for heating or cooling, using flat thin plates. Three flat plates are placed one on top of the other and in line, and are then fixed together at predetermined points, typically by spot-welding. They are then sealed together by welding along their outside edges. A medium under pressure is then introduced into the intervening spaces between the middle plate and the two outer ones, thus distorting the latter outwards where they are not fixed to the middle one. When distortion is complete, the medium is discharged again.

Patent DE-3030497-A1 (DE)
Inventor: ZEITLER MARTIN
IPC: B22D30/00
Filed: 1980-08-12
Abstract: The method and device for the periodic cooling of castings by means of a coolant on a conveyor track between a knock-out station (2) and a knock-off channel comprises a number of spraying devices (10) which are, for example, arranged above the conveying device. The castings are transported in baskets (1), for example, and subjected at intervals to jets of water and/or air. Between the spraying points, the stored heat can escape from the castings. When the castings arrive at the knock-off channel, they have cooled to such an extent that there are no heat problems as regards the manual processing of the castings. If water alone is used as the coolant, normal tap water can be used. In this case, the method and device are extremely inexpensive when compared with fan and air cooling. <IMAGE>
