Head or a follower for a shot of plate heat exchanger; heat exchanger plate and personnel who understands

摘要

In a plate heat exchanger of large dimensions the frame members, such as the head and follower, become very heavy and bulky so manufacture and handling becomes matters of difficulty. In accordance with the present invention a head (4) or follower (12) of a plate heat exchanger frame is made-up from separate slabs (5, 6, 7 or 13, 14, 15 respectively). A range of heat exchangers may then have common standard upper and lower slabs and either no intermediate slab or a selected one or more of a range of intermediate slabs.
