The purpose of a heat exchanger header box is to act as a high pressure manifold that redistributes process fluid from a central source to a bundle of finned tubes where it can be cooled. Due to the lack of certified cover type header box design codes, industrial manufactures are left to develop their own in-house codes. This paper presents an
MECHANICAL DESIGN OF HEAT EXCHANGERSChannel partition plates. For exchangers with multiple tube passes, the channels are fitted with flat metal plates which divide the head into separate compartments. The thickness of these plates depends on channel diameter but is usually 9 to 16 mm for carbon and low alloy steels and 6 to 13 mm for the more expensive alloys.
Shell and tube exchanger. The shell and tube exchanger consists of four major parts:Front
US7967061B2 - Mini-channel heat exchanger header - Japanese Patent No. JP2002022313, Yasushi, discloses a parallel tube heat exchanger wherein refrigerant is supplied to the header through an inlet tube that extends along the axis of the header to
Shell and Tube Heat Exchangers Construction DetailsChannels or heads are required for shell-and-tube heat exchangers to contain the tube side fluid and to provide the desired flow path. Many types of channels are available. The three (3) letters TEMA designation is the standard method for identifying the type of channels and the type of shell of shell-and-tube heat exchangers.
At one or both ends of the plurality of tubes is a cover enclosing a space in fluid communication with the tubes, which is commonly referred to by a variety of terms such as a channel, bonnet,
China Channel Cover, Box, Tube Header of Heat Exchanger Channels are one of the most important components of the Tube Heat Exchangers. These parts are made from rolled plates, head, flange, nozzle and welded with ASME welding requirements. Note:Seal surface can be supplied with weld overlay inclusive ium, Hastelloy according to specifications.
Principal Types Of Construction - Heat ExchangersJun 06, 2021 · The tube-side header (or channel) may be welded to the tube sheet, as shown in Fig. 11-35 for type C and N heads. This type of construc tion is less costly than types B and M or A and L and still offers the advantage that tubes may be examined and replaced without disturbing the tube-side piping connections.
