STRUCTURE AND ADVANTAGES OF TUBULAR HEAT EXCHANGER
Structure of Murphy tubular heat exchanger:
Winding shell and tube heat exchanger is the core and outer cylinder of the space between the pipe directly according to the helix winding alternately to form, shape and adjacent two layers spiral screw direction of the pipe on the contrary, this time also will use a certain shape of distance to keep a certain distance. Coil winding pipe shell and tube heat exchanger equipment design can be used in a single winding, also can use two or more root compound after winding together.
The tube of the winding tube heat exchanger can pass through a single channel type wound tube heat exchanger. Of course, the equipment will be passed through several different media, and each media will be through the heat pipe are gathered in their respective plates, forming a multi-channel wound tubular heat exchanger; The heat exchanger equipment is suitable for the occasions where various media are processed simultaneously, large heat transfer is required under small temperature difference and the operating pressure of medium in the tube is high, such as the heat exchange equipment used in the low temperature process such as oxygen production.
Advantages of Murphy tubular heat exchanger:
The heat exchanger is compact in structure and the heat transfer area per unit volume is large. For the pipe diameter of 8~12mm, the heat transfer area per cubic meter volume can reach 100~170 square meters; After the application, the heat transfer of a variety of media can be carried out simultaneously. The high operating pressure inside the tube can reach more than 2000 MPa.
The heat expansion on the heat pipe in the winding tube heat exchanger equipment should be paid attention to compensate by itself. After that, it is quite easy to realize the large-scale development in terms of the equipment of wound tube heat exchanger.
Finally, we should pay attention to, about the coil of shell and tube heat exchanger equipment applicable temperature range is very wide, can adapt to thermal shock and thermal stress elimination itself, has a high compactness, and because of their special structure, also will make the fully developed flow field, there is no flow dead zone, in particular, by setting up more shares in the shell side of the (single), and passes to within a device to satisfy more fluid and heat transfer.
