Product Description
High exchange efficiency Volume type Heat Exchanger,The series of heat exchanger bearing selection according to the standard, three bearings, a fixed bearing, two for the activities of bearing. The anchor of the movable bearing is made of double nuts. The first nut is tightened by tightening a small gasket and then backward. Then the nut is locked with the second nut so that the bearing can slide freely on the foundation.
How it works?
There are four primary classifications of heat exchangers according to their flow arrangement. In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side. Incounter-flow heat exchangers the fluids enter the exchanger from opposite ends. The counter current design is the most efficient, in that it can transfer the most heat from the heat (transfer) medium due to the fact that the average temperature difference along any unit length is greater. See countercurrent exchange. In a cross-flow heat exchanger, the fluids travel roughly perpendicular to one another through the exchanger.
For efficiency, heat exchangers are designed to maximize the surface area of the wall between the two fluids, while minimizing resistance to fluid flow through the exchanger. The exchanger's performance can also be affected by the addition of fins or corrugations in one or both directions, which increase surface area and may channel fluid flow or induce turbulence.
The driving temperature across the heat transfer surface varies with position, but an appropriate mean temperature can be defined. In most simple systems this is the "log mean temperature difference" (LMTD). Sometimes direct knowledge of the isLMTD) not available and the NTU method is used.
