High Flux Tube Heat Exchanger

High Flux Tube Heat Exchanger

High flux tube is bare tube evenly coated with a thin layer porous metal with multiple micro pores and interconnected tunnels. Surface porous coat not only increases heat transfer area, but also forms innumerable nucleation site to largely increase nucleation rate. Interconnected pores can also agitate local liquid during bubbling process, further increasing heat transfer coefficient outside tube. With synergy of many enhancements, heat transfer efficiency is greatly improved.

Features

Compared to bare tube, heat transfer area can be reduced by 27.5%.

Equipment operation capacity can be increased by 20%.

Total heat transfer coefficient is increased by 89%.

Boiling can be achieved by lower temperature difference. The requirement of heat source temperature is decreased with outstanding energy conservation effect.

Application

Widely used for reboiler, evaporator, condenser and so on when there is phase transition.

Tube Specs

Diameter: ф12～ф60 mm

Coat Thickness: 0.13～0.5 mm

Material: CS, SS, Cu and Cu Alloy, Ti and Ti Alloy, Ni alloy etc.

What is tube sheet layout?

What is tube sheet layout? A tube sheet is a component used in shell and tube heat exchangers and other types of heat transfer equipment. It is a flat plate with holes drilled in it, through which tubes are inserted and secured. The tube sheet serves as a barrier between the two fluids, allowing heat to be transferred from one to the other. The layout of the tube sheet depends on the design of the heat exchanger, which includes the number of tubes, the size of the tubes, and the spacing between the tubes. The layout is typically determined using computer-aided design (CAD) software, which can optimize the placement of the tubes to achieve the desired heat transfer performance. In general, the tubes are arranged in a triangular or square pattern on the tube sheet. The triangular pattern is often preferred because it provides better support for the tubes and reduces the risk of vibration and damage. The spacing between the tubes is also important, as it affects the flow rate and pressure

1. What is a finned tube bundle? Finned tube bundle composed of multiple finned tubes arranged according to certain rules is called finned tube bundle. A finned tube heat exchanger can be composed of one or more finned tube bundles. 2. What is the composition of the finned tube bundle? Finned tube (multiple tubes): basic element of heat transfer. Tube box (header) or tube plate: the header, elbow or steel plate connecting the two ends of the fin tube. When the finned tube is connected with the header or tube sheet, the spacing between the finned tubes is fixed, and the tube box forms a continuous flow channel for the fluid in the tube. Frame: support and fix the whole finned tube bundle. 3. Finned tube bundle arrangement? In a finned tubes bundle , the selection of fin tube arrangement is crucial. There are two types of arrangement: staggered and sequential. The so-called staggered arrangement refers to the cross arrangement of pipes in the air flow direction, while the in-line arran

What is heat exchange tube sheet?

What is heat exchange tube sheet? A heat exchange tube sheet is a component used in heat exchangers, which are devices that transfer heat from one fluid to another. The tube sheet is typically a flat, circular plate that separates the two fluid streams and contains holes through which the heat exchange tubes pass. The tubes are typically sealed into the tube sheet by welding or expansion, and the sheet is often made of materials such as carbon steel, stainless steel, or titanium. The purpose of the tube sheet is to provide a rigid support structure for the heat exchange tubes and to ensure that the tubes are properly aligned and spaced for efficient heat transfer. The tube sheet also serves to contain the fluid streams and prevent them from mixing, which could reduce the efficiency of the heat exchange process. Tube sheets can be designed for various types of heat exchangers, such as shell and tube, double pipe, and plate heat exchangers. The design of the tube sheet is typically based
