A spiral heat exchanger refers to a pair of flat surfaces that are coiled to form the two channels in a counter-flow arrangement. Each of the two channels has one long curved path. The main advantage of this device is its highly efficient use of space.
Design Features & Benefits
The spiral plate heat exchanger is made by rolling two long metal plates around a center core to form two concentric spiral flow passages, one for each fluid. The plate edges are welded shut so that each fluid stays within its own passage and there is no flow bypassing or intermixing. Channel plate width and spacing (gap between plates) are optimized for the specified duty, maximum heat transfer, and ease of access. The plate gap is maintained by welded spacer studs although some designs do not require them.
Due to its inherent circular design and large surface area to volume ratio, the spiral heat exchanger offers unique advantages over other types of heat exchangers like the shell and tube.
High Thermal Efficiency
Single and long curving flow passages with a uniform rectangular cross-section ensure superior flow distribution, intense turbulence, and high heat transfer coefficients (50-100% greater than shell & tubes).
Self-Cleaning Passages
The spiral's single-flow passages induce high shear rates that scrub away deposits as they form. This self-cleaning effect reduces fouling and makes spiral heat exchangers ideal for handling tough fluids such as process slurries, sludge, and media with suspended solids or fibers.
Countercurrent or Co-current
Spiral heat exchangers normally operate in true countercurrent flow for close approaches and temperature crosses. Occasionally a co-current flow design has major benefits, especially in cooling or heating fluids prone to gelation, burn-on, freezing or similar skin temperature related fouling.
Small Footprint & Easy Access
The spiral heat exchanger is compact and requires minimal space for installation and servicing. Removable covers provide easy access to interior heat transfer surfaces for field inspections, routine maintenance, or manual cleaning if required.
titanium plates are widely used in heat exchangers due to their excellent thermal conductivity, corrosion resistance, and high-temperature stability. A heat exchanger is a device that transfers heat between two fluids or materials, typically one fluid is heated while the other is cooled.
titanium plates can be used as the heat transfer medium in a heat exchanger, where they efficiently transfer heat while resisting corrosion and maintaining their structural integrity.

(1) the spiral wound tube heat exchanger is highly efficient and saves energy (steam). Internal unique reverse winding spiral coil structure, heat exchange in a current way, make fully condensing steam in the heat exchange tube bundle, do not need a second heat exchange, so it can save a lot of steam;
(2) spiral wound tube heat exchanger is stainless steel welding, it can bear high temperature and high pressure. Because the heat exchange tube bundle and shell are all made of stainless steel material, with uniform expansion coefficient, the maximum pressure is1.6 MPa, the highest heat-resistant is 400 â??,it will not cause deformation of the heat exchanger because of pressure and temperature; so there is no need to prepare the equipment to reduce the pressure and temperature. (3) its structure is compact, with small size, saving infrastructure investment; Lightweight and easy to install, the equipment can be connected directly to the pipe, reducing installation cost.
(4) the heat exchanger with Michael's (OWEN) turbulent buffeting frequency standard principle, the heat exchange tube bundle adopts the minimum clearance design, effectively eliminates the turbulent chattering phenomenon, prolongs the service life of the heat exchanger.
(5) the heat exchanger is low in scale with a low maintenance cost, with unique structure, unique surface treatment technology, and on both sides of the counterflow heat exchange medium, not only improving the integrated heat transfer coefficient but also with self-cleaning function and low scale tend. The method of chemical descaling can be used to clean the heat exchanger, which can save time, power, cost and effect.
Brief introduction:
Plate heat exchanger is a new type of high efficiency heat exchanger which is made of a series of corrugated metal sheets. A thin rectangular channel is formed between the plates, through which the heat exchange between liquid, liquid and vapor can be achieved.
Advantages of plate heat exchangers compared with tube heat exchangers:
1. Efficient and energy-saving: its heat transfer coefficient is 3000-4500kcal/m2* h, which is 3-5 times higher than that of shell-and-tube heat exchangers.
2. Compact structure: plate heat exchanger with the same area and heat exchange is only 1/5 of shell and tube heat exchanger.
3. Easy to clean, easy to assemble and disassemble.
4. Long service life: Plate heat exchanger is pressed by stainless steel or titanium alloy plates, which can resist various corrosion media, and the rubber pad can be replaced at will.
5. Strong adaptability: Plate heat exchanger plate is an independent component, can be added or subtracted according to the requirements, can be applied to a variety of different, process requirements.
6. No liquid crossing: The sealing groove of the plate heat exchanger is equipped with a discharge channel, and all kinds of medium will not be in collusion.
