the coaxial titanium heat exchanger for heatpumps

Theory:

Coaxial heat exchanger have tube-in-tube and twisted inner tube designs. Rugged tube surface can maximize the overall heat trans

The resulting convoluted tube has increased heat transfer surface area per unit length yet still permits full flow of both water and refrigerant around its entire periphery for improved performance. Turbulence imparted by the convolutions to both the water and refrigerant flows further enhances the thermal performance, while inhibiting the accumulation of deposits on the surfaces. The net result is a highly effective, compact heat exchanger with superior anti-fouling characteristics.

The mainfeaturesof titanium corrugated tube heat exchanger:

1,High efficiency heat transfer:Because of using titanium corrugated tube, the flow channel continuously mutation, so that it always in a highly turbulent although the fluid velocity is very low. It is very difficult to become a laminar flow, and the main resistance for convective heat had being overcome. Simultaneously, the heat transfer are enhanced. so it has high efficiency heat transfer, more than the titanium plain tubes in 2 to 3 times.

2,Anti-fouling ability:The particles in the fluid are difficult to forming in the high turbulence in the flow channel. However, even with a small amount of scale formation on the wall, the turbulence of medium in the pipe, which is strongly erosion anti-fouling ability. Furthermore, it changes the stress of the different temperature between the inner tube and the outer tube, and the curvature of the thread pipe which has elastic characteristics has been changed lightly. That is why the threaded tube heat exchanger has the ability of antifouling and descaling.

3,Strong stress compensation ability:Because of the characteristics of thin-walled, elastic and structural shape threaded pipe, the curvature was changed lightly when the large temperature difference the inner tube and the outer tube to compensate and eliminate the thermal stress. Consequently to prevent the traditional tube heat exchanger to cracking efficiently.

4,With compact structure, small and light: The heat transfer coefficient of the threaded pipe heat exchanger is very high, and the required heat transfer areas are little, also with the small wall thickness, so the titanium corrugated tube heat exchanger has compact structure, small size and light weight.

Technical advantages and practical application:

The shell tube is stainless steel seamless tube and the inner tube is titanium threaded pipe. Different media in both tube achieve the effect of heat transfer by convection. Other manufacturers use plastic gasket flange to joint connection, which is complicated and costly. On the contrary, we adopt the design to the metal gasket will more efficient, durable as well as lower cost. We have tested the working pressure can reach 4MPa; Appropriate to the most of heat pumps. In practical applications, we have a model of air to water heat pump heater upstairs is using our titanium coaxial corrugated tube heat exchanger. It is made hot water to the staffs of our company to take shower. In addition, we can design and manufacture the right products according to your requirement.
