HCHex is a small tool designed to help you make all necessary calculations for demonstrating the thermal calculations for the helical coil exchanger design. To put it simply, the program can do all the sizing and thermal calculations in the design automatically and generate the summary with all the results at the same time.
The application can calculate unknown hot and cold side temperatures as well as the exit temperatures on both sides. In addition, the app can calculate the pressure drops for shell and tube sides, including the frictional, outlet, inlet and total drops. Other noteworthy calculations you can perform using this utility include unknown flow rate on either cold or hot side, vessel dimension and length, number of spiral turns for the helical tube as well as its length, area and heat load and the Nusselt number estimation.
The app allows you to add your own Nusselt correlation in three formats and lets you add your own number or a heat transfer coefficient if needed. The program comes with several databases, including one that can estimate the Physical properties of pure components for almost 1,500 fluids. The unit converter embedded can do 23 measurements units with 200 unit-conversion, whereas the results can be displayed in the charts.
Helical coil exchanger has shown significant improvements over the conventional heat exchangers in terms of mechanical design, cost reduction, thermal efficiency, and energy saving.
The increasing concern of the global warming has developed a strong need for more efficient heat exchangers.
Helical coil exchanger as the new heat exchanger type demonstrates more efficiency and lower fouling and corrosion phenomenon than the conventional ones.
Helical coil heat exchanger design has been very popular in recent years. In this study, a new design of helical coil heat exchanger with the ratio of spiral length to initial tube length of 1.5 is proposed.
The analytical solution of the Navier–Stokes equations are used to compute the hydrodynamic and thermal performance of the helical coil heat exchangers. On the basis of the design flow parameters and the coefficients of heat transfer, the optimal lengths of helical tube and spiral coil are also obtained. A numerical verification is performed and compared with the analytical solutions.
The fundamental behavior of helical coil exchangers is determined by solving the partial differential equations (PDEs) associated with the fluid dynamics and heat transfer.
The flow patterns and temperature distribution are obtained by solving the Navier–Stokes equations. The heat transfer is performed using the Fourier law and the boundary conditions.
A significant difference is observed in the effect of the heat transfer coefficient on the performance of the helical coil exchangers. The study on the effect of initial temperature difference on heat transfer coefficient shows that an increase in the initial temperature difference is conducive to improving the heat transfer performance of the helical coil exchangers.
The computational results are used to determine the optimal size of helical coil exchangers. The results obtained from the proposed model are compared with the data available in the literature and the results are found to be in good agreement with the reported data.
The purpose of this study is to develop a new technique for evaluating the performance of the induction heater in the RIG system. First, the behavior of the vessel in which the heater is installed is evaluated in terms of geometry. For this purpose, the correlations that relate the inside diameter, length and thermal properties of the vessel with the same diameter and length of the vessel (that is, the shell and the tube) in the case of the straight tube are extrapolated to the helical tube. On this basis, the shell coefficient can be determined and the thermal stability of the helical coil is evaluated as the temperature difference for the induction heating conditions.

As the need for higher heat exchanger efficiency arises, the concept of helical coil exchangers is being adopted to satisfy that need in many applications including hot water tanks, power boilers, kettles, or steam-turbines. With these applications, the heat exchangers may experience high and different temperatures on the hot and cold sides. Either can be the source of thermal stresses to the exchanger. Thermal stresses of the heat exchanger can then result in any of the following: noise, vibration and mechanical failure.
The helical coil exchanger design is a particular type of heat exchanger that involves a helical or spiral shape to the tubing or shell structure instead of just using plain tubes and shells. It is usually applied to colder heat transfer situations, such as heat engines, for example, power-generation where efficient heat transfer, a high coefficient of performance, and low pressure drop are highly desired. The coil-helix design also provides higher resistance to corrosion and better heat transfer performance. At the beginning of its development, the helical coil heat exchanger was sometimes mistaken for a particular type of fluid-piping, such as a double-wall spiral coil, but is not like that. There are many coils for a heat exchanger, and helix coils can be used in regular exchange piping as well as the shell side.
A helical coil exchanger is an ideal type of heat exchanger where the helix coils have a helical shape instead of helix coils. It provides a more compact design and may be used for a better heat transfer rate. This exchanger also allows the tubes to take the spiral shape in place of a straight tube or pipe. A helical coil can enhance the heat transfer coefficient in a shell-side by increasing surface area and decreasing the volume. In a helical coil exchanger, the helix coils maximize the surface area with the minimum volume of tubes and shell, which provides an effective heat transfer and pressure drop. The coils are helical, so there is an access of either side to the tubing or shell. This design allows the use of any fluid. Helical coil exchangers can find various industrial, laboratory, and research applications.
The helical coil exchanger design is also suitable for gas-to-fluid heat exchangers. Heat exchangers used for gas-to-fluid heat exchangers can include a helical coil exchanger. The helical coil exchanger is made to transfer heat to or from a gas. Helical coil exch
The Helical coil is a type of heat exchanger where the heat transfer is performed by a helical flow of a fluid that passes through its internal channels that are shaped as the helix. This design has certain advantages when compared to other heat exchangers like shell and tube and plate-and-frame. We take that advantage and use it to produce designs like other heat exchangers but without their disadvantages.
1. The helical coil exchanger design generates a strong flow that uses less pump energy.
2. The exchanger uses a spiral pattern for heat transfer. This helical flow has two main advantages:
a. It generates a strong flow and as the flow progresses, there is less pressure drop and maximum pressure recovery at the exchanger outlet. This property of a helical flow directly affects the pressure drop.
b. The exchanger can reduce the average Reynolds number. This reduces the frictional losses and increases the heat transfer efficiency.
3. The exchanger has a much better pressure recovery and lower pressure drop at the outlet than the shell and tube and plate and frame heat exchangers.
4. The exchanger has fewer tubes and they are of longer diameter. This reduces the pressure drop because of the increased length of the flow, which directly affects the pressure drop.
5. The exchanger uses a spiral pattern instead of a plate pattern. This directly affects the pressure drop because a plate is a continuous, thick surface, where as a spiral is a triangular pattern. This triangular pattern increases the specific heat transfer area.
6. The helical coil exchangers are more resistant to corrosion and can be designed for any operating conditions.
7. The helical coil exchangers are inexpensive to manufacture and have lower maintenance.
8. The helical coil exchangers have high reliability.
9. The helical coil exchangers are easily fabricated, which is economical.
10. The helical coil exchangers have similar size to the shell and tube heat exchangers.
11. The helical coil exchangers generate more comfort because of the smaller space they occupy.
12. The helical coil exchangers can reduce the pipe diameter by 50%. This means less pressure drop and less pump power consumption.
13. The helical coil exchangers can reduce the pump speed by half.
14. The helical coil exchangers can reduce the fluid viscosity by 15% – 40%. This translates to lower power consumption in operation and less lubrication needed.
