The use of the vortex effect became relevant relatively "recently" - only 30 years ago, in the early 90s. Since then, this direction has been rapidly developing and one of its topical manifestations is the manufacture of vortex heat generators used for heating rooms.
What is a vortex heat generator?
The principle of operation of a vortex heat generator is based on a physical process in which high pressure is injected in a chamber with a liquid. Then gas bubbles are displaced, accompanied by an increase in temperature (indicators sometimes reach 1000 C0). If, after that, the liquid, heated to such a temperature, is sent to another chamber with a lower pressure, then the resulting thermal energy is released. That is why vortex generators are so practical - maximum heat at relatively low energy consumption.
Designs of various categories of vortex heat generators
The main differences between these devices are in their design features. Therefore, we will consider the designs of the three most popular types of vortex heat generators.
- Tangential. The main difference from the others is the presence of a special chamber in which the vortex effect occurs. Cold air is supplied to the chamber through one branch pipe, and hot air is supplied to the outside through the other. To create some pressure in the system, a braking device is installed at the inlet to the chamber, which prevents the fluid from moving further at a constant speed.
- Axial. In generators of this type, there is no camera, but its functions are performed by a special diaphragm with a large number of holes of a certain shape located throughout the body. The main disadvantage of such models is the presence of too many different structural parts, such as a heating chamber and a flow former.
- Active. Such heat generators have moving parts - activators, which create the same vortex effect. The problem of active type devices lies in the need for accurate calculation of both moving and stationary parts. But their efficiency is many times higher.
Any type of vortex heat generators has its own disadvantages and advantages, so the choice should be made based on the goals set.
Some subtleties of assembly
When assembling a vortex heat generator, it is necessary to purchase an electric motor, for example, an asynchronous type. It is better to choose engine power with a margin, since the amount of warm air emitted into the surrounding space directly depends on this parameter. You also need to find or make a camera with a metal disc inside.
The manufacturing and assembly process is simple: drill a series of blind holes in the disc and seal it in the chamber. Bring water to it through an ordinary pipe. The other pipe will be the outlet. Apply voltage to the electric motor through a switch or switch. Installation is over.
For greater efficiency, water must be supplied to the metal chamber by a pump - for the system to work properly, it needs to create some pressure in it.
