Description

Coiled tube for boiler hot water {omitted}

The present invention relates to a heat exchanger coil tube for boiler hot water, and in order to supply hot water necessary for living such as kitchen and bath water, the inner and outer circumferential surfaces of the coil tube are made of a simple round tube in the form of a simple round tube, and the nose The inner and outer circumferential surface of the coherent inner and outer circumferential surface with a constant width and size, and the inner and outer concave surface, and the inner and outer concave surface to form a continuous wave form surface, the inner projection surface and inner surface in the hot water flow inside the coil pipe Vortex phenomena caused by the indentation surface cause rupture of the boundary membrane, increase of heat transfer area, and increase hot water temperature by collision and friction of water molecules to maximize thermal efficiency. It does not remain.

The coil pipe for hot water mainly used until now was a cylindrical tube of simple structure in which both the inner and outer circumferential surfaces were composed of both smooth surfaces. Therefore, the water in the center of the tube was not affected by the hot inner wall and could not maximize the role of the heat exchanger as a flow. When the flow rate of the same temperature flows, the heat exchange ability of the diamond tube and the general tube is excellent in the heat exchange ability of the diamond tube, leading to energy saving, and various foreign substances sucked into the hot water after a long period of time on the smooth inner peripheral surface. When scales are attached to the scales, they are wrapped. The water flows smoothly on the smooth inner circumferential surface, so that it cannot be removed at all.

The problem to be solved in the present invention is as follows.

As described above, the strength of the existing hot water coil pipe raised in the background, that is, the inner / outer circumferential surface of a simple circular tube composed of smooth surfaces, can achieve strength reinforcement, and at the same time, It is to prevent vortex phenomena to occur so that the boundary membrane is destroyed to obtain the maximum thermal efficiency.

The problem solving means of the present invention is formed on the outer circumferential surface of the hot water coil pipe 10 by diagonally intersecting the outer groove surface 12 at a predetermined width and intervals soaring gently between the crossed outer groove surface 12 The outer fusion surface 11 is molded and a smooth outer circumferential surface is formed, and the inner surface of the coil tube for hot water corresponds to the inner protrusion surface 12a and the outer fusion surface 11 corresponding to the outer groove surface 12. The inner concave surface 11a is formed to form an inner circumferential surface that causes vortex flow of hot water, respectively.

The present invention escapes from the simple configuration of the inner / outer peripheral surface of the hot water coil tube made of a smooth surface as a whole to maintain the shape of the circular tube intact the outer melt surface of the inner / outer peripheral surface of the hot water coil pipe 10 of a certain width and size (11) and mechanical improvement to allow the outer circumferential surface of which the outer recessed surface 12 is continuously arranged and the inner circumferential surface of which the inner recessed surface 11a and the inner protruding surface 12a facing each other are formed to correspond to each other. It is a structure.

Therefore, the hot water coil pipe 10 of the present invention is secured by the outer eluting surface 11 having a dome structure with a diagonally rising surface along with the diagonal outer groove surface 12 intersecting. Such a dome structure is a general-purpose technology well known in the construction field, and the resistance to external shock is greatly improved.

In the present invention, such a mechanical structure is applied to the coil pipe for hot water so that an outer circumferential surface having an outer groove surface 12 and a gentle outer eluting surface 11 is formed in the hot water pipe 10 having a circular cross section. Strength preservation against the external pressure while maintaining the circular preservation of the coiled tube 10 for hot water while providing a concave to extend its commercial life.

The outer eluting surface 11 is the same as the above description that the outer surface having a diamond shape is formed by the outer groove surface 12 crosswise formed in a diagonal direction, the upper surface of which has a dome phenomenon that rises gently.

Therefore, the dome-shaped mechanical structure by the outer fusion surface 11 ingot outer groove surface 12 enhances the strength reinforcement effect against bending or sinking in the external impact. In addition, in the flow of hot water through the inside of the hot water coil pipe 10, continuous vortices of hot water are generated on the inner circumferential wave surface by the inner protruding surface 12a and the inner concave surface 11a, thereby destroying the boundary membrane and conducting heat transfer. By increasing the area and the collision and friction of water molecules due to the vortex, the temperature of the hot water is further increased to provide the effect of maximizing thermal efficiency, and the continuous blow due to the vortex of the hot water acts on the inner wall of the hot water coil pipe 10. When it is wet on the inner wall of the coil pipe for hot water, it provides an effect of preventing the scale from being stuck or remaining attached.

The present invention achieves the strength reinforcement to solve the vulnerability to the impact of a simple circular tube consisting of a flat inner / outer peripheral surface as described above while at the same time vortex phenomenon in the hot water flow inside the tube to obtain the maximum thermal efficiency Its purpose is to make it possible to prevent the scales from sticking or remaining on the inner wall of the pipe.

Detailed description of the embodiments of the present invention for achieving the above object will be described below with reference to FIGS. 1, 2 and 3.

In the hot water coil pipe 10 for supplying hot water required for the home, the outer circumferential surface 12 of the hot water coil pipe is formed at a predetermined width and at intervals to form a diagonally replaced outer groove surface 12 to be replaced with each other. The outer eluting surface 11 which rises gently between the two) is molded to form a smooth outer circumferential surface, and the outer circumferential surface 12 is formed on the inner circumferential surface of the hot water coil pipe 10 to cause vortex flow of hot water. It is a coiled tube for hot water characterized in that the inner circumferential upper surface is formed.

In the present invention, as shown in Figs. 1 and 2, the above-described mechanical structure is applied to the coil pipe 10 for hot water having a circular cross section, and the outer groove surface 12 and the outer outer eluting surface 11 are angled to the outer circumference. By forming the wavy surface is to strengthen the strength to effectively counter the internal pressure, including the external pressure bar,

The outer eluting surface 11 has a dome shape in which its top surface rises gently while maintaining its diamond shape by the outer groove surface 12 intersecting in a diagonal direction. The dome-shaped mechanical structure by (11) and the outer groove surface (12) maintains the circular shape of the hot water coil (10) for a long time while responding not to bend or sink easily even when an external impact is applied.

In particular, when the boiler tube of a large boiler such as industrial or business is made of diamond-shaped steel pipe, the thermal efficiency is maximized, and it responds to the pressure higher than the general tube, and it is a significant energy saving. Usually, alban spiral steel pipes are used in heat exchangers such as industrial boilers. Bonded diamond steel pipes are much better in heat dissipation than general spiral steel pipes and will be widely used as industrial boiler tube tubes. In addition, in the hot water flow inside the hot water coil pipe 10, as shown in FIG. 3, the vortex of the hot water is continuously generated on the inner circumferential surface formed by the inner protruding surface 12a and the inner concave surface 11a. The impact of water molecules and frictional effects raises the temperature of the hot water further, thereby maximizing the thermal efficiency.As a result of the blow due to the hot water vortex, it prevents scales such as foreign substances from sticking to the inner wall of the hot water coil pipe and sticks residues. Done.

When the pipe structure of the present invention is used as a boiler tube tube of a general boiler and a large boiler such as an industrial building, the thermal efficiency can be maximized, and energy can be saved by preventing various foreign substances such as rust or scale from remaining on the inner circumference of the pipe. Can be.
