Description

[0001] DUAL HEAT TRANSFER PIPE WITH HEAT TRANSFER FLUID

[0002] TECHNICAL FIELD

[0003] The invention is related to a dual heat transfer pipe with the heat transfer fluid that removes heat quickly with the phase-changing heat transfer fluid that can be used in heating and cooling.

[0004] The invention especially; it is related to the double heat transfer pipe which contains heat transfer fluid containing colemanite, borax, AI2O3, SiOs, CuO, TiCh, Si L, szaybelite, boron carbide, boron solid particles between 10-200 nanometers, which can change phase, do not cluster, located in the body wickless and in the wick line, which allows heat to be transferred from bottom to top, top to bottom and / or at every slope including horizontal, and allows the liquid formed after condensation to be carried back up through the wick while the heat transfer is downward.

[0005] THE KNOWN STATE OF THE TECHNIQUE

[0006] A heat pipe is a heat transfer device with extremely high thermal conductivity. When the hot side of a heat pipe touches the thermally conductive surface, the chemical liquid inside evaporates with the heat received from the surface and carries the heat to the cold end. In short, heat pipes can be defined as passive heat pumps, which displace heat as a result of the laws of physics. Heat pipes around the world are produced in the form of a single pipe. These pipes work with a heat transfer fluid that contains two phases: liquid and gas.

[0007] The heat pipes produced in the current technique work only in a vertical position and in a way that can transmit heat from the bottom up. They cannot transfer heat horizontally or from top to bottom.

[0008] In the current technique, to prepare the pipes, vacuuming is required before adding the phaseseparating heat transfer fluids into the pipe.

[0009] As a result, in order to solve the above-mentioned problems that exist in the current technique, the need for a new economical, convenient, heat transfer heat pipes and the lack of existing solutions made it necessary to make a development in the relevant technical field. THE PURPOSE OF THE INVENTION

[0010] The current invention relates to the dual heat pipe, which can work at different angles, from bottom to top, from top to bottom, horizontally or at different slopes, developed to eliminate the above- mentioned disadvantages and bring new advantages to the relevant technical field.

[0011] The most important purpose of the invention is to include a heat transfer system with heat transfer fluids that can change phase. The phase is divided from the distributed liquid phase to the vapor phase and conducts heat. After transmitting the heat, it condenses and returns. In the phase-change heat transfer system, evaporation is accelerated with the heat received, thanks to the solid particles between 10 and 200 nanometers such as colemanite, borax, AI2O3, SiOs, CuO, TiCh, SiL, szaybelite, boron carbide and boron. Since these nano particles have a dispersed effect, heat transfer is achieved quickly. After heat transfer, these solid particles do not clump and do not stick to each other during condensation. It has a high capacity to retain heat. Thanks to these nanoparticles, heat pipes can be prepared without vacuuming. There is no need for sintering or opening grooves or pockets on the inner surfaces of heat pipes. Thus, it can work vertically upwards or downwards and horizontally without shape restrictions.

[0012] Another purpose of the invention is that the heat transfer fluid contained in it does not have any flammable, explosive, allergenic, carcinogenic, pathogenic effects, so that it does not adversely affect the environment and human health.

[0013] Another purpose of the invention is that, as a result of our R&D studies, the phase-changing fluid has a heat conduction coefficient of 16098 W / mK. Therefore, the invention reacts very quickly and provides rapid heat transfer.

[0014] Another purpose of the invention is to eliminate the need for vacuuming inside the heat pipe during the manufacturing of the heat pipe.

[0015] The characteristics and features of the invention and all the information will be understood more clearly thanks to the detailed explanation written to make references to what is given and presented, and therefore the evaluation should be added to these words and detailed explanation.

[0023] DETAILED DESCRIPTION OF THE INVENTION

[0024] In this detailed description, the preferred configurations of the dual heat transfer pipe with heat transfer fluid are explained only for a better understanding of the subject and in such a way that they do not create any limiting effects.

[0025] In figure 1-2 shows the dual heat pipe with heat transfer fluid subject to the invention and its details. The invention; it consists of body (10), wickless line (11), wick line (12) and wick (13).

[0026] The heat pipe has two different channels: the wickless line (11), and the wick line (12). The first of these channels, the wickless line (11), ensures that the heat to be transferred is transferred at every slope between bottom to top and horizontal. The second channel, the wick line (12), provides heat transfer at every slope, from top to bottom and horizontally.

[0027] In the invention, there are solid particles between 10-200 nanometers such as colemanite, borax, AI2O3, SiO3, CuO, TiO2, boron carbide, szaybelite and boron in the heat transfer fluid that can change phase, and thanks to these particles, evaporation is accelerated with the heat received. Since these nanoparticles have a catalyst effect, heat transfer is achieved quickly. After heat transfer from bottom to top, these solid particles do not clump (non-clustering) and do not stick to each other during the condensation that occurs in the upper part of the wickless line (11). In addition, thanks to these nanoparticles, heat pipes can be prepared without vacuuming. Sintering, grooving or pocketing process is not required on the inner surfaces of these lines (11,12). Thus, it can work vertically and horizontally without shape restrictions. Thus, it can work vertically and horizontally without shape restrictions. During the downward heat transfer, the heated fluid ensures downward heating of the wick line (12), and ensures that condensation occurs at the bottom. The liquid formed after condensation is carried back up through the wick (13).

[0028] Alternatively, in the invention, the phase-changing heat transfer fluid may contain the above- mentioned solid particles between 10-50 or 50-100 or 100-150 nanometers.

[0029] The scope of protection of this application has been determined in the claims section and cannot be limited to what is described above for exemplary purposes, it is clear that a person skilled in the art can demonstrate the innovation in the invention by using similar embodiments and / or can apply this embodiment to other areas with similar purposes used in the relevant technique. Therefore, it is obvious that such structuring will lack the criteria of innovation and especially overcoming the known state of the technique.
