Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a magnetic force self-driven heat exchange vehicle. Background Art

[0002] A heat exchanger is a device for heat exchange between two or more fluids at different temperatures to meet the needs of process conditions, and is widely used in the fields of petroleum, chemical industry, electric power, energy, and ships.

[0003] For a device that needs to be cooled, the heat taken out by the heat exchanger is usually directly discharged into the environment, such as the equipment cooler in a power plant and a power device, which will directly cause a waste of a part of heat and reduce the overall operating efficiency of the system. On the other hand, since flow heat exchange can significantly increase the heat transfer coefficient and reduce the size of the heat exchanger, in general heat exchanger designs, both fluids on both sides are in a flowing state. To maintain this flowing state, additional pump-type mechanical equipment needs to be equipped to provide a driving head to overcome the resistance of the heat exchanger itself and the connecting pipes to achieve continuous heat exchange.

[0004] In view of the above deficiencies, the utility model proposes a magnetic force self-driven heat exchange vehicle. The magnetic fluid heat exchange technology adopted has a higher heat transfer coefficient and lower fluid resistance compared with the traditional heat exchange technology, so as to achieve more efficient heat energy conversion; the whole of the utility model does not rely on external energy supply, and generates electric energy through the temperature difference heating sheet in the heat collection part to drive the electric rotor in the heat exchange part, so that the device achieves the effect of truly saving energy.

Specific embodiments

[0044] The following further describes the present invention with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0045] It should be noted that the orientation or positional relationship indicated by "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship when the product of this invention is normally placed, or the orientation or positional relationship commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0046] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0047] Refer to Figures 1 to 7 As shown, the present invention provides a magnetically self-driven heat exchange vehicle, including: a heat collection structure 1, a magnetic drive structure 2, a heat exchange structure 3, and a vehicle body structure 4;

[0048] Refer to Figure 2, one end of the vehicle body structure 4 is provided with a heat collection structure 1, a magnetic drive structure 2 is arranged inside the middle part of the vehicle body structure 4, and the other end of the vehicle body structure 4 is provided with a heat exchange structure 3; one end of the magnetic drive structure 2 is connected to the heat collection structure 1, the other end of the magnetic drive structure 2 is connected to the heat exchange structure 3, and universal rollers are arranged on the vehicle body structure 4.

[0049] Magnetic fluid is added to the heat collection structure 1. The heat collection structure 1 raises the temperature of the magnetic fluid in the magnetic fluid heat collection pipeline 12. The magnetic fluid with the increased temperature flows into the magnetic drive structure 2. The magnetic drive structure 2 increases the speed of the magnetic fluid. The accelerated magnetic fluid enters the heat exchange structure 3. The magnetic fluid is rotationally accelerated in the heat exchange structure 3 and heat exchange is completed. The magnetic fluid that has successfully completed heat exchange flows into the magnetic drive structure 2 again to increase the flow rate. Finally, the magnetic fluid that has completed acceleration enters the heat collection structure 1 again. At this time, the first cycle of acceleration is completed; then the cycle starts the second acceleration.

[0050] Refer to Figure 3 , the heat collection structure 1 includes a magnetic fluid heat collection pipeline 11, a thermoelectric heating sheet 14, a heat absorption plate 13, fin heat sinks 12 and a ventilation pipe 15;

[0051] The magnetic fluid heat collection pipeline 11 adopts a square cross-section pipe, and the pipeline is bent and placed flat on the heat absorption plate 13; a plurality of thermoelectric heating sheets 14 are equidistantly arranged in the middle of the heat absorption plate 13; a ventilation pipe 15 is arranged below the thermoelectric heating sheet 14, and a plurality of fin heat sinks 12 are equidistantly arranged on the upper inner wall of the ventilation pipe 15.

[0052] During operation, the magnetic fluid heat collection pipeline 11 adopts a square cross-section pipe to fully absorb heat, so that the magnetic fluid fully absorbs external heat; the thermoelectric heating sheet 14 utilizes the Seebeck effect to directly convert thermal energy into electrical energy. When generating electricity, there is no need for an indirect conversion process of first converting thermal energy into mechanical energy and then converting mechanical energy into electrical energy. The thermoelectric heating sheet 14 generates electrical energy to drive the electric rotor 321 of the heat exchange structure, and the magnetic force self-driven heat exchange vehicle achieves the effect of truly saving energy and achieving green environmental protection.

[0053] Refer to Figure 4 , the magnetic drive structure 2 includes a first magnetic drive component 21 and a second magnetic drive component 22;

[0054] The first magnetic drive component 21 and the second magnetic drive component 22 are symmetrically arranged on both sides inside the vehicle body structure 4;

[0055] The inlet end of the first magnetic drive component 21 is connected to the outlet end of the heat collection structure 1, the outlet end of the first magnetic drive component is connected to the inlet end of the heat exchange structure 3, the outlet end of the heat exchange structure is connected to the inlet end of the second magnetic drive component 22, and the outlet end of the second magnetic drive component 22 is connected to the inlet end of the heat collection structure 1.

[0056] Refer toFigure 5 , the first magnetic drive component 21 includes a cylindrical magnet 211, a magnetic sleeve 212, a magnetohydrodynamic pipeline 213, and a magnet sleeve 214;

[0057] The middle part of the magnetic sleeve 212 is cylindrical, and both ends are conical; the inside of the magnetic sleeve 212 is a cavity, the magnet sleeve 214 is arranged equidistantly along the inner cavity of the magnetic sleeve 212, the cylindrical magnet 211 is fixed inside the magnet sleeve 214, and the magnetohydrodynamic pipeline 213 horizontally penetrates through both ends of the magnetic sleeve 212.

[0058] To enable the magnetohydrodynamic to have a faster flow rate, the magnetic drive device is designed with a cylindrical magnetic drive field. To design a gradually changing gradient magnetic field, five cylindrical magnets 211 with gradually increasing magnetic field intensities are arranged in sequence from left to right, and the magnetic pole directions of adjacent magnets are placed in opposite directions, so that a magnetic field gradient gradually increasing along a certain direction can be obtained, thereby driving the magnetohydrodynamic.

[0059] Refer to Figure 6 , the heat exchange structure 3 includes an acceleration component 31 and a spiral heat exchange component 32; the acceleration component 31 is arranged inside the spiral heat exchange component 32; the spiral heat exchange component 32 is connected to the magnetic drive structure 2.

[0060] The heat exchange structure 3 is composed of a "Halbach" acceleration component 31 and a spiral heat exchange component 32. The acceleration component 31 is on the axis of the spiral heat exchange component 32. At the heat collection device 1, the electric energy generated by the temperature difference heating sheet 14 makes the electric rotor 321 rotate. The electric rotor 321 drives the acceleration component 31, that is, a plurality of magnets arranged according to the Halbach array rotate, making the magnetic field intensity of the array magnets greater, increasing the flow velocity of the magnetohydrodynamic on one side, and at the same time preventing the magnetohydrodynamic from becoming viscous after being adsorbed by the magnets and hindering the driving effect.

[0061] The spiral heat exchange component 32 includes an electric rotor 321, a heat exchange outer shell 322, a cold fluid outlet pipe 323, a cold fluid inlet pipe 324, a magnetohydrodynamic spiral pipe 325, and a metal plate 326; the heat exchange outer shell 322 is in a cylindrical shape. There is a hole opened upward on the upper outer surface on one side of the heat exchange outer shell 322, and the cold fluid outlet pipe 323 is installed on the hole. There is a hole opened downward on the lower outer surface on the other side of the heat exchange outer shell 322, and the cold fluid inlet pipe 324 is installed on the hole.

[0062] The metal plate 326 is sleeved and horizontally arranged at the central position inside the heat exchange outer shell 322, and the acceleration component 31 is installed on the metal plate 326; the electric rotor 321 is in a cylindrical shape, and one bottom surface of the electric rotor 321 is fixed on the metal plate 326;

[0063] The magnetohydrodynamic (MHD) spiral tube 325 is spirally wound around the metal plate 326 along the length direction of the metal plate 326. One end of the MHD spiral tube 325 is connected to the cold fluid outlet pipe 323, and the other end of the MHD spiral tube 325 is connected to the cold fluid inlet pipe 324 and is also connected to the outlet end of the MHD pipeline 23.

[0064] The MHD spiral tube 325 inside the spiral heat exchange component 32 enables heat to be rapidly transferred between the heat exchange media, so the heat exchange efficiency is high. Moreover, the internal structure of the spiral heat exchange component 32 is simple, easy to clean and maintain, and can ensure long-term stable operation.

[0065] Refer to Figure 7 , the acceleration component 31 includes a plurality of magnets, and the plurality of magnets are arranged in a Halbach array.

[0066] Adopting the magnetic field arrangement mode of the "Halbach" array can increase the magnetic field strength of the arranged magnetic field and make the magnetic field line arrangement more concentrated. The iron-nickel alloy can better block the magnetic field on the magnetic field weakening surface of the array magnet, making the magnetic field of the array magnet reach an almost one-sided enhanced magnetic field, while weakening the magnetic field strength on the other side. Blocking the magnetic field on the other side is to prevent the magnetohydrodynamic fluid from becoming viscous after being adsorbed by the magnet and thus hindering the driving effect. In this way, a stronger magnetic field can be achieved with fewer magnets.

[0067] In some preferred embodiments, there are two first heat exchange structures and second heat exchange structures with the same structure. The specific structures of the first heat exchange structure and the second heat exchange structure are the same as those of the heat exchange structure 3. The two heat exchange structures 3 are arranged side by side inside the vehicle body structure 4. The cold fluid inlet pipe 323 of the first heat exchange structure is connected to the outlet end of the first magnetic drive component. The cold fluid outlet pipe 324 of the first heat exchange structure is connected to the cold fluid outlet pipe 323' of the second heat exchange structure. The cold fluid inlet pipe 324' of the second heat exchange structure is connected to the inlet end of the second magnetic drive component.

[0068] The above embodiments only represent relatively preferred implementation manners, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
