Description

Technical Field

[0001] The present invention relates to the technical field of new concept special-purpose power supply, and in particular to an electric energy output device and method for series voltage boosting in low-conductivity fluid connection domains. Background Art

[0002] The metal plate power output device using low-conductivity fluid as electrolyte is immersed in an open and boundless fluid connection domain as a whole. It does not need to carry a dedicated electrolyte and has the characteristics of high stability output and long life. Due to the low conductivity of the open fluid connection domain itself, multiple monomers are difficult to operate in series, and the output voltage and power of the monomers are very low. When the voltage required by the load is higher, an inverter boost circuit module has to be used to increase the voltage. The characteristic problems of the electronic components of the inverter boost module itself will cause a serious decrease in the overall efficiency of the system, hindering the actual engineering application of this type of energy output device. Most of the related technologies currently proposed do not consider how to improve the output voltage and operating efficiency (reference patents: CN201810253210.X, CN202121278149.8, CN202010672253.9, etc.). Summary of the invention

[0003] The technical problem to be solved by the present invention is: to overcome the disadvantage that the existing metal plate counter-electrode power output device with low conductivity fluid as electrolyte is difficult to be used in series in the fluid connection domain, and to provide a power output device and method for series boosting in the low conductivity fluid connection domain, so as to achieve high voltage and high power output, and its own structure increases the temperature of the low conductivity fluid inside the module, enhances the chemical reaction activity at the interface between the electrolyte and the metal plate counter-electrode, so as to improve the overall operating efficiency and output power of the system, and at the same time abandons the boost module that reduces the operating efficiency of the system, directly outputs high voltage and high power to the load, reduces the complexity and failure rate of the system, improves the efficiency, and reduces the overall manufacturing and operating costs, so as to promote the effective application of the metal plate power output device using low conductivity fluid as electrolyte in actual engineering in the connection domain.

[0004] The technical solution adopted by the present invention to solve the above problems is:

[0005] An electric energy output device for series boosting of low-conductivity fluid communication domains includes at least one of the following electric energy output modules, wherein the electric energy output module includes:

[0006] An insulator cabin has a metal plate counter electrode inside, a lead wire of the metal plate counter electrode extends out of the insulator cabin, a lower opening is provided on the side surface of the lower end of the insulator cabin, and an upper opening is provided on the upper end surface of the insulator cabin;

[0007] The inlet channel is connected to the lower port, and the inlet channel is attached to the surface of the insulator cabin and spirally circles around once, and ends with an inlet, and the inlet is downward at the bottom of the insulator cabin; the outlet channel is connected to the upper port, and the outlet channel is attached to the surface of the insulator cabin and spirally circles around once, and ends with an outlet, and the outlet is upward at the top of the insulator cabin. In one embodiment, the inlet channel and the outlet channel are attached to each other and arranged in parallel.

[0008] A method for outputting electric energy applied to boosting the voltage of low-conductivity fluid-connected domains in series, which is performed by the above-mentioned electric energy output device applied to boosting the voltage of low-conductivity fluid-connected domains in series, comprises:

[0009] The low-conductivity fluid enters the insulator compartment from the external communication domain along the inlet, the inlet channel, and the lower port;

[0010] Driven by the thermal power of the internal resistance Joule heat and the interface reaction heat of the positive and negative electrodes of the metal plate electrodes, the low-conductivity fluid inside the insulator cabin flows along the upper port, the outflow channel, and the outlet into the external connected domain.

[0011] In the above technical scheme, the fluid in the low-conductivity fluid connection domain enters the insulating cabin, and as an electrolyte, it interacts with the metal plate counter electrode to produce an electrochemical reaction, forming a potential difference between the metal plate electrodes, and outputting electrical energy to the outside through the lead. At the same time, the internal resistance of the liquid between the metal plate counter electrodes generates Joule heat, and the energy conversion between the low-conductivity fluid and the metal plate counter electrode surface generates interfacial reaction heat, which will cause the fluid temperature in the insulating cabin to rise. The fluid with high temperature has relatively low density and floats up, forming a temperature and density gradient in the insulating cabin, generating a convection driving force. The high-temperature fluid enters the outlet channel from the upper opening of the insulating cabin and flows in a right-hand spiral mode and finally reaches the outlet, enters the fluid connection domain, and diffuses upward at the same time. The fluid with lower temperature in the connection domain near the entrance enters from the entrance, flows in a left-hand spiral mode through the inlet channel and finally reaches the lower opening of the insulating cabin, enters the interior of the insulating cabin, and replenishes the consumed fluid. The inlet channel and the outflow channel are attached to each other, and there is a temperature difference between the fluids inside the two. The heat of the high-temperature fluid is transferred to the low-temperature fluid to complete the heat exchange. Multiple modules are arranged in an array, and the metal plate electrodes are connected in series in sequence. The equivalent resistance of low conductivity in the inlet and outlet channels is much larger than the resistance of the series wires. After multiple modules are connected in series, the total output voltage increases, and the voltage value is close to the output voltage of a single module as a multiple of the number of modules.

[0012] The beneficial effects of the present invention compared with the prior art are:

[0013] (1) The insulating cabin structure ensures the modularization of a group of metal plates, providing a structural basis for multi-module series voltage boosting;

[0014] (2) The inlet and outlet channels increase the length of the low-conductivity fluid. Although multiple modules are in the same connected domain, the interconnected resistance increases, which ensures the voltage boost of multiple modules in series from the circuit perspective.

[0015] (3) The spiral structures in the inlet and outlet channels are attached together. During the passage of the low-conductivity fluid, heat is exchanged, and the temperature of the low-conductivity fluid inside the insulation cabin rises, which thermally ensures that the electrochemical reaction can continue to proceed efficiently in a low-temperature environment.

[0016] (4) The temperature rise inside the insulator cabin forms a convection drive, which automatically completes the renewal and replacement of the low-conductivity fluid in the area connected to the outside world, ensuring the continuous and stable energy output.

[0024] The present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0025] The present invention proposes an electric energy output method and device for series voltage boosting in a low-conductivity fluid connection domain, which can realize the series output of multiple modules in the low-conductivity fluid domain and enhance the electrochemical reaction activity between the metal plate counter electrode and the low-conductivity fluid when the internal temperature of the module is increased.

[0026] Figure 1The insulator cabin 1 of the embodiment of the present invention is taken as an example of a hexahedron, and there are metal plate counter-electrodes inside, including a positive electrode 2 and a negative electrode 3, and the lead of the metal plate counter-electrode extends from the insulator cabin 1. A lower opening 4 is provided on the side of the lower end of the insulator cabin 1, and an upper opening 5 is provided on the upper end surface of the insulator cabin. The insulator cabin is made of insulating materials such as engineering plastics, ceramics, glass, epoxy fiberglass, etc., and can be a variety of hollow container shapes. Taking a parallelepiped as an example, two vertically placed metal plate counter-electrodes facing each other in parallel are located inside the hexahedral insulating cabin, and there is a gap in the middle of the metal plate counter-electrodes. One of the metal plate counter-electrodes has a higher chemical activity, that is, it is more active, such as metals such as lithium, magnesium, aluminum, zinc, or their alloys; and the other is more inert, such as stainless steel, copper, silver, platinum, gold, or other metals or their alloys. The upper end of each metal plate counter-electrode has a lead extending out of the insulator cabin as a wiring terminal. Figure 2 The figure shows the transparent treatment of the insulator cabin 1, the relative positions of the internal metal plate pairs and the connection relationship of the leads.

[0027] Figure 3 The figure shows the connection diagram between the insulator cabin and the inlet channel, hiding the metal plate counter-pole. Figure 3 In the figure, the inlet channel 6 connected to the lower port 4 of the insulator cabin 1 is attached to the surface of the insulator cabin 1 and spirally circles around once, and ends with an inlet 7, which is downward. The direction of the arrow shows the path of the fluid in the low conductivity fluid domain entering the insulator cabin 1. Figure 4 The figure shows the connection diagram between the insulator cabin and the outflow channel, hiding the metal plate counter-pole. Figure 4 In the figure, the outflow channel 8 connected to the upper opening 5 of the insulator cabin 1 is attached to the surface of the insulator cabin 1 and spirally circles around once, and ends with an outlet 9, which is upward. The direction of the arrow shows the path of the fluid in the low conductivity fluid domain flowing out of the insulator cabin 1.

[0028] Figure 5 The spatial structural relationship between the insulator cabin 1, the metal plate counter-electrode, and the inlet channel 6 and the outlet channel 8 is shown. Note that the inlet channel 6 and the outlet channel 8 are attached together, but the spiral direction is opposite. Among them, the low-conductivity fluid enters the insulator cabin 1 from the external connection domain along the inlet 7, the inlet channel 6, and the lower port 4. Driven by the thermal power of the internal resistance Joule heat and the interface reaction heat of the metal plate counter-electrode, the low-conductivity fluid inside the insulator cabin 1 enters the external connection domain along the upper port 5, the outlet channel 8, and the outlet 9, completing the circulation and renewal of the low-conductivity fluid inside the insulator cabin. The inlet channel 6 and the outlet channel 8 are attached to each other, and the heat exchange is completed in the circulation process, leaving most of the heat inside the insulator cabin 1. The multi-module system is immersed in the low-conductivity fluid as a whole.

[0029] In short, a lower opening is formed on a side surface of the lower end of the insulator cabin, and an upper opening is formed on one end of the upper end surface of the insulator cabin, and the lower opening and the upper opening can be staggered in the lateral position. The inlet channel is connected to the lower opening, and the material of the inlet channel can be consistent with the material of the insulator cabin. The inlet channel is attached to the surface of the insulator cabin, rotates around the insulator cabin in a left-hand spiral mode, and returns to the entrance position, and finally the entrance is at the bottom downward; while the outflow channel is connected to the upper opening, and the material of the outflow channel can also be consistent with the material of the insulator cabin, attached to the surface of the insulator cabin, rotates around the insulator cabin in a right-hand spiral mode, and finally the outlet is at the top upward. The outer surfaces of one side of the inflow channel and the outflow channel are attached to each other and arranged in parallel. Here, the rotation mode of the inflow channel and the outflow channel can be interchangeable, that is, the inflow channel is in a right-hand spiral mode, and the outflow channel is in a left-hand spiral mode, and other requirements remain unchanged.

[0030] The low-conductivity fluid domain can be various artificially prepared chemical electrolytes, or it can be a fluid closed domain composed of natural river and lake water, groundwater, seawater, rainwater or tap water. Multiple modules are immersed in this fluid domain, and the internal and external spaces of the modules are filled with low-conductivity fluid. The low-conductivity fluid itself and the oxygen, carbon dioxide, etc. dissolved inside react electrochemically with the aforementioned metal plate counter-electrodes, generating a potential difference between the two counter-electrodes. Generally, the more active metal plate is the positive electrode and the other is the negative electrode. At the same time, the reaction process between the low-conductivity fluid and the surface of the metal plate generates interfacial reaction heat, and the internal resistance of the low-conductivity fluid itself also generates Joule heat when outputting energy to the external load, so that the temperature of the low-conductivity fluid inside the insulator cabin rises, the liquid expands due to heat, the density decreases, and it moves upward, and is discharged into the external low-conductivity fluid connection domain through the upper port, the outflow channel and the outlet. At the same time, the external low-conductivity fluid enters the insulator cabin through the inlet, the inflow channel and the lower port to replenish, forming a natural cycle to ensure that the low-conductivity fluid inside the insulator cabin is continuously renewed. In addition, the inlet channel and the outlet channel are attached to each other, and the heat of the low-conductivity fluid with a higher temperature in the outlet channel is transferred to the low-conductivity fluid with a lower temperature in the inlet channel to complete the heat exchange, so as to ensure that the fluid temperature in the insulator cabin will not decrease due to the replenishment process. Multiple of the above modules are connected in series with positive and negative electrodes through wires to form external high-voltage output.

[0031] Figure 6 The array state of multiple modules is shown, and the leads are connected in series with wires, and finally two wires are led out for external output (not shown). Multiple modules are arranged in an array in a low-conductivity fluid domain and connected in series by wires. Here, the wires are covered with an insulating layer, and the active metal poles of adjacent modules are connected in series with the inert metal poles of the next module in turn, and finally the first and last two wires provide energy output to the load.
