Description

Technical Field

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

[0002] A metal plate power output device using a low-conductivity fluid as the electrolyte is entirely immersed in an open, unbounded fluid communication domain. This eliminates the need for dedicated electrolytes and offers highly stable output and a long lifespan. Due to the inherent low conductivity of the open fluid communication domain, multiple cells cannot be connected in series, resulting in low output voltage and power. When the load requires a higher voltage, an inverter-boost circuit module must be used to increase the voltage. However, the inherent characteristics of the inverter-boost module's electronic components can significantly reduce overall system efficiency, hindering the practical application of this type of energy output device. Most currently proposed technologies fail to address the issues of improving output voltage and operating efficiency (see 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 shortcomings of the existing metal plate counter-electrode power output device with low conductivity fluid as electrolyte that is difficult to use 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, thereby improving 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 efficiency, and reduces the overall manufacturing and operating costs, thereby promoting 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 voltage boosting of a low-conductivity fluid communication domain includes at least one of the following electric energy output modules, the electric energy output module including:

[0006] The insulator cabin has a metal plate counter electrode inside, and the lead of the metal plate counter electrode extends from the insulator cabin. The lower end side of the insulator cabin is provided with a lower opening, and the upper end surface of the insulator cabin is provided with an upper opening;

[0007] The inlet channel is connected to the lower opening, and the inlet channel is attached to the surface of the insulating chamber, spirally circling around once, and ends at an inlet, which is located at the bottom of the insulating chamber and faces downward. The outflow channel is connected to the upper opening, and the outflow channel is attached to the surface of the insulating chamber, spirally circling around once, and ends at an outlet, which is located at the top of the insulating chamber and faces upward. In one embodiment, the inlet channel and the outflow channel are attached to each other and arranged in parallel.

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

[0009] The low-conductivity fluid enters the insulator cabin from the external connected 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 solution, the fluid in the low-conductivity fluid connection domain enters the insulating cabin and, as an electrolyte, interacts with the metal plate counter-electrode to produce an electrochemical reaction. A potential difference is formed between the metal plate electrodes, and electrical energy is output to the outside through the leads. 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 surfaces generates interfacial reaction heat, which will cause the fluid temperature in the insulating cabin to rise. The high-temperature fluid has a relatively low density and floats upward, 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 pattern to finally reach the outlet, enter the fluid connection domain, and diffuse upward at the same time. The lower-temperature fluid in the connection domain near the inlet enters from the inlet, flows in a left-hand spiral pattern through the inlet channel, and finally reaches the lower opening of the insulating cabin and enters the interior of the insulating cabin to replenish the consumed fluid. The inlet and outlet channels are close together, and there is a temperature difference between the fluids inside them. Heat from the high-temperature fluid is transferred to the low-temperature fluid, completing heat exchange. Multiple modules are arranged in an array, and the metal plate electrodes are connected in series. 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 set of metal plate pairs, 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 increases. This 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 domain 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 a method and device for outputting electric energy 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 counterelectrode and the low-conductivity fluid when the internal temperature of the module is increased.

[0026] Figure 1The insulating cabin 1 of the embodiment of the present invention is a hexahedron as an example. There are metal plate counter-electrodes inside, including a positive electrode 2 and a negative electrode 3. The leads of the metal plate counter-electrodes extend from the insulating cabin 1. A lower opening 4 is provided on the side surface of the lower end of the insulating cabin 1, and an upper opening 5 is provided on the upper end surface of the insulating cabin. The insulating 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 are located inside the hexahedral insulating cabin, with a gap between 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; while the other is relatively 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 insulating cabin as a connection terminal. Figure 2 The figure shows the transparent treatment of the insulator cabin 1, the relative positions of the internal metal plate poles and the connection relationship of the lead wires.

[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 opening 4 of the insulating chamber 1 spirals around the surface of the insulating chamber 1 and ends at the inlet 7, which is downward. The arrows show the path of the fluid in the low-conductivity fluid domain entering the insulating chamber 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 outlet channel 8 connected to the upper opening 5 of the insulating chamber 1 spirals around the surface of the insulating chamber 1 and ends at the 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 insulating chamber 1.

[0028] Figure 5 The diagram shows the spatial structural relationship between the insulator cabin 1, the metal plate counter-electrode, and the inlet channel 6 and outlet channel 8. Note that the inlet channel 6 and outlet channel 8 are attached together, but the spiral directions are opposite. A low-conductivity fluid enters the insulator cabin 1 from the external connected domain along the inlet 7, inlet channel 6, and lower port 4. Driven by the thermal dynamics of internal resistance Joule heat and the interfacial reaction heat of the metal plate counter-electrode, the low-conductivity fluid inside the insulator cabin 1 flows along the upper port 5, outlet channel 8, and outlet 9 into the external connected domain, completing the circulation and renewal of the low-conductivity fluid inside the insulator cabin. The inlet channel 6 and outlet channel 8 are attached together, completing heat exchange during the circulation process, retaining most of the heat inside the insulator cabin 1. The entire multi-module system is immersed in the low-conductivity fluid.

[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. The lower opening and the upper opening can be staggered in the horizontal position. The inlet channel is connected to the lower opening, and the material of the inlet channel can be the same as that of the insulator cabin. The inlet channel adheres to the surface of the insulator cabin, rotates around the insulator cabin in a left-hand spiral pattern, and returns to the inlet position, with the final inlet at the bottom facing downward; while the outlet channel is connected to the upper opening, and the material of the outlet channel can also be the same as that of the insulator cabin. It adheres to the surface of the insulator cabin, rotates around the insulator cabin in a right-hand spiral pattern, and finally the outlet is at the top facing upward. The outer surfaces of one side of the inlet channel and the outlet channel adhere to each other and are arranged in parallel. Here, the rotation mode of the inlet channel and the outlet channel can be interchangeable, that is, the inlet channel adopts a right-hand spiral mode, and the outlet channel adopts a left-hand spiral mode, and other requirements remain unchanged.

[0030] The low-conductivity fluid domain can be a variety of artificially formulated chemical electrolytes, or it can be a closed fluid domain composed of natural liquids such as river or lake water, groundwater, seawater, rainwater, or tap water. Multiple modules are immersed in this fluid domain, and both the interior and exterior spaces of the modules are filled with the low-conductivity fluid. The low-conductivity fluid itself, as well as the dissolved oxygen, carbon dioxide, and other substances within it, undergo an electrochemical reaction with the aforementioned metal plate counter-electrodes, generating a potential difference between the two counter-electrodes. Typically, the more active metal plate is the positive electrode, and the other is the negative electrode. Simultaneously, the reaction between the low-conductivity fluid and the metal plate surfaces generates interfacial reaction heat. When energy is output to an external load, the internal resistance of the low-conductivity fluid also generates Joule heat, causing the low-conductivity fluid inside the insulator chamber to temperature rise. The liquid expands due to heat, reducing its density and becoming lighter. It then moves upward and is discharged through the upper port, outflow channel, and outlet into the external low-conductivity fluid connected domain. Simultaneously, the external low-conductivity fluid enters the insulator chamber through the inlet, inflow channel, and lower port for replenishment, forming a natural circulation that ensures the low-conductivity fluid inside the insulator chamber is continuously refreshed. Furthermore, the inlet and outlet channels are attached to each other. Heat from the higher-temperature, low-conductivity fluid in the outlet channel is transferred to the lower-temperature, low-conductivity fluid in the inlet channel, completing heat exchange. This ensures that the fluid temperature in the insulator compartment does not drop during the replenishment process. Multiple modules are connected in series via wires, with the positive and negative terminals connected in series, to generate a high-voltage output.

[0031] Figure 6 The diagram shows an array of multiple modules, with leads connected in series by wires, culminating in two wires leading to external output (not shown). These modules are arranged in an array within a low-conductivity fluid domain, connected in series by wires. These wires are covered with an insulating layer, sequentially connecting the active metal electrodes of adjacent modules with the inert metal electrodes of the next module. Finally, the first and last wires provide energy output to the load.
