Description

Technical Field

[0001] This utility model relates to the field of battery temperature control technology, specifically a biomimetic microbial fuel cell temperature control structure. Background Technology

[0002] A biomimetic microbial fuel cell is a device that uses microorganisms to directly convert the chemical energy in organic matter into electrical energy. When using a biomimetic microbial fuel cell, it is usually necessary to configure a corresponding temperature control structure to keep the microorganisms in a suitable temperature environment to ensure their activity and reaction efficiency. Existing biomimetic microbial fuel cell temperature control structures sometimes use direct heating and cooling of the battery to control its temperature. However, during the heating or cooling process, temperature fluctuations may cause the battery to exceed the suitable temperature range for some time, which may affect the reaction efficiency of the biomimetic microbial fuel cell. Utility Model Content

[0003] The purpose of this invention is to provide a biomimetic microbial fuel cell temperature control structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A biomimetic microbial fuel cell temperature control structure includes a water tank, an inlet pipe, an outlet pipe, and a partition. The ends of the inlet pipe and the outlet pipe are connected to the inside of the water tank. The partition is located inside the water tank and contains several battery columns. Each battery column contains a phase change heat storage layer, and an integrated wire is fixedly connected between adjacent battery columns.

[0006] Furthermore, a connecting cover is provided at the top of the battery column.

[0007] Furthermore, a swivel ring is fixedly connected to the end of the water inlet pipe away from the water tank, and a connecting seat is fixedly connected to the end of the water outlet pipe away from the water tank, with a swivel seat provided on the side of the connecting seat.

[0008] Furthermore, the end face of the swivel ring away from the water inlet pipe is fixedly connected to a plug ring, and the end face of the connector away from the water outlet pipe is provided with a plug groove.

[0009] Preferably, both sides of the top surface of the partition are fixedly connected to limiting seats that are slidably connected to the inner side of the water tank. A connecting ring is fixedly connected to the top surface of the limiting seat. Positioning seats are fixedly connected to the two inner sides of the water tank corresponding to the limiting seats. A positioning screw is screwed to the inner side of the positioning seat and screwed to the inner side of the adjacent connecting ring. The partition is equipped with two positioning screws. Two L-shaped plates are fixedly connected to the top surface of the partition.

[0010] Furthermore, a connecting pipe is fixedly connected to the inner side of the two limiting seats.

[0011] Furthermore, the bottom surface of the partition plate is provided with an arc-shaped groove corresponding to the connecting pipe, and two connecting pipes communicating with the inside of the connecting pipe are fixedly connected to the inner side of the partition plate. The side of the connecting pipe is fixedly connected to the inner side of the adjacent limiting seat, and the bottom end of the connecting pipe is communicating with the inside of the arc-shaped groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The battery column is equipped with a phase change heat storage layer. Water is supplied to the water tank through the inlet pipe. After passing through the bottom of the battery column, the water flows out through the outlet pipe. The water maintains the temperature of the battery column, and the integrated wires are separated from the water by a partition, which helps to improve the safety of the battery. The phase change heat storage layer inside the battery column has the characteristic of small temperature change. When the temperature inside the battery column is low, the phase change heat storage layer can quickly replenish the heat for the microorganisms inside the battery column. When heat is generated inside the battery column, the phase change heat storage layer can quickly absorb the heat from the battery column. Then, the water carries away the excess heat from the phase change heat storage layer. This helps to reduce the temperature fluctuation inside the battery column and keep the internal temperature of the battery within a suitable range, minimizing the impact of water temperature changes on the fuel cell.

[0014] 2. Two limiting seats are fixedly connected to a connecting pipe, allowing two water tanks to be connected in series as needed. This connects the inlet pipe to the adjacent outlet pipe, enabling water to flow sequentially between the two tanks and thus control the temperature of the battery cells within each tank. When maintenance is required on the battery in one tank, the partition can be moved downwards to connect the inlet pipe to the corresponding connecting pipe, allowing water to flow through the connecting pipe to the next tank. While the battery in one tank is being inspected or replaced, temperature control of the battery cells in the other tank can continue, minimizing the impact of maintenance on the remaining fuel cells.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 In this embodiment of the invention, a biomimetic microbial fuel cell temperature control structure includes a water tank 1, an inlet pipe 4, an outlet pipe 5, and a partition 6. The ends of both the inlet pipe 4 and the outlet pipe 5 are connected to the interior of the water tank 1. The partition 6 is disposed inside the water tank 1, and a plurality of battery columns 2 are disposed inside the partition 6. The partition 6 is slidably disposed inside the water tank 1, and the battery columns 2 are slidably disposed on the inner side of the partition 6. Rubber pads are disposed between the water tank 1 and the partition 6, and between the battery columns 2 and the partition 6. A phase change heat storage layer 21 is disposed inside the battery column 2, and the exterior of the battery column 2 is designed as a double layer. The structure consists of a middle hollow layer filled with phase change thermal storage material to form a phase change thermal storage layer 21. The integrated wire 3 is designed with a mitochondrial biomimetic wave-shaped circular nanocatalytic electrode and electrode membrane. The top of the battery column 2 is provided with a connecting cover 22, and an integrated wire 3 is fixedly connected between two adjacent battery columns 2. The integrated wire 3 is located on the top of the partition 6, while the water inlet pipe 4 and the water outlet pipe 5 are located at the bottom of the partition 6. Several battery columns 2 are connected end to end by several integrated wires 3, and one end of one integrated wire 3 is connected to the battery column 2, while the other end extends to the outside of the water tank 1.

[0024] Specifically, constant-temperature water can be supplied to the water tank 1 through the inlet pipe 4. After passing the bottom of the battery column 2, the water in the water tank 1 can flow out through the outlet pipe 5. The water can carry away excess heat from the phase change heat storage layer 21 or heat the phase change heat storage layer 21. The phase change material of the phase change heat storage layer 21 has the characteristic of small temperature change. When the temperature inside the battery column 2 is low, the phase change heat storage layer 21 will release heat, which can replenish the heat of the microorganisms inside the battery column 2 in a relatively timely manner. The water can heat the phase change heat storage layer 21, thus generating more heat inside the battery column 2. At the same time, the phase change heat storage layer 21 can absorb the heat inside the battery column 2 in a relatively timely manner, and then the excess heat on the phase change heat storage layer 21 is carried away by water. The water indirectly heats or cools the inside of the battery column 2 through the phase change heat storage layer 21, thereby maintaining the temperature of the battery column 2 through the constant temperature water and the phase change heat storage layer 21, and controlling the temperature inside the battery column 2. This helps to reduce the temperature fluctuation inside the battery column 2 and keep the internal temperature of the battery within a suitable range. In addition, the separator 6 separates the integrated wire 3 from the water, which helps to improve the safety of the battery.

[0025] Several support frames can be installed on the bottom surface of the water tank 1 to provide auxiliary support for the bottom of the battery column 2.

[0026] Example 1

[0027] like Figure 5-6 As shown, in this embodiment, both sides of the top surface of the partition 6 are fixedly connected to limiting seats 62 that are slidably connected to the inner side of the water tank 1. A connecting ring 64 is fixedly connected to the top surface of the limiting seat 62. Positioning seats 11 are fixedly connected to the two inner sides of the water tank 1 corresponding to the limiting seats 62. A positioning screw 7 is screwed to the inner side of the positioning seat 11 and screwed to the inner side of the adjacent connecting ring 64. The water tank 1 can limit the height of the limiting seat 62 by the positioning screw 7, thereby limiting the position of the partition 6 and connecting the partition 6 to the water tank 1. The partition 6 is equipped with two positioning screws 8. Two L-shaped plates 66 are fixedly connected to the top surface of the partition 6. A connecting pipe 63 is fixedly connected to the inner side of the two limiting seats 62.

[0028] In practical implementation, two water tanks 1 can be connected in series as needed. A set of water circulation equipment can be used to control the temperature of the battery posts 2 in the two water tanks 1. Water can flow sequentially in the two water tanks 1, thereby controlling the temperature of the battery posts 2 in the water tanks 1. When it is necessary to repair the battery in one of the water tanks 1, the positioning screw 7 can be rotated to disengage the bottom of the positioning screw 7 from the connecting ring 64 and unscrew the positioning screw 7 from the positioning seat 11. At this time, the partition 6 can be moved downward through the L-shaped plate 66 so that the bottom surface of the partition 6 is in contact with the bottom surface of the water tank 1. At this time, the inlet pipe 4 and the outlet pipe 6 can be connected. Water pipes 5 correspond to connecting pipes 63. Water in inlet pipe 4 can flow directly through connecting pipe 63 to outlet pipe 5, thus passing directly through the interior of water tank 1. Then, battery column 2 can be removed from partition 6. When repairing or replacing the battery in one water tank 1, the temperature of battery column 2 in another water tank 1 can be controlled, which helps to reduce the impact of repair on other fuel cells. Then, positioning screw 2 can be screwed into the corresponding positioning seat 11, and then the bottom of positioning screw 2 8 is screwed into the adjacent connecting ring 64, thereby limiting the position of partition 6 through positioning screw 2 8.

[0029] like Figure 4 As shown, in this embodiment, a swivel ring 41 is fixedly connected to the end of the water inlet pipe 4 away from the water tank 1, and a connecting seat 51 is fixedly connected to the end of the water outlet pipe 5 away from the water tank 1. A swivel seat 52 is provided on the side of the connecting seat 51, and the swivel seat 52 can move on the water outlet pipe 5. A plug ring 42 is fixedly connected to the end face of the swivel ring 41 away from the water inlet pipe 4, and a plug groove 53 is provided on the end face of the connecting seat 51 away from the water outlet pipe 5.

[0030] In specific implementation, when connecting two water tanks 1 in series as needed, the insertion ring 42 on the engagement ring 41 can be inserted into the adjacent insertion slot 53, so that the engagement ring 41 abuts against the adjacent connecting seat 51. Then, the engagement seat 52 can be screwed onto the engagement ring 41, so that the inner side of the engagement seat 52 screws into the side of the engagement ring 41. The engagement ring 41 is connected to the connecting seat 51 through the engagement seat 52, thereby connecting the inlet pipe 4 to the adjacent outlet pipe 5, and then connecting the two adjacent water tanks 1 in series. Then, the unconnected inlet pipe 4 and outlet pipe 5 are both connected to the water circulation equipment. The water circulation equipment transports water to one water tank 1 through the inlet pipe 4 of one water tank 1, and then transports water to the other water tank 1 through the interconnected inlet pipe 4 and outlet pipe 5. Water can be transported back to the water circulation equipment through the outlet pipe 5 of the other water tank 1.

[0031] Example 2

[0032] Based on Example 1, such as Figure 6As shown, in this embodiment, the bottom surface of the partition 6 is provided with an arc-shaped groove 61 corresponding to the connecting pipe 63. Two connecting pipes 65 that communicate with the inside of the connecting pipe 63 are fixedly connected to the inner side of the partition 6. The side of the connecting pipe 65 is fixedly connected to the inner side of the adjacent limiting seat 62, and the bottom end of the connecting pipe 65 communicates with the inside of the arc-shaped groove 61. The inside of the connecting pipe 63 can communicate with the arc-shaped groove 61 through the connecting pipe 65.

[0033] In practice, when the battery column 2 needs to be repaired or replaced, the water at the bottom of the separator 6 can enter the outlet pipe 5 when the separator 6 is moved downward. After the separator 6 is moved to the bottom of the inlet pipe 4 and the outlet pipe 5, the water at the bottom of the separator 6 can be collected in the arc-shaped groove 61 and then flow into the connecting pipe 63 through the connecting pipe 65, thereby avoiding the accumulation of too much water at the bottom of the separator 6.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
