Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery heat dissipation, and in particular to an integrated liquid-cooled radiator for a new energy vehicle battery. Background Art

[0002] New energy batteries refer to secondary batteries used in new energy vehicles, energy storage systems, power tools and other fields. They have the characteristics of high energy density, long cycle life and low environmental pollution. The heat dissipation of new energy batteries is the key to ensuring battery performance, safety and lifespan.

[0003] At present, liquid cooling is a heat dissipation method with relatively high heat dissipation efficiency. Its working principle is to use liquid (such as coolant) as a heat dissipation medium, absorb the heat generated by the battery through the circulating coolant, and transfer the heat to the external radiator for dissipation. Its advantage is high heat dissipation efficiency and the ability to accurately control the temperature of the battery pack, so that the battery pack is in a uniform temperature environment.

[0004] However, in actual use, it was found that when the battery is running for a long time or encountering a high temperature environment in summer, the battery pack is very likely to generate high temperatures. At this time, although the coolant in the liquid cooling system can play a certain heat dissipation role, its effect can only cover the initial flow area. As the coolant flows in the pipe, the temperature of the coolant itself will increase significantly, and it is difficult to dissipate heat as efficiently as in the initial stage, resulting in poor heat dissipation of the cooling pipe in the second half. Moreover, when the battery is operating at high power, the difference in heat dissipation effect between the front and rear ends of the cooling pipe will become more and more obvious.

[0005] In response to the above problems, there is an urgent need for innovative designs based on the original liquid cooling. Summary of the Invention

[0006] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. Specifically, the purpose of the present invention is to provide an integrated liquid cooling radiator for new energy vehicle batteries to solve the problem proposed in the above background technology that traditional liquid cooling cannot cool the flowing coolant, resulting in the coolant temperature in the second half being too high and unable to achieve a good heat dissipation effect.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: an integrated liquid-cooled radiator for a new energy vehicle battery, comprising a liquid cooling plate and a liquid cooling pipe laid inside the liquid cooling plate, wherein both ends of the liquid cooling pipe are respectively connected to a refrigeration mechanism and a temporary cooling pipe;

[0008] The liquid cooling pipe is divided into a core pipe and an edge pipe. The middle position of the core pipe and the edge pipe is connected to the temporary cooling pipe. The cooling liquid in the core pipe is transported to the temporary cooling pipe for cooling and then transported to the edge pipe.

[0009] An inlet pipe and a discharge pipe are respectively provided at both ends of the temporary cooling pipe. A solenoid valve is installed on the discharge pipe. A temperature controller for controlling the start and stop of the solenoid valve is installed on the outside of the temporary cooling pipe. After the solenoid valve is opened, the coolant inside the inlet pipe gradually flows into the temporary cooling pipe, forcing the high-temperature coolant in the temporary cooling pipe into the discharge pipe.

[0010] Preferably, at least two threaded pipes are connected to the side curved surface in the middle of the core pipeline, and a bellows is installed at the other end of each threaded pipe. The bellows is in a compressed state under low temperature conditions, and the end of each bellows is provided with a hose connected to the edge pipeline.

[0011] Preferably, a sealing plug is provided inside the drainage pipeline, and a spring is connected to the other side of the sealing plug. After the coolant inside the temporary cooling pipe enters the drainage pipeline, it pushes the sealing plug to slide horizontally along the sealing cavity in the drainage pipeline, accompanied by the compression of the spring.

[0012] Preferably, a rack is connected to the middle of the sealing plug close to the spring, a gear is engaged above the rack, and a shift rod is installed on the outside of the gear, which drives the rack to slide through the sealing plug to rotate the gear and further drive the shift rod to rotate.

[0013] Preferably, a layer of annular gasket is provided on the outside of the shifting rod, and the annular gasket is embedded in the inner wall of the temporary cooling pipe.

[0014] Preferably, a shift block is installed on the surface of the bellows, and the shift block is connected to the shift rod. The rotation of the shift rod drives the shift block to draw a circle, further driving the bellows to stretch.

[0015] Preferably, a temperature sensor is plugged into the top of the temperature controller, and a probe of the temperature sensor extends into the inlet position of the drainage pipeline.

[0016] Preferably, the drain pipeline is connected to a recovery pipeline at a position away from the solenoid valve, and the high-temperature coolant in the temporary cooling pipeline enters the recovery pipeline for recovery at the end of the sliding stroke of the sealing plug.

[0017] Preferably, the refrigeration mechanism includes a heat exchanger, the outlet of the heat exchanger is connected to a liquid storage tank, the inlet of the heat exchanger is connected to a recovery pipeline, the side wall of the liquid storage tank is connected to a circulation pump, the outlet of the circulation pump is connected to a four-way pipe, and the four-way pipe is respectively connected to the core pipeline and the liquid inlet pipeline.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Through the coordinated work of liquid cooling pipes and temporary cooling pipes, the liquid cooling pipes are distributed into core pipes and edge pipes. When the battery continues to operate at high power and causes the battery to gradually heat up, the high-temperature coolant that absorbs the heat of the core pipes in the first half will be cooled through the temporary cooling pipes, and then transported to the edge pipes for auxiliary heat dissipation in the second half, thereby improving the overall heat dissipation effect. Finally, it is recycled to the refrigeration mechanism for reuse, realizing an integrated circulating heat dissipation function.

[0020] At the same time, an automatic replacement function of coolant is added to the temporary heat dissipation pipe. Under high temperature conditions, the temperature controller controls the solenoid valve to open, and the coolant in the temporary heat dissipation pipe will be directly replaced into the heat exchanger for recovery. In low temperature conditions, the solenoid valve is closed and the coolant is stored in the temporary heat dissipation pipe. By flexibly switching between high-temperature dynamic replacement and low-temperature static storage, the cooling effect of the temporary cooling pipe is ensured, ineffective heat dissipation is avoided, and the utilization rate of the coolant is maximized.

[0021] In addition, an expandable bellows is added to the end of the threaded tube in the core area of ​​the heat exchange. The gear drives the lever to rotate, and the bellows automatically expands in a high-temperature environment, increasing its overall length, thereby extending the flow path of the coolant. Under low-temperature conditions, the bellows will automatically retract to achieve rapid circulation flow, so that the residence time of the high-temperature coolant in the core pipeline after entering the temporary cooling pipeline can be adjusted in real time according to temperature changes, thereby improving the cooling efficiency while taking into account the stability of the overall coolant flow.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 The present invention provides a technical solution: an integrated liquid cooling radiator for a new energy vehicle battery, comprising a liquid cooling plate 1, and a liquid cooling pipe 2 laid inside the liquid cooling plate 1, wherein both ends of the liquid cooling pipe 2 are respectively connected to a refrigeration mechanism 3 and a temporary cooling pipe 4;

[0033] The liquid cooling pipe 2 is divided into a core pipe 201 and an edge pipe 202. The middle positions of the core pipe 201 and the edge pipe 202 are connected to the temporary cooling pipe 4. The cooling liquid in the core pipe 201 is transported to the temporary cooling pipe 4 for cooling and then transported to the edge pipe 202.

[0034] An inlet pipeline 401 and a discharge pipeline 402 are respectively provided at both ends of the temporary cooling pipeline 4. A solenoid valve 403 is installed on the discharge pipeline 402. A temperature controller 404 for controlling the start and stop of the solenoid valve 403 is installed on the outside of the temporary cooling pipeline 4. After the solenoid valve 403 is opened, the coolant inside the inlet pipeline 401 gradually flows into the temporary cooling pipeline 4, forcing the high-temperature coolant in the temporary cooling pipeline 4 into the discharge pipeline 402.

[0035] In this embodiment, if Figure 1 and Figure 2 As shown, the core pipeline 201 is placed in the core area of ​​the battery pack to achieve centralized heat dissipation, while the edge pipeline 202 is arranged in the remaining area to provide auxiliary heat dissipation. The coolant in the core pipeline 201 is guided to flow to the temporary cooling pipe 4 for heat exchange and then discharged through the edge pipeline 202, thereby improving the overall heat dissipation efficiency.

[0036] In addition, a liquid inlet pipeline 401 and a liquid discharge pipeline 402 are added to the temporary cooling pipe 4, and the coolant just discharged from the refrigeration mechanism 3 is directly transported to the temporary cooling pipe 4 for storage through the liquid inlet pipeline 401. At the same time, a temperature controller 404 and a solenoid valve 403 for monitoring the temperature are added to monitor the coolant in the temporary cooling pipe 4 in real time, and automatically adjust the coolant in the temporary cooling pipe 4 according to temperature changes, so as to achieve the functions of low-temperature preservation and automatic replacement of coolant at high temperature, further ensuring the refrigeration effect of the temporary cooling pipe 4.

[0037] In this embodiment, if Figure 2 and Figure 3 As shown, at least two threaded pipes 203 are connected to the side curved surface in the middle of the core pipeline 201, and a bellows 204 is installed at the other end of each threaded pipe 203. The bellows 204 is in a compressed state under low temperature conditions, and a hose 205 connected to the edge pipeline 202 is provided at the end of the two bellows 204.

[0038] It should be noted that the openings at both ends of the core pipeline 201 are connected to the refrigeration mechanism 3, and two threaded tubes 203 with a smaller inner diameter are connected in the middle of the core pipeline 201 to divert the coolant in the core pipeline 201, ensuring that the coolant flows more evenly through the temporary cooling pipe 4, and fully exchanges heat with the coolant in the temporary cooling pipe 4, thereby improving the heat exchange efficiency and achieving rapid cooling. The number of threaded tubes 203 can be appropriately increased or decreased according to the power requirements of different battery packs. The bellows 204 and the hose 205 in a compressed state are connected to the ends of the threaded tubes 203, and are transported to the edge pipeline 202 through the bellows 204 and the hose 205.

[0039] In this embodiment, if Figure 2 and Figure 4 As shown, the bellows 204, the threaded tube 203, and the hose 205 are all placed inside the temporary cooling pipe 4. One end of the hose 205 extends to the outside of the temporary cooling pipe 4 and remains fixed in place. The shape of the bellows 204 changes according to the temperature of the coolant in the temporary cooling pipe 4.

[0040] Specifically, under normal operating conditions, when the temperature of the coolant in the temporary cooling pipe 4 is maintained within a preset range, the bellows 204 will be in a compressed state. In this state, it can quickly transport the coolant in the threaded tube 203 to the hose 205 and discharge it through the hose 205. Therefore, the coolant in the core pipeline 201 stays in the temporary cooling pipe 4 for a relatively short time, thereby achieving rapid circulation. Under high temperature conditions, the bellows 204 will automatically expand to increase its overall length, thereby extending the flow path of the coolant. This design allows the coolant in the core pipeline 201 to stay in the temporary cooling pipe 4 for a relatively long time under high temperature conditions, thereby improving the cooling efficiency.

[0041] In this embodiment, if Figure 6 and Figure 8 As shown, a sealing plug 405 is provided inside the drain pipe 402, and a spring 406 is connected to the other side of the sealing plug 405. After the coolant inside the temporary cooling pipe 4 enters the drain pipe 402, it pushes the sealing plug 405 to slide horizontally along the sealed cavity inside the drain pipe 402, accompanied by the compression of the spring 406.

[0042] A rack 5 is connected to the middle of the sealing plug 405 near the spring 406, and a gear 6 is engaged above the rack 5. A shift rod 7 is installed on the outside of the gear 6. The sealing plug 405 drives the rack 5 to slide, so that the gear 6 rotates, and further drives the shift rod 7 to rotate.

[0043] A layer of annular gasket 8 is provided on the outside of the shifting rod 7 , and the annular gasket 8 is embedded in the inner wall of the temporary cooling pipe 4 .

[0044] like Figure 7 As shown, the annular gasket 8 of the lever 7 is used to block the slide groove on the surface of the temporary cooling pipe 4. When the lever 7 rotates, the annular gasket 8 rotates synchronously to block the coolant in the temporary cooling pipe 4 to prevent it from leaking.

[0045] A shift block 206 is installed on the surface of the bellows 204. The shift block 206 is connected to the shift rod 7. The rotation of the shift rod 7 drives the shift block 206 to draw a circle, further driving the bellows 204 to stretch.

[0046] It should be noted that, by connecting the drain pipe 402 to the outlet of the temporary cooling pipe 4, the solenoid valve 403 is set at the outlet of the temporary cooling pipe 4. When the solenoid valve 403 is opened, the coolant in the temporary cooling pipe 4 flows to the drain pipe 402, squeezing the sealing plug 405 and the spring 406 in the drain pipe 402.

[0047] In this embodiment, if Figure 4 and Figure 8As shown, the sealing plug 405 and the rack 5 work together through a fixed connection. When the sealing plug 405 moves, the spring 406 on the back thereof is compressed, and the rack 5 and the sealing plug 405 slide synchronously, thereby driving the gear 6 and the lever 7 to rotate. The rotation of the lever 7 drives the lever block 206 to draw a circle, and further drives the bellows 204 to expand. During the expansion of the bellows 204, its overall length gradually increases. This process ensures that the coolant in the threaded tube 203 stays in the temporary cooling pipe 4 for a longer time.

[0048] In addition, when the liquid replacement in the temporary cooling pipe 4 is completed, the solenoid valve 403 remains closed, there is no continuous coolant replenishment in the discharge pipe 402, the liquid pressure gradually decreases, the spring 406 begins to squeeze the piston and gradually reset, and the remaining liquid in the discharge pipe 402 exerts a reverse force on the spring 406, effectively preventing the spring 406 from rebounding quickly.

[0049] A temperature sensor 407 is plugged into the top of the temperature controller 404 , and a probe of the temperature sensor 407 extends into the inlet of the drainage pipeline 402 .

[0050] The drain pipe 402 is connected to a recovery pipe 408 at a position away from the solenoid valve 403 , and the high-temperature coolant in the temporary cooling pipe 4 enters the recovery pipe 408 for recovery at the end of the sliding stroke of the sealing plug 405 .

[0051] It should be noted that the probe of the temperature sensor 407 is designed at the outlet of the temporary cooling pipe 4. The temperature sensor 407 collects the temperature of the coolant in the temporary cooling pipe 4 in real time, and transmits the collected value to the temperature controller 404. The electrical signal is transmitted to the solenoid valve 403 through the temperature controller 404 to control the start and stop of the solenoid valve 403. This solution belongs to the existing technology in this field. In this embodiment, the upper limit threshold of the temperature controller 404 is adjustable. When the temperature exceeds the upper limit threshold, the solenoid valve 403 opens.

[0052] In addition, it should be noted that the upper limit threshold of the temperature controller 404 should be set within the normal operating temperature range of the coolant. Specifically, the operating temperature range of the coolant is usually around 25°C to 55°C. Within this temperature range, the coolant can effectively absorb the heat generated by the battery pack. The threshold of the temperature controller 404 should be set to between 25°C and 55°C so as to trigger the temperature controller 404 to work in advance, open the solenoid valve 403, and replace the coolant in the temporary cooling pipe 4, ensuring that while the coolant in the temporary cooling pipe 4 is being replaced, the liquid in the threaded pipe 203 can also be continuously cooled, thereby avoiding ineffective cooling operations.

[0053] The refrigeration mechanism 3 includes a heat exchanger 301, the outlet of the heat exchanger 301 is connected to the liquid storage tank 302, the inlet of the heat exchanger 301 is connected to the recovery pipeline 408, the side wall of the liquid storage tank 302 is connected to the circulation pump 303, the outlet of the circulation pump 303 is connected to the four-way pipe 304, and the four-way pipe 304 is respectively connected to the core pipeline 201 and the liquid inlet pipeline 401.

[0054] It should be pointed out that the recovered high-temperature coolant is cooled by the heat exchanger 301 and stored in the liquid storage tank 302 to prepare for the next heat dissipation cycle. The coolant in the initial area is diverted by the four-way pipe 304, and a part of it is transported to the temporary cooling pipe 4 for temporary storage to prepare for temporary heat dissipation of the coolant flowing in the middle. Most of the coolant is concentrated to flow to the core pipeline 201 to cool the core area of ​​the battery pack. The temporary cooling pipe 4 can be made of thermal insulation material to avoid the internal coolant from cooling too quickly. Before the coolant temperature in the temporary cooling pipe 4 rises, there is no need to replace it. This achieves temporary heat dissipation without interfering with the liquid flow of the core pipeline 201.

[0055] Working principle: When using the integrated liquid cooling radiator of the new energy vehicle battery:

[0056] First, place the battery pack on top of the liquid cooling plate 1 and start the circulation pump 303. The circulation pump 303 draws the coolant from the liquid storage tank 302 and diverts it to the four-way pipe 304, dividing the coolant into three paths. One path passes through the liquid inlet pipe 401, which must be insulated and kept away from the high-temperature battery pack to ensure that the coolant flowing into the temporary cooling pipe 4 is at a low temperature. The other two paths flow to the two ends of the core pipe 201 until the temporary heat dissipation pipe is filled with coolant. At this time, all the coolant will be concentrated in the core pipe 201, flowing in from both ends of the core pipe 201, cooling the core area of ​​the battery pack, and then merging into the middle.

[0057] Then, the coolant flowing into the core pipe 201 gradually flows into the threaded pipe 203. At this time, the threaded pipe 203, the hose 205, and the bellows 204 are all immersed in the coolant in the temporary cooling pipe 4, cooling the high-temperature coolant flowing into the core pipe 201. The coolant then flows from the hose 205 to the edge pipe 202 to assist in cooling the rest of the power supply.

[0058] Secondly, as the battery pack continues to operate, the temperature of the coolant in the temporary cooling pipe 4 gradually increases. At this time, the overall temperature of the battery pack is high, which triggers the operation of the temperature controller 404 and the solenoid valve 403. The solenoid valve 403 opens, and under the pressure of the front-end circulation pump 303, the coolant in the temporary cooling pipe 4 gradually flows to the drain pipe 402, squeezing the sealing plug 405 and the rack 5 toward the gear 6. At this time, the rack 5 drives the gear 6 to rotate clockwise, driving the lever 7 to rotate clockwise, and the bellows 204 is expanded;

[0059] Next, after the bellows 204 is unfolded, the overall length of the threaded tube 203 and the bellows 204 is increased. At this time, the temperature of the coolant in the temporary cooling pipe 4 is still lower than the temperature of the coolant in the threaded tube 203. The flow path of the coolant is extended, so that the coolant in the bellows 204 and the threaded tube 203 can be further cooled.

[0060] Finally, as more and more new coolant is injected into the temporary cooling pipe 4, until the temperature is lower than the preset threshold of the temperature controller 404, the solenoid valve 403 is closed. As the solenoid valve 403 is closed, the liquid in the discharge pipe 402 gradually flows to the recovery pipe 408 and is recovered through the recovery pipe 408. When the hydraulic pressure is gradually less than the pressure of the spring 406, the spring 406 begins to slowly reset, driving the piston and rack 5 to reset, and the gear 6 begins to rotate counterclockwise, driving the bellows 204 to contract and reset, returning to normal state.

[0061] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
