Description

Technical Field

[0001] This invention relates to the field of liquid cooling plate technology for battery packs, specifically a uniform temperature liquid cooling plate. Background Technology

[0002] Battery packs are the core energy storage units for new energy vehicles, energy storage power stations, and other equipment. They are composed of multiple cells connected in series and parallel. Together with battery management systems and structural components, they realize the storage and output of electrical energy. The liquid cooling plate is the core heat exchange component of the battery pack's liquid cooling thermal management system. Through the circulation of coolant in the internal channels, it realizes the heat dissipation or preheating of the battery pack and maintains the cell temperature within the optimal operating range.

[0003] In traditional liquid cooling plates, over long-term use, machining debris, welding slag, and impurities in the coolant can easily clog narrow flow channels, leading to decreased heat dissipation efficiency and affecting the stable operation of the liquid cooling plate. Traditional liquid cooling plates lack coolant filtration. In liquid cooling plate systems, dissimilar metals such as the aluminum liquid cooling plate substrate, copper pipes / heat-conducting components, and steel fasteners come into contact. Coupled with the presence of the coolant (ethylene glycol-water solution, an electrolyte), galvanic corrosion is easily triggered. Static or slow-flowing coolant accelerates the accumulation of corrosion products on the inner walls of the pipes, leading to weld cracking and leakage over time. Galvanic corrosion is the process by which two metals with different electrode potentials come into contact in an electrolyte, and galvanic corrosion forms a spontaneous galvanic cell reaction. This causes the metal with the lower electrode potential (anode) to corrode faster, while the metal with the higher electrode potential (cathode) is protected. Galvanic corrosion can seriously affect the stable operation of equipment, leading to leakage of the liquid cooling plate. Summary of the Invention

[0016] The present invention has the following beneficial effects:

[0017] 1. This uniform temperature liquid cooling plate, through the impeller set in the inner cavity of the drive chamber, can rotate in the inner cavity of the drive chamber under the drive of the coolant, thereby driving the drive gear and transmission belt, and transmitting power to the driven gear, which in turn drives the drive worm and worm wheel, causing the rotating seat to rotate on the top of the top seat. Then, under the action of the connecting plate and the rotating plate, the impurities on the outer wall of the filter cartridge are treated, so that the filter cartridge has a continuous filtration effect on the coolant, avoiding blockage of the liquid cooling channel, and enabling the lower liquid cooling plate and the upper liquid cooling plate to operate stably.

[0018] 2. This uniform liquid cooling plate, through a driven shaft set on the outer wall of the drive gear, causes a cam to trigger a pressure switch as the driven shaft rotates. This triggers the pressure switch to generate an electrical signal. The operation of the equipment is monitored based on the voltage signal generated by the pressure switch per unit time. The rotation of the driven shaft drives the driven rod, causing the permanent magnet to rotate within the inner cavity of the magnetic core. The permanent magnet periodically cuts the coil on the magnetic core. According to the law of electromagnetic induction, the magnetic flux inside the coil on the magnetic core fluctuates periodically with the rotation of the permanent magnet, thus inducing an alternating current at the ends of the coil. When this alternating current flows through the coil, it forms an alternating rotating magnetic field around the coil. This magnetic field acts on the ions in the coolant, causing their movement to become irregular and turbulent. This prevents the smooth charge transfer between the aluminum anode lower liquid cooling plate and the copper cathode inlet pipe, thereby slowing down the rate of galvanic corrosion.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 - Figure 12 A uniform temperature liquid cooling plate includes a lower liquid cooling plate 1, an upper liquid cooling plate 2 installed on the top of the lower liquid cooling plate 1, a uniform temperature filling component 3 provided on the outer wall of the lower liquid cooling plate 1, a liquid cooling channel 4 and a liquid suction core 5 respectively provided in the inner cavity of the lower liquid cooling plate 1 with physical space isolation, and the liquid cooling channel 4 is arranged around the liquid suction core 5, an inlet pipe 6 is fixedly installed on the top of the upper liquid cooling plate 2, an outlet pipe 7 is fixedly installed on the top of the upper liquid cooling plate 2, a processing component 8 is provided on the top of the inlet pipe 6, and a control plate 9 is installed on the top of the upper liquid cooling plate 2.

[0036] In the above structure, the coolant is introduced into the inner cavity of the liquid cooling channel 4 provided in the inner cavity of the lower liquid cooling plate 1 and the upper liquid cooling plate 2 by the liquid cooling channel 4 under the action of the liquid inlet pipe 6. When the lower liquid cooling plate 1 and the upper liquid cooling plate 2 are installed below the battery pack, the heat generated by the operation of the battery pack is transferred downward to the coolant between the lower liquid cooling plate 1 and the upper liquid cooling plate 2. Then, the coolant with the increased temperature is released to the outside through the liquid outlet pipe 7. The temperature of the coolant is reduced by the external heat dissipation device, thereby achieving heat dissipation of the battery pack during the circulation of the coolant.

[0037] In a preferred embodiment: the uniform temperature filling assembly 3 includes a connecting pipe 301, a connecting seat 302 is fixedly mounted on the outer wall of the connecting pipe 301, a filling pipe 303 is fixedly mounted on the outer wall of the connecting pipe 301, a filling groove 304 is opened in the inner cavity of the filling groove 303, a limiting rod 305 is fixedly mounted on the inner wall of the filling groove 304, a moving plate 306 is movably sleeved on the outer wall of the limiting rod 305, a sealing plug 307 is fixedly mounted on the outer wall of the moving plate 306, and a driving spring 308 is movably sleeved on the outer wall of the limiting rod 305.

[0038] In the above structure, by using the liquid-absorbing core 5 installed in the inner cavity of the lower liquid cooling plate 1 and the upper liquid cooling plate 2, and the connecting pipe 301 installed on the outer wall of the lower liquid cooling plate 1, and injecting refrigerant into the connecting pipe 301, the refrigerant circulates through the liquid-absorbing core 5 in the inner cavity of the lower liquid cooling plate 1 and the upper liquid cooling plate 2 to undergo a gas-liquid two-phase change. During the gas-liquid phase change process, the latent heat storage and release characteristics allow for rapid absorption of local heat peaks and suppression of temperature fluctuations. At the same time, the overall temperature balance is maintained through the circulating heat exchange of the liquid cooling channel.

[0039] In a preferred embodiment: the two ends of the outer wall of the drive spring 308 are in contact with the outer wall of the moving plate 306 and the inner wall of the filling groove 304, respectively, and the drive spring 308 is made of high carbon steel. The outer wall diameter of the sealing plug 307 is smaller than the inner wall diameter of the filling groove 304, and the inner cavity of the connecting pipe 301 is connected to the inner cavity of the filling pipe 303.

[0040] In the above structure, when refrigerant needs to be added to the inner cavity of the connecting pipe 301, the filling pipe 303 provided on the outer wall of the connecting pipe 301 pushes the sealing plug 307 to move along the inner wall of the filling groove 304, and causes the moving plate 306 to slide along the outer wall of the limiting rod 305, and compresses the drive spring 308. When the sealing plug 307 moves inward to the position of the filling groove 304, the added refrigerant can pass through the gap between the sealing plug 307 and the filling groove 304 and enter the inner cavity of the connecting pipe 301, thereby entering the inner cavities of the lower liquid cooling plate 1 and the upper liquid cooling plate 2.

[0041] In a preferred embodiment: the processing component 8 includes a drive chamber 801, an impeller 802 is rotatably connected to the inner cavity of the drive chamber 801, a drive gear 803 is fixedly mounted at the end of the impeller 802, a guide tube 804 is fixedly mounted on the top of the drive chamber 801, a filter chamber 805 is installed on the top of the guide tube 804, a transmission belt 806 is rollably connected to the outer wall of the drive gear 803, and a top cover 8026 is installed on the top of the filter chamber 805.

[0042] In the above structure, through the drive chamber 801 set on the top of the liquid inlet pipe 6 and the impeller 802 set in the inner cavity of the drive chamber 801, coolant is continuously supplied to the inner cavity of the top cover 8026, the filter chamber 805 and the guide pipe 804 under the action of the external water pump. When the coolant passes through the guide pipe 804 and enters the inner cavity of the drive chamber 801, it can drive the impeller 802 under the action of the coolant flow, so that the impeller 802 rotates in the inner cavity of the drive chamber 801. During the rotation of the impeller 802, the drive gear 803 can be driven, and the rotational power of the drive gear 803 is transmitted under the action of the transmission belt 806.

[0043] In a preferred embodiment: a filter cylinder 808 is installed in the inner cavity of the filter chamber 805, a top seat 807 is installed on the top of the filter cylinder 808, a rotating seat 809 is rotatably connected to the top of the top seat 807, a worm gear 8010 is fixedly mounted on the top of the rotating seat 809, a connecting plate 8011 is fixedly mounted on the outer wall of the rotating seat 809, a cleaning brush 8012 is installed on the outer wall of the connecting plate 8011, a rotating plate 8013 is installed on the outer wall of the rotating seat 809, a magnetic plate 8014 is fixedly mounted on the outer wall of the rotating plate 8013, a drive worm 8015 is rotatably connected to the inner cavity of the filter chamber 805, and a driven gear 8016 is fixedly mounted at the end of the drive worm 8015.

[0044] In the above structure, the filter cylinder 808 installed in the inner cavity of the filter chamber 805 filters the coolant entering the inner cavity of the filter chamber 805. The coolant must pass through the outer wall of the filter cylinder 808 to enter the inner cavity of the guide tube 804. During the filtration process of the coolant by the filter cylinder 808, the machining debris, welding slag, and impurities in the coolant are blocked on the outer wall of the filter cylinder 808. Under the power transmission of the drive belt 806 to the drive gear 803, the driven gear 8016 and the drive worm 8015 rotate synchronously. Under the action of the drive worm 8015, the worm wheel 8010 is driven so that the rotating seat 809 rotates on the top of the top seat 807, thereby driving the connecting plate 8011 and the rotating plate 8013 to rotate on the outer wall of the filter cylinder 808.

[0045] In a preferred embodiment: a driven shaft 8017 is fixedly mounted on the outer wall of the drive gear 803, a cam 8018 is mounted on the outer wall of the driven shaft 8017, a pressure switch 8019 is fixedly mounted on the outer wall of the drive chamber 801, a first bevel gear 8020 is fixedly mounted on the end of the driven shaft 8017 away from the drive gear 803, a support frame 8021 is mounted on the top of the upper liquid cooling plate 2, a driven rod 8022 is rotatably connected to the inner cavity of the support frame 8021, a second bevel gear 8023 is mounted on the top of the driven rod 8022, a magnetic core 8024 is mounted on the top of the upper liquid cooling plate 2, and a permanent magnet 8025 is fixedly mounted on the bottom of the driven rod 8022;

[0046] In the above structure, the driven shaft 8017 is mounted on the outer wall of the drive gear 803, and the cam 8018 is mounted on the outer wall of the driven shaft 8017. As the impeller 802 rotates, the driven shaft 8017 also rotates synchronously, thereby driving the cam 8018 to rotate. When the cam 8018 rotates one revolution, it strikes the pressure switch 8019 once, generating a pressure signal. As the impeller 802 continues to rotate, it continuously generates striking signals. If a leak occurs at the connection between the lower liquid cooling plate 1 and the upper liquid cooling plate 2, resulting in a reduction in the total amount of coolant, When the coolant pumped by the water pump drops, it causes air to be contained inside, which in turn affects the drive of the impeller 802, causing the impeller 802 to rotate slower. At this time, the knocking signal generated by the pressure switch 8019 will decrease within a certain period of time, indicating that the equipment is malfunctioning or that there is severe blockage on the outer wall of the filter cartridge 808, preventing the coolant from passing through the filter cartridge 808 normally. This will also reduce the amount of coolant entering the inner cavity of the drive chamber 801 within a certain period of time, which will also reduce the rotational speed of the impeller 802. This also serves as a reminder to the user that the equipment has malfunctioned and needs to be repaired in a timely manner.

[0047] In a preferred embodiment: the inner walls on both sides of the transmission belt 806 mesh with the outer walls of the drive gear 803 and the driven gear 8016 respectively; the outer wall of the cleaning brush 8012 contacts the outer wall of the filter cartridge 808; and the outer wall of the drive worm 8015 meshes with the outer wall of the worm wheel 8010.

[0048] In the above structure, the transmission belt 806, which is provided on the outer wall of the drive gear 803, rotates synchronously with the rotation of the drive gear 803. This drives the driven gear 8016, which in turn drives the drive worm gear 8015. Since the drive worm gear 8015 meshes with the worm wheel 8010, the rotating seat 809 rotates on the top of the top seat 807, causing the cleaning brush 8012 to move along the outer wall of the filter cylinder 808, thus cleaning the outer wall of the filter cylinder 808. The magnetic plate 8014 rotates with the rotating seat 809, and under the action of the magnetic plate 8014, it adsorbs the metal impurities brushed off the filter cylinder 808 by the cleaning brush 8012, achieving a better cleaning effect.

[0049] In a preferred embodiment: the inner cavity of the top cover 8026 is connected to the inner cavity of the filter chamber 805, the inner cavity of the guide tube 804 is connected to the inner cavities of the drive chamber 801 and the filter chamber 805 respectively, and the cleaning brush 8012 is made of stainless steel.

[0050] In the above structure, the cleaning brush 8012 installed on the outer wall of the connecting plate 8011 causes the connecting plate 8011 to rotate along the outer wall of the filter cylinder 808 as the rotating seat 809 rotates. During the rotation of the connecting plate 8011, the cleaning brush 8012 continuously brushes the outer wall of the filter cylinder 808, thereby cleaning the outer wall of the filter cylinder 808 and preventing impurities from clogging the outer wall of the filter cylinder 808, thus affecting the normal flow of coolant.

[0051] In a preferred embodiment: the outer wall of the cam 8018 contacts the top of the pressure switch 8019, and the outer wall of the first bevel gear 8020 meshes with the outer wall of the second bevel gear 8023.

[0052] In the above structure, the first bevel gear 8020 set on the outer wall of the driven shaft 8017 and the second bevel gear 8023 set on the top of the driven rod 8022 can drive the second bevel gear 8023 synchronously during the rotation of the first bevel gear 8020. This causes the second bevel gear 8023 to drive the rotation of the driven rod 8022, which in turn causes the driven rod 8022 to rotate continuously in the inner cavity of the support frame 8021. This, in turn, causes the permanent magnet 8025 to rotate in the inner cavity of the magnetic core 8024, thereby continuously generating an alternating rotating magnetic field. This alternating rotating magnetic field then diffuses downwards into the inner cavities of the lower liquid cooling plate 1 and the upper liquid cooling plate 2.

[0053] In a preferred embodiment: the permanent magnet 8025 enters the inner cavity of the magnetic core 8024, and the permanent magnet 8025 is a neodymium iron boron magnet; the pressure switch 8019 is electrically connected to the control board 9.

[0054] In the above structure, the magnetic core 8024 set on the top of the upper liquid cooling plate 2 will synchronously drive the permanent magnet 8025 to rotate during the rotation of the driven rod 8022. Under the action of the rotation of the permanent magnet 8025, the permanent magnet 8025 will periodically cut the coil on the magnetic core 8024. According to the law of electromagnetic induction, the magnetic flux in the coil on the magnetic core 8024 will change periodically with the rotation of the permanent magnet 8025. An alternating induced current will be induced at both ends of the coil. When the induced current flows through the coil, an alternating rotating magnetic field will be generated around the coil. This magnetic field diffuses into the inner cavity of the lower liquid cooling plate 1 and the upper liquid cooling plate 2, and acts on the ions in the coolant and the metal pipe wall, thereby slowing down the electrochemical corrosion between the lower liquid cooling plate 1 and the upper liquid cooling plate 2 and extending the service life of the equipment.

[0055] Working principle: During use, the above-mentioned equipment combines the lower liquid cooling plate 1 and the upper liquid cooling plate 2, and supplies coolant to the inner cavities of the lower liquid cooling plate 1 and the upper liquid cooling plate 2 under the action of an external water pump. The coolant cools the battery pack surrounding the lower liquid cooling plate 1 and the upper liquid cooling plate 2. After the coolant enters the inner cavity of the filter chamber 805, it passes through the outer wall of the filter cylinder 808, where it is filtered, separating impurities in the coolant onto the outer wall of the filter cylinder 808. The coolant then passes through the filter cylinder 808 into the inner cavity of the guide tube 804 and continues to flow downwards into the inner cavity of the drive chamber 801, driving the impeller 802. The impeller 802 drives the drive gear 803 to rotate, thereby driving the transmission belt 806. The transmission belt 806 then... The power of the drive gear 803 is transmitted upward to drive the driven gear 8016, causing the drive worm 8015 to rotate in the inner cavity of the filter chamber 805. Since the outer wall of the drive worm 8015 meshes with the outer wall of the worm wheel 8010, the worm wheel 8010 and the rotating seat 809 rotate on the top of the top seat 807, thereby driving the connecting plate 8011 and the rotating plate 8013 to move along the outer wall of the filter cylinder 808. Under the action of the cleaning brush 8012, the outer wall of the filter cylinder 808 is cleaned, and the impurities attached to the outer wall of the filter cylinder 808 are scraped off, so that the metal impurities are detached from the filter cylinder 808 and placed in the gap between the filter cylinder 808 and the filter chamber 805. Then, during the movement of the magnetic plate 8014, the metal impurities brushed off are adsorbed, ensuring that the filter cylinder 808 can continuously filter the coolant.

[0056] As the impeller 802 continues to rotate, the drive gear 803 synchronously drives the driven shaft 8017 to rotate, which in turn drives the cam 8018 to rotate. When the cam 8018 completes one revolution, it will strike the pressure switch 8019 once, generating a voltage signal. As the impeller 802 continues to rotate, the pressure switch 8019 will continuously output voltage signals. If a leak occurs at the connection between the lower liquid cooling plate 1 and the upper liquid cooling plate 2 of the component, the total amount of coolant will decrease, and the amount of coolant sucked into the water pump will decrease accordingly. This will cause air to mix into the pump body, affecting the normal flow of coolant and causing the impeller 802 to rotate at a lower speed. This is reflected in the signal level as a decrease in the frequency of the voltage signal generated by the strike of the pressure switch 8019 per unit time. Based on this, it can be determined that the equipment is malfunctioning.

[0057] In addition, if the outer wall of the filter cartridge 808 is severely blocked, the coolant cannot pass through the filter cartridge 808 smoothly, which will result in insufficient coolant entering the inner cavity of the drive chamber 801. This will also cause the impeller 802 to rotate at a lower speed. The change in signal frequency can promptly remind the user that there is a fault in the equipment and that maintenance is required.

[0058] As the impeller 802 continues to rotate, it drives the driven shaft 8017, which in turn drives the first bevel gear 8020 to drive the second bevel gear 8023. This causes the driven rod 8022 to rotate within the cavity of the support frame 8021. During the rotation of the driven rod 8022, the permanent magnet 8025 is synchronously driven to rotate as well. In this process, the permanent magnet 8025 can periodically cut the coil on the magnetic core 8024. According to the law of electromagnetic induction, the magnetic flux inside the coil on the magnetic core 8024 will fluctuate periodically with the rotation of the permanent magnet 8025, thus inducing an alternating current at the ends of the coil. When the alternating current flows through the coil, it creates an alternating rotating magnetic field around the coil. This magnetic field diffuses into the inner cavities of the lower liquid cooling plate 1 and the upper liquid cooling plate 2, affecting the ions in the coolant and the metal pipe walls. This causes the movement of ions in the coolant to become irregular and chaotic, preventing smooth charge transfer between the aluminum lower liquid cooling plate 1 (anode) and the copper inlet pipe 6 (cathode). Furthermore, the constantly changing polarity of the alternating magnetic field repeatedly alters the direction of force on the ions, further disrupting the stability of ion migration. This interference makes it difficult for anode metal ions to continuously dissolve into the coolant, and the cathode cannot stably complete the reduction reaction of oxidizing substances, thus significantly slowing down the galvanic corrosion reaction rate and extending the service life of the lower liquid cooling plate 1 and the upper liquid cooling plate 2.
