Description

Technical Field

[0001] This invention relates to the field of battery pack temperature control technology, and in particular to a battery temperature control plate heat exchanger. Background Technology

[0002] In the current temperature control system of power batteries for new energy vehicles, heating and cooling generally adopt two independent temperature control circuits. Cooling relies on the refrigerant heat exchange circuit, while heating relies on the heater water circuit. The pipeline layout of the two systems is scattered, resulting in a large space occupation. This not only increases the difficulty of vehicle layout but also leads to higher system costs and failure rates.

[0003] At the same time, most of the existing plate heat exchangers are single-function, fixed flow channel structures, and can only achieve independent heat exchange operations of cooling or heating. Even if there are heat exchangers that can be integrated, it is difficult to make reasonable reuse of the idle flow channel area when not in operation.

[0004] When batteries require rapid cooling or heating, it is difficult to expand the flow channel area without increasing the heat exchange components. This makes it difficult for the heat exchange efficiency and temperature control response speed to meet the actual needs of rapid cooling and heating of power batteries. At the same time, the flow patterns of conventional heat exchangers are mostly fixed and non-adjustable, which results in low utilization of internal space. The cooling and heating areas are separated into two systems, making it difficult for them to work together. This limits the overall performance of the temperature control system and makes it difficult to adapt to the requirements of new energy vehicles for efficient, compact and stable temperature control of batteries. Summary of the Invention

[0005] Given the problem that the cooling and heating functions of automotive battery heat exchangers are independent in existing technologies, a battery temperature control plate heat exchanger is proposed.

[0006] Its purpose is to integrate heating and cooling into a single radiator, while utilizing unused flow channels to accelerate either cooling or heating.

[0007] The technical solution of this invention is a battery temperature-controlled plate heat exchanger, including a connecting assembly, which includes a connecting plate, and further includes heat exchange components symmetrically arranged on the connecting plate, a pressing assembly disposed on the outer wall of the heat exchange components and symmetrically arranged on both sides of the connecting plate, a pair of water pipes respectively fixedly disposed on the outer wall of the pressing assembly, refrigerant pipes symmetrically disposed on the outer wall of the pressing assembly and installed above the connecting plate, heater pipes symmetrically disposed on the outer wall of the pressing assembly and installed below the connecting plate, and a pressing frame fixedly disposed on the inner wall of the connecting plate. The assembly includes a servo motor fixedly mounted on the outer wall of the pressing frame and an adjustment component fixedly mounted on the output end of the servo motor; the connecting assembly also includes a fixed plate symmetrically fixedly mounted on the upper and lower inner walls of the connecting plate and through holes symmetrically opened on the outer wall of the fixed plate; the heat exchange assembly includes an A-type heat sink mounted on the outer wall of the connecting plate and a B-type heat sink mounted on the outer wall of the A-type heat sink; the pressing assembly includes a pressing plate fixedly mounted on the outer wall of the pressing frame, a cylinder fixedly mounted on the outer wall of the pressing plate, a movable component fixedly mounted on the output end of the cylinder, and a limiting component fixedly mounted on the inner wall of the pressing plate.

[0008] Furthermore, the movable component includes a connecting rod fixedly disposed at the cylinder output end, an extension plate fixedly disposed on the outer wall of the connecting rod, a connecting block symmetrically fixedly disposed on the outer wall of the extension plate, a limiting groove formed on the outer wall of the connecting block, and an insertion plate fixedly disposed on the outer wall of the connecting block.

[0009] Furthermore, the limiting component includes a connecting frame fixedly disposed on the inner wall of the pressing plate, a limiting strip fixedly disposed on the outer wall of the connecting frame, a damping rod symmetrically fixedly disposed on the inner side wall of the connecting frame, and a compression spring disposed on the outside of the damping rod.

[0010] Furthermore, the connecting block is slidably connected to the outer wall of the limiting strip via a limiting groove, and the outer wall of the insertion plate is slidably connected to the inner wall of the pressing plate.

[0011] Furthermore, the adjustment assembly includes a rotating wheel fixedly mounted on the output end of the servo motor, a transmission belt rolling on the outer wall of the rotating wheel, a first limiting post rolling on the outer wall of the transmission belt, a second limiting post rolling on the outer wall of the transmission belt, a rotating disk rolling on the outer wall of the transmission belt, a fixing plate fixedly mounted on the inner wall of the rotating disk, a rotating component rotatably mounted on the inner wall of the rotating disk, and a linkage gear rotatably mounted on the inner wall of the rotating disk.

[0012] Furthermore, the rotating component includes a rotating ring rotatably disposed on the inner wall of the rotating disk, rotating teeth fixedly disposed on the outer side wall of the rotating ring, and a flow guiding structure fixedly disposed on the inner side wall of the rotating ring.

[0013] Furthermore, the two ends of the first limiting post and the two ends of the second limiting post are fixedly connected to the inner wall of the rotating disk, and the outer wall of the rotating ring meshes with the outer wall of the linkage gear through rotating teeth.

[0014] Furthermore, the flow guiding structure includes an inclined strip fixedly disposed on the inner side wall of the rotating ring, a flow guiding groove formed on the outer wall of the inclined strip, and a flow splitting groove formed on the outer wall of the inclined strip.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By dividing the heat exchanger into upper and lower sections, cooling and heating zones are set up, integrating heating and cooling functions. Idle flow channels can be used as expansion channels, making full use of the internal space of the heat exchanger. The flow channel area can be doubled without increasing the heat exchange components, thereby improving the rapid cooling and rapid heating capabilities.

[0016] 2. When the medium flows through the rotating component, it can drive the rotating ring to rotate. In conjunction with the flow guide groove and the flow divider, it can effectively avoid fluid eddies, air blockage and uneven flow velocity. While reducing flow resistance, it can improve heat transfer uniformity and enhance the heat transfer effect by enhancing turbulence.

[0017] 3. The rotation of the rotating ring can disturb the fluid and reduce the adhesion and deposition of impurities, prevent flow channel blockage, extend the stable operation cycle of the heat exchanger, and improve the reliability and service life of the battery temperature control system.

[0018] 4. The use of pressing and adjusting components to achieve flow channel opening and closing and mode switching, and the plates being fixed by pressing, all make the internal state easy to observe, improving maintenance convenience while ensuring the structural strength of the heat exchanger.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figure 1 - Figure 13This first embodiment of the invention provides a battery temperature-controlled plate heat exchanger, including a connecting assembly 1. The connecting assembly 1 includes a connecting plate 11, a heat exchange assembly 2 symmetrically snapped onto the connecting plate 11, a pressing assembly 3 snapped onto the outer wall of the heat exchange assembly 2 and symmetrically installed on both sides of the connecting plate 11, a pair of water pipes 4 respectively fixedly connected to the outer wall of the pressing assembly 3, a refrigerant pipe 5 symmetrically fixedly connected to the outer wall of the pressing assembly 3 and installed above the connecting plate 11, a heater pipe 6 symmetrically fixedly connected to the outer wall of the pressing assembly 3 and installed below the connecting plate 11, a pressing frame 7 fixedly connected to the inner wall of the connecting plate 11, a servo motor 8 fixedly connected to the outer wall of the pressing frame 7, and an adjustment assembly 9 fixedly connected to the output end of the servo motor 8.

[0023] The connecting component 1 also includes a fixing plate 12 symmetrically fixedly connected to the inner walls of the upper and lower sides of the connecting plate 11, and through holes 13 symmetrically opened on the outer wall of the fixing plate 12.

[0024] The heat exchange assembly 2 includes an A-type heat sink 21 that is snapped onto the outer wall of the connecting plate 11 and a B-type heat sink 22 that is snapped onto the outer wall of the A-type heat sink 21.

[0025] The pressing assembly 3 includes a pressing plate 31 fixedly connected to the outer wall of the pressing frame 7, a cylinder 32 fixedly connected to the outer wall of the pressing plate 31, a movable part 33 fixedly connected to the output end of the cylinder 32, and a limiting part 34 fixedly connected to the inner wall of the pressing plate 31.

[0026] Specifically, during operation, the upper and lower areas of the connecting plate 11 naturally form a cooling area and a heating area. When the battery needs to be cooled, the pressing component 3 on one side of the refrigerant pipe 5 is activated, the cylinder 32 moves and drives the connecting rod 331 of the movable component 33 to move. The connecting rod 331 drives the extension plate 332 to move synchronously. The extension plate 332 drives the connecting block 333 and the insertion plate 335 to move. The connecting block 333 slides stably along the limiting strip 342 of the limiting component 34 through the limiting groove 334 on the outer wall. The insertion plate 335 then retracts into the pressing plate 31 and the connecting frame 341 and leaves the inlet and outlet position of the refrigerant pipe 5. At the same time, the connecting block 333 squeezes the damping rod 343 and the compression spring 344 to achieve buffering and positioning.

[0027] Reference Figure 1 - Figure 12 The movable component 33 includes a connecting rod 331 fixedly connected to the output end of the cylinder 32, an extension plate 332 fixedly connected to the outer wall of the connecting rod 331, a connecting block 333 symmetrically fixedly connected to the outer wall of the extension plate 332, a limiting groove 334 opened on the outer wall of the connecting block 333, and an insertion plate 335 fixedly connected to the outer wall of the connecting block 333.

[0028] Specifically, battery water flows in through the upper water pipe 4, passes through the pressing plate 31, and enters the gap between type A heat sink 21 and type B heat sink 22. Due to the concave-convex structure of type A heat sink 21 and type B heat sink 22 and the middle obstruction, the water first fills the lower channel, then flows along the gap between the outer convex side of type A heat sink 21 and the inner concave side of type B heat sink 22, and after passing through the middle obstruction position of the heat sink, it enters the flow channel on the other side. After continuing to flow through the lower heating area, it is discharged from the other water pipe 4. At the same time, refrigerant enters from the refrigerant pipe 5, which is not on the same side as the water pipe 4, and flows from the gap between the bottom end of the pressing plate 31 and the top of type A heat sink 21, as well as the gap between the inner concave side of type A heat sink 21 and the outer convex side of type B heat sink 22. After filling the heat exchange flow channel according to the same bypass path as the battery water, it is discharged from the other refrigerant pipe 5. The two fluids are completely isolated in the heat exchange area and achieve heat exchange.

[0029] Reference Figure 1 - Figure 13 The limiting component 34 includes a connecting frame 341 fixedly connected to the inner wall of the pressing plate 31, a limiting strip 342 fixedly connected to the outer wall of the connecting frame 341, a damping rod 343 symmetrically fixedly connected to the inner side wall of the connecting frame 341, and a compression spring 344 sleeved on the outside of the damping rod 343. The connecting block 333 is slidably connected to the outer wall of the limiting strip 342 through the limiting groove 334, and the outer wall of the insertion plate 335 is slidably connected to the inner wall of the pressing plate 31.

[0030] Specifically, the connecting block 333 slides stably along the limiting strip 342 through the limiting groove 334 on the outer wall, the insertion plate 335 retracts into the pressing plate 31 and the connecting frame 341 below, and the connecting block 333 squeezes the damping rod 343 and the compression spring 344 to complete the buffer positioning, ensuring that the pressing assembly 3 operates smoothly and reliably.

[0031] Example 2, refer to Figure 1 - Figure 16 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adjustment component 9 includes a rotating wheel 91 fixedly connected to the output end of the servo motor 8, a transmission belt 92 rollingly connected to the outer wall of the rotating wheel 91, a first limiting post 93 rollingly connected to the outer wall of the transmission belt 92, a second limiting post 98 rollingly connected to the outer wall of the transmission belt 92, a rotating disk 94 rollingly connected to the outer wall of the transmission belt 92, a fixing plate 95 fixedly connected to the inner wall of the rotating disk 94, a rotating component 96 rotatably connected to the inner wall of the rotating disk 94, and a linkage gear 97 rotatably connected to the inner wall of the rotating disk 94.

[0032] Specifically, when rapid cooling is required, the servo motor 8 is activated, which drives the rotating wheel 91 of the adjusting component 9 to rotate. The rotating wheel 91 drives the transmission belt 92 to move. Under the limiting tension of the first limiting post 93 and the second limiting post 98, the transmission belt 92 drives the rotating disk 94 to rotate 180 degrees, so that the rotating component 96 replaces the original fixed plate 95 and forms a complete communication area with the through hole 13 on the fixed disk 12 of the connecting component 1. At this time, the heating area below cannot drain water under the sealing effect of the pressing component 3. The flow channel where the heater tube 6 is located is only used as a refrigerant flow channel. Without increasing the heat exchange component 2, the cooling channel area is doubled, thereby achieving rapid cooling of the battery. When rapid heating is required, the servo motor 8 drives the rotating disk 94 to rotate, expanding the heating flow channel area to increase the heating speed. When rapid temperature control is not required, the rotating disk 94 is rotated back to its original position, so that the fixed plate 95 rotates to the position of the through hole 13 and closes the expanded channel.

[0033] Reference Figure 1 - Figure 14 The rotating component 96 includes a rotating ring 961 rotatably connected to the inner wall of the rotating disk 94, a rotating tooth 962 fixedly connected to the outer side wall of the rotating ring 961, and a flow guiding structure 963 fixedly connected to the inner side wall of the rotating ring 961. The two ends of the first limiting post 93 and the two ends of the second limiting post 98 are fixedly connected to the inner wall of the rotating disk 94. The outer wall of the rotating ring 961 meshes with the outer wall of the linkage gear 97 through the rotating tooth 962.

[0034] Specifically, when the medium flows through the rotating component 96, it is guided by the flow guiding structure 963 and driven by the fluid's own pressure to rotate the rotating ring 961. The rotating ring 961 drives the linkage gear 97 to rotate synchronously through the rotating teeth 962 on the outer wall, thereby driving the rotating rings 961 on both sides to rotate in the same direction.

[0035] Reference Figure 1 - Figure 16 The flow guiding structure 963 includes an inclined bar 9631 fixedly connected to the inner side wall of the rotating ring 961, a flow guiding groove 9632 opened on the outer wall of the inclined bar 9631, and a flow splitting groove 9633 opened on the outer wall of the inclined bar 9631.

[0036] Specifically, the opposite inclination directions of the two diagonal strips 9631 can accommodate different flow directions of the refrigerant and heating medium, ensuring that the two rotating rings 961 always rotate in the same direction. The guide grooves 9632 on the outer wall of the diagonal strips 9631 can guide the fluid to flow smoothly along a predetermined path, reducing flow resistance and improving heat transfer uniformity. The flow distribution grooves 9633 can evenly disperse the fluid to the entire flow channel cross-section, avoiding local eddies, air blockage, and uneven flow velocity. At the same time, the continuous rotation of the rotating rings 961 can disturb the fluid boundary layer, thereby increasing the heat transfer effect by enhancing turbulence, reducing the adhesion and deposition of impurities in the medium on the inner wall of the flow channel, preventing flow channel blockage, and extending the stable operation time of the heat exchanger. The overall structure maintains high strength under the support of the pressing frame 7, while realizing the functions of adjustable plates and easy observation of the internal state. The rest of the structure is the same as that of Embodiment 1.

[0037] Based on embodiments 1-2, the working principle of the present invention is as follows: During operation, the upper and lower areas of the connecting plate 11 naturally form a cooling area and a heating area. When the battery needs cooling, the pressing component 3 on one side of the refrigerant pipe 5 is activated, the cylinder 32 moves and drives the connecting rod 331 of the movable component 33 to move. The connecting rod 331 drives the extension plate 332 to move synchronously. The extension plate 332 drives the connecting block 333 and the insertion plate 335 to move. The connecting block 333 slides stably along the limiting strip 342 of the limiting component 34 through the limiting groove 334 on the outer wall. The insertion plate 335 then retracts into the pressing plate 31 and the connecting frame 341 and leaves the inlet and outlet position of the refrigerant pipe 5. At the same time, the connecting block 333 squeezes the damping rod 343 and the compression spring 344 to achieve buffering and positioning.

[0038] At this time, the battery water flows in from the upper water pipe 4, and passes through the pressing plate 31 into the gap between the type A heat sink 21 and the type B heat sink 22. Under the concave-convex structure of the type A heat sink 21 and the type B heat sink 22 and the middle obstruction, the water first fills the lower channel, and then flows along the gap between the outer convex side of the type A heat sink 21 and the inner concave side of the type B heat sink 22. After going around to the side close to the water pipe 4, it passes through the middle obstruction position of the heat sink and enters the flow channel on the other side. After continuing to flow through the lower heating area, it is discharged from the other water pipe 4. At the same time, the refrigerant enters from the refrigerant pipe 5, which is not on the same side as the water pipe 4. It flows from the gap between the bottom end of the pressing plate 31 and the top of the type A heat sink 21 and the gap between the inner concave side of the type A heat sink 21 and the outer convex side of the type B heat sink 22. After filling the heat exchange flow channel according to the same bypass path as the battery water, it is discharged from the other refrigerant pipe 5. The two fluids are completely isolated in the heat exchange area and achieve heat exchange.

[0039] When rapid cooling is required, the servo motor 8 is activated. The servo motor 8 drives the rotating wheel 91 of the adjusting component 9 to rotate. The rotating wheel 91 drives the transmission belt 92 to move. Under the limiting tension of the first limiting post 93 and the second limiting post 98, the transmission belt 92 drives the rotating disk 94 to rotate 180 degrees, so that the rotating component 96 replaces the original fixed plate 95 and forms a complete communication area with the through hole 13 on the fixed disk 12 of the connecting component 1. At this time, the heating area below cannot discharge water due to the sealing effect of the pressing component 3. The flow channel where the heater tube 6 is located only serves as... The refrigerant flow channel doubles the cooling channel area without increasing the heat exchange component 2, thus achieving rapid battery cooling. When the battery needs heating, the refrigerant pipe 5 is closed and the heater pipe 6 is opened. The hot water supplied by the heater enters the heat exchanger and exchanges heat with the battery water in an isolated manner. After heating the battery water, it is supplied to the battery to complete the heating. When rapid heating is required, the rotating disk 94 is driven to rotate by the servo motor 8 to expand the heating flow channel area and increase the heating speed. When rapid temperature control is not required, the rotating disk 94 is rotated back to its original position, causing the fixed plate 95 to rotate. When the medium flows through the through hole 13 and closes the expansion channel, it is guided by the flow guiding structure 963 and driven by the fluid's own pressure, pushing the rotating ring 961 to rotate. The rotating ring 961 drives the linkage gear 97 to rotate synchronously through the rotating teeth 962 on its outer wall, thereby driving the two rotating rings 961 to rotate in the same direction. The two inclined strips 9631 are inclined in opposite directions to adapt to the different flow directions of the refrigerant and heating medium, ensuring that the two rotating rings 961 always rotate in the same direction. The flow guiding grooves 9632 on the outer wall of the inclined strips 9631 can guide the fluid. The fluid flows smoothly along a predetermined path, reducing flow resistance and improving heat transfer uniformity. The flow divider 9633 can evenly distribute the fluid to the entire flow channel cross-section, avoiding problems such as local eddies, air blockage, and uneven flow velocity. At the same time, the continuous rotation of the rotating ring 961 can disturb the fluid boundary layer, thereby increasing the heat transfer effect by enhancing turbulence, reducing the adhesion and deposition of impurities in the medium on the inner wall of the flow channel, preventing flow channel blockage, and extending the stable operation time of the heat exchanger. The overall structure maintains high strength under the support of the pressing frame 7, while realizing the functions of adjustable plates and easy observation of the internal state.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
