Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, in particular to a novel high-power air-liquid cooling system. Background Art

[0002] As consumers' requirements for charging speed and driving range continue to increase, fast charging technology has become a new trend in the development of the new energy industry. In the context of the fast charging era, high charge and discharge rates have further increased the battery's dependence on thermal management systems.

[0003] As the mainstream battery cell of new energy, the existing technical means for cooling the square battery cell include single air cooling or liquid cooling.

Therefore, the existing technical means mostly adopt the combination of air and liquid, but the existing air and liquid heat dissipation are split, and the two sets of heat dissipation structures are not combined, so the improvement of heat dissipation effect is not obvious.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The utility model provides Figure 1-10 A novel high-power air-liquid cooling system shown in the figure comprises an upper shell 1, a liquid cooling mechanism is arranged at the bottom end of the upper shell 1, one end of the liquid cooling mechanism is arranged as a liquid inlet end, and the other end of the liquid cooling mechanism is arranged as a liquid discharge end, and the liquid cooling mechanism comprises:

[0041] Liquid cooling plate 2, the liquid cooling plate 2 is arranged at the bottom end of the upper shell 1, one end of the liquid cooling plate 2 is provided with a liquid inlet pipe 201, the other end of the liquid cooling plate 2 is provided with a liquid discharge pipe 202, the connecting structure and the air cooling mechanism are both arranged at the top of the liquid cooling plate 2 and located at one end close to the liquid discharge pipe 202;

[0042] It should be noted that, in the present embodiment, the liquid inlet pipe 201 and the liquid discharge pipe 202 are respectively arranged at the two ends of the liquid cooling plate 2. Through such an arrangement, a water inlet and outlet arrangement on the opposite sides is formed. When the liquid cooling plate 2 is used for heat dissipation, the coolant (such as a 50% ethylene glycol solution) is passed into the liquid cooling plate 2 through the liquid inlet pipe 201. At this time, the coolant flows from the liquid inlet end of the liquid cooling plate 2 to the liquid discharge end.

[0043] The liquid cooling plate 2 generally refers to a heat dissipation component used in a liquid cooling system, which is used to contact the CPU, GPU or other heat sources, and transfer heat to the coolant through a water cooling circulation system to achieve a heat dissipation effect. The liquid cooling plate 2 is usually made of metal, has high thermal conductivity, and can effectively transfer heat from the heat source to the coolant. The structure of the liquid cooling plate 2 generally includes corresponding structural parts, cooling channels and inlet / outlet pipes. The heat source (such as the CPU or GPU) contacts the liquid cooling plate 2 through the heat sink, and the heat is transferred to the coolant in the cooling channel, and then enters the liquid cooling plate 2 through the inlet pipe, takes away the heat after flowing in the cooling channel, and finally flows back to the radiator or other heat dissipation equipment through the outlet pipe for heat dissipation.

[0044] The thermally conductive gasket 204 is disposed on the top of the liquid cooling plate 2 , and the battery structure is disposed on the top of the thermally conductive gasket 204 .

[0045] It should be noted that the thermally conductive gasket 204 plays a role of heat conduction and insulation, and the battery structure is in contact with the liquid cooling plate 2 through the thermally conductive gasket 204, so that the generated heat is transferred to the liquid cooling plate 2 for heat dissipation.

[0046] Specifically, the battery structure includes:

[0047] The battery cells 4 are arranged in an array on the top of the thermally conductive pad 204, and the power supply ends of the battery cells 4 are connected in series and parallel through a plurality of bus bars 402;

[0048] PCB boards 401 , multiple PCB boards 401 are symmetrically arranged on the sides of the multiple battery cells 4 along the horizontal direction.

[0049] When the liquid cooling mechanism is working, the coolant is first introduced through the liquid inlet pipe 201, and the coolant circulates in the liquid cooling plate 2, and the coolant circulates toward the end close to the liquid discharge pipe 202. The heat generated at the bottom of the multiple battery cells 4 is first conducted to the thermal pad 204, and then the thermal pad 204 conducts heat through the top of the liquid cooling plate 2. At this time, the end of the liquid inlet pipe 201 in the liquid cooling mechanism is the cold end relative to the end of the liquid discharge pipe 202.

[0050] It should be noted that this step is a refrigeration principle step of the liquid cooling mechanism. This step is to maintain the low temperature of the liquid cooling plate 2 by flowing the coolant in the liquid cooling plate 2. The heat generated by the battery cell 4 is conducted to the thermal gasket 204, and then transferred to the liquid cooling plate 2 by the thermal gasket 204, and carried away by the coolant inside the liquid cooling plate 2.

[0051] It should be noted that the busbar 402 of the present solution refers to a conductive component that connects multiple battery cells 4 together. In a battery pack, multiple battery cells 4 can be connected in series or in parallel through the busbar 402 to achieve a larger capacity or higher voltage output. The busbar 402 is usually made of a material with good conductivity, such as copper or aluminum, to ensure the efficiency and safety of current transmission. Through the busbar 402, the battery cells 4 can effectively transfer charges to ensure that the entire battery pack can work properly.

[0052] In the configuration of this solution, some through holes are opened at one end of the upper shell 1, so that the charging and discharging interface and some connection ports of the battery structure can pass through these through holes and be exposed to the outside of the entire structure, so as to connect the entire battery when in use.

[0053] A battery structure is arranged at the top of the liquid cooling mechanism and inside the upper shell 1, an air cooling mechanism is arranged at the top of the liquid cooling mechanism and at its discharge end, a heat exchanger 6 is arranged at the air cooling mechanism, and a connecting structure is arranged between the heat exchanger 6 and the passage of the liquid cooling mechanism.

[0054] It should be noted that the heat exchanger 6 is a structure used for heat dissipation of the air cooling mechanism. In the structural design of the present scheme, the heat exchanger 6 is a tube-sheet structure. In this way, after the coolant is introduced into the heat exchanger 6, the heat exchange can be used to dissipate the heat of the air cooling mechanism. In the design of the present scheme, the coolant used in the heat exchanger 6 is connected to the liquid cooling mechanism through a connecting structure. In this way, when the coolant in the liquid cooling mechanism flows, it flows through the heat exchanger 6 through the connecting structure, thereby realizing series heat dissipation and saving parts.

[0055] The connectivity structure includes:

[0056] Connecting inserts 203, a plurality of connecting inserts 203 are symmetrically inserted and connected to one end of the top of the liquid cooling plate 2 near the drain pipe 202 along the horizontal and longitudinal directions;

[0057] The connecting conduits 602 are respectively sleeved on the tops of the connecting plugs 203 , and the ends of the connecting conduits 602 away from the connecting plugs 203 are respectively connected to the liquid inlet and outlet of the heat exchanger 6 .

[0058] It should be noted that when the connecting conduit 602 and the connecting insert 203 are inserted, it is necessary to ensure the sealing between the two, and a clamp or the like can be used for fixed connection to prevent leakage of the coolant during circulation.

[0059] When the coolant circulates in the liquid cooling plate 2, it passes through the guide between the connecting plug 203 and the connecting conduit 602 and circulates in the heat exchanger 6. At this time, the heat exchanger 6 keeps dissipating the heat of the battery cell 4 brought by the exhaust fan 7 to form cold air.

[0060] It should be noted that this step is a heat dissipation principle step of the exhaust fan 7. The heat exchanger 6 is attached to the motor end of the exhaust fan 7 and the forced convection of the exhaust fan 7 is used to transfer the heat absorbed by the battery cell 4 to the heat exchanger 6. The heat of the heat exchanger 6 is connected through the connecting pipe 203 and the connecting conduit 602. When the coolant in the liquid cooling plate 2 is circulated, the coolant can flow through the heat exchanger 6 to take away the heat. This can save the use of coolant. At the same time, the air cooling mechanism and the liquid cooling mechanism are combined together, so that the overall heat dissipation effect is more significantly improved.

[0061] A diverter device 3 for changing the air flow direction of the air cooling mechanism is arranged on the top of the battery structure.

[0062] Specifically, a protective plate 301 for adjusting the wind direction of the diverter device 3 is provided on one side of the multiple battery cells 4 and at one end close to the discharge pipe 202, and a baffle 302 for blocking the wind is provided on one side of the multiple battery cells 4 and at one end close to the inlet pipe 201. Its function is to ensure that the cold air is converted into hot air and returns to the diverter device 3 at the top of the battery cell 4 and flows out of the battery cell 4.

[0063] It should be noted that the reference Fig.13 and Fig.14 , the shunt device 3 is a continuous interval periodic structure, and the interval structure is divided into an air inlet channel and an air exhaust channel according to its function, and the two are arranged alternately. The cold air passes through the air inlet duct of the shunt device 3 from the top of the battery cell 4 into the air duct between the battery cells 4 formed by the gaps between the multiple battery cells 4. After passing through the air duct, the cold air absorbs the heat from the battery cell 4 and becomes hot air, and flows back to the air exhaust duct of the shunt device 3 on the top of the battery cell 4, and finally flows out of the battery cell 4, carrying the heat dissipated by the battery cell 4. The gaps between the multiple battery cells 4 (i.e., the air duct of the battery cell 4) are arranged orthogonally to the air inlet channel and the air exhaust channel formed by the shunt device 3, one above the other.

[0064] In addition, the diverter device 3 needs to use insulating materials or undergo insulation treatment, and its spacing structure setting can guide the wind direction of the air cooling mechanism, so that the heat dissipation path guidance and setting of the air cooling mechanism can be achieved through the diverter device 3. Therefore, the shape of the diverter device 3 can be determined according to the actual heat dissipation flow direction design. Through the setting of the diverter device 3, the wind entering the battery structure is redistributed to the corresponding flow direction, the wind flow stroke is increased, and the internal temperature is more uniform. It can be fixed on the top of the upper shell 1.

[0065] The wind enters from the air inlet channel, and is distributed into the air duct formed by the battery cells 4 at the bottom in a parallel air inlet manner. After a short journey, it flows back to the exhaust channel. According to the principle of heat transfer enhancement, the return process forms a "bend effect" to promote fluid disturbance. In addition, since the heat exchange journey of the wind is short, it can avoid the formation of a large thermal boundary layer that weakens heat transfer.

[0066] Specifically, the air cooling mechanism includes:

[0067] A mounting plate 5, the mounting plate 5 is disposed at the top of the liquid cooling plate 2 and is located near one end of the drain pipe 202;

[0068] Exhaust fan 7, multiple exhaust fans 7 are arranged horizontally and longitudinally between the mounting plate 5 and the heat exchanger 6, and the heat exchanger 6 is used to cool the hot air flow at the air inlet end of the exhaust fan 7. Both ends of the heat exchanger 6 are fixedly connected with connecting buckles 601, and one end of the multiple connecting buckles 601 away from the heat exchanger 6 is fixedly connected to the two ends of the mounting plate 5. The heat exchanger 6 and the mounting plate 5 are fixedly connected together through the fixed connection of the connecting buckles 601 and the mounting plate 5. At the same time, there is a gap between the heat exchanger 6 and the mounting plate 5 on the opposite side. The exhaust fan 7 is fixedly arranged in the gap. The heat of the battery cell 4 brought by the internal circulating wind passes through the heat exchanger 6 and becomes cold air. Under the action of the exhaust fan 7, the heat is blown into the air inlet channel of the diversion device 3. The air duct formed in the gap between the multiple battery cells 4 becomes hot air after heat exchange with the battery cells 4, and is discharged from the exhaust channel. Finally, it flows back to the heat exchanger 6 through the gap between the PCB board 401 and the side of the inner wall of the upper shell 1, and the reciprocating cycle is repeated to realize the cooling effect of the air cooling mechanism.

[0069] refer to Fig.11 When the air cooling mechanism is working, the exhaust fan 7 is started at the same time. The cold air cooled by the heat exchanger 6 is driven by the exhaust fan 7. The cold air is blown into the battery cell 4 from one end of the liquid cooling plate 2 close to the drain pipe 202. The cold air passes through the gaps between the multiple battery cells 4, absorbs the heat generated by the battery cells 4, and forms hot air. At the same time, the wind direction is guided by the shunt device 3, and the corresponding channel is isolated in the gap of the shunt device 3 for circulation. After the hot air flows out of the battery cell 4, it passes through the gap between the PCB board 401 and the inner wall side of the upper shell 1, and flows back to the heat exchanger 6 for cooling. This reciprocating cycle is repeated, and the multiple battery cells 4 are cooled by the circulation of air.

[0070] refer to Fig.12 If ventilation holes are respectively provided on both sides of the upper shell 1, the heat dissipation operation of the air cooling mechanism is to start the exhaust fan 7, and the cold air from the outside is accelerated to flow through the exhaust fan 7, and the cold air is blown to the inside of the battery cell 4 from the end of the liquid cooling plate 2 close to the discharge pipe 202. The cold air passes through the gaps between multiple battery cells 4, absorbs the heat generated by the battery cells 4, and forms hot air. At the same time, through the guidance of the diverter device 3, the wind direction is isolated in the gap of the diverter device 3 to circulate through the corresponding channel. After the cold air that absorbs the heat becomes hot air, it flows to the outside from the end of the liquid cooling plate 2 close to the liquid inlet pipe 201.

[0071] It should be noted that this step is a heat dissipation principle step of the air cooling mechanism. After the exhaust fan 7 is started in this step, the exhaust fan 7 drives the airflow to accelerate the flow. The airflow generated at this time is guided by the diversion device 3 to form a flow direction and form. Under the flow of airflow, the heat generated between the battery cells 4 will be taken away and discharged to dissipate heat. At the same time, during the continuous operation of the exhaust fan 7, the motor of the exhaust fan 7 will also generate heat.

[0072] It should be noted that the mounting plate 5 and the guard plate 301 are arranged horizontally in the vertical direction, and a gap is required between the two, so that the cold air generated by the rotation of the exhaust fan 7 can be introduced into the battery cell 4 by the diversion device 3 under the guidance, absorb the heat of the battery cell 4 and turn it into hot air, and flow back to the heat exchanger 6 through the air duct reserved between the PCB board 401 and the upper shell 1, and so on. The reciprocating cycle realizes the cooling effect of the air cooling mechanism. The wind after passing through the heat exchanger 6 is cold air, which is the cold end in the air cooling mechanism. At the same time, its flow direction is opposite to that of the liquid cooling mechanism, so that the overall heat dissipation process is evenly heated from top to bottom and from front to back.

[0073] Furthermore, a plurality of through holes are opened in the middle of the mounting plate 5, and the plurality of through holes correspond one by one to the plurality of exhaust fans 7 respectively. The through holes are used for exhausting air by the exhaust fans 7. A plurality of fixing plates 501 are fixedly connected to the bottom end of the mounting plate 5, and the fixing plates 501 are fixedly connected to the top end of the liquid cooling plate 2.

[0074] It should be noted that, through the setting of the through hole, the mounting plate 5 can block the exhaust fan 7. At the same time, through such a setting, the mounting plate 5 can be used to concentrate and guide the exhaust air of the exhaust fan 7. Through such a setting, the wind force of the exhaust fan 7 is more concentrated, thereby ensuring that the air cooling mechanism can be more effective and stable.

[0075] In the setting of this solution, the mounting plate 5 is fixed on the top of the liquid cooling plate 2 by means of the fixing plate 501. After the mounting plate 5 is set, the exhaust fan 7 can be stably set. In the setting of this solution, the exhaust fan 7 is fixedly connected between the heat exchanger 6 and the mounting plate 5 so that it can be stably set.

[0076] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or 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 protection scope of the present invention.
