Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Weight has been the most interesting point for various types of aircraft for the aerospace field. Lighter weight products mean that the aircraft can have a greater cargo capacity or a greater man-carrying capacity at the same weight standard. Taking the eVTOL electric vertical take-off and landing aircraft as an example, lighter aircraft also represents that it requires less power output during take-off and landing or flight, which enables longer output times for batteries of the same charge and longer endurance mileage for the aircraft. On the other hand, less power output means that noise generated by the propeller is reduced, so that eVTOL has the advantage of low-altitude running and improves the acceptance of the masses.
The energy of the eVTOL aircraft comes from the energy supply of the battery module 200, and the current thermal management system of the battery module 200 adopts a liquid cooling scheme, that is, a liquid cooling plate is placed inside the battery module 200 to cool the battery module, and a liquid cooling pipe is used to lead the cooling liquid out of the battery module 200, so that the whole aircraft needs to be equipped with a corresponding environmental control system (that is, a water pump, a water tank, a compressor, a condenser, an evaporator and the like) to perform proper temperature treatment on the cooling liquid. In combination with the location of the battery module 200 in the whole machine in practical situations, the lengthy liquid cooling pipeline design inevitably results in higher weight of the cooling liquid, and the corresponding matched environmental control equipment makes the weight of the whole machine battery thermal management system high. It follows that liquid-cooled heat dissipation systems are not fully compatible with the needs of the eVTOL industry. By analyzing the actual flight conditions of the eVTOL aircraft, it can be found that the heat accumulation of the battery module 200 is mainly concentrated in the aircraft suspension and landing stage, but in the flat flight process with a larger duty cycle in the flight conditions, the situation of high heat generation does not exist. Meanwhile, in the flight process of the aircraft, high-speed air flow can be formed by rotation of the propeller and incoming flow generated in the flat flight process, and if the air flow can be fully utilized, a large amount of heat generated in the vertical lifting process of the battery module 200 can be gradually dissipated in the flat flight process.
Therefore, the application provides a battery module and an aircraft adapting to an air-cooled heat dissipation system, and the heat conducting plate 230 and two side walls are combined to form the frame structure of the battery module 200, namely, the outer box structure of the battery module 200 with heavy weight in the related art is eliminated, so that the weight is reduced. Meanwhile, the battery cell 240 of the battery module 200 is arranged between the heat-conducting plates 230, and at least one side surface of the battery cell 240 and the corresponding side wall form a heat dissipation air channel which is communicated with the air cooling channel 12 of the machine body 10 and is not blocked by the outer box body of the battery module 200, so that high-speed air flow generated in the flight of an aircraft is directly introduced into the battery cell 240 to take away heat generated by the battery cell 240. Thus, the embodiment of the application provides a battery module 200 structure with lighter weight and higher heat dissipation efficiency.
The inventive concept of the present application will be further elucidated with reference to a few specific embodiments.
Referring to fig. 1, the present embodiment provides a battery module adapted to an air-cooled heat dissipation system. The battery module 200 includes: the first side wall 210 and the second side wall 220 are opposite and are arranged at intervals, a plurality of heat-conducting plates 230 and a plurality of battery cells 240.
Wherein, a side wall of the first side wall 210, which is away from the second side wall 220, is provided with a first battery module mounting structure, and/or a side wall of the second side wall 220, which is away from the first side wall 210, is provided with a second battery module mounting structure; the heat conducting plates 230 are arranged between the first side wall 210 and the second side wall 220, one end of each heat conducting plate 230 is connected with the first side wall 210, the other end of each heat conducting plate 230 is connected with the second side wall 220, and the plurality of heat conducting plates 230 are sequentially arranged at intervals so as to form a plurality of electric core chambers between the first side wall 210 and the second side wall 220; the battery cell 240 is disposed in the battery cell chamber, and at least one side surface of the battery cell 240 and the first side wall 210 or the second side wall 220 are spaced apart from each other to form a heat dissipation air channel.
Specifically, in the present embodiment, the frame structure of the battery module 200 is composed of the heat conductive plate 230, the first side wall 210, and the second side wall 220. The first side wall 210 and the second side wall 220 are opposite to each other and are spaced apart, so that they have inner side walls opposite to each other and also have outer side walls opposite to each other. And the outer sidewall of the first side wall 210 is provided with a first battery module mounting structure for mounting the battery module 200 on the body 10. The first battery module mounting structure may be a plurality of lug structures protruding from the outer sidewall of the first side wall 210, and during specific mounting, the lug structures may be fixed on the machine body 10 by using a fastening assembly such as a bolt or a screw, so as to fix the first side wall 210 on the machine body 10. Similarly, the second battery module mounting structure 221 may be a plurality of lug structures protruding from the outer sidewall of the second side wall 220, and in specific mounting, the lug structures may be fixed on the machine body 10 by using a fastening assembly such as a bolt or a screw, so as to fix the second side wall 220 on the machine body 10. Of course, the first battery module mounting structure and the second battery module mounting structure 221 may also be configured as other parts fixing and mating structures such as a latch, and the comparison of the present embodiment is not limited.
The first and second side walls 210 and 220 may be constructed in a plate-shaped structure, and may be also constructed in a box-shaped structure, which is not limited in this embodiment.
As can be seen, the present embodiment eliminates the outer case structure of the battery module 200, transfers the mounting structure to the first side wall 210 and/or the second side wall 220, provides assembly feasibility for directly mounting the battery module 200 on the machine body 10, and also significantly reduces the weight of the battery module 200.
In addition, in the present embodiment, the internal structural support of the battery module 200 is provided by a plurality of heat conductive plates 230. Specifically, the heat conductive plate 230 may be configured as an oblong heat pipe, an aluminum plate, or the like. The heat conducting plate 230 is disposed between the first side wall 210 and the second side wall 220, and one end of the heat conducting plate 230 is fixedly connected with the inner side wall of the first side wall 210, and a specific fixing connection manner may be welding or bonding. The other end of the heat conductive plate 230 is fixedly coupled to the inner sidewall of the second sidewall. Because both ends of the plurality of heat-conducting plates 230 are fixedly connected with the first side wall 210 and the second side wall 220, the plurality of heat-conducting plates 230, the first side wall 210 and the second side wall 220 can form a frame structure with a stable structure. And a space for installing the power core 240, i.e., a power core chamber, is formed between the plurality of heat conductive plates 230. Of course, in order to reduce the size, a plurality of heat conductive plates 230 are arranged in parallel with each other.
It can be appreciated that in this embodiment, the side wall assembly of the battery module 200 may be composed of the heat conducting plates 230 at the outermost sides of the two ends, the first side wall 210 and the second side wall 220, that is, the outermost heat conducting plates 230 are directly used as side walls, so that two side walls in the arrangement direction of the heat conducting plates 230 are omitted, and the overall weight of the battery module 200 is further reduced.
The battery cell 240 is mounted within the battery cell chamber, and at least one side surface of the battery cell 240 is spaced apart from the corresponding first side wall 210 or second side wall 220. That is, even though the battery cell 240 is spaced apart from the inner sidewall of the first side wall 210, or the battery cell 240 is spaced apart from the inner sidewall of the second side wall 220, or both the battery cell 240 and the inner sidewall of the first side wall 210 and the battery cell 240 and the inner sidewall of the second side wall 220 are spaced apart, a heat dissipation path penetrating the battery module 200 is formed to increase the heat dissipation contact area of the heat dissipation path and the battery cell 240. And a plurality of heat dissipation channels are formed in the battery module 200, and each heat dissipation channel is in direct contact with the battery cell 240, so that high-speed air flow can be directly introduced into the battery module 200, and heat dissipation can be performed by fully utilizing the high-speed air flow. On the other hand, in the present embodiment, the heat dissipation fins of the air cooling system, that is, the heat conduction plates 230 are directly connected with the first side wall 210 and the second side wall 220, and under the same external dimension condition as the prior art, the contact area between each heat conduction plate 230 and the high-speed air flow is larger, so that the heat dissipation efficiency can be improved.
It will be appreciated that in this embodiment, the heat-conducting plate 230 and the two side walls together form the frame structure of the battery module 200, i.e., the outer case structure of the battery module 200 having a relatively heavy weight in the related art is eliminated, thereby reducing the weight. Meanwhile, the battery cell 240 of the battery module 200 is arranged between the heat-conducting plates 230, and at least one side surface of the battery cell 240 and the corresponding side wall form a heat dissipation air channel which is communicated with the air cooling channel 12 of the machine body 10 and is not blocked by the outer box body of the battery module 200, so that high-speed air flow generated in the flight of an aircraft is directly introduced into the battery cell 240, and the efficiency of heat generated by the battery cell 240 is improved.
Specifically, the cell 240 generally includes 6 faces: left and right large faces, front and rear side faces and upper and lower end faces. In a possible embodiment, the large surface of the battery cell 240 is connected to the heat conducting plate 230 to increase the contact area between the battery cell 240 and the heat conducting plate 230, so as to conduct the heat of the battery cell 240 from the inside to the two ends of the heat conducting plate 230, and make the heat conducting plate 230 form fin-type heat dissipation structures on the two sides of the battery cell 240, so as to promote the sufficient heat dissipation of the battery cell 240. Of course, the large-surface connection of the heat conductive plate 230 and the battery cell 240 may also make the overall structure of the battery module 200 more compact.
In a possible embodiment, the battery cells 240 are in one-to-one correspondence with the battery cell chambers; the battery cell 240 is provided with a first heat-conducting medium layer 270a on one side, one side of the first heat-conducting medium layer 270a away from the battery cell 240 is connected with one of the two adjacent heat-conducting plates 230, the other side of the battery cell 240 is provided with a second heat-conducting medium layer 270b on the other side, and one side of the second heat-conducting medium layer 270b away from the battery cell 240 is connected with the other of the two adjacent heat-conducting plates 230.
Specifically, referring to fig. 2, in this embodiment, one battery cell 240 is disposed in each battery cell chamber, so that two large faces of a single battery cell 240 are respectively connected to two heat conducting plates 230, so that heat dissipation can be performed on each battery cell 240 sufficiently. And each cell chamber is provided with only one cell 240, so that more heat conducting plates 230 can be installed for the battery modules 200 with the same number of cells 240, thereby not only increasing the overall structural strength of the battery modules 200, but also improving the heat dissipation capability.
In addition, in the present embodiment, a heat conducting medium layer formed by heat conducting glue is provided between the large faces of the heat conducting plate 230 and the battery cell 240, so as to further improve the heat transfer efficiency between the large faces of the heat conducting plate 230 and the battery cell 240, and improve the heat dissipation efficiency.
Alternatively, in a possible further embodiment, each cell compartment is provided with two cells 240; a heat insulation medium layer 280 is arranged between the large faces of the opposite sides of the two battery cells 240; the large sides of the two battery cells 240 facing away from each other are respectively provided with a third heat conducting medium layer 270c, and the side wall of the third heat conducting medium layer 270c facing away from the battery cells 240 is connected with the heat conducting plate 230.
Specifically, referring to fig. 3, in the present embodiment, two electric cores 240 are disposed in each electric core chamber, that is, one of the adjacent heat conductive plates 230 is disposed with a first electric core 240, the first electric core 240 is disposed with a second electric core 240, and the second electric core 240 is connected with the other of the adjacent heat conductive plates 230.
At this time, a heat conducting medium layer formed of a heat conducting glue is provided between the large surface of each cell 240 and the heat conducting plate 230, so as to further improve the heat transfer efficiency between the heat conducting plate 230 and the large surface of the cell 240, thereby improving the heat dissipation efficiency. And an insulating medium layer 280 formed by an insulating medium such as aerogel is arranged between the two battery cells 240 so as to form thermal runaway protection between the two battery cells 240. That is, in this embodiment, the electric cells 240 can exchange heat with the heat-conducting medium only on one side, and the thermal runaway between the electric cells 240 is delayed by the heat-insulating medium layer 280 on the other side.
In a possible embodiment, the battery module 200 further includes: the third side wall 250 and the fourth side wall 260 are opposite and are arranged at intervals, the third side wall 250 and the fourth side wall 260 are arranged between the first side wall 210 and the second side wall 220, and the first side wall 210, the third side wall 250, the second side wall 220 and the fourth side wall 260 are sequentially enclosed to form a closed structure.
The plurality of heat conductive plates 230 are sequentially spaced apart from each other in a direction from the third side wall 250 to the fourth side wall 260 to form a plurality of cell chambers with the third side wall 250 and the fourth side wall 260, and the heat conductive plate 230 located at the outermost side is spaced apart from the corresponding third side wall 250 or fourth side wall 260.
Specifically, referring to fig. 4, in the present embodiment, the first side wall 210, the third side wall 250, the second side wall 220 and the fourth side wall 260 jointly enclose a closed structure, that is, jointly form a side wall assembly of the battery module 200. At this time, a battery cell accommodating cavity is defined in the side wall assembly, and a plurality of heat conducting plates 230 sequentially arranged along the directions from the third side wall 250 to the fourth side wall 260 are arranged in the battery cell accommodating cavity to divide the battery cell accommodating cavity into a plurality of battery cell chambers.
It should be noted that, in the present embodiment, in the directions from the third side wall 250 to the fourth side wall 260, the first heat conducting plate 230 and the third side wall 250 of the plurality of heat conducting plates 230 are opposite to and spaced apart from each other to form a first reserved gap. And the last heat conductive plate 230 and the fourth side wall 260 of the plurality of heat conductive plates 230 are opposite to and spaced apart from each other in the direction of the third side wall 250 to the fourth side wall 260 to form a second reserve gap.
The first and second reserved gaps may absorb the tolerance of the battery module 200 during manufacturing, may be used as a reserved buffer space for the expansion of the battery cell 240, or may be used as a reserved space for a temperature sampling point and/or a voltage sampling point.
Of course, in possible embodiments, the third side wall 250 may be tightly attached to the first heat conductive plate 230, and/or the fourth side wall 260 may be tightly attached to the last heat conductive plate 230, so as to provide sufficient strength support for the heat conductive plate 230, thereby improving the overall structural strength of the battery module 200.
In addition, in this embodiment, the third side wall 250 and the fourth side wall 260 may be configured as plate-shaped structures or box structures, and adjacent side walls are fixedly connected by welding, screwing components, or the like. Of course, as an embodiment, first side wall 210, second side wall 220, third side wall 250 and fourth side wall 260 may also be integrally formed, thereby achieving better structural strength.
In a possible embodiment, the battery module 200 further includes: a first inner panel 291, the first inner panel 291 being disposed between the first side wall 210 and the second side wall 220, and the first inner panel 291 being opposite to and spaced apart from the first side wall 210; one end of the heat conducting plate 230 penetrates through the first inner plate 291 and extends to be connected with the first side wall 210, the other end of the heat conducting plate 230 is connected with the second side wall 220, and two adjacent heat conducting plates 230, the first inner plate 291 and the second side wall 220 are enclosed to form a battery cell chamber.
Specifically, in the present embodiment, the case structure of the battery module 200 is divided into an inner layer structure and an outer layer structure. When the third side wall 250 and the fourth side wall 260 are not included, the first side wall 210, the second side wall 220, and the outermost two heat conductive plates 230 form an outer layer structure. When third side enclosure 250 and fourth side enclosure 260 are included, first side enclosure 210, second side enclosure 220, third side enclosure 250, and fourth side enclosure 260 together form an outer skin structure.
The first inner panel 291 between the first side wall 210 and the second side wall 220 forms an inner layer structure. The inner layer structure divides the inner space of the outer layer structure into a first heat dissipation air duct 201 and a module inner cavity 203. The first heat dissipation air duct 201 is located between the first inner plate 291 and the first side wall 210, and the module cavity 203 is located between the first inner plate 291 and the second side wall 220. The first heat dissipation air duct 201 is the heat dissipation air duct of the battery module 200, that is, the heat dissipation air duct is provided on one side of the battery cell 240.
In a possible embodiment, the battery module 200 further includes: a second inner plate 292, the second inner plate 292 being disposed between the first inner plate 291 and the second side wall 220, and the second inner plate 292 being opposite and spaced apart from both the first inner plate 291 and the second side wall 220; one end of the heat conductive plate 230 penetrates through the first inner plate 291 and extends to be connected with the first side wall 210, the other end of the heat conductive plate 230 penetrates through the second inner plate 292 and extends to be connected with the second side wall 220, and two adjacent heat conductive plates 230, the first inner plate 291 and the second inner plate 292 are enclosed to form a cell chamber.
Specifically, in the present embodiment, the case structure of the battery module 200 is divided into an inner layer structure and an outer layer structure. When the third side wall 250 and the fourth side wall 260 are not included, the first side wall 210, the second side wall 220, and the outermost two heat conductive plates 230 form an outer layer structure. The first inner panel 291 and the second inner panel 292 between the first side wall 210 and the second side wall 220 form an inner layer structure. The inner layer structure divides the inner space of the outer layer structure into a first heat dissipation air duct 201, a module inner cavity 203 and a second heat dissipation air duct 202. The first heat dissipation air duct 201 is located between the first inner plate 291 and the first side wall 210, the module cavity 203 is located between the first inner plate 291 and the second inner plate 292, and the second heat dissipation air duct 202 is located between the second inner plate 292 and the second side wall 220. The first heat dissipation air channel 201 and the second heat dissipation air channel 202 together form a heat dissipation air channel of the battery module 200, that is, the heat dissipation air channels are provided at both sides of the battery cell 240, so as to ensure that heat inside the battery cell 240 can be dissipated relatively uniformly, and ensure that the temperature difference inside the single battery cell 240 is not excessive.
And a plurality of fence openings which are sequentially arranged are reserved on the first inner plate 291 and the second inner plate 292, and the fence openings can be equidistantly arranged for the heat-conducting plate 230 to pass through so as to provide limit and fixed support for the heat-conducting plate 230. In this manner, the plurality of heat-conductive plates 230 divide the module cavity 203 into a plurality of cell chambers to provide spacing and fixed support for the cells 240.
As an embodiment, each of the first and second inner plates 291 and 292 may be constructed in a plate-shaped structure provided with a plurality of rectangular holes spaced apart in a length direction to reserve a space through which the heat conductive plate 230 passes. At this time, both side surfaces of the battery cell 240 are in contact with the first inner plate 291 and the second inner plate 292, respectively.
As another embodiment, the first and second inner plates 291 and 292 may be further constructed as a mesh plate structure having not only a plurality of through holes but also a plurality of rectangular holes spaced apart in a length direction to reserve a space through which the heat conductive plate 230 passes. At this time, the through holes on the mesh plate structure not only can realize the limit support of the battery cell 240, but also can provide more space for the battery cell 240 to contact with high-speed air flow in the heat dissipation air duct so as to further improve the heat dissipation efficiency.
It can be seen that, in the present embodiment, the heat conducting plate array formed by the plurality of heat conducting plates 230 not only provides limiting and fixing support for the battery cells 240, but also can be used as an internal rib structure between the inner layer structure and the outer layer structure, so that the battery module 200 without the outer case still has better structural strength.
In a possible embodiment, the opening of the heat dissipation air duct on the side close to the tab side of the battery cell 240 is configured as an air inlet, and the opening of the heat dissipation air duct on the side far from the tab side of the battery cell 240 is configured as an air outlet.
Specifically, the battery module 200 may be placed sideways or vertically, and the heat dissipation air channels of the battery module 200 in the corresponding battery heat dissipation system are arranged along the height direction of the machine body 10, or the heat dissipation air channels are arranged along the horizontal direction.
If the battery module 200 is placed vertically, the heat dissipation air duct of the battery module 200 in the battery heat dissipation system is arranged along the height direction of the machine body 10, at this time, the air inlet of the heat dissipation air duct of the battery module 200 is arranged near the tab side of the battery core 240, and the air outlet of the heat dissipation air duct is arranged below the battery core 240, so that the structure is more close to the rotating incoming flow direction of the propeller of the whole machine.
In a second aspect, referring to fig. 5, the present embodiment further provides an aircraft, the aircraft including: the battery module 200 is arranged in the machine body 10, and a heat dissipation air channel of the battery module 200 is communicated with the air cooling channel 12.
The specific structure of the battery module 200 refers to the above embodiments, and because the aircraft adopts all the technical solutions of all the embodiments, the aircraft has at least all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.
In a possible embodiment, the aircraft further comprises: the active cooling component 500, the active cooling component 500 is disposed in the machine body 10, the active cooling component 500 is communicated with the air cooling channel 12 and is located at an upstream side of the heat dissipation air channel, and the active cooling component 500 is used for providing a refrigerant for the heat dissipation air channel.
Specifically, the active cooling module 500 includes a refrigerant storage member and a refrigerant release member, and the refrigerant storage member may be configured as a cold gas cylinder storing a special refrigerant, and is fixedly mounted on the machine body 10. One end of the refrigerant releasing member is communicated with the refrigerant storing member, the other end is communicated with the air cooling channel 12 on the upstream side of the battery module 200, and the refrigerant releasing member has a first state of communicating the refrigerant storing member with the air cooling channel 12, a second state of blocking the refrigerant storing member with the air cooling channel 12, and is switchable between the first state and the second state. The specific refrigerant release member may be configured as a solenoid valve or the like.
It is easy to understand that the heat dissipation structure provided in this embodiment is an air-cooled heat dissipation structure, and when the aircraft is in a take-off or landing stage or hovering condition, the air flow speed entering the air cooling channel 12 in the machine body 10 is insufficient, so that the heat dissipation capability of the battery module 200 meets the requirement. At this time, the refrigerant releasing member is controlled to switch to the second state, so that the refrigerant enters the air cooling channel 12. The refrigerant not only can quickly reduce the temperature of high-speed air flow, but also can enter the heat dissipation air channel inside the battery module 200 under the drive of the high-speed air flow, so that the temperature generated by the battery module 200 is taken away, the air cooling heat dissipation capacity of the system is greatly improved, and the requirement of stable heat dissipation capacity under actual conditions is met.
It is apparent that the aircraft provided in this embodiment cancels the external box structure of the battery module 200, lightens the overall weight of the battery module 200, combines the special air duct design formed by the heat-conducting plate 230 and the side wall inside the battery module 200, reasonably utilizes the high-speed air flow generated by the rotation and the flight incoming flow of the propeller of the eVTOL aircraft in the flight process, combines the design of the active cooling assembly 500 to ensure that the air-cooled heat dissipation system of the battery can meet the heat dissipation requirement of the whole machine on the battery, and provides a technical scheme which has both heat dissipation capability and higher weight requirement of the aircraft.
The foregoing description is only of the preferred embodiments of the present application, and is not intended to limit the scope of the application, but rather is intended to cover any equivalents of the structures or equivalent processes disclosed herein or in the alternative, which may be employed directly or indirectly in other related arts.
