Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery packs, and in particular to a heat dissipation device for a new energy battery pack. Background Art

[0002] New energy battery packs are widely promoted and used because of their environmental protection, cleanliness and energy saving. Traditional battery packs generally install battery equipment in a box shell. When working, they will emit high temperatures. Due to the increase in temperature, it will have an adverse effect on the operation of the battery pack and the battery is prone to damage. Therefore, a heat dissipation device is installed on the side to accelerate the internal airflow to cool it down.

[0003] A dust shield will be installed at the external air inlet of the heat dissipation device to prevent larger particles and some dust from entering the box shell and affecting the battery pack. During the use of the heat dissipation device, a layer of dust similar to spider webs will gradually adhere to the dust shield, which will clog the mesh of the dust shield and affect the heat dissipation effect.

[0004] Some heat dissipation devices will have a brush on the internal cooling fan, which is used to rotate synchronously with the cooling fan to clean the mesh. This structure can only clean the inner wall of the dustproof plate, and the debris blocked in the mesh cannot be effectively cleaned. For this reason, we designed a new energy battery pack heat dissipation device. Summary of the invention

[0005] The present invention proposes a new energy battery pack heat dissipation device, which solves the problem that a layer of dust similar to a spider web will gradually adhere to the dustproof plate during use of the heat dissipation device, and the dust will clog the mesh of the dustproof plate, thereby affecting the heat dissipation effect.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A new energy battery pack heat dissipation device, comprising a battery box, wherein two groups of heat dissipation mounting shells are installed symmetrically on the left and right of the battery box, a mounting opening is opened in the middle of the heat dissipation mounting shell, a dustproof plate is installed in the mounting opening, and a plurality of evenly distributed ventilation holes are opened on the dustproof plate;

[0008] A heat dissipation mechanism and an anti-blocking mechanism are installed in the heat dissipation installation shell, the anti-blocking mechanism includes a reciprocating structure installed inside the heat dissipation installation shell, and the reciprocating structure is connected to the heat dissipation mechanism, a displacement component is installed on the reciprocating structure, a cleaning plate is movably provided on the displacement component, a plurality of anti-blocking rods distributed at equal intervals are provided on the side of the cleaning plate away from the heat dissipation mechanism, the anti-blocking rods are slidably plugged with the ventilation holes on the dustproof plate, and a shutter component is installed on the outside of the heat dissipation installation shell;

[0009] The longitudinal number of anti-blocking rods is the same as the longitudinal number of ventilation holes, and the transverse number is 1 / 7 of the transverse number of ventilation holes, that is, the length of the cleaning plate is 1 / 7 of the length of the dustproof plate. The cleaning plate can only block a small part of the ventilation holes, and the rest will not be blocked, which is convenient for airflow.

[0010] Furthermore, the heat dissipation mechanism includes two groups of motor mounting frames which are symmetrically arranged front and back in the heat dissipation mounting shell, a heat dissipation motor is installed on the side of the motor mounting frame away from the dustproof plate, a drive shaft is rotatably installed on the motor mounting frame through a bearing, the end of the drive shaft close to the heat dissipation motor is connected to the output shaft of the heat dissipation motor through a coupling, and a heat dissipation fan is also installed on the drive shaft.

[0011] Furthermore, the cooling fan is a bidirectional cooling fan, the airflow directions of the left and right groups of cooling fans are consistent, and the rotation directions of the two groups of cooling mechanisms change periodically, the external airflow enters from one side through the cooling fan and flows out from the other side, thereby dissipating the heat of the internal battery pack, and is connected to the cooling motors in the two groups of cooling mechanisms through a timer, which is used to periodically change their direction, that is, the original air inlet becomes an air outlet, and the air outlet is convenient for the air inlet, so that when the air holes on the surface of the dustproof plate are cleaned, the removed dust can be blown away.

[0012] Furthermore, the reciprocating structure includes two groups of reciprocating guide rods symmetrically arranged front and back inside the heat dissipation mounting shell, and the two groups of reciprocating guide rods are movably sleeved with reciprocating guide blocks and return springs in sequence. The reciprocating guide blocks are slidably connected to the reciprocating guide rods, and the head and tail ends of the return spring are respectively abutted against the inner wall of the heat dissipation mounting shell and the reciprocating guide blocks. A reciprocating plate is respectively installed on the two reciprocating guide blocks, and a contact biasing block is rotatably installed on the side of the reciprocating guide block away from the reciprocating plate, and the displacement assembly is installed between the two groups of reciprocating plates.

[0013] Furthermore, a driving rod is rotatably mounted inside the heat dissipation mounting shell through a bearing and a bracket, and impact rings are respectively fixed at both ends of the driving rod, and an impact portion is provided on the outer ring of the impact ring, and the impact portions on the two impact rings are respectively in sliding contact with two contact bias blocks;

[0014] The outer surface of the driving shaft away from the heat dissipation fan is provided with a worm part, and the driving rod is provided with two sets of worm gears, and the worm gears are connected to the worm part;

[0015] The connection between the worm wheel and the worm part can also reduce the rotation speed of the driving rod, so that the driving rod and the impact ring rotate slowly, and the cooling fan rotates in the positive direction, that is, the external airflow flows in from the left side and the internal airflow of the battery box flows out through the right side. The rotation of the cooling fan will rotate the driving rod through the worm part and the worm wheel, so that the impact part intermittently hits the contact block, and then the reciprocating plate moves back and forth left and right. The cleaning plate and multiple anti-blocking rods will continuously reciprocate the ventilation holes of the dustproof plate back and forth to prevent them from being blocked.

[0016] Furthermore, the upper half of the contact block near the impact part is designed to form an impact slope, and the lower half is designed to form an impact arc surface. The arc rate of the impact arc surface is consistent with the arc rate of the driving rod. When the impact part moves along the impact arc surface, it has a longer path and time.

[0017] When the impact part rotates forward with the impact ring and the driving rod, its contact inclined surface will contact the impact inclined surface and the impact plane, and push it to move away from the impact ring. At this time, the entire displacement assembly, the cleaning plate, and the anti-blocking rod will move accordingly. The anti-blocking rod will be inserted into the ventilation hole. After that, after the impact part is separated from the contact bias block, under the action of the return spring, the displacement assembly, the cleaning plate, and the anti-blocking rod will return to their original positions and wait for the next movement.

[0018] A lifting groove is provided on the reciprocating plate, and a lifting guide block is provided on the side of the contact bias block close to the reciprocating plate. The lifting guide block is slidably placed in the lifting groove, and a compression spring is abutted between the upper end of the lifting guide block and the top of the lifting groove. At this time, the contact bias block can be pressed without contacting the impact ring, and the impact part can push the contact bias block to move upward when rotating, thereby preventing the reciprocating structure from moving.

[0019] Furthermore, the displacement assembly includes a moving lead screw rotatably mounted between two reciprocating plates, a moving screw seat is provided on the side of the cleaning plate close to the moving lead screw, the moving screw seat is threadedly connected to the moving lead screw, a displacement motor is fixedly mounted on the side of one reciprocating plate, and the moving lead screw is driven by the output shaft of the displacement motor;

[0020] The rotation of the displacement motor can make the moving screw rotate, and then make the cleaning plate move forward and backward, and each time the cleaning plate moves a distance of 1 / 7 of the dustproof plate. The cleaning plates can move one by one and clean a part of the dustproof plate. The cleaning plate can only block a small part of the air permeable holes, and the rest will not be blocked, so as to facilitate the circulation of airflow;

[0021] A displacement guide rod is also arranged between the two reciprocating plates. The cleaning plate is slidably connected to the displacement guide rod through a sliding sleeve, which can guide the forward and backward movement of the cleaning plate and improve stability.

[0022] Furthermore, the louver assembly includes an outer shell body installed on the outside of the heat dissipation mounting shell, and a plurality of linearly distributed louvers are rotatably installed on the inner side of the outer shell body through an axle pin, and the front and rear ends of two adjacent louvers are movably connected head to tail through a continuous plate, and a brush is provided on the side of the louver close to the dustproof plate, and the brush is in sliding contact with the surface of the dustproof plate. The plurality of louvers are movably connected in sequence through the continuous plate, and when one of the louvers is deflected, the remaining louvers will also swing accordingly, thereby allowing the brush to clean the surface of the dustproof plate, and the overall length of the brush is relatively large, so it can clean a larger area.

[0023] Furthermore, two groups of driving swing plates are symmetrically arranged at the bottom of the lowermost louver, and a deflection rod is arranged on the side of the reciprocating plate close to the dustproof plate. The deflection rod slides through the dustproof plate and the battery box is placed outside it. The deflection rod can move with the reciprocating plate, and then can push the driving swing plate to deflect. At this time, multiple louvers can deflect along their shaft pins, so that the brush can clean the surface of the dustproof plate;

[0024] A return spring is connected below the driving swing plate, and the other end of the return spring is connected to the inner wall of the outer shell. The return spring makes the shutter have a tendency to deflect upward, and it can return to its original position again after being compressed and deflected.

[0025] Beneficial effects of the present invention:

[0026] 1. By symmetrically setting two sets of heat dissipation mechanisms on the left and right sides of the new energy battery pack, and the two heat dissipation mechanisms are respectively connected to two sets of anti-blocking mechanisms, the two heat dissipation mechanisms enable the airflow to dissipate heat for the battery pack, and cooperate with the anti-blocking mechanism, it can clean the air permeable holes on the dustproof plate to avoid blockage and affect the heat dissipation effect;

[0027] 2. At one end of the exhaust of the new energy battery pack, the reciprocating structure in the heat dissipation mechanism can enable the cleaning plate and the anti-blocking rod to clean the ventilation holes to prevent them from being blocked, and the cleaned dust can be blown away directly and will not be sucked into the battery box. The left and right heat dissipation mechanisms will regularly change the direction of the airflow, so that the ventilation holes on both sides can be cleaned periodically;

[0028] 3. By setting a displacement component in the anti-blocking mechanism, the distance that the cleaning plate moves each time is a part of the dustproof plate. The cleaning plate can move one by one and clean a part of the dustproof plate. The cleaning plate can only block a small part of the air permeable holes, and the rest will not be blocked, which is convenient for the circulation of airflow;

[0029] 4. By setting a louver assembly on the outside of the dustproof plate, and connecting the louver assembly with the reciprocating structure, the reciprocating structure can make the multiple louvers in the louver assembly deflect up and down during the movement, so as to clean the dust attached to the surface of the dustproof plate. In conjunction with the cooling fan, the cleaned dust can be blown away to prevent dust from being inhaled into the battery box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Reference Figure 1-Figure 11 A new energy battery pack heat dissipation device comprises a battery box 1, wherein the battery box 1 is symmetrically provided with two sets of heat dissipation mounting shells 2, a mounting opening is provided in the middle of the heat dissipation mounting shells 2, a dustproof plate 3 is provided in the mounting opening, and a plurality of evenly distributed ventilation holes 31 are provided on the dustproof plate 3;

[0044] A heat dissipation mechanism 4 and an anti-blocking mechanism 5 are installed in the heat dissipation installation shell 2. The anti-blocking mechanism 5 includes a reciprocating structure 53 installed inside the heat dissipation installation shell 2, and the reciprocating structure 53 is connected to the heat dissipation mechanism 4. A displacement component 52 is installed on the reciprocating structure 53. A cleaning plate 51 is movably provided on the displacement component 52. A plurality of anti-blocking rods 54 distributed at equal intervals are provided on the side of the cleaning plate 51 away from the heat dissipation mechanism 4. The anti-blocking rods 54 are slidably plugged with the ventilation holes 31 on the dustproof plate 3. A shutter component 6 is installed on the outside of the heat dissipation installation shell 2.

[0045] The longitudinal number of the anti-blocking rods 54 is the same as the longitudinal number of the ventilation holes 31, and the transverse number thereof is 1 / 7 of the transverse number of the ventilation holes 31, that is, the length of the cleaning plate 51 is 1 / 7 of the length of the dustproof plate 3. The cleaning plate 51 can only block a small part of the ventilation holes 31, and the rest will not be blocked, thereby facilitating the circulation of airflow.

[0046] The heat dissipation mechanism 4 includes two groups of motor mounting frames 42 which are symmetrically arranged in the heat dissipation mounting shell 2. A heat dissipation motor 41 is installed on the side of the motor mounting frame 42 away from the dustproof plate 3. A drive shaft 44 is rotatably installed on the motor mounting frame 42 through a bearing. The end of the drive shaft 44 close to the heat dissipation motor 41 is connected to the output shaft of the heat dissipation motor 41 through a coupling. The drive shaft 44 is also equipped with a heat dissipation fan 43.

[0047] The cooling fan 43 is a bidirectional cooling fan 43, the airflow directions of the left and right cooling fans 43 are consistent, and the rotation directions of the two cooling mechanisms 4 are changed regularly;

[0048] The external air flow enters from one side through the heat dissipation fan 43 and flows out from the other side, thereby dissipating the heat of the internal battery pack, and is connected to the heat dissipation motors 41 in the two sets of heat dissipation mechanisms 4 through a timer, which is used to regularly change their direction, that is, the original air inlet is changed into an air outlet, and the air outlet is convenient for the air inlet, so that when the air permeable holes 31 on the surface of the dustproof plate 3 are cleaned, the removed dust can be blown away.

[0049] The reciprocating structure 53 includes two groups of reciprocating guide rods 531 symmetrically arranged front and back inside the heat dissipation mounting shell 2, and the two groups of reciprocating guide rods 531 are movably sleeved with reciprocating guide blocks 534 and return springs 532 in sequence. The reciprocating guide blocks 534 are slidably connected to the reciprocating guide rods 531, and the head and tail ends of the return spring 532 are respectively abutted against the inner wall of the heat dissipation mounting shell 2 and the reciprocating guide blocks 534. A reciprocating plate 533 is respectively installed on the two reciprocating guide blocks 534, and a contact biasing block 538 is rotatably installed on the side of the reciprocating guide block 534 away from the reciprocating plate 533. The displacement assembly 52 is installed between the two groups of reciprocating plates 533.

[0050] A driving rod 535 is rotatably mounted inside the heat dissipation mounting shell 2 through a bearing and a bracket, and impact rings 537 are fixed at both ends of the driving rod 535. The outer ring of the impact ring 537 is provided with an impact portion 5371. The impact portions 5371 on the two impact rings 537 are in sliding contact with the two contact biasing blocks 538 respectively.

[0051] A worm portion 45 is disposed on the outer surface of the driving shaft 44 away from the heat dissipation fan 43, and two sets of worm gears 536 are disposed on the driving rod 535, and the worm gears 536 are connected to the worm portion 45;

[0052] The connection between the worm wheel 536 and the worm part 45 can also reduce the rotation speed of the driving rod 535, so that the driving rod 535 and the impact ring 537 rotate slowly, and the cooling fan 43 rotates in the forward direction, that is, the external airflow flows in from the left side and the internal airflow of the battery box 1 flows out through the right side. The rotation of the cooling fan 43 will rotate the driving rod 535 through the worm part 45 and the worm wheel 536, so that the impact part 5371 intermittently impacts the contact bias block 538, so that the reciprocating plate 533 moves back and forth, and the cleaning plate 51 and multiple anti-blocking rods 54 will continuously reciprocate the air permeable holes 31 of the dustproof plate 3 to prevent them from being blocked.

[0053] The upper half of the contact block 538 near the impact portion 5371 is designed to form an impact slope 5381, and the lower half of the contact block 538 is designed to form an impact arc surface 5382. The arc rate of the impact arc surface 5382 is consistent with the arc rate of the driving rod 535. When the impact portion 5371 moves along the impact arc surface 5382, it has a longer path and time.

[0054] When the impact part 5371 rotates forwardly with the impact ring 537 and the driving rod 535, the impact ring 537 will contact the impact inclined surface 5381 and the impact arc surface 5382, and push it to move away from the impact ring 537. At this time, the entire displacement assembly 52, the cleaning plate 51, and the anti-blocking rod 54 will move accordingly, and the anti-blocking rod 54 will be inserted into the ventilation hole 31. After that, after the impact part 5371 is separated from the contact bias block 538, under the action of the return spring 532, the displacement assembly 52, the cleaning plate 51, and the anti-blocking rod 54 will return to their original positions and wait for the next movement.

[0055] A lifting groove 5331 is provided on the reciprocating plate 533, and a lifting guide block 5383 is provided on the side of the contact bias block 538 close to the reciprocating plate 533. The lifting guide block 5383 is slidably placed in the lifting groove 5331, and a compression spring is abutted between the upper end of the lifting guide block 5383 and the top of the lifting groove 5331. The compression spring makes the lifting guide block 5383 tend to move downward. When the impact ring 537 rotates in the opposite direction, the contact bias block 538 will not contact the impact ring 537 at this time. The impact part 5371 can push the contact bias block 538 to move upward when rotating, thereby preventing the reciprocating structure 53 from moving.

[0056] The displacement assembly 52 includes a moving screw 522 rotatably installed between two reciprocating plates 533. A moving screw seat 523 is provided on the side of the cleaning plate 51 close to the moving screw 522. The moving screw seat 523 is threadedly connected to the moving screw 522. A displacement motor 521 is fixedly installed on the side of a reciprocating plate 533. The moving screw 522 is driven by the output shaft of the displacement motor 521.

[0057] The rotation of the displacement motor 521 can rotate the moving screw 522, thereby moving the cleaning plate 51 forward and backward, and each time the cleaning plate 51 moves a distance of 1 / 7 of the dustproof plate 3, the cleaning plate 51 can move one by one, and clean a part of the dustproof plate 3, the cleaning plate 51 can only block a small part of the air permeable hole 31, and the rest will not be blocked, so as to facilitate the circulation of airflow;

[0058] A displacement guide rod 524 is also provided between the two reciprocating plates 533 , and the cleaning plate 51 is slidably connected to the displacement guide rod 524 via a sliding sleeve, which can guide the forward and backward movement of the cleaning plate 51 and improve stability.

[0059] The louver assembly 6 includes an outer shell body 66 installed on the outside of the heat dissipation mounting shell 2, and a plurality of linearly distributed louvers 61 are rotatably installed on the inner side of the outer shell body 66 through an axle pin. The front and rear ends of two adjacent louvers 61 are movably connected through a continuous plate 62. A brush 63 is provided on the side of the louver 61 close to the dustproof plate 3, and the brush 63 is in sliding contact with the surface of the dustproof plate 3. The plurality of louvers 61 are movably connected in sequence through the continuous plate 62. When one of the louvers 61 is deflected, the continuous plate 62 will drive the plurality of louvers 61 to swing accordingly, thereby causing the brush 63 to clean the surface of the dustproof plate 3. The overall length of the brush 63 is relatively large, so it can clean a larger area.

[0060] Two groups of driving swing plates 64 are symmetrically arranged at the bottom of the bottom louver 61. A deflection rod 539 is arranged on the side of the reciprocating plate 533 close to the dustproof plate 3. The deflection rod 539 slides through the dustproof plate 3 and the battery box 1 is placed outside it. The deflection rod 539 contacts the driving swing plate 64. The deflection rod 539 can move with the reciprocating plate 533. The deflection rod 539 moving outward pushes the driving swing plate 64 to rotate with the shaft pin of the bottom louver 61 as the axis. The bottom louver 61 will deflect accordingly. At this time, multiple louvers 61 can deflect along their shaft pins, so that the brush 63 cleans the surface of the dustproof plate 3.

[0061] A return spring 65 is connected below the driving swing plate 64 , and the other end of the return spring 65 is connected to the inner wall of the outer shell 66 .

[0062] Working principle: When the new energy battery pack is in use, the heat dissipation motors 41 in the front and rear heat dissipation mechanisms 4 will be turned on. At this time, the external airflow enters through the left side of the heat dissipation fan 43 and flows out from the right side, thereby dissipating the heat of the internal battery pack. At this time, the heat dissipation fan 43 on the right side rotates forward, and the heat dissipation fan 43 on the left side rotates reversely;

[0063] Since the driving shaft 44 of the heat dissipation mechanism 4 is connected to the worm gear 536 on the driving rod 535 through the worm gear portion 45, the driving shaft 44 will drive the driving rod 535 to rotate together under the action of the heat dissipation motor 41, so that the impact portion 5371 will intermittently impact the contact block 538, and the impact portion 5371 will contact the impact inclined surface 5381 and the impact arc surface 5382, and push it to move toward the side away from the impact ring 537. At this time, the entire displacement assembly 52, the cleaning plate 51, and the anti-blocking rod 54 will move accordingly, and the anti-blocking rod 54 will be inserted into the ventilation hole 31. After that, after the impact portion 5371 is separated from the contact biased block 538, under the action of the return spring 532, the displacement assembly 52, the cleaning plate 51, and the anti-blocking rod 54 will return to their original positions and wait for the next movement. At this time, the airflow flows from left to right, and the anti-blocking rod 54 on the right cleans the ventilation hole 31 on the right, while the anti-blocking rod 54 on the left will not move, and the cleaned dust will be directly blown away;

[0064] We reasonably set the transmission ratio between the worm part 45 and the worm wheel 536, thereby reducing the rotation speed of the driving rod 535, so that the reciprocating time of the cleaning plate 51 is extended;

[0065] The anti-blocking rod 54 on the cleaning plate 51 is inserted into the air hole 31 in the dustproof plate 3, and then after being separated from the air hole 31, the impact part 5371 is now separated from the contact bias block 538 and a certain gap is left. Each time the anti-blocking rod 54 is separated from the air hole 31, the displacement motor 521 is started and moved a unit distance to evenly divide the air hole 31 on the dustproof plate 3 into several parts. The cleaning plate 51 cleans one part each time, and then moves at the evenly divided distance, and then waits for the next reciprocating movement and cleaning, and repeats the above operation until it moves to the farthest point, and then the displacement motor 521 rotates in the opposite direction again and returns to the original path;

[0066] After a period of time, the direction of the heat dissipation fan 43 is changed, that is, the external airflow enters through the right side of the heat dissipation fan 43 and flows out from the left side. At this time, the heat dissipation fan 43 on the left side rotates forward, and the heat dissipation fan 43 on the right side rotates reversely. When the heat dissipation fan 43 rotates reversely, the impact part 5371 rotates counterclockwise. When the impact part 5371 rotates, it can push the contact bias block 538 to move upward. At this time, the entire contact bias block 538 moves upward until the two are out of contact. In this process, the entire displacement assembly 52 and the cleaning plate 51 and the anti-blocking rod 54 will not move accordingly. At this time, the airflow flows from right to left, and the anti-blocking rod 54 on the left side cleans the ventilation holes 31 on the left side, while the anti-blocking rod 54 on the right side does not move, and the cleaned dust will be directly blown away.

[0067] When the reciprocating plate 533 is moving, the deflection rod 539 can move with the reciprocating plate 533, and then can push the driving swing plate 64 to deflect. Since multiple louvers 61 are movably connected in sequence through the continuous plate 62, when one of the louvers 61 is deflected, the other louvers 61 will also swing accordingly, so that the brush 63 can clean the surface of the dustproof plate 3. The overall length of the brush 63 is relatively large, so it can clean a larger area, so that dust will not accumulate on the surface of the dustproof plate 3, and it can clean the dust attached to the surface of the anti-blocking rod 54.

[0068] By symmetrically arranging two groups of heat dissipation mechanisms 4 on the left and right sides of the new energy battery pack, and the two heat dissipation mechanisms 4 are respectively connected to the two groups of anti-blocking mechanisms 5, the two heat dissipation mechanisms 4 enable the airflow to dissipate heat to the battery pack, and the anti-blocking mechanisms 5 are arranged in cooperation, which can clean the air permeable holes 31 on the dustproof plate 3 to prevent them from being blocked and affecting the heat dissipation effect;

[0069] At one end of the exhaust of the new energy battery pack, the reciprocating structure 53 in the heat dissipation mechanism 4 enables the cleaning plate 51 and the anti-blocking rod 54 to clean the ventilation holes 31 to prevent them from being blocked, and the cleaned dust can be blown away directly and will not be sucked into the battery box 1. The left and right heat dissipation mechanisms 4 regularly change the direction of the airflow, so that the ventilation holes 31 on both sides can be cleaned periodically;

[0070] By setting a displacement component 52 in the anti-blocking mechanism 5, the distance that the cleaning plate 51 moves each time is a part of the dustproof plate 3, and the cleaning plate 51 can move one by one and clean a part of the dustproof plate 3. The cleaning plate 51 can only block a small part of the air permeable hole 31, and the rest will not be blocked, so as to facilitate the circulation of airflow;
