Description

Technical Field

[0001] This invention relates to the technical field of heat exchange equipment, and more specifically, to a top-mounted heat exchange device, its control method, and its transport equipment. Background Technology

[0002] In the existing technology, parking air conditioners are a type of heat exchange equipment. Generally speaking, parking air conditioners are mostly integrated units, but in order to pursue higher performance indicators, they can be designed as split units.

[0003] Currently, there are two installation methods for split-type air conditioners: backpack-style and roof-mounted. Backpack-style air conditioners are installed on the back of the driver's cabin. Their structure has minimal impact on starting performance, and performance indicators are not significantly different when the car is in motion or parked. However, with roof-mounted air conditioners, due to the need for air intake space, an axial flow fan system is required to achieve higher performance. Axial flow fans generally have axial air intake and axial air output, specifically bottom intake and top exhaust. This structure performs well when parked, but when the car is in motion and the parking air conditioner is on, it faces a significant oncoming wind speed. In this situation, the roof-mounted parking air conditioner divides the airflow over the roof into two parts: the intake area, being relatively small, experiences less boundary layer separation, while the top experiences greater boundary layer separation. This results in lower pressure at the intake and a pressure difference at the exhaust, creating a reverse pressure differential.

[0004] As can be seen from the above, the performance of existing top-mounted heat exchange equipment is affected by wind speed during use, resulting in poor performance. Summary of the Invention

[0005] The main objective of this invention is to provide a top-mounted heat exchanger, its control method, and a transport device to solve the problem that the performance of existing top-mounted heat exchangers is poor due to the influence of wind speed during use.

[0006] To achieve the above objectives, according to one aspect of the present invention, a top-mounted heat exchanger is provided. The top-mounted heat exchanger includes a housing and a flow guiding assembly. The housing has a flow passage and an air inlet located downstream of the flow passage and communicating with the flow passage. The flow guiding assembly is installed inside the housing and includes a plurality of baffles disposed at the air inlet. The baffles have at least a first position extending into the flow passage and a second position exiting the flow passage, and some of the baffles operate asynchronously.

[0007] Furthermore, the flow channel extends along a first direction, and multiple baffles are sequentially arranged along a second direction perpendicular to the first direction; and / or the baffles have an arched arc-shaped flow-guiding surface, and when the baffle is in the first position, the side of the baffle facing the air inlet end of the flow channel is an arc-shaped flow-guiding surface.

[0008] Furthermore, the drainage assembly also includes a drive member; a connecting rod extending along a second direction perpendicular to the first direction, multiple baffles mounted on the connecting rod, and the drive member drivingly cooperating with the multiple baffles through the connecting rod, the drive member providing driving force for the baffles to switch between a first position and a second position.

[0009] Furthermore, the first end of the baffle is fixedly mounted on the connecting rod, and the second end of the baffle swings circumferentially along the connecting rod to extend into or exit the flow channel.

[0010] Furthermore, the drainage assembly also includes a force-applying structure, which is disposed on the connecting rod. The force-applying structure includes a plurality of force-applying parts spaced apart circumferentially along the connecting rod, and at least two of the plurality of force-applying parts are spaced apart axially along the connecting rod so that at least two force-applying parts correspond to different baffles; and a force-receiving structure, which is disposed on the baffles, and the force-applying parts are used to apply force to the corresponding force-receiving structure to change the position of the corresponding baffle.

[0011] Furthermore, multiple force-applying parts form at least two force-applying groups, each force-applying group includes at least one force-applying part, the force-applying parts of each force-applying group are arranged coaxially along the connecting rod, and the force-applying parts of two adjacent force-applying groups are spaced apart along the circumferential direction of the connecting rod.

[0012] Furthermore, the force-applying part is a snap-fit ​​arch, and the first end of the force-applying part is rotatably mounted on the connecting rod; the force-receiving structure is a groove structure, and the second end of the force-applying part and the groove structure are spaced apart along the circumference of the connecting rod, or the two ends of the force-applying part are at an angle to the connecting rod, and at least a portion of the two ends of the force-applying part extends into the interior of the groove structure.

[0013] Furthermore, the drainage assembly also includes a reset member disposed between the force-applying part and the connecting rod, which provides a driving force for the second end of the force-applying part to rotate toward the interior of the groove structure.

[0014] Furthermore, the outer surface of the connecting rod has a circumferentially extending receiving groove, the connection end of the reset member and the connecting rod is located inside the receiving groove, the force-applying part is received inside the receiving groove or the second end of the force-applying part rotates away from the connecting rod and extends out of the receiving groove.

[0015] Furthermore, when the force-applying part is housed inside the receiving groove, the surface of the force-applying part facing the bottom of the receiving groove is in contact with the bottom surface of the receiving groove.

[0016] Furthermore, the top-mounted heat exchanger also includes a wind speed sensor mounted on the housing; and a controller located inside the housing, which is signal-connected to the wind speed sensor and the drive unit of the air intake assembly.

[0017] According to another aspect of the present invention, a transport device is provided, the transport device including a mobile body and the above-mentioned top-mounted heat exchange device, the housing of the top-mounted heat exchange device is mounted on the outer surface of the mobile body, the flow passage of the housing is formed at one end of the housing facing the mobile body, and the air inlet of the housing is disposed facing the mobile body.

[0018] According to another aspect of the present invention, a control method for a top-mounted heat exchanger is provided. The top-mounted heat exchanger is the aforementioned top-mounted heat exchanger. The control method for the top-mounted heat exchanger includes acquiring real-time wind speed; determining the operating state of the top-mounted heat exchanger based on the relationship between the real-time wind speed and a preset wind speed range; and controlling the rotation angle of the connecting rod of the flow-inducing assembly of the top-mounted heat exchanger based on the operating state of the top-mounted heat exchanger.

[0019] Furthermore, the control method for the top-mounted heat exchanger also includes dividing the preset wind speed range into N levels, with each level corresponding to one of the N operating states of the top-mounted heat exchanger. When the top-mounted heat exchanger performs different operating states, the connecting rod rotates at different angles.

[0020] Furthermore, the preset wind speed range is divided into three levels: the first level is set to wind speed less than 5 meters per second; the second level is set to wind speed greater than or equal to 5 meters per second and less than or equal to 10 meters per second; and the third level is set to wind speed greater than 10 meters per second.

[0021] Furthermore, when the real-time wind speed is within the first wind speed range, the connecting rod rotates by a first angle, and the connecting rod drives the first baffle to rotate through the first force application group set on the connecting rod; when the real-time wind speed is within the second wind speed range, the connecting rod rotates by a second angle, and the connecting rod drives the first baffle and the second baffle to rotate through the first force application group and the second force application group set on the connecting rod; when the real-time wind speed is within the third wind speed range, the connecting rod rotates by a third angle, and the connecting rod drives the first baffle, the second baffle, and the third baffle to rotate through the first force application group, the second force application group, and the third force application group set on the connecting rod.

[0022] Furthermore, the first angle is set to satisfy angle = 0.5031 × V 2 +11.051×V; Set the second angle to satisfy angle=0.7731×V 2 +1.4277×V; Set the third angle to satisfy angle=0.311×V 2 +1.8558×V, where V is the real-time wind speed.

[0023] According to the technical solution of the present invention, the top-mounted heat exchanger includes a shell and a flow guiding assembly. The shell has a flow channel and an air inlet located downstream of the flow channel and communicating with the flow channel. The flow guiding assembly is installed inside the shell and includes multiple baffles. The multiple baffles are disposed at the air inlet. The baffles have a first position where at least a portion extends into the flow channel and a second position where at least a portion exits the flow channel, and some of the multiple baffles operate asynchronously.

[0024] As can be seen from the above, by installing multiple asynchronously operating baffles at the air inlet connected to the flow channel, different numbers of baffles are switched from the second position to the first position when different air velocities flow through the flow channel. This allows the airflow inside the flow channel to be guided by the baffles and enter the interior of the shell through the air inlet. Specifically, when the gas velocity inside the flow channel gradually increases, the baffles can effectively replenish the air inside the shell, avoiding the performance problems caused by insufficient airflow in top-mounted heat exchangers.

[0037] Example 1

[0038] To address the issue of poor performance caused by wind speed in existing top-mounted heat exchangers, this invention provides a top-mounted heat exchanger that is installed on the top of a mobile body 30.

[0039] like Figures 1 to 5 As shown, the top-mounted heat exchanger includes a housing 10 and a flow diversion assembly 20. The housing 10 has a flow passage 110 and an air inlet 120 located downstream of the flow passage 110 and communicating with the flow passage 110. The flow diversion assembly 20 is installed inside the housing 10 and includes multiple baffles 210. The multiple baffles 210 are disposed at the air inlet 120. The baffles 210 have at least a first position extending into the flow passage 110 and a second position exiting the flow passage 110, and some of the multiple baffles 210 operate asynchronously.

[0040] Specifically, multiple baffles 210 with asynchronous operation are installed at the air inlet 120 connected to the flow channel 110. This allows for the flow to be guided by the baffles 210 when different wind speeds flow through the flow channel 110. By switching different numbers of baffles 210 from the second position to the first position, the airflow inside the flow channel 110 is guided by the baffles 210 and enters the interior of the housing 10 through the air inlet 120.

[0041] When the gas velocity inside the flow channel 110 gradually increases, the baffle 210 can guide the flow to achieve the technical effect of replenishing the gas inside the shell 10, thus avoiding the problem of poor performance of the top-mounted heat exchanger due to small airflow.

[0042] Furthermore, the flow passage 110 extends along the first direction and flows through the opening formed between the movable body 30 and the housing 10. The air inlet 120 of the housing 10 is arranged facing the top of the movable body 30, that is, the opening direction of the air inlet 120 is arranged along the height direction of the housing 10. The opening direction of the air inlet 120 is perpendicular to the first direction. After the airflow outside the housing 10 flows into the interior of the flow passage 110, some of the gas enters the interior of the housing 10 through the air inlet 120.

[0043] It should be noted that the downstream of the flow channel 110 is along the gas flow direction inside the flow channel 110. The gas first enters the interior of the flow channel 110 before entering the air inlet 120. The first direction is the X direction shown in the figure, the second direction is the Y direction shown in the figure, and the height direction of the housing 10 is the Z direction shown in the figure.

[0044] Furthermore, multiple baffles 210 are sequentially arranged along a second direction perpendicular to the first direction, so that after the baffles 210 are switched from the second position to the first position, the gas inside the flow channel 110 can flow to the baffles 210, and when the multiple baffles 210 are in the first position, the incoming air can contact the multiple baffles 210 and flow along the baffles 210 toward the air inlet 120.

[0045] In this embodiment, the baffle 210 has an arched arc-shaped flow-guiding surface 211. When the baffle 210 is in the first position, the side of the baffle 210 facing the air inlet end of the flow channel 110 is the arched arc-shaped flow-guiding surface 211. When the baffle 210 is in the first position, the arched arc-shaped flow-guiding surface 211 of the baffle 210 serves as the windward surface, so that after the gas flowing into the interior of the flow channel 110 comes into contact with the arc-shaped flow-guiding surface 211, it flows along the arc-shaped flow-guiding surface 211 under the guidance of the arc-shaped flow-guiding surface 211. The arc-shaped flow-guiding surface 211 is used to guide the gas inside the flow channel 110 towards the air inlet 120.

[0046] like Figures 1 to 5 As shown, the drainage assembly 20 also includes a drive member and a connecting rod 220. The connecting rod 220 extends along a second direction perpendicular to the first direction. Multiple baffles 210 are mounted on the connecting rod 220. The drive member drives and cooperates with the multiple baffles 210 through the connecting rod 220. The drive member provides driving force for the baffles 210 to switch between a first position and a second position.

[0047] Specifically, the driving component drives the connecting rod 220 to rotate, and the connecting rod 220 drives the baffle 210 to rotate. When the connecting rod 220 rotates at different angles, the corresponding connecting rod 220 drives different baffles 210 to rotate, so that multiple baffles 210 rotate asynchronously.

[0048] Furthermore, the driving component is a motor, and the forward and reverse rotation of the motor realizes the clockwise and counterclockwise rotation of the control link 220. The rotation of the link 220 in turn drives the baffle 210 to swing, so as to achieve the switching of the baffle 210 between the first position and the second position.

[0049] Furthermore, the first end of the baffle 210 is fixedly mounted on the connecting rod 220, and the second end of the baffle 210 swings circumferentially along the connecting rod 220 to extend into or exit the flow channel 110.

[0050] The connecting rod 220 rotates, causing the first end of the baffle 210 to rotate, so that the second end of the baffle 210 swings accordingly. When the baffle 210 is in the first position, the second end of the baffle 210 extends into the interior of the flow channel 110; when the baffle 210 is in the second position, the second end of the baffle 210 exits the flow channel 110.

[0051] like Figures 1 to 5 As shown, the drainage assembly 20 also includes a force-applying structure and a force-receiving structure. The force-applying structure is disposed on the connecting rod 220 and includes a plurality of force-applying parts 230 spaced apart circumferentially along the connecting rod 220. At least two of the plurality of force-applying parts 230 are spaced apart axially along the connecting rod 220 so that at least two force-applying parts 230 correspond to different baffles 210. The force-receiving structure is disposed on the baffles 210. The force-applying parts 230 are used to apply force to the corresponding force-receiving structure to change the position of the corresponding baffles 210.

[0052] Specifically, when the force-applying part 230 and the force-receiving structure are aligned, the connecting rod 220 and the baffle 210 are fixedly connected through the force-applying part 230 and the force-receiving structure, and the rotation of the connecting rod 220 drives the baffle 210 to switch positions.

[0053] Furthermore, multiple force-applying parts 230 correspond to multiple baffles 210. The force-applying parts 230 and baffles 210 can be arranged in a one-to-one correspondence, or multiple force-applying parts 230 can correspond to one baffle 210, or one force-applying part 230 can correspond to multiple baffles 210. When multiple force-applying parts 230 correspond to one baffle 210, the multiple force-applying parts 230 are collinear along the axial direction of the connecting rod 220.

[0054] Furthermore, the multiple force-applying parts 230 form at least two force-applying groups, each force-applying group including at least one force-applying part 230, the force-applying parts 230 of each force-applying group are arranged co-linearly along the axial direction of the connecting rod 220, and the force-applying parts 230 of two adjacent force-applying groups are arranged at intervals along the circumferential direction of the connecting rod 220.

[0055] Each force application group may include one baffle 210 or multiple baffles 210. The multiple baffles 210 may be arranged adjacently or spaced apart.

[0056] In this embodiment, the force-applying parts 230 of two adjacent force-applying groups are arranged at circumferential intervals along the connecting rod 220, thereby driving different force-applying groups to rotate at different angles of rotation of the connecting rod 220, so as to drive the corresponding baffles 210 to rotate, and thus achieving different air volume by realizing different numbers of baffles 210.

[0057] like Figures 1 to 5 As shown, the force-applying part 230 is a snap-fit ​​arch, and the first end of the force-applying part 230 is rotatably mounted on the connecting rod 220. The force-bearing structure is a groove structure. The second end of the force-applying part 230 and the groove structure are spaced apart along the circumference of the connecting rod 220, or the two ends of the force-applying part 230 are at an angle to the connecting rod 220. At least a portion of the two ends of the force-applying part 230 extends into the interior of the groove structure.

[0058] Specifically, when the connecting rod 220 rotates in the first direction, the angle between the second end of the force-applying part 230 and the connecting rod 220 gradually increases, and the second end of the force-applying part 230 switches from being spaced apart from the groove structure to extending into the interior of the groove structure in at least a portion. After at least a portion of the force-applying part 230 extends into the interior of the groove structure, the force-applying part 230 is driven to connect with the baffle 210 to achieve synchronous rotation of the force-applying part 230 and the baffle 210.

[0059] Furthermore, when the connecting rod 220 rotates in the second direction, the angle between the second end of the force-applying part 230 and the connecting rod 220 gradually decreases, and the second end of the force-applying part 230 switches from extending a small portion into the interior of the groove structure to being spaced apart from the groove structure.

[0060] It should be noted that the first direction and the second direction are either clockwise or counterclockwise.

[0061] Furthermore, the drainage assembly 20 also includes a reset member disposed between the force-applying part 230 and the connecting rod 220. The reset member provides a driving force for the second end of the force-applying part 230 to rotate toward the interior of the groove structure. Under the driving action of the reset member, the second end of the force-applying part 230 moves in the direction of increasing angle with the connecting rod 220, thereby enabling at least a portion of the second end of the force-applying part 230 to extend into the interior of the groove structure.

[0062] Furthermore, the outer surface of the connecting rod 220 has a circumferentially extending receiving groove, the connection end of the reset member and the connecting rod 220 is located inside the receiving groove, the force-applying part 230 is accommodated inside the receiving groove or the second end of the force-applying part 230 rotates away from the connecting rod 220 and extends out of the receiving groove.

[0063] It should be noted that the reset member is a spring. When the force-applying part 230 is inside the receiving groove, the reset member is compressed, and the spring provides elastic force to the second end of the force-applying part 230 as it rotates out of the receiving groove.

[0064] In this embodiment, the baffle 210 has an installation channel structure 212 extending along a second direction. The connecting rod 220 passes through the installation channel structure 212. The force-applying part 230 is disposed on the outer peripheral surface of the connecting rod 220, and the force-bearing structure is disposed on the inner wall surface of the installation channel structure 212. The inner wall surface of the installation channel structure 212 has a clearance groove disposed circumferentially along the connecting rod 220, so that when the clearance groove is aligned with the force-applying part 230, the force-applying part 230 can rotate under the drive of the reset member to be angled to the connecting rod 220. When other areas on the inner wall surface of the installation channel abut against the force-applying part 230, the force-applying part 230 can be pressed toward the connecting rod 220. The clearance groove can be connected to the groove structure or it can be part of the groove structure.

[0065] Furthermore, when the force-applying part 230 is housed inside the receiving groove, the surface of the force-applying part 230 facing the bottom of the receiving groove is in contact with the bottom surface of the receiving groove.

[0066] In this embodiment, the top-mounted heat exchanger also includes a wind speed sensor and a controller. The wind speed sensor is mounted on the housing 10, and the controller is located inside the housing 10. The controller is signal-connected to the wind speed sensor and the drive unit of the airflow diversion assembly 20. The wind speed sensor is used to acquire real-time wind speed and send the collected electrical signal to the controller. The controller determines the wind speed range to drive the corresponding baffles 210.

[0067] Example 2

[0068] This invention provides a transport device, which includes a mobile body 30 and a top-mounted heat exchanger as described in Embodiment 1. The housing 10 of the top-mounted heat exchanger is mounted on the outer surface of the mobile body 30. A flow channel 110 of the housing 10 is formed at one end of the housing 10 facing the mobile body 30, and an air inlet 120 of the housing 10 is disposed facing the mobile body 30. Specifically, the air inlet 120 is located on the side of the flow channel 110 away from the mobile body 30.

[0069] In this embodiment, the mobile body 30 may be a vehicle.

[0070] Example 3

[0071] This invention provides a control method for a top-mounted heat exchanger, which is the heat exchanger in Embodiment 1.

[0072] like Figure 6 As shown, the control method for the top-mounted heat exchanger includes:

[0073] Get real-time wind speed;

[0074] The working status of the top-mounted heat exchanger is determined by the relationship between the real-time wind speed and the preset wind speed range.

[0075] The rotation angle of the connecting rod 220 of the diversion assembly 20 of the top-mounted heat exchanger is controlled according to the working status of the top-mounted heat exchanger.

[0076] The system obtains the real-time wind speed through a wind speed sensor, and based on the relationship between the real-time wind speed and the preset wind speed range, the controller controls the linkage 220 to rotate through the drive component, thereby controlling the working status of the top-mounted heat exchanger.

[0077] Furthermore, the control method for the top-mounted heat exchanger also includes dividing the preset wind speed range into N levels, with each level corresponding to one of the N operating states of the top-mounted heat exchanger. When the top-mounted heat exchanger performs different operating states, the connecting rod 220 rotates at different angles. Each operating state of the top-mounted heat exchanger corresponds to a preset angle of the connecting rod 220.

[0078] In this embodiment, the preset wind speed range is divided into three levels: the first level is set to a wind speed less than 5 meters per second; the second level is set to a wind speed greater than or equal to 5 meters per second and less than or equal to 10 meters per second; and the third level is set to a wind speed greater than 10 meters per second. Based on the wind speed range to which the real-time wind speed belongs, the corresponding working state is executed, namely, the preset angle of rotation of the linkage 220 is achieved.

[0079] Furthermore, when the real-time wind speed is within the range of the first wind speed, the connecting rod 220 rotates by a first angle, and the connecting rod 220 drives the first baffle 210 to rotate through the first force application group set on the connecting rod 220, wherein the first baffle 210 is provided with one or more.

[0080] Furthermore, when the real-time wind speed is within the range of the second wind speed, the connecting rod 220 rotates at a second angle. The connecting rod 220 drives the first baffle 210 and the second baffle 210 to rotate through the first force application group and the second force application group set on the connecting rod 220. There is one or more of the first baffle 210 and the second baffle 210.

[0081] Furthermore, when the real-time wind speed is within the range of the third wind speed, the connecting rod 220 rotates at a third angle. The connecting rod 220 drives the first baffle 210, the second baffle 210, and the third baffle 210 to rotate through the first force application group, the second force application group, and the third force application group set on the connecting rod 220. There is one or more of the first baffle 210, the second baffle 210, and the third baffle 210.

[0082] In this embodiment, the first angle is set to satisfy angle = 0.5031 × V 2+11.051×V, set the second angle to satisfy angle=0.7731×V 2 +1.4277×V, set the third angle to satisfy angle=0.311×V 2 +1.8558×V, where V is the real-time wind speed.

[0083] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0084] Multiple asynchronously activated baffles 210 are installed at the air inlet 120, which communicates with the flow channel 110. This allows for airflow guidance as different numbers of baffles 210 are switched from a second position to a first position when airflow passes through the flow channel 110 at different velocities. This guides the airflow from inside the flow channel 110 into the housing 10 through the air inlet 120. Specifically, as the gas velocity inside the flow channel 110 gradually increases, the baffles 210 effectively replenish the housing 10 with air, preventing the performance issues associated with top-mounted heat exchangers due to insufficient airflow.
