[0009] In some specific embodiments, the heat dissipation device further includes a drive module for driving at least one of the cooling fan, the heat dissipation module, and the condenser to move relative to each other.

[0010] In some specific embodiments, the drive module is connected to the condenser drive and can drive the condenser to move, so as to adjust the condenser's blocking position and blocking area on the cooling fan, the coolant radiator and the hydraulic oil radiator.

[0011] In some specific embodiments, the condenser is provided with a first movable member and a second movable member, and the drive module includes:

[0014] Wherein, the first direction, the third direction, and the fourth direction are perpendicular to each other.

[0015] In some specific embodiments, the cooling fan and the heat dissipation module are fixedly arranged;

[0016] And / or, the angle between the first direction and the second direction is greater than 60° and less than 120°.

[0017] In some specific embodiments, the heat dissipation device further includes a controller connected to the drive module, the controller being configured to:

[0018] Obtain the real-time operating parameters of the machinery;

[0042] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0043] In small construction machinery, taking mini excavators as an example, the common cooling method is to use the natural wind generated by the rotation of the suction fan connected to the engine to cool the engine coolant and hydraulic oil.

[0044] In order to improve the heat dissipation performance of the cooling system, the inventors of this application have been constantly thinking and have keenly discovered that the existing structures of mini excavators have the following two characteristics: First, due to the limited space in mini excavators, the condenser in the air conditioning system is often arranged in series with the radiator and placed at the upper air vent, while the fan is located at the lower air vent. The relative positions of the components are engine-fan-radiator-condenser; Second, in order to ensure the cooling effect of the air conditioning, the condenser has a large frontal area.

[0045] Because the radiator and condenser are arranged in series, natural air must flow through the condenser before it can cool the radiator. In addition, the condenser is relatively large. When natural air flows through the condenser, it is inevitable that the wind resistance will increase, the wind speed will decrease, the air volume will decrease, and the temperature will rise. This will greatly reduce the heat dissipation effect of the radiator. However, the effective heat dissipation area of ​​the radiator that is not blocked by the condenser can still play a good role in heat dissipation.

[0046] Furthermore, the different temperatures, humidity levels, working conditions, and workloads of excavators in different regions and countries all have varying impacts on engine coolant and hydraulic oil temperatures. In some cases, the cooling capacity of the water radiator is more critical, while in others, the cooling capacity of the oil radiator is even higher. However, for the commonly used structure of existing mini excavators, the relative positions of the radiator and condenser are fixed after the design phase and cannot be adjusted again. This leads to a situation where the cooling capacity of one of the water radiators and oil radiators is redundant, while the cooling capacity of the other is insufficient. In severe cases, the insufficient cooling capacity of the other side will cause the temperature to rise continuously, triggering a high-temperature alarm. Continuing to operate will damage the product.

[0047] In view of this, such as Figure 1 and Figure 2 As shown, the first aspect of this application provides a novel heat dissipation device, which includes a heat dissipation module 1, a condenser 2, and a cooling fan 3. The heat dissipation module 1 is equipped with a coolant radiator 11 and a hydraulic oil radiator 12. The cooling fan 3 is used to provide air cooling for the condenser 2 and the coolant radiator 11 and hydraulic oil radiator 12 in the heat dissipation module 1. The cooling fan 3, the heat dissipation module 1, and the condenser 2 are arranged sequentially along a first direction L1, and a second direction L2 is arranged alternately with the first direction L1. At least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can move relative to each other in a direction alternately with the first direction to adjust the air cooling rate of the coolant radiator 11 and the hydraulic oil radiator 12.

[0048] Those skilled in the art will understand that at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can be relatively movable. For example, the position of the heat dissipation module 1 can be fixed, while the cooling fan 3 and the condenser 2 can move relative to the heat dissipation module 1; or, the position of the cooling fan 3 can be fixed, while the heat dissipation module 1 and the condenser 2 can move relative to the cooling fan 3; or, any one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can move relative to the other two; or, the positions of the cooling fan 3 and the heat dissipation module 1 can be fixed, while the condenser 2 can move relative to the heat dissipation module 1 and the cooling fan 3, etc. The movement of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can be automatically driven by a power component, or it can be manually adjusted, etc., and these structural forms should also fall within the protection scope of this application.

[0049] Since at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can move relative to each other in a direction intersecting with the first direction, the effective heat dissipation airflow area of ​​the coolant radiator 11 and the hydraulic oil radiator 12 relative to the cooling fan 3 and / or the windward shielding area relative to the condenser 2 can be changed. This allows for adaptive optimization of the cooling airflow distribution of the coolant radiator and the hydraulic oil radiator according to actual needs, achieving a balanced heat dissipation of the coolant radiator 11 and the hydraulic oil radiator 12. This prevents one side from having excessive heat dissipation while the other side has redundant heat dissipation. Consequently, the heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12 can be adjusted under different climates and operating conditions, maximizing the heat dissipation capacity and efficiency of the heat dissipation device, and effectively improving the heat dissipation efficiency and lifespan of the heat dissipation device.

[0050] For example, when the heat dissipation requirements of both the coolant radiator 11 and the hydraulic oil radiator 12 are at a moderately balanced level, the position of at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can be adjusted to ensure that the air cooling rates of both the coolant radiator 11 and the hydraulic oil radiator 12 are at a moderately balanced level. When the heat dissipation requirements of both the coolant radiator 11 and the hydraulic oil radiator 12 decrease simultaneously, the position of at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can be adjusted to ensure that the air cooling rates of both the coolant radiator 11 and the hydraulic oil radiator 12 are at a relatively low level. When the heat dissipation requirements of both the coolant radiator 11 and the hydraulic oil radiator 12 increase simultaneously, the position of at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can be adjusted to ensure that the air cooling rates of both the coolant radiator 11 and the hydraulic oil radiator 12 are at a relatively high level. When the cooling demand of the coolant radiator 11 increases while the cooling demand of the hydraulic oil radiator 12 decreases, the position of at least one of the cooling fan 3, the cooling module 1, and the condenser 2 can be adjusted to ensure that the air cooling rate of the coolant radiator 11 is at a relatively high level, and the air cooling rate of the hydraulic oil radiator 12 is at a relatively low level. Conversely, when the cooling demand of the coolant radiator 11 decreases while the cooling demand of the hydraulic oil radiator 12 increases, the position of at least one of the cooling fan 3, the cooling module 1, and the condenser 2 can be adjusted to ensure that the air cooling rate of the coolant radiator 11 is at a relatively low level, and the air cooling rate of the hydraulic oil radiator 12 is at a relatively high level.

[0051] The specific moving position of at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 can be designed according to a corresponding preset program based on the actual structure of the heat dissipation device. For example, during the design and testing phase of the preset program, the condenser 2 can be fixed in different positions relative to the heat dissipation module 1, such as... Figure 3A coordinate system was established as shown, and the relationship between the heat dissipation of the coolant radiator 11, the heat dissipation of the hydraulic oil radiator 12, and the different coordinate positions of the condenser 2 was measured. A scatter plot was then created, allowing the condenser 2's coordinate position to be determined when the excavator's heat dissipation requirements for the coolant radiator 11 and hydraulic oil radiator 12 change. It should be noted that the heat dissipation values ​​in the scatter plot cannot be considered as specific values ​​under different climates and operating conditions, but they can provide a reference for the relative heat dissipation capabilities and trends of the coolant radiator 11 and hydraulic oil radiator 12 at different coordinate positions. Figure 3 As shown, the condenser 2 has 5 coordinate positions. Of course, in actual design and testing, more coordinate positions will be measured. Patterns can be found in the scatter plot, and curves can be fitted to achieve stepless adjustment of the heat dissipation capacity of the coolant radiator 11 and the hydraulic oil radiator 12 as much as possible.

[0052] Optionally, the coolant radiator 11 and the hydraulic oil radiator 12 can be integrated on the base frame of the heat dissipation module 1, or they can be assembled together. The coolant radiator 11 and the hydraulic oil radiator 12 are arranged side-by-side along a second direction L2, which can be any direction intersecting the first direction L1. For example, when the cooling fan 3, the heat dissipation module 1, and the condenser 2 are arranged sequentially in a front-to-back direction, the coolant radiator 11 and the hydraulic oil radiator 12 can be arranged side-by-side in a vertical or horizontal direction. The heat dissipation area of ​​the coolant radiator 11 and the hydraulic oil radiator 12 facing the condenser 2 can be set according to actual operation and design needs. For example, the heat dissipation area of ​​the coolant radiator 11 facing the condenser 2 can be set to be larger than that of the hydraulic oil radiator 12 facing the condenser 2.

[0053] Furthermore, the second direction L2 is staggered with the first direction L1. The second direction L2 may be perpendicular to the first direction L1, or the second direction L2 may be approximately perpendicular to the first direction L1. Alternatively, the angle between the first direction L1 and the second direction L2 may be greater than 60° and less than 90°, or the angle between the first direction L1 and the second direction L2 may be greater than 90° and less than 120°.

[0054] It should be noted that the structural principles of components such as coolant radiator 11, hydraulic oil radiator 12, cooling fan 3, and condenser 2 are well known to those skilled in the art and are not part of the core improvements of this application, so they will not be described in detail here.

[0055] In some embodiments, the heat dissipation device further includes a drive module 4, which drives at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 to move relative to each other. The drive module 4 may include an electric drive mechanism or a hydraulic drive mechanism, etc. To achieve intelligent adjustment of the position of the condenser 2, in some embodiments, the heat dissipation device may also include a controller connected to the drive module 4, the controller being configured to:

[0056] Obtain real-time operating parameters of the machinery;

[0057] The drive module 4 is controlled to operate according to a preset program based on the real-time operating parameters of the machinery to drive at least one of the cooling fan 3, the cooling module 1, and the condenser 2 to move relative to each other.

[0058] Depending on the operating parameters of the machinery, the relative positions of the cooling fan 3, the heat dissipation module 1, and the condenser 2 will also vary. In the preset program, corresponding preset positions can be pre-set according to different operating parameters of the machinery, allowing the controller to control the drive module 4 to move at least one of the cooling fan 3, the heat dissipation module 1, and the condenser 2 to the preset position based on the real-time operating parameters of the machinery, thus achieving intelligent adjustment.

[0059] In some specific embodiments, the real-time operating parameters of the machinery may include the coolant temperature of the coolant radiator 11 and the hydraulic oil temperature of the hydraulic oil radiator 12. In this case, the cooling device may also include a first temperature sensor and a second temperature sensor. The first temperature sensor detects the coolant temperature of the coolant radiator 11, and the second temperature sensor detects the hydraulic oil temperature of the hydraulic oil radiator 12. The controller can acquire the coolant temperature detected by the first temperature sensor and the hydraulic oil temperature detected by the second temperature sensor via a data acquisition unit.

[0060] In some specific implementations, the real-time operating parameters of the working machinery may also include one or more of the following: the working parameters of the working machinery, ambient temperature, and ambient humidity. The working parameters of the working machinery may include, for example, the engine's operating gear and the type of the working mechanism. The working parameters, ambient temperature, and ambient humidity can be obtained through automatic input or manual input via communication between the controller and corresponding sensors.

[0061] In some specific embodiments, the step of controlling the drive module 4 to operate according to a preset program based on the real-time operating parameters of the machinery to drive at least one of the cooling fan 3, the cooling module 1, and the condenser 2 to move relative to each other may specifically include:

[0062] If the coolant temperature is outside the first optimal temperature range and / or the hydraulic oil temperature is outside the second optimal temperature range, the drive module 4 is controlled to move at least one of the cooling fan 3, the cooling module 1 and the condenser 2 to the corresponding preset position based on the coolant temperature, the hydraulic oil temperature and the operating parameters of the working machinery.

[0063] The first and second optimal temperature ranges can be set according to actual operational needs and the specific configuration parameters of the engineering machinery. Under different operating conditions, the coolant temperature can have different first optimal temperature ranges, and the hydraulic oil temperature can have different second optimal temperature ranges. In this way, the relative optimization of the temperature control of the coolant and hydraulic oil can be achieved.

[0064] In some specific implementations, the controller may also be configured as follows:

[0065] Once the coolant temperature is determined to be within the first optimal temperature range and the hydraulic oil temperature is within the second optimal temperature range, the cooling fan 3, the cooling module 1, and the condenser 2 are controlled to maintain their current positions.

[0066] The following will be as follows Figure 1 and Figure 2 The specific embodiment shown will be used to describe the heat dissipation device of this application. In this specific embodiment, the positions of the cooling fan 3 and the heat dissipation module 1 are fixed, while the condenser 2 can be moved relative to the heat dissipation module 1 and the cooling fan 3. This not only facilitates manufacturing but also reduces manufacturing costs. At this time, the drive module 4 can be driven to connect with the condenser 2 and can drive the condenser 2 to move in a direction intersecting the first direction L1, so as to adjust the blocking position and blocking area of ​​the condenser 2 on the coolant radiator 11 and the hydraulic oil radiator 12. This allows for adjustment of the heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12, maximizing the heat dissipation capacity of the heat dissipation device and effectively improving the heat dissipation efficiency and lifespan of the heat dissipation device.

[0067] like Figure 1 and Figure 2As shown, the first direction L1, the third direction L3, and the fourth direction L4 are mutually perpendicular, that is, the first direction L1 is perpendicular to the third direction L3 and the fourth direction L4, respectively, and the third direction L3 is perpendicular to the fourth direction L4. The coolant radiator 11 and the hydraulic oil radiator 12 are arranged side by side along the third direction L3. Based on actual operational needs, the width of the coolant radiator 11 along the third direction L3 is greater than the width of the hydraulic oil radiator 12 along the third direction L3. The cooling fan 3 is installed on the outer end of the heat dissipation module 1 along the first direction L1, and is positioned relatively close to the coolant radiator 11 along the third direction L3 and close to one end of the heat dissipation module 1 along the fourth direction L4. The condenser 2 can move along the third direction L3 and the fourth direction L4 to change the blocking position and blocking area of ​​the cooling fan 3, the coolant radiator 11, and the hydraulic oil radiator 12.

[0068] Specifically, according to Figure 1 In the coordinate system established by the heat dissipation device, the condenser 2 can be adjusted in position along the X-axis (i.e., the third direction L3) and the Y-axis (i.e., the fourth direction L4). For example, the adjustment position coordinates of the condenser 2 can be A0(X0,Y0), A1(X1,Y1)...A n (X n ,Y n The following will use condenser 2 as an example. Figure 3 The heat dissipation device of this application will be described using five adjustable position coordinates A0(X0,Y0), A1(X1,Y1), A2(X2,Y2), A3(X3,Y3), and A4(X4,Y4) as examples.

[0069] like Figure 3 As shown, A0(X0,Y0) corresponds to a position coordinate where the heat dissipation capacity of the coolant radiator 11 and the hydraulic oil radiator 12 are relatively balanced. When the heat dissipation requirements of the coolant radiator 11 and the hydraulic oil radiator 12 are moderate, the condenser 2 can be moved to A0(X0,Y0). At this point, the heat dissipation capacity of the coolant radiator 11 and the hydraulic oil radiator 12 are relatively balanced. When the condenser 2 is moved to A0(X0,Y0), on the projection of the first direction L1, the condenser 2 partially blocks the cooling fan 3, the coolant radiator 11, and the hydraulic oil radiator 12.

[0070] Furthermore, under normal circumstances, the condenser 2 can operate at the coordinates corresponding to point A0(X0,Y0). When the position of the condenser 2 is adjusted according to the real-time operating parameters of the working machinery, the position of the condenser 2 is moved.

[0071] If the cooling demand of both the coolant radiator 11 and the hydraulic oil radiator 12 decreases simultaneously, the condenser 2 can be moved to A1(X1,Y1), where A1(X1,Y1) represents the coordinates of a position where the cooling capacity of both the coolant radiator 11 and the hydraulic oil radiator 12 is relatively weak. Specifically, when the condenser 2 moves from A0(X0,Y0) to A1(X1,Y1), its obstruction area on the cooling fan 3 increases in the projection along the first direction L1. For example, when the condenser 2 is at A1(X1,Y1), it can be set to maximize its obstruction area on the cooling fan 3, or even completely obstruct it.

[0072] If the cooling demand of the coolant radiator 11 increases while the cooling demand of the hydraulic oil radiator 12 decreases, the condenser 2 can be moved to A2(X2,Y2), where A2(X2,Y2) represents the coordinates of a position where the coolant radiator 11 has a stronger cooling capacity and the hydraulic oil radiator 12 has a weaker cooling capacity. Specifically, when the condenser 2 moves from A0(X0,Y0) to A2(X2,Y2), on the projection of the first direction L1, the condenser 2 increases the area it obstructs from the hydraulic oil radiator 12 and reduces the area it obstructs from the cooling fan 3. For example, when the condenser 2 is at A2(X2,Y2), it can be set to maximize the area it obstructs from the hydraulic oil radiator 12, or even completely obstruct it.

[0073] If the cooling demand of the coolant radiator 11 decreases while the cooling demand of the hydraulic oil radiator 12 increases, the condenser 2 can be moved to A3(X3,Y3), where A3(X3,Y3) represents the coordinates of a position where the cooling capacity of the coolant radiator 11 is relatively weak and the cooling capacity of the hydraulic oil radiator 12 is relatively strong. When the condenser 2 moves from A0(X0,Y0) to A3(X3,Y3), on the projection of the first direction L1, the condenser 2 increases the area obstructing the coolant radiator 11, partially obstructing it, and reduces the area obstructing the hydraulic oil radiator 12 and the cooling fan 3. If the cooling demand of both the coolant radiator 11 and the hydraulic oil radiator 12 increases simultaneously, the condenser can be moved to A4(X4,Y4), where A4(X4,Y4) represents the coordinates of a position where the cooling capacity of both the coolant radiator 11 and the hydraulic oil radiator 12 is relatively strong. When the condenser 2 moves from A0(X0,Y0) to A4(X4,Y4), its obstruction area on the coolant radiator 11 and cooling fan 3 is reduced in the projection of the first direction L1. For example, when the condenser 2 is in A4(X4,Y4), its obstruction area on the cooling fan 3 can be minimized, or even completely eliminated.

[0074] Of course, in actual design and testing, more coordinates will be measured. Figure 3Find patterns in the coordinate graph shown, fit the curve, and try to achieve stepless adjustment of the heat dissipation capacity of the coolant radiator 11 and the hydraulic oil radiator 12.

[0075] Furthermore, such as Figure 1 and Figure 2 As shown, the drive module 4 may include a first drive unit and a second drive unit. The first drive unit drives the condenser 2 to move along a third direction L3, and the second drive unit drives the condenser 2 to move along a fourth direction L4. The first direction L1, the third direction L3, and the fourth direction L4 are all perpendicular to each other, thus allowing the condenser 2 to be adjusted to different positions on a plane perpendicular to the first direction L1, achieving optimal adjustment of heat dissipation efficiency. The drive structure of the first and second drive units can be varied, for example, it may include a hydraulic cylinder drive mechanism or a motor screw drive mechanism.

[0076] Furthermore, in some specific implementations, such as Figure 1 and Figure 2 As shown, the condenser 2 may be provided with a first movable member 411 and a second movable member 421. The first driving unit includes a first driving member, a first slider 412, and a first guide rail 413 extending in a third direction. The first slider 412 is movably disposed on the first guide rail 413 and can slide along the first guide rail 413 under the drive of the first driving member. The first slider 412 is provided with a first guide rod 414 extending in a fourth direction. The first movable member 411 is movably disposed on the first guide rod 414 and can move along the first guide rod 414. The second driving unit includes a second driving member, a second slider 422, and a second guide rail 423 extending in a fourth direction. The second slider 422 is movably disposed on the second guide rail 423 and can slide along the second guide rail 423 under the drive of the second driving member. The second slider 422 is provided with a second guide rod 424 extending in a third direction. The second movable member 421 is movably disposed on the second guide rod 424 and can move along the second guide rod 424.

[0077] Specifically, such as Figure 2 As shown, the first guide rail 413 and the second guide rail 423 may each include a guide rail frame with a guide groove and a lead screw rotatably disposed in the guide rail frame. The first driving member and the second driving member may include a motor for driving the lead screw to rotate. The first slider 412 and the second slider 422 may be nut slider components threadedly connected to the lead screw and movably disposed in the guide groove. The first movable member 411 and the second movable member 421 are pipe fittings welded to the condenser 2. The axis of the first movable member 411 is arranged along the third direction L3, and the axis of the second movable member 421 is arranged along the fourth direction L4. The first guide rod 414 is movably inserted through the first movable member 411, and the second guide rod 424 is movably inserted through the second movable member 421.

[0078] The first guide rail 413 is mounted on the heat dissipation module 1, and two sets are spaced apart along the fourth direction L4. Each set of first guide rails 413 is provided with two first sliders 412 spaced apart along the third direction L3. Two first movable parts 411 are spaced apart along the third direction L3, and two corresponding first guide rods 414 are provided. The two ends of the first guide rods 414 are respectively fixedly connected to the first sliders 412 on the two sets of first guide rails 413.

[0079] The second guide rail 423 is mounted on the heat dissipation module 1, and two sets are spaced apart along the third direction L3. Each set of second guide rails 423 is provided with two second sliders 422 spaced apart along the fourth direction L4.

This work machine can be an excavator, a loader, etc.

[0082] In summary, the heat dissipation device and operating machinery of this application adopt an adaptive closed-loop control method, which can dynamically detect and monitor the coolant temperature and hydraulic oil temperature in real time. Based on different operating parameters, it adjusts the relative positions of the cooling fan, heat dissipation module, and condenser to adapt and distribute the heat dissipation of the coolant radiator and hydraulic oil radiator. This allows for optimal adjustment of the coolant and hydraulic oil temperatures according to the working conditions, achieving better control and preventing one of the coolant radiator or hydraulic oil radiator from becoming excessively hot while the other experiences redundant heat dissipation. Under different climates and operating conditions, the heat dissipation device can achieve maximum heat dissipation efficiency, effectively improving the service life of the radiator.
