[0042] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0043] In small-scale construction machinery, taking a mini excavator as an example, a commonly used heat dissipation method is to use the natural wind brought by the rotation of the suction fan connected to the engine to dissipate the heat of the engine coolant and hydraulic oil.

[0044] In order to improve the heat dissipation performance of the heat dissipation system, the inventor of the present application has been constantly thinking and keenly discovered that the commonly used structures of existing micro excavators have the following two characteristics: First, due to the limited space of the micro excavator, the condenser in the air-conditioning system is often arranged in series with the radiator and arranged at the upwind port. The downwind port is where the fan is located, and the relative positions of the components are engine-fan-radiator-condenser; Second, in order to ensure the cooling effect of the air conditioner, the windward area of ​​the condenser is large.

[0045] Because the radiator and condenser are arranged in series, natural wind needs to flow through the condenser before it can cool the radiator. In addition, the condenser is large in size. When natural wind flows through the condenser, it is inevitable that wind resistance increases, wind speed decreases, air volume decreases, and temperature increases. 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 its heat dissipation effect well.

[0046] In addition, excavators work in different regions and countries. Different temperatures, humidity, working conditions and work intensities have different effects on the engine coolant temperature and hydraulic oil temperature. In some cases, the heat dissipation demand for water radiators is higher, and in some cases, the heat dissipation demand for oil radiators is higher. However, for the commonly used structure of existing micro excavators, the relative positions of the radiator and condenser are determined in the design stage and then fixed, and cannot be adjusted again. This leads to redundant heat dissipation of one of the water radiator and the oil radiator, while the heat dissipation of the other side is tight. In severe cases, the heat dissipation of the tight side is continuously insufficient, which will cause the temperature to continue to rise, resulting in a high temperature alarm. Continuing to work will cause damage to the product.

[0047] In view of this, if Figure 1 and Figure 2 As shown, the first aspect of the present application provides a novel heat dissipation device, which includes a heat dissipation module 1, a condenser 2 and a heat dissipation fan 3. The heat dissipation module 1 is provided with a coolant radiator 11 and a hydraulic oil radiator 12, and the heat dissipation fan 3 is used to air-cool the condenser 2 and the coolant radiator 11 and the hydraulic oil radiator 12 in the heat dissipation module 1. The heat dissipation fan 3, the heat dissipation module 1 and the condenser 2 are arranged in sequence along a first direction L1, and the second direction L2 is staggered with the first direction L1. At least one of the heat dissipation fan 3, the heat dissipation module 1 and the condenser 2 can move relative to each other in a direction staggered with the first direction to adjust the air-cooled heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12.

[0048] It is understandable to those skilled in the art that at least one of the heat dissipation fan 3, the heat dissipation module 1 and the condenser 2 can be relatively movable, for example, the heat dissipation module 1 can be fixed in position, and the heat dissipation fan 3 and the condenser 2 can be relatively movable relative to the heat dissipation module 1; or, the heat dissipation fan 3 can be fixed in position, and the heat dissipation module 1 and the condenser 2 can be relatively movable relative to the heat dissipation fan 3; or, any one of the heat dissipation fan 3, the heat dissipation module 1 and the condenser 2 can be relatively movable relative to the other two; or, the heat dissipation fan 3 and the heat dissipation module 1 can be fixed in position, and the condenser 2 can be relatively movable relative to the heat dissipation module 1 and the heat dissipation fan 3, etc. The positional movement of the heat dissipation fan 3, the heat dissipation module 1 and the condenser 2 can be automatically driven by a power component, or can also 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 cooling module 1 and the condenser 2 can move relative to each other in a direction intersecting with the first direction, the effective heat dissipation wind 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, so that the cooling air volume of the coolant radiator and the hydraulic oil radiator can be adaptively optimized according to actual needs, and the heat dissipation of the coolant radiator 11 and the hydraulic oil radiator 12 can be balanced, and the heat dissipation of one of them will not be too high while the heat dissipation of the other is redundant. Therefore, the heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12 can be adjusted under different climates and working conditions, so as to maximize the heat dissipation capacity and heat dissipation efficiency of the heat dissipation device, and effectively improve the heat dissipation efficiency and the life of the heat dissipation device.

[0050] For example, when the heat dissipation demand of the coolant radiator 11 and the heat dissipation demand of the hydraulic oil radiator 12 are both at a medium balanced level, the position of at least one of the cooling fan 3, the cooling module 1 and the condenser 2 can be adjusted so that the air-cooled heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12 is at a medium balanced level. When the heat dissipation demand of the coolant radiator 11 and the heat dissipation demand of the hydraulic oil radiator 12 are reduced at the same time, the position of at least one of the cooling fan 3, the cooling module 1 and the condenser 2 can be adjusted so that the air-cooled heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12 is at a relatively low level. When the heat dissipation demand of the coolant radiator 11 and the heat dissipation demand of the hydraulic oil radiator 12 are increased at the same time, the position of at least one of the cooling fan 3, the cooling module 1 and the condenser 2 can be adjusted so that the air-cooled heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12 is at a relatively high level. When the heat dissipation demand of the coolant radiator 11 increases and the heat dissipation 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 movably adjusted so that the air-cooled heat dissipation rate of the coolant radiator 11 is at a relatively high level, and the air-cooled heat dissipation rate of the hydraulic oil radiator 12 is at a relatively low level. When the heat dissipation demand of the coolant radiator 11 decreases and the heat dissipation 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 movably adjusted so that the air-cooled heat dissipation rate of the coolant radiator 11 is at a relatively low level, and the air-cooled heat dissipation rate of the hydraulic oil radiator 12 is at a relatively high level.

[0051] For the specific moving position of at least one of the cooling fan 3, the cooling module 1 and the condenser 2, a corresponding preset program can be designed according to the actual structure of the cooling device. For example, during the design and testing phase of the preset program, the condenser 2 can be fixed at different positions relative to the cooling module 1, such as Figure 3As shown in the figure, a coordinate system is established to measure 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, so as to establish a scatter plot. Then, when the heat dissipation demand of the excavator for the coolant radiator 11 and the hydraulic oil radiator 12 changes, the coordinate position of the condenser 2 that is more suitable for this scenario can be obtained through the scatter plot. It should be noted that the heat dissipation in the scatter plot cannot be completely regarded as the value of the specific heat dissipation under different climates and working conditions, but it can provide a reference for the relative heat dissipation capacity and trend changes of the coolant radiator 11 and the hydraulic oil radiator 12 under different coordinates. Figure 3 As shown, there are 5 coordinate positions of the condenser 2. Of course, in actual design and testing, more coordinate positions will be measured, and patterns can be found in the scatter plot to fit the curve, so as to achieve infinite 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 the coolant radiator 11 and the hydraulic oil radiator 12 can be assembled together. The coolant radiator 11 and the hydraulic oil radiator 12 are arranged side by side along the second direction L2, and the second direction L2 can be any direction that is staggered with the first direction L1. For example, when the cooling fan 3, the heat dissipation module 1 and the condenser 2 are arranged in sequence along the front-to-back direction, the coolant radiator 11 and the hydraulic oil radiator 12 can be arranged side by side along the up-down direction or the left-to-right direction. The heat dissipation area of ​​the coolant radiator 11 and the hydraulic oil radiator 12 on the side facing the condenser 2 can be set according to actual operation and design requirements. For example, the heat dissipation area of ​​the coolant radiator 11 on the side facing the condenser 2 can be set to be larger than the heat dissipation area of ​​the hydraulic oil radiator 12 on the side facing the condenser 2.

[0053] In addition, the second direction L2 is arranged alternately with the first direction L1, and the second direction L2 may be perpendicular to the first direction L1, or the second direction L2 may be substantially 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 the coolant radiator 11, the hydraulic oil radiator 12, the cooling fan 3, and the condenser 2 are well known to those skilled in the art, and do not belong to the core improvement part of the present application, so they will not be repeated here.

[0055] In some specific embodiments, the heat dissipation device further includes a driving module 4, which is used to drive at least one of the heat dissipation fan 3, the heat dissipation module 1 and the condenser 2 to move relative to each other. The driving module 4 may include an electric driving mechanism or a hydraulic driving mechanism. In order to achieve intelligent adjustment of the position of the condenser 2, in some specific embodiments, the heat dissipation device may further include a controller connected to the driving module 4, and the controller is configured as follows:

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

[0057] According to the real-time working condition parameters of the operating machine, the driving module 4 is controlled to act according to a preset program to drive at least one of the cooling fan 3, the cooling module 1 and the condenser 2 to move relatively.

[0058] According to different working parameters of the operating machine, the relative position adjustment between the cooling fan 3, the cooling module 1 and the condenser 2 is also different. In the preset program, the corresponding preset positions can be pre-set according to different working parameters of the operating machine, so that the controller can control the action of the driving module 4 according to the real-time working parameters of the operating machine to drive at least one of the cooling fan 3, the cooling module 1 and the condenser 2 to move to the preset position, thereby realizing intelligent adjustment.

[0059] In some specific embodiments, the real-time working condition parameters of the working machine may include the coolant temperature of the coolant radiator 11 and the hydraulic oil temperature of the hydraulic oil radiator 12. At this time, the heat dissipation device may also include a first temperature sensor and a second temperature sensor, the first temperature sensor is used to detect the coolant temperature of the coolant radiator 11, and the second temperature sensor is used to detect the hydraulic oil temperature of the hydraulic oil radiator 12. The controller can obtain the coolant temperature detected by the first temperature sensor and the hydraulic oil temperature detected by the second temperature sensor through the data acquisition device.

[0060] In some specific embodiments, the real-time working condition parameters of the working machine may also include one or more of the working parameters of the working machine, the ambient temperature and the ambient humidity. The working parameters of the working machine may include, for example, the working gear of the engine, the type of the working mechanism, etc. The working parameters, ambient temperature and ambient humidity of the working machine may be obtained by the controller communicating with the corresponding sensors, automatically inputting or manually inputting.

[0061] In some specific embodiments, the step of controlling the driving module 4 to act according to a preset program according to the real-time working condition parameters of the operating machine 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] Determine that the coolant temperature is outside the first optimal temperature range and / or the hydraulic oil temperature is outside the second optimal temperature range, and control the drive module 4 to drive the cooling fan 3, the cooling module 1 and the condenser 2 to move to the corresponding preset position according to the coolant temperature, the hydraulic oil temperature and the operating parameters of the operating machine.

[0063] The first optimal temperature range and the second optimal temperature range can be set according to actual operation requirements and specific configuration parameters of the construction machinery. Under different working 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 temperature of the coolant and the hydraulic oil can be relatively optimally adjusted.

[0064] In some specific embodiments, the controller may also be configured to:

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

[0066] The following will be as follows Figure 1 and Figure 2 The specific implementation shown is used to illustrate the heat dissipation device of the present application. In this specific implementation, the positions of the heat dissipation fan 3 and the heat dissipation module 1 are fixed, and the condenser 2 can be moved relative to the heat dissipation module 1 and the heat dissipation fan 3. In this way, it is not only easy to manufacture, but also can reduce the manufacturing cost. At this time, the driving module 4 can be connected to the condenser 2 and can drive the condenser 2 to move in a direction interlaced with the first direction L1, so as to adjust the shielding position and shielding area of ​​the condenser 2 to the coolant radiator 11 and the hydraulic oil radiator 12, so as to adjust the heat dissipation rate of the coolant radiator 11 and the hydraulic oil radiator 12, give full play to the maximum heat dissipation capacity of the heat dissipation device, and effectively improve the heat dissipation efficiency and the life 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 perpendicular to each other, that is, the first direction L1 is perpendicular to the third direction L3 and the fourth direction L4 respectively, the third direction L3 is perpendicular to the fourth direction L4, and the coolant radiator 11 and the hydraulic oil radiator 12 are arranged side by side along the third direction L3. Based on actual operation 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 arranged on the outer end of the cooling module 1 along the first direction L1, and is relatively close to the coolant radiator 11 along the third direction L3 and close to one end of the cooling 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 shielding position and shielding 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 in the embodiment, the condenser 2 can be adjusted 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 take condenser 2 as Figure 3 The heat dissipation device of the present application is described by taking the five adjustment 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 the position coordinates where the heat dissipation capacity of the coolant radiator 11 and the heat dissipation capacity of the hydraulic oil radiator 12 are relatively balanced. When the heat dissipation requirements of the coolant radiator 11 and the heat dissipation requirements of the hydraulic oil radiator 12 are average, the condenser 2 can be moved to A0 (X0, Y0), at which time the heat dissipation capacity of the coolant radiator 11 and the heat dissipation capacity of the hydraulic oil radiator 12 are relatively balanced. Among them, when the condenser 2 moves to A0 (X0, Y0), in 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 respectively.

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

[0071] If the heat dissipation requirements of the coolant radiator 11 and the hydraulic oil radiator 12 are reduced at the same time, the condenser 2 can be moved to A1 (X1, Y1), where A1 (X1, Y1) is the position coordinate where the heat dissipation capabilities of the coolant radiator 11 and the hydraulic oil radiator 12 are both relatively weak. When the condenser 2 moves from A0 (X0, Y0) to A1 (X1, Y1), the condenser 2 increases the shielding area of ​​the cooling fan 3 in the projection of the first direction L1. For example, when the condenser 2 is at A1 (X1, Y1), it can be set to have the largest shielding area for the cooling fan 3, or even completely shield the cooling fan 3.

[0072] If the heat dissipation demand of the coolant radiator 11 increases and the heat dissipation demand of the hydraulic oil radiator 12 decreases at this time, the condenser 2 can be moved to A2 (X2, Y2), where A2 (X2, Y2) is the position coordinate where the heat dissipation capacity of the coolant radiator 11 is relatively strong and the heat dissipation capacity of the hydraulic oil radiator 12 is relatively weak. Among them, when the condenser 2 moves from A0 (X0, Y0) to A2 (X2, Y2), in the projection of the first direction L1, the condenser 2 increases the shielding area of ​​the hydraulic oil radiator 12 and reduces the shielding area of ​​the cooling fan 3. For example, when the condenser 2 is at A2 (X2, Y2), it can be set to have the largest shielding area for the hydraulic oil radiator 12, and can even completely shield the hydraulic oil radiator 12.

[0073] If the heat dissipation demand of the coolant radiator 11 decreases and the heat dissipation demand of the hydraulic oil radiator 12 increases at this time, the condenser 2 can be moved to A3 (X3, Y3), which is the position coordinate where the heat dissipation capacity of the coolant radiator 11 is weak and the heat dissipation capacity of the hydraulic oil radiator 12 is strong. Among them, when the condenser 2 moves from A0 (X0, Y0) to A3 (X3, Y3), in the projection of the first direction L1, the condenser 2 increases the shielding area of ​​the coolant radiator 11, partially shields the coolant radiator 11, and reduces the shielding area of ​​the hydraulic oil radiator 12 and the cooling fan 3. If the heat dissipation demand of the coolant radiator 11 and the heat dissipation demand of the hydraulic oil radiator 12 increase at the same time, the condenser can be moved to A4 (X4, Y4), which is the position coordinate where the heat dissipation capacity of the coolant radiator 11 and the hydraulic oil radiator 12 are both strong. When the condenser 2 moves from A0 (X0, Y0) to A4 (X4, Y4), in the projection of the first direction L1, the condenser 2 reduces the shielding area of ​​the coolant radiator 11 and the cooling fan 3. For example, when the condenser 2 is at A4 (X4, Y4), it can be set to minimize the shielding area of ​​the cooling fan 3, or even not shield the cooling fan 3 at all.

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

[0075] Furthermore, if Figure 1 and Figure 2 As shown, the driving module 4 may include a first driving unit and a second driving unit, wherein the first driving unit is used to drive the condenser 2 to move along the third direction L3, and the second driving unit is used to drive the condenser 2 to move along the fourth direction L4. The first direction L1, the third direction L3, and the fourth direction L4 are mutually perpendicular, so that the condenser 2 can be adjusted to various positions on a plane perpendicular to the first direction L1, and the heat dissipation efficiency can be optimally adjusted. The driving structure of the first driving unit and the second driving unit may be various, for example, may include a cylinder driving mechanism or a motor screw driving mechanism.

[0076] Furthermore, in some specific embodiments, 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 along the 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 along the fourth direction, and 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 along the 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 along the third direction, and 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, Figure 2 As shown, the first guide rail 413 and the second guide rail 423 may respectively include a guide rail frame provided with a guide groove and a screw rod rotatably arranged in the guide rail frame, the first driving member and the second driving member may include a motor driving the screw rod to rotate, and the first slider 412 and the second slider 422 may be nut slider members threadedly connected to the screw rod and movably arranged in the guide groove.
