[0034] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0035] like Figure 1 and Figure 2 As shown, the heat dissipation system 100 of this utility model embodiment includes an engine 1 and a heat dissipation component 2. The heat dissipation component 2 includes a cooling fan 21. The engine 1 includes a first output end 11. The axis of the first output end 11 is parallel to or coincides with the axis of rotation of the cooling fan 21. The first output end 11 is in transmission cooperation with the cooling fan 21.
[0036] The heat dissipation system 100 of this utility model simplifies the driving method and power transmission path by setting the axis of the first output end 11 of the engine 1 to be parallel or coincident with the axis of rotation of the cooling fan 21, compared with the form of driving the cooling fan 21 by a pulley or hydraulic motor. The engine 1 can directly drive the cooling fan 21 to rotate, the transmission is reliable, and the heat dissipation efficiency of the heat dissipation system 100 is guaranteed.
[0037] The heat dissipation system of this utility model has a simple structure, reliable transmission and high heat dissipation efficiency, and can effectively dissipate heat and cool down the power system and hydraulic system, thereby improving the heat dissipation efficiency of the heat dissipation system.
[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, the first output terminal 11 is fixedly connected to the shaft of the cooling fan 21 or connected through a coupling, and the first output terminal 11 is used to drive the cooling fan 21 to rotate.
[0039] When the axis of the first output end 11 of the engine 1 coincides with the axis of the rotating shaft of the cooling fan 21, the first output end 11 is fixedly connected to the rotating shaft of the cooling fan 21, which ensures the safe and reliable power transmission between the engine 1 and the cooling fan 21. Alternatively, a coupling can be used to achieve a detachable connection between the first output end 11 of the engine 1 and the rotating shaft of the cooling fan 21, which facilitates the disassembly and replacement of the cooling fan 21 and makes the operation convenient.
[0040] In some embodiments, when the axis of the first output terminal 11 is parallel to the axis of rotation of the cooling fan 21, the transmission connection between the first output terminal 11 and the shaft of the cooling fan 21 can be realized through a gearbox and a clutch. The power adjustment between the first output terminal 11 and the shaft of the cooling fan 21 can also be realized through the gearbox and the clutch, thereby controlling the rotation speed of the cooling fan 21 to achieve different cooling efficiency of the cooling system 100, so as to meet different cooling requirements and improve the effective cooling power of the cooling system 100.
[0041] In some embodiments, the heat dissipation component 2 includes a first heat dissipation network, which is disposed corresponding to the cooling fan 21, and coolant circulates within the first heat dissipation network.
[0042] Specifically, when the cooling fan 21 rotates, the cooling airflow through the cooling fan 21 exchanges heat with the coolant in the first heat dissipation pipe network as it passes through the first heat dissipation pipe network, further reducing the cooling airflow problem and improving cooling efficiency.
[0043] In some embodiments, the heat dissipation component 2 includes a second heat dissipation network, which is arranged parallel to the first heat dissipation network and is located on the side of the first heat dissipation network near the cooling fan 21. Hydraulic oil circulates within the second heat dissipation network.
[0044] A second cooling pipe network is set parallel to the first cooling pipe network. The cooling airflow passing through the first cooling pipe network exchanges heat with the hydraulic oil in the second cooling pipe network, thereby cooling the hydraulic oil and improving the cooling efficiency of the engine 1 and the hydraulic system.
[0045] In some embodiments, such as Figure 2 As shown, the heat dissipation assembly 2 includes a heat sink 22, and the heat sink 22 is provided on at least one of the two axial sides of the cooling fan 21.
[0046] By setting up the heat sink 22, the air passing through the cooling fan 21 can be initially filtered, preventing large impurities from obstructing or damaging the cooling fan 21, ensuring the normal operation of the cooling fan 21, and thus ensuring the heat dissipation efficiency of the heat dissipation system 100. At the same time, the heat sink 22 can exchange heat with the air, thereby reducing the temperature of the heat dissipation component 2 itself, further improving the heat dissipation efficiency, and can also protect both sides of the cooling fan 21 to prevent pipelines or workers from accidentally entering the rotating cooling fan 21 and causing damage to items or personnel, ensuring safety and reliability.
[0047] The following describes a concrete mixer truck according to an embodiment of the present invention.
[0048] like Figure 3 and Figure 4 As shown, the concrete mixer truck of this utility model embodiment includes a frame 200, a cab 300, a mixing tank 400, and a heat dissipation system 100 of any of the above embodiments. The cab 300, the mixing tank 400, and the heat dissipation component 2 are sequentially arranged on the frame 200 along the length direction of the frame 200. The axis of the first output end 11 of the engine 1 extends along the length direction of the frame 200. The inlet and outlet ends of the mixing tank 400 are located on the side near the mixing tank 400 and near the cab 300. The engine 1 includes a second output end, which is connected to the mixing tank 400 in a transmission manner.
[0049] The concrete mixer truck of this utility model has the cab 300, mixing tank 400 and heat dissipation component 2 arranged sequentially along the length of the frame 200, which facilitates the adjustment and control of the overall center of gravity of the vehicle, so as to ensure that the center of gravity of the concrete mixer truck is located in the middle position of the frame 200, and to prevent the concrete mixer truck from overturning during the journey. At the same time, the engine 1 drives the heat dissipation system 100 and the mixing tank 400 simultaneously, which is safe and reliable.
[0050] The concrete mixer truck of this utility model simplifies and optimizes the heat dissipation system 100, thereby simplifying the transmission path between the engine 1 and the heat dissipation component 2, ensuring the heat dissipation efficiency of the heat dissipation system 100. Furthermore, by extending the output shaft of the engine 1 along the length direction of the frame 200, the positions of the engine 1 and the heat dissipation component 2 are optimized, ensuring that the center of gravity of the concrete mixer truck is located in the middle position of the frame 200, thus ensuring the stability of the vehicle during travel and turning, and making it safe and reliable.
[0051] In some embodiments, such as Figure 4 As shown, the frame 200 is provided with two upright plates 3 at intervals corresponding to the heat dissipation component 2. The two upright plates 3 and the frame 200 limit the space for the mounting cavity. The heat dissipation component 2 includes a heat dissipation frame 23, which can be detachably assembled into the mounting cavity.
[0052] Specifically, the upright plate 3 is a U-shaped plate, including a first plate extending along the width direction of the frame 200 and two second plates spaced apart on the first plate. The two second plates and the frame 200 define a mounting cavity for mounting the heat sink frame 23. The two adjacent second plates of the two upright plates 3 are provided with fixing holes, which communicate with the mounting cavity. Limiting units such as fastening bolts and pressure plates that are adjustable in position along the direction perpendicular to the second plate can be installed through the fixing holes to achieve quick fixing of the heat sink frame 23.
[0053] Optionally, the heat sink frame 23 is provided with a size-adaptive limiting hole corresponding to the fixing hole. By shooting a limiting rod through the limiting hole and the mounting hole, the limiting rod simultaneously engages with the limiting hole and the mounting hole to prevent rotation, so as to achieve quick fixation of the heat sink frame 23.
[0054] In some embodiments, such as Figure 4 As shown, the frame 200 is provided with a connecting part 4 extending along the length of the frame 200, and the connecting part 4 is located between two upright plates 3. The connecting part 4 is a guide rail or slide groove with a T-shaped cross section. The heat dissipation frame 23 is slidably assembled on the guide rail or slide groove, and the heat dissipation frame 23 is stopped and cooperated with the guide rail or slide groove in the direction perpendicular to the frame 200.
[0055] By setting the connecting part 4, i.e., the slide or rail, when installing the cooling system 100, the cooling frame 23 can be slid to adjust the position of the cooling fan 21 through the cooperation of the cooling frame 23 and the connecting part 4, thereby realizing the quick assembly and disassembly of the cooling system 100 and the engine 1. The operation is convenient. The cross-section of the guide rail or slide is T-shaped, which can constrain the cooling frame 23 in the direction perpendicular to the frame 200, ensuring the reliability of the connection between the engine 1 and the cooling fan 21, and ensuring the heat dissipation efficiency of the cooling system 100.
[0056] In some embodiments, such as Figure 4As shown, the frame 200 is provided with multiple mounting points 5, and the multiple mounting points 5 are set corresponding to the upright plate 3. The multiple mounting points 5 are used to install the heat sink frame 23.
[0057] Specifically, there are multiple mounting points 5, and these mounting points 5 are arranged in an array between two upright plates 3. The heat dissipation frame 23 is provided with connecting lugs or plugs corresponding to the mounting points 5. When installing the heat dissipation component 2, the heat dissipation frame 23 can be quickly fixed by installing connecting bolts at the connecting lugs on the heat dissipation frame 23, or the heat dissipation frame 23 can be quickly fixed by inserting the plugs on the heat dissipation frame 23 into the mounting points 5. This facilitates the quick installation and disassembly of the heat dissipation component 2 and makes the operation convenient.
