Description

Technical Field

[0001] The present invention relates to the field of heat dissipation of forklifts, and more particularly to a heat dissipation structure for forklifts. Background Art

[0002] In order to meet the needs of efficient and convenient cargo handling in warehousing and logistics, forklifts came into being. They use their own mechanical power to achieve operations such as forking, lifting and handling of goods, greatly improving the efficiency and safety of cargo handling. During the operation of the forklift, its internal power device (including engine, electrical equipment, hydraulic equipment, etc.) will generate a lot of heat energy. In order to ensure that the forklift can operate stably for a long time, a heat dissipation structure is usually installed inside the forklift to achieve timely heat dissipation of its internal power device;

[0003] The heat dissipation structure inside the forklift is usually composed of coolant, radiator and fan. The operation of the fan can not only cool down the circulating coolant by cooperating with the radiator, but also realize the cooling of the power device inside the forklift by blowing air.

[0004] However, the internal fan of the existing forklift is usually installed at the front end of the power unit. Since the components of the main components of the power unit, the engine, electrical equipment, and hydraulic equipment, are relatively complex, and there are shielding between some components, when the fan blows air from one side to dissipate heat to the several components, the airflow will be continuously obstructed during the flow process, reducing the overall effect of the airflow on the cooling of the several components.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This solution can achieve precise and concentrated air blowing and heat dissipation from the bottom of the engine, electrical equipment and hydraulic equipment through the coordination of the partition, the air collecting box and multiple exhaust ports, thereby effectively improving the air blowing and heat dissipation effect of the equipment on the equipment. At the same time, the layout of the air collecting box for separating the equipment can effectively reduce the thermal interference between the equipment during operation.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0050] See also Figures 1 to 16 A heat dissipation structure for a forklift includes a forklift body 1, an air collecting box 2 is fixedly installed in the forklift body 1, and a heat dissipation component 4 is arranged in the air collecting box 2.

[0051] like Figure 1 - Figure 4 , Fig.13 As shown, an engine 13 is installed on the air collecting box 2, a cooling fan 11 is installed on the engine 13, an electrical device 14 is installed on the air collecting box 2, and a hydraulic device 15 is installed on the air collecting box 2.

[0052] The engine 13 is the core component of the power device in the forklift body 1 (especially internal combustion forklifts), and is the power source when the forklift body 1 is in operation, while the electrical equipment 14 and the hydraulic equipment 15 are components that assist the operation of the engine 13. When the forklift body 1 is in operation, the electrical equipment 14 will transmit current to the inside of the engine 13, prompting the engine 13 to start running, and the operation of the hydraulic equipment 15 can convert the mechanical energy generated during the operation of the engine 13 into hydraulic energy, driving the lifting and tilting operations of the forklift body 1. During the operation, the three cooperate and restrict each other. Their specific working principles and components are all existing mature technologies and mechanical parts, and will not be further elaborated here.

[0053] like Figure 1 , Figure 3 - Fig.11 As shown, the heat dissipation assembly 4 includes a partition plate 42 fixedly mounted at the lower end of the air collecting box 2, two partition plates 42 are provided, a plurality of slide grooves 415 are provided in the air collecting box 2, a sealing plate 43 is sealingly and slidably mounted between the two corresponding slide grooves 415, and the sealing plates 43 are sealingly and slidably mounted in the air collecting box 2, and a pushing component is installed between the sealing plate 43 and the forklift body 1;

[0054] A round rod 410 is rotatably mounted on the sealing plate 43, an agitator 412 is fixedly mounted on the round rod 410, a driving component is installed between the round rod 410 and the air collecting box 2, a linearly evenly distributed one-way exhaust pipe 41 is fixedly mounted in the air collecting box 2, and a plurality of exhaust ports 44 are opened on the air collecting box 2.

[0055] A partition 3 is fixedly installed between the forklift body 1 and the air collecting box 2, and an air regulating component 7 is arranged on the partition 3. A one-way air intake pipe 5 is fixedly connected between the partition 3 and the air collecting box 2. A radiator 6 is fixedly installed in the forklift body 1, and a flow regulating component 8 is arranged on the radiator 6.

[0056] When the engine 13, the electrical equipment 14 and the hydraulic equipment 15 cooperate and restrict each other to drive the forklift body 1 to operate, the engine 13 will generate a large amount of heat due to the mechanical movement of the internal components, and the electrical equipment 14 will generate heat due to the flow of current during operation, and the hydraulic equipment 15 will also generate heat due to the flow and compression of the internal hydraulic oil. If the heat dissipation treatment is not performed on the several parts in time, it is easy to cause damage not only to the internal components themselves, but also to other parts connected to them.

[0057] Therefore, when the engine 13, the electrical equipment 14 and the hydraulic equipment 15 cooperate and restrict each other to drive the forklift body 1 to start running, the coolant inside the radiator 6 must first be input into the engine 13 through the existing liquid pump through the cooperation of the conduit 81 and the liquid replenishing tube. During the flow of the coolant in the coolant channel (the existing common structure) opened inside the engine 13, the heat generated by the operation of the engine 13 can be absorbed, thereby achieving the cooling treatment of the engine 13. At the same time, after the coolant after absorbing the heat finally flows back to the radiator 6 through the return pipe 9, the multiple metal heat dissipation pipes and heat sinks arranged inside the radiator 6 can cooperate to achieve the cooling of the coolant entering the radiator, thereby achieving the effect of continuous circulation of the coolant inside the radiator 6 to dissipate heat from the engine 13.

[0058] At the same time, when the engine 13 starts running, it will drive the cooling fan 11 to rotate and suck the external air into the right side of the partition 3 (such as Fig.11As the airflow continuously flows through the radiator 6, the heat generated by the radiator 6 in cooling the coolant is continuously taken away, thereby achieving the effect of the radiator 6 continuously cooling the coolant, and the filter screen (drawn but not marked in the figure) installed on the right side of the forklift body 1 is passed through. Figure 3 As can be seen in FIG. 1 , the gas entering the forklift body 1 can be filtered (e.g. Figure 3 In the direction shown), dust and other impurities in the air can be effectively reduced to prevent corrosion and damage to the internal components of the forklift body 1.

[0059] At the same time, the gas collected on the right side of the partition 3 (such as Fig.11 The air will eventually enter the lower part of the air collecting box 2 and the upper end of the plurality of sealing plates 43 (as shown in the direction shown in the figure) through the one-way air inlet pipe 5. Figure 7 The air is blown out through a plurality of exhaust ports 44 to dissipate heat from the lower ends of the engine 13, the electrical equipment 14 and the hydraulic equipment 15.

[0060] At the same time, blowing air from the bottom of the engine 13, electrical equipment 14 and hydraulic equipment 15 can effectively improve the effect of the equipment on the heat dissipation of the equipment. Since the free flow direction of hot air is upward, the gas blown upward from the bottom of the three can form a more direct convection heat exchange, which can better take away the heat generated by the equipment during operation, help to accelerate the transfer speed of the gas to the heat generated by the operation of the equipment, and improve the effect and speed of the equipment on the heat dissipation of the equipment.

[0061] Combined with Figure 6 and Figure 7 It can be seen that the engine 13, the electrical equipment 14 and the hydraulic equipment 15 are all provided with a plurality of exhaust ports 44 at the bottom, and they are all spaced a certain distance from the upper end of the air collecting box 2. Therefore, by cooperating with the corresponding plurality of exhaust ports 44, the engine 13, the electrical equipment 14 and the hydraulic equipment 15 can be respectively provided with uniform air blowing and heat dissipation at the bottom, which helps to further promote the air blowing and heat dissipation effect of the equipment on the plurality of them.

[0062] The cooling fan 11 inside the existing forklift body 1 usually directly blows air to dissipate heat at the front end of the engine 13, electrical equipment 14 and hydraulic equipment 15. However, due to the small spacing between the engine 13, electrical equipment 14 and hydraulic equipment 15, the complexity of their components, and the mutual shielding of some components, the flow of gas will be hindered, reducing the uniformity of the overall cooling of the cooling fan 11 to the several parts. Therefore, by blowing air to dissipate heat at the bottom of the several parts and cooperating with multiple exhaust ports 44, the effect of the equipment blowing air to dissipate heat to the several parts can be effectively improved.

[0063] At the same time, the gas collecting box 2 is made of a heat-insulating material, and specifically can be made of a material with good heat-insulating properties such as polyurethane foam. Figure 7As can be seen in the figure, the engine 13, the electrical equipment 14 and the hydraulic equipment 15 can be separated and placed by the air collecting box 2, so that the several equipments form a "concave" layout, so that the corresponding multiple exhaust ports 44 can respectively achieve the effect of accurate and concentrated blowing and cooling of the engine 13, the electrical equipment 14 and the hydraulic equipment 15, which helps to further improve the cooling effect of the equipment on the several equipments. At the same time, the air collecting box 2 itself has good thermal insulation performance, which can effectively reduce the heat transfer between the several equipments and the mutual flow of hot air between the several equipments (such as Figure 1 In the direction shown, the hot air at the upper end of the air collecting box 2 will eventually be discharged from the vents opened on the front and rear sides of the forklift body 1).

[0064] like Figure 1 , Figure 3 - Fig. 9 As shown, the pushing component includes a servo motor 45 fixedly installed in the forklift body 1, a threaded rod 46 is fixedly installed on the driving end of the servo motor 45, a push plate 48 is fixedly installed on the lower end of the sealing plate 43, a driving rod 49 is fixedly installed on the push plate 48, and a linearly evenly distributed sliding block 47 is threadedly installed on the threaded rod 46, and a limiting displacement groove 416 matching the corresponding driving rod 49 is opened on the sliding block 47.

[0065] The driving component includes a limiting cylinder 413 linearly and evenly fixedly installed at the lower end of the gas collecting box 2, a spiral groove 411 is opened on the round rod 410, and a limiting rod 414 matching the corresponding spiral groove 411 is passed through and fixedly installed on the limiting cylinder 413.

[0066] When the forklift body 1 starts to run, the servo motor 45 is started, and the servo motor 45 rotates alternately forward and reverse to drive the threaded rod 46 to drive the plurality of sliding blocks 47 to move back and forth (such as Figure 8 In the direction shown, during the reciprocating movement of the sliding block 47 to the left and right, the driving force applied to the corresponding driving rod 49 by the corresponding limiting groove 416 can drive the corresponding push plate 48 to drive the sealing plate 43 to move up and down, and when the multiple sealing plates 43 intermittently move upward, the gas between the sealing plate 43 and the gas collecting box 2 can be squeezed, so as to accelerate the speed of the gas being discharged from the corresponding multiple exhaust ports 44, and promote the effect of the corresponding multiple exhaust ports 44 to intermittently eject the pulse airflow, thereby improving the effect of the gas flow on further improving the cooling effect of the equipment on the engine 13, the electrical equipment 14 and the hydraulic equipment 15;

[0067] When the pulsed airflow is blown out from the multiple exhaust ports 44, its own higher flow rate can effectively increase the heat exchange rate of the gas to the surrounding hot air emitted from the engine 13, electrical equipment 14 and hydraulic equipment 15, thereby increasing the heat dissipation speed and effect of the equipment to the several.

[0068] When the sealing plate 43 intermittently drives the corresponding round rod 410 and the stirring member 412 to move upward together, the corresponding spiral groove 411 cooperates with the limit rod 414 to cause the round rod 410 to drive the corresponding stirring member 412 to rotate upward, and the plurality of stirring members 412 rotate upward (such as Figure 8 The gas at the upper end of the corresponding sealing plate 43 is disturbed, so that the gas at the lower end of the multiple sealing plates 43 and the gas collecting box 2 is sprayed toward the lower end of the engine 13, the electrical equipment 14 and the hydraulic equipment 15 in a turbulent state, which can help to further improve the effect of the equipment on the cooling of the above equipment;

[0069] The airflow blown out after being stirred by multiple agitators 412 can, to a certain extent, increase the intensity of the flow of this part of the airflow, which helps to increase the coordination of the corresponding exhaust ports 44, and respectively provide the intensity and effect of blowing and cooling the engine 13, electrical equipment 14 and hydraulic equipment 15, and by increasing the flow intensity of the ejected airflow, the uniformity of the blowing and cooling of several devices by the corresponding multiple exhaust ports 44 can be further improved to a certain extent.

[0070] When the round rod 410 is forced to move upward, the corresponding spiral groove 411 will exert an upward force on the corresponding limit rod 414, and this force can be specifically decomposed into a force perpendicular to the side wall of the spiral groove 411 and a force along the tangent direction of the spiral groove 411. The force perpendicular to the side wall of the spiral groove 411 can ensure that the limit rod 414 is in close contact with the spiral groove 411, and the force in the tangential direction will generate a torque that causes the round rod 410 to rotate, thereby achieving the effect of driving the round rod 410 to drive the corresponding stirring member 412 to rotate upward or rotate downward (such as Figure 8 direction shown).

[0071] At the same time, the one-way air intake pipe 5 and the multiple one-way exhaust pipes 41 can effectively prevent the sealing plate 43 from being forced to move downward (such as Figure 7 As shown in the direction, the hot air at the upper end of the air collecting box 2 is sucked into the interior of the air collecting box 2.

[0072] like Fig.10 - Fig.13 As shown, the air regulating assembly 7 includes a support tube 71 fixedly mounted on the partition 3, and two support tubes 71 are provided. The two support tubes 71 are fixedly connected with a one-way air supply pipe 72, and one end of the two one-way air supply pipes 72 are sealed and penetrated and fixedly mounted on the air collecting box 2, and a rotating rod 79 is rotatably mounted on the inner wall of the two support tubes 71, and a fan 710 is fixedly mounted on the two rotating rods 79, and a heat conduction box 73 is fixedly mounted on the electrical equipment 14 and the hydraulic equipment 15, and a trigger component is commonly installed between the two heat conduction boxes 73 and the two support tubes 71.

[0073] The trigger component includes storage cylinders 77 respectively fixedly mounted on the inner bottom walls of the two support tubes 71, and heat conduction plates 74 are fixedly mounted between the two heat conduction boxes 73 and the corresponding storage cylinders 77, and the two heat conduction plates 74 are both penetrated and fixedly mounted on the gas collecting box 2 and the partition plate 3, and the two heat conduction plates 74 are both sealed and penetrated and fixedly mounted on the corresponding support tubes 71;

[0074] A disc 78 is sealed and slidably installed in the two storage cylinders 77, and a rack 712 is fixedly installed on the two discs 78. A limiting groove 75 is provided on the two support tubes 71, and a moving block 76 is slidably installed on the two limiting grooves 75. The two moving blocks 76 are fixedly connected to the corresponding rack 712, and a rotating gear 711 meshing with the corresponding rack 712 is fixedly installed on the two rotating rods 79.

[0075] During the operation of the electrical equipment 14 and the hydraulic equipment 15, the heat generated will be transferred to the corresponding storage cylinder 77 (both storage cylinders 77 are made of heat-conducting materials) through the cooperation of the corresponding heat-conducting box 73 and the heat-conducting plate 74. If the temperature of the electrical equipment 14 or the hydraulic equipment 15 continues to rise to the critical temperature of vaporization of the volatile liquid stored in the corresponding storage cylinder 77, the volatile liquid stored in the corresponding storage cylinder 77 will quickly vaporize. At this time, according to the first law of thermodynamics, during the vaporization of the volatile liquid, the heat on the surface of the electrical equipment 14 or the hydraulic equipment 15 can be absorbed through the cooperation of the corresponding storage cylinder 77, the heat-conducting plate 74 and the heat-conducting box 73, thereby achieving the effect of timely heat dissipation of the electrical equipment 14 or the hydraulic equipment 15 (such as the continuous high-load operation of the forklift body 1, or the occurrence of failures in the coordinated operation of the internal components of the electrical equipment 14 and the hydraulic equipment 15, which are likely to cause the temperature of the electrical equipment 14 or the hydraulic equipment 15 to continue to rise).

[0076] The volatile liquid buffered inside the two storage cylinders 77 is acetone liquid. During the normal operation of the forklift body 1, the temperature of the components inside the electrical equipment 14 is usually below 70 degrees Celsius, while the temperature of the hydraulic equipment 15 is usually between 30 and 55 degrees Celsius. If the forklift body 1 is operated at a high load for a long time, the temperature of the electrical equipment 14 or the hydraulic equipment 15 will continue to rise to more than 70 degrees Celsius, and when it continues to rise, it is easy to reduce the stability of the continuous operation of the electrical equipment 14 or the hydraulic equipment 15. The boiling point of acetone is about 57 degrees Celsius. Although it is lower than 70 degrees Celsius, as the temperature continues to rise, it will quickly vaporize when the liquid temperature reaches about 70 degrees Celsius. Therefore, the use of acetone liquid as the volatile liquid can effectively ensure the timely heat dissipation of the electrical equipment 14 or the hydraulic equipment 15 when the temperature continues to rise.

[0077] At the same time, when the acetone liquid in the storage cylinder 77 absorbs heat and vaporizes, the gas in the storage cylinder 77 increases continuously, and this part of the gas generates an upward thrust on the corresponding disc 78, which causes the disc 78 to move upward continuously (such as Fig.11 As the disk 78 moves upward, the corresponding fan 710 can be driven to suck the gas collected on the right side of the partition 3 into the corresponding support pipe 71 (as shown in the figure) through the cooperation of the corresponding rack 712, the rotating gear 711 and the rotating rod 79. Fig.11 The air flows in the direction shown in the figure) and finally enters the lower part of the electrical equipment 14 or the hydraulic equipment 15 along the corresponding one-way air supply pipe 72. Thus, when the temperature of the electrical equipment 14 or the hydraulic equipment 15 continues to rise, the amount of air blown to the lower end of the side can be increased to further accelerate the cooling of the electrical equipment 14 or the hydraulic equipment 15, thereby ensuring the cooling effect of the equipment.

[0078] like Fig.13 - Fig.16 As shown, the flow regulating assembly 8 includes a conduit 81 fixedly connected to the radiator 6, and a liquid replenishing pipe (drawn but not marked in the figure, from Fig.13 As can be seen in the figure, a return liquid pipe 9 is fixedly connected between the radiator 6 and the engine 13, and the liquid replenishment pipe and the return liquid pipe 9 are both sealed and penetrated and fixedly installed on the partition 3, a temperature detector 10 is installed on the return liquid pipe 9, a speed regulating mechanism is installed on the conduit 81, and an infusion component is installed on the radiator 6.

[0079] The speed regulating mechanism includes a rubber sealing ring 82 fixedly installed in the conduit 81, and there are two rubber sealing rings 82. A plurality of spring telescopic rods 83 are fixedly installed in the conduit 81, and an adjustment plate 84 is fixedly installed between the two corresponding spring telescopic rods 83. An elastic pad 85 is fixedly installed between the two adjustment plates 84. There are two elastic pads 85, and the two adjustment plates 84 and the two elastic pads 85 are fixedly connected to the two rubber sealing rings 82. Pushing pieces 86 are fixedly installed on the two adjustment plates 84, and the two pushing pieces 86 are sealed and penetrated and slidably installed on the conduit 81. A force transmission component is installed between the conduit 81 and the radiator 6.

[0080] The force transmission component includes a support frame fixedly mounted on the radiator 6, on which a motor 87 is fixedly mounted, and a gear rod 88 is fixedly mounted on the driving end of the motor 87. An annular groove is provided on the radiator 6, and a parallel shaft gear 89 meshing with the gear rod 88 is rotatably mounted on the annular groove, and a connecting rod 810 is fixedly mounted on the parallel shaft gear 89. There are two connecting rods 810, and a turntable 811 is fixedly mounted between the two connecting rods 810. Two spring telescopic rods 812 evenly distributed in a ring shape are fixedly mounted on the turntable 811, and a driving plate 813 is fixedly mounted on the two spring telescopic rods 812.

[0081] If the temperature of the engine 13 itself continues to rise during the operation of the forklift body 1 (such as the forklift body 1 is operated at high load for a long time or there is a fault inside it), the temperature of the coolant flowing through the engine 13 will also continue to rise. When the temperature detector 10 detects (its specific working principle and internal components are common technologies in the prior art and are not further elaborated here), when the temperature of the coolant flowing back to the radiator 6 through the return pipe 9 exceeds the set value, the temperature detector 10 will send a signal to the motor 87 to drive the motor 87 to start running. During the operation of the motor 87, the gear rod 88, the parallel shaft gear 89 and the two connecting rods 810 can drive the turntable 811 to rotate clockwise at high speed with the guide tube 81 as the axis (such as Fig.15 The centrifugal force generated during the high-speed rotation of the turntable 811 will cause the multiple spring telescopic rods 812 to overcome their own elastic force and drive the corresponding drive plates 813 to expand outwards;

[0082] During the process of the multiple driving plates 813 rotating and expanding outward, a thrust is applied to the two pushers 86, so that the two pushers 86 drive the corresponding adjustment plates 84 to gradually move away from each other. During the process of the two adjustment plates 84 moving away from each other by stretching the two elastic pads 85, an extrusion force is applied to the two rubber sealing rings 82, thereby increasing the effective diameter of the conduit 81 for transporting coolant to the infusion tube, and increasing the circulation flow speed of the coolant inside the engine 13 (the operating power of the pump is set to a constant value. When the effective diameter of the infusion inside the conduit 81 increases, the speed of the radiator 6 transporting coolant to the inside of the engine 13 can be accelerated, just like drinking water with a straw. The thicker the straw, the more and faster the water can be sucked in under the same suction force), and the speed of its heat absorption effect is accelerated, thereby accelerating the heat dissipation of the engine 13 and ensuring the stability of the continuous operation of the engine 13.

[0083] At the same time, in order to ensure the pushing and limiting effect on the two pushers 86 during the unfolding and continuous rotation of the multiple drive plates 813, it is set that after the multiple drive plates 813 are unfolded, the distance between two adjacent drive plates 813 is smaller than the vertical length of the two pushers 86.

[0084] like Fig.13 - Fig.16 As shown, the infusion component includes a fixing frame 815 fixedly mounted on the radiator 6, an infusion hose 816 is fixedly connected between the radiator 6 and the right heat conduction box 73, and the infusion hose 816 is fixedly connected to the fixing frame 815, and a pipe body 12 is fixedly connected between the left heat conduction box 73 and the radiator 6 (the left and right here refer to Fig.13 , Fig.13The position of the heat conduction box 73 marked in the figure is on the right side, and the position of the tube body 12 marked in the figure is on the left side), and the tube body 12 and the infusion hose 816 are both passed through and fixedly installed on the gas collecting box 2 and the partition 3, and a connecting pipe 817 is fixedly connected between the two heat conduction boxes 73, and extrusion blocks 814 are fixedly installed on multiple driving plates 813.

[0085] When the temperature of the engine 13 itself continues to rise, the heat generated by the operation of the engine 13 is easily transferred to the electrical equipment 14 and the hydraulic equipment 15 through heat conduction, heat radiation, etc., causing the temperature of the electrical equipment 14 and the hydraulic equipment 15 to rise to a certain extent. Especially when the forklift body 1 is running at a high load and the temperature of the engine 13 continues to rise, the electrical equipment 14 needs to deliver a larger current and the hydraulic equipment 15 needs to provide a larger pressure to prompt the engine 13 to output a larger power to maintain the operation of the forklift body 1. Therefore, in this process, the temperature of the electrical equipment 14 and the hydraulic equipment 15 will also increase accordingly.

[0086] When the plurality of driving plates 813 are subjected to force with the conduit 81 as the axis, the corresponding extrusion blocks 814 are driven to expand outwards clockwise and rotate at high speed (such as Fig.15 The extrusion blocks 814 intermittently squeeze the infusion hose 816, and when the extrusion blocks 814 continue to rotate to release the squeezing of the corresponding part of the infusion hose 816, the negative pressure generated by the corresponding part of the infusion hose 816 can suck the coolant buffered inside the radiator 6 into the infusion hose 816. At this time, the multiple extrusion blocks 814 continue to rotate clockwise, which will push the coolant sucked into the infusion hose 816 forward clockwise, thereby achieving the effect of the infusion hose 816 extracting the coolant inside the radiator 6 (similar to the existing peristaltic pump pumping principle).

[0087] The coolant that enters the infusion hose 816 eventually enters the right heat conduction box 73. At this time, the coolant in the right heat conduction box 73 can further dissipate heat for the electrical equipment 14. At the same time, when the coolant in the right heat conduction box 73 is filled, the new coolant that enters the right heat conduction box 73 will enter the left heat conduction box 73 along the connecting pipe 817, thereby further dissipating heat for the hydraulic equipment 15 (such as Fig.13 The cooling liquid in the left heat conduction box 73 will eventually flow back to the inside of the radiator 6 along the tube body 12), thereby improving the cooling speed of the engine 13 while simultaneously improving the cooling effect of the electrical equipment 14 and the hydraulic equipment 15.

[0088] Usage: When the engine 13 cooperates with the electrical equipment 14 and the hydraulic equipment 15 to drive the forklift body 1 to operate, the existing liquid pump cooperates with the conduit 81, the liquid replenishing pipe and the liquid return pipe 9 to promote the coolant cached in the radiator 6 to circulate in the engine 13 to achieve heat dissipation. At the same time, when the engine 13 is running, it will drive the cooling fan 11 to rotate and suck the external gas into the right side of the partition 3 (such as Fig.11 The gas will flow along the one-way air inlet pipe 5 into the lower end of the gas collecting box 2 (as shown in the direction of FIG. Figure 7 In the direction shown), at this time, through the cooperation of the corresponding multiple exhaust ports 44 and the air collecting box 2, accurate and concentrated blowing and cooling of the lower ends of the engine 13, the electrical equipment 14 and the hydraulic equipment 15 can be achieved, thereby effectively improving the effect of the equipment on the cooling of the above-mentioned equipment.

[0089] At the same time, when the three are running, the servo motor 45 is started. During the operation of the servo motor 45, through the cooperation with the pushing component and the driving component, the corresponding multiple exhaust ports 44 can be prompted to intermittently spray pulsed airflow with a certain rotational force, thereby effectively improving the effect of the equipment on the heat dissipation of several devices.

[0090] If the electrical equipment 14 or the hydraulic equipment 15 continues to operate and its own temperature continues to rise, exceeding the critical temperature of vaporization of the corresponding volatile liquid, the volatile liquid cached in the corresponding storage tube 77 of the electrical equipment 14 or the hydraulic equipment 15 will continue to vaporize. During the vaporization process of the volatile liquid, the heat of the electrical equipment 14 or the hydraulic equipment 15 can be dissipated. When the gas inside the storage tube 77 gradually increases, the trigger component can be used to drive the corresponding fan 710 to rotate, and the gas on the right side of the partition 3 can be sucked into the lower end of the electrical equipment 14 or the hydraulic equipment 15, thereby increasing the amount of gas blown out from the bottom of the component, thereby further accelerating the heat dissipation speed of the electrical equipment 14 or the hydraulic equipment 15.

[0091] If the temperature of the engine 13 continues to rise and the temperature detector 10 detects that the temperature of the coolant returning from the return pipe 9 exceeds the set temperature, the temperature detector 10 transmits a signal to the motor 87 to drive the motor 87 to operate. At this time, the operation of the motor 87 will drive the two adjustment plates 84 away from each other through cooperation with the speed regulating mechanism. Therefore, the effective diameter of the coolant transported by the conduit 81 can be increased, the circulation flow speed of the coolant inside the engine 13 can be increased, and the heat exchange speed of the coolant to the engine 13 can be increased. In this process, through the cooperation of the motor 87 and the infusion component, the coolant can be transported to the inside of the two heat conduction boxes 73 through the cooperation of the infusion hose 816 and the connecting pipe 817, thereby achieving the effect of simultaneously improving the heat dissipation speed of the electrical equipment 14 and the hydraulic equipment 15.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
