Description

Technical Field

[0001] The present application relates to the technical field of paper straw production and processing, and in particular to an air-cooled and water-cooled dual-mode heat dissipation device for a diesel generator set. Background Art

[0002] A diesel generator set is a small power generation device that uses diesel as fuel and a diesel engine as the prime mover to drive a generator to generate electricity. Its working principle is that the diesel engine drives the generator, converting the diesel energy into electricity. Since the diesel engine generates a lot of heat during operation, it needs to be dissipated through a heat sink.

[0003] Existing diesel generator sets equipped with heat dissipation devices generally include a generator, a diesel engine and a water cooler. The diesel engine and the generator are connected in a transmission manner and a heat dissipation channel for passing liquid is provided inside the diesel engine casing. A water storage chamber, a refrigeration device and a water pump are provided inside the water cooler. The water inlet and the water outlet of the water storage chamber are respectively connected to the two ends of the heat dissipation channel through pipes to form a circulation loop between the heat dissipation channel and the water storage chamber. The refrigeration device can cool the water in the water storage chamber. The water pump is connected to the circulation loop and can drive the water in the circulation loop to circulate, so that the diesel engine can dissipate heat through the low-temperature water in the circulation loop.

[0004] However, since the water cooler can only dissipate heat for the diesel engine when the water pump is turned on, in order to prevent the diesel engine from being damaged due to overheating, the diesel generator set needs to turn on the water cooler immediately every time it is started, which can easily cause a waste of electrical energy resources.

[0005] In view of this, it is necessary to provide an air-cooled and water-cooled dual-mode heat dissipation device for a diesel generator set. Summary of the Invention

[0006] In order to solve the problem that the existing diesel generator set needs to turn on the water cooler immediately every time it is started, which easily causes waste of electric energy resources, the present application provides an air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set.

[0007] The present application provides an air-cooled and water-cooled dual-mode heat dissipation device for a diesel generator set, which adopts the following technical solution: comprising a frame, a generator, a diesel engine, a cooling assembly, and a control assembly, wherein the generator and the diesel engine are both arranged on the frame, and the diesel engine is drivingly connected to the input shaft of the generator; The cooling assembly is capable of dissipating heat from the diesel engine; The control component is arranged on the diesel engine, and when the temperature of the diesel engine exceeds the rated heat dissipation temperature, the control component can control the cooling component to open and dissipate heat for the diesel engine.

[0008] By adopting the above technical solution, after starting the diesel generator set, the control component will control the cooling component to start and dissipate heat for the diesel engine when the temperature of the diesel engine exceeds the rated heat dissipation temperature, so that the user can determine the start-up time of the cooling component through the control component, without having to turn on the cooling component immediately every time the diesel generator set is started. This ensures that when the cooling component does not need to be turned on, such as when the diesel generator set is only running for a short time or the ambient temperature is low and can meet the heat dissipation needs of the diesel engine, the air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set will not consume electrical energy resources to dissipate heat for the diesel generator set, so that the air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set has good energy-saving capabilities.

[0009] Specifically, the cooling assembly includes a liquid storage tank, a circulating pump and a refrigeration device. A cooling through-hole is opened on the diesel engine. One end of the cooling through-hole is connected to the liquid outlet of the liquid storage tank through a pipe, and the other end of the cooling through-hole is connected to the liquid inlet of the liquid storage tank through a pipe to form a circulating liquid path between the cooling through-hole and the liquid storage tank. The circulating pump is connected to the circulating liquid path and can drive the liquid in the circulating liquid path to circulate. The refrigeration device is arranged on the liquid storage tank and can cool the liquid in the liquid storage tank.

[0010] By adopting the above technical solution, the refrigeration device can cool the liquid in the liquid storage tank, and the circulating pump can drive the liquid in the liquid storage tank to circulate along the circulating liquid circuit after being started, so that the liquid in the circulating liquid circuit can take away the heat generated by the diesel engine when it is working, thereby enabling the cooling component to dissipate heat from the diesel engine.

[0011] Furthermore, the control component includes a flip tank, a flip plate and two piston rods, a flip shaft is provided in the middle of the side wall of the flip tank and is rotatably connected to the top of the diesel engine via the flip shaft, a pair of electrical terminals are provided on the top of the diesel engine, one of the two electrical terminals is electrically connected to the positive pole of the circuit of the cooling component, and the other of the two electrical terminals is electrically connected to the negative pole of the circuit of the cooling component, the interior of the flip tank is symmetrically formed with the flip shaft as the center, two accommodating cavities are provided in each of the accommodating cavities, a pair of conductive terminals are provided in each of the accommodating cavities, one end of each conductive terminal extends to the outside through a through hole provided on the flip tank, the two conductive terminals in each of the accommodating cavities correspond to the two electrical terminals one by one, one of the two accommodating cavities away from the diesel engine is filled with a conductive medium and forms a far heat cavity, and one of the two accommodating cavities close to the diesel engine is filled with an insulating medium and forms a near heat cavity, the conductive terminals in the near heat cavity abut against the corresponding electrical terminals; A connecting hole is provided between the two accommodating cavities to connect the two, a flip plate shaft is provided in the middle of the flap and is rotatably connected to the inner wall of the connecting hole via the flip plate shaft, and two accommodating holes leading to the outside are relatively opened on the hole wall of the connecting hole with the flap as the center, the length direction of each accommodating hole is perpendicular to the length direction of the flip plate shaft, and the accommodating holes correspond to the piston rods one by one, the piston end of each piston rod is inserted into the corresponding accommodating hole, and the piston of each piston rod abuts against the hole wall of the corresponding accommodating hole and can slide along the accommodating hole, and an abutment is provided on the rod body of each piston rod close to the flap, and when the two abutments are located on the same side of the flip shaft, the flap is abutted between the two abutments and can block the connecting hole; When the insulating medium in the near-heat-pressure cavity expands due to heat and drives the piston rod in the near-heat-pressure cavity away from the flap, so that the two abutment members are located on different sides of the flap axis, the flap can rotate around the flap axis and connect the connecting hole with the two accommodating cavities, so that the conductive medium enters the near-heat-pressure cavity and the two power terminals are electrically connected via the two conductive terminals on the near-heat-pressure cavity and the conductive medium.

[0012] By adopting the above technical solution, before starting the diesel generator set, the user can pre-fill a conductive medium such as an aqueous solution into one accommodating chamber and an insulating medium such as air into the other accommodating chamber. At this time, the conductive medium will fall into the accommodating chamber located below under the action of its own weight, and then the two abutments are driven to be located on the same side of the flap shaft by pressing the two piston rods, so that the flap is abutted between the two abutments and can block the connecting hole, and then the flip tank is adjusted so that the accommodating chamber filled with the conductive medium is away from the diesel engine and forms a far-heat chamber, and the accommodating chamber filled with the insulating medium is close to the diesel engine and forms a near-heat chamber, and the conductive terminal on the near-heat chamber is electrically connected to the power terminal. Position, then start the diesel generator set to start generating electricity. As the temperature of the diesel engine surface continues to rise, the insulating medium in the near-heat cavity will expand due to the heat and drive the piston rod in the near-heat cavity away from the flap. When the temperature of the diesel engine exceeds the rated heat dissipation temperature, the two abutments will be located on different sides of the flap axis, so that the flap can rotate around the flap axis and connect the connecting hole with the two accommodating cavities, and the conductive medium in the far-heat cavity will fall into the near-heat cavity under the action of its own weight, so that the two power terminals are electrically connected via the two conductive terminals on the near-heat cavity and the conductive medium, so that the positive and negative poles of the circuit of the cooling component are electrically connected to form a loop, and then the cooling component starts to start cooling.

[0013] Furthermore, an inclined surface is formed on the surface of the flap, one side of the inclined surface is located near the flap axis, and the other side of the inclined surface extends toward the direction close to the accommodating hole, and the inclined surface is inclined toward the direction close to the near-heat cavity in the direction away from the accommodating hole.

[0014] By adopting the above technical solution, the setting of the inclined surface enables the abutment to apply a force to the side of the flap close to the accommodating hole on the flap to rotate in the direction close to the far heat cavity when sliding along the inclined surface, thereby causing the flap to rotate and the connecting hole to connect the two accommodating cavities.

[0015] Furthermore, the abutment member is a roller, and the wheel surface of the roller abuts against the plate surface of the flap.

[0016] By adopting the above technical solution, the setting of the roller can reduce the friction between the abutment and the flap, making it easier for the pressure after the insulating medium expands due to heat to drive the piston rod to drive the abutment to move.

[0017] Furthermore, it also includes a flip motor, which is connected to the flip shaft and can drive the flip shaft to drive the flip tank to rotate.

[0020] By adopting the above technical solution, the controller can first control the two electromagnets to turn on to drive the corresponding magnetic parts to move toward the direction close to the flip plate, and then make the two abutment parts located on the same side of the flip plate shaft, and the flip plate is abutted between the two abutment parts and can block the connecting hole, and then control the flip motor to drive the flip shaft to drive the flip tank to rotate, so as to realize automatic reset of the control component.

[0021] Furthermore, the cooling assembly also includes an air-cooling fan. A ventilation hole is opened on the casing of the generator. The air-cooling fan is arranged in the ventilation hole, and the rotating shaft of the air-cooling fan is connected to the input shaft of the generator.

[0022] By adopting the above technical solution, the generator can drive the air-cooling fan to rotate when generating electricity, and then the generator is cooled by the air-cooling fan.

[0023] Furthermore, a dust screen is provided in the ventilation hole.

[0024] By adopting the above technical solution, the dust screen can block the external dust, so that the external dust is not easily blown into the generator by the air cooling fan.

[0025] Specifically, movable wheels are provided at the bottom of the frame.

[0026] By adopting the above technical solution, the provision of the moving wheels can facilitate the user to move the air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set.

This ensures that when the cooling assembly does not need to be turned on, such as when the diesel generator set is only operated for a short time or the ambient temperature is low and can meet the heat dissipation demand of the diesel engine, the air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set does not consume electric energy resources to dissipate heat for the diesel generator set, so that the air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set has good energy-saving capabilities; 2.

[0031] See also Figure 2 and Figure 3The liquid storage tank 41 stores liquid refrigerant such as water, cooling oil, etc. A cooling through-hole is provided on the diesel engine 3. One end of the cooling through-hole is connected to the liquid outlet of the liquid storage tank 41 through a pipe, and the other end of the cooling through-hole is connected to the liquid inlet of the liquid storage tank 41 through a pipe and forms a circulating liquid path between the cooling through-hole and the liquid storage tank 41. The circulating pump 42 is connected to the circulating liquid path and can drive the liquid in the circulating liquid path to circulate. The refrigeration device 43 is provided on the liquid storage tank 41. The refrigeration device 43 can be a semiconductor refrigeration, and the circulating pump 42 can drive the liquid in the liquid storage tank 41 to circulate along the circulating liquid path after starting, so that the liquid in the circulating liquid path can take away the heat generated when the diesel engine 3 is working, so that the cooling component 4 can dissipate heat from the diesel engine 3.

[0032] See also Figure 2 and Figure 3 The control assembly 5 includes a flip tank 51, a flap 52 and two piston rods 53. A flip shaft is provided in the middle of the side wall of the flip tank 51. A pair of bearing seats are provided on the top of the diesel engine 3 with the flip tank 51 as the center, and both ends of the flip shaft are transmission-connected with an adjacent bearing seat. A tightening bolt 12 is also screwed on one of the bearing seats. The screw end of the tightening bolt 12 can abut against the flip shaft and limit the rotation of the flip shaft in the bearing seat. A pair of electrical terminals 31 are provided on the top of the diesel engine 3. One of the two electrical terminals 31 is connected to the The positive pole of the circuit of the circulation pump 42 is electrically connected through a power line 44, and the other of the two power terminals 31 is electrically connected to the negative pole of the circuit of the circulation pump 42 through a power line 44. The interior of the flip tank 51 is symmetrically formed with the flip axis as the center to form two accommodating cavities, each of which is provided with a pair of conductive terminals 513. One end of each conductive terminal 513 extends to the outside through a through hole provided on the flip tank 51. The two conductive terminals 513 in each accommodating cavity correspond to the two power terminals 31 one by one, and the two accommodating cavities are remote. The one away from the diesel engine 3 is filled with a conductive medium and forms a far heat chamber 512. The one of the two accommodating chambers closer to the diesel engine 3 is filled with an insulating medium and forms a near heat chamber 511. The conductive terminal 513 in the near heat chamber 511 abuts against the corresponding power terminal 31. A connecting hole is provided between the two accommodating chambers to connect the two. A flip plate 52 shaft is provided in the middle of the flap 52 and is rotatably connected to the inner wall of the connecting hole via the flap 52 shaft. Two accommodating holes leading to the outside are opened on the wall of the connecting hole with the flap 52 as the center. The length direction of each accommodating hole is perpendicular to the length direction of the axis of the flap 52. The accommodating holes correspond to the piston rods 53 one by one. The piston end of each piston rod 53 is inserted into the corresponding accommodating hole, and the piston of each piston rod 53 abuts against the hole wall of the corresponding accommodating hole and can slide along the accommodating hole. An abutment 531 is provided on the side of the rod body of each piston rod 53 close to the flap 52. When the two abutment 531 are located on the same side of the axis of the flap 52, the flap 52 is abutted between the two abutment 531 and can block the connecting hole.

[0033] Specifically, the conductive medium may be an aqueous solution, and the insulating medium may be a substance such as air, which has a lower density than the conductive medium and does not dissolve with the conductive medium; inclined surfaces 522 are formed on both side surfaces of the flap 52, one side of the inclined surface 522 is located near the axis of the flap 52, and the other side of the inclined surface 522 extends in the direction close to the receiving hole, and the inclined surface 522 is inclined in the direction away from the receiving hole and close to the near heat cavity 511, so that when the abutment 531 slides along the inclined surface 522, it will apply a force to the side of the flap 52 close to the receiving hole on the flap 52 to rotate in the direction close to the far heat cavity 512, thereby causing the flap 52 to rotate and connecting the connecting hole to the two receiving cavities; the abutment 531 The roller can be abutted against the surface of the flap 52 to reduce the friction between the abutment 531 and the flap 52, making it convenient for the pressure after the insulating medium expands due to heat to drive the piston rod 53 to drive the abutment 531 to move; a pressing rod 533 can also be provided on the piston end of the two piston rods 53, and one end of each pressing rod 533 extends out of the flip tank 51 through the accommodating hole, and an abutting protrusion 515 that can abut against the side of the piston facing away from the flap 52 is provided on the hole wall of each accommodating hole away from the flap 52, so that the user can adjust the piston rod 53 by moving the pressing rod 533, and the abutting protrusion 515 can prevent the piston rod 53 from being ejected from the accommodating hole by the expanded insulating medium.

[0034] The implementation principle of the air-cooled and water-cooled dual-mode heat dissipation device for a diesel generator set in this application is as follows: The two abutments 531 are located on different sides of the axis of the flap 52, so that the flap 52 can rotate around the axis of the flap 52 and connect the two accommodating chambers, and the conductive medium will fall into the near-heat chamber 511 under the action of its own weight. Then, the previously pulled pressing rod 533 is pulled back to make the two abutments 531 located on the same side of the axis of the flap 52, so that the flap 52 is abutted between the two abutments 531 and can block the connecting hole. Then, the flip tank 51 is adjusted so that the accommodating chamber filled with the conductive medium is away from the diesel engine 3 and forms the far-heat chamber 512, and the accommodating chamber filled with the insulating medium is close to the diesel engine 3 and forms the near-heat chamber 511, and the conductive medium on the near-heat chamber 511 is When the temperature of the diesel engine 3 rises, the insulating medium in the near heat cavity 511 will expand due to the heat and drive the piston rod 53 in the near heat cavity 511 away from the flap 52. When the temperature of the diesel engine 3 exceeds the rated heat dissipation temperature, the two abutting members 531 will be located on different sides of the flap 52 axis, so that the flap 52 can rotate around the flap 52 axis and connect the two accommodating cavities with the connecting hole, and the conductive medium in the far heat cavity 512 will fall into the near heat cavity 511 under the action of its own weight, so that the two power terminals 31 are electrically connected via the two conductive terminals 513 on the near heat cavity 511 and the conductive medium, so that the positive and negative poles of the circuit of the cooling component 4 are electrically connected to form a loop, and then the cooling component 4 starts to cool. When the diesel generator set 2 stops for a period of time and needs to be started again, the user can first toggle the pressing rod 533 of the near-heat chamber 511 to make the two abutting parts 531 located on the same side of the axis of the flap 52, and then make the flap 52 abut between the two abutting parts 531 and be able to block the connecting hole, and then loosen the tightening bolt 12 and turn the flip tank 51 up and down to make the accommodating cavity filled with the conductive medium away from the diesel engine 3 and form the far-heat chamber 512, and the accommodating cavity filled with the insulating medium close to the diesel engine 3 and form the near-heat chamber 511, and the conductive terminal 513 on the near-heat chamber 511 is electrically connected to the power terminal 31, and then tighten the screw 12. Tighten the bolt 12 and finally start the diesel generator set 2 to start generating electricity, so that the user can determine the opening time of the cooling component 4 through the control component 5, without having to immediately open the cooling component 4 every time the diesel generator set 2 is started, thereby ensuring that when the cooling component 4 does not need to be opened, such as when the diesel generator set 2 is only running for a short time or the ambient temperature is low and can meet the heat dissipation demand of the diesel engine 3, the air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set will not consume electric energy resources to dissipate heat for the diesel generator set 2, so that the air-cooled and water-cooled dual-mode heat dissipation device for the diesel generator set has good energy-saving capabilities.

[0035] It should be noted that the rated heat dissipation temperature can be artificially adjusted by controlling the thermal expansion ratio of the insulating medium and the friction force to which the piston rod 53 is subjected when moving.

[0036] See also Figure 4 and Figure 5 In a second embodiment, a dual-mode heat dissipation device for air and water cooling of a diesel generator set further includes a flip motor 6 and a controller (not shown). The flip motor 6 is connected to a flip shaft and can drive the flip shaft to rotate the flip tank 51. An electromagnet 514 is provided on the side of each abutting protrusion 515 near the flap 52. A magnetic member 532 is provided on the piston end of each piston rod 53. The magnetic member 532 can be a magnet. Each electromagnet 514 and the flip motor 6 are electrically connected to the controller. The controller can control the electromagnet 514 to turn on and apply a repulsive force to the corresponding magnetic member 532. The controller can first control the two electromagnets 514 to turn on to drive the corresponding magnetic member 532 to move toward the flap 52, thereby causing the two abutting members 531 to be located on the same side of the flap 52 axis. The flap 52 is abutted between the two abutting members 531 and can block the communication hole. The flip motor 6 is then controlled to drive the flip shaft to rotate the flip tank 51, thereby achieving automatic resetting of the control assembly 5.
