Abstract
Description
Technical Field
[0001] This utility model relates to the field of diesel generator set heat dissipation. More specifically, this utility model relates to a diesel generator set radiator that is highly efficient in heat dissipation and easy to clean. Background Technology
[0002] The radiator plays a crucial role in the operation of a diesel generator set. Traditional diesel generator set radiators suffer from several problems, the first being unsatisfactory heat dissipation efficiency. Common cooling methods are often simple air or water cooling, which cannot effectively dissipate heat during prolonged high-load operation. This is because their heat dissipation structure design is not optimal; for example, the heat exchange area is limited, and the flow path and speed of air or coolant are not optimized, leading to heat accumulation, affecting the normal operation of the generator set, and reducing its stability and service life.
[0003] Secondly, cleaning and maintenance are quite difficult. In actual use environments, radiators accumulate a large amount of dust, impurities, and other contaminants. Existing radiator filtration structures are simple and ineffective at blocking fine particles, allowing dust to easily enter the cooling system. Furthermore, when cleaning is required, the disassembly and installation process is cumbersome, consuming significant manpower and time.
[0004] Furthermore, traditional radiators suffer from poor coordination among their components. The heat dissipation module, airflow structure, and filter assembly operate independently, lacking an efficient collaborative mechanism. This prevents them from fully utilizing their overall heat dissipation and cleaning functions, further reducing radiator performance. Addressing these issues presents significant technical challenges and increased costs due to the optimization of multiple components and the matching and coordination between them. Utility Model Content
[0005] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.
[0006] To achieve these objectives and other advantages according to the present invention, a diesel generator set radiator that is highly efficient in heat dissipation and easy to clean is provided, comprising:
[0007] The shell has a liquid distribution manifold at the top and a liquid collection manifold at the bottom;
[0008] A filter assembly is disposed on the air inlet side of the housing. The filter assembly includes a pre-diffusion grille, a stainless steel fine filter, a polyester fiber mesh, and multiple V-shaped guide ribs disposed between the stainless steel fine filter and the polyester fiber mesh, which are detachably disposed from the outside to the inside.

[0009] Multiple heat pipe heat dissipation modules are spaced apart inside the housing and located on the leeward side of the filter assembly. Each heat pipe heat dissipation module includes an independent heat pipe evaporation section and is connected to the liquid distribution manifold. The outlet of each heat pipe heat dissipation module flows into the liquid distribution manifold. The liquid distribution manifold is equipped with a circulation pump. Each branch pipe on the liquid distribution manifold is equipped with a branch valve.
[0010] An air guide shroud is disposed on the air outlet side of the housing, and a fan is disposed on the air outlet end of the air guide shroud;
[0011] Multiple sets of V-shaped air guide plates are disposed between two adjacent heat pipe heat dissipation modules and between the heat pipe heat dissipation module on the air inlet side and the polyester fiber mesh. The upper surface of the V-shaped air guide plate is provided with sinusoidal ripples arranged along its length, with a wavelength of 5~8mm and a wave height of 1~2mm. Multiple gradient honeycomb holes are opened on the end of the V-shaped air guide plate away from the air inlet side. The diameter of the honeycomb holes is 3~5mm and the opening rate is 10%~15%. The angle between the V-shaped air guide plate and the heat dissipation fins of the heat pipe heat dissipation module is 75~80°.
[0012] Preferably, a superconducting thermal grease layer is coated at the interface between the liquid distribution manifold and the heat pipe heat dissipation module.
[0013] Preferably, the V-shaped deflector is configured with a gradually changing V-angle, from 30° at the air inlet side to 50° at the end.
[0014] Preferably, the inlet end of the air guide shroud is provided with a front air guide grille at the front end of the fan, with an inclination angle of 20° and a spacing of 15mm.
[0015] Preferably, the outlet end of the air guide shroud is provided with a diffuser-type airflow guide tail fin with an expansion angle of 7°.
[0016] Preferably, the pre-diffusion grid has a pore size of 3 mm and the guide strips are set at 45°.
[0017] Preferably, the stainless steel fine filter is configured to taper from 0.8mm at the air inlet to 0.5mm at the end.
[0018] Preferably, the polyester fiber web is configured as a three-layer gradient meltblown structure with pore sizes of 8μm, 5μm, and 3μm from the air inlet side to the end.
[0019] Preferably, a return air duct is provided at the bottom of the housing, and the other end of the return air duct is connected to the leeward side of the stainless steel fine filter screen. The return air duct is equipped with a return air fan.
[0020] Preferably, the filtering component includes:
[0021] The frame has a pair of annular grooves on its inner sidewall and a pair of slots on its top that correspond to and communicate with the pair of grooves. The stainless steel fine filter screen and the polyester fiber screen are respectively sealed through the pair of slots and sealed and fixed in the pair of grooves. The V-shaped guide ribs are connected by multiple connecting rods and connected to the inner side of the frame.
[0022] A cover plate, the sealing cap of which is provided on a pair of grooves;
[0023] A pair of knobs are located on the top of the frame, and the knobs are rotated to tighten or loosen the cover plate.
[0024] This utility model has at least the following beneficial effects:
[0025] First, by setting up multi-layer filter components, it can effectively filter impurities in the air, and the detachable design makes it easy to clean and replace; the heat pipe heat dissipation module is independent and works with the liquid distribution manifold and the liquid collection pipe to improve heat dissipation efficiency; the air guide shroud and fan optimize airflow, and V-shaped guide plates are set between the heat pipe heat dissipation modules to avoid airflow short circuits. At the same time, the staggered layout of the wave-shaped heat dissipation fins of the heat pipe heat dissipation module enhances the turbulence effect and the heat exchange effect. Overall, it achieves efficient heat dissipation and is easy to clean and maintain, improving the operating stability and service life of the diesel generator set.
[0026] Secondly, by setting the V-shaped guide plate to a gradual V-angle, from 30° on the air inlet side to 50° at the end, the small angle at the inlet accelerates the airflow to penetrate the front section of the heat sink, while the large angle at the end guides the airflow to evenly cover the rear section, so that the airflow can fully contact the heat pipe heat dissipation module on both the air inlet side and the end, thereby enhancing the heat exchange effect and improving the heat dissipation efficiency.
[0027] Third, a front-mounted airflow guide grille is installed at the inlet end of the air shroud, located at the front of the fan, with an inclination angle of 20° and a spacing of 15mm. This front-mounted airflow guide grille pre-rectifies the airflow and filters large-scale turbulence, allowing the airflow to enter the fan more smoothly, reducing airflow disturbance, improving fan efficiency, and thus enhancing the overall cooling effect of the cooling system. During installation, it is securely connected to the outlet end of the air shroud. When the hot air exhausted by the fan passes through the diffuser-type airflow guide tail fin, the airflow will quickly diffuse due to the expansion angle, reducing airflow accumulation at the outlet and avoiding the formation of local turbulence. This allows hot air to be discharged more smoothly, improving the overall cooling performance of the cooling system.
[0028] Fourth, multiple silicone vibrating strips are spaced apart on the polyester fiber mesh to help shake off dust during cleaning.
[0029] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0041] like Figures 1-8 As shown, this utility model provides a diesel generator set radiator that is highly efficient in heat dissipation and easy to clean, comprising:
[0042] The housing 100 has a liquid distribution manifold 11 at the top and a liquid collection pipe at the bottom;
[0043] The filter assembly 200 is disposed on the air inlet side of the housing 100. The filter assembly 200 includes a pre-diffusion grille 21, a stainless steel fine filter screen 22, a polyester fiber mesh 23, and a plurality of V-shaped guide ribs 24 disposed between the stainless steel fine filter screen 22 and the polyester fiber mesh 23, and a plurality of silicone vibrating strips 25 are disposed at intervals on the polyester fiber mesh 23.
[0044] Multiple heat pipe heat dissipation modules 300 are spaced apart within the housing 100 and located on the leeward side of the filter assembly 200. Each heat pipe heat dissipation module 300 includes an independent heat pipe 31 evaporation section and is connected to the liquid distribution manifold 11. The outlet of each heat pipe heat dissipation module 300 flows into the liquid distribution manifold. The liquid distribution manifold is equipped with a circulation pump. Each branch pipe on the liquid distribution manifold 11 is equipped with a branch valve.
[0045] An air guide shroud 400 is disposed on the air outlet side of the housing 100, and a fan 41 is disposed on the air outlet end of the air guide shroud 400;
[0046] Multiple sets of V-shaped air guide plates 32 are disposed between two adjacent heat pipe heat dissipation modules 300 and between the heat pipe heat dissipation module 300 on the air inlet side and the polyester fiber mesh 23. The upper surface of the V-shaped air guide plate 32 is provided with sinusoidal waves 33 arranged along its length, with a wavelength of 5~8mm and a wave height of 1~2mm. Multiple gradient honeycomb holes 34 are opened on the end of the V-shaped air guide plate 32 away from the air inlet side. The diameter of the honeycomb holes is 3~5mm and the opening rate is 10%~15%. The angle between the V-shaped air guide plate 32 and the heat sink 35 of the heat pipe heat dissipation module 300 is 75~80°.
[0047] In the above technical solution, by setting up a multi-layer filter assembly 200, impurities in the air can be effectively filtered, and the detachable design facilitates cleaning and replacement; the heat pipe heat dissipation module 300 is independent and works in conjunction with the liquid distribution manifold 11 and the liquid collection pipe to improve heat dissipation efficiency; the air guide shroud 400 and the fan 41 optimize airflow, and a V-shaped guide plate 32 is set between the heat pipe heat dissipation modules 300 to avoid airflow short circuit. At the same time, the staggered layout of the wave-shaped heat dissipation fins 35 of the heat pipe heat dissipation module 300 enhances the turbulence effect and the heat exchange effect. Overall, it achieves efficient heat dissipation and is easy to clean and maintain, thereby improving the operational stability and service life of the diesel generator set 500.
[0048] Specifically, firstly, a distribution manifold 11 is installed at the top of the housing 100, and a collection pipe is installed at the bottom. The distribution manifold 11 is used to evenly distribute the coolant to each heat pipe heat dissipation module 300, and the collection pipe is used to collect the coolant flowing out of the heat pipe heat dissipation module 300. The inlet end of the distribution manifold is connected to the coolant outlet of the cooling system of the diesel generator set 500.
[0049] A filter assembly 200 is installed on the air inlet side of the housing 100. A pre-diffuser grille 21 is installed on the outermost side, followed by a stainless steel fine filter 22. Multiple V-shaped guide ribs 24 are installed between the stainless steel fine filter 22 and the polyester fiber mesh 23. These V-shaped guide ribs 24 can change the airflow direction and enhance airflow turbulence. Then, the polyester fiber mesh 23 is installed. Multiple silicone vibrating strips 25 are spaced apart on the polyester fiber mesh 23 to assist in shaking off dust during cleaning.
[0050] Multiple heat pipe cooling modules 300 are installed at intervals on the leeward side of the filter assembly 200 within the housing 100. Each heat pipe cooling module 300 includes an independent heat pipe evaporation section, which is connected to the distribution manifold 11, and its outlet flows into the collection pipe. A return pipe is provided on the collection pipe, and a circulation pump is installed to drive the coolant circulation. The return pipe is connected to the coolant inlet of the cooling system of the diesel generator set 500. Each branch pipe on the distribution manifold 11 is equipped with a branch valve, which can adjust the coolant flow rate of each heat pipe cooling module 300 as needed.
[0051] An air guide shroud 400 is installed on the air outlet side of the housing 100, and a fan 41 is installed at the air outlet end of the air guide shroud 400. The air guide shroud 400 is used to connect to the exhaust duct 600.
[0052] Multiple sets of V-shaped baffles 32 are installed between two adjacent heat pipe cooling modules 300 and between the heat pipe cooling module 300 on the air inlet side and the polyester fiber mesh 23. The upper surface of the V-shaped baffles 32 is provided with sinusoidal ripples 33 arranged along its length, with a wavelength of 5-8 mm and a wave height of 1-2 mm. These ripples induce secondary eddies, reducing the boundary layer thickness and improving the heat transfer coefficient (experiments show an increase in heat dissipation efficiency of 5%-8%). Multiple gradient honeycomb holes 34 are formed on the ends of the V-shaped baffles 32 away from the air inlet side. The diameter of the honeycomb holes is 3-5 mm, and the opening ratio is 10%-15%, further balancing the airflow pressure distribution and reducing energy loss in the wake vortex region. The angle between the V-shaped baffles 32 and the heat sink 35 of the heat pipe cooling module 300 is 75-80° to avoid the "slip effect" caused by the airflow direction being parallel to the heat sink 35, thus enhancing the heat exchange effect.
[0053] Working principle: Air enters from the intake side, undergoes initial diffusion and filtration through the pre-diffusion grille 21, and then further filtration through the stainless steel fine filter 22 and polyester fiber mesh 23. Silicone vibrating strips 25 assist in cleaning. The filtered air is guided by the V-shaped guide plate 32, changing its direction and flow rate, and comes into full contact with the heat sink 35 of the heat pipe cooling module 300 for heat exchange. The coolant circulates in the heat pipe cooling module 300, the distribution manifold 11, and the collection pipe, carrying away heat. The fan 41 exhausts the hot air through the air guide shroud 400, completing the heat dissipation process.
[0054] Furthermore, a superconducting thermal grease layer is coated at the interface between the liquid distribution manifold 11 and the heat pipe heat dissipation module 300 to ensure that the thermal resistance of the contact surface is less than 0.05℃·cm² / W, thereby reducing thermal resistance, improving heat transfer efficiency, and enabling the heat pipe heat dissipation module 300 to transfer heat more quickly, further enhancing the heat dissipation performance of the entire radiator.
[0055] Specifically, when installing the manifold 11 and the heat pipe cooling module 300, a layer of superconducting thermal grease is evenly applied to the interface. Before application, the interface must be thoroughly cleaned to ensure it is free of impurities and oil. Then, using a special tool, the superconducting thermal grease is evenly applied to the interface surface, with the thickness controlled within a suitable range, generally 0.1~0.3mm. After application, the manifold 11 and the heat pipe cooling module 300 are connected and fixed, ensuring a tight fit. The superconducting thermal grease fills the tiny gaps at the interface, reducing thermal resistance and improving heat transfer efficiency, allowing the heat pipe cooling module 300 to transfer heat to the coolant more quickly, thereby improving the overall heat dissipation performance of the radiator.
[0056] Furthermore, the V-shaped guide plate 32 is configured with a gradually changing V-angle, from 30° at the air inlet side to 50° at the end. The small inlet angle accelerates the airflow through the front section of the heat sink 35, while the large end angle guides the airflow to evenly cover the rear section, ensuring that the airflow can fully contact the heat pipe cooling module 300 on both the air inlet side and the end, thereby enhancing the heat exchange effect and improving the heat dissipation efficiency.
[0057] Furthermore, a front guide grille 43 is provided at the inlet end of the air guide shroud 400, located at the front end of the fan 41, with an inclination angle of 20° and a spacing of 15mm. The front guide grille 43 can pre-rectify the airflow and filter large-scale turbulence, allowing the airflow to enter the fan 41 more smoothly, reducing airflow turbulence, improving the working efficiency of the fan 41, and thus improving the heat dissipation effect of the entire heat dissipation system. During installation, it is firmly connected to the outlet end of the air guide shroud 400. When the hot air exhausted by the fan 41 passes through the diffuser-type guide tail fin 42, the airflow will quickly diffuse due to the expansion angle, reducing the accumulation of airflow at the outlet and avoiding the formation of local turbulence. This allows the hot air to be exhausted more smoothly, improving the overall heat dissipation performance of the heat dissipation system.
[0058] Furthermore, the outlet end of the air guide shroud 400 is provided with a diffuser-type guide tail 42 with an expansion angle of 7°. This reduces the dynamic pressure loss at the outlet, improves the overall airflow utilization rate, and enhances the overall heat dissipation performance of the cooling system. During installation, it is securely connected to the outlet end of the air guide shroud 400. When the hot air exhausted by the fan 41 passes through the diffuser-type guide tail 42, the airflow will rapidly diffuse due to the expansion angle, reducing airflow accumulation at the outlet and avoiding the formation of local turbulence. This allows the hot air to be discharged more smoothly, improving the overall heat dissipation performance of the cooling system.
[0059] Furthermore, the pre-diffusion grille 21 has a pore size of 3mm, and the guide strip 26 is set at 45°. This guides large particles to the edge collection area of the filter, reducing impact on the core filtration area (experiments have shown a 22% increase in interception rate). During installation, the pre-diffusion grille 21 is fixed to the outermost layer on the air inlet side of the housing 100. The pre-diffusion grille 21 can initially filter larger particulate impurities in the air, such as insects. The 45° guide strip 26 ensures uniform diffusion of the incoming airflow, providing more uniform and stable airflow conditions for subsequent filtration by the stainless steel fine filter 22 and polyester fiber mesh 23, as well as for heat dissipation by the heat pipe cooling module 300.
[0060] Furthermore, the stainless steel fine filter 22 is configured with a tapering shape, from 0.8mm at the air inlet to 0.5mm at the end. This tapering accelerates airflow scouring and prevents large particles from getting stuck (reducing the clogging rate by 35% compared to traditional straight-hole filters).
[0061] Furthermore, the polyester fiber mesh 23 is configured with a three-layer gradient meltblown structure, with pore sizes of 8μm, 5μm, and 3μm from the air inlet side to the end. The three-layer gradient meltblown structure of the polyester fiber mesh 23 enables graded filtration of fine particulate impurities. The gradually decreasing pore size from the air inlet side to the end effectively filters fine particles of different sizes, improving filtration accuracy and ensuring clean air entering the heat dissipation system. It is manufactured using a meltblown process. During installation, the polyester fiber mesh 23 is installed inside the stainless steel fine filter 22. After initial filtration by the stainless steel fine filter 22, air enters the polyester fiber mesh 23. The three-layer gradient meltblown structure of the polyester fiber mesh 23 enables graded filtration of fine particulate impurities. The gradually decreasing pore size from the air inlet side to the end effectively filters fine particles of different sizes, such as dust and pollen, improving filtration accuracy and ensuring clean air entering the heat dissipation system, thus guaranteeing the normal operation of the heat dissipation system.
[0062] Furthermore, a return air duct 12 is provided at the bottom of the housing 100, and the other end of the return air duct 12 is connected to the leeward side of the stainless steel fine filter 22. The return air duct 12 is equipped with a return air fan 13. Utilizing the Venturi effect, 5% of the airflow is diverted back to the back of the outer filter, forming a reverse flushing airflow (tests show that this can reduce particulate matter retention by 20%).
[0063] Specifically, a hole for the return air duct 12 is precisely measured and drilled at the bottom of the housing 100 (more precisely, the bottom sidewall). A return air duct 12 with a diameter of 5mm is selected. This diameter, after actual testing and calculation, effectively balances the airflow resistance within the duct and the power requirements of the return airflow while meeting the airflow and suction requirements of the Venturi effect. The return air duct 12 is made of corrosion-resistant metal materials, such as stainless steel, to ensure that its structural strength and durability are not affected in complex operating environments. During installation, one end of the return air duct 12 is tightly connected to the opening at the bottom of the housing 100. The connection is sealed with sealant or welding to ensure a good seal and prevent outside air from mixing in and affecting the back suction effect. The other end is precisely connected to the leeward side of the stainless steel fine filter 22, ensuring the same sealing and firmness of the connection.
[0064] A return air fan 13 is installed on the return air duct 12. The power of the return air fan 13 needs to be reasonably selected based on the actual size of the radiator, the dust accumulation of the filter assembly 200, and the characteristics of the 5mm diameter return air duct 12. A return air fan 13 with sufficient power should be selected to generate enough suction within the return air duct 12 to achieve the effect of drawing 5% of the airflow back to the back of the outer filter using the Venturi effect. The installation position of the return air fan 13 should be close to the inlet end of the return air duct 12 to ensure effective airflow within the duct.
[0065] Operation: When the entire radiator system is running, fan 41 exhausts hot air from the air guide shroud 400, forming the main airflow channel. After the return air fan 13 starts, it generates a high-speed airflow within the 5mm diameter return air duct 12. According to the Venturi effect, at a specific location in the return air duct 12 (usually the throat where the diameter narrows; in this design, the outlet structure of the return air fan 13 is used to create the throat effect), the airflow velocity increases and the pressure decreases. At this time, this low-pressure area is connected to the outside air, allowing approximately 5% of the airflow within the casing 100 to be drawn into the return air duct 12. This drawn-in airflow mixes with the original airflow within the return air duct 12 and is then guided to the leeward side of the stainless steel fine filter 22. Since this airflow is a reverse flush from the back of the outer filter, opposite to the normal airflow direction, it effectively flushes away dust and particles accumulated on the stainless steel fine filter 22.
[0066] Operating Principle: The core of the Venturi effect lies in the fact that when fluid (in this case, air) passes through a narrow throat in a pipe, its velocity increases. According to Bernoulli's principle, this increased velocity leads to a decrease in pressure. In this design, a 5mm diameter return air duct 12, working in conjunction with a return air fan 13, creates conditions within the duct that satisfy the Venturi effect. Utilizing this pressure difference, outside air is drawn into the return air duct 12, forming an additional airflow. This airflow is directed back to the back of the outer filter screen, providing a reverse flush. Tests show that this reverse flushing airflow effectively reduces particulate matter retention on the filter screen by 20%. Through continuous reverse flushing, the stainless steel fine filter screen 22 remains clean, preventing a decrease in filtration efficiency and heat dissipation performance due to dust accumulation. Simultaneously, because the cleanliness of the filter assembly 200 is maintained, its service life is extended, ensuring the long-term stable operation of the heat dissipation system. Furthermore, this design utilizing the Venturi effect cleverly leverages the system's own airflow dynamics, eliminating the need for additional complex equipment or high energy consumption, thus offering the advantages of high efficiency and energy saving.
[0067] Furthermore, the filtering component 200 includes:
[0068] The frame 27 has a pair of annular grooves on its inner sidewall and a pair of slots on its top that correspond to and communicate with the pair of grooves. The stainless steel fine filter screen and the polyester fiber mesh 23 are respectively sealed through the pair of slots and sealed and limited in the pair of grooves. The V-shaped guide ribs 24 are connected by multiple connecting rods and connected to the inner side of the frame 27.
[0069] Cover plate 29, the sealing cover of which is provided on a pair of grooves;
[0070] A pair of knobs 28 are located on the top of the frame 27, and the knobs 28 are rotated to press or release the cover plate 29.
[0071] In the above technical solution, the design of the frame 27, slot, groove, cover plate 29 and knob 28 makes the installation and disassembly of the filter assembly 200 more convenient and quick, facilitates the cleaning and replacement of the stainless steel fine filter screen 22 and polyester fiber screen 23, and improves the maintenance efficiency of the heat dissipation system.
[0072] Specifically, a pair of annular grooves are precisely machined into the inner wall of the frame 27, and a pair of slots communicating with the grooves are correspondingly opened at the top. A stainless steel fine filter screen 22 and a polyester fiber mesh 23 are carefully sealed through the slots and tightly fixed within the grooves. The V-shaped guide ribs 24 are connected as a whole by multiple connecting rods and then securely connected to the inner side of the frame 27 to ensure they do not loosen under airflow impact. A cover plate 29 matching the grooves is fabricated and sealed onto the grooves. A pair of knobs 28 are installed on the top of the frame 27, and the knobs 28 are threadedly connected to the frame 27. When the filter assembly 200 needs to be installed, the stainless steel fine filter screen 22 and the polyester fiber screen 23 are placed into the slot and fixed in the groove. Then, the cover plate 29 is put on and the knob 28 is rotated to press the cover plate 29 down, thereby achieving a sealed installation of the filter assembly 200. When it is necessary to disassemble and clean, the knob 28 is rotated in the opposite direction to loosen the cover plate 29, and the stainless steel fine filter screen 22 and the polyester fiber screen 23 can be easily taken out for cleaning or replacement, which greatly improves the convenience of maintenance.
