Description

Technical Field

[0001] The invention relates to the technical field of diesel generator sets, in particular to a cooling system for a diesel generator set. Background Art

[0002] Diesel generator sets are devices that use diesel as fuel and drive generator sets to generate electricity through internal combustion engines. They are widely used in areas with insufficient power supply, emergency power supply or inaccessible power grids. They are composed of diesel engines, generators, electronic control systems, cooling systems, exhaust systems, lubrication systems, etc. The working principle of diesel generator sets is: the diesel engine generates mechanical energy by burning diesel, drives the generator to convert mechanical energy into electrical energy, and provides electricity for external equipment; during the operation of the diesel engine, the burning of diesel will release a lot of heat, which needs to be effectively removed by the cooling system to ensure that the engine operates within a suitable operating temperature range to avoid damage or reduced efficiency caused by overheating.

[0003] However, in traditional diesel generator sets, cooling equipment is mostly installed outside the unit and as part of the overall system, these cooling devices are usually designed as fixed-position radiators with a predetermined and non-adjustable heat dissipation range, which means that when the unit is running, the heat dissipation efficiency and range of the cooling equipment are fixed and cannot be adjusted according to changes in the external environment or the load of the generator set. Therefore, when the load of the diesel generator set is large or the ambient temperature is high, the heat dissipation capacity of the traditional cooling equipment may not be able to effectively cope with excessive heat, causing the unit to overheat, and may even affect the stability and life of the unit.

Two docking connecting components 45 are respectively installed on the U-shaped tube 431 located at the left and right parts, and a limit stop ring 11 for limiting the plug ring 433 is fixedly connected at the port of the U-shaped tube 431.

[0034] See also Figure 5 and Figure 6 The docking connection component 45 includes an embedding seat 451 for installation and matching with the embedding groove 44. The left and right opposite sides of the embedding groove 44 are fixedly connected with positioning strips. The left and right sides of the embedding seat 451 are provided with positioning slots matching with the positioning strips. A rotating tube 452 is rotatably connected in the embedding groove 44. The end of the rotating tube 452 close to the U-shaped tube 431 and the corresponding U-shaped tube 431 are commonly connected with a connecting hose 453. The end of the rotating tube 452 away from the U-shaped tube 431 is connected with a tube 454 arranged vertically therewith. An inner tube 455 is rotatably connected in the tube 454, and the inner tube 455 is connected to the tube 454. The tube 454 is connected to each other, an arc-shaped through groove is opened on the upper surface of the tube 454 along its own curvature, the outer wall of the inner tube 455 is connected to a docking tube 456 passing through the arc-shaped through groove, one of the docking tubes 456 in the two docking connecting components 45 is slidably connected to the outside with a pipe sleeve 457, a top spring is fixedly connected between the pipe sleeve 457 and the docking tube 456, a plurality of sealing rings are fixedly connected to the inner cavity of the pipe sleeve 457 at equal distances along its own axis, and a groove group corresponding to and connected to the embedding groove 44 for the docking tube 456 to lie in is symmetrically opened on the upper and lower opposite sides of the rectangular frame 41, and the groove group is composed of two groove sections 9 arranged perpendicular to each other.

[0035] When cooling a diesel generator set with a smaller heating range, if a single door-type frame 2 is sufficient for cooling, then select a suitable number of assembled cooling modules 4 and slide them on the strip support plate 3 using the inverted U-shaped sleeve 42, then slide the embedding seat 451 into the embedding groove 44 at the bottom, turn the docking pipe 456 to a horizontal state, at which time the docking pipe 456 "lies" inside the groove section 9 in the horizontal direction, and then push the horizontal rectangular frames 41 to move closer to each other, and push the horizontal rectangular frames 41 to move closer to each other, and the docking connecting components 45 in the two adjacent rectangular frames 41 move closer to each other, so that one of the docking pipes 456 in the two adjacent rectangular frames 41 is inserted into the pipe sleeve 457 of the other one, and at this time, the ends of the adjacent docking pipes 456 in the two rectangular frames 41 are butted against each other.

[0036] After the assembled cooling modules 4 are connected and spliced ​​in the horizontal direction, one of the assembled cooling modules 4 in the horizontal arrangement is selected and the butt joint 456 in the assembled cooling module 4 is rotated to make the butt joint 456 become a vertical state, and then the pipe sleeve 457 outside one of the butt joints 456 is pressed to slide, and when the ends of the butt joints 456 corresponding in the longitudinal direction are in the same straight line, the pipe sleeve 457 is pushed in the reverse direction to move until it is sleeved on the outside of the other butt joint 456. After all the assembled cooling modules 4 in the door frame 2 are assembled and connected together, the water inlet and water outlet in the cooling water path of the diesel generator set are respectively connected to the water inlet and water outlet in the cooling water path of the diesel generator set. Figure 8In the butt-joint pipe 456 at points a and b in the figure, after the cooling water enters the butt-joint pipe 456, it flows into the U-shaped pipe 431 through the connecting hose 453, and then enters the inverted U-shaped regulating pipe 432. At this time, the fan 10 is controlled to run, and the fan 10 drives the airflow to flow on the outer walls of the U-shaped pipe 431 and the inverted U-shaped regulating pipe 432, so as to quickly discharge the heat generated during the operation of the diesel generator set. The cooling water that has completed the cooling by flowing through the assembled cooling module 4 and flows into the water channel of the diesel generator set again.

[0037] In addition, if the heat generation of the diesel generator set to be cooled is smaller, the number of assembled rows of the assembled cooling modules 4 can be less than the number of double support plate groups, and can be flexibly adjusted according to demand.

[0038] When cooling water enters the U-shaped tube 431 and the inverted U-shaped regulating tube 432, the volume expands due to the heat, thereby pushing the inverted U-shaped regulating tube 432 upward, and the inverted U-shaped regulating tube 432 then drives the plug ring 433 upward, thereby increasing the contact area between the U-shaped tube 431 and the inverted U-shaped regulating tube 432 and the airflow as a whole, accelerating the cooling speed of the diesel generator set, and using the limit ring 11 to limit the plug ring 433 to prevent the plug ring 433 from escaping from the U-shaped tube 431.

[0039] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the female splicing joint 5 includes a splicing block 51 rotatably connected to the left end surface of the rectangular support 1 and in the shape of a right-angled trapezoidal block, a slot 52 opened on the inclined surface of the splicing block 51 and running horizontally, and a slot 2 53 opened on the inclined surface of the splicing block 51 and perpendicular to the inclined surface of the splicing block 51.

[0040] See also Figure 1 , Figure 3 and Figure 4The male joint 6 includes a second splicing block 61 rotatably connected to the right end surface of the rectangular support 1 in the shape of a right-angled trapezoidal block, a tongue 62 that is slidably connected to the second splicing block 61 for cooperating with the first slot 52, and a tongue 63 that is slidably connected to the second splicing block 61 and arranged perpendicularly to the inclined surface of the second splicing block 61 for cooperating with the second slot 53. A strip groove for installing the tongue 62 is provided in the second splicing block 61, and a return spring is fixedly connected between the strip groove and the tongue 62. An installation groove 64 is provided in the second splicing block 61, and the tongue 63 is slidably connected to the second splicing block 61. In the mounting groove 64, a return spring is fixedly connected between the second plug tongue 63 and the mounting groove 64, a slide bar 65 is slidably connected in the mounting groove 64, and a wedge block 66 whose inclined surface conflicts with the second plug tongue 63 is fixedly connected between the slide bar 65 and the mounting groove 64. An arc-shaped protrusion 68 for respectively cooperating with the second plug tongue 63 and the slide bar 65 is fixedly connected to the right end surface of the rectangular support 1, and two strip through grooves 67 are respectively connected to the strip groove and the mounting groove 64 and are used for the arc-shaped protrusion 68 to slide into.

[0041] When cooling a diesel generator set with a large heat range or a diesel generator set with increased heat generation, multiple door frames 2 with fully assembled cooling modules 4 are selected for splicing. When the heat dissipation range in the front-to-back direction needs to be lengthened, multiple rectangular supports 1 are arranged front to back, and the multiple rectangular supports 1 can be spliced ​​together front to back by inserting adjacent docking tongues 7 into docking grooves 8.

[0042] When it is necessary to increase the cooling range in the horizontal direction, the rectangular supports 1 are first placed horizontally in sequence, and then the splicing block 1 51 and the splicing block 2 61 are rotated so that the inclined surfaces of the splicing block 1 51 and the splicing block 2 61 installed on the rectangular support 1 are parallel to each other. At this time, the arc-shaped protrusion 68 is located in the position of the strip through groove 67 of the strip groove, that is, the arc-shaped protrusion 68 now abuts against the plug tongue 1 62, and the plug tongue 1 62 is in a state of extending out of the splicing block 2 61, and the plug tongue 2 63 is now retracted into the splicing block 2 61, and then the adjacent rectangular supports 1 are pushed to move closer to each other until the inclined surfaces of the splicing block 1 51 and the splicing block 2 61 abut against each other, and at the same time, the plug tongue 1 62 is also inserted into the slot 1 52, so that the splicing of the rectangular supports 1 at multiple horizontal positions can be completed.

[0043] When cooling the surrounding area of a diesel generator set, multiple rectangular supports 1 can be spliced along a C-shaped configuration. When splicing the rectangular supports 1 at the corners, the splicing block two 61 is rotated 180 degrees. After the splicing block two 61 is rotated, the arc-shaped convex block 68 is located in the strip-shaped through groove 67 at the position of the installation groove 64. At this time, the arc-shaped convex block (68) will push against the slide bar 65 and move it away from the rectangular support 1. The slide bar 65 then drives the wedge block 66 to move. During the movement of the wedge block 66, its inclined surface will squeeze the insertion tongue two 63 to move, causing the insertion tongue two 63 to protrude from the splicing block two 61. At this time, the splicing block one 51 and the splicing block two 61 jointly form an isosceles trapezoid shape. (When the arc-shaped convex block 68 moves away from the position of the strip-shaped groove, the insertion tongue one 62 will be pulled and retracted into the splicing block one 51 under the action of the return spring.) Then, the position of the rectangular support 1 is adjusted so that the inclined surface of the rotated splicing block two 61 abuts against the inclined surface of another splicing block one 51. At the same time, the insertion tongue two 63 will also be inserted into the slot two 53, thereby completing the assembly of multiple rectangular supports 1 at the corners. After all the rectangular supports 1 are assembled together, the cooling water circuit of the diesel generator set is introduced into the assembled cooling module 4 on multiple assembled rectangular supports 1 for cooling work. (Specifically as Fig. 9 shown).

[0044] During operation, first select an appropriate number of assembled cooling modules 4 and rectangular frame 41 according to the heat range of the diesel generator set. When applying to a diesel generator set with low heat, select a single U-shaped frame 2 and install a certain number of assembled cooling modules 4 inside for assembly. When applying to a diesel generator set with high heat or when the heat generation of the diesel generator set increases, multiple rectangular supports 1 assembled with assembled cooling modules 4 are spliced together using the female splicing joint 5 and the male splicing joint 6. They can be spliced horizontally, longitudinally front and back, or along a C-shaped configuration, so that the cooling range can be flexibly adjusted according to the different heat generations of the diesel generator set.
