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] A diesel generator set uses diesel as fuel, driving an internal combustion engine to generate electricity. It is widely used in areas with insufficient power supply, emergency power supply, or lack of access to the power grid. It consists of a diesel engine, generator, electronic control system, cooling system, exhaust system, and lubrication system. The working principle of a diesel generator set is as follows: the diesel engine generates mechanical energy by burning diesel, which drives the generator to convert mechanical energy into electrical energy to provide power to external devices. During operation, the combustion of diesel releases a large amount of heat, which needs to be effectively removed by the cooling system to ensure that the engine operates within the appropriate operating temperature range and avoid damage or reduced efficiency due to 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. This 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 the excessive heat, causing the unit to overheat and may even affect the stability and life of the unit.

However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] See also Figure 1 and Figure 2The present invention provides a technical solution: a cooling system for a diesel generator set, comprising a rectangular support 1 and a door-shaped frame 2 fixedly connected to the upper end face of the rectangular support 1, and a sliding groove is opened on the opposite sides of the vertical section of the door-shaped frame 2, and a plurality of double-support plate groups are equidistantly slidably connected between the two sliding grooves by interference fit.

[0032] See also Figure 2 and Figure 5 In this embodiment, the assembled cooling module 4 includes a rectangular frame 41, two inverted U-shaped clamping sleeves 42 symmetrically distributed and fixedly connected to the side of the rectangular frame 41 close to the strip support plate 3, and a heat dissipation component 43 arranged on the bottom of the rectangular frame 41. The horizontal section of the rectangular frame 41 is symmetrically provided with an embedding groove 44. The left and right parts of the heat dissipation component 43 are respectively provided with a docking connection component 45 for fitting with the embedding groove 44. The inverted U-shaped clamping sleeve 42 is used to be movably sleeved on the outside of the strip support plate 3. The upper end surface of the strip support plate 3 is equidistantly provided with a plurality of An arc-shaped limit groove is formed, and the upper cavity wall of the inverted U-shaped sleeve 42 is fixedly connected with an arc-shaped limit block that cooperates with the arc-shaped limit groove. When the assembled cooling module 4 is placed on the strip support plate 3, the arc-shaped limit block is inserted into the arc-shaped limit groove to ensure the stability of the inverted U-shaped sleeve 42 when placed, avoiding the situation where the U-shaped sleeve slides randomly. A mounting frame is fixedly connected between the transverse section of the door frame 2 and the rectangular support 1, and a number of fans 10 distributed in a matrix are rotatably arranged on the mounting frame. The fan 10 is located between two adjacent strip support plates 3 in the front and rear.

[0033] See also Figure 5 and Figure 7 The heat dissipation component 43 includes several U-shaped tubes 431 fixedly connected to the lower cavity wall of the rectangular frame 41 at equal intervals by fixing rods. The adjacent vertical sections of the two adjacent U-shaped tubes 431 are slidably connected with an inverted U-shaped adjustment tube 432. The lower part of the outer wall of the vertical section of the inverted U-shaped adjustment tube 432 is fixedly connected with a plug ring 433 that fits in the inner wall of the U-shaped tube 431. The two docking and connecting components 45 are respectively installed on the U-shaped tube 431 located on the left and right parts. A limit ring 11 for limiting the plug ring 433 is fixedly connected to 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 mounting 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 that cooperate 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 connected to a connecting hose 453. The end of the rotating tube 452 away from the U-shaped tube 431 is connected to a tube 454 arranged perpendicular to it. An inner tube 455 is rotatably connected in the tube 454, and the inner tube 455 is connected to the tube 454. They are connected, and an arc-shaped groove is opened on the tube 454 along its own curvature. The outer wall of the inner tube 455 is connected with a docking tube 456 passing through the arc-shaped groove. One of the docking tubes 456 in the two docking connecting components 45 is slidably connected to the outside of a pipe sleeve 457, and a top spring is fixedly connected between the pipe sleeve 457 and the docking tube 456. The inner cavity of the pipe sleeve 457 is fixedly connected with several sealing rings at equal distances along its own axis. The upper and lower opposite sides of the rectangular frame 41 are symmetrically provided with a groove group corresponding to and connected to the embedded groove 44 for the docking tube 456 to lie in. The groove group consists 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 embedded seat 451 into the embedded groove 44 at the bottom, and turn the docking pipe 456 to a horizontal state. At this time, the docking pipe 456 "lies" inside the groove section 9 located 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. At this time, the ends of the adjacent docking pipes 456 in the two rectangular frames 41 are in contact with 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. Then, the pipe sleeve 457 on the outside of one of the butt joints 456 is pressed to slide. When the ends of the longitudinally corresponding butt joints 456 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 docking pipe 456 at points a and b in the figure, the cooling water enters the docking pipe 456, then 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 air flow to flow on the outer walls of the U-shaped pipe 431 and the inverted U-shaped regulating pipe 432, quickly dissipating the heat generated during the operation of the diesel generator set. The cooling water that has completed cooling after flowing through the assembled assembled cooling module 4 flows into the water channel of the diesel generator set again.

[0037] In addition, if the heat output 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 the cooling water enters the U-shaped tube 431 and the inverted U-shaped regulating tube 432, the volume will expand 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 overall contact area between the U-shaped tube 431 and the inverted U-shaped regulating tube 432 and the airflow, 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 falling out of 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 in the shape of a right-angled trapezoidal block rotatably connected to the left end surface of the rectangular support 1, 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 splicing block 2 61 rotatably connected to the right end surface of the rectangular support 1 in the shape of a right-angled trapezoidal block, a tongue 1 62 slidingly connected to the splicing block 2 61 for cooperating with the slot 1 52, and a tongue 2 63 slidingly connected to the splicing block 2 61 and arranged perpendicularly to the inclined surface of the splicing block 2 61 for cooperating with the slot 2 53. A strip groove for mounting the tongue 1 62 is provided in the splicing block 2 61, and a reset spring is fixedly connected between the strip groove and the tongue 1 62. A mounting groove 64 is provided in the splicing block 2 61, and the tongue 2 63 is slidingly connected to the splicing block 2 In the mounting groove 64, a return spring is fixedly connected between the second 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 tongue 63 is fixedly connected between the slide bar 65 and the mounting groove 64. The right end surface of the rectangular support 1 is fixedly connected to an arc-shaped protrusion 68 for respectively cooperating with the second tongue 63 and the slide bar 65. Two bar through grooves 67 are respectively connected to the strip groove and the mounting groove 64 and are used for the arc 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 and rear directions needs to be lengthened, multiple rectangular supports 1 are arranged front to back, and the adjacent docking tongues 7 are inserted into the docking grooves 8 to splice the multiple rectangular supports 1 together front to back.

[0042] When it is necessary to increase the cooling range in the horizontal direction, the rectangular support 1 is 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 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. Then, the adjacent rectangular supports 1 are pushed closer to each other and moved 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 in 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 the shape of a "C". When splicing the rectangular supports 1 at the corners, rotate the second splicing block 61 by 180 degrees. When the second splicing block 61 has completed rotation, 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 in a direction 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 second tongue 63 to move, causing the second tongue 63 to extend from the second splicing block 61. At this time, the first splicing block 51 and the second splicing block 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 first tongue 62 will be pulled and retracted into the first splicing block 51 under the action of the return spring). Then, adjust the position of the rectangular support 1 so that the inclined surface of the rotated second splicing block 61抵触 another first splicing block 51's inclined surface. At the same time, the second tongue 63 will also be inserted into the second slot 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 path of the diesel generator set is introduced into the assembled cooling module 4 on multiple assembled rectangular supports 1 for cooling work. (Specifically as Figure 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 applicable to a diesel generator set with less heat, select a single portal frame 2 and install a certain number of assembled cooling modules 4 inside it for assembly. That's it. When used for a diesel generator set with high heat or when the heat generation of the diesel generator set increases, multiple rectangular supports 1 with assembled cooling modules 4 are spliced together using the female splice joint 5 and the male splice joint 6. They can be spliced horizontally, longitudinally front and back, or along the shape of a "C", so that the cooling range can be flexibly adjusted according to the different heat generations of the diesel generator set.
