Description

Technical Field

[0001] The present application relates to the technical field of gear pumps, and in particular to an internal gear pump with a self-starting heat dissipation function. Background Art

[0002] Internal gear pumps are a common type of hydraulic pump, widely used for liquid delivery and pressure boosting. They operate by creating a closed working chamber through the rotation of two meshing gears within the pump body, allowing for the intake and discharge of liquids. During operation, internal gear pumps generate heat due to friction and fluid flow. Excessive heat can cause deformation or damage to the pump body and gears, impacting proper operation.

[0003] After searching, the announcement number is CN215719473U, which discloses a pump body with good heat dissipation performance and an internal meshing gear pump, including an oil inlet and an oil outlet. The oil inlet and the oil outlet are respectively provided with oil collecting grooves in the low-pressure area and high-pressure area corresponding to the inner wall of the pump body. In the high-pressure area, an oil drain groove is opened next to the oil collecting groove corresponding to the oil outlet on the side surface of the pump body, and the pump body is provided with an external oil leakage hole connected to the oil drain groove. The unreasonable aspects of the existing gear pump external leakage oil circuit are optimized. For the radial leakage between the gear ring and the inner wall of the pump body, an oil drain groove for collecting the internal leakage oil is set. The high-temperature oil leaked from this place is discharged to prevent it from entering the low-pressure chamber and forming a circulation inside the pump. Compared with the existing leakage structure, its effective leakage volume is greatly increased, ensuring timely discharge of heat and avoiding overheating problems.

[0004] However, although the existing pump body can reduce the problem of increased pump body temperature by designing a reasonable oil circuit, it lacks passive heat dissipation function. The internal temperature of the pump body cannot be effectively reduced by a reasonable oil circuit due to long-term operation, resulting in deformation or damage of the pump body and gear materials, thereby affecting the normal operation of the pump. At this time, it is necessary to add a passive cooling device outside the pump body to assist in cooling the pump body.

[0005] Therefore, it is necessary to provide an internal gear pump with a self-starting heat dissipation function to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0038] See also Figure 1-6 , the embodiment provided by the utility model:

[0039] An internal gear pump with a self-starting heat dissipation function includes a pump body 1. A pump tank 12 for transporting liquid is defined within the pump body 1. A water tank 13 is defined in a side wall of the pump body 1. A water inlet and a water outlet are defined on one side of the pump body 1. Both the water inlet and the water outlet are connected to the water tank 13. A water inlet connector 2 is provided on the water inlet, and a water outlet connector 3 is provided on the water outlet. A water inlet pipe 4 is plugged into and installed on the side wall of the water inlet connector 2, and a water outlet pipe 5 is plugged into and installed on the side wall of the water outlet connector 3.

[0040] The low-temperature coolant outside the housing 11 is introduced into the water inlet tank 13 through the water inlet pipe 4, and then the heated coolant is pumped out from the water tank 13 through the water outlet pipe 5 to reduce the long-term working temperature of the gears in the internal gear pump.

[0041] A heat-conducting component 8 is installed on the side wall of the pump body 1. The heat-conducting component 8 includes a connecting frame 81, a mounting plate 83, a second heat dissipation fin 84 and a heat-absorbing aluminum plate 85. One side of the connecting frame 81 is fixedly mounted on the side wall of the mounting frame 61 by screws, and the other side of the connecting frame 81 is fixedly mounted on the side wall of the shell 11 by screws. The mounting plate 83 is fixedly connected to the inner top of the connecting frame 81, and multiple second heat dissipation fins 84 are fixedly connected to the bottom surface of the mounting plate 83. One side of the heat-absorbing aluminum plate 85 is in contact with the side wall of the shell 11, and the other side of the heat-absorbing aluminum plate 85 is integrally connected to the multiple second heat dissipation fins 84. Air inlet slots 82 are respectively provided on the side walls of the connecting frame 81.

[0042] The heat radiated from the inside of the shell 11 to the surface of the shell 11 is absorbed by the heat-absorbing aluminum plate 85 , and then the heat is conducted to the second heat dissipation fins 84 to increase the heat dissipation area, which is beneficial to reducing the operating temperature of the pump body 1 .

[0043] Furthermore, a water cooling assembly 6 is installed on the side wall of the heat conducting assembly 8. The water cooling assembly 6 includes a mounting frame 61, a first water storage tank 62, a water pipe 63, a second water storage tank 64, a first heat dissipating fin and a pump body 1. The first water storage tank 62 and the second water storage tank 64 are fixedly connected by multiple water pipes 63, and the multiple water pipes 63 are respectively connected to the interior of the first water storage tank 62 and the second water storage tank 64. First heat dissipating fins 65 are installed in the gaps between the multiple water pipes 63. The mounting frame 61 is respectively fixedly installed on the side walls of the first water storage tank 62 and the second water storage tank 64. A water pump 66 is installed at the side wall of the water inlet pipe 4. A partition is fixedly connected in the middle of the internal side walls of the first water storage tank 62 and the second water storage tank 64. A reflux movement of water is formed between the first water storage tank 62 and the second water storage tank 64 through multiple water pipes 63.

[0044] The low-temperature coolant in the first water storage tank 62 and the second water storage tank 64 is extracted by the water pump 66, and then introduced into the water tank 13 inside the shell 11 through the water inlet pipe 4, and then the heated coolant is discharged into the first water storage tank 62 and the second water storage tank 64 and the multiple water pipes 63 again through the water outlet pipe 5, so that the coolant in the multiple water pipes 63 can be heat-dissipated by the first heat dissipation fins 65, thereby effectively reducing the problem of coolant.

[0045] Furthermore, an air-cooling assembly 7 is installed on the side wall of the water-cooling assembly 6. The air-cooling assembly 7 includes a mounting frame 71 and a fan 72. The fan 72 is installed inside the mounting frame 71. The mounting frame 71 is fixed to the side walls of the two mounting frames 61 by screws. The rotation of the fan 72 generates an outward suction force at the water-cooling assembly 6 and the heat-conducting assembly 8. Since the first heat sink fins 65 and the second heat sink fins 84 are wavy, the heated coolant and the shell 11 are heat-conducted to the first heat sink fins 65 and the second heat sink fins 84. The heat from the first heat sink fins 65 and the second heat sink fins 84 is absorbed by the cold air to reduce the temperature of the first heat sink fins 65 and the second heat sink fins 84. The reduction in the temperature of the first heat sink fins 65 and the second heat sink fins 84 can again provide a better heat absorption effect for the coolant, thereby further reducing the internal temperature of the shell 11.

[0046] The side wall of the pump body 1 is equipped with a temperature sensor to detect the temperature of the pump body 1. When the temperature is too high, the controller controls the water pump 66 and the fan 72 to automatically cool the pump body 1.

[0047] The pump body 1 is connected to the water cooling assembly 6 through the water tank 13 opened on the side wall and the water inlet pipe 4 and the water outlet pipe 5 to form a water circulation system. The circulation method of the coolant is as follows: as the water pump 66 introduces the low-temperature coolant into the water tank 13 in the shell 11 through the water inlet pipe 4, and then absorbs the temperature inside the shell 11, the coolant temperature rises. The increased coolant is introduced into the first water storage tank 62 again through the outlet pipe 5. The first water storage tank 62 enters the second water storage tank 64 through half of the water pipes 63 of the multiple water pipes 63. The coolant in the second water storage tank 64 enters the first water storage tank 62 again through the other half of the water pipes 63, so that the coolant forms a reflux on the first water storage tank 62, the second water storage tank 64 and the multiple water pipes 63. During the reflux process, the coolant is cooled by the first heat dissipation fins 65, thereby continuously providing a low-temperature operating environment for the pump body 1.

[0048] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
