Technical Field

[0001] This utility model relates to the field of fuel pump technology, and more specifically to a fuel pump assembly with a controller cooling function. Background Technology

[0002] The fuel pump is mainly responsible for drawing fuel from the fuel tank and delivering it to the engine at a certain pressure, thereby maintaining a stable and continuous fuel supply and ensuring that the engine can output fuel stably.

[0003] A fuel pump consists of a pump, a controller, and a fuel nozzle. The controller drives the pump to generate negative pressure, which draws fuel from the fuel tank and outputs it to the fuel nozzle. The fuel nozzle is then connected to an external fuel line to supply fuel to the engine. However, during high-frequency engine operation, the temperature inside the car inevitably rises, especially in the controller section. If the controller reaches its rated temperature, it can damage the electronic components inside, causing the fuel pump to malfunction. Utility Model Content

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0031] like Figure 1-6 As shown, a fuel pump assembly with a controller cooling function includes:

[0032] Top cover 1, on which a control unit 4 is provided;

[0033] Oil outlet 2 is provided on the upper cover 1 and located on one side of the control unit 4. Oil outlet 2 is provided with an oil outlet end 13, which is engaged with the delivery pipe 8.

[0034] Heat sink 9 is positioned directly below control unit 4;

[0035] Connector 7 is snapped onto heat dissipation column 9. One end of connector 7 is provided with oil supply pipe 6, and the other end is provided with delivery pipe 8 that is connected to oil outlet 2.

[0036] Specifically, the top cover 1 is mounted on the fuel tank so that the fuel outlet 2 is exposed. When the fuel pump is running, the fuel is output through the fuel supply pipe 6 to the connecting joint 7, and then along the delivery pipe 8 to the fuel outlet 2, from where it is delivered to the engine. However, during operation, the control unit 4 inevitably generates a lot of heat due to its continuous control of the opening and closing of various valves of the fuel pump and the operation of the filter 15. Since the control unit 4 is a core component and is often protected by a seal, the heat dissipation effect is limited. After long-term operation, the heat of the control unit 4 will rise sharply, and overheating will cause damage to some parts. By setting a heat dissipation column 9 on the top cover 1, the heat dissipation column 9 is in contact with the controller in the control unit 4 to achieve the effect of heat absorption. Then, the fuel is output through the fuel supply pipe 6 so that the fuel can fully exchange heat with the heat dissipation column 9, thereby reducing the internal temperature of the control unit 4 and reducing the phenomenon of overheating and damage to parts.

[0037] As a further embodiment of this utility model, the control unit 4 includes a mounting shell 44 and a cover plate 42 that engages with the mounting shell 44. The cover plate 42 engages with the mounting shell 44 to form a mounting cavity. A controller that abuts against the heat dissipation column 9 is provided in the mounting cavity. The controller controls the switching of the filter 15, the oil pump, and various valves located in the inner bracket 52. The mounting cavity is a relatively sealed space to protect the controller from damage caused by external forces. When the controller is running, its heat is transferred to the heat dissipation column 9 to dissipate heat from the controller.

[0038] As a further embodiment of this utility model, the cover plate 42 is provided with a buckle 43, which engages with the mounting shell 44. Multiple sets of buckles 43 are evenly distributed on the annular outer wall of the cover plate 42, with at least three sets of buckles 43, so that the cover plate 42 is fixed to the mounting shell 44 by the buckles 43.

[0039] As a further embodiment of this utility model, the heat dissipation column 9 includes a first connection port 91, a second connection port 92, and a third connection port 94. The first connection port 91 is engaged directly below the control unit 4, and the third connection port 94 cooperates with the connecting connector 7. Sealing elements are provided at both the first connection port 91 and the third connection port 94 to improve the sealing performance at the connection points at both ends of the heat dissipation column 9. At the same time, the connection ports facilitate the installation of the heat dissipation column 9 onto the upper cover 1 and the installation of the connecting connector 7 onto the heat dissipation column 9.

[0040] As a further embodiment of this utility model, a U-shaped bracket 93 is provided on the second connection port 92, and a locking hole 72 that mates with the U-shaped bracket 93 is provided on the connection joint 7. The connection joint 7 is fixed to the heat dissipation column 9 by the U-shaped bracket 93. When the connection joint 7 is engaged with the heat dissipation column 9, the U-shaped bracket 93 is passed through the locking hole 72 so that the crossbar of the U-shaped bracket 93 abuts against the second connection port 92, so that the connection joint 7 is firmly fixed to the heat dissipation column 9. Furthermore, a limiting groove 71 is provided on the connection joint 7, and the limiting groove 71 mates with the upper cover 1 to limit the rotation of the connection joint 7.

[0041] As a further embodiment provided in this utility model, the heat dissipation column 9 is a copper column, which has good thermal conductivity, thereby improving the heat conduction effect on the control unit 4.

[0042] As a further embodiment provided by this utility model, the connecting joint 7 has a first connecting end 73 and a second connecting end 75. The first connecting end 73 is connected to the second connecting end 75. The first connecting end 73 is engaged with the oil supply pipe 6, and the second connecting end 75 is engaged with the delivery pipe 8. The first connecting end 73 is arranged horizontally, and the second connecting end 75 is arranged vertically (e.g., ...). Figure 4 As shown in the figure, this allows the oil supply pipe 6 to be vertically connected to the regulating valve, while the delivery pipe 8 can fit against the top cover 1, making the structure more reasonable and improving space utilization.

[0043] As a further embodiment provided by this utility model, both the first connecting end 73 and the second connecting end 75 are provided with a tapered protrusion 74. The tapered protrusion 74 improves the connection effect between the oil supply pipe 6 and the delivery pipe 8 and reduces the phenomenon of oil pipe detachment during the oil supply process.

[0044] As a further embodiment of this utility model, an oil pressure sensor 3 is provided on the fuel outlet 2. When fuel passes through the fuel outlet 2, the fuel output pressure is detected by the oil pressure sensor 3. When the oil pressure is too high, the output power of the oil pump at the center of the filter 15 is reduced, and when the oil pressure is too low, the output power of the oil pump is increased.

[0045] As a further embodiment of this utility model, a retaining seat 11 is provided on the upper cover 1, a support rod 5 is provided on the retaining seat 11, and an inner bracket 52 is provided at the end of the support rod 5. A filter 15 and a fuel pressure regulator 16 are respectively provided on the inner bracket 52. The filter 15 and the fuel pressure regulator 16 are connected. The fuel supply pipe 6 is engaged with the fuel pressure regulator 16. A reinforcing rib 12 is provided on the retaining seat 11 to improve the support effect on the support rod 5. A spring 51 is provided on the support rod 5. At the same time, a crossbeam 14 is provided on the upper cover 1 to improve the overall stability of the upper cover 1 when outputting. An oil pump is provided at the axis of the filter 15. When the pump draws fuel from the fuel tank, the fuel passes through the filter 15 to remove impurities. When the fuel pump is working, the fuel level sensor 17 detects the fuel level in the tank, and then the pump draws fuel from the tank so that the fuel passes through the fuel pressure regulator 16. When the fuel pressure is too high, the excess fuel is discharged back into the inner support 52 to keep the fuel under constant pressure. The fuel is then delivered from the fuel supply pipe 6 to the fuel connector 7, and then from the delivery pipe 8 to the fuel outlet 2 for output. The control unit 4 is equipped with a plug 41, through which an external control line is connected to transmit an electrical signal to the controller for real-time monitoring and control of the fuel.

[0046] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
