Technical Field

[0001] This utility model relates to the field of electronic water pump technology for new energy vehicles, and specifically to an electronic water pump for new energy vehicles that facilitates heat dissipation. Background Technology

[0002] With the rapid development of new energy electric vehicles, the requirements for electric vehicle components are also getting higher and higher. The automotive electronic water pump plays an important role in new energy electric vehicles. As an important component of the automotive electronic water pump, the controller generates a lot of heat when it is working. If the heat is not discharged in time, it will affect the normal operation of various components of the electronic water pump, thereby reducing the service life of the automotive electronic water pump.

[0003] Therefore, it is necessary to invent a new energy vehicle electronic water pump that facilitates heat dissipation to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an electronic water pump for new energy vehicles that facilitates heat dissipation, in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic water pump for new energy vehicles that facilitates heat dissipation, comprising an electronic water pump body, a primary controller for controlling the operation of the electronic water pump body installed on the top of the electronic water pump body, and a heat dissipation component for forced convection heat dissipation of the primary controller installed on the top of the electronic water pump body, the heat dissipation component comprising a dustproof mesh cover, the primary controller being covered inside the dustproof mesh cover, a cooling fan installed at the middle position of the top of the dustproof mesh cover, a secondary controller for controlling the operation of the cooling fan installed on the surface of the dustproof mesh cover, the cooling fan being located directly above the primary controller, and a set of heat dissipation fins for auxiliary heat dissipation of the primary controller fixedly connected to each of the four outer walls of the primary controller.

[0006] The cooling fan uses an exhaust fan to quickly draw out the hot air around the controller, creating a strong convection effect, thereby reducing the operating temperature of the controller and extending its service life.

[0007] Preferably, each group of heat dissipation fins contains multiple fins, which are arranged in a linear array.

[0008] The heat dissipation fins design increases the heat dissipation area and improves heat dissipation efficiency, ensuring that the heat generated by the controller during operation can be dissipated in a timely manner, thereby maintaining the normal operating temperature of the controller.

[0009] Preferably, the heat dissipation fins are made of copper, and the surface of the heat dissipation fins has auxiliary holes for inducing airflow to form turbulence.

[0010] The heat dissipation fins are made of copper, which has excellent thermal conductivity and can quickly conduct the heat generated by the controller away. At the same time, auxiliary holes are opened on the surface of the heat dissipation fins. These holes can induce airflow to form turbulence, further enhancing the heat dissipation effect and improving the heat dissipation efficiency.

[0011] Preferably, four evenly distributed mounting pieces are fixedly connected at the bottom edge of the dustproof mesh cover, and the mounting pieces are close to the surface of the electronic water pump body.

[0012] The dustproof mesh cover is designed to ensure airflow around the controller, which is beneficial for heat dissipation. In addition, the dustproof mesh cover also has a dustproof function, which can prevent dust and other impurities from entering.

[0013] Preferably, the surface of the electronic water pump body is threaded with four evenly distributed hand-tightening screws, and the four hand-tightening screws are respectively matched with the four mounting parts.

[0014] The mounting parts can be secured by hand-tightening the screws, making it easy to fix the dust cover to the main body of the electronic water pump, and also facilitating subsequent disassembly and maintenance.

[0015] Preferably, the surface of the mounting component has an open slot, the hand-tightening screw engages with the open slot, and the end of the hand-tightening screw abuts against the surface of the mounting component.

[0016] The open slot design makes it easier and faster to match the hand-tightening screws with the mounting parts.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] 1. By setting a forced convection heat dissipation component on the top of the electronic water pump body, including a dust cover and a cooling fan, efficient heat dissipation of the No. 1 controller is achieved. The cooling fan adopts an exhaust form, which can quickly draw out the hot air around the No. 1 controller, forming a strong convection effect, thereby reducing the operating temperature of the No. 1 controller and extending its service life. At the same time, the design of the heat dissipation fins also enhances the auxiliary heat dissipation effect, further improving the overall heat dissipation performance.

[0019] 2. The dust cover is fixed to the main body of the electronic water pump by hand-tightening screws and clamping with the mounting parts, making the disassembly and installation of the dust cover very convenient. This facilitates regular cleaning and maintenance of the dust cover, thereby maintaining the normal heat dissipation effect of the heat dissipation components. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The electric water pump for new energy vehicles, which facilitates heat dissipation, includes an electric water pump body 1. A primary controller 2 is installed on the top of the electric water pump body 1 to control its operation. A heat dissipation component for forced convection cooling of the primary controller 2 is also installed on the top of the electric water pump body 1. The heat dissipation component includes a dustproof mesh cover 3. The primary controller 2 is covered inside the dustproof mesh cover 3. A cooling fan 4 is installed at the middle of the top of the dustproof mesh cover 3. A secondary controller 10 for controlling the operation of the cooling fan 4 is installed on the surface of the dustproof mesh cover 3. The cooling fan 4 is located directly above the primary controller 2. A set of heat dissipation fins 5 for auxiliary heat dissipation of the primary controller 2 is fixedly connected to each of the four outer walls of the primary controller 2.

[0029] In one aspect of this embodiment, each set of heat dissipation fins 5 is provided with multiple fins, which are arranged in a linear array. The heat dissipation fins 5 are made of copper. The surface of the heat dissipation fins 5 is provided with auxiliary holes 6 to induce airflow and form turbulence. Four evenly distributed mounting parts 7 are fixedly connected at the bottom edge of the dustproof mesh cover 3. The mounting parts 7 are close to the surface of the electronic water pump body 1. Four evenly distributed hand screws 8 are threadedly connected to the surface of the electronic water pump body 1. The four hand screws 8 are respectively matched with the four mounting parts 7. The surface of the mounting parts 7 is provided with an open slot 9. The hand screws 8 are engaged with the open slot 9, and the ends of the hand screws 8 are pressed against the surface of the mounting parts 7.

[0030] The electronic water pump body 1, controller 2, dustproof mesh cover 3, cooling fan 4 and controller 10 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-5 When using this utility model, the electronic water pump body 1 is first controlled by the No. 1 controller (2) to start working. During the working process, the No. 1 controller 2 will generate a lot of heat. If it is not dissipated in time, it will affect its normal operation and service life.

[0033] At this time, the heat dissipation components begin to function. Each of the four outer walls of the controller 2 is fixedly connected to a set of heat dissipation fins 5. These heat dissipation fins are made of copper and have good thermal conductivity. The surface of the heat dissipation fins is provided with auxiliary holes 6. These holes can induce airflow to form turbulence, thereby enhancing the heat dissipation effect. When the air passes through the heat dissipation fins 5, it will carry away the heat on the fins, achieving initial heat dissipation.

[0034] At the same time, the second controller 10 installed on the surface of the dustproof mesh cover 3 controls the cooling fan 4 to start working. The cooling fan 4 is located at the top center of the dustproof mesh cover 3. By rotating, it generates an upward suction force, which quickly draws out the hot air around the first controller 2 and discharges it into the outside environment. Meanwhile, the fresh air outside the dustproof mesh cover 3 will rush to the area around the first controller 2, forming a strong convection effect, thereby further improving the heat dissipation efficiency.

[0035] The dustproof mesh cover 3 not only serves the purpose of air circulation, but also has a dustproof function, which can prevent dust and other impurities from entering and avoid affecting the normal operation of the cooling fan 4 and the heat dissipation fins 5.

[0036] The dust cover 3 is fixedly connected to the electronic water pump body 1 through the mounting part 7 at its bottom. The mounting part 7 has an open slot 9 on its surface, which is engaged and tightened with the hand screw 8 threaded on the surface of the electronic water pump body to ensure the stable installation of the dust cover 3. Regularly disassembling and cleaning the dust cover 3 is beneficial to maintaining the normal heat dissipation effect of the heat dissipation components.
