Description

Technical Field

[0001] This utility model relates to the field of vehicle cooling fan technology, and in particular to a cooling fan controller assembly with good heat dissipation performance. Background Technology

[0002] With economic development and the rapid growth of the automotive industry, users now have higher requirements for vehicle intelligence and comfort, in addition to demanding power and stability.

[0003] To ensure the cooling of various engine components, different cooling fans are needed to dissipate heat from the powertrain system, depending on the actual vehicle conditions. The cooling fans are powered by an internal motor to cool the engine and related components. Nowadays, cooling fans are equipped with controllers to achieve precise control of heat dissipation. As the requirements for heat dissipation of the whole vehicle become higher, the requirements for the controllers are also becoming higher. Under high response and high load conditions, how to effectively control the heat generation of the controller so that it can work normally and stably is an urgent problem to be solved, and therefore, it is necessary to improve it. Utility Model Content

[0004] This utility model provides a cooling fan controller component with stable structure and excellent heat dissipation, which can effectively improve the heat dissipation of the controller and solve the problem that the performance of the current cooling fan controller is prone to degradation after overheating, thus meeting higher production requirements. It solves the technical problem that the current cooling fan has poor heat dissipation effect, performance degradation after overheating, and cannot meet the higher production and use requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a cooling fan controller assembly with good heat dissipation includes a metal substrate. A connector and a capacitor / inductor, encapsulated together, are fixedly mounted on the bottom of the substrate. A PCBA is spaced apart on the top of the substrate, and a fan assembly is mounted on top of the PCBA. In this utility model, the connector and the capacitor / inductor are encapsulated together, while the capacitor / inductor and the PCBA are assembled separately, avoiding heat accumulation caused by insufficient component spacing. The substrate is made of metal, providing good support while achieving effective heat dissipation through tight fit. The cooling fan controller assembly of this utility model has no external housing; the airflow driven by the fan greatly improves heat dissipation performance.

[0006] Preferably, the substrate is made of aluminum. The aluminum substrate in this invention provides good support while achieving effective heat dissipation through close contact.

[0007] Preferably, the substrate surface is provided with a plurality of positioning posts, and the PCBA is fixed on the positioning posts. The positioning posts can be used for soldering and positioning the PCBA, and at the same time can isolate the PCBA from the substrate to ensure heat dissipation.

[0008] Preferably, a gap is left between the substrate and the PCBA. The gap between the substrate and the PCBA allows for air circulation, effectively increasing the heat dissipation of the structure.

[0009] Preferably, the connector has pins that penetrate the substrate and connect to the PCBA. In this invention, the connector is plastic-coated with the capacitors and inductors and connected to the PCBA via pins. The capacitors and inductors are assembled separately from the PCBA, avoiding heat accumulation caused by excessively small component spacing.

[0010] Preferably, the PCBA has three-phase pins soldered on it to mate with the fan assembly. The three-phase pins are connected to the controller module of the fan assembly.

[0011] Preferably, the fan assembly includes a motor housing that mates with the PCBA. The motor housing houses a rotating shaft and a motor drive module, with fan blades fixed to the end of the rotating shaft. The electrical drive module includes a controller module, a stator, a rotor structure, etc., and the rotating shaft drives the fan to rotate.

[0012] Preferably, the motor housing has a metal base encased in plastic, the shaft is mounted on the base, and the three-phase pins are also encased in plastic on the base. In this invention, the motor shaft is fixedly mounted on the metal base, and the three-phase pins of the motor controller are also fixed to the base using plastic encapsulation, greatly improving the stability of the product.

[0013] Preferably, the motor housing surface is integrally formed with several limiting posts, leaving a gap between the motor housing and the PCBA. The limiting posts serve both as installation limiting posts and as a gap between the motor housing and the PCBA for air circulation and heat dissipation.

[0014] Therefore, the cooling fan controller assembly with good heat dissipation of this utility model has the following advantages: stable structure and excellent heat dissipation effect, which can effectively improve the heat dissipation of the controller, solve the problem that the current cooling fan controller is prone to overheating and performance degradation, and meet higher production requirements.
