Description

Technical Field

[0001] This utility model relates to the field of automotive water pumps, and in particular to an automotive water pump with a heat dissipation function. Background Technology

[0002] The cooling system plays a crucial role in the operation of a car engine, and the water pump, as a core component of the cooling system, directly affects the engine's heat dissipation efficiency and operational stability. The main function of the water pump is to drive the coolant to circulate between components such as the engine water jacket and radiator, dissipating the large amount of heat generated during engine operation through heat exchange, ensuring that the engine always operates within a suitable temperature range.

[0003] The existing technology has the following problems: The heat dissipation of the car water pump under the existing technology mainly relies on the natural flow of coolant in the cooling system and air convection in the engine compartment. This passive heat dissipation method has low heat dissipation efficiency. When the car is in conditions such as long-term high-speed driving or climbing hills, the heat generated by the engine increases significantly, and the temperature in the engine compartment rises sharply. At this time, the heat generated by the water pump itself and the heat transferred from the surrounding environment cannot be dissipated in time, which can easily lead to the water pump temperature becoming too high.

[0004] Prolonged operation of a water pump in a high-temperature environment will accelerate the aging of the internal seals, leading to coolant leakage, affecting the normal operation of the cooling system, and high temperature will reduce the working efficiency and service life of the motor, and may even cause motor burnout and other malfunctions.

[0005] Therefore, we propose a car water pump with heat dissipation function to solve the above problems. Utility Model Content

The inner wall of the heat dissipation inner cylinder is in contact with the outer surface of the electronic water pump to conduct heat. A fan is fixedly installed at the tail end of the outer shell, and the fan is electrically connected to the car power supply.

[0013] This utility model features a heat dissipation structure, which is fixed to the car's engine compartment via a mounting base. The heat dissipation structure includes an outer shell, a heat dissipation inner cylinder, and a fan, forming an active heat dissipation structure. The inner wall of the heat dissipation inner cylinder is in direct contact with the outer surface of the electronic water pump, which can quickly conduct the heat generated by the water pump to the heat conduction cylinder and the outer heat dissipation fins.

Detailed Implementation

[0023] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0024] like Figure 1 , 2 As shown, this utility model provides a car water pump with heat dissipation function, including an electronic water pump 1. The main function of the electronic water pump 1 is to drive the coolant to circulate between components such as the engine water jacket and radiator. This component is a known technology and will not be described in detail. The heat dissipation structure 2 is used to dissipate heat for the electronic water pump 1 to prevent it from malfunctioning or being damaged due to high temperature. The heat dissipation structure 2 is installed in the car engine compartment through the mounting base 3, so that the heat dissipation structure 2 can cooperate with the electronic water pump 1 to dissipate heat. At the same time, the mounting base 3 can more firmly install the heat dissipation structure 2 and the electronic water pump 1 in the car engine compartment, effectively improving the installation stability. The heat dissipation structure 2 is fixedly installed on the top of the mounting base 3, and the electronic water pump 1 is embedded inside the heat dissipation structure 2.

[0025] like Figure 3 , 4As shown, this utility model includes a heat dissipation structure 2, which includes an outer shell 21 and a heat dissipation inner cylinder 22. The outer shell 21 is fixedly installed on the top of the mounting base 3. The outer shell 21 is used for installation and connection, and can also provide a certain degree of protection for the electronic water pump 1, reducing the damage to the electronic water pump 1 caused by external impact. The interior of the outer shell 21 is an axially penetrating hollow structure, which can provide an installation position for the heat dissipation inner cylinder 22. The heat dissipation inner cylinder 22 is fixedly assembled inside the outer shell 21, and the electronic water pump 1 is fixedly embedded inside the heat dissipation inner cylinder 22. The inner wall of the heat dissipation inner cylinder 22 is in contact with the outer surface of the electronic water pump 1 to conduct heat. In this specific embodiment... The heat dissipation inner cylinder 22 and the electric water pump 1 are fixedly connected by an interference fit. The pressure generated by the interference fit firmly fixes the two together, avoiding relative displacement caused by vibration during vehicle operation. It also makes the two fit more closely, maximizing their contact area and significantly reducing the thermal resistance of heat conduction. A fan 23 is fixedly installed at the tail end of the outer shell 21. The fan 23 is electrically connected to the vehicle's power supply. When the electric water pump 1 is running and dissipating heat, the heat will be transferred through the outer surface of the electric water pump 1 to the heat dissipation inner cylinder 22. The fan 23 will drive air circulation to carry away the heat from the heat dissipation inner cylinder 22, thereby achieving the effect of cooling the electric water pump 1.

[0026] like Figure 5 , 6 As shown, the heat dissipation inner cylinder 22 of this utility model includes a heat-conducting cylinder 221, in which an electronic water pump 1 is fixedly embedded. The inner wall of the heat-conducting cylinder 221 is in contact with the outer surface of the electronic water pump 1. The heat-conducting cylinder 221 and the electronic water pump 1 are fixedly connected by an interference fit. It should be noted that, in order to avoid damage to the internal components of the electronic water pump 1 during the interference fit assembly, the heat-conducting cylinder 221 is made of aluminum alloy with excellent thermal conductivity, which has a certain elastic deformation capability. During the press-fitting process, it can buffer the assembly stress through its own deformation. The outer surface of the heat-conducting cylinder 221 is provided with heat sinks 222 in a ring array. In this embodiment, the heat sinks adopt a long strip thin plate structure and are arranged in a ring array. When the heat from the electric water pump 1 is transferred to the heat sink 222 through the heat conduction cylinder 221, more heat can be quickly exchanged with the surrounding air through the heat sink 222. With the airflow driven by the fan 23, the heat is dissipated from the surface of the heat sink 222, which significantly improves the heat dissipation efficiency. The outer surface of the heat conduction cylinder 221 is symmetrically provided with mounting blocks 223. The mounting position of the mounting blocks 223 avoids the heat sink 222. The end of the mounting block 223 away from the heat conduction cylinder 221 is fixedly connected to the inner wall of the outer shell 21. The heat conduction cylinder 221 is fixedly assembled in the inner wall of the outer shell 21 through the mounting blocks 223. The mounting blocks 223 are used for installation and connection, and the mounting blocks 223 can be fixed to the outer shell 21 and the heat conduction cylinder 221 by welding.

[0027] Among them, the outer ring array of the outer shell 21 has heat dissipation holes 211 through it. The heat dissipation holes 211 are connected to the hollow structure inside the outer shell 21. When the fan 23 is working, it will drive the air inside the outer shell 21 to flow. The hot air will move towards the side wall of the outer shell 21 under the push of the air flow and be discharged to the outside of the outer shell 21 through the heat dissipation holes 211. At the same time, the airflow when the car is moving will supplement the interior of the outer shell 21 through some of the heat dissipation holes 211, forming an air circulation and accelerating the dissipation of heat.

[0028] There is a gap between the outer end of the heat sink 222 and the inner wall of the outer casing 21, and the gap is not less than 0.2cm. The gap ensures that the airflow can flow smoothly between the heat sink 222 and the outer casing 21, so that the heat on the surface of the heat sink 222 can be quickly removed, improving the heat dissipation efficiency. When the car is moving, the external airflow flows over the surface of the outer casing 21 and enters the gap through the heat dissipation hole 211. It works together with the airflow driven by the fan 23 to further enhance the airflow speed and accelerate the heat dissipation.

[0029] like Figure 7 As shown, the mounting base 3 of this utility model includes a base 31. Fixing bolts 32 are installed through the four corners of the bottom of the base 31, and the base 31 is detachably installed in the car's engine compartment via the fixing bolts 32, facilitating subsequent maintenance and replacement. A mounting bracket 33 is fixedly installed at the center of the top of the base 31. The outer shell 21 is embedded in the inner groove of the mounting bracket 33. In this embodiment, the mounting bracket 33 consists of two "U"-shaped plates. During installation, the outer shell 21 is pressed into the inner groove of the mounting bracket 33, gradually entering the inner groove. As the outer shell 21 continues to penetrate, it compresses the two side walls of the "U"-shaped plates. The two side walls of the "U"-shaped plates, after being compressed, will extend outward, producing elastic deformation, and the groove width will increase accordingly until the middle of the outer shell 21 is completely embedded in the groove. At this point, the external force is released, and the two side walls of the "U"-shaped plates, due to their own elasticity, return to their original shape, contract inward, and tightly adhere to the outer side wall of the outer shell 21. The elastic rebound force of the two side walls firmly clamps the outer shell 21.

[0030] Working principle: When the electric water pump 1 generates heat during operation, it is tightly contacted with the heat-conducting cylinder 221 through an interference fit, and the heat is transferred to the heat-conducting cylinder 221. The heat in the heat-conducting cylinder 221 is quickly conducted to the heat sink 222 of the outer ring array. The heat sink 222 expands the heat dissipation area with its large area structure. At the same time, the heat-conducting cylinder 221 is fixed to the inner wall of the outer shell 21 by symmetrically arranged mounting blocks 223. The mounting blocks 223 avoid the heat sink 222 and do not affect heat dissipation. They can also conduct some heat to the outer shell 21. The fan 23 at the tail end of the outer shell 21 is connected to the car power supply and started, driving the air inside the outer shell 21 to flow. The airflow flows through the gap between the heat sink 222 and the gap between the outer end of the heat sink 222 and the inner wall of the outer shell 21. After heat exchange with the heat sink 222, it carries heat and is discharged through the heat dissipation holes 211 of the outer ring array on the outer side of the outer shell 21. When the car is moving, the external airflow enters the interior of the outer shell 21 through the heat dissipation holes 211, forming an air circulation to accelerate heat dissipation.

[0031] The entire structure is fixed by the mounting base 3. The base 31 is installed in the car engine compartment by the fixing bolts 32 at the four corners of the bottom. The mounting bracket 33 at the top center is a "U" shaped plate. When the outer shell 21 is squeezed into its inner groove, the two sides of the "U" shaped plate extend outward. After being inserted, it returns to its original shape and clamps the outer shell 21 to ensure the stability of the heat dissipation structure 2 and the electronic water pump 1.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
