Description

Technical Field

[0001] The invention relates to the field of an integrated water pump machine, and in particular to an integrated water pump machine with a novel heat dissipation structure. Background Art

[0002] With the development and progress of science and technology, water pumps are used as a driving machine to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. Their functions and structures are becoming more and more perfect. Controllers and motors are indispensable components of water pumps.

[0003] At present, the installation methods of controller and motor are mostly split or the controller is installed in the motor barrel. The split installation increases the cost of the water pump and occupies a large space. The controller is installed in the motor barrel. Since both the motor and the controller generate a lot of heat, the natural wind enters from the rear end of the motor, and will first pass through the drive device to consume part of the wind energy before passing through the motor part. The heat dissipation effect is not very good. The temperature of the water pump is too high after long-term use, affecting the working state of the water pump. The traditional water pump casing adopts an integrated metal casing, which has too high resonance, loud noise and vibration frequency, which will accelerate the deformation and aging of parts and shorten the life of the water pump. When the traditional water pump is hoisted, the lifting ring is located at the rear end of the motor casing. The water pump shakes violently due to strong vibration during operation, which is prone to safety accidents. Summary of the invention

[0004] The purpose of the present invention is to solve the existing problems and provide a water pump integrated machine with a novel heat dissipation structure.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A water pump integrated machine with a novel heat dissipation structure comprises a cylinder body, which is fixedly connected to a rear shell end cover, with a motor shaft extension end as the lower end, a first space and a second space connected in sequence from bottom to top in the cylinder body, a motor is fixedly installed in the first space, a blowing device is installed in the second space, the blowing device is connected to the motor shaft, a drive installation box is fixedly connected to the bottom of the cylinder body, a drive installation box is arranged in the drive installation box, the internal space enclosed by the rear shell end cover and the drive installation box forms a third space, a drive heat dissipation mechanism is fixedly installed in the third space, and the cylinder body is provided with a heat dissipation air duct.

[0007] This structural arrangement arranges the drive box and the motor in an alternating and stacked manner, making the drive installation more convenient. The drive heat dissipation mechanism can absorb the heat emitted by the drive to a greater extent. Through the scientific combination of the heat sink channel and the heat dissipation duct of the cylinder, the fan discharges the heat to protect the drive from malfunctions caused by heat generated during long-term operation.

[0008] Preferably, the driving heat dissipation mechanism includes a connecting plate, a heat sink base, a strip heat sink, a waterproof rubber ring and a fan, wherein the connecting plate is fixedly connected to the heat sink base, the heat sink base is fixedly connected to the strip heat sink, the waterproof rubber ring is fixedly connected to the heat sink base, and the fan is fixedly connected to the connecting plate.

[0009] This structure ensures normal heat dissipation of the driver part and prevents the driver from overheating and affecting the operation of the motor.

[0010] Preferably, the connecting plate is fixedly connected to a middle reinforcement plate, an edge of the middle reinforcement plate is folded from the second space toward the third space, and the middle reinforcement plate is provided with a through hole.

[0011] This structure allows the heat in the third space to be transferred to the heat dissipation channel through the through holes. The folding of the edge of the middle fixed plate allows the second space and the third space to be ventilated. The rear shell end cover is fixedly installed at the folded position.

[0012] Preferably, the strip-shaped heat sink is L-shaped, and adjacent heat sinks are spaced equidistantly from each other.

[0013] This structure dissipates the heat of the driver part through heat transfer to a greater extent.

[0014] Preferably, the heat dissipation duct includes an inner cylinder heat dissipation duct and a heat sink heat dissipation duct. The inner cylinder heat dissipation duct sequentially connects the third space, the middle reinforcement plate, the second space and the first space, is powered by a blowing device and a fan, and the heat sink heat dissipation duct is surrounded by a connecting plate and a drive mounting box.

[0015] This structure enables the heat from the driver and the motor to be discharged through the heat dissipation duct in the cylinder and the heat dissipation duct on the heat sink when the water pump is running, thus ensuring stable operation of the water pump.

[0016] Preferably, the heat dissipation air duct in the cylinder is provided with an air outlet located in the first space, and a raised strip is integrally formed around the inner wall of the cylinder, one end of the raised strip is fixed to the inner wall of the cylinder, and the other end extends and protrudes along the radial direction of the cylinder body and abuts against the motor housing, and the raised strip runs through the first space and the second space and forms an air outlet with the motor housing.

[0017] This structure allows the heat of the cylinder to pass through the gap between the cylinder shell and the motor when the water pump is in operation, so that the generated heat can enter the external space, achieving the effect of air flow.

[0018] Preferably, the cylinder is symmetrically provided with four recessed parts, and a heat sink heat dissipation duct is left between the recessed parts and the drive installation box.

[0019] This structure can directly discharge part of the heat absorbed by the driver from the heat sink through the fan at the rear, and the recessed design can increase the strength of the cylinder itself and prevent deformation.

[0020] Preferably, a pair of triangular hanging rings are fixedly connected to the outer sides of the cylinder.

[0021] This structure ensures that the motor is not prone to shaking when hoisted.

[0022] Preferably, a through hole is provided at the rear end of the rear shell end cover, and the rear shell end cover is made of ABS plastic material.

[0023] This structure maximizes the ventilation efficiency of the rear shell end cover. Using different materials can make the resonance frequency of the rear shell end cover and the cylinder different. ABS plastic has small vibration, small noise, good heat resistance and high ignition point.

[0024] In summary, the present invention has the following beneficial effects: the drive controller and the motor are integrated, the water pump integrated machine driver and the motor are arranged in a staggered stacking manner, the driver is more convenient to install, the drive heat dissipation mechanism can absorb the heat emitted by the driver to the maximum extent, and the heat dissipation duct of the cylinder is scientifically combined through the heat sink channel. The fan discharges the heat to protect the driver from failures caused by heating due to long-term operation. The heat generated by the motor is transferred to the cylinder through the raised strips, and the heat dissipation duct of the cylinder protects the motor from failures caused by heating due to long-term operation. The shell of the water pump integrated machine adopts a combination of special plastic and metal. The cylinder body is provided with a recessed portion, and a middle reinforcement plate is installed inside the body. The body has high strength and is not easy to deform. The protection level can reach IP65. The vibration frequencies of plastic and metal are different, and the vibration generated is smaller. It is not easy to make the parts of the water pump integrated machine loose and aged, and the noise is smaller. The installation rings are arranged on both sides of the water pump integrated machine, which is conducive to maintaining balance during lifting operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0032] Reference Figure 1 , Figure 2A water pump integrated machine with a new heat dissipation structure includes a cylinder, a cylinder 1 is fixedly connected to a rear shell end cover 2, and the motor shaft extension end is the lower end. The cylinder 1 is connected with a first space 3 and a second space 4 from bottom to top in sequence. A motor 5 is fixedly installed in the first space 3, and a blowing device 6 is installed in the second space 4. The blowing device 6 is connected to the motor 5 shaft. A drive installation box 7 is fixedly connected to the bottom of the cylinder 1, and a drive controller 8 is arranged in the drive installation box 7. The inner space enclosed by the rear shell end cover 2 and the drive installation box 7 forms a third space 9. A drive heat dissipation mechanism 10 is fixedly installed in the third space 9. The body 1 is provided with a heat dissipation duct 11, and the driving heat dissipation mechanism 10 includes a connecting plate 10-1, a heat sink base 10-2, a strip heat sink 10-3, a waterproof rubber ring 10-4 and a fan 10-5. The connecting plate 10-1 is fixedly connected to the heat sink base 10-2, the heat sink base 10-2 is fixedly connected to the strip heat sink 10-3, the waterproof rubber ring 10-4 is fixedly connected to the heat sink base 10-2, the fan 10-5 is fixedly connected to the connecting plate 10-1, and the connecting plate 10-1 is fixedly connected to the middle reinforcement plate 12. The edge of the middle reinforcement plate 12 is extended from the second space 4 to the third space 9. The heat sink 10-3 is L-shaped, and adjacent heat sinks are spaced equidistantly. The heat dissipation duct 11 includes a heat dissipation duct 13 in the cylinder and a heat dissipation duct 14 for the heat sink. The heat dissipation duct 13 in the cylinder sequentially connects the third space 9, the middle reinforcement plate 12, the second space 4 and the first space 3, and is powered by the blowing device 6 and the fan 10-5. The heat dissipation duct 14 for the heat sink is surrounded by the connecting plate 10-1 and the drive installation box 7. The heat dissipation duct 13 in the cylinder is provided with an air outlet 13-1 located in the first space 3. The inner wall of the cylinder 1 is integrally formed with a protrusion. Strip 13-2, one end of the raised strip 13-2 is integrally formed on the inner wall of the cylinder 1, and the other end extends and protrudes along the radial direction of the cylinder 1 body and abuts against the motor 5 housing. The raised strip 13-2 passes through the first space 3 and the second space 4 and the motor 5 housing to form an air outlet 13-1. The cylinder 1 is symmetrically provided with four recessed portions 15, and a heat sink cooling duct 14 is left between the recessed portions 15 and the drive installation box 7. A cover plate is provided at the bottom of the drive installation box 7, and a pair of triangular hanging rings 16 are fixedly connected to both sides of the outside of the cylinder 1. A through hole is provided at the tail of the rear shell end cover 2, and the rear shell end cover 2 and the drive installation box 7 are made of ABS plastic.

[0033] More specifically, when the water pump all-in-one is working, the motor 5 and the drive controller 8 are the main components that generate heat in the machine body itself. The drive controller 8 is installed in the drive mounting box 7, and the drive mounting box 7 is fixedly connected to the drive heat dissipation mechanism 10. The waterproof rubber ring 10-4 fits the heat sink base 10-2, which can prevent water vapor from entering the interior of the machine body through the mounting hole. The heat generated by the drive controller 8 will be transferred to the drive heat dissipation mechanism 10. The heat sink base 10-2 of the drive heat dissipation mechanism 10 is fixedly connected to the strip heat sink 10-3, which can maximize the heat conduction of the drive controller 8 to the strip heat sink 10-3. The L-shaped design of the strip heat sink can not only enable the strip heat sink 10-3 to utilize the extra internal space of the second space of the machine body and maximize the use of the internal space of the machine body, but also increase the heat dissipation capacity of the strip heat sink 10-3, thereby maximizing the dissipation of the heat generated by the drive controller 8. The connecting plate 10 - 1 can position and install components such as the fan 10 - 5 and can also transfer the heat of the strip heat sink 10 - 3 to the third space 9 and discharge it through the fan 10 - 5 and the blowing device 6 .

[0034] The heat dissipation duct 13 in the cylinder is connected to the third space 9, the middle reinforcement plate 12, the second space 4 and the first space 3 in sequence, and is powered by the blowing device 6 and the fan 10-5. The heat dissipation duct 13 in the cylinder is provided with an air outlet 13-1 and a raised strip 13-2. The middle reinforcement plate 12 is not only used as a connecting piece to install the rear shell end cover 2 and the cylinder 1, but also can enhance the strength of the water pump all-in-one machine and is not easy to deform. The driving heat dissipation mechanism 10 is also fixedly installed on the middle reinforcement plate 12 for fixing and positioning. The middle reinforcement plate 12 is provided with a through hole and the edge is folded, so that the second space 4 and the third space 9 form an air flow channel, so that the heat generated by the third space 9 driving the heat dissipation mechanism 10 flows to the second space 4 through the middle reinforcement plate 12. The second space 4 motor 5 shaft is installed with a blowing device 6, which can form a pressure difference to drive the airflow of the third space 9 through the middle reinforcement plate 12 to the second space 4 and then through the air outlet 13-1 of the first space 3 to send the heat to the outside.

[0035] The heat sink cooling air duct 14 is surrounded by the connecting plate 10-1 and the drive installation box 7. The cylinder is provided with four symmetrical recessed portions 15, so that a heat sink cooling air duct 14 exists between the cylinder 1 and the drive installation box 7. The fan 10-5 driving the heat dissipation mechanism 10 will discharge part of the heat of the strip heat sink 10-3 directly from the heat sink cooling air duct 14, and the other part of the heat will be discharged through the cooling air duct 13 in the cylinder. The recessed portion 15 can also enhance the strength of the cylinder itself and is not easily deformed.

[0036] The drive installation box 7 and the rear shell end cover 2 are made of ABS plastic material. ABS has the common properties of three components. A represents chemical corrosion resistance, heat resistance, and a certain surface hardness. B represents high elasticity and toughness. S represents the processing and molding characteristics of thermoplastics and improves electrical properties. Therefore, ABS plastic is a tough, hard, and rigid material with easy-to-obtain raw materials, good comprehensive performance, low price, and wide application. The resonance frequency of the upper and lower parts is different, the vibration frequency of the plastic is lower, the vibration is small, and the noise is small. 45° triangular lifting rings are installed on both sides, which is conducive to the balance of the lifting operation. The drive control box 7 and the motor 5 of the whole machine are arranged in an integrated staggered stacking manner. The drive heat dissipation mechanism 10 is organically combined with the motor 5 part. The heat dissipation efficiency of the whole machine is improved through a scientific heat dissipation duct. While the work efficiency is improved, more installation space is saved.

[0037] The beneficial effects of the present application are as follows: the drive controller and the motor are integrated, the water pump integrated machine driver and the motor are arranged in a staggered stacking manner, the driver is more convenient to install, the drive heat dissipation mechanism can absorb the heat emitted by the driver to the maximum extent, and the heat dissipation duct of the cylinder is scientifically combined through the heat sink channel. The fan discharges the heat to protect the driver from failures caused by heating due to long-term operation. The heat generated by the motor is transferred to the cylinder through the raised strips, and the heat dissipation duct of the cylinder protects the motor from failures caused by heating due to long-term operation. The shell of the water pump integrated machine adopts a combination of special plastic and metal. The cylinder body is provided with a recessed part, and a middle reinforcement plate is installed inside the body. The body has high strength and is not easy to deform. The protection level can reach IP65. The vibration frequencies of plastic and metal are different, and the vibration generated is smaller. It is not easy to make the parts of the water pump integrated machine loose and aging, and the noise is smaller. The installation rings are set on both sides of the water pump integrated machine, which is conducive to maintaining balance during lifting operation.
