Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to a water-cooled motor casing that reduces the temperature rise of a water pump. Background Art

[0002] When the water pump is working, the water pump itself generally generates heat. In order to ensure the long-term stable operation of the water pump, the water pump is usually cooled. This work usually uses a water-cooled motor casing to achieve heat exchange with the water pump inside the casing, thereby achieving cooling of the water pump.

[0003] According to a publicly disclosed casing for reducing the temperature rise of a motor (publication number: CN208461604U), in the above application, a spiral water channel structure is adopted, the water inlet and the water outlet are connected to the external water pipe, and the external cooling water quickly dissipates the heat generated by the motor through the spiral water channel in the casing. At the same time, the heat dissipation fins on the surface of the casing can also accelerate the heat dissipation of the motor.

[0004] However, during actual use of the above-mentioned equipment, the heat dissipation structure of the spiral water channel realizes heat transfer through the cooling water continuously flowing inside it. However, when the cooling water flows in the spiral water channel, the cooling water at the center of the spiral water channel and the cooling water near the spiral water channel wall have different degrees of heat exchange, and the cooling water flows at a faster speed, which makes the cooling efficiency of the spiral water channel for the motor casing subject to certain limitations; in view of this, we propose a water-cooled motor casing that reduces the temperature rise of the water pump.

[0006] To achieve the above object, the utility model provides the following technical solution: a water-cooled motor casing for reducing the temperature rise of a water pump, comprising a casing, a heat dissipation fin is fixedly mounted on the arc-shaped outer wall of the casing, a heat dissipation component is arranged on the inner wall of the casing, and the heat dissipation component comprises:

[0011] Preferably, the number of the connecting nozzles is two groups, and the two groups of connecting nozzles are respectively arranged at two ends of the spiral water channel, and the connecting nozzles are connected to the spiral water channel.

[0012] Preferably, the bottom arc-shaped outer wall of the curved soft belt is matched with the arc-shaped inner surface of the spiral water channel, so that the curved soft belt can maintain good fit when arranged in the spiral water channel.

[0013] Preferably, the number of the spoiler fins is arranged in several groups, and the several groups of spoiler fins are evenly distributed on the left and right outer walls of the triangular band, and the spoiler fins are arranged in an inclined state, so that when the cooling water in the spiral water channel passes through the spoiler fins during the flow process, the spoiler fins will guide the cooling water to move toward the center of the spiral water channel.

[0014] Preferably, the magnetic belt is matched with the embedded groove, and the magnetic belt is arranged in a T-shape, and the bottom end surface of the magnetic belt is arranged in an arc shape to adapt to the installation of the curved soft belt in the spiral waterway.

[0018] 1. The water-cooled motor housing for reducing the temperature rise of the water pump is provided with a heat dissipation component, which cooperates with the curved soft belt and the curved soft belt arranged in the spiral water channel. Under the guidance of the obliquely arranged spoiler fins, the cooling water at the center of the spiral water channel flows toward the inner surface of the spiral water channel. Since the curved soft belt is spirally arranged in the spiral water channel, the cooling water is prompted to move in a spiral manner when flowing, ensuring that the cooling water is continuously mixed, so that its temperature is in a relatively balanced state, thereby ensuring the continuous cooling effect of the spiral water channel and the cooling water on the housing.

[0019] 2. The water-cooled motor casing for reducing the temperature rise of the water pump has curved bristles on both sides of the curved water belt. The staff can regularly pull out the curved soft belt and cooperate with the movement of the bristles on the inner surface of the spiral water channel to brush and clean the inner wall of the spiral water channel, thereby preventing scale or other impurities generated in the spiral water channel due to long-term use from affecting the natural flow of cooling water, thereby reducing the heat dissipation effect of the device on the casing.

[0027] Furthermore, the number of heat dissipation fins 2 is set to multiple groups, and the multiple groups of heat dissipation fins 2 are evenly distributed in a circular array on the arc-shaped outer surface of the shell 1, thereby increasing the contact area between the shell 1 and the external environment, thereby effectively improving the cooling effect of the shell 1. At the same time, the number of connecting nozzles 31 is set to two groups, and the two groups of connecting nozzles 31 are respectively arranged at both ends of the spiral water channel 32. Specifically, the connecting nozzles 31 are through-connected with the spiral water channel 32. When in use, they are connected to the two groups of connecting nozzles 31 respectively through an external circulation pipe, and the external circulation pipe is connected to the circulation pump and the cooling water cooling pool. At this time, when the circulation pump is started, the cooling water continuously flows inside the shell 1 in cooperation with the external circulation pipe, the cooling water cooling pool, the connecting nozzles 31 and the spiral water channel 32 to continuously take away the heat inside the shell 1, so as to achieve cooling of the shell 1 and ensure that the water pump arranged inside the shell 1 is continuously in good working condition.

[0028] In addition, the bottom arc-shaped outer wall of the curved soft belt 33 is adapted to the arc-shaped inner surface of the spiral water channel 32, so that the curved soft belt 33 can maintain good fit when it is set in the spiral water channel 32. At the same time, the triangular belt 34 is set at the center of the curved soft belt 33, and the curved soft belt 33 and the triangular belt 34 are both made of silicone material. While improving the flexibility of the curved soft belt 33 and the triangular belt 34, the wear of the curved soft belt 33 and the triangular belt 34 caused by the continuous flow of cooling water is reduced, thereby reducing the possibility of residual impurities in the spiral water channel 32. Specifically, the number of spoiler fins 35 is set in several groups, and the several groups of spoiler fins 35 are evenly distributed on the left and right outer walls of the triangular belt 34, and the spoiler fins 35 are arranged in an inclined shape, so that the spiral water channel When the cooling water in 32 passes through the spoiler fins 35 during the flow process, the spoiler fins 35 will guide the cooling water, so that the cooling water at the center of the spiral water channel 32 flows toward the inner surface of the spiral water channel 32, and through the flow of the cooling water itself, the cooling water itself will also mix when it flows, ensuring that the temperature of the cooling water is in a relatively balanced state, thereby ensuring the continuous cooling effect of the spiral water channel 32 and the cooling water on the shell 1. Furthermore, the curved soft belt 33 is spirally arranged in the spiral water channel 32, so that the cooling water in the inner wall of the spiral water channel 32 moves in a spiral manner when flowing, thereby improving the mixing and intersection effect of the cooling water in the spiral water channel 32, thereby ensuring the cooling effect of the cooling water on the spiral water channel 32 and the shell 1.

[0030] Specifically, the bristles 38 are made of metal wires, and the bristles 38 are arranged in multiple curved sections on the left and right sides of the curved soft belt 33, so that the staff can regularly pull out the curved soft belt 33 and cooperate with the movement of the bristles 38 on the inner surface of the spiral water channel 32 to brush and clean the inner wall of the spiral water channel 32, thereby avoiding scale or other impurities generated in the spiral water channel 32 due to long-term use to affect the natural flow of cooling water, thereby reducing the heat dissipation effect of the device on the shell 1.

[0031] In the utility model, when in use, the connecting nozzle 31 is connected to the circulation pump and the external cooling water cooling pool through the external circulation pipe. When the water pump in the shell 1 is in use, the circulation pump is started, so that the cooling water filled in the circulation pipe and the spiral water channel 32 begins to flow, so as to continuously take away the heat inside the shell 1, thereby realizing the continuous cooling of the water pump inside the shell 1. At the same time, by providing a heat dissipation component 3, cooperating with the curved soft belt 33 and the curved soft belt 33 provided in the spiral water channel 32, under the guidance of the inclined spoiler fins 35, the cooling water at the center of the spiral water channel 32 flows toward one side of the inner surface of the spiral water channel 32, and because the curved soft belt 33 is spirally arranged in the spiral water channel 32, the cooling water is prompted to move in a spiral manner when flowing, ensuring that the cooling water is continuously mixed, so that its temperature is in a relatively balanced state, thereby ensuring the continuous cooling effect of the spiral water channel 32 and the cooling water on the shell 1.
