Description

Technical Field

[0001] This application relates to the technical field of water pumps, and particularly to a water pump housing structure with external heat dissipation for the transmission element, which takes into account both functionality and heat dissipation, optimizes the water flow path, and improves the overall performance and service life of the water pump. Background Art

[0002] As a key device for liquid transportation or circulation, water pumps are widely used in various industrial, agricultural, and domestic fields. Among them, the design of the water pump housing has an important impact on the performance and service life of the water pump.

[0003] Currently, most water pump housings on the market focus on functionality, but relatively little consideration is given to heat dissipation performance. As the water pump operates for a long time, if the heat generated inside cannot be dissipated in time, it will affect the working efficiency and service life of the water pump.

[0004] Traditional water pump housing designs often neglect the optimization of the heat dissipation structure, or only have simple heat dissipation structures set at local positions, unable to effectively dissipate the heat generated inside in time. In addition, there are also certain limitations in the structural design of existing water pump housings. For example, the settings of the inlet and outlet positions are unreasonable, resulting in an unsmooth water flow path, which further affects the heat dissipation effect. Therefore, how to balance functionality and heat dissipation in the design of the water pump housing and improve the overall performance and service life of the water pump has become an urgent problem to be solved. Utility Model Content

[0005] The purpose of this application is to overcome the above technical problems and provide a water pump housing structure with external heat dissipation for the transmission element, which takes into account both functionality and heat dissipation, optimizes the water flow path, and improves the overall performance and service life of the water pump.

[0006] This application provides a water pump housing structure with external heat dissipation for the transmission element, including: a first housing and a second housing that are relatively closed. Integral heat dissipation fins are provided on the outer sides of both the first housing and the second housing. An inlet and an outlet are provided on the outer side of the first housing. The inlet is provided on the end face of the first housing away from the second housing, and the outlet is provided on the side of the first housing close to the second housing.

[0007] By adopting the above technical solution, integral heat dissipation fins are provided on the outer sides of both the first housing and the second housing. These fins can effectively dissipate the heat generated during the operation of the water pump, thereby improving the working efficiency and service life of the water pump. An inlet and an outlet are provided on the outer side of the first housing. The inlet is provided on the end face of the first housing away from the second housing, and the outlet is provided on the side of the first housing close to the second housing. Such a design makes the water flow path more reasonable, which helps to improve the circulation efficiency of the water flow and the heat dissipation effect.

[0008] Optionally, a space for accommodating the rotor is formed between the first housing and the second housing, and the inner wall of the second housing is designed in a U shape. One end face opposite to the first housing forms a first U-shaped groove for the magnets of the rotor to rotate, and the other end face of the second housing away from the first housing forms a second U-shaped groove for accommodating the driving member for driving the magnets to rotate.

[0009] By adopting the above technical solution, through the inner wall of the second housing designed in a U shape, the water pump can make more efficient use of the internal space, making the layout of key components such as the rotor, magnets and driving member more reasonable. This not only improves the operating efficiency of the water pump, but also facilitates heat dissipation.

[0010] Optionally, extension pipes are respectively arranged at the water inlet and the water outlet.

[0011] By adopting the above technical solution, extension pipes are respectively connected at the water inlet and the water outlet, which can be conveniently connected to external pipes, improving the installation and use convenience of the water pump. At the same time, the design of the extension pipes also helps to reduce the resistance of the water flow at the inlet and outlet, improving the smoothness of the water flow.

[0012] Optionally, a plurality of convex edges are arranged on the periphery of the extension pipe.

[0013] By adopting the above technical solution, a plurality of convex edges are arranged on the periphery of the extension pipe, which can increase the surface area of the extension pipe, thereby improving the heat dissipation effect. At the same time, the design of the convex edges also helps to enhance the structural strength of the extension pipe, improving the durability of the water pump. In addition, the connection stability between the extension pipe and the external pipe is also improved.

[0014] Optionally, a spacer is arranged inside one end face of the second housing away from the first housing and is located in the second U-shaped groove.

[0015] By adopting the above technical solution, on the one hand, the setting of the spacer can prevent the driving member from generating excessive vibration or noise during operation, improving the operating stability and service life of the water pump. On the other hand, it can space the multiple coils arranged on the driving member to avoid interference between the coils, thereby improving the working efficiency and stability of the driving member.

[0016] Optionally, fixing members are arranged on the side of the first housing, fixing members are arranged on the side opposite to the second housing, fixing holes are arranged on the side of the fixing member opposite to the second housing, and through holes corresponding to the fixing holes are arranged on the second housing.

[0017] By adopting the above technical solution, the screw member can be screwed into the fixing hole through the through hole to firmly cover the first housing and the second housing together, facilitating the assembly and disassembly maintenance of the two.

[0018] Optionally, the end face of the first housing abutting against the second housing is a convex edge.

[0019] By adopting the above technical solution, the end face of the first housing abutting against the second housing is set as a convex edge to increase the abutting area between the two, so as to improve the assembly firmness between the two and achieve the effect of preventing water leakage at the same time.

[0020] Optionally, the first housing and the second housing are plastic housings.

[0021] By adopting the above technical solution, the setting of the plastic housing can reduce the overall weight of the water pump, and its material has the characteristic of corrosion resistance, which can extend the service life of the housing.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1.

[0030] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of the present application, the singular forms "a", "an", "the above", "the", and "this" are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more of the listed items.

[0031] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and should not be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0032] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0033] See Figure 1 and Figure 2 As shown in and, a heat-dissipating external rotor water pump housing structure disclosed in an embodiment of the present application includes a first housing 10 and a second housing 20 that are relatively covered. Integral heat-dissipating fins 30 are provided on the outer sides of both the first housing 10 and the second housing 20, and these fins can effectively dissipate the heat generated during the operation of the water pump, thereby improving the working efficiency and service life of the water pump.

[0034] Wherein, a water inlet 11 and a water outlet 12 are provided on the outer side of the first housing 10, and a space for accommodating the rotor is formed between the first housing 10 and the second housing 20. The water inlet 11 is provided on the end face of the first housing 10 away from the second housing 20, and the water outlet 12 is provided on the side face of the first housing 10 close to the second housing 20. Such a design makes the water flow path more reasonable and helps to improve the water flow circulation efficiency and heat dissipation effect.

[0035] Accordingly, the corresponding working principle is as follows: When the water pump works, water enters the space formed by the first housing 10 and the second housing 20 from the water inlet 11, circulates under the action of the rotor, and then flows out from the water outlet 12. During this process, since integral heat-dissipating fins 30 are provided on the outer sides of both the first housing 10 and the second housing 20, the heat generated during the operation of the water pump can be timely dissipated through these fins, thereby maintaining the normal working temperature of the water pump and improving the working efficiency and service life.

[0036] See Figure 2 and Figure 3, a fixing member 14 is provided on the side of the first housing 10, a fixing member 14 is provided on the side opposite to the second housing 20, a fixing hole 141 is provided on the side of the fixing member 14 opposite to the second housing 20, and a through hole 24 is provided on the second housing 20 corresponding to the fixing hole 141.

[0037] Among them, the through hole 24 is a hole penetrating the side of the second housing 20, so that a screw can penetrate through the through hole 24 and be screwed into the fixing hole 141 to firmly cover the first housing 10 and the second housing 20 together, facilitating the assembly and disassembly maintenance of the two.

[0038] Furthermore, the edges where the first housing 10 and the second housing 20 are in contact are set as convex edges, which can increase the contact area between the two, and while increasing the firmness of their assembly, it can achieve the effect of preventing water leakage.

[0039] In addition, the first housing 10 and the second housing 20 are set as plastic housings, which can reduce the overall weight of the water pump, and the plastic housings have the characteristics of corrosion resistance, which can extend the service life of the housings.

[0040] See Figure 2 , the inner wall of the second housing 20 is designed in a U shape, and a first U-shaped groove 21 is formed at one end face opposite to the first housing 10, which is used for the rotation and accommodation of the magnetic steel of the rotor. See Figure 3 , and a second U-shaped groove 22 is formed at the end face of the second housing 20 far from the first housing 10, which is used for accommodating the driving member for driving the rotation of the magnetic steel. Such a design makes the internal structure of the water pump more compact and reasonable, and is also beneficial to heat dissipation and maintenance.

[0041] Among them, when the water pump works, the magnetic steel of the rotor rotates in the first U-shaped groove 21, and the driving member works in the second U-shaped groove 22 to jointly drive the operation of the water pump. At the same time, due to the optimization of the internal structure, the heat dissipation performance of the water pump is further improved.

[0042] Furthermore, extension pipes 13 are respectively provided at the water inlet 11 and the water outlet 12. The setting of the extension pipes 13 can facilitate the connection of the water pump with external pipelines, thereby improving the installation and use convenience of the water pump.

[0043] Among them, by setting the extension pipes 13, the water pump can be more flexibly connected with external pipelines to adapt to the use requirements in different scenarios. When the water pump works, water flows in from the extension pipe 13 of the water inlet 11, and after circulating inside the water pump, it flows out from the extension pipe 13 of the water outlet 12, so as to reduce the resistance of the water flow at the inlet and outlet, improve the smoothness of the water flow, and thus improve the working efficiency of the water pump.

[0044] Furthermore, a plurality of convex edges 131 are provided on the circumferential side of the extension pipe 13 to increase the surface area of the extension pipe 13, thereby improving the heat dissipation effect.

[0045] Among them, when the water pump works, water flows in and out through the extension pipe 13. Since the convex edges on the circumferential side of the extension pipe 13 increase the surface area, the contact area between the water flow and the pipe wall is increased, thereby improving the heat exchange efficiency. At the same time, the convex edges also act as reinforcing ribs, enhancing the structural strength of the extension pipe 13 and preventing deformation or damage caused by water flow impact. In addition, the connection stability between the extension pipe 13 and the external pipeline is also improved.

[0046] See Figure 3 , a plurality of spacer pieces 23 are provided on the end face of the second housing 20 away from the first housing 10. These spacer pieces 23 are located in the second U-shaped groove 22 and surround the second U-shaped groove 22, and are used to support and fix the driving member to prevent the driving member from generating excessive vibration or noise during operation, and improve the operating stability and service life of the water pump.

[0047] In addition, these spacer pieces 23 can space the plurality of coils provided on the driving member to avoid interference between the coils, thereby improving the working efficiency and stability of the driving member.

[0048] In summary, for a heat dissipating external rotor water pump housing structure disclosed in an embodiment of the present application, by providing integral heat dissipation fins 30 on the outer sides of both the first housing 10 and the second housing 20, these fins can effectively dissipate the heat generated during the operation of the water pump, thereby improving the working efficiency and service life of the water pump; an inlet 11 and an outlet 12 are provided on the outer side of the first housing 10. The inlet 11 is provided on the end face of the first housing 10 away from the second housing 20, and the outlet 12 is provided on the side face of the first housing 10 close to the second housing 20. Such a design makes the water flow path more reasonable, which helps to improve the water flow circulation efficiency and heat dissipation effect.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. For those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present application.
