Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pumps, in particular to a filling magnetic pump with a cooling mechanism. Background Art

[0002] When the magnetic pump and the motor are running at high speed, the internal temperature will become higher and higher. The existing method is to open multiple heat dissipation holes on the outer shell to dissipate heat. However, if there is no perfect cooling structure, the heat will be slowly dissipated during use and will still accumulate inside the shell, which will reduce the service life of the magnetic pump.

[0003] To solve the above problems, there is a solution of a filling magnetic pump with a cooling mechanism (Announcement No. CN218780503U). By opening the liquid inlet plug, the coolant can be filled into the filling chamber. The coolant can cool the magnetic pump and dissipate heat through the heat dissipation holes, which can improve the cooling efficiency and achieve the purpose of protecting the magnetic pump and the motor.

[0004] However, the above scheme adopts the method of directly filling coolant to cool the magnetic pump, which has certain volume requirements for the magnetic pump and will increase the size and weight of the magnetic pump. In addition, when the magnetic pump continues to work, the temperature of the coolant will gradually rise. When the temperature of the coolant approaches the temperature at which the magnetic pump generates heat, the cooling effect on the magnetic pump will be greatly reduced, and the magnetic pump cannot be cooled continuously. Utility Model Content

[0005] The purpose of the utility model is to provide a filling magnetic pump with a cooling mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: a filling magnetic pump with a cooling mechanism, comprising a base, a motor is installed on the base, a magnetic pump head is installed on the motor, the magnetic pump head has a discharge pipe, the discharge pipe is connected with a discharge head and a return head, and liquid cooling is performed for the magnetic pump head and the motor through the discharge head, so that the magnetic pump head and the motor can be circulated and cooled;

[0007] A cooling shell, which is sleeved on the outside of the magnetic pump head. The upper and lower surfaces of the cooling shell are respectively connected with a liquid discharge head and a liquid inlet head. When the liquid transported by the magnetic pump enters the cooling shell, the heat of the cooling shell is transferred to the liquid, so that the magnetic pump head can be heat-conducted;

[0008] A cooling pipe is coiled on the surface of the motor, and two ends of the cooling pipe are respectively connected to the discharge head and the return head. A heat-conducting shell is sleeved on the surface of the cooling pipe, and the heat-conducting shell is located outside the motor. The cooling pipe and the heat-conducting shell are used to actively and passively dissipate heat for the motor, thereby improving the stability of the motor operation and preventing the motor from overheating.

[0009] Furthermore, a one-way discharge valve and a one-way reflux valve are installed on the discharge pipe, and the discharge head and the reflux head are connected to the one-way discharge valve and the one-way reflux valve. The one-way discharge valve plays a one-way liquid discharge role on the discharge head, ensuring that the liquid smoothly enters the cooling shell and the cooling pipe, and the one-way reflux valve ensures that the liquid discharged from the cooling shell and the cooling pipe smoothly flows back into the discharge pipe.

[0010] Furthermore, a thermal pad is provided between the cooling shell and the magnetic pump head, and the thermal pad can fill the gap between the cooling shell and the magnetic pump head to improve the heat conduction efficiency and avoid local high temperature of the magnetic pump head.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) Liquid is provided to the cooling shell and cooling pipe through the discharge head. When the heat of the magnetic pump head is transferred to the cooling shell, and the heat of the motor is transferred to the cooling pipe, the heat of the magnetic pump head and the motor is taken away by the flowing liquid, which can continuously dissipate heat for the magnetic pump, ensuring that the magnetic pump is not prone to overheating during long-term operation.

[0013] (2) The medium transported by the magnetic pump dissipates heat for the magnetic pump, and no additional heat dissipation equipment is required. The structure is streamlined, and the one-way discharge valve and the one-way return valve are used to ensure smooth circulation of the liquid, thereby achieving circulating heat dissipation of the magnetic pump.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] See also Figure 1-4 The utility model provides a technical solution: a filling magnetic pump with a cooling mechanism, comprising a base 1, a motor 2 is installed on the base 1, a magnetic pump head 4 is installed on the motor 2, the magnetic pump head 4 has a discharge pipe 5, the discharge pipe 5 is connected with a discharge head 6 and a return head 9, the discharge head 6 can divert a part of the medium, and the diverted medium flows back through the return head 9;

[0022] A cooling shell 11, which is sleeved on the outside of the magnetic pump head 4. The upper and lower surfaces of the cooling shell 11 are respectively connected with a liquid discharge head 12 and a liquid inlet head 13. The liquid inlet head 13 is located below the cooling shell 11 to ensure that the liquid fills the cooling shell 11, so that the heat generated by the magnetic pump head 4 is smoothly transferred to the liquid;

[0023] The cooling pipe 14 is coiled on the surface of the motor 2. The cooling pipe 14 is bent in a serpentine shape and bent twice to form a ring shape. It can be smoothly installed with the motor 2. The two ends of the cooling pipe 14 are respectively connected to the discharge head 6 and the return head 9. The surface of the cooling pipe 14 is sleeved with a heat-conducting shell 3, and the heat-conducting shell 3 is located outside the motor 2. The heat-conducting shell 3 can protect the cooling pipe 14 from damage.

[0024] In this embodiment, if Figure 1 As shown, a one-way discharge valve 7 and a one-way reflux valve 8 are installed on the discharge pipe 5, and the discharge head 6 and the reflux head 9 are connected to the one-way discharge valve 7 and the one-way reflux valve 8. The one-way discharge valve 7 ensures that the liquid in the discharge pipe 5 can only enter the one-way discharge valve 7, and the one-way reflux valve 8 ensures that the liquid in the discharge pipe 5 will not enter the one-way reflux valve 8, thereby ensuring that the liquid can flow smoothly in the cooling shell 11 and the cooling pipe 14.

[0025] In this embodiment, if Figure 2 and Figure 4 As shown, a plurality of partition bars 10 are provided on the surface of the motor 2, and the cooling pipe 14 is placed between two adjacent partition bars 10. The partition bars 10 conduct heat to the portion of the motor 2 surface that is not covered by the cooling pipe 14, so that the motor 2 can be evenly cooled.

[0026] In this embodiment, if Figure 3As shown, a thermal pad 15 is provided between the cooling shell 11 and the magnetic pump head 4. The thermal pad 15 is soft and deformable. The thermal pad 15 is clamped by the cooling shell 11 and the magnetic pump head 4 so that the thermal pad 15 fills the gap between the cooling shell 11 and the magnetic pump head 4, thereby ensuring higher heat transmission efficiency.

[0027] In this embodiment, if Figure 4 As shown, a plurality of heat-conducting strips 16 are provided on the surface of the heat-conducting shell 3. The heat-conducting strips 16 can effectively increase the contact area between the heat-conducting shell 3 and the air, thereby improving the passive heat dissipation efficiency.

[0028] In this embodiment, if Figure 1 As shown, the one-way discharge valve 7 is tilted upward so that one end of the one-way discharge valve 7 extends into the discharge pipe 5, which is beneficial for the liquid to enter the one-way discharge valve 7. The one-way return valve 8 is tilted downward so that the end of the one-way return valve 8 is flush with the inner wall of the discharge pipe 5, which is beneficial for the liquid to flow smoothly to the discharge pipe 5 through the one-way return valve 8.

[0029] Specifically, during use, when the motor 2 drives the magnetic pump head 4 to work, the magnetic pump head 4 extracts liquid and discharges it into the discharge pipe 5. After the liquid is pressurized by the magnetic pump head 4, when the liquid flows in the discharge pipe 5, part of the liquid enters the one-way discharge valve 7 and is divided into two parts under the action of the discharge head 6, and flows to the liquid inlet head 13 and the cooling pipe 14 respectively. The liquid flows upward from the lower part of the cooling pipe 14 and is discharged into the reflux head 9 through the discharge head 12. When the heat generated by the operation of the magnetic pump head 4 is transferred to the cooling shell 11, the liquid flow takes away the heat to cool the magnetic pump head 4. The heat generated by the operation of the motor 2 is transferred to the dividing strip 10 and the cooling pipe 14. The liquid flows in the cooling pipe 14 to cool the motor 2 to ensure that the motor 2 does not overheat.
