Description

Technical Field

[0001] The utility model relates to a motor cooling structure, and in particular to a new cooling circulation system for a linear motor. Background Art

[0002] The cooling system used in the existing linear motor is as shown in Figure 1 or Figure 2. The cooling pipe B is wound around the coil winding A. The coolant flows in from the pipe head inlet. The coolant passes through the pipe to take away the heat of the coil winding, and finally flows out from the pipe head outlet to achieve the purpose of heat dissipation.

[0003] The disadvantage of the above structure is that the cooling pipe is installed inside the linear motor, and a bottom plate C is installed at the bottom of the linear motor; since the silicon steel sheet is directly fixed on the bottom plate, the heat of the coil winding will pass through the silicon steel sheet, directly transfer to the bottom plate, and then transfer to the air, so that the heat is dissipated. Such a heat dissipation method is very slow and affects the heat dissipation efficiency of the linear motor. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above problems of the existing technology, and provide a new cooling circulation system for a linear motor with a simple structure and good heat dissipation effect.

[0006] A new cooling circulation system for a linear motor includes a bottom plate, a coil winding and a cooling component which cooperate with each other; wherein, the coil winding is fixed on the bottom plate, and the cooling component includes a cooling pipe and a bottom plate cooling pipe which are communicated with each other. The cooling pipe bypasses the silicon steel sheet of the coil winding and is communicated with the bottom plate cooling pipe. The coolant enters the cooling pipe from one end of the cooling pipe, enters the bottom plate cooling pipe through the cooling pipe, and then flows out from the outlet of the bottom plate cooling pipe.

[0007] Further, the cooling pipe includes a liquid inlet end, a pipe, and a liquid outlet end which cooperate with each other; a liquid inlet is opened at the liquid inlet end, the liquid inlet is communicated with one end of the pipe, the pipe bypasses the silicon steel sheet of the coil winding and is communicated with the liquid outlet end, and a connection port is opened at the bottom of the liquid outlet end and is communicated with the bottom plate cooling pipe. A sealing ring is provided at the connection port for sealing.

[0008] Further, the bottom plate cooling pipe includes an inlet, a bottom pipe, and an outlet which cooperate with each other; the inlet is arranged on the upper surface of the bottom plate and is butted against the connection port of the cooling pipe, the bottom pipe is arranged inside the bottom plate, the outlet is arranged on the side surface of the bottom plate, one end of the bottom pipe is communicated with the inlet, and the other end is communicated with the outlet.

[0009] Further, the bottom pipe is of an H-shaped structure, with two side pipes arranged on both sides of the bottom plate, and a middle pipe connected between the two side pipes.

[0010] Further, the bottom pipe is of a wavy structure.

[0011] After adopting the above solution, compared with the prior art, since the cooling circuit is added to the bottom plate of the present utility model, it is communicated with the cooling pipe, and the sealing ring is used to ensure the sealing of the connection, the original outlet of the cooling pipe is blocked, and holes communicating with the bottom plate are added to the pipe head, so that the coolant flows into the bottom plate circuit. The heat dissipation of the bottom plate is accelerated, thereby improving the overall heat dissipation efficiency of the linear motor. Brief Description of the Drawings

[0016] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0017] As Figure 3-4 shown, a new cooling circulation system for a linear motor includes a bottom plate 1, a coil winding 2 and a cooling component 3 that cooperate with each other; wherein, the coil winding 2 is fixed on the bottom plate 1, and the cooling component 3 includes a cooling pipe 31 and a bottom plate cooling pipe 32 that are communicated with each other. The cooling pipe 31 bypasses the silicon steel sheet of the coil winding 2 and is communicated with the bottom plate cooling pipe. The coolant enters the cooling pipe from one end of the cooling pipe and enters the bottom plate cooling pipe 32 through the cooling pipe and then flows out from the outlet of the bottom plate cooling pipe.

[0018] In a specific embodiment, the cooling pipe 31 includes a liquid inlet end 311, a pipe 312 and a liquid outlet end 313 that cooperate with each other; a liquid inlet 314 is opened at the liquid inlet end 311, the liquid inlet 314 is communicated with one end of the pipe 312, the pipe 312 bypasses the silicon steel sheet of the coil winding 2 and is communicated with the liquid outlet end 313, and a connection port 315 is opened at the bottom of the liquid outlet end 313 and is communicated with the bottom plate cooling pipe 32, and a sealing ring 316 is provided at the connection port 315 for sealing.

[0019] The bottom plate cooling pipe 32 includes an inlet 321, a bottom pipe 322 and an outlet 323 that cooperate with each other; the inlet 321 is arranged on the upper surface of the bottom plate 1 and is butted against the connection port 315 of the cooling pipe 31, the bottom pipe 322 is arranged inside the bottom plate 1, the outlet 323 is arranged on the side surface of the bottom plate 1, one end of the bottom pipe 322 is communicated with the inlet 321, and the other end is communicated with the outlet 323.

[0020] Furthermore, the bottom pipe 322 is of H-shaped structure, with the two side pipes arranged on both sides of the bottom plate and the middle pipe connected between the two side pipes; or it is of wavy structure.

[0021] In the present utility model, since a cooling circuit is added to the bottom plate, which is communicated with the cooling pipe, and a sealing ring is used to ensure the sealing performance at the communication part, the original outlet of the cooling pipe is blocked, and holes communicating with the bottom plate are added to the pipe head, so that the coolant flows into the bottom plate circuit. This accelerates the heat dissipation of the bottom plate, thereby improving the overall heat dissipation efficiency of the linear motor.
