Description

Technical Field

[0001] The utility model relates to the technical field of electromagnets, in particular to an electromagnet water cooling device. Background Art

[0002] An electromagnet is a device that generates electromagnetism when electricity is applied. A conductive winding matching its power is wound around the outside of the iron core. This coil with current flowing through it has magnetic properties like a magnet. The electromagnet needs to be cooled after use to avoid overheating and damage to the coil, which would affect the service life of the lifting electromagnet.

[0003] For example, the utility model with application number CN201921626754.2 discloses a water cooling device for a lifting electromagnet, which is provided with a plurality of concentric annular pipes. The coolant is collected into the straight pipe during the flow process, so that the heat dissipation of the lifting electromagnet is more uniform, and the coolant is dissipated more thoroughly through the fan and the heat dissipation groove. At the same time, a continuous curved heat dissipation water channel is formed inside the heat exchanger water tank to promote the flow of the coolant and accelerate the heat dissipation of the coolant, thereby making the heat dissipation of the lifting electromagnet more thorough.

[0004] The water cooling device of the lifting electromagnet similar to the above application still has the following shortcomings:

[0005] The copper tubes embedded in the surface of the heat exchanger of the electromagnet water cooling device cannot be made flat, and there are gaps between the coils and the heat exchanger, forming many heat traps, resulting in low heat exchange efficiency, large heat loss, and low thermal conductivity efficiency.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and an electromagnet water cooling device is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide an electromagnet water cooling device to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electromagnet water cooling device, comprising a heat exchanger, a winding drum and a reinforcement component, a water channel is opened inside the heat exchanger, and through openings are opened at the left and right ends of the front side of the heat exchanger, a water nozzle is connected through the front end of the through opening, the winding drum is fixedly connected to the inner side of the middle part of the heat exchanger, and the upper ends of the upper and lower sides of the winding drum are fixedly connected to cover plates, the outer side of the winding drum is connected to a through-wire winding, and the reinforcement component for reinforcement and protection is arranged at the outer end of the winding drum.

[0009] Furthermore, two heat exchangers are symmetrically arranged about the winding drum, and the winding drum is hollow.

[0010] Furthermore, the water channel is communicated with the water nozzle, and the water nozzle is snap-connected with the heat exchanger.

[0011] Furthermore, the structural dimensions of the outer opening of the cover plate are consistent with the structural dimensions of the water channel opening, and the water channel is in the shape of an open ring.

[0012] Furthermore, the reinforcement assembly includes an outer cylinder shell and a reinforcement block, and the inner part of the outer cylinder shell is connected with the reinforcement block.

[0013] Furthermore, the reinforcement blocks are equidistantly distributed around the inner circumference of the outer cylindrical shell, and the reinforcement blocks are arc-shaped.

[0014] Furthermore, the reinforcement component also includes a thermally conductive insulating silicone grease layer, and the inner wall of the outer cylinder shell and the outer wall of the winding cylinder are bonded with the thermally conductive insulating silicone grease layer.

[0015] The utility model provides an electromagnet water cooling device, which has the following beneficial effects:

[0016] The heat exchange efficiency between water and heat exchange medium is improved by opening water channels. At the same time, since the surface is coated with insulating thermal conductive coating, the volume of air medium between the coil and the heat exchange medium is reduced, heat traps are avoided, and the insulation between the coil and the heat exchanger is improved.

[0017] 1. The utility model is provided with a water channel. A water channel is opened inside the heat exchanger to replace the traditional copper tube laying and circulating coolant, which greatly avoids the unevenness of the copper tube inlay and the gaps, thereby causing heat sinks. Direct contact cooling is achieved through the opening of the water channel, which increases the contact surface between the coil and the cooling device, reduces heat sinks, and improves the cooling efficiency of the electromagnet.

[0018] 2. The utility model is provided with a thermally conductive insulating silicone grease layer. A cavity is formed by clamping the water channel opening with a cover plate at the connection between the winding drum and the heat exchanger. Correspondingly, the connection between the two is sealed and reinforced by a thermally conductive insulating silicone grease layer to improve the connection strength between the two, avoid leakage, and enhance the thermal conductive cooling effect.

[0019] 3. The utility model is provided with a reinforcement block, and a plurality of arc-shaped reinforcement blocks are installed equidistantly inside the outer cylinder shell. The strength of the through-wire winding at the outer end of the entire winding cylinder is reinforced by the arrangement of the outer cylinder shell and the reinforcement blocks, thereby improving its service life.

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] like Figure 1 and Figure 3 As shown, an electromagnet water cooling device includes a heat exchanger 1, a winding tube 5 and a reinforcement component 8. A water channel 2 is opened inside the heat exchanger 1, and a through hole 3 is opened at the left and right ends of the front side of the heat exchanger 1. A water nozzle 4 is connected through the front end of the through hole 3. The water channel 2 is connected to the water nozzle 4, and the water nozzle 4 is snap-connected to the heat exchanger 1. A water channel 2 is opened inside the heat exchanger 1 to replace the traditional copper tube laying and circulating coolant, which greatly avoids the uneven inlay of the copper tube and leaves pores, thereby causing heat sinks. Direct contact cooling is achieved through the opening of the water channel 2, which increases the contact area between the coil and the cooling device, reduces heat sinks, and improves the cooling efficiency of the electromagnet.

[0027] like Figure 1 and Figure 2 As shown, the winding drum 5 is fixedly connected to the inner side of the middle of the heat exchanger 1, and the upper ends of the upper and lower sides of the winding drum 5 are fixedly connected with a cover plate 6. The outer opening structure size of the cover plate 6 is consistent with the opening structure size of the water channel 2, and the water channel 2 is an open ring. At the connection between the winding drum 5 and the heat exchanger 1, the cover plate 6 is used to clamp the opening of the water channel 2 to form a sealed cavity for the water channel 2 to flow and weld and reinforce it. Correspondingly, a layer of thermal conductive insulating silicone grease layer 803 is padded at the connection between the two to seal and reinforce them, so as to improve the connection strength between the two and the heat exchange and cooling effect. A through-wire winding 7 is connected to the outside of the winding drum 5, and a reinforcement component 8 for reinforcement and protection is arranged at the outer end of the winding drum 5.

[0028] like Figure 1 and Figure 4 As shown, the reinforcement assembly 8 includes an outer cylinder shell 801 and a reinforcement block 802, and the outer cylinder shell 801 is connected to the reinforcement block 802, and the reinforcement blocks 802 are evenly distributed about the inner circumference of the outer cylinder shell 801, and the reinforcement blocks 802 are arc-shaped, and multiple arc-shaped reinforcement blocks 802 are evenly installed inside the outer cylinder shell 801. The strength of the through-wire winding 7 at the outer end of the entire winding drum 5 is reinforced by the arrangement of the outer cylinder shell 801 and the reinforcement blocks 802, thereby improving its service life. The reinforcement assembly 8 also includes a thermally conductive insulating silicone grease layer 803, and the inner wall of the outer cylinder shell 801 and the outer wall of the winding drum 5 are bonded with the thermally conductive insulating silicone grease layer 803.

[0029] In summary, if Figures 1 to 4 As shown, when the electromagnet water cooling device is used, the device first uses aluminum alloy as raw material, processes a water channel 2 for water supply and circulation on the surface of the heat exchanger 1, and then seals the water channel 2 by welding and reinforcing the cover plate 6 with the structural size matching the upper end of the winding drum 5, and finally grinds the surface of the heat exchanger 1. A water nozzle 4 connected to the external water pipe is installed at the position where the water channel 2 is located on the side of the heat exchanger 1, and a layer of thermal conductive insulating silicone grease layer 803 is applied on the surface of the heat exchanger 1 and the surface of the winding drum 5, and the thermal conductive insulating silicone grease layer 803 is correspondingly connected to the end face of the coil, and then when water is injected into the water nozzle 4, the cooling liquid circulates through the annular water channel 2 for efficient heat dissipation. Through this direct contact cooling, the contact surface between the coil and the cooling device is increased, the heat sink is reduced, and the cooling efficiency of the electromagnet is improved. A plurality of arc-shaped reinforcement blocks 802 are equidistantly installed inside the outer cylinder shell 801, and the strength of the through-wire winding 7 at the outer end of the entire winding drum 5 is reinforced by the arrangement of the outer cylinder shell 801 and the reinforcement blocks 802, thereby improving its service life.
