Abstract
Description
Technical Field
[0001] The present application relates to the field of wire technology, and in particular to a high heat dissipation magnetic wire copper tube. Background Art
[0002] Copper wire is a commonly used industrial product in modern industry. Because copper wire has a high cost-effectiveness in conductivity and strong plasticity, it is widely used in electricity and some fields involving magnetism.
[0003] Due to the electromagnetic induction phenomenon and the high conductivity of copper wire, copper wire is often used as a magnetic field generator in electromagnetic induction and used in motors or other equipment that requires a magnetic field. In high-voltage alternating current, the copper coil will generate a lot of heat. Therefore, when used for a long time or in high-power equipment, it is necessary to configure the copper coil with a corresponding heat dissipation device, or wait for a long time for natural cooling after a single use.
[0004] However, the natural cooling speed is slow and the heat dissipation device is not suitable for some compact equipment, resulting in low heat dissipation efficiency and inconvenient application, so it needs to be improved. Utility Model Content
[0005] In order to improve the problem of low heat dissipation efficiency of wires, the present application provides a high heat dissipation magnetic wire copper tube.
[0006] The high heat dissipation magnetic wire copper tube provided in this application adopts the following technical solution:
[0007] A high heat dissipation magnetic wire copper tube comprises a wire body, wherein the end of the wire body is provided with a heat-conducting cavity along the length direction for a heat-conducting medium to pass through.
[0008] By adopting the above technical solution, during the operation of the conductor body, a cooling medium such as a coolant is introduced into the heat-conducting cavity, and the flowing cooling medium takes away the heat generated during the operation of the conductor body, thereby accelerating the heat dissipation.
[0009] Preferably, a plurality of groups of grooves are formed on the inner side wall of the heat-conducting cavity, all of the grooves are sequentially distributed along the circumference of the heat-conducting cavity, and all of the grooves are arranged along the length direction of the heat-conducting cavity.
[0010] By adopting the above technical solution, the heat conduction groove has the advantage of low thermal resistance. Since there is no obstruction of copper powder filler, the permeability of cooling medium such as coolant inside the heat conduction groove is better, thereby improving the heat dissipation efficiency of the wire body; and the longer the length of the wire body, the more obvious the design advantage of opening the heat conduction groove.
[0011] Preferably, the cross-section of the wire body along its radial direction is rectangular.
[0012] By adopting the above technical solution, the current carrying capacity of the rectangular cross-section conductor is greater than that of the circular cross-section conductor, so the rectangular conductor body has better heat dissipation performance.
[0013] Preferably, a chamfer is provided on the peripheral wall of the wire body.
[0014] By adopting the above technical solution, chamfering reduces burrs on the outer peripheral wall of the wire body, reduces the occurrence of the wire body scratching the user during the trial, and ensures the practical safety and convenience of the wire body.
[0015] Preferably, a plurality of heat dissipation cavities for the heat-conducting medium to pass through are provided inside the wire body along the length direction, and all the heat dissipation cavities are distributed around the heat-conducting cavity at intervals.
[0016] By adopting the above technical solution, during the operation of the conductor body, a cooling medium such as a coolant is introduced into the heat dissipation cavity, and the flowing cooling medium takes away the heat generated during the operation of the conductor body, thereby accelerating the heat dissipation; and the heat dissipation cavity further increases the heat dissipation path of the conductor body, thereby improving the heat dissipation efficiency of the conductor body.
[0017] Preferably, each of the heat dissipation cavities is communicated with the heat conduction cavity.
[0018] By adopting the above technical solution, the heat dissipation cavity and the heat-conducting cavity that are interconnected make it possible to introduce a cooling medium such as a coolant into the heat-conducting cavity or one group of the heat dissipation cavities, so that the cooling medium can be filled into all the heat dissipation cavities and the heat-conducting cavities to achieve cooling and heat dissipation treatment of the wire body, thereby improving the convenience of heat dissipation treatment of the wire body; in addition, the heat-conducting cavity and the heat dissipation cavity that are interconnected further increase the contact area between the inside of the wire body and the cooling medium, so as to better transfer heat, thereby achieving a better improvement in the heat dissipation efficiency of the wire body.
[0019] Preferably, the inner side wall of each heat dissipation cavity is provided with a plurality of groups of heat conduction grooves along the length direction of the wire body.
[0020] By adopting the above technical solution, the heat conduction groove further reduces the thermal resistance inside the wire body, further increases the contact area between the cooling medium and the wire body, and increases the permeability of cooling media such as coolant inside the heat conduction groove, thereby improving the heat dissipation efficiency of the wire body.
[0021] Preferably, a heat conducting layer is disposed outside the wire body.
[0022] By adopting the above technical solution, the heat-conducting layer has good thermal conductivity and corrosion resistance. On the one hand, it can protect the wire body and extend the service life of the wire body; on the other hand,
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. A heat-conducting cavity is provided inside the conductor body, and during the operation of the conductor body, a cooling medium such as a coolant is introduced into the heat-conducting cavity. The flowing cooling medium takes away the heat generated during the operation of the conductor body, thereby accelerating the heat dissipation.
[0025] 2. By providing a heat dissipation cavity connected to the heat conduction cavity, the contact area between the inside of the wire body and the cooling medium is further increased, so as to better transfer heat and achieve better improvement of the heat dissipation efficiency of the wire body.

In this embodiment, the cross section of the wire body 1 along its radial direction is rectangular, and the outer peripheral wall of the rectangular wire body 1 is provided with a chamfer to facilitate the use of the wire body 1.
[0035] The implementation principle of a high heat dissipation magnetic wire copper tube in Example 1 of the present application is:
[0036] During use of the conductor body 1 , coolant is introduced into the heat-conducting cavity 11 , and the flowing coolant transfers the heat generated by the conductor body 1 , which has the effect of quickly dissipating the heat of the conductor body 1 , thereby improving the heat dissipation efficiency of the conductor body 1 .
[0037] Embodiment 2:
[0038] The difference between Example 2 and Example 1 is: Figure 2 , a plurality of heat dissipation cavities 12 are provided inside the wire body 1 along the length direction of the wire body 1 for the heat conducting medium to flow through. In this embodiment, all the heat dissipation cavities 12 are distributed along the circumferential intervals of the heat conducting cavity 11, and the interior of each heat dissipation cavity 12 is connected to the interior of the heat conducting cavity 11.
[0039] Reference Figure 2 Each group of heat dissipation cavities 12 is provided with heat conduction grooves 121 , all the heat conduction grooves 121 are distributed at intervals along the circumference of the corresponding heat dissipation cavity 12 , and each group of heat conduction grooves 121 is extended along the length direction of the corresponding heat dissipation cavity 12 .
