Description

Technical Field

[0001] The present invention relates to the technical field of cooling equipment, and particularly to a power cord cooling device. Background Art

[0002] With the development of the economy and the progress of technology, people use more and more electronic devices, and at the same time, the usage of power cords of electronic devices also increases accordingly. A power cord is a wire for transmitting current. After the power cord is extruded or drawn, the temperature of the copper wire will be relatively high. If it is not cooled in time, it is not only easy to damage the wire take-up device, but also easy to cause phenomena such as cracks and deformation of the copper wire. Therefore, a cooling device needs to be provided to cool its surface.

[0003] The traditional cooling method is air cooling, but the air cooler is likely to cause excessive melting of the outer surface of the power cord, seriously affecting the quality and appearance of the power cord. For the existing power cord water cooling device, the extruded power cord is heat-absorbed through a water pipe, but the heat absorption effect is poor and it takes a relatively long distance of heat absorption to reduce the temperature of the power cord. Moreover, the power cord water cooling device needs to continuously pump cold water through a water pump, and the cold water cannot be recycled after heat absorption, seriously wasting water resources.

[0004] Therefore, a power cord cooling device is needed to solve the above problems. Summary of the Invention

Detailed implementation manners

[0026] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to relevant attached drawings. Preferred embodiments of this application are shown in the attached drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of this application more thorough and comprehensive.

[0027] The technical solutions of the present invention will be further described below in conjunction with the attached drawings and specific embodiments.

[0028] See Figure 1 As shown, a power cord cooling device includes a cooling water tank 1. One end of the cooling water tank 1 is installed with a wire inlet wheel 2, and the other end of the cooling water tank 1 is installed with a wire outlet wheel 3. In the embodiment of the present invention, both the wire inlet wheel 2 and the wire outlet wheel 3 are a pair of symmetrically arranged roller wheels. The roller wheel of the wire inlet wheel 2 is rotatably arranged at one end of the cooling water tank 1. See Figure 2 As shown, one of the wheel shafts of the pair of roller wheels of the wire outlet wheel 3 is connected to the drive shaft 17, and the drive shaft 17 is connected to the motor shaft of the servo motor 18. Driven by the servo motor 18, the roller wheels of the wire outlet wheel 3 are driven to rotate through the drive shaft 17; a wire feeding channel 5 is provided in the cooling water tank 1 between the wire inlet wheel 2 and the wire outlet wheel 3. When cooling the power cord, the power cord enters the wire feeding channel 5 between the roller wheels of the wire inlet wheel 2 and is output between the roller wheels of the wire outlet wheel 3. Driven by the servo motor 18, it is convenient for the power cord to be inserted and pulled out.

[0029] See Figure 1 As shown, a sealing plug 4 is provided at the wire outlet end of the wire feeding channel 5. A wire passing hole for the power cord to pass through is provided in the middle of the sealing plug 4. The sealing plug 4 is used to increase the sealing performance of the wire feeding channel 5 at the wire outlet end and prevent the coolant or cooling gas in the wire feeding channel 5 from overflowing from the wire outlet end when the power cord passes through;

[0030] In an embodiment of the present invention, see Figure 5As shown, the interior of the cooling water tank 1 is defined as a cooling chamber 12, and a cooling pipe 10 is installed in the cooling chamber 12. In the embodiment of the present invention, the cooling pipe 10 is spirally wound around the wire feeding channel 5, and the wire feeding channel 5 is communicated with the cooling chamber 12. A low-temperature cooling medium is input into the cooling pipe 10, and the low-temperature cooling medium in the cooling pipe 10 absorbs the heat in the cooling chamber 12 and cools it down. The low-temperature cooling chamber 12 directly cools the power cord passing through the wire feeding channel 5, thereby realizing the cooling of the power cord.

[0031] As a preferred embodiment of the present invention, refer to Figure 4 As shown, the wire feeding channel 5 is arranged in the heat dissipation body 6, and the heat dissipation body 6 is made of a copper or aluminum block with a high thermal conductivity coefficient. Under the isolation of the heat dissipation body 6, the wire feeding channel 5 and the cooling chamber 12 are not communicated with each other. Preferably, the cooling pipe 10 is spirally wound around the heat dissipation body 6 or spirally embedded in the heat dissipation body 6, so as to facilitate the cooling of the heat dissipation body 6 by the low-temperature cooling medium and realize the cooling of the power cord passing through the wire feeding channel 5 in the heat dissipation body 6.

[0032] Refer to Figure 1 As shown, in order to further improve the cooling effect and reliability of the power cord in the wire feeding channel 5, the cooling pipe 10 is spirally embedded in the heat dissipation body 6, and a metal cylinder 7 is sleeved outside the heat dissipation body 6. Heat conduction blocks 8 are arranged on the outer side wall of the metal cylinder 7, and the heat conduction blocks 8 are distributed at intervals. A plurality of heat dissipation holes 9 are arranged on the side wall of the metal cylinder 7 between the heat conduction blocks 8. The interior of the cooling water tank 1 outside the metal cylinder 7 is defined as a water drainage groove 11;

[0033] The upper part of the cooling water tank 1 is connected to a cooling pipe joint 13, and the lower part of the cooling water tank 1 is connected to a return pipe joint 14. The cooling pipe joint 13 and the return pipe joint 14 are connected to a refrigeration box 15 through a water pipe, and a circulation pump 16 is installed on the water pipe between the cooling pipe joint 13 and the refrigeration box 15.

[0034] When cooling down the power cord, the power cord conducts heat to the heat dissipation body 6, the heat dissipation body 6 conducts the heat to the metal cylinder 7, and then conducts it to the heat conduction blocks 8; when the circulation pump 16 is started to work, the circulation pump 1 picks up the cooling water in the refrigeration box 15 and injects it into the water drainage groove 11 of the cooling water tank 1 through the cooling pipe joint 13. A part of the cooling water enters the metal cylinder 7 along the heat dissipation holes 9 and contacts the heat dissipation body 6 to directly cool it down, and absorbs the heat conducted to the metal cylinder 7 and the heat conduction blocks 8 together, and the cooled water flows back to the refrigeration box 15 along the return pipe joint 14 for cooling; at the same time, the low-temperature medium flowing in the cooling pipe 10 also directly cools the heat dissipation body 6, so as to facilitate the direct absorption of the heat of the power cord in the wire feeding channel 5 and quickly cool down the power cord in the wire feeding channel 5.

[0035] As a preferred embodiment of the present invention, in order to increase the cooling path of the power cord in the cooling water tank 1, preferably, the wire feeding channel 5 can also be distributed in an S shape. By increasing the path of the wire feeding channel 5, the cooling time of the power cord is increased, and the cooling effect is improved.

[0036] The technical principle of the present invention has been described above in conjunction with specific embodiments, which are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. Those skilled in the art can readily conceive of other specific embodiments of the present invention without creative efforts, and these embodiments will fall within the protection scope of the present invention.
