Description

Technical Field

[0001] The utility model relates to the technical field of laser power supplies, in particular to a cooling structure and a power supply device thereof. Background Art

[0002] During the operation of the power supply system, the power module and laser will generate a lot of heat. If the heat cannot be dissipated in a timely and effective manner, it will lead to equipment performance degradation, shortened lifespan, and even cause serious safety accidents.

[0003] Traditional heat dissipation methods typically rely on independent cooling fans. These fans rotate to generate airflow, removing heat generated by the power module and laser. Heat is then dissipated to the surrounding environment through structures such as heat sinks or heat pipes. However, this heat dissipation method has several problems. First, the cooling fan consumes additional power, which increases the energy consumption of the entire power supply system. Second, the rotation of the fan generates noise, which affects the user experience. Furthermore, the fan has a limited lifespan and requires regular replacement, increasing maintenance costs. More importantly, if the fan fails, it will directly affect the heat dissipation of the power module and laser, potentially causing overheating and damage to the equipment. Utility Model Content

Specifically, the power module 2 is electrically connected to the laser 1 to power the laser 1, or the laser 1 is connected to the power grid or a driver 21 to power the laser 1. This embodiment illustrates a specific implementation of power supply via a power grid busbar, creating two power supply modes: the power module 2 and the power grid busbar alternately power the laser 1. During the power supply process, various components need to be cooled. The cooling structure 100 also includes a water cooling pack 3, which is provided with a cold storage inlet 31, a cold storage outlet 32, and a water cooling chamber 33. The water cooling chamber 33 is internally disposed within the water cooling pack 3. The cold storage inlet 31 communicates with one end of the water cooling chamber 33, and the cold storage outlet 32 ​​communicates with the other end of the water cooling chamber 33. A cooling medium is introduced from the cold storage inlet 31, flows through the water cooling chamber 33, and is discharged from the cold storage outlet 32, thereby dissipating heat and cooling the water cooling pack 3. The water cooling pack 3 is connected to a first cooling circuit 4 and a second cooling circuit 5 . The first cooling circuit 4 is used to dissipate heat for the laser 1 , and the second cooling circuit 5 is used to dissipate heat for the power module 2 .

[0025] like Figure 1 As shown, specifically, the first cooling circuit 4 includes a first radiator 41, a first heat pipe 42, and a first pump 43.

The first radiator 41 is fixedly connected to the side of the water-cooling pack 3. The heat from the first radiator 41 is directly transferred to the water-cooling pack 3, and the heat is removed by the flow of the cooling medium within the water-cooling pack 3. The first radiator 41 is in surface contact with the water-cooling pack 3, increasing the contact area between the first radiator 41 and the water-cooling pack 3, further improving the heat dissipation effect.

[0026] The second cooling circuit 5 includes a second radiator 51, a second heat dissipation pipe 52, and a second pump body 53. The second heat dissipation pipe 52 passes through the second heat dissipation pipe 52 and the second pump body 53 to form a circulation loop.

Preferably, the second heat dissipation pipe 52 is wound around the outer surface of the power module 2 in multiple bends. The second pump body 53 accelerates the flow of the cooling medium in the second heat dissipation pipe 52 to enhance the heat dissipation effect. The second radiator 51 is fixedly connected to the side of the water-cooling pack 3. The heat from the second radiator 51 is directly transferred to the water-cooling pack 3, and the heat is removed by the flow of the cooling medium in the water-cooling pack 3. The second radiator 51 is in surface contact with the water-cooling pack 3 to increase the contact area between the second radiator 51 and the water-cooling pack 3, further improving the heat dissipation effect.

[0027] The cooling structure 100 includes a third cooling circuit 6 for dissipating heat from the driver 21. The third cooling circuit 6 includes a third radiator 61, a third heat pipe 62, and a third pump body 63. In this embodiment, the third heat pipe 62 is attached to the outer peripheral side of the driver 21. In other embodiments, the third heat pipe 62 can dissipate heat for other electronic components, such as control circuits, capacitors, etc. The third heat pipe 62 passes through the third radiator 61 and the third pump body 63 to form a circulation loop. Preferably, the third radiator 61 is indirectly in contact with the water-cooling pack 3 through the second radiator 51, that is, the third radiator 61 is in surface contact with the second radiator 51, and the second radiator 51 is in surface contact with the water-cooling pack 3 to optimize the overall spatial layout. More preferably, the third radiator 61 is in direct surface contact with the water-cooling pack 3 to enhance the heat dissipation effect of the third radiator 61.

[0028] In this embodiment, the medium in the first heat dissipation tube 42 is ethylene glycol or water, the medium in the second heat dissipation tube 52 is pure polyethylene glycol, and the medium in the third heat dissipation tube 62 is ethylene glycol or water.

[0029] like Figure 2 As shown, the present application also provides a power supply device for continuously supplying power to the laser 1. A power supply device includes a PCS module 9 with a built-in AC-DC converter, a first switch 71, a second switch 72, and a third switch 73.

It is worth noting that the PCS module 9 with a built-in AC-DC converter has a bidirectional power supply operation, which can be used for charging and can also be inverted into AC power to supply power to the cooling structure 100, that is, to supply power to the first pump body 43, the second pump body 53, and the third pump body 63.

[0030] The PCS module 9 with a built-in AC-DC converter is connected in series and connected to the AC bus through the first switch 71. That is, the PCS module 9 with a built-in AC-DC converter is connected in series and connected to the power grid through the first switch 71.

[0032] The above scheme provides two power supply modes for the laser 1:

[0033] Method 1: When the power grid fails or is far away from the power grid, or there is no driving component 21 to generate electricity, the ATS module 8 controls the first switch 71 and the third switch 73 to be disconnected, the second switch 72 is normally closed, and the power supply module 2 directly powers the laser 1. At the same time, the cooling structure 100 is powered by the PCS module 9 with a built-in AC-DC converter.

[0034] Method 2: When the battery is exhausted, the ATS module 8 controls the first switch 71, the second switch 72 and the third switch 73 to be normally closed, and the power grid supplies power to the power module 2, the laser 1 and the cooling structure 100 through the PCS module 9 with a built-in AC-DC converter.
