[0029] Combine the following Figure 1-Figure 6 The utility model is described in detail.

[0030] Example

[0031] A water-cooled plate for a high-power heating tube comprises a substrate 1, a first copper plate 3 for placing a heating tube 2 is mounted on the substrate 1, a first cavity 302 is arranged in the first copper plate 3, a baffle 305 is arranged in the first cavity 302, a water inlet 304 and a water outlet 307 are arranged on both sides of the baffle 305 respectively in the first cavity 302, and a plurality of first fins 303 are arranged in the first cavity 302.

[0032] like Figure 4 As shown, cooling water enters the first cavity 302 from the water inlet 304, and the cooling water flows around the baffle 305 to the water outlet 307; the heat generated by the heating tube 2 is conducted to the first cavity 302 through the first copper plate 3 and exchanges heat with the flowing cooling water, thereby cooling the heating tube 2, and the first fin 303 can increase the contact area between the first copper plate 3 and the cooling water, thereby improving the heat exchange efficiency.

[0033] A plurality of protrusions 306 are disposed in the first cavity 302 . The protrusions 306 can cause the flowing cooling water to generate turbulence, thereby increasing the heat exchange effect of the cooling water.

[0034] In order to place multiple heating tubes 2, a second copper plate 4 for placing the heating tubes 2 is also installed on the substrate 1, and the number of the second copper plates 4 can be increased according to demand; Figure 5 As shown, two second cavities 403 are provided in the second copper plate 4, and second fins 404 are provided in the second cavities 403. The second cavities 403 are connected with connecting pipes 8, and the second cavities 403 are connected with the water inlet 304 and the water outlet 307 through the connecting pipes 8. The cooling water enters the second copper plate 4 from one of the second cavities 403, and then flows from the connecting pipes 8 to the first copper plate 3. The cooling water absorbs heat through the first copper plate 3 and then returns to the other second cavity 403, and finally discharges from the second copper plate 4. The second fins 404 increase the contact area between the second copper plate 4 and the cooling water, thereby increasing the heat exchange efficiency.

[0035] The backs of the first copper plate 3 and the second copper plate 4 are both provided with openings for exposing the first cavity 302 and the second cavity 403. The first sealing plate 301 is welded and fixed at the opening of the first copper plate 3, and the second sealing plate 401 is welded and fixed at the opening of the second copper plate 4. In order to facilitate the processing of the structures in the first cavity 302 and the second cavity 403, the openings are provided. After the processing is completed, the first sealing plate 301 and the second sealing plate 401 are welded and fixed at the openings to close the openings.

[0036] The first sealing plate 301 and the second sealing plate 401 are both made of copper, so that the first sealing plate 301 and the second sealing plate 401 can be conveniently welded and fixed on the first copper plate 3 and the second copper plate 4 .

[0037] The back of the base plate 1 is provided with a receiving groove for placing the connecting tube 8. The connecting tube 8 is placed in the receiving groove to prevent the connecting tube 8 from protruding from the back of the base plate 1, so that the base plate 1 can be placed stably.

[0038] A cover plate 6 for covering the receiving groove is detachably connected to the back of the base plate 1. The cover plate 6 shields and protects the connecting pipe 8.

[0039] The first copper plate 3 and the second copper plate 4 are detachably connected to the substrate 1 , so as to facilitate the subsequent disassembly, assembly and replacement of the first copper plate 3 and the second copper plate 4 .

[0040] The second copper plate 4 is connected to two quick-release connectors 5, and the two quick-release connectors 5 are respectively connected to the two second cavities 403. One of the second cavities 403 is provided with a first inlet 402 and a first outlet 405, and the other second cavity 403 is provided with a second inlet 406 and a second outlet 407. The quick-release connectors 5 are respectively installed on the first inlet 402 and the second outlet 407, and the connecting pipe 8 is connected to the first outlet 405 and the second inlet 406. The quick-release connector 5 can quickly connect the substrate 1 to the cooling water delivery pipeline, and also facilitate the disassembly between the substrate 1 and the delivery pipeline. The cover plate 6, the first copper plate 3 and the second copper plate 4 are all connected to the substrate 1 by screws 7. The setting of the protrusion 306 can also provide an installation position for the screw 7, thereby facilitating the installation of the screw 7 on the first copper plate 3.

[0041] like Figure 6 As shown, the quick connector 5 includes a tube body 501, one end of which is provided with a threaded portion 505, the other end of the tube body 501 is fixedly sleeved with a conical head 502, a nut 504 is fixedly sleeved on the tube body 501 and located between the threaded portion 505 and the conical head 502, and an annular groove 503 is opened on the tube body 501 and located between the nut 504 and the conical head 502.

[0042] The tube body 501 is threadedly connected to the second copper plate 4 through the threaded portion 505. The quick-release connector 5 can be plugged and snapped onto the quick-release socket on the cooling water delivery pipe through the annular groove 503. The conical head 502 facilitates the insertion of the tube body 501 into the quick-release socket. The nut 504 facilitates the use of tools to rotate the tube body 501, thereby tightening the tube body 501 on the second copper plate 4.

[0043] The connecting pipe 8 is a copper pipe, which can transfer part of the heat of the cooling water to the substrate 1, and then transfer the heat from the substrate 1 to the air.

[0044] The base plate 1 is made of aluminum material, which can reduce the weight of the entire water-cooling plate and facilitate transportation.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
