[0037] The utility model provides a control cabinet for a high-frequency heating furnace, comprising: a sealed cabinet body 11; a water cooling system water distributor 12, the water cooling system water distributor 12 is arranged in the cabinet body 11, and the water cooling system water distributor 12 is provided with a plurality of circulating cooling water pipes; a circulating water cooling radiator 13 for air outlet, the circulating water cooling radiator 13 is installed in the cabinet body 11, and the circulating water cooling radiator 13 comprises a water inlet 131 and a water outlet 132, wherein the water outlet end of one circulating cooling water pipe is connected to the water inlet 131, and the water return end of the same circulating cooling water pipe is connected to the water outlet 132.

[0038] In a specific embodiment, the cabinet 11 can be remade, and during the manufacture, the heat dissipation holes on the cabinet 11 are not processed directly, or the original heat dissipation holes can be blocked by flame retardant foam to make the cabinet 11 airtight. The structure and working principle of the circulating water cooling radiator 13 are within the scope of the prior art and will not be described in detail here.

[0039] In the technical solution proposed in the present application, the original water cooling system water distributor 12 of the control cabinet is utilized to provide circulating cold water to the circulating water cooling radiator 13 through one of the circulating cooling water pipes. The circulating water cooling radiator 13 discharges cold air in the cabinet 11 to cool the interior of the cabinet 11, especially to cool the DC capacitor group 16 and the circuit board in the cabinet 11.

[0040] like Figure 1 As shown, as an embodiment of the control cabinet 1 for a high-frequency heating furnace, the control cabinet 1 for a high-frequency heating furnace also includes: a mounting frame 14, the mounting frame 14 is installed in the cabinet 11, the mounting frame 14 is arranged in the horizontal direction, and the mounting frame 14 is located in the middle part of the height direction of the cabinet 11; a resonant transformer 15; a DC capacitor group 16, the resonant transformer 15 and the DC capacitor group 16 are respectively installed on the top of the mounting frame 14, the resonant transformer 15 and the DC capacitor group 16 are provided with a gap in the horizontal direction, and the circulating water-cooled radiator 13 is installed in the gap.

[0041] The existing gap between the resonant transformer 15 and the DC capacitor group 16 is directly used to install the circulating water cooling radiator 13, which is fast and efficient.

[0042] like Figure 2 As shown, as another embodiment of the control cabinet 1 for a high-frequency heating furnace, a side panel of the cabinet 11 is provided with a first opening, and the cabinet 11 also includes: a mounting frame 14, the mounting frame 14 is installed in the cabinet 11, the mounting frame 14 is arranged in a horizontal direction, and the mounting frame 14 is located in the middle part of the height direction of the cabinet 11; a shell 110, a second opening is provided on one side of the shell 110, the shell is installed on the outside of the first opening, the first opening is sealed and connected with the second opening, and a circulating water-cooled radiator 13 is installed in the shell.

[0043] The circulating water cooling radiator 13 is installed in the housing, which saves space in the cabinet 11 and avoids the components in the cabinet 11 from being arranged too compactly.

[0044] The circulating water-cooled radiator 13 discharges air toward the top thereof. The control cabinet 1 for the high-frequency heating furnace also includes a guide plate 19. One end of the guide plate 19 contacts the top of the second opening. The other end of the guide plate 19 is fixedly connected to the outer shell. The guide plate 19 tilts downward from the end contacting the second opening to the other end. The guide plate 19 is located directly above the circulating water-cooled radiator 13.

[0045] Since the heat in the cabinet 11 is mainly concentrated at the top of the cabinet 11, the circulating water-cooled radiator 13 discharges air directly above it, allowing the cold air to directly contact the area with higher temperature in the cabinet, thereby achieving a better cooling effect. Under the action of the guide plate 19, the cold air can contact the air in the cabinet 11 more quickly, further improving the cooling effect.

[0046] The circulating water-cooling radiator 13 is fixedly connected to the mounting frame 14, and the housing 110 is detachably connected to the first opening. When the circulating water-cooling radiator 13 is inspected and repaired, the housing 110 can be removed. Since the circulating water-cooling radiator 13 is fixedly connected to the mounting frame 14, the circulating water-cooling radiator 13 and the pipes on the circulating water-cooling radiator 13 will not move during the disassembly and assembly of the housing 110.

[0047] The mounting frame 14 is exposed at the first opening, and the side of the circulating water cooling radiator 13 is fixedly connected to the side of the mounting frame 14. The mounting frame 14 is exposed at the first opening, which facilitates the connection between the mounting frame 14 and the circulating water cooling radiator 13.

[0048] The top of the housing 110 is arranged horizontally. During the process of disassembling and assembling the housing 110, since the top of the housing 110 is arranged horizontally, the top of the housing 110 can be used to temporarily place tools used for disassembly and assembly.

[0049] The utility model also provides a high-frequency heating furnace, comprising: the above-mentioned control cabinet 1 for the high-frequency heating furnace, in which a DC capacitor group 16 and an IGBT cooling plate 17 are also arranged; a furnace body 2; and a water-cooling cable 3, wherein the furnace body 2 and the control cabinet 1 for the high-frequency heating furnace are connected via the water-cooling cable 3.

[0050] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
