[0002] A vacuum furnace is generally composed of a furnace, an electric heating device, a sealed furnace shell, a vacuum system, a power supply system, and a temperature control system. When the vacuum furnace is working, the temperature inside the furnace is very high, and because the vacuum furnace is in a vacuum state, the gas flows slowly. Even if there is cooling water in the furnace, the gas temperature still drops slowly, which can easily cause the furnace shell to deform after being heated and the sealing material to deteriorate after being heated. When the vacuum furnace is water-cooled, cooling water needs to be continuously injected into the cooling pipe, which not only wastes water resources, but also causes troublesome operation.

[0025] The vacuum furnace body 3 is cooled internally and externally by the primary radiator 1 and the secondary radiator 2, wherein the heat-conducting barrel 202 of the secondary radiator 2 absorbs and guides the heat on the vacuum furnace body 3 to reduce the heat on the vacuum furnace body 3, and at the same time, the heat sink 203 and the water pipe 204 dissipate heat and cool the heat-conducting barrel 202, thereby increasing the heat dissipation and cooling effect of the heat-conducting barrel 202 on the vacuum furnace body 3, wherein a coolant flows in the water pipe 204, and the coolant can absorb the heat on the water pipe 204 when flowing, so the water pipe 204 can absorb heat and cool the heat-conducting barrel 202, and can also absorb the heat on the heat sink 203 simultaneously, and at the same time, the water pipe 204 transports the coolant to the inside of the top ring 205, and then the top ring 205 transports the coolant to each nozzle 206, and the nozzle 206 sprays the coolant on the inner wall of the vacuum furnace body 3, and water-cools the inner wall of the vacuum furnace body 3 to achieve the purpose of cooling the inside and outside of the vacuum furnace body 3.

[0026] The primary radiator 1 includes a base 101, which is installed at the bottom end of the porous barrel 201, and a motor 102 is installed on the base 101. A fan 103 is fixedly connected to the output end of the motor 102, and a protective ring 104 is installed on the outside of the fan 103. The protective ring 104 is located inside the porous barrel 201 and connected to the porous barrel 201;

[0027] The motor 102 is supported by the base 101, and the motor 102 drives the fan 103 to rotate. The fan 103 blows air to cool the vacuum furnace body 3. At the same time, when the wind contacts the bottom of the vacuum furnace body 3, it can be dispersed to the surroundings along the bottom of the vacuum furnace body 3. The wind can contact the secondary radiator 2, and then the water pipe 204 and the heat sink 203 can be blown to dissipate heat, further increasing the heat dissipation effect of the vacuum furnace body 3.

[0028] The vacuum furnace body 3 includes a furnace body 301, which is installed on the inner wall of the heat-conducting barrel 202 and located above the fan 103.

When the cooling liquid flows, it can absorb the heat on the water pipe 204. Therefore, the water pipe 204 can absorb heat and cool the heat-conducting barrel 202, and can also absorb the heat on the heat sink 203 at the same time. The heat sink 203 and the water pipe 204 dissipate heat and cool the heat-conducting barrel 202, thereby increasing the heat dissipation and cooling effect of the heat-conducting barrel 202 on the vacuum furnace body 3. At the same time, the water pipe 204 transports the cooling liquid to the inside of the top ring 205, and then the top ring 205 transports the cooling liquid to each nozzle 206.
