When the temperature of the heating tube 3 rises, the heat is transferred to the copper-clad layer 4. Since the copper-clad layer 4 has good thermal conductivity, the heat can be quickly transferred to the heat-conducting strips 5. The heat-conducting area is increased by the plurality of heat-conducting strips 5, and the heat-conducting strips 5 transfer the heat Provide a heat-conducting layer 6, which covers the surface of the heating plate body 1, so that the upper surface of the heating plate body 1 is evenly heated, and the contact surface between the material to be processed and the heating plate body 1 is evenly heated, thereby ensuring the processing quality. The heat of the heating plate body 1 is absorbed by heat conduction, and the temperature gradually increases. In a vacuum environment, the heat transfer is more uniform, which can effectively avoid the occurrence of defects such as bubbles and stratification. At the same time, the thermal insulation layer 7 is made of ceramic fiber material. The thermal insulation layer 7 is a fibrous lightweight refractory material with the advantages of light weight, high temperature resistance, good thermal stability, and low thermal conductivity, thereby reducing heat loss to the surrounding environment and improving energy utilization. While ensuring the thermal insulation effect, the overall volume and weight of the heating plate body 1 are reduced, which is convenient for operation and maintenance.

[0025] Referring to Figures 4-5 As shown in the figure, the inside of the heating pipe 3 is fixedly provided with a heating mechanism. The heating mechanism comprises a fixed ring 8 fixedly arranged in the inside of the heating pipe 3. The inside of the fixed ring 8 is fixedly provided with an electric heating tube 9. The electric heating tube 9 and the heating pipe 3 are fixedly provided with a conveying cavity 10. The heating plate body 1 starts to heat the material. At this time, water is injected into the inside of the conveying cavity 10. Then the electric heating tube 9 is electrified to generate heat to heat the water in the inside of the conveying cavity 10. Thus the heat is conveyed to the heating pipe 3. Then the temperature of the heating pipe 3 is increased. The temperature of the heating plate body 1 is continuously monitored by the temperature sensor 11. At the same time, after the heating is completed, the hot water in the inside of the conveying cavity 10 is discharged. Then cold water is injected. Thus the heat of the heating plate body 1 is taken away by the circulating flow of the cold water, thereby saving time and effort.

[0026] Principle of the utility model:

[0027] The utility model discloses a vacuum hot press copper-clad heating plate. When the device is used, the material to be processed is placed on the heating plate body 1 in the working chamber of the vacuum hot press. Then the vacuum hot press outside is started to perform the vacuumizing operation on the working chamber. The air in the working chamber is gradually extracted to form a vacuum environment. The heating plate body 1 starts to heat the material. At this time, water is injected into the inside of the conveying cavity 10. Then the electric heating tube 9 is electrified to generate heat to heat the water in the inside of the conveying cavity 10. Thus the heat is conveyed to the heating pipe 3. Then the temperature of the heating pipe 3 is increased. The heat is transferred to the copper-clad layer 4. Since the copper-clad layer 4 has good heat-conducting performance, the heat can be rapidly transferred to the heat-conducting strip 5. Since the heat-conducting strip 5 is made of a metal matrix composite material, the heat-conducting performance and mechanical strength of the material can be improved. The heat-conducting area is increased by the plurality of heat-conducting strips 5. The heat-conducting strip 5 conveys the heat to the heat-conducting layer 6. The heat-conducting layer 6 covers a layer on the surface of the heating plate body 1. The heat-conducting layer 6 is made of a copper foil material to improve the heating efficiency and uniformity. Thus the upper surface of the heating plate body 1 is uniformly heated. The contact surface of the material to be processed and the heating plate body 1 is uniformly heated. Thus the processing quality is ensured. The heat of the heating plate body 1 is absorbed by the way of heat conduction. The temperature is gradually increased. In the vacuum environment, the heat transfer is more uniform. The generation of defects such as bubbles and delamination can be effectively avoided.

[0028] Meanwhile, the heat insulation layer 7 is made of ceramic fiber material, and the heat insulation layer 7 is a fibrous light-weight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, etc., so as to reduce the heat loss to the surrounding environment, improve the energy utilization rate, and reduce the overall volume and weight of the heating plate body 1 while ensuring the heat insulation effect, facilitating operation and maintenance;

[0029] During the heating process, the temperature sensor 11 continuously monitors the temperature of the heating plate body 1, and it is worth noting that the temperature sensor 11 automatically samples and monitors the ambient temperature in real time, and feeds back the temperature signal to the temperature control system. The temperature control system continuously adjusts the power of the heating element according to the difference between the real-time temperature and the set temperature, so as to realize accurate temperature control, which belongs to the prior art and will not be described in detail in this technical solution.

[0030] After the heating is completed, the hot water inside the conveying cavity 10 is discharged, and then cold water is injected, so as to take away the heat of the heating plate body 1 through the circulating flow of the cold water, thereby facilitating the operation.

[0031] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
