Description

Technical Field

[0001] This utility model relates to the field of pulse heater technology, specifically to a ceramic pulse heater. Background Technology

[0002] A pulse heater is a device that uses Joule heat generated by passing a pulsed current through a high-resistivity material (such as molybdenum or titanium) to heat it. Currently, pulse heaters are commonly used in welding processes.

[0003] In existing technologies, pulse heaters exhibit relatively slow heating and cooling rates during the welding of components, making them unsuitable for welding certain parts. Slow heating rates during welding reduce efficiency, prolong production time, and lower productivity. Slow cooling rates, on the other hand, often negatively impact weld quality, leading to high defect rates and reduced production efficiency. Current pulse heaters typically heat up at approximately 30°C per second and cool down at approximately 10°C per second, failing to meet the demands of rapid heating and cooling in production processes. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a ceramic pulse heater that can heat up and cool down quickly, thus solving the need for rapid heating and cooling in welding processes.

[0007] It also includes a vacuum adsorption connector for adsorbing the ceramic heating plate onto the upper surface of the intermediate partition, and a cooling connector for adsorbing the intermediate partition onto the upper surface of the heat-insulating platform.

[0008] The ceramic heating plate is made of high-density ceramic material.

[0009] Furthermore, both the base and the heat insulation platform are provided with adsorption through holes, and the vacuum adsorption connector is connected in sequence to the adsorption through holes of the base and the heat insulation platform.

[0010] Furthermore, both the base and the heat insulation platform are provided with air flow holes, and the cooling connector is connected in sequence to the air flow holes of the base and the heat insulation platform.

[0011] Furthermore, the number of vacuum adsorption connectors is set to two; and / or

[0012] The number of cooling joints is set to three.

[0013] Furthermore, the ceramic pulse heater also includes a K-type thermocouple electrically connected to the ceramic heating plate, and the K-type thermocouple is fixed to one side of the base by a thermocouple fixing plate and fasteners.

[0014] Furthermore, positioning pins for positioning the heat insulation platform and the ceramic heating plate are provided at each of the four corners of the base.

[0015] Furthermore, a protective fitting is provided on one side of the heat insulation platform.

[0016] Furthermore, the upper part of the protective hardware is also provided with an inverted L-shaped protective positioning hardware.

[0017] Furthermore, exhaust adjustment plates are provided on both sides of the heat insulation platform, and the exhaust adjustment plates are provided with exhaust through holes.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) The ceramic pulse heater of this utility model uses a ceramic heating plate to heat the tool to be welded.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention, the embodiments, and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0030] The following description is based on specific embodiments. Example 1

[0031] A ceramic pulse heater, such as Figures 1 to 4 As shown, it includes a base 4, a heat-insulating platform 3 disposed on the base 4, a ceramic heating plate 1 disposed above the heat-insulating platform 3, and an intermediate partition 2 disposed between the heat-insulating platform 3 and the ceramic heating plate 1; it also includes a first vacuum adsorption joint 10 and a second vacuum adsorption joint 11 for adsorbing the ceramic heating plate 1 onto the upper surface of the intermediate partition 2, and a first cooling joint 12, a second cooling joint 16 and a third cooling joint 17 for adsorbing the intermediate partition 2 onto the upper surface of the heat-insulating platform 3.

[0032] Both the base 4 and the heat insulation platform 3 are provided with adsorption through holes. The first vacuum adsorption connector 10 and the second vacuum adsorption connector 11 are connected to the adsorption through holes of the base 4 and the heat insulation platform 3 in sequence.

[0033] Both the base 4 and the heat insulation platform 3 are provided with air flow holes. The first cooling joint 12, the second cooling joint 16 and the third cooling joint 17 are connected to the air flow holes of the base 4 and the heat insulation platform 3 in sequence.

[0034] The ceramic pulse heater also includes a K-type thermocouple 7 electrically connected to the ceramic heating plate 1. The K-type thermocouple 7 is fixed to one side of the base 4 by a thermocouple fixing plate 5 and fasteners 8. The K-type thermocouple 7 is used to detect the temperature of the ceramic heating plate 1.

[0035] The base 4 is provided with positioning pins 9 at each of its four corners for positioning the heat insulation platform 3 and the ceramic heating plate 1, thereby ensuring that the heat insulation platform 3 and the ceramic heating plate 1 are installed securely.

[0036] Among them, a protective fitting 14 is provided on one side of the heat insulation platform 3. The protective fitting 14 is used to provide heating protection when the ceramic heating plate 1 heats up.

[0037] The upper part of the protective fitting 14 is also provided with an inverted L-shaped protective positioning fitting 13. When heated, the inverted L-shaped protective positioning fitting 13 hooks onto the upper surface of the protective fitting 14, thereby providing better protection.

[0038] The heat insulation base 3 has exhaust adjustment plates 15 on both sides, and each exhaust adjustment plate 15 has an exhaust hole 151. The exhaust hole 151 of the exhaust adjustment plate 15 facilitates the rapid dissipation of heat when the ceramic heating plate 1 cools down.

[0039] The ceramic heating plate 1 is also connected to an electric wire 6 for power supply. The electric wire 6 is fixed to the side of the heat insulation platform 3 and the side of the base 4 respectively.

[0040] In actual installation and application, the ceramic pulse heater is first installed on the base 4, then the thermocouple fixing plate 5 and fasteners 8 are fastened, and the positioning pins 9 are installed. The ceramic heating plate 1 is then connected to the wires 6. The ceramic heating plate 1 is then powered on and heated. The temperature of the ceramic heating plate 1 is detected by the K-type thermocouple 7. At the same time, vacuum adsorption is performed through the first vacuum adsorption joint 10 and the second vacuum adsorption joint 11 to make the ceramic heating plate 1 fit tightly against the intermediate partition plate 2. The heating protection is provided by the protective positioning hardware 13 and the protective hardware 14. When the ceramic heating plate 1 reaches the set temperature, a vacuum airflow is introduced through the first cooling joint 12, the second cooling joint 16 and the third cooling joint 17 to facilitate rapid cooling and heat dissipation of the ceramic heating plate 1. At the same time, rapid heat dissipation is achieved through the exhaust port 151 of the exhaust adjustment plate 15, allowing the ceramic heating plate 1 to cool down rapidly.

[0041] This ceramic pulse heater heats the tool to be welded using a ceramic heating plate 1. The ceramic heating plate 1 has the advantages of rapid heating and good heat dissipation. Furthermore, an intermediate partition 2 is placed between the ceramic heating plate 1 and the heat-insulating base 3. During heating, the partition 2 is in close contact with the lower surface of the ceramic heating plate 1, preventing heat loss and further increasing the heating rate. When cooling is required, a vacuum airflow is introduced through a cooling joint to facilitate heat dissipation and cooling. Therefore, this ceramic pulse heater can heat up and cool down rapidly, with a heating rate of approximately 100°C per second and a cooling rate of approximately 100°C per second, effectively meeting the needs of rapid heating and cooling in welding processes.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
