[0030] Please refer to Figure 1 and Figure 2 , this embodiment provides a ceramic heating component 200, the ceramic heating component 200 includes a heating body 210 and at least one ceramic heating element 220;

[0031] The heating body 210 is provided with at least one fluid channel 211, and the ceramic heating element 220 is accommodated in the fluid channel 211;

[0032] At least one side surface of the ceramic heating element 220 is configured with a metal sintered layer 221 .

[0033] Please refer to Figure 1 and Figure 2 The working principle of the ceramic heating component 200 is:

[0034] The ceramic heating assembly 200 includes a heating body 210 and at least one ceramic heating element 220; the heating body 210 is provided with at least one fluid channel 211, and the ceramic heating element 220 is accommodated in the fluid channel 211; wherein, at least one side of the ceramic heating element 220 is provided with a metal sintered layer 221. Thus, in this way, when the ceramic heating element 220 is accommodated in the fluid channel 211, it can directly contact with the heat-conducting medium in the fluid channel 211, thereby improving the efficiency of heat transfer and further improving the heating efficiency; and at least one side of the ceramic heating element 220 is provided with a metal sintered layer 221, and through the provision of the metal sintered layer 221, the thermal resistance in the process of heat transfer from the ceramic heating element 220 to the heat-conducting medium can be reduced, and the heat transfer efficiency can also be improved;

[0035] In summary, the ceramic heating component 200 accommodates the ceramic heating element 220 in the fluid channel 211, thereby making the ceramic heating element 220 directly contact with the heat-conducting medium in the fluid channel 211, and a metal sintered layer 221 is configured on at least one side of the ceramic heating element 220, thereby effectively reducing the thermal resistance in the heat transfer process, improving the heat transfer efficiency, and thus improving the heating efficiency and reducing the heating energy consumption.

[0036] It should be noted that when the ceramic heater 220 is placed in the fluid channel 211, in order to enable the ceramic heater 220 to be electrically connected to the structure outside the fluid channel 211, a hole structure can be opened on the heating body 210 for the electrical connection line electrically connected to the ceramic heater 220 to pass through, or the electrical connection line electrically connected to the ceramic heater 220 can be extended out of the fluid channel 211 from the inlet or outlet of the fluid channel 211.

[0037] For further information, please refer to Figure 1 and Figure 2 In the present embodiment, a ceramic heater 220 is provided in each fluid channel 211 for illustration; in other embodiments of the present invention, when the size of the fluid channel 211 is larger than the ceramic heater 220, a plurality of ceramic heaters 220 may be provided in each fluid channel 211, and the plurality of ceramic heaters 220 may be provided in sequence along the extension direction of the fluid channel 211. Alternatively, the size of the ceramic heater 220 may be adjusted to adapt to the size of the fluid channel 211.

[0038] It can be seen from the above content that this embodiment is to place the ceramic heating element 220 in the fluid channel 211, so that the ceramic heating element 220 is in direct contact with the heat-conducting medium in the fluid channel 211, and a metal sintered layer 221 is arranged on at least one side of the ceramic heating element 220, so as to effectively reduce the thermal resistance in the heat transfer process, improve the heat transfer efficiency, and thus improve the heating efficiency. On this basis, at least one group of heat-conducting fins 230 can be arranged in each fluid channel 211, and the heat-conducting fins 230 are connected to the ceramic heating element 220 located in the same fluid channel 211. In this way, the efficiency of heat exchange between the heat-conducting medium in the fluid channel 211 and the ceramic heating element 220 can be increased, thereby improving the heating efficiency of the heat-conducting medium in the fluid channel 211.

[0039] When configuring the thermal fins 230, the thermal fins 230 can be extended along the extension direction of the fluid channel 211. The purpose is to increase the continuous heat exchange between the thermal medium and the thermal fins 230 during the flow of the fluid channel 211, thereby improving the heating efficiency.

[0040] In addition, in this embodiment, when configuring the thermal fins 230, two groups of thermal fins 230 are configured in each fluid channel 211. The two groups of thermal fins 230 are connected to the ceramic heating element 220 located in the same fluid channel 211 and are distributed on opposite sides of the ceramic heating element 220.

[0041] Moreover, it can be known from the above content that by configuring a metal sintered layer 221 on at least one side of the ceramic heater 220, the thermal resistance in the heat transfer process can be effectively reduced and the heat transfer efficiency can be improved. Therefore, on the basis that the thermal fins 230 are connected to the two opposite sides of the ceramic heater 220, the two sides of the ceramic heater 220 used to connect with the thermal fins 230 can be configured with a metal sintered layer 221. In this way, the thermal resistance in the heat transfer process between the two sides of the ceramic heater 220 and the thermal fins 230 and the heat-conducting medium can be reduced, thereby improving the heating efficiency.

[0042] It should be noted that, in this embodiment, when installing the heat-conducting fins 230 , the heat-conducting fins 230 and the metal sintered layer 221 of the ceramic heating element 220 may be connected by welding.

[0043] For further information, please refer to Figure 1 and Figure 2 In this embodiment, when configuring the heating body 210, the heating body 210 may include a plurality of guide plates 212, each of which is provided with a fluid channel 211. In other embodiments of the present invention, the heating body 210 may also adopt other types of structures.

[0044] On the basis of the above-mentioned guide plate 212, the heating body 210 further includes a liquid inlet pipe 213 and a liquid outlet pipe 214. Each guide plate 212 is provided with an inlet and an outlet. The liquid inlet pipe 213 and the liquid outlet pipe 214 are connected to one or more guide plates 212, and each inlet is communicated with the liquid inlet pipe 213, and each outlet is communicated with the liquid outlet pipe 214. Moreover, when the inlet and the outlet are configured, the direction from the inlet to the outlet is the extension direction of the fluid channel 211. Based on this, the ceramic heating element 220 can be located between the inlet and the outlet. Through such a setting, the heat-conducting medium in the fluid channel 211 can continuously exchange heat with the ceramic heating element 220 and the heat-conducting fins 230 when flowing from the inlet to the outlet, thereby improving the heating efficiency.

[0045] Based on the above content, this embodiment also provides a car heating system, which includes the above ceramic heating assembly 200. The car heating system can effectively reduce thermal resistance by adopting the above ceramic heating assembly 200, and can reduce heating energy consumption while improving heating efficiency.

[0046] 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.
