[0032] Please refer to Figure 1-Figure 4 , this embodiment provides a MCH ceramic heating component 100, the MCH ceramic heating component 100 includes an MCH ceramic heating body 110, a connecting member 120 and two metal plates 130;

[0033] A sintered metal layer is provided on the surface of the MCH ceramic heating body 110, and the sintered metal layer is used for welding with the metal plate 130; the MCH ceramic heating body 110 is arranged between the two metal plates 130 and is welded to the two metal plates 130; the connecting member 120 is spaced apart from the MCH ceramic heating body 110, the connecting member 120 is connected to the two metal plates 130, and the area where the connecting member 120 is connected to the metal plate 130 is located outside the area where the metal plate 130 is welded to the MCH ceramic heating body 110.

[0034] Please refer to Figure 1-Figure 4The working principle of the MCH ceramic heating element 100 is:

[0035] The purpose of the MCH ceramic heating assembly 100 is to suppress the deformation of the metal plate 130 during the welding connection process with the MCH ceramic heating body 110 through the setting of the connecting member 120, so as to avoid the deformation stress of the metal plate 130 acting on the MCH ceramic heating body 110 and causing damage to the MCH ceramic heating body 110, thereby ensuring the normal progress of the welding process, improving the production yield, and reducing the processing cost;

[0036] Specifically, to achieve the above purpose, the present embodiment adopts a method of arranging a connecting member 120 between two metal plates 130, and the connecting member 120 is arranged at an interval with the MCH ceramic heating body 110, the connecting member 120 is connected to the two metal plates 130, and the area where the connecting member 120 and the metal plate 130 are connected is located outside the area where the metal plate 130 is welded to the MCH ceramic heating body 110, therefore, the connecting member 120 can be connected to the area where the two metal plates 130 are not welded to the MCH ceramic heating body 110, so that the areas of the two metal plates 130 that are not welded to the MCH ceramic heating body 110 are connected under the connecting action of the connecting member 120. , can interact with each other, and further limit the deformation caused by heat during the welding process, that is, can reduce the deformation of the two metal plates 130 during the welding connection with the MCH ceramic heating body 110, thereby reducing its deformation and further reducing its deformation stress, thereby avoiding the deformation stress of the metal plate 130 acting on the MCH ceramic heating body 110 and causing damage to the MCH ceramic heating body 110, thereby, can ensure the normal progress of the welding process and improve the welding quality, while reducing the probability of damage to the MCH ceramic heating body 110, thereby improving the yield of the MCH ceramic heating component 100 and reducing the processing cost of the MCH ceramic heating component 100.

[0037] It should be noted that, in the embodiment of the utility model, the metal plate 130 can be used as a heat conductor to conduct the heat generated by the MCH ceramic heating body 110, or as one of the components of other structures. For example, the metal plate 130 can be used to cooperate with other structures to form a heat exchange flow channel. In addition, when configuring the connector 120, the method of configuring it at the opposite ends of the MCH ceramic heating component 100 is adopted, that is, the method of suppressing the deformation of the opposite ends of the MCH ceramic heating component 100.

[0038] For further information, please refer to Figure 1-Figure 4In this embodiment, based on the structural setting of the above-mentioned connecting member 120, the two metal plates 130 are both provided with a structural reinforcement part 140, and the structural reinforcement part 140 is located outside the area where the metal plate 130 is welded to the MCH ceramic heating body 110. That is, by setting the structural reinforcement part 140, the structural strength of the part outside the area where the metal plate 130 is welded to the MCH ceramic heating body 110 can be enhanced, so that the anti-deformation ability of the metal plate 130 can be enhanced, so that the deformation of the metal plate 130 during the welding process can be reduced, and the deformation stress of the metal plate 130 can be prevented from acting on the MCH ceramic heating body 110 and causing damage to the MCH ceramic heating body 110. Therefore, the normal progress of the welding process can be ensured and the welding quality can be improved, while the probability of damage to the MCH ceramic heating body 110 can be reduced, so that the yield rate of the MCH ceramic heating component 100 can be improved and the processing cost of the MCH ceramic heating component 100 can be reduced.

[0039] When the structural reinforcement part 140 is configured, it is located in the area where the metal plate 130 is not welded to the MCH ceramic heating body 110, and its purpose is to enhance the structural strength of the metal plate 130 in this area and improve its anti-deformation ability. Therefore, the structural reinforcement part 140 can extend along the length or width direction of the metal plate 130. And the structural reinforcement part 140 includes a protrusion 141 protruding from the metal plate 130, or a concave part concave to the inner side of the metal plate 130.

[0040] Based on the above structure settings, please refer to Figure 1 and Figure 2 In this embodiment, when configuring the connector 120, the connector 120 can be connected to the structural reinforcement parts 140 of the two metal plates 130. Specifically, the connector 120 includes a main body 121, a first connector 122 and a second connector 123. The first connector 122 and the second connector 123 are both connected to the main body 121, and the first connector 122 and the second connector 123 are detachably connected to the metal plates 130 located on both sides of the MCH ceramic heating body 110. The first connector 122 and the second connector 123 are detachably connected to the structural reinforcement parts 140 on the metal plates 130 located on both sides of the MCH ceramic heating body 110.

[0041] Thus, the structural setting of the connecting member 120 can be combined with the structure of the structural reinforcement part 140 to improve the comprehensive deformation resistance of the MCH ceramic heating component 100, thereby enhancing the deformation resistance of the metal plate 130, thereby reducing the deformation of the metal plate 130 during the welding process, and avoiding the deformation stress of the metal plate 130 acting on the MCH ceramic heating body 110 and causing damage to the MCH ceramic heating body 110. Therefore, it can ensure the normal progress of the welding process and improve the welding quality, while reducing the probability of damage to the MCH ceramic heating body 110, thereby improving the yield of the MCH ceramic heating component 100 and reducing the processing cost of the MCH ceramic heating component 100.

[0042] When the first connection part 122 and the second connection part 123 are detachably connected to the structural reinforcement part 140 on the metal plate 130 located on both sides of the MCH ceramic heating body 110, there are many ways of setting, such as setting a threaded connector 120 and a buckle structure. In this embodiment, in order to improve the operation efficiency, the structural reinforcement part 140 includes a protrusion 141 protruding from the metal plate 130, and the protrusion 141 is provided with a slot 142, which is parallel to the metal plate 130; the slot 142 is used to be connected with the first connection part 122 or the second connection part 123. And the slot 142 is a through slot for a part of the first connection part 122 or the second connection part 123 to pass through. Therefore, the first connecting part 122 and the second connecting part 123 can be respectively inserted into the slots 142 of the protruding parts 141 on the metal plate 130 on both sides of the MCH ceramic heating body 110, so as to quickly complete the installation of the connecting part 120, thereby improving the operating efficiency.

[0043] It should be noted that the above content is described by taking the method in which the connecting member 120 is arranged between the two metal plates 130 as an example. In other embodiments of the present invention, please refer to Figure 3 and Figure 4When configuring the connector 120, the connector 120 can also be located outside the two metal plates 130. Specifically, the connector 120 includes a clamping plate 124, and the clamping plate 124 includes a first limiting portion 125, a second limiting portion 126 and a positioning plate 127; the first limiting portion 125 and the second limiting portion 126 are both connected to the positioning plate 127, and the first limiting portion 125 and the second limiting portion 126 are arranged in parallel and spaced apart; the positioning plate 127 is used to abut against the ends of the metal plates 130 on both sides of the MCH ceramic heating body 110; the first limiting portion 125 and the second limiting portion 126 are used to abut against the metal plates 130 on both sides of the MCH ceramic heating body 110, and the portions where the first limiting portion 125 and the second limiting portion 126 abut against the metal plates 130 are both located on the side of the metal plates 130 away from the MCH ceramic heating body 110. Therefore, through such a setting, the clamping plate 124 can be connected to the ends of the two metal plates 130, and its positioning plate 127 is abutted against the ends of the metal plates 130 on both sides of the MCH ceramic heating body 110, while the first limiting portion 125 and the second limiting portion 126 are respectively pressed on the outer sides of the metal plates 130 on both sides of the MCH ceramic heating body 110, thereby limiting their deformation. Such a structural setting is simple and convenient to operate, and can improve the welding efficiency while achieving the above-mentioned purpose.

[0044] Moreover, when the thickness of the MCH ceramic heating body 110 is different or changes, the interval between the two metal plates 130 will change accordingly. Therefore, in order to adapt to the intervals between different metal plates 130, a sliding connection groove can be provided on the positioning plate 127, and the first limiting portion 125 and the second limiting portion 126 are both slidably connected to the sliding connection groove, that is, the first limiting portion 125 and the second limiting portion 126 can slide relative to the sliding connection groove, thereby changing the interval distance between the first limiting portion 125 and the second limiting portion 126 to increase the range of the MCH ceramic heating component 100 that it is adapted to.

[0045] 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.
