[0039] Please refer to Figure 1-Figure 3 This embodiment provides a vehicle heat exchange core 100, which includes a flow channel plate group and at least one MCH ceramic heating body 120; at least one heat exchange flow channel is provided in the flow channel plate group, and the heat exchange flow channel is used for the flow of heat exchange medium;

[0040] The MCH ceramic heating body 120 is connected to the flow channel plate group and is in surface contact with the flow channel plate group to exchange heat with the heat exchange medium in the heat exchange flow channel.

[0041] Please refer to Figure 1-Figure 3 The working principle of the vehicle heat exchange core 100 is:

[0042] First, during the use of the vehicle heat exchange core 100, since the MCH ceramic heating body 120 is used as the heating body, the heating efficiency can be improved, and the thickness of the heating body can be reduced. Moreover, the MCH ceramic heating body 120 has good insulation performance, thereby improving the overall insulation of the vehicle heat exchange core 100.

[0043] In addition, when installing the MCH ceramic heater 120, the MCH ceramic heater 120 is connected to the flow channel plate group and is in surface contact with the flow channel plate group, thereby reducing the intermediate heat-conducting material in the process of heat transfer from the MCH ceramic heater 120 to the heat exchange medium in the heat exchange flow channel, thereby reducing the heat transfer thermal resistance;

[0044] Therefore, it can be known from the above content that the vehicle heat exchange core 100 adopts the MCH ceramic heating body 120 and connects it to the flow channel plate group, thereby reducing the intermediate heat conductive material in the process of heat conduction from the MCH ceramic heating body 120 to the heat exchange medium in the heat exchange flow channel, so as to reduce the heat transfer thermal resistance, thereby improving the heating efficiency, and is beneficial to reducing the thickness of the heating body and simplifying the overall structure. It has good insulation properties, thereby improving the overall insulation of the vehicle heat exchange core 100 and reducing the use and production costs.

[0045] For further information, please refer to Figure 1-Figure 3 In the present embodiment, when configuring the flow channel plate group, the flow channel plate group includes a plurality of flow channel units 111, and each flow channel unit 111 is provided with a heat exchange flow channel; the plurality of flow channel units 111 are stacked in sequence, and at least one MCH ceramic heater 120 is correspondingly configured between any two adjacent flow channel units 111. It should be noted that during use, the number of MCH ceramic heaters 120 between two adjacent flow channel units 111 can be adjusted according to the needs of use, and the present embodiment is described by taking an example in which an MCH ceramic heater 120 is provided between two adjacent flow channel units 111. In addition, in other embodiments of the present utility model, the flow channel unit 111 can also be a flat tube structure (such as Figure 4 shown).

[0046] When the MCH ceramic heater 120 is installed between two adjacent flow channel units 111, in order to improve the efficiency of the installation, the surface of each flow channel unit 111 that is used to contact the MCH ceramic heater 120 is provided with a positioning structure 130, and the positioning structure 130 is used to position the MCH ceramic heater 120 corresponding to the flow channel unit 111. It should be noted that the role of the positioning structure 130 is to quickly perform the positioning and installation steps of the MCH ceramic heater 120 when assembling the vehicle heat exchange core 100, and the connection between the MCH ceramic heater 120 and the flow channel unit 111 in the flow channel plate group can be achieved by welding or bonding, and when bonding is used, a thermal conductive gel layer can be provided between the contact surfaces of the MCH ceramic heater 120 and the flow channel unit 111.

[0047] When configuring the positioning structure 130, the positioning structure 130 includes a first positioning portion 131 and a second positioning portion 132; the first positioning portion 131 and the second positioning portion 132 are arranged at intervals and protrude from the side of the flow channel unit 111 for contacting the MCH ceramic heating body 120; the first positioning portion 131 and the second positioning portion 132 are used to abut against the opposite sides of the MCH ceramic heating body 120 corresponding to the flow channel unit 111. Through such a setting, the first positioning portion 131 and the second positioning portion 132 can limit the opposite sides of the MCH ceramic heating body 120, thereby completing the positioning work of the MCH ceramic heating body 120.

[0048] As can be seen from the foregoing, the present embodiment adopts a stacking arrangement of multiple flow channel units 111. Therefore, both sides of the flow channel unit 111 located in the middle are attached with MCH ceramic heating bodies 120. Based on this, in order to simplify the structure of the flow channel unit 111 and realize the versatility of its installation, a first positioning portion 131 and a second positioning portion 132 can be provided on both opposite sides of each flow channel unit 111. When such an arrangement is adopted, when the MCH ceramic heating body 120 between two adjacent flow channel units 111 is installed, due to the first positioning portion 131 of the two adjacent flow channel units 111, the first positioning portion 132 of the two adjacent flow channel units 111 is provided. The positioning portion 131 and the second positioning portion 132 abut against each other, which causes the spacing distance between the two adjacent flow channel units 111 to be too large, resulting in a contact gap between the MCH ceramic heater 120 and the two flow channel units 111. Therefore, twice the height of the first positioning portion 131 and the second positioning portion 132 protruding from the side of the flow channel unit 111 is less than or equal to the thickness of the MCH ceramic heater 120; that is, such a setting method can prevent the first positioning portion 131 and the second positioning portion 132 of the two adjacent flow channel units 111 from affecting the fit between the MCH ceramic heater 120 and the two flow channel units 111.

[0049] For further information, please refer to Figure 1-Figure 3In this embodiment, each flow channel unit 111 includes a heat exchange plate 112 and a shell 113; wherein the heat exchange plate 112 is accommodated in the shell 113 and forms a heat exchange flow channel in the shell 113; along the stacking direction of the multiple flow channel units 111, the shell 113 is provided with a through guide hole group 114, and the guide hole group 114 is connected to the heat exchange flow channel; the first positioning portion 131 includes an annular protrusion 133 arranged around the outer edge of the guide hole group 114, and the second positioning portion 132 includes a strip protrusion 134, and the annular protrusion 133 and the strip protrusion 134 are distributed at opposite ends of the shell 113. By providing the annular protrusion 133 and the strip protrusion 134, the area of ​​each flow channel unit 111 that can be used to fit with the MCH ceramic heater 120 can be limited, and because the annular protrusion 133 is provided around the outer edge of the guide hole group 114, it is possible to avoid the MCH ceramic heater 120 being installed in the area where the guide hole group 114 is located, thereby affecting the stacked installation of multiple flow channel units 111.

[0050] The guide hole group 114 includes a first guide hole 118 and a second guide hole 119 . The first guide hole 118 and the second guide hole 119 are arranged at intervals and are respectively connected to two ends of the heat exchange channel.

[0051] Based on the above structure, please refer to Figure 1-Figure 6 The flow channel plate assembly in this embodiment further includes a first end plate 141, a second end plate 142, a first flow guide tube 143 and a second flow guide tube 144;

[0052] Along the arrangement direction of the plurality of flow channel units 111, the first guide holes 118 of adjacent flow channel units 111 are connected in sequence, the second guide holes 119 of adjacent flow channel units 111 are connected in sequence, and the first end plate 141 and the second end plate 142 are respectively connected to the flow channel units 111 at both ends;

[0053] The first flow guide tube 143 and the second flow guide tube 144 are connected to the first end plate 141, and the first flow guide tube 143 is connected to all the first flow guide holes 118, and the second flow guide tube 144 is connected to all the second flow guide holes 119; the second end plate 142 blocks one end of the first flow guide holes 118 and the second flow guide holes 119 of the flow channel unit 111 adjacent thereto.

[0054] Therefore, by disposing the first end plate 141 , the second end plate 142 , the first flow guide pipe 143 and the second flow guide pipe 144 , the vehicle heat exchange core 100 can be easily connected with the external pipeline.

[0055] As can be seen from the above content, an annular protrusion 133 and a strip protrusion 134 are provided on opposite sides of the shell 113 of each flow channel unit 111, and the side where the flow channel unit 111 is connected to the first end plate 141 and the second end plate 142 does not need to be installed with the MCH ceramic heating body 120. Therefore, the first end plate 141 is provided with a first strip groove 145 for accommodating the strip protrusion 134, and the second end plate 142 is provided with a first circular groove 146 and a second strip groove 147 for accommodating the annular protrusion 133 and the strip protrusion 134. Through such an arrangement, the first end plate 141 and the second end plate 142 can adapt to the structure of the flow channel unit 111 to simplify the overall structure of the vehicle heat exchange core 100.

[0056] 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.
