[0031] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.
[0032] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.
[0033] Please refer to Figures 1 - 3 , this embodiment provides a finned ceramic heater 100, and the finned ceramic heater 100 includes a heater main body 110 and at least one heat-conducting fin group 120;
[0034] The heat-conducting fin group 120 is connected to one side of the heater main body 110 or two opposite sides of the heater main body 110.
[0035] It should be noted that, in this embodiment, the heater main body 110 is an MCH ceramic heater, and the alumina ceramic and the heating wire of the MCH ceramic heater are of a sintered integrated structure.
[0036] Please refer to Figures 1 - 3 , the working principle of the finned ceramic heater 100 is as follows:
[0037] The finned ceramic heater 100 includes a heater main body 110 and at least one heat-conducting fin group 120;
[0038] During its use, since the heat-conducting fin group 120 is connected to one side of the heater main body 110 or two opposite sides of the heater main body 110, thus during the use, the heat generated by the operation of the heater main body 110 can be quickly transferred to the liquid medium in the heater housing in contact with the heat-conducting fin group 120 through the heat-conducting fin group 120 located on one side or both sides of the heater main body 110. Therefore, through the structural setting of the heat-conducting fin group 120, the heat transfer area of the heat transfer region of the heater main body 110 in contact with the liquid medium can be increased, and thus the heat transfer efficiency can be improved, and the heating effect can be enhanced. Moreover, due to the simple structure of the heat-conducting fin group 120, while enhancing the heating effect, it can avoid a sharp increase in the structural weight of the finned ceramic heater 100.
[0039] Furthermore, please refer to Figures 1 - 3 , in this embodiment, when configuring the heat-conducting fin group 120, there are various implementation manners. First, when configuring the heat-conducting fin group 120, in order to increase its contact area with the liquid medium, therefore, when configuring the fin style of the heat-conducting fin group 120, a bent, curved or wavy setting style can be adopted to increase the heat transfer area in contact with the liquid medium; and when it is connected to the heater main body 110, it can be made by an integral molding method with the outer shell of the heater main body 110, or can be made separately and connected by a connection method such as welding, bonding or other detachable connections.
[0040] Specifically, based on the above, the heat-conducting fin group 120 in this embodiment adopts a bent arrangement. Such an arrangement enables the heat-conducting fin group 120 to include a plurality of first heat-conducting fins 121 and a plurality of second heat-conducting fins 122. Among them, the plurality of first heat-conducting fins 121 are connected to the heater main body 110 at intervals and in parallel, and at least one second heat-conducting fin 122 is connected between any two adjacent first heat-conducting fins 121. Thus, through such an arrangement, the heat generated by the heater main body 110 can be transferred to the liquid medium through the first heat-conducting fins 121 and the second heat-conducting fins 122. During the operation of the finned ceramic heater 100, both the first heat-conducting fins 121 and the second heat-conducting fins 122 are in contact with the liquid medium;
[0041] On the basis of the structure provided with the above-mentioned first heat-conducting fins 121 and second heat-conducting fins 122, the heat-conducting fin group 120 in this embodiment further includes a plurality of third heat-conducting fins 123. Each third heat-conducting fin 123 is connected to two adjacent second heat-conducting fins 122, and the first heat-conducting fin 121 and the third heat-conducting fin 123 connected to the same second heat-conducting fin 122 are located at opposite ends of the second heat-conducting fin 122. Moreover, two second heat-conducting fins 122 arranged in parallel are distributed between any two adjacent first heat-conducting fins 121. One end of each of the two second heat-conducting fins 122 is connected to an adjacent first heat-conducting fin 121, and the other ends of the two second heat-conducting fins 122 are both connected to the same third heat-conducting fin 123.
[0042] Through the above structural arrangement, the first heat-conducting fins 121, the second heat-conducting fins 122, and the third heat-conducting fins 123 can be configured into a bent structure, so that through such an arrangement, the contact area between the heat-conducting fin group 120 and the liquid medium can be increased. And when configuring the third heat-conducting fin 123, the third heat-conducting fin 123 can also be bent. It should be noted that when configuring the above-mentioned first heat-conducting fins 121 and third heat-conducting fins 123, the widths of the first heat-conducting fins 121 and the third heat-conducting fins 123 along their arrangement directions can be made inconsistent, the widths of the plurality of first heat-conducting fins 121 can also be made inconsistent, and the widths of the plurality of third heat-conducting fins 123 can be made inconsistent, so that through such an arrangement, the distance between any two adjacent second heat-conducting fins 122 is the same as or different from the distance between other adjacent second heat-conducting fins 122, thereby meeting the heat-conducting requirements in different usage scenarios.
[0043] Further, please refer to Figure 4 and in combination with Figures 1 - 3In the present embodiment, when configuring the structure of the above-mentioned heat-conducting fin group 120, a method of connecting the first heat-conducting sheet 121 to the heater body 110 is adopted. Based on this, when connecting the first heating sheet to the heater body 110, the first heat-conducting sheet 121 can be welded to the heater body 110 or bonded to the heater body 110. In addition, the fin-type ceramic heater 100 can also include a plurality of heat-conducting connecting seats 124, which are connected to the heater body 110 in parallel and at intervals, and each heat-conducting connecting seat 124 is detachably connected to a corresponding first heat-conducting sheet 121.
[0044] That is, according to the above content, when installing the first heat conductive sheet 121, the first heat conductive sheet 121 can be connected to the heater body 110 by welding or bonding, or it can be detachably connected to the heater body 110 by setting a heat conductive connecting seat 124; in addition, it should be noted that when the first heat conductive sheet 121 is detachably connected to the heater body 110 by setting a heat conductive connecting seat 124, different heat conductive fin group 120 structures can be replaced by removing the first heat conductive sheet 121 of the heat conductive fin group 120 from the heat conductive connecting seat 124, so as to select a suitable heat conductive fin group 120 according to the different adaptability of the usage scenarios.
[0045] In addition, when the first heat conductive sheet 121 is bonded to the heater body 110 , a heat conductive gel layer may be disposed between the first heat conductive sheet 121 and the heater body 110 to improve the efficiency of transferring heat generated by the heater body 110 to the first heat conductive sheet 121 through the heat conductive gel layer.
[0046] For further information, please refer to Figures 1 - 3 When configuring the heat-conducting fin group 120, in addition to the above-mentioned structural setting, in other embodiments of the present invention, the heat-conducting fin group 120 may also include a first sub-part and a second sub-part, the first sub-part is connected to the heater body 110, and the second sub-part is detachably connected to an end of the first sub-part away from the heater body 110; wherein the first sub-part and the second sub-part both extend in a direction away from the heater body 110. Thus, in this way, by replacing different second sub-parts, the area of the heat-conducting fin group 120 that can contact the liquid medium can be adjusted to adapt to different usage scenarios.
[0047] Based on the above, please refer to Figures 1 - 4 The utility model provides a vehicle liquid ceramic heater, which comprises a heater housing, a metal flange connecting plate 210 and the above-mentioned fin-type ceramic heater 100;
[0048] A liquid medium is contained within the heater housing. The heat-conducting fin group 120 is contained within the heater housing and is used to be submerged below the liquid level of the liquid medium. The metal flange connecting plate 210 is connected to the heater housing and is also connected to the heater body 110, and the heat-conducting fin group 120 is spaced apart from the metal flange connecting plate 210.
[0049] By adopting the above-mentioned fin-type ceramic heater 100, the vehicle liquid ceramic heater can, through the structural arrangement of the heat-conducting fin group 120, increase the heat transfer area where the heat transfer region of the heater body 110 contacts the liquid medium during the heat transfer process, thereby improving the heat transfer efficiency and the heating effect. Moreover, due to the simple structure of the heat-conducting fin group 120, while enhancing the heating effect, it can avoid a sharp increase in the structural weight of the fin-type ceramic heater 100.
[0050] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
