Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a heating plate and heating module that can be applied to new energy vehicles. It uses U-shaped fins to conduct heat to the cooling pad, which helps to increase the heating area of the cooling pad and make the heating of the cooling pad more even, thereby improving the heating efficiency and making the overall structure smaller.
[0005] To achieve the above objectives, the specific solution of this utility model is as follows:

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.
[0024] like Figures 1 to 5 As shown, this embodiment relates to a heating module that can be applied to new energy vehicles, including a base 2 and a heating plate 1; the base 2 has a cavity 21; one end of the base 2 is provided with two connection ports 22 that communicate with the cavity 21; the heating plate 1 is located at the opening of the cavity 21.
[0025] The heating plate 1 includes a plate body 11; the plate body 11 may be made of stainless steel; the outer surface of the plate body 11 is provided with a resistance heating layer 12, which is a thick film heating layer; the inner surfaces of the plate body 11 are provided with a plurality of U-shaped fins 13 of different sizes; the plurality of U-shaped fins 13 extend into the cavity 21; the plurality of U-shaped fins 13 are arranged in descending order or ascending order; the center lines of the plurality of U-shaped fins 13 coincide; a plurality of U-shaped flow channels 14 of different sizes are formed between each two adjacent U-shaped fins 13;
[0026] Specifically, in the actual application of the heating module applicable to new energy vehicles in this embodiment, one of the connection ports 22 is set as the inlet and the other connection port 22 is set as the outlet. Cold liquid is introduced into the cavity 21 through the inlet. The cold liquid flows along each U-shaped flow channel 14. At the same time, the resistive heating layer 12 is energized to generate heat. The heat is conducted to each U-shaped fin 13, thereby heating the cold liquid flowing through each U-shaped flow channel 14 and the cold liquid in the cavity 21. The heated cold liquid flows out from the outlet, thereby taking away the heat generated by the heating plate 1.
[0027] In this embodiment, multiple U-shaped fins 13 of different sizes are nested in descending order of size, thereby forming multiple U-shaped flow channels 14 of different sizes between two adjacent U-shaped fins 13. This allows the U-shaped fins 13 to conduct heat to the cooler, increasing the heating area of the cooler and making the heating of the cooler more even, thus improving heating efficiency and reducing the overall structural volume.
[0028] like Figure 3As shown, the heating module of this embodiment, applicable to new energy vehicles, in some implementations, has multiple U-shaped fins 13 symmetrically arranged about the center line of the plate 11. This arrangement allows for more even heating of the cooling system and more thorough heat transfer to the cooling system.
[0029] This embodiment can be applied to the heating module of new energy vehicles. In some embodiments, the plate 11 and the U-shaped fins 13 are made of the same material, namely aluminum, aluminum alloy, or stainless steel. Preferably, in the heating plate 1 of this embodiment, the plurality of U-shaped fins 13 are integrally formed with the plate 11. This arrangement results in higher heat conduction efficiency and higher heat utilization. Alternatively, the plurality of U-shaped fins 13 can be sequentially welded onto the plate 11.
[0030] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment can be applied to the heating module of new energy vehicles. In some embodiments, the resistive heating layer 12 is set on the surface of the plate 11 by screen printing. By using screen printing to bond the resistive heating layer 12 to the surface of the plate 11, the structure is more reliable and the heat conduction efficiency is higher.
[0031] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment can be applied to the heating module of new energy vehicles. In some embodiments, the resistive heating layer 12 is arranged in a reciprocating bending structure on the surface of the plate 11. Specifically, the arrangement position of the resistive heating layer 12 matches the arrangement position of the multiple U-shaped fins 13, so as to quickly transfer the heat generated by the resistive heating layer 12 to the cool air.
[0032] like Figures 1 to 4 As shown, this embodiment can be applied to the heating module of new energy vehicles. In some implementations, the heating plate 1 has first mounting holes 15 evenly distributed around its periphery; the base 2 has second mounting holes 23 corresponding to the first mounting holes 15 around the opening of the cavity 21; the first mounting holes 15 and the second mounting holes 23 are connected by fasteners 3. Specifically, the fasteners 3 are screws. Through the above arrangement, the heating plate 1 can be detachably mounted on the base 2 for easy assembly and disassembly.
[0033] like Figure 2 and Figure 5As shown, this embodiment can be applied to the heating module of new energy vehicles. In some embodiments, a partition strip 24 extends from the middle of one end of the base 2 towards the center of the base 2; the partition strip 24 is located between two connection ports 22; the partition strip 24 extends into the smallest U-shaped fin 13. Through the above arrangement, the two connection ports 22 are separated by the partition strip 24 to prevent cold water entering from the inlet from flowing directly out of the outlet; this allows the cold water to fully absorb heat before flowing out of the outlet, resulting in better heating effect.
[0034] Example 2, as Figures 1 to 5 As shown, the heating module applicable to new energy vehicles in this embodiment differs from that in Embodiment 1 above in that: the plate 11 is made of stainless steel, and the U-shaped fins 13 are made of aluminum or aluminum alloy; the U-shaped fins 13 are welded to the surface of the plate 11. The remaining structure is the same as in Embodiment 1 above. Through the above arrangement, the heating plate 1 is manufactured, and the high thermal conductivity of the U-shaped fins 13 is utilized to promptly conduct heat to the cooling system.
[0035] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
