Description

Technical Field

[0001] This utility model relates to the field of thermal management technology, and more specifically, to a grounding structure and heater with metal inserts. Background Technology

[0002] The ceramic heater (MCH) is a liquid heater that uses ceramic heating materials as its heating element. Compared to heaters currently on the market, it abandons the heating methods of PTC heaters (positive temperature coefficient thermistors) and stainless steel thick-film (nickel-chromium alloy) heaters. The MCH heater directly contacts the liquid with the ceramic heating element, avoiding heat loss and increasing the heat conversion efficiency to over 98%. It also ensures that the surface temperature of the product is below 100°C, preventing burns from contact.

[0003] MCH can provide solutions for air conditioning thermal management and battery thermal management in new energy vehicles, as well as thermal management solutions for energy storage devices. It boasts advantages such as high energy density and high safety, improving the driving range of new energy vehicles. Currently, other heaters on the market often suffer from poor sealing between the heating element and the main body, posing a risk of leakage with long-term use. Furthermore, the heaters contain numerous wiring harnesses for water temperature sensors, positive and negative electrodes, interfaces, low-voltage interfaces, and protectors, posing a risk of wire damage.

[0004] However, existing ceramic heaters either lack a grounding structure or have a complex grounding structure, which affects the overall safety and reliability of the thermal management system. Utility Model Content

The extension plate is electrically connected to the grounding screw.

[0012] In an optional implementation, the connecting plate and the extension plate are parallel to each other.

[0013] In an optional embodiment, the transition plate is perpendicular to the connecting plate and the extension plate, respectively.

[0014] In an optional embodiment, the transition plate is connected to the connecting plate and the extension plate by a circular arc transition.

[0015] In an optional embodiment, the heater includes a housing; the housing is provided with a protrusion having a slot, and the extension plate can be engaged in the slot.

[0016] In an optional embodiment, the extension plate is provided with a connection through hole; the grounding screw can be disposed in the connection through hole so that the grounding screw is electrically connected to the extension plate.

[0017] In an optional embodiment, the protrusion is provided with a mating through hole, which penetrates both sides of the slot;

[0018] After the extension plate is snapped into the slot, the connecting through hole can be aligned with the mating through hole so that the grounding screw passes through the connecting through hole and is then securely connected to the mating through hole.

[0019] In an optional embodiment, the protrusion is located on the outside of the housing, and the slot extends from the inner wall of the housing into the protrusion.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a grounding structure 10 with a metal insert, which cooperates with the heating core 21 of the heater, including:

[0037] Metal insert 100 and grounding screw 200;

[0038] The metal insert 100 includes a connecting plate 110, a transition plate 120, and an extension plate 130 connected in sequence;

[0039] The connecting plate 110 is located at the bottom of the heating core 21;

[0040] The extension plate 130 is connected to the connecting plate 110 via the transition plate 120. The extension plate 130 is located on the side of the connecting plate 110 away from the heating core 21, and the extension plate 130 extends away from the connecting plate 110 and the transition plate 120.

[0041] The extension plate 130 is electrically connected to the grounding screw 200.

[0042] The grounding structure 10 of this solution, which uses a metal insert, includes a connecting plate 110, a transition plate 120, and an extension plate 130. The connecting plate 110 can connect to the metal heating core 21, while the extension plate 130 can connect to the grounding screw 200, which is conductive to the vehicle frame. This grounding achieves grounding of the heating core side, thereby connecting the heater to the vehicle frame and ensuring the safety and reliability of the heater and the entire thermal management system. Furthermore, the extension plate 130 extends away from the connecting plate 110 and the transition plate 120; this arrangement reduces the height of the metal insert 100 and avoids interference between the metal insert 100 and other components. This results in a grounding structure that is simple in structure, easy to install, and provides excellent grounding performance.

[0043] Please refer to further information. Figure 1 , Figure 2 , Figure 3 and Figure 4 To understand more structural details of the grounding structure 10 with the metal insert, the connecting plate 110, transition plate 120, and extension plate 130 are integrally formed metal plates, and the thickness of the connecting plate 110, transition plate 120, and extension plate 130 is approximately the same. This facilitates the processing and manufacturing of the metal insert 100.

[0044] As can also be seen from the figure, the area of ​​the connecting plate 110 is larger than that of the transition plate 120 and the extension plate 130. This allows for better grounding of the heating core 21.

[0045] In an optional embodiment, the transition plate 120, connecting plate 110, and extension plate 130 all have included angles. This causes the connecting plate 110 and extension plate 130 to be staggered, thereby avoiding interference with other components. It is easy to understand that in other embodiments of this utility model, the transition plate 120, connecting plate 110, and extension plate 130 may also be partially or completely coplanar, or partially maintain included angles. Those skilled in the art should be able to make reasonable choices and designs according to actual needs, and no specific limitations are made here.

[0046] In an optional embodiment, the connecting plate 110 and the extension plate 130 are parallel to each other. This allows the metal insert 100 to extend horizontally, thereby reducing the height of the metal insert 100 and avoiding interference with other components. It is easy to understand that in other embodiments of this invention, the connecting plate 110 and the extension plate 130 may not be parallel; this is merely an example and is not intended to limit the specific implementation.

[0047] In an optional embodiment, the transition plate 120 is perpendicular to both the connecting plate 110 and the extension plate 130. Further, in an optional embodiment, the transition plate 120 is connected to both the connecting plate 110 and the extension plate 130 via an arc transition. This facilitates a stable connection between the various plates of the metal insert 100, ensuring the structural stability and reliability of the metal insert 100. It is readily understood that in other embodiments of this invention, the transition plate 120 may be perpendicular to either the connecting plate 110 or the extension plate 130, or the transition plate 120 may not be perpendicular to either the connecting plate 110 or the extension plate 130. Regarding the angles between the transition plate 120, the connecting plate 110, and the extension plate 130, those skilled in the art should be able to make reasonable selections and designs according to actual needs; no specific limitations are imposed here. Figure 4 It can also be seen that, in an optional embodiment, the heater includes a housing 300; a protrusion 310 is provided on the housing 300, and a groove 311 is provided in the protrusion 310, into which the extension plate 130 can be engaged. This ensures that the metal insert 100 can be stably installed. This design improves upon the existing housing 300 to achieve a more secure connection for the metal insert 100, resulting in lower cost and better connection stability.

[0048] In an optional embodiment, the extension plate 130 is provided with a connection through hole 131; the grounding screw 200 can be disposed in the connection through hole 131 so that the grounding screw 200 is electrically connected to the extension plate 130. That is, grounding is achieved by directly connecting the metal insert 100 to the grounding screw 200, which is beneficial to the stability and reliability of the grounding structure.

[0049] In an optional embodiment, the protrusion 310 is provided with a mating through hole 312, which penetrates both sides of the slot 311. After the extension plate 130 is engaged with the slot 311, the connecting through hole 131 can be directly aligned with the mating through hole 312, so that the grounding screw 200 passes through the connecting through hole 131 and is fastened to the mating through hole 312. That is, the protrusion 310 here serves as both a connection point for the extension plate 130 to engage and a connection point for the grounding screw 200 to be fastened to the housing 300.

[0050] In an optional embodiment, the protrusion 310 is located on the outside of the housing 300, and the slot 311 extends from the inner wall of the housing 300 into the protrusion 310. This arrangement avoids interference with the internal storage space of the housing 300.

[0051] from Figure 3 and Figure 4 It can also be seen that, in an optional embodiment, the grounding structure 10 with metal inserts further includes a support post 410 and a connector; the support post 410 is disposed on the housing 300 and has a fastening through hole 411; the extension plate 130 has a fixing hole 132; the connector passes through the fastening through hole 411 and connects to the fixing hole 132, so that the extension plate 130 is fixed to the housing 300. The mating direction of the support post 410 and the connector makes the connection between the extension plate 130 and the housing 300 more stable, thereby ensuring the reliability of the grounding function of the grounding structure.

[0052] Secondly, this utility model provides a heater, which includes a grounding structure 10 with a metal insert as described in any of the foregoing embodiments.

[0053] In summary, this utility model embodiment provides a grounding structure 10 with metal insert and a heater, which has at least the following advantages:

[0054] The grounding structure connection plate 110 can be connected to the metal heating core 21, while the extension plate 130 can be connected to the grounding screw 200, which can be connected to the frame, thereby grounding the heater core side and connecting the heater to the frame, thus ensuring the safety and reliability of the heater and the entire thermal management system.

[0055] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
