Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal management technology, and more specifically, to a grounding structure and heater that are fitted with an upper end cover. 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
[0005] The purpose of this utility model includes, for example, providing a grounding structure and heater that fits the upper end cover, the grounding structure of which is simple and reliable, and can ensure a stable grounding arrangement for the heater.
[0006] The embodiments of this utility model can be implemented as follows:
[0007] In a first aspect, this utility model provides a grounding structure for use with an upper end cover, disposed on the upper end cover, comprising:
[0008] First slab, second slab;
[0009] The first plate is disposed on the upper end cover, and the first plate extends in a first direction away from the upper end cover;
[0010] The second plate is disposed on the side of the first plate away from the upper end cover, and the second plate extends in a direction away from the upper end cover and the first plate respectively; the first plate and the second plate have an included angle;
[0011] The second plate has a connection hole; the connection hole can be used to connect to a grounding screw to electrically connect to the frame through the grounding screw.
[0012] In an optional implementation, the first plate and the second plate remain perpendicular.
[0013] In an optional embodiment, the first plate includes an upper plate, a connecting plate, and a lower plate.
[0014] Along the first direction, the upper plate, the connecting plate, and the lower plate are connected in sequence; the top of the upper plate away from the connecting plate is connected to the upper end cover, and the bottom of the lower plate away from the connecting plate is connected to the second plate.
[0015] The connecting plate has an included angle with both the upper plate and the lower plate.
[0016] In an optional embodiment, the upper plate and the lower plate are parallel to each other.
[0017] In an optional embodiment, the connecting plate and the upper plate body maintain an obtuse angle, such that the bottom of the connecting plate extends in a direction away from the upper plate body.
[0018] In an optional embodiment, the connecting plate transitions with the upper plate and the lower plate by an arc.
[0019] In an optional embodiment, the lower plate body and the second plate body have a circular arc transition.
[0020] In an optional embodiment, the first plate and the second plate are integrally formed.

[0023] The beneficial effects of this utility model embodiment include, for example:
[0024] The grounding structure of this design, which is fitted with the upper cover, includes a first plate and a second plate. The first plate is directly connected to the upper cover, while the second plate extends away from both the upper cover and the first plate. The connecting hole in the second plate serves as the connection point for the grounding screw, allowing electrical conductivity between the heater and the vehicle frame. Because the upper cover is made of conductive metal and connects to other metal structures such as the flow channel plate, this design effectively grounds the heater to the vehicle frame, ensuring the safety and reliability of the heater and the entire thermal management system. Furthermore, the angle between the first and second plates avoids interference between the grounding structure and other components and reduces the space occupied by the grounding structure. In summary, this grounding structure with the upper cover offers advantages such as simple structure, easy installation, and excellent grounding performance. Attached Figure Description

[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 This embodiment provides a grounding structure 10 that mates with the upper end cover, disposed on the upper end cover 21, including:
[0037] First plate 100, second plate 200;
[0038] The first plate 100 is disposed on the upper end cover 21, and the first plate 100 extends toward a first direction A away from the upper end cover 21;
[0039] The second plate 200 is disposed on the side of the upper end cover 21 away from the first plate 100, and the second plate 200 extends in a direction away from the upper end cover 21 and the first plate 100 respectively; the first plate 100 and the second plate 200 have an included angle;
[0040] The second plate 200 has a connection hole 210; the connection hole 210 can be used to connect to a grounding screw to make electrical connection with the frame through the grounding screw.
[0041] The grounding structure 10 with this upper cover has a first plate 100 directly connected to the upper cover 21, while the second plate 200 extends away from both the upper cover 21 and the first plate 100. The connecting hole 210 of the second plate 200 serves as the connection point for the grounding screw, allowing electrical connection to the vehicle frame via the grounding screw. Because the upper cover 21 is made of conductive metal and is connected to metal structures such as the flow channel plate, this enables grounding of the heater to the vehicle frame, thus ensuring the safety and reliability of the heater and the entire thermal management system. Furthermore, the angle between the first plate 100 and the second plate 200 avoids interference between the grounding structure and other components, and also reduces the space occupied by the grounding structure. Therefore, the grounding structure 10 with this upper cover has the advantages of simple structure, convenient installation, and good grounding effect.
[0042] Please continue reading. Figure 1 , Figure 2 and Figure 3 To learn more about the structural details of the grounding structure 10 that mates with the upper cover.
[0043] As shown in the figure, the upper cover 21 has a rectangular structure. The grounding structure 10 that mates with the upper cover 21 is located on the outer wall of the upper cover 21, and the grounding structure 10 is located at the corner of the long side of the upper cover 21 near the short side. This further avoids interference with other components.
[0044] It should be noted that the first direction A in this embodiment is the vertical direction perpendicular to the upper cover 21. It is easy to understand that those skilled in the art should be able to make reasonable selections and designs regarding the specific direction of the first direction A according to actual needs. No specific restrictions are made here. For example, the first direction A can also be horizontal, inclined upward, inclined downward, etc., to suit different actual situations. This is just an example. As long as the grounding structure 10 that cooperates with the upper cover extends away from the upper cover 21, it is acceptable. No specific limitation is made.
[0045] Optionally, in this embodiment, the grounding structure 10 that mates with the upper cover can be located at the bottom edge of the upper cover 21.
[0046] In this embodiment, the grounding structure 10 that mates with the upper end cover is directly connected to the grounding screw through the connecting hole 210, thereby making the grounding screw conductive with the vehicle frame and achieving grounding. It should be noted that in other embodiments of this utility model, the grounding structure 10 that mates with the upper end cover can also be electrically connected to the grounding screw via a wire, and then made conductive with the vehicle frame through the grounding screw to achieve grounding. This is merely an example, and the specific implementation is not limited.
[0047] from Figure 1 and Figure 2It can also be seen that both the first plate 100 and the second plate 200 are rectangular plates. In an optional embodiment, the first plate 100 and the second plate 200 are integrally formed. This facilitates the processing, manufacturing, and maintenance of the first plate 100 and the second plate 200, as processing of the first plate 100 and the second plate 200 can be achieved solely through bending operations. Furthermore, the upper end cover 21, the first plate 100, and the second plate 200 can also be integrally formed, thereby further simplifying the processing and manufacturing of the grounding structure.
[0048] In an optional embodiment, the first plate 100 and the second plate 200 have the same thickness. Having the same thickness results in more uniform structural stress between the first plate 100 and the second plate 200, and better overall structural stability of the grounding structure.
[0049] from Figure 1 , Figure 2 and Figure 3 It can also be seen that, in an optional embodiment, the first plate 100 and the second plate 200 remain perpendicular.
[0050] Furthermore, in an optional embodiment, the first plate 100 includes an upper plate 110, a connecting plate 120, and a lower plate 130. Along the first direction A, the upper plate 110, the connecting plate 120, and the lower plate 130 are sequentially connected to the top of the upper end cover 110 away from the connecting plate 120 and connected to the upper end cover 21, and the bottom of the lower plate 130 away from the connecting plate 120 and connected to the second plate 200. The connecting plate 120 has an included angle with both the upper plate 110 and the lower plate 130. That is, the first plate 100 is set as multiple plates arranged in a staggered folding manner, which improves the structural stability of the first plate 100 on the one hand, and avoids interference between the first plate 100 and other components on the other hand.
[0051] In an optional embodiment, the upper plate 110 and the lower plate 130 are parallel to each other. It is easy to understand that in other embodiments of this utility model, the upper plate 110 and the lower plate 130 may also have a preset included angle; this is merely an example and is not intended to limit the scope.
[0052] Furthermore, in an optional embodiment, the connecting plate 120 and the upper plate 110 maintain an obtuse angle, such that the bottom of the connecting plate 120 extends away from the upper plate 110. That is, the upper plate 110 and the lower plate 130 tend to move away from each other, which increases the overall height of the first plate 100, thereby reducing the connection distance with the frame and ensuring the stability of the upper end cover 21 in grounding.
[0053] In an optional embodiment, the connecting plate 120 transitions with the upper plate 110 and the lower plate 130 via an arc. This ensures a uniform stress distribution among the upper plate 110, connecting plate 120, and lower plate 130, thereby improving the structural stability of the first plate 100 and increasing the service life of the grounding structure.
[0054] In an optional embodiment, the lower plate 130 and the second plate 200 have a rounded transition. This results in a more uniform stress distribution throughout the grounding structure, offering advantages such as extended service life.
[0055] In an optional embodiment, the upper plate 110 and the side wall of the upper end cover 21 are arranged coplanarly. This makes the connection between the upper end cover 21 and the first plate 100 more stable, ensuring the stability and reliability of the grounding structure 10 that mates with the upper end cover.
[0056] Secondly, this utility model provides a heater, which includes a grounding structure 10 that is fitted with the upper end cover of any of the foregoing embodiments.
[0057] In summary, this utility model embodiment provides a grounding structure 10 with an upper end cover and a heater, which has at least the following advantages:
[0058] The first plate 100 is directly connected to the upper cover 21, and the second plate 200 is connected to the grounding screw to achieve electrical conductivity with the vehicle frame. Because the upper cover 21 is made of conductive metal and is connected to metal structures such as the flow channel plate, this enables the heater to be grounded to the vehicle frame, thereby ensuring the safety and reliability of the heater and the entire thermal management system.
[0059] Meanwhile, because the first plate 100 and the second plate 200 have an included angle, interference between the grounding structure and other components is avoided on the one hand, and the space occupied by the grounding structure is reduced on the other hand.
[0060] The grounding structure 10 with such an upper cover has the advantages of simple structure, convenient installation and good grounding effect.
[0061] 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.
