[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0033] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0034] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0035] To address the shortcomings of traditional battery heating systems in terms of efficiency and heating speed, a novel energy storage and automotive liquid heater structure is proposed, such as... Figures 1-6 As shown, it includes:

[0036] The pipe body 6 is provided with a PTC mounting structure 1 and a PTC heating element 2. The PTC heating element 2 is mounted on the PTC mounting structure 1, which ensures that the heating element can be stably and firmly fixed in the heater. The PTC heating element 2 is embedded in the PTC mounting structure 1 of the pipe body 6. By utilizing the self-temperature adjustment function of the PTC element, the heating power is automatically adjusted according to the temperature change, thereby providing a stable and uniform heating effect.

[0037] Chuck 3, two chucks are respectively disposed at both ends of the pipe body 6, the chuck 3 connects to the pipe body 6 and is fixed in the heater system.

[0038] The housing 4 contains the pipe body 6, and the chuck 3 extends from within the housing 4. In practical applications, the energy storage and automotive liquid heater of this application is tightly integrated with the vehicle's air conditioning system, using automotive antifreeze or purified water as the flowing medium within the pipe body 6. The PTC heating element 2 heats the flowing medium through the pipe body 6, thereby increasing the temperature of the medium flowing through the pipe. Notably, this flowing medium not only flows through the pipe body 6 during heating but also works synergistically to cool the battery through the cooling pipes of the vehicle's air conditioning system, effectively preventing the battery temperature from becoming too high and ensuring that the battery operates within its optimal temperature range.

[0039] The outer shell 4 of the pipe body 6 is made of a material with extremely low thermal conductivity. This design effectively reduces heat loss and provides excellent insulation and protection. Furthermore, since the flowing medium is affected by temperature changes, condensation may accumulate on the pipe body. Therefore, by rationally designing the shell 4 for insulation, condensation formation can be effectively reduced. It is particularly important to emphasize that condensation not only affects the appearance of the vehicle's air conditioning system, causing dampness, but may also compromise the product's electrical insulation performance, increasing the risk of electrical leakage. Therefore, preventing condensation accumulation through insulation design not only improves system stability but also ensures vehicle safety.

[0040] In this embodiment, the pipe body 6 and the chuck 3 adopt an integrated aluminum material structure. Aluminum has good thermal conductivity, and the heat generated by the PTC heating core 2 can be efficiently transferred to the circulating medium.

[0041] Furthermore, the PTC mounting structure 1 includes multiple limiting grooves 5, which are disposed on the surface of the pipe body 6. The design of multiple limiting grooves 5 simplifies the assembly of the heater and avoids reliability issues caused by traditional welding and complex assembly processes.

[0042] Furthermore, the bottom surface of the limiting groove 5 is rectangular, and the depth of the limiting groove 5 is the same at all points along the axial direction of the pipe body 6, which ensures that the PTC heating core 2 is uniformly positioned in the pipe and maintains a consistent fixing depth, effectively improving the uniformity of heat conduction and avoiding uneven heat or local overheating caused by insecure fixing or positional deviation.

[0043] Furthermore, multiple limiting grooves 5 are evenly distributed along the circumference of the pipe body 6 to ensure that the PTC heating core 2 is evenly fixed inside the pipe. In addition, this uniform distribution design can avoid the problem of uneven heat distribution caused by unilateral fixing or uneven installation in traditional heaters, effectively improving heat conversion efficiency and heating effect.

[0044] Specifically, four limiting grooves 5 are provided, and the pipe body 6 is cylindrical.

[0045] Furthermore, the outer contour of the end face of the housing 4 is polygonal, and the number of sides of the polygon matches the number of limiting grooves 5, making the connection between the housing 4 and the pipe body 6 tighter and improving the stability of the heater. At the same time, the polygonal outer contour also facilitates placement and positioning.

[0046] Furthermore, the pipe body 6 and the chuck 3 adopt an integrated molding structure, which not only simplifies the production process, but also improves the mechanical strength and structural stability of the product, avoids the common problems of loose connection or joint leakage in traditional heaters, and improves the reliability of the heater during long-term use.

[0047] Furthermore, the inner wall of the pipe body 6 is provided with a special-shaped structure 7, which is used to increase the area of ​​the inner wall of the pipe body 6. By increasing the heat exchange area, the heat transfer speed is improved, the heating time is shortened, and the concentration and uneven distribution of heat in the pipe are effectively avoided.

[0048] Furthermore, the irregular structure 7 is petal-shaped or corrugated, which not only increases the surface area of ​​the inner wall of the pipe, but also effectively enhances thermal convection and mixing when the fluid passes through the pipe, thereby further improving the uniform distribution and transfer efficiency of heat. At the same time, the corrugated or petal-shaped design can also improve the pressure resistance and impact resistance of the pipe, ensuring the stability and durability of the heater in harsh environments.

[0049] Furthermore, a device mounting structure 8 is provided in the pipe body 6, through which the transmission line 13 connected to the PTC heating element 2 passes out of the housing 4. This makes the connection between the power supply and the heater simpler and more efficient, while avoiding the messy or heat conduction problems that may occur with the transmission line 13 in traditional heaters, ensuring the cleanliness and safety of the heater system.

[0050] Furthermore, the device mounting structure 8 includes: a clearance surface 10 and a mounting surface 11. Multiple clearance surfaces 10 and multiple mounting surfaces 11 are staggered, with each clearance surface 10 corresponding to a limiting groove 5. The bottom surface of each clearance surface 10 is coplanar with the bottom surface of the limiting groove 5. Mounting holes 12 are provided on the mounting surface 11. The clearance surface allows the transmission line 13 connected to the PTC heating element 2 to pass through, while the mounting surface 11 limits and mounts the device to be installed. Specifically, the required device is fixed to the mounting surface 11 using bolts, rivets, or other means. It should be noted that the type and quantity of the required devices depend on the design of the control circuit by those skilled in the art, and generally include temperature control elements 14, fuses, etc.
