[0054] The directions for innovation in existing technologies are as follows:

[0055] 1. Overall design of PTC liquid heater

[0056] The core of the PTC liquid heater lies in its carefully designed heater assembly 1, which not only includes multiple PTC heating elements 2, but also cleverly combines key components such as the semiconductor base 33, the liquid adding tube 5 (including the large through tube 51 and the shunt tube 52), the guide wire 7, the conductor piston 71 and the fixing part 6, together forming an efficient and stable heating system;

[0057] The semiconductor base 33 serves as the cornerstone of the heater, carrying the PTC heating element 2, and is connected to an external power source through the conductive rods 31 at both ends thereof, providing a continuous supply of electric energy for the entire heating process. The design of the liquid adding pipe 5 ensures that the liquid can smoothly enter the heater and be evenly distributed around the PTC heating element 2 through the shunt pipe 52, thereby achieving an efficient heating effect;

[0058] The introduction of the guide wire 7 and the conductor piston 71 has added a strong touch to the performance improvement of the heater. The guide wire 7 runs through the shunt tube 52 to guide the heat to be evenly distributed in the shunt tube 52, ensuring that all parts of the liquid can be fully heated. The conductor piston 71 is fixed to both ends of the PTC heating element 2 through the inspection piston 4, which not only realizes the sealed storage of the liquid, but also enhances the stability and safety of the overall structure.

[0059] The structural design of the six-hole disk 62 and the hexagonal column 61 of the fixing part 6 further reflects the refinement and ingenuity of the heater assembly 1. They ensure that the guide wire 7 and the conductor piston 71 can be evenly and effectively distributed on both sides of the PTC heating element 2, providing a strong guarantee for the stable operation of the heater.

[0060] 2. Detailed analysis of key components

[0061] (1) PTC heating element

[0062] The PTC heating element 2 is the core component of the heater, and its performance directly affects the quality of the heating effect. In the present invention, the PTC heating element 2 is installed at both ends of the semiconductor base 33 along its length direction, and is connected to the external power supply through the conductive rod 31, so as to obtain electrical energy and generate heat. This installation method not only ensures that the PTC heating element 2 can work stably and reliably, but also provides it with sufficient heat dissipation space, thereby extending its service life;

[0063] (2) Liquid filling pipe and diversion pipe

[0064] The design of the liquid adding pipe 5 is crucial to the heating process of the liquid. The liquid adding pipe 5 in the present invention comprises a large through pipe 51 and a shunt pipe 52. The liquid first enters the heater through the large through pipe 51, and then is evenly distributed around the PTC heating element 2 through the shunt pipe 52. This design not only optimizes the flow path of the liquid, but also ensures that the liquid can fully contact the heating element, thereby improving the heating efficiency.

[0065] (3) Guide wire and conductor piston

[0066] The guide wire 7 and the conductor piston 71 work together to achieve rapid and uniform heating of the liquid. The guide wire 7 runs through the shunt tube 52 to guide the heat to be evenly distributed in the shunt tube 52, while the conductor piston 71 is fixed to both ends of the PTC heating element 2 through the inspection piston 4 to evenly conduct the heat to the liquid in the shunt tube 52. This design not only ensures that all parts of the liquid can be fully heated, but also improves the uniformity and stability of the heating.

[0067] (4) Partition plates and fixings

[0068] The design of the partition plate 9 effectively isolates the influence of the external ambient temperature on the interior of the heater. They isolate the heat generated by the PTC heating element 2 from the external environment, maintaining the uniformity and efficiency of liquid heating. At the same time, the structural design of the six-hole plate 62 and the hexagonal column 61 of the fixing part 6 ensures that the guide wire 7 and the conductor piston 71 can be evenly and effectively distributed on both sides of the PTC heating element 2, providing strong support for the stable operation of the heater.

[0069] 3. In-depth analysis of the implementation examples

[0070] The first embodiment demonstrates the excellent performance of the PTC liquid heater in practical applications. Through the coordinated work of the carefully designed PTC heating element 2, the guide wire 7, and the conductor piston 71, the liquid is heated quickly and evenly. This design not only improves the heating efficiency, but also ensures the consistency of the heating quality. In practical applications, this heater is particularly suitable for laboratories or industrial production lines that require precise control of the liquid temperature.

[0071] The second embodiment further highlights the superiority of the design of the large through pipe 51 and the shunt pipe 52 in the heater assembly 1. They enable the liquid to smoothly enter and be evenly distributed around the PTC heating element 2 through the shunt pipe 52. This design optimizes the flow path of the liquid and ensures that the liquid can fully contact the heating element. At the same time, the longitudinal cross-sectional shape design of the PTC heating element 2 further optimizes the flow state of the liquid when it flows through, reduces the flow resistance, and improves the heating effect. This optimized liquid flow and heating structure is particularly suitable for liquid processing equipment that requires efficient and uniform heating.

[0072] Embodiment 3 emphasizes the important role of the maintenance piston 4 in the heater structure. The conductor piston 71 is fixed to the two ends of the PTC heating element 2 through the maintenance piston 4, thereby realizing the sealed storage of the liquid and enhancing the stability and safety of the overall structure. This design not only prevents the leakage of the liquid during the heating process, but also ensures the stability and safety of the current transmission. In practical applications, this enhanced structural stability and safety design improves the reliability and service life of the heater, and is particularly suitable for heating application scenarios that require long-term stable operation and have high safety requirements.

[0073] 4. Detailed explanation of working principle

[0074] In the working process, the PTC liquid heater is first connected to an external power source through the conductive rods 31 at both ends of the semiconductor base 33 to provide power to the PTC heating element 2. The liquid then enters the heater through the large through pipe 51 and is evenly distributed around the PTC heating element 2 through the shunt pipe 52. At this time, the guide wire 7 begins to guide the heat to be evenly distributed in the shunt pipe 52 to ensure that all parts of the liquid can be fully heated. At the same time, the partition plate 9 effectively isolates the influence of the external ambient temperature on the inside of the heater, avoiding heat loss and temperature fluctuations.

[0075] During the heating process, the firm fixing effect of the inspection piston 4 prevents the conductor piston 71 from moving or falling off due to changes in liquid pressure or temperature, which ensures the continuity and stability of current transmission, so that the heater can continuously and stably provide heat to the liquid;

[0076] As the heating process proceeds, the temperature of the liquid gradually rises until it reaches the preset heating temperature. At this time, the heater will automatically stop heating and keep the temperature of the liquid stable. When heating is needed again, just reconnect the external power supply;

[0077] In summary, PTC liquid heaters have demonstrated strong strength in various heating application scenarios with their unique design concept and excellent working performance. Whether it is precise temperature control in laboratories, efficient heating of industrial production lines, or constant temperature control systems for medical equipment, or liquid propellant heating devices in the aerospace field, PTC liquid heaters can provide reliable and stable heating solutions.
