Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following description, with reference to the accompanying drawings, describes an embodiment of the present invention: a preheater with controllable outlet temperature.

[0021] like Figures 1-4 As shown, a preheater with controllable outlet temperature according to an embodiment of the present invention may include: a preheater body 1, a temperature control mechanism 2, a control component 3, a temperature regulating valve 4, and a heating rod 5, wherein.

[0022] The temperature control mechanism 2 is located inside the preheater body 1. The temperature control mechanism 2 includes an output component 21, a water supply pipe 22, a water tank 23, and a circulating water pipe 24. The output component 21 is fixed on one side of the preheater body 1. The water supply pipe 22 is connected to the input end of the output component 21. The circulating water pipe 24 is connected to the output end of the output component 21. The water tank 23 is connected to one side of the water supply pipe 22.

[0023] It should be noted that the output component 21 is a water pump, and the cooling water is circulated in the circulating water pipe 24.

[0024] Specifically, the internal structure of the preheater body 1 is designed as a multi-layer structure, including at least two layers of heating chambers. Each heating chamber is equipped with a heating rod 5, which is connected to the control component 3 via wires. The control component 3 is responsible for receiving signals from the temperature sensor and automatically adjusting the heating power of the heating rod 5 according to the preset temperature range to achieve precise control of the outlet temperature. Thermostatic valve 4 is set at the outlet of the preheater body 1 to regulate the amount of water flowing through the heating chamber, thereby controlling the heating efficiency and the outlet temperature. During operation, cooling water enters the water tank 23 through the water supply pipe 22, and then enters the preheater body 1 through the output component 21. The cooling water returns to the water tank 23 through the circulating water pipe 24, forming a circulation system. By adjusting the opening of the thermostatic valve 4, the amount of water flowing through the heating chamber can be controlled, thereby adjusting the heating efficiency and the outlet temperature. The control component 3 automatically adjusts the heating power of the heating rod 5 according to the real-time temperature data fed back by the temperature sensor to ensure that the outlet temperature is kept within the set range.

[0025] In one embodiment of this utility model, such as Figure 1 As shown, the preheater body 1 includes a preheating pipe 11, a preheater inlet 12, and a preheater outlet 13.

[0026] A preheater inlet 12 is provided on one side of the preheating pipe 11, and a preheater outlet 13 is provided on the other side of the preheating pipe 11.

[0027] In one embodiment of this utility model, such as Figure 2 As shown, the control component 3 includes a controller 31, an electrical box 32, a main board 33, and a sensor 34.

[0028] The controller 31 is located on one side of the preheating pipe 11, the electrical box 32 is located on one side of the controller 31, the main board 33 is located inside the controller 31, and the sensor 34 is located on the preheater outlet 13.

[0029] Specifically, sensor 34 is used to monitor the temperature of preheater outlet 13 in real time and transmit the temperature data to control component 3. Based on the data provided by sensor 34, control component 3 controls the amount of water flowing through the heating chamber by adjusting the opening of thermostatic valve 4, thereby adjusting the heating efficiency and outlet temperature. The adjustment of thermostatic valve 4 is automatic to adapt to different working conditions and user needs.

[0030] In one embodiment of this utility model, such as Figure 1 As shown, the thermostatic valve 4 is located on one side of the circulating water pipe 24.

[0031] Understandably, referencing the automotive cooling system, the thermostat valve 4 is electronically controlled. It receives temperature signals from the sensor 34 via the controller 31 and automatically adjusts the opening of the thermostat valve 4 according to a preset temperature control algorithm.

[0032] In one embodiment of this utility model, such as Figure 4 As shown, a heating rod 5 is installed inside the preheater outlet 13.

[0033] Understandably, the power of the heating rod 5 can be adjusted according to the temperature of the preheater outlet 13. When the temperature detected by the sensor 34 is lower than the set temperature threshold, the controller 31 will instruct the heating rod 5 to increase the heating power to improve heating efficiency and outlet temperature. Conversely, when the detected temperature is higher than the threshold, the controller 31 will instruct the heating rod 5 to reduce the heating power to achieve the most suitable outlet temperature.

[0034] In summary, this utility model provides a preheater with controllable outlet temperature. Through precise control of the temperature control mechanism, it can achieve fine adjustment of the preheating temperature to meet the needs of different working conditions. The heating rod configuration results in higher preheating efficiency and faster heating speed, enabling rapid attainment of the set working temperature. The intelligent design of the control components enables automatic control and remote monitoring, improving the convenience of operation and the reliability of the system. The use of a thermostatic valve can effectively regulate the temperature of the circulating water, ensuring that the preheater operates at the optimal temperature and extending the service life of the equipment. The preheater of this utility model is designed with energy conservation and environmental protection in mind, reducing energy consumption and lowering operating costs by optimizing heat exchange efficiency.
