Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal management technology, specifically a distributed system. Background Technology
[0002] Thermal oil is a commonly used heat transfer medium in thermal management systems. It features uniform heating, accurate temperature control, low volatility, and good heat transfer performance. It is widely used in production processes such as chemical, artificial board, circuit board, printing and dyeing, textile, plastic, rubber, resin, coating, road construction, papermaking, and grain and oil food processing.
[0003] Electric heating heat transfer tanks use heat transfer oil as the heat carrier. An electric heating element is inserted into the tank containing the oil, heating the oil via an electric heater and circulating it through an oil pump for heat exchange. However, existing electric heaters are directly inserted into the tank, and their heating area cannot cover the entire tank, leading to uneven heating of the oil. Currently, to improve energy efficiency, the most common method used in the market is to modify the shape or structure of the electric heater, such as designing it as a spiral to increase its contact surface with the oil.

[0038] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.
[0039] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0042] In existing technologies, the outlet of an electrically heated heat transfer tank is typically located at the bottom, while the inlet is located at the top. Based on the principles of fluid flow, the heat transfer oil within the tank flows at a higher velocity closer to the outlet, and flows slowly or even stagnates further away. This means the flow path of the heat transfer oil varies across different areas, and without stirring, only a portion of the oil typically participates in heat exchange. Furthermore, the conventionally designed heating rods are limited in size and cannot cover the cross-section of the heat transfer tank, resulting in uneven heating within the tank. The combination of these two drawbacks means that the heat transfer oil further from the outlet is continuously heated, while the oil closer to the outlet remains below the preset temperature, thus affecting the heat exchange efficiency with the heat-using equipment and reducing production efficiency.
[0043] To address the aforementioned problems, this invention provides a dispersion system that forms a unidirectional flow oil passage within the heat transfer tank 1, ensuring that the heat transfer oil has the same flow path, guaranteeing that the heat transfer oil is heated evenly and maintaining a stable thermal cycle in the circulation path, thereby improving the heat exchange effect on the dispersion vessel 2.
[0044] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0045] Example 1
[0046] Figure 1 This is a schematic diagram of the overall structure of the distributed system shown in an embodiment of the present invention.
[0047] like Figure 1 As shown, the present invention provides a dispersion system in embodiment 1, including a heat-conducting tank 1 with a vent 10. The heat-conducting tank 1 is provided with a plurality of spaced partitions 11, and the partitions 11 form an oil passage.
[0048] The dispersion vessel 2 has a heat-conducting pipe 20 surrounding its outer surface, and the heat-conducting pipe 20 is connected to the oil passage to form a circulation path;
[0049] Heating element 3 is disposed on the oil passage;
[0050] Oil pump 4 is located in the circulation path and is used to provide the circulation power for the heat transfer oil.
[0051] The heat transfer tank 1 is equipped with several spaced baffles 11, forming a sandwich layer between them. This sandwich layer, together with the inner wall of the heat transfer tank 1, forms a chamber. These chambers within the heat transfer tank 1 are interconnected, forming an oil passage. The heating element 3 is located within this oil passage and can be placed in any of the chambers. Under the action of the oil pump 4, the heat transfer oil flows through the oil passage, passing over the heating element 3 to achieve heating. The heated oil then flows through the heat transfer tank 1 to transfer heat to the wall of the dispersion vessel 2, thereby heating the material within the dispersion vessel 2. This invention, by setting a unidirectional flow oil passage, ensures that the heat transfer oil has the same flow path and velocity within the heat transfer tank 1, avoiding the undesirable situation of stagnation and accumulation of the heat transfer oil within the heat transfer tank 1.
[0052] In this embodiment, the partition 11 can be a flat plate, an arc-shaped plate, or a corrugated plate. The size of the partition 11 is the same as the inner circumferential diameter of the heat transfer tank 1, and the partition 11 has a notch for connecting the various chambers. The notches between the partitions 11 are mirror images of each other, thereby forming an S-shaped oil passage in the heat transfer tank 1.
[0053] In practical applications, during the heating process, the heat transfer oil inevitably produces waste oil vapor or volatile organic compounds generated by the cracking of the heat transfer oil. In order to maintain the pressure balance between the heat transfer tank 1 and the atmospheric pressure, a corresponding vent 10 is set on the heat transfer tank 1 to discharge the waste in the heat transfer tank 1 in a timely manner and ensure the safety of production operations.
[0054] It should be noted that those skilled in the art can determine the distance between the partitions 11 by the processing capacity of the dispersion vessel 2, the delivery capacity of the oil pump 4, and the efficiency of the heating element 3; no single limitation is imposed here.
[0055] The dispersion system provided by this utility model solves the problem of different flow paths of heat transfer oil. By setting baffle 11 to construct a unidirectional S-shaped oil passage, the heat transfer oil in the heat transfer tank 1 can maintain flow and achieve heating in the process of flow, thus realizing balanced heating and effective heat circulation of the heat transfer oil.
[0056] Based on the above specific embodiments, those skilled in the art can set a number of baffles perpendicular to the baffle 11 on the baffle 11, thereby further forming a unidirectional flow channel in the above-mentioned chamber and improving the fluidity of the heat transfer oil in each chamber.
[0057] Furthermore, the baffle 11 of the aforementioned dispersion system is inclinedly disposed within the heat transfer tank 1. The inclined placement of the baffle 11 within the heat transfer tank 1 can prevent the heat transfer oil from stagnating within the baffle 11.
[0058] Furthermore, the angle between the partition 11 of the above-mentioned dispersion system and the horizontal plane is 1°~3°.
[0059] Example 2
[0060] like Figure 2 As shown, the present invention provides a dispersion system in embodiment 1, including a heat-conducting tank 1 with a vent 10. The heat-conducting tank 1 is provided with a plurality of spaced partitions 11, and the partitions 11 form an oil passage.
[0061] The dispersion vessel 2 has a heat-conducting pipe 20 surrounding its outer surface, and the heat-conducting pipe 20 is connected to the oil passage to form a circulation path;
[0062] Heating element 3 is disposed on the oil passage;
[0063] Oil pump 4 is located in the circulation path and is used to provide the circulation power for the heat transfer oil.
[0064] Furthermore, the outlet end 12 of the oil passage of the aforementioned dispersion system is connected to the inlet end of the heat-conducting pipe 20, and the inlet end 13 of the oil passage is connected to the outlet end of the heat-conducting pipe 20. The oil pump 4 is disposed between the outlet end 12 of the oil passage and the inlet end of the heat-conducting pipe 20. The outlet end 12 of the oil passage is also provided with a regulating valve 5, which is used to control the flow rate of the oil passage. Specifically, the outlet end 12 of the oil passage is located at the bottom, and the inlet end 13 of the oil passage is located at the top. With this arrangement, it is convenient for the oil pump 4 to draw heat-conducting oil from the outlet end 12.
[0065] Furthermore, the heating element 3 of the above-mentioned distributed system includes several heating rods and a control device arranged side by side, with gaps between adjacent heating rods, the heating rods being connected to the control device, and the regulating valve 5 being electrically connected to the control device;
[0066] A heating interface is provided on the outer side of the heat-conducting tank 1, and the heating rod is installed in the heat-conducting tank 1 through the heating interface. The heating rod is located between adjacent partitions 11.
[0067] The bottom of the heat transfer tank 1 is also provided with a drain port. There are gaps between the several heating rods arranged side by side, so that the heat transfer oil can be immersed in and cover the heating rods, and prevent the heating rods from dry burning.
[0068] In practical applications, the heat transfer oil comes into direct contact with the heating rod. Under local high temperature conditions, the heat transfer oil will inevitably carbonize and deteriorate, and insoluble substances will be generated. Therefore, after a period of use, the insoluble precipitates of the heat transfer tank 1 can be discharged through the drain port.
[0069] Furthermore, in order to accurately control the temperature of the heat transfer oil, based on the above specific implementation, the dispersion system also includes a temperature measuring tube 6, two first temperature sensors (not shown), and a second temperature sensor (not shown).
[0070] The top of the heat transfer tank 1 is provided with an installation hole for inserting the temperature measuring tube 6, and each of the partitions 11 is provided with a through hole for inserting the temperature measuring tube 6. The end of the temperature measuring tube 6 is close to the outlet end 12 of the oil passage.
[0071] The outer surface of the temperature measuring tube 6 is provided with a first temperature measuring port 61 and a second temperature measuring port 62. The first temperature measuring port 61 is close to the inlet end 13 of the oil passage, and the second temperature measuring port 62 is close to the outlet end 12 of the oil passage.
[0072] The detection ends of the two first temperature sensors are exposed outside the temperature measuring tube 6 through the first temperature measuring port 61 and the second temperature measuring port 62, respectively;
[0073] The second temperature sensor is installed inside the dispersion vessel 2 to monitor the material temperature in the dispersion vessel 2;
[0074] Both the first temperature sensor and the second temperature sensor are connected to the control device, which is used to adjust the output power of the heating rod or adjust the opening of the regulating valve 5 based on the temperature information from the two first temperature sensors and the temperature information from the second temperature sensor.
[0075] Two first temperature sensors monitor the temperatures at the inlet 13 and outlet 12 of the heat transfer tank 1, respectively, while a second temperature sensor monitors the material temperature in the dispersion vessel 2. During operation, preset temperatures for the current production are input into the control device, such as the highest and lowest temperatures of the material, the preset output power of the electric heating rod, the preset temperature at the inlet 13 of the heat transfer tube 20, and the preset temperature at the outlet 12 of the heat transfer tank 1. After the control device obtains the corresponding real-time temperature information through the first and second temperature sensors, it compares it with the preset values. If the real-time value is within the corresponding range, the operator is reminded to perform appropriate operations or manually control the current output of the electric heating rod or the flow rate of the regulating valve 5. If the real-time value exceeds the preset range, an alarm is issued to inform the operator to troubleshoot the problem.
[0076] Furthermore, the aforementioned distributed system also includes a temperature data acquisition device (not shown); the temperature data acquisition device is connected to the first temperature sensor and the second temperature sensor, and is connected to the control device; the temperature data acquisition device is used to acquire the temperature information of the two first temperature sensors and the temperature information of the second temperature sensor.
[0077] Both the first temperature sensor and the second temperature sensor are K-type thermocouples.
[0078] Specifically, the K-type thermocouple features high accuracy, capable of monitoring temperatures down to 0.01℃, with a monitoring range of -20℃ to 400℃, and can be used long-term in heat transfer oil. After acquiring the temperature information from the K-type thermocouple, the temperature data acquisition instrument can automatically plot temperature curves, facilitating operators to compare temperature information and refine the design of temperature and flow parameters.
