Description

A thermal processor Technical Field

[0001] This utility model relates to the field of temperature control equipment technology, and in particular to a heat processor. Background Technology

[0002] With the continuous development of modern industrial technology and the demands of daily life, the need for precise temperature control in near-surface areas is increasing, in fields such as temperature control for wearable devices, temperature control for precision instruments, and temperature control for the transportation of biological products. Traditional temperature control systems often suffer from problems such as slow response speed, low temperature control accuracy, and limited functionality.

[0003] Currently, most common temperature control devices on the market use a single heating or cooling method, which is difficult to meet the dual needs of rapid heating and cooling in complex environments. Some systems with heating and cooling functions set up the heating and cooling components independently, resulting in complex system structure, large size, low heat exchange efficiency, and easy mixing of hot and cold media, which not only affects the temperature control effect but may also cause system failure.

[0004] Based on the above situation, we propose a thermal processor to solve the above problems. Summary of the Invention

[0005] This invention provides a thermal processor to solve the problems existing in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A heat processor includes a container for holding a heat-conducting medium. Inside the container, two semi-enclosed flow-guiding baffles are staggered vertically, dividing the container into a flow-guiding zone between the two baffles and a cold zone and a hot zone located on either side of the flow-guiding zone. The upper opening of the flow-guiding zone faces the cold zone, and the lower opening faces the hot zone. The cold zone and the hot zone are cooled and heated respectively by a thermoelectric cooler and a PTC ceramic heating element. The cold zone and the hot zone are connected by a circulation pipeline.

[0008] Preferably, the circulation pipeline includes a first circulation pipe connected to the hot zone, a second circulation pipe connected to the cold zone, and a capillary network connecting the first circulation pipe and the second circulation pipe. The first circulation pipe and the second circulation pipe are respectively provided with a heating loop circulation pump for constructing a heating medium circulation path and a cooling loop circulation pump for constructing a cooling medium circulation path.

[0009] Preferably, the first circulation pipe is equipped with a hot zone pressure-controlled flow regulator valve, which is connected to a first return pipe. The first return pipe is connected to the first circulation pipe via a manifold tee. The heating circuit circulation pump constructs a circulation path from the upper part of the hot zone through the capillary network, the cold zone, and the guide zone to the hot zone at a position outside the manifold tee of the hot zone pressure-controlled flow regulator valve's return pipe. The second circulation pipe is equipped with a cold zone pressure-controlled flow regulator valve, which is connected to a second return pipe. The second return pipe is connected to the second circulation pipe via a manifold tee. The refrigeration circuit circulation pump constructs a circulation path from the bottom of the cold zone through the capillary network, the hot zone, and the guide zone to the cold zone at a position after the manifold tee of the cold zone pressure-controlled flow regulator valve's return pipe.

[0010] Preferably, the flow guiding area is provided with an installation cavity, and the installation cavity is provided with a temperature sensor.

[0011] Preferably, the hot zone is provided with a PTC component mounting slot, and the PTC ceramic heating component is installed in the PTC component mounting slot by a spring clamping mounting structure.

[0012] Preferably, the circulation pipeline is also equipped with a liquid level sensor.

[0013] The beneficial effects of this utility model are as follows: by constructing a flow guiding zone through a flow guiding baffle, directional circulation and precise separation of hot and cold media are achieved, avoiding heat exchange efficiency loss caused by mixed flow and improving heat exchange efficiency. The thermoelectric cooler and the PTC ceramic heating component act on the cold and hot zones respectively. The heating circuit forms a cycle from the hot zone through the cold zone and the flow guiding zone back to the hot zone, while the cooling circuit forms a cycle from the cold zone through the hot zone and the flow guiding zone back to the cold zone. This symmetrical and orderly design of two independent cycles ensures that the medium fully exchanges heat in each zone, further improving heat transfer efficiency. Individual cooling and heating can be achieved as needed, meeting the temperature control requirements under different working conditions and improving the system's temperature control response speed and stability.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0019] Referring to Figures 1 and 2, a heat processor includes a container 1 for holding a heat-conducting medium. The container 1 can be a rectangular, flat metal container with good thermal conductivity. Inside the container 1, two semi-enclosed flow guide baffles 2 are staggered vertically. The flow guide baffles 2 divide the container 1 into a flow guide zone 11 between the two flow guide baffles 2 and a cold zone 12 and a hot zone 13 located on both sides of the flow guide zone 11. The upper opening of the flow guide zone 11 faces the cold zone 12, and the lower opening faces the hot zone 13. The cold zone 12 and the hot zone 13 are cooled and heated respectively by a thermoelectric cooler 121 and a PTC ceramic heating component 131. The cold zone 12 and the hot zone 13 are connected by a circulation pipeline. The flow guide zone 11 is provided with an installation cavity 8, and the installation cavity 8 is provided with a temperature sensor 81, which can measure the temperature of the heat-conducting medium in the flow guide zone 11 in real time, allowing the user or control system to accurately understand the current temperature status of the medium.

[0020] Specifically, cold zone 12 is cooled by the cold end of thermoelectric cooler 121. Thermoelectric cooler 121 is a cooling device based on the Peltier effect. When current passes through thermoelectric cooler 121, a temperature difference is generated at its two ends, and the temperature of the cold end decreases, thereby cooling the heat-conducting medium in cold zone 12. By precisely controlling the magnitude and direction of the current in thermoelectric cooler 121, the temperature of cold zone 12 can be accurately regulated. Hot zone 13 is heated by PTC ceramic heating element 131. PTC ceramic heating element 131 has advantages such as automatic temperature control, high thermal efficiency, and good safety. When temperature sensor 81 detects that the temperature is higher than the set value, thermoelectric cooler 121 starts and reduces power to maintain operation after the temperature drops to the set range; when the temperature is lower than the set value, PTC ceramic heating element 131 starts and reduces power to maintain operation after the temperature rises to the set range, thereby maintaining the temperature stability of hot zone 13. Cold zone 12 and hot zone 13 are connected by a circulation pipeline to form a closed-loop system.

[0021] Referring to Figure 1, the circulation system further includes a first circulation pipe 4 connected to the hot zone 13, a second circulation pipe 41 connected to the cold zone 12, and a capillary network 33 connecting the first circulation pipe 4 and the second circulation pipe 41. The first circulation pipe 4 and the second circulation pipe 41 are respectively equipped with a heating loop circulation pump 43 for constructing the circulation path of the heating medium and a cooling loop circulation pump 44 for constructing the circulation path of the cooling medium, to provide a certain pressure and drive the heat transfer medium to circulate, enabling the entire system to operate continuously and stably. In actual use, both ends of the capillary network 33 can be connected to... The quick-connect structure, such as the quick connector, can be quickly connected to the first circulation pipe 4 and the second circulation pipe 41. The capillary network 33 can be set inside the product according to the usage requirements, such as sewn inside the clothing or installed inside the sleeping bag. The cooling medium in the cold zone 12 passes through the capillary network 33 and then returns to the container 1. The capillary network 33 cools down the clothing or sleeping bag. Conversely, when heating is required, the PTC ceramic heating component 131 in the hot zone 13 heats the clothing or sleeping bag and then returns to the cold zone 12 after passing through the capillary network 33. At this time, the capillary network 33 can heat up the clothing or sleeping bag.

[0022] Referring to Figure 1, further, a hot zone pressure-controlled flow regulator 5 is provided on the first circulation pipe 4. The hot zone pressure-controlled flow regulator 5 is connected to a first return pipe 51. The first return pipe 51 is connected to the first circulation pipe 4 through a manifold tee. The heating circuit circulation pump 43 constructs a counterclockwise circulation path from the upper part of the hot zone 13 through the capillary network 33, the cold zone 12, and the guide zone 11 to the bottom of the hot zone 13 at the position outside the manifold tee of the return pipe of the hot zone pressure-controlled flow regulator 5. A cold zone pressure-controlled flow regulator 6 is provided on the second circulation pipe 41. The cold zone pressure-controlled flow regulator 6 is connected to a second return pipe 61. The second return pipe 61 is connected to the second circulation pipe 41 through a manifold tee. The cooling circuit circulation pump 44 constructs a circulation path from the bottom of the cold zone 12 through the capillary network 33, the hot zone 13, and the guide zone 11 to the upper part of the cold zone 12 at the position after the manifold tee of the return pipe of the cold zone pressure-controlled flow regulator 6.

[0023] Specifically, in the circulation pipeline of hot zone 13, a hot zone pressure-controlled flow regulator 5 is installed on the first circulation pipe 4. Its main function is to precisely control and stabilize the pressure in the circulation pipeline of hot zone 13. The hot zone pressure-controlled flow regulator 5 is connected to the first return pipe 51, which is connected to the first circulation pipe 4 through a manifold tee. When the pressure in the circulation pipeline of hot zone 13 exceeds the preset range, such as when the capillary network 33 is bent in clothing products, the circulation effect of the liquid heat transfer medium is poor, and the hot zone pressure-controlled flow regulator 5 will open the corresponding regulating mechanism. The system is designed to allow some of the heat transfer medium to return to the first circulation pipe 4 through the first return pipe 51 to ensure stable pressure within the pipeline and prevent damage to the entire system due to abnormal pressure. The heating loop circulation pump 43 is installed outside the hot zone pressure control valve 5, the return pipe, and the manifold tee. Its function is to drive the heat transfer medium to circulate. Specifically, a circulation path can be constructed from the upper part of the hot zone 13 through the circulation pipeline, the cold zone 12, and the guide zone 11 to the hot zone 13. During this circulation process, the heat transfer medium is heated to a higher temperature by the PTC ceramic heating component in the upper part of the hot zone 13 and has high energy. Driven by the heating loop circulation pump 43, the heat transfer medium flows through the first circulation pipe 4 and the capillary network 33 to the cold zone 12 and the hot zone 13 and then circulates again.

[0024] In the circulation pipeline of cold zone 12, a cold zone pressure-controlled flow regulator 6 is installed on the second circulation pipe 41. Similar to the hot zone pressure-controlled flow regulator 5, the function of the cold zone pressure-controlled flow regulator 6 is to control and stabilize the pressure in the circulation pipeline of cold zone 12. When the pressure in the circulation pipeline of cold zone 12 fluctuates, the cold zone pressure-controlled flow regulator 6 will respond in time to ensure that the pressure in the pipeline is stable. The cold zone pressure-controlled flow regulator 6 is connected to the second return pipe 61, which is connected to the second circulation pipe 41 through a manifold tee. When the pressure in the circulation pipeline of cold zone 12 needs to be adjusted, some heat transfer medium can flow back to the second circulation pipe 41 through the second return pipe 61 to achieve pressure balance. The refrigeration circuit circulation pump 44 is installed after the cold zone pressure-controlled flow regulator 6, the return pipe, and the manifold tee. It constructs a circulation path from the bottom of cold zone 12 through the circulation pipeline, hot zone 13, guide zone 11 to the upper part of cold zone 12.

[0025] When the circulation pipeline or part of the capillary network 33 is squeezed and the flow is interrupted by external force, a local circulation path will be formed between the pump and the pressure control valve through the action of the hot zone pressure control valve 5 or the cold zone pressure control valve 6, which will reduce the system pressure and prevent excessive pressure from causing overload and burnout.

[0026] Furthermore, a liquid level sensor 14 is installed on the circulation pipeline. When the liquid level sensor 14 detects a flow interruption, it can promptly issue an alarm to remind personnel or cut off the power supply to the associated actuator through a controller or warning device that is electrically connected to it.

[0027] Referring to Figure 2, furthermore, the hot zone 13 is provided with a PTC component mounting slot 9. The PTC ceramic heating component 131 is installed in the PTC component mounting slot 9 through a spring-clamped mounting structure, which enhances the firmness and reliability of the installation. Moreover, the base surface can be filled with alumina ceramic microspheres as a thermally conductive medium. Alumina ceramic microspheres have good thermal conductivity, which can effectively transfer the heat generated by the PTC ceramic heating component to the surrounding environment, improve the heat transfer efficiency, reduce the accumulation of heat in the PTC component mounting slot, and make the temperature of the hot zone 13 cavity more uniform, thereby improving the performance and stability of the entire heating system.
