Description

Technical Field

[0001] This invention relates to the field of thermal management technology, and more particularly to a compact single-channel thermal management system. Background Technology

[0002] Thermal management technology plays an indispensable and crucial role in numerous scenarios, including industrial production, scientific experiments, and daily life. In the field of metal cutting, the high-speed cutting of tools and workpieces generates a large amount of heat. If the cutting surface is not effectively cooled in time, it will not only lead to accelerated tool wear and a significantly shortened service life, but also affect the machining accuracy and surface quality of the workpiece, and may even cause the workpiece to be scrapped due to thermal deformation. In daily life, electronic products such as mobile phones will also experience high temperatures and performance degradation during continuous operation in hot weather. In the processing of some special materials, such as the preparation of some composite materials and high-temperature alloys, alternating hot and cold treatments are often required. By precisely controlling temperature changes, the microstructure of the material can be regulated to obtain the required mechanical and physicochemical properties. If the excess heat generated during processing or the required low-temperature environment cannot be properly controlled in time, it will not only cause a large amount of energy waste, but may also lead to equipment damage and material performance degradation due to excessive local energy concentration or thermal shock, resulting in production safety accidents. These temperature-related problems directly or indirectly restrict the stable operation of equipment, and also highlight the importance and urgent need for efficient thermal management systems.

[0003] In the general design of traditional independent temperature control systems for heating and cooling, the heating and cooling channels are usually set up with separate flow paths. For example, most publicly available temperature control devices for heating and cooling circulation generally adopt a dual-pipe structure, which is responsible for transporting the heat medium and the cold medium respectively. The switching between cooling and heating functions is simply achieved by switching the on and off of different pipes. At the same time, some independent temperature control systems for heating and cooling have also equipped the heating circuit and the cooling circuit with their own independent pumps, valves and heat exchange components. Although such systems can clearly distinguish between heating and cooling functions and ensure the stability of temperature control to a certain extent, they also have many defects that cannot be ignored:

[0004] On the one hand, the multi-channel design significantly increases the complexity and production cost of the system. Independent flow channels require additional pipes, connectors, seals and other components. At the same time, in order to ensure the independent operation of each channel, multiple sets of control valves and monitoring equipment are required. This makes the overall size of the system larger and increases the difficulty of installation and maintenance. It is especially unsuitable for small equipment and precision instruments with high space requirements.

[0005] On the other hand, in practical use, independent temperature control systems for heating and cooling require independent control and drive of the heating and cooling channels. When switching operating modes is needed, the current channel must be shut down first, and then the power system and temperature control components of the other channel must be started. This process is not only cumbersome but also has a significant response delay, resulting in low cooling and heating efficiency. In addition, the independent flow channel design is more prone to energy loss, and the heat exchange between channels is difficult to utilize effectively, further reducing the system's energy efficiency.

[0006] Therefore, to solve the above problems, this invention proposes a compact single-channel thermal management system that can reduce the number of channels, lower manufacturing costs, and flexibly switch between cooling and heating functions. Summary of the Invention

[0007] To address the problems existing in the prior art, the present invention provides a compact single-channel thermal management system.

[0008] According to one objective of the present invention, the present invention provides a compact single-channel thermal management system, including a temperature control subsystem, a one-way valve, a delivery channel, a power system, and an action channel;

[0009] The temperature control subsystem includes two parts: refrigeration and heating. Each part is provided with an input port and an output port. The input port and the output port are respectively connected to the working channel through a common conveying channel. The output port and the input port of the same part can be connected through the conveying channel to form a circulation loop. The power system is provided on the conveying channel. The power system is configured to provide forward or reverse circulation power to the medium in the circulation loop.

[0010] An independent one-way valve is provided between the temperature control subsystem and the conveying channel. The one-way valve is configured to control the opening of the circulation loop corresponding to the refrigeration or heating part of the temperature control subsystem.

[0011] Preferably, the power system employs a peristaltic pump, which synchronously drives the first channel and the second channel.

[0012] When in use, the power unit in the middle provides power. Taking a peristaltic pump as an example, the one-way valve of the heating section is open and the one-way valve of the cooling section is closed. When the peristaltic pump rotates clockwise, it drives the heat source to pump fluid out from the one-way valve of the heating section. The fluid flows from the one-way valve of the heating section into the heat source storage system through the action section. This stage realizes the heating function. At the same time, since the one-way valve of the cooling section is closed, there is no liquid exchange with the cold source.

[0013] The power system needs to provide power in both clockwise and counterclockwise directions in order to successfully separate the working channels of the hot and cold sources.

[0014] Preferably, the connection points of the second branch channel and the second channel, as well as the connection points of the first branch channel and the first channel, intersect to form a T-shaped or Y-shaped three-way structure. A special connection method is required between the transport channel and a certain source of cold or heat; using a Y-shaped or T-shaped connection method allows the flow channels of the cold source and the heat source to merge into the same transport channel.

[0015] Preferably, the temperature control subsystem is equipped with a temperature sensor, which is electrically connected to the temperature control subsystem. The temperature sensor is configured to detect fluid temperature data, display and transmit real-time data to the temperature control subsystem.

[0016] The temperature control subsystem employs semiconductor thermal conductivity and includes a container. A temperature sensor is mounted on the outer surface of the container. The temperature sensor and a processor are communicatively connected. The processor is configured to receive real-time data from the temperature sensor, perform temperature limit comparisons, and cut off power when the temperature exceeds the limit and reconnect the circuit when the temperature falls below the limit. The use of semiconductor thermal conductivity in the temperature control subsystem maximizes temperature control. Additionally, the device has a separate channel connected to the temperature sensor, providing access to the cold and heat sources under temperature limit control. Real-time temperature detection of the container (e.g., water tank, cup, battery container exterior) is performed using a high-precision sensor. After transmitting the real-time data to the processor, temperature limit comparisons are performed, cutting off power when the temperature exceeds the limit and reconnecting the circuit when the temperature falls below the limit. This design further improves operational efficiency.

[0017] Preferably, the action channel is a single soft conduit expulsion site that can meet a wide range of temperature limits;

[0018] The action channel can adopt a spiral or cross structure. A single tube body section can be used as the action channel, or two tubes can be connected. It is necessary to ensure that the strength of this stage is sufficient and that the temperature resistance range of the action channel can withstand the fluid temperature of the cold and heat source. The channel will not harden due to low temperature or melt due to high temperature. In addition, the action channel needs to be in contact with the action site, so the channel is preferably a flexible tube to maximize the contact area.

[0019] Preferably, the conveying channel is divided into a first channel and a second channel arranged in parallel. The first end of the first channel is connected to the output port of the heating part, the first end of the second channel is connected to the input port of the heating part, and the second ends of the first channel and the second channel are respectively connected to the working channel.

[0020] The first channel extends into a first branch channel near the location of the cooling section, which connects to the output port of the cooling section; the second channel extends into a second branch channel near the location of the cooling section, which connects to the input port of the cooling section.

[0021] Preferably, the one-way valve is divided into a first valve, a second valve, a third valve, and a fourth valve. The first valve is located at the output port of the heating section, the second valve is located at the input port of the heating section, the third valve is located at the output port of the cooling section, and the fourth valve is located at the input port of the cooling section.

[0022] Preferably, the function channel completes the hot and cold alternation through the power system alone. The power system is connected to the neck of the function channel. When the system is working, the device can realize the functions of heating and cooling forward and reverse fluid transport.

[0023] When the system is heating, the power unit provides power in the forward direction, the first and second valves open, and the third and fourth valves close, thus closing the one-way valve of the refrigeration module and opening the one-way valve of the heating module. The operating channel only provides power to the heating module. Conversely, when the system is cooling, the power unit provides power in the reverse direction, the first and second valves close, and the third and fourth valves open, thus closing the one-way valve of the heating module and opening the one-way valve of the refrigeration module. The operating channel only provides power to the refrigeration module.

[0024] The working channel neck is connected to a power system, which uses a pump device. The device can realize forward and reverse transportation functions. When the pump rotates clockwise, the system performs a heating / cooling function, and when it rotates counterclockwise, it corresponds to another function.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] This compact single-channel thermal management system requires no other mechanical structures; it only needs a pump to achieve alternating heating and cooling, resulting in a simple structure.

[0027] The temperature control subsystem provides traditional cold and heat source power. On this basis, it adopts an innovative positive and negative one-way valve design, which allows the cold and heat sources to share a single delivery channel, reducing resource waste and production costs. The circulation loop, driven by the power system, autonomously defines its forward and reverse functions. For example, when the circulation loop of the heating part of the temperature control subsystem is open, the circulation loop of the cooling part of the temperature control subsystem is closed. The power system drives the medium in the circulation loop in the forward direction, and vice versa.

[0028] Compared to traditional independent temperature control systems for heating and cooling, which require separate flow channels for heating and cooling, this design improves the system's cooling and heating efficiency and eliminates the need for separate control and separate drive for heating and cooling.

[0029] Meanwhile, the system achieves heating and cooling functions solely through a power unit without relying on external mechanical structures, making it simpler and more convenient than traditional independent temperature control systems for both hot and cold.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0038] The following description is intended to provide a detailed account of the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0039] Please see Figure 1 and 2 The present invention provides a technical solution: a compact single-channel thermal management system, which includes: a temperature control subsystem 100, a one-way valve 500, a conveying channel 200, a power system 400 and an action channel 300;

[0040] The temperature control subsystem 100 includes two parts: refrigeration and heating. Each part is provided with an input port a and an output port b. The input port a and the output port b are respectively connected to the action channel 300 through the conveying channel 200. The refrigeration and heating parts share the same conveying channel 200. The output port b and the input port a of the same part can be connected through the conveying channel 200 to form a loop.

[0041] The power system 400 is disposed in the conveying channel 200, and the power system 400 is configured to provide forward or reverse circulation power to the medium in the circulation loop;

[0042] An independent one-way valve 500 is provided between the refrigeration section 102 of the temperature control subsystem and the conveying channel 200, and between the heating section 101 of the temperature control subsystem and the conveying channel 200. The one-way valve 500 is configured to control the opening of the corresponding circulation loop of the refrigeration section 102 or the heating section 101 of the temperature control subsystem to realize single-path circulation.

[0043] This compact single-channel thermal management system can be used to solve thermal management problems in daily life and experimental production scenarios. It adopts innovative compact single-channel technology, which can efficiently and easily realize the output and input of cold and heat sources. The opening and closing of the 500 one-way valve can realize single circulation. The use of single channel effectively reduces energy loss and improves the thermal efficiency of the system. At the same time, the system also takes into account heating and cooling functions. The flexible change of working channel further increases the working range, and it can realize functions from scientific research thermal management to equipment cooling.

[0044] This compact single-channel thermal management system uses a temperature control subsystem 100 that provides traditional heat and cold source power. Based on this, it adopts an innovative design of forward and reverse one-way valves 500, which allows the heat and cold sources to share a single transport channel 200, reducing resource waste and production costs. The circulation loop, driven by the power system 400, autonomously defines forward and reverse functions. For example, when the circulation loop of the heating section 101 of the temperature control subsystem 100 is open, the circulation loop of the cooling section 102 of the temperature control subsystem 100 is closed, and the power system 400 drives the medium in the circulation loop in the forward direction, and vice versa.

[0045] Compared to traditional independent temperature control systems for heating and cooling, which require separate flow channels for heating and cooling, this design improves the system's cooling and heating efficiency and eliminates the need for separate control and drive for heating and cooling.

[0046] Regarding the specific construction of the conveyor channel 200, in this embodiment, see [link to documentation]. Figure 3 and 4The heating part 101 and the cooling part 102 of the temperature control subsystem are arranged at intervals along the length of the conveying channel 200. The conveying channel 200 is divided into a first channel 201 and a second channel 202 arranged in parallel. The first end of the first channel 201 is connected to the output port b of the heating part 101, and the first end of the second channel 202 is connected to the input port a of the heating part 101. The second ends of the first channel 201 and the second channel 202 are respectively connected to the action channel 300.

[0047] The first channel 201 extends into a first branch channel 2011 near the refrigeration section 102, connecting to the output port b of the refrigeration section 102. The second channel 202 extends into a second branch channel 2021 near the refrigeration section 102, connecting to the input port a of the refrigeration section 102. The connection points of the second branch channel 2021 and the second channel 202, as well as the connection points of the first branch channel 2011 and the first channel 201, intersect to form a T-shaped or Y-shaped three-way structure. The section of the conveying channel 200 connected to the temperature control subsystem 100 adopts a T-shaped or Y-shaped channel 300 for refrigeration and heating fluid action, that is, the flow channels of the cold source and the flow channels of the heat source are merged into the same conveying channel 200.

[0048] In this embodiment, the power system 400 uses a peristaltic pump, which synchronously drives the first channel 201 and the second channel 202. When the system is working, the peristaltic pump provides power in both clockwise and counterclockwise directions of rotation. The one-way valve 500 forms a switch to control the inlet and outlet of the cold and heat source, successfully isolating the working channel of the cold and heat source.

[0049] The action channel 300 employs a single flexible conduit for the expulsion section, capable of withstanding significant pressure while meeting temperature limits of 5℃-80℃. Preferably, the action channel 300 can adopt a spiral or cross-shaped structure. See [reference needed]. Figure 1 and 2 The illustrated embodiments, and Figure 6 and 7 The illustrated embodiments demonstrate two different structures for the function channel 300.

[0050] Furthermore, the temperature control subsystem 100 is equipped with a temperature sensor, which is electrically connected to the temperature control subsystem 100 to detect fluid temperature data, display and transmit real-time data to the temperature control subsystem 100, thereby achieving temperature control.

[0051] In this embodiment, the temperature control subsystem 100 uses semiconductor thermal conductivity to maximize temperature control. In addition, the device has a separate channel to connect to a high-precision temperature sensor, which detects the temperature of the container's exterior in real time. Optionally, the container can be a water tank, a water cup, or a battery container. After transmitting the real-time data to the processor, a temperature limit comparison is performed. If the temperature exceeds the limit, the power is cut off; if the temperature is below the limit, the circuit is reconnected, thereby controlling the energy supply of the external motor to the heating and cooling system.

[0052] Regarding the specific structure of the one-way valve 500, the one-way valve 500 is connected between the temperature control subsystem 100 and the delivery channel 200. The one-way valve 500 was designed from a flexible conduit, taking into account both the material properties required for the flexible conduit and the valve requirements. When the power system 400 operates, the pressure difference drives the fluid from the source (temperature control subsystem 100) into the delivery channel 200. Simultaneously, the pressure difference causes the one-way valve 500 to open and close. In this embodiment, the one-way valve 500 is divided into a first valve 501, a second valve 502, a third valve 503, and a fourth valve 504. The first valve... Door 501 is located at the output port b of the heating section 101, the second valve 502 is located at the input port a of the heating section 101, the third valve 503 is located at the output port b of the cooling section 102, and the fourth valve 504 is located at the input port a of the cooling section 102. In use, the opening and closing of different ports are controlled by different valves, and the power system 400 operates. When the system is heating, the first valve 501 and the second valve 502 are open, and the third valve 503 and the fourth valve 504 are closed. When the system is cooling, the first valve 501 and the second valve 502 are closed, and the third valve 503 and the fourth valve 504 are open.

[0053] In another scalable embodiment, see Figure 7 The thermal management system can adopt a modular array structure to achieve precise temperature control over a larger area or multiple independent regions;

[0054] Specifically, the functional unit integrated with the temperature control subsystem 100, the one-way valve 500, and the control system mounted thereon is defined as a temperature control module. This temperature control module can work in conjunction with its own operating channel 300 and the liquid pool. Multiple temperature control modules can be set in the array structure, and can be expanded and replicated as needed. These modules are connected in parallel to the target area requiring temperature control through their corresponding operating channels 300. To drive the array structure to work simultaneously, a power system 400 serves as the power source for multiple temperature control modules. For example, by setting a multi-channel peristaltic pump, each pump head of the peristaltic pump can drive the medium in the circulation loop of different modules.

[0055] How to use:

[0056] The compact single-flow thermal management system has two operating modes: heating and cooling.

[0057] (I) Heating Mode

[0058] When the system control core receives real-time data from the temperature sensor and determines that the current temperature T is lower than the set target value, the system automatically switches to heating mode. Taking a peristaltic pump as an example, in this mode, the controller first executes the loop configuration logic, driving the first valve 501 and the second valve 502 to open, while forcibly closing the third valve 503 and the fourth valve 504 of the refrigeration section 102. This establishes an exclusive physical path between the heating section 101 and the delivery channel 200, effectively preventing the heat source medium from accidentally entering the cold source system and causing energy loss.

[0059] Subsequently, the peristaltic pump in the power system 400 starts and is set to rotate in the "heating direction," using the pressure difference to drive the high-temperature medium out of the heating output port b, and converges into the common first channel 201 via a "T" or "Y" tee structure. After the fluid enters the working channel 300 with a spiral or cross structure, it releases heat to the target area through the efficient heat conduction characteristics of the flexible conduit. Throughout the entire cycle, the processor continuously performs closed-loop monitoring, adjusting the duty cycle of the peristaltic pump or the PID control output according to the real-time temperature difference, ensuring that after the medium completes a single heat exchange and flows back to the heat source storage system for heat compensation, the system temperature steadily rises to the target range.

[0060] (II) Cooling Mode

[0061] When the system control core receives real-time data from the temperature sensor and determines that the current temperature T is lower than the set target value, the system automatically switches to the cooling mode. Taking a peristaltic pump as an example, in this mode, the controller first executes the loop configuration logic, driving the third valve 503 and the fourth valve 504 to open, while forcibly closing the first valve 501 and the second valve 502 of the heating section 101. This establishes an exclusive physical path between the cooling section 102 and the delivery channel 200, effectively preventing the cold source medium from accidentally entering the heat source system and causing energy loss.

[0062] Subsequently, the peristaltic pump in the power system 400 starts and is set to rotate in the "heating direction," using the pressure difference to drive the cryogenic medium out from the refrigeration output port b, and converges into the common first channel 201 via a "T" or "Y" tee structure. After the fluid enters the working channel 300 with a spiral or cross structure, it absorbs heat to the target area through the efficient thermal conductivity of the flexible conduit. Throughout the cycle, the processor continuously performs closed-loop monitoring, adjusting the duty cycle of the peristaltic pump or the PID control output according to the real-time temperature difference to ensure that after the medium completes a single heat exchange and returns to the cold source storage system for heat compensation, the system temperature steadily decreases to the target range. Specific usage procedures can be found in [link to specific instructions]. Figure 5 .

[0063] In summary, this compact single-channel thermal management system comprises a front-end operating pipeline and a rear-end temperature control subsystem. The temperature control subsystem includes a temperature control module and a power control module. The temperature control module includes a refrigeration submodule and a heating submodule. Each submodule has a liquid tank, an input port, and an output port. Within the temperature control subsystem, the output port of the refrigeration module and the input port of the heating module are connected to the same operating pipeline, while the input port of the refrigeration module and the output port of the heating module are connected to the opposite operating pipeline. All four ports are equipped with check valves, which, in conjunction with the power system, control the fluid flow direction to switch between refrigeration and heating modes. A power system (such as a peristaltic pump or diaphragm pump) is installed on the delivery channel to provide forward or reverse circulation power for the medium in the circulation loop. This compact single-channel thermal management system uses a single transport channel for both heat and cold sources, simplifying the structure and volume of the direct cooling and heating pipes. This allows for a more compact size in the front-end pipes, facilitating their integration into small-scale heat dissipation structures, reducing resource waste and production costs. Driven by the power system, the circulation loop autonomously defines forward and reverse functions, enabling rapid switching between heating and cooling without altering the overall physical connections. Compared to traditional independent temperature control systems for hot and cold water, this system improves cooling and heating efficiency without requiring separate control of heating and cooling. In addition to switching between hot and cold water, this thermal management system is also suitable for the rapid switching of various working fluids in the front-end pipes.

[0064] The power control module manages the operating status of the power system, enabling automatic control of the hot and cold circulation loops. The temperature control subsystem uses temperature sensors to monitor the fluid temperature in real time and, based on temperature limits, determines the required heating or cooling state, outputting signals to control the power module. It can also adjust the pump speed to optimize fluid circulation.
