Description

Technical Field

[0001] This invention relates to the field of liquid cooling technology, and in particular to a heat-driven liquid cooling system based on the torsional thermal effect and its control method. Background Technology

[0002] In current cooling applications, vapor compression refrigeration technology dominates. This technology relies on the phase change process of chemical refrigerants, releasing latent heat through liquid-gas conversion to achieve a cooling effect. However, the widespread use of these refrigerants has caused serious environmental problems, such as global warming and ozone layer depletion. To address these challenges and alleviate the increasingly severe energy crisis, solid-state cooling technology that does not require traditional refrigerants has emerged, especially suitable for specific application scenarios.

[0003] Solid-state cooling technologies mainly include magnetothermal, elasto-thermal, compressive, and electrothermal cooling, driven by magnetic fields, stress, hydrostatic pressure, and electric fields, respectively. Among them, elasto-thermal cooling has attracted much attention due to its excellent temperature change effect, significant thermal effect, and simplified driving mechanism. As a special form of elasto-thermal cooling, torsional cooling utilizes the phase transformation from austenite to martensite during the torsion process to achieve temperature increase, while the transformation from martensite to austenite upon release of the torsion leads to temperature decrease. In practical applications, the cooling effect of torsional cooling materials mainly originates from the temperature decrease phase, while the heat generated during the temperature increase phase needs to be dissipated promptly. Torsional cooling materials require external torque input to generate a thermal effect, which increases energy consumption. Therefore, how to achieve effective torsion of torsional cooling materials with minimal energy has become a major research challenge. Summary of the Invention

[0005] The objective of this invention is achieved through the following technical solution:

[0044] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0045] Example

[0046] like Figure 1 As shown, a heat-driven liquid cooling system based on the torsional thermal effect includes a high-temperature working fluid circulation loop and a low-temperature working fluid circulation loop. The high-temperature working fluid circulation loop consists of a driving heat source 1, a cooling heat exchanger 2, a first circulation pump 8, a second circulation pump 10, a first two-position four-way solenoid valve 7, a second two-position four-way solenoid valve 9, an upper flow channel 4, and a lower flow channel 5. The low-temperature working fluid circulation loop consists of a cooling heat exchanger 2, a heat exchanger 3, a third circulation pump 12, a fourth circulation pump 14, a first two-position three-way solenoid valve 11, a second two-position three-way solenoid valve 13, a heat-driven torsional thermal effect cooling device 6, and a temperature sensor 15.

[0047] The driving heat source continuously provides a high-temperature working fluid. The heat exchanger dissipates the heat from the working fluid into the environment. The cooling heat exchanger cools the liquid. The upper and lower flow channels heat or dissipate heat to drive the shape memory alloy. The first two-position four-way solenoid valve and the second two-position four-way solenoid valve change the high-temperature working fluid circulation loop. The first two-position three-way solenoid valve and the second two-position three-way solenoid valve change the low-temperature operating circulation loop. The temperature sensor measures the temperature of the working fluid in the driving heat source.

[0048] Figure 2 This is a schematic diagram of the structure of a heat-driven torsion effect device, including two identical branches. Each branch includes a heat-driven torsion module 601, a torsion effect module 602, and a connecting shaft 603. The heat-driven torsion module 601 is connected to the torsion effect module 602 via the connecting shaft 603, and the heat-driven torsion module 601 is used to provide the torque required by the torsion effect module 602.

[0049] The thermally driven torsion module 601 includes a speed increaser 601-a, a coupling 601-b, a follower wheel 601-c, a thermally driven shape memory alloy 601-d, a flow channel body 601-e, and a bearing seat 601-f.

[0050] The speed increaser 601-a, coupling 601-b, follower wheel 601-c, and bearing housing 601-f are sequentially connected as a single unit. Multiple heat-driven shape memory alloy (HMO) rings 601-d are fixed to the follower wheel 601-c. The upper part of the HMO 601-d is placed in the upper flow channel 4, and the lower part is placed in the lower flow channel 5. The two branches are interconnected through the main flow channel body 601-e, which is connected to both the upper flow channel 4 and the lower flow channel 5. The speed increaser 601-a is used to increase the output speed. The follower wheel 601-c converts the displacement of the HMO 601-d into torsion. The follower wheels of the two branches are located on both sides of the main flow channel body.

[0051] The torsional heat effect module 602 includes a rotary clamping member 602-a, a water inlet fixing member 602-b, a torsional heat effect element 602-c, a fixed clamping member 602-d, a clamping screw 602-e, a pagoda connector 602-f, and a hose 602-g. The water inlet fixing member 602-b and the fixed clamping member 602-d have cavities inside, and the pagoda connector 602-f is installed at the inlet and outlet of each cavity, respectively. A liquid channel is formed inside the pagoda connector 602-f, the water inlet fixing member 602-b, the hose 602-g, and the fixed clamping member 602-d, and the torsional heat effect element 602-c is installed inside the liquid channel. One end of the torsional heat effect element 602-c is fixed inside the rotary clamping member 602-a by the clamping screw 602-e, and the other end is clamped inside the fixed clamping member 602-d by the clamping screw 602-e. The rotary clamping member 602-a is used to provide torque to the torsional heat effect element 602-c.

[0052] In the initial state of the system, the driving heat source 1 stores a high-temperature working fluid, the cooling heat exchanger 2 stores a liquid working fluid, and the heat exchanger 3 stores a room-temperature working fluid. The temperature of the high-temperature working fluid in the driving heat source 1 is higher than the temperature of the liquid working fluid in the cooling heat exchanger 2. The shape memory alloy is installed at a temperature higher than the ambient temperature but lower than the driving heat source temperature. In this state, if the shape memory alloy comes into contact with the high-temperature working fluid in the driving heat source 1, it will elongate due to heat; if it comes into contact with the liquid working fluid in the cooling heat exchanger 2, it will contract.

[0053] During system operation, in the first half of the cycle, the high-temperature working fluid driving heat source 1 flows into the upper channel, while the liquid working fluid in the cooling heat exchanger 2 flows into the lower channel. This causes the upper part of the thermally driven shape memory alloy 601-d to be heated and the lower part to be cooled, resulting in contraction and driving the torsional heat effect element 602-c to twist and heat up. At the same time, the liquid working fluid in the cooling heat exchanger 2 flows into the thermally driven torsional heat effect cooling device 6, is heated, and then flows into the heat collection heat exchanger 3, where it dissipates the heat into the environment. In the second half of the cycle, the high-temperature working fluid of the driving heat source 1 flows into the lower channel, and the liquid working fluid in the cooling heat exchanger 2 flows into the upper channel. This causes the lower part of the thermally driven shape memory alloy 601-d to expand when heated and the upper part to contract when cooled, resulting in a torsion in the opposite direction to the first half of the cycle. This drives the torsional heat effect element 602-c to de-torsion and cool down. At the same time, the liquid working fluid in the heat exchanger 3 flows into the thermally driven torsional heat effect cooling device 6 and, after cooling down, flows into the cooling heat exchanger 2. It mixes with the high-temperature working fluid of the driving heat source 1 flowing into the cooling heat exchanger 2, thereby reducing the temperature of the liquid working fluid in the cooling heat exchanger 2.

[0054] The system operates as follows:

[0055] like Figure 3 As shown, during system operation, when the temperature sensor 15 inside the driving heat source 1 detects the temperature T of the internal working fluid... 液 and the set temperature T 设 Compare, if T 液 Less than or equal to T 设 If T 液 Greater than T 设 Then, the first circulation pump 8, the second circulation pump 10, and the third circulation pump 12 are started, and the first two-position four-way solenoid valve 7 and the second two-position three-way solenoid valve 13 are energized. The device operates for time t. 工Start timing. At this time, the high-temperature working fluid driving the heat source 1, under the action of the first circulating pump 8, first passes through the first two-position four-way solenoid valve 7, and then flows through the upper flow channel 4 to heat the upper thermally driven shape memory alloy 601-d, causing it to elongate after being heated. At the same time, the liquid working fluid in the cooling heat exchanger 2, under the action of the second circulating pump 10, first flows through the second two-position four-way solenoid valve 9, and then flows through the lower flow channel 5 to cool the lower thermally driven shape memory alloy 601-d, causing it to shrink after cooling down. At this time, the upper thermally driven shape memory alloy 601-d elongates due to heating, and the lower thermally driven shape memory alloy 601-d shrinks due to cooling, causing the two follower wheels 601-c fixed to it to rotate in opposite directions, one in the forward direction and the other in the reverse direction. The rotation of the follower wheel 601-c causes the coupling 601-b, the speed increaser 601-a, and the connecting shaft 603 to rotate accordingly, thereby driving the rotating clamping part 602-a of the torsional heat effect module 602 to rotate. The torsional heat effect element 602-c is twisted under the action of the rotating clamping member 602-a and the clamping screw 602-e. At this time, the working fluid in the cooling heat exchanger 2 first passes through the first two-position three-way solenoid valve 11 under the action of the third circulation pump, and then flows into the liquid channel of the torsional heat effect module 602. The temperature of the torsional heat effect element 602-c will rise when it is twisted, which will cause the temperature of the flowing working fluid to rise. The working fluid with the increased temperature finally flows into the heat exchanger 3, and the fan in the heat exchanger 3 will dissipate the heat to the environment.

[0056] like Figure 4 As shown, at the same time, the control unit will control the operating time t of the component device. 工 With the set period t 周 Compare one-half of t, when t 工 Greater than or equal to t 周At this time, the first two-position four-way solenoid valve 7 and the first two-position three-way solenoid valve 13 are de-energized, the third circulation pump 12 is closed, the fourth circulation pump 14 is started, and the second two-position four-way solenoid valve 9 and the first two-position three-way solenoid valve 11 are energized. At this time, the high-temperature working fluid driving the heat source 1 flows through the first two-position four-way solenoid valve 7 under the action of the first circulation pump 8, and then flows through the lower flow channel 5 to heat the lower thermally driven shape memory alloy 601-d, causing it to elongate after being heated. The room-temperature working fluid in the heat exchanger 3 flows through the second two-position four-way solenoid valve 9 under the action of the second circulation pump 10, and then flows through the upper flow channel 4 to cool the upper thermally driven shape memory alloy 601-d, causing it to shrink after cooling down. At this time, the upper thermally driven shape memory alloy 601-d contracts due to cooling, while the lower thermally driven shape memory alloy 601-d elongates due to heating. This causes the two follower wheels 601-c fixed to it to rotate in the opposite direction compared to the first half of the working cycle. The rotation of the follower wheels 601-c causes the coupling 601-b, the speed increaser 601-a, and the connecting shaft 603 to rotate accordingly. This, in turn, drives the rotating clamping member 602-a of the torsional thermal effect module 602 to rotate. The torsional thermal effect element 602-c is then released from its torsion by the rotating clamping member 602-a and the clamping screw 602-e. At this time, the working fluid in the heat exchanger 3, under the action of the fourth circulation pump 14, first passes through the first two-position three-way solenoid valve 13, and then enters the liquid channel of the torsional heat effect module 602. When the torsional heat effect element 602-c is de-torsed, its temperature drops, causing the temperature of the flowing working fluid to drop. The working fluid with the lower temperature finally flows into the cooling heat exchanger 2, where it mixes with the high-temperature working fluid flowing into the cooling heat exchanger 2 from the driving heat source 1, thereby reducing the temperature of the liquid working fluid in the cooling heat exchanger 2. This completes one cycle of the device.

[0057] like Figure 5 As shown, this embodiment also provides a control method for a heat-driven liquid cooling system based on the torsional thermal effect, including:

[0058] The P01 system operates by determining whether to activate the circulating pumps and solenoid valves based on the temperature in the cooling heat exchanger 2, and by collecting the temperature T in the driving heat source 1. 液 and device working time t 工 Execute P02;

[0059] P02 determines the temperature T in the driving heat source 1. 液 Is it greater than the set cooling temperature T? 设 If the value is greater than the specified value, proceed to P03. Otherwise, proceed to P01.

[0060] P03 starts the first circulation pump 8, the second circulation pump 10, and the third circulation pump 12, energizes the first two-position four-way solenoid valve 7, and energizes the second two-position three-way solenoid valve 13. 工 Start timing, execute P04;

[0061] P04 Determines the working time t of the device 工 Is it greater than the set period t? 周 If it is half of the value; if it is greater than the value, execute P05; otherwise, execute P04.

[0062] P05 de-energizes the first two-position four-way solenoid valve 7, de-energizes the second two-position three-way valve 13, shuts down the third circulation pump 12, starts the fourth circulation pump 14, energizes the second two-position four-way solenoid valve 9, energizes the first two-position three-way solenoid valve 11, and executes P06.

[0063] P06 Determines the working time of the determination device t 工 Is it greater than the set period t? 周 If the result is greater than the specified value, proceed to P07; otherwise, proceed to P06.
