[0034] Figure 2 is a schematic diagram of another integrated liquid cooling device provided by an embodiment of the present application. Detailed Embodiments

[0035] Please refer to Figure 1 and Figure 2 The present application provides an integrated liquid cooling device. In view of the characteristics of many product components and pipelines in the liquid cooling system of a helicopter, the functions and performances of the components of the liquid cooling system are analyzed to optimize the composition of the system.

[0036] First, for the liquid storage tank, its main function is to store the coolant for the liquid cooling system, while the function of the expansion tank is to store the coolant that expands due to thermal expansion and contraction. Therefore, according to the physical properties of the coolant, the expansion volume of all the coolant at the highest working temperature of the liquid cooling system is calculated, that is, the function of the expansion tank can be completed by increasing the volume of the liquid storage tank accordingly.

[0037] Second, for the air-ground conversion valve at the front end of the liquid storage tank and the electric valve at the rear end of the booster pump, the function of the air-ground conversion valve is to prevent the front-end coolant from entering the liquid storage tank when the liquid cooling system is closed, and the function of the electric valve is to prevent the rear-end coolant from entering the liquid storage tank when it is closed. Since the booster pump can be integrated at the bottom of the liquid storage tank, as long as a shut-off valve is provided on the liquid storage tank as the switch for controlling the entry and exit of the coolant into and out of the liquid storage tank, the functions of the air-ground conversion valve and the electric valve can be replaced. Therefore, the air-ground conversion valve and the electric valve can be cancelled.

[0038] Third, the function of the overflow valve is that when the cold plate of the electronic device is blocked, the high-pressure coolant in the liquid cooling system flows back to the liquid storage tank through the overflow valve to prevent the high-pressure coolant from damaging the relevant components of the electronic device. And the centrifugal booster pump is selected for this liquid cooling system. This centrifugal booster pump can keep the pressure of the outlet coolant stable. When a certain component in the liquid cooling system is blocked, this centrifugal booster pump can automatically overflow to prevent the high-pressure coolant from damaging the relevant components of the electronic device. Therefore, the overflow valve can be cancelled.

[0039] Fourth, for the temperature sensor, pressure sensor, and flow sensor at the front end of the liquid storage tank, and the pressure sensor at the rear end of the booster pump, they can be combined and integrated at the corresponding positions on the liquid storage tank and complete their original functional tasks. Therefore, after the liquid storage tank integrates the original temperature sensor, pressure sensor, flow sensor, safety valve, drain valve, centrifugal booster pump, and shut-off valve, a new liquid supply component is formed, as Figure 2 shown.

[0040] Fifth, for the temperature control valve and the manual valve, they both belong to valves. Although their functions are different, the temperature control valve is used to control the flow rate of the coolant entering the radiator, and the manual valve is used to adjust the flow rate of the entire liquid cooling system. The temperature control valve and the manual valve can be integrated on one valve. At the same time, the filter, temperature sensor, and pressure sensor at the rear end of the temperature control valve can be combined and integrated at the corresponding positions on the temperature control valve and complete their original functional tasks. Therefore, after the temperature control valve integrates the original temperature sensor, pressure sensor, filter, and manual valve, a new distribution component is formed, as Figure 2 shown.

[0041] It should be noted that for an integrated liquid cooling device provided in this application, considering the similar functional requirements of the liquid storage tank and the expansion tank, and based on the physical properties of the coolant, the expansion volume of all the coolant at the highest working temperature of the liquid cooling system is calculated. By increasing the corresponding volume of the liquid storage tank, the function of the expansion tank can be completed. Therefore, the original expansion tank can be cancelled.

[0042] Furthermore, according to the structural characteristics of the liquid storage tank, the original booster pump is integrated at the bottom of the liquid storage tank, which not only increases the system integration degree but also avoids the maintenance problems caused by the installation of a single booster pump. Considering the functional requirements of the original space conversion valve at the front end of the liquid storage tank and the electric valve at the rear end of the booster pump, a shut-off valve is set on the liquid storage tank. As the switch for controlling the coolant to enter and exit the liquid storage tank, it can replace the functions of the original space conversion valve and the electric valve. Therefore, the space conversion valve and the electric valve can be cancelled.

[0043] Among them, a centrifugal booster pump is selected for the liquid cooling system. This centrifugal booster pump can keep the pressure of the outlet coolant stable. When a certain component in the system is blocked, this centrifugal booster pump can automatically overflow, and this function can replace the function of the original overflow valve. Therefore, the overflow valve of the original liquid cooling system can be cancelled.

[0044] Meanwhile, components such as the temperature sensor, pressure sensor, flow sensor at the front end of the liquid storage tank and the pressure sensor at the rear end of the booster pump can be combined and integrated at the corresponding positions on the liquid storage tank to complete their original functional tasks. Therefore, a new liquid supply component is formed after integrating the original temperature sensor, pressure sensor, flow sensor, safety valve, drain valve, centrifugal booster pump, and shut-off valve on the liquid storage tank.

[0045] Among them, for the temperature control valve and the manual valve, they both belong to valves. Although their functions are different, the temperature control valve is used to control the flow rate of the coolant entering the radiator, and the manual valve is used to adjust the flow rate of the entire liquid cooling system. The temperature control valve and the manual valve can be integrated on one valve, which can reduce the weight of the system; in addition, the filter, temperature sensor, and pressure sensor at the rear end of the original temperature control valve can be combined and integrated at the corresponding positions on the temperature control valve to complete their original functional tasks. Therefore, a new distribution component is formed after integrating the original temperature sensor, pressure sensor, filter, and manual valve on the temperature control valve.

[0046] Furthermore, the newly integrated liquid supply component, distribution component, liquid cooling radiator, and cold plate of the electronic device are combined to form a new liquid cooling system. Since the system has been optimized modularly, a large number of liquid cooling pipeline joints have been reduced, and the possibility of system leakage has been decreased.

[0047] Furthermore, the newly integrated liquid supply component, distribution component, liquid cooling radiator, and cold plate of the electronic device are combined to form a new liquid cooling system. The entire liquid cooling system has been modularized, improving the reliability, maintainability, and supportability of the system.

[0048] In this application, through the analysis of the functions and performances of the components of the original liquid cooling system, the components of the original liquid cooling system are optimized and integrated.

[0049] First, on the basis of the original liquid cooling system, components such as the expansion tank, air-ground transfer valve, electric valve, and overflow valve are cancelled; second, the original temperature sensor, pressure sensor, flow sensor, safety valve, drain valve, centrifugal booster pump, and newly added shut-off valve are integrated on the liquid storage tank to form a new liquid supply component; finally, the original temperature sensor, pressure sensor, filter, and manual valve are integrated on the temperature control valve to form a new distribution component.

[0050] The entire liquid cooling system has been modularized, greatly simplifying the configuration of the system, reducing the number of liquid cooling pipelines and pipe joints, decreasing the possibility of coolant leakage, and improving the reliability, maintainability, and supportability of the liquid cooling system.

[0051] In other embodiments of this application, please refer to Figure 1 , an integrated liquid cooling device provided by this application includes a liquid supply component, a distribution component, a liquid cooling radiator, and a cold plate of the electronic device.

[0052] The working principle of this application is as follows:

[0053] When the liquid cooling system starts to work, the system first opens the shut-off valve and then starts the booster pump. The coolant in the liquid storage tank is pressurized by the booster pump and flows through the shut-off valve, manual valve, and temperature control valve. One part flows into the liquid cooling radiator to exchange heat with the forced convection air for cooling, and the other part does not flow through the liquid cooling radiator. The two parts of the coolant are mixed after the outlet of the liquid cooling radiator, flow through the filter, enter the cold plate of the electronic device, exchange heat with the cold plate and then the temperature rises. Then, after passing through the flow sensor and shut-off valve, it enters the liquid storage tank to complete a working cycle. After the work is completed, the system first shuts down the booster pump and then closes the shut-off valve.

[0054] When the system is working, the extra volume of the liquid storage tank can compensate for the expansion volume of the coolant with the increase in temperature, preventing the coolant from overflowing outside the liquid storage tank; when the cold plate of the electronic device is blocked, as the pressure of the coolant in the system reaches the output limit value of the booster pump, the booster pump automatically overflows part of the coolant at the outlet back to the liquid storage tank. At the same time, each temperature sensor, pressure sensor, and flow sensor of the liquid cooling system collects relevant data in real time. When the liquid cooling system stops working and the ground liquid cooling vehicle is connected to the self-sealing valve, the shut-off valve of the liquid cooling system is in the closed state to prevent the coolant in the ground liquid cooling vehicle from flowing into the liquid storage tank and the liquid cooling radiator through the shut-off valve.
