Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid cooling system technology, specifically to a liquid cooling system with throttling and pressure relief and automatic liquid replenishment functions. Background Technology
[0002] Pressure management and level control are crucial in industrial systems and equipment. Particularly in liquid cooling systems, excessive pressure or insufficient coolant can cause unit malfunctions. Currently, common pressure relief devices are mostly simple safety valves or relief valves, with limited functionality. They passively relieve pressure when it exceeds a set value, lacking fine-tuning of the relief process and prone to causing excessive system pressure fluctuations, affecting system stability. As for level control, most systems use various types of level gauges. This method lacks accuracy and struggles to ensure optimal real-time levels. Level discrepancies can easily lead to a series of problems, such as liquid overflow causing environmental pollution and equipment damage, or insufficient level causing abnormal equipment operation or even shutdown.
[0003] Existing technologies mostly use safety valves or pressure relief valves for pressure relief. When pressure is relieved, the system pressure changes instantaneously. If there is no throttling device, it may cause safety hazards such as equipment vibration, pipeline rupture, and coolant leakage. At the same time, the pressure relief device will also be subjected to a large impact, which can easily cause damage to the device and coolant leakage, thereby reducing the reliability of the equipment and affecting the operation of the unit.
[0004] Furthermore, most existing solutions use level gauges to monitor the unit, triggering an alarm when the system level is insufficient, requiring manual replenishment. Manual replenishment suffers from latency and is difficult to precisely control the replenishment amount, easily leading to over- or under-replenishment, which affects the normal operation of the system and product quality.

[0021] The present invention will be further described in conjunction with the following embodiments.
[0022] Depend on Figures 1 to 2 As can be seen, the liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions described in this embodiment includes a water tank 1, a water pump 2, a liquid storage tank, and a cooling pipe 3; the outlet of the water pump 2 is connected to the cooling pipe 3; the water tank 1 is provided with a first valve 11; a liquid replenishment pipe 12 is provided between the first valve 11 and the inlet of the water pump 2; a throttling and pressure relief assembly is provided between the cooling pipe 3 and the water tank 1; the cooling pipe 3 is connected to the liquid storage tank; the liquid storage tank is not shown in the figure.
[0023] The throttling and pressure relief assembly includes a safety valve 42 and a throttling element 43; the throttling element 43 is provided with a throttling channel 44; the inlet of the throttling element 43 is connected to the cooling pipe 3; the outlet of the throttling element 43 is connected to the inlet of the safety valve 42; the radius of the throttling channel 44 is smaller than the radius of the inlet of the safety valve 42; a throttling and pressure relief pipe 5 is provided between the outlet of the safety valve 42 and the water tank 1.
[0024] Specifically, the liquid cooling system with throttling and pressure relief functions described in this embodiment can relieve pressure on the system when the system pressure is too high. When the system pressure is too high, the coolant is introduced into the water tank 1 through the cooling pipe 3 and the throttling and pressure relief component. When the liquid level in the system storage tank is insufficient, the first valve 11 of the water tank 1 is opened, and the unit controls the water pump 2 to send the coolant stored in the water tank 1 back to the cooling pipe 3 and the storage tank, thereby achieving the function of automatic liquid replenishment. In addition, the water tank 1 can be manually replenished at regular intervals to ensure that the system will not reduce its working efficiency due to insufficient coolant. This achieves accurate measurement and automatic liquid replenishment of the system, while reducing the unit's operating and maintenance costs.
[0025] In addition, this embodiment provides a throttling element 43 between the cooling pipe 3 and the safety valve 42, and a throttling channel 44 with a small radius is provided through the throttling element 43. This allows the high-pressure coolant in the cooling pipe 3 to first pass through the throttling channel 44 of the throttling element 43 to limit the flow rate and reduce the velocity, and then be discharged to the water tank 1 through the safety valve 42 and the throttling and pressure relief pipe 5. Since the pressure of the fluid will decrease significantly and the flow rate will increase if the flow cross-sectional area suddenly decreases when the fluid is flowing in the pipe, the throttling channel 44 with a small radius is provided to achieve the function of throttling and pressure reduction.
[0026] This embodiment describes a liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions. The liquid storage tank is equipped with a liquid level sensor. The liquid level sensor is not shown in the figure. This configuration allows for real-time detection of the liquid level in the storage tank, enabling timely replenishment.
[0027] This embodiment describes a liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions. The cooling pipe 3 is equipped with a pressure sensor 6. This configuration allows for real-time detection of the system pressure. When the system pressure is too high, the high-pressure coolant in the cooling pipe 3 first passes through the throttling channel 44 of the throttling element 43 to reduce its flow rate, and then, after passing through the pressure relief function of the safety valve 42, is discharged to the water tank 1 through the throttling and pressure relief pipe 5. Alternatively, the safety valve 42 can be replaced with a mechanical or electromagnetic pressure relief valve, which can be directly controlled to open and close via a pressure signal.
[0028] This embodiment describes a liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions.

The outlet of the second valve 41 is connected to the inlet of the safety valve 42 via a throttling channel 44. The radius of the throttling channel 44 is smaller than the radius of the outlet of the second valve 41. This design facilitates subsequent maintenance; when it is necessary to disassemble and replace the safety valve 42 or to inspect the water tank 1, the second valve 41 can be manually closed to prevent system leakage.
[0029] This embodiment describes a liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions. The first valve 11 is an electric ball valve, located at the bottom of the water tank 1. The electric ball valve 11 facilitates on / off control, and its location at the bottom of the water tank 1 allows for easy extraction of coolant.
[0030] In this embodiment, a liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions is described, wherein the second valve 41 is an electric valve. The second valve 41 is configured as an electric ball valve for easy control of its on / off state based on pressure signals.
[0031] This embodiment describes a liquid cooling system with throttling and pressure relief functions and automatic liquid replenishment. The throttling and pressure relief pipe 5 is connected to the top of the water tank 1. This configuration facilitates the delivery of coolant to the water tank 1.
[0032] This embodiment describes a liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions, wherein the water pump 2 is a plunger pump. This configuration is suitable for applications requiring high pressure, high flow rate, and flow regulation.
[0033] This embodiment describes a liquid cooling system with throttling, pressure relief, and automatic liquid replenishment functions. The bottom of the throttling element 43 is threadedly connected to the second valve 41; the top of the throttling element 43 is threadedly connected to the safety valve 42. This arrangement facilitates the assembly and disassembly of the throttling element 43 and the safety valve 42.
