Description

Technical Field

[0001] The invention belongs to the technical field of chassis heat dissipation, and in particular relates to a computer chassis heat dissipation structure. Background Art

[0002] With the rapid development of information technology, the demand for high-performance computing equipment is growing, and high-performance computing equipment is often accompanied by high power consumption, which makes temperature control inside the computer a major challenge. Traditional air cooling can no longer meet the requirements of high-performance computing equipment for heat dissipation efficiency, especially when running under high load for a long time. Overheating can cause system performance degradation or even hardware damage. Therefore, in recent years, liquid cooling technology has gradually attracted attention due to its high efficiency and stability, and is widely used in data centers, supercomputers and other high-performance computing environments. The liquid cooling system uses the high specific heat capacity of liquid to absorb and transfer heat. Compared with air, liquid can take away heat more effectively, thereby achieving better heat dissipation. In addition, the liquid cooling system can also reduce noise and improve the overall stability of the system.

[0003] However, the liquid cooling systems currently on the market have certain limitations. First, since most of the heat dissipation structures use air cooling, dust easily enters the chassis. Second, in terms of heat dissipation efficiency, existing air cooling systems often fail to fully utilize the heat dissipation potential of each component, resulting in a failure to achieve optimal heat dissipation. In addition, traditional liquid cooling systems usually rely on smaller water tanks, and when the coolant inside the water tank is overheated, the cooling efficiency is low. Therefore, we propose a computer chassis heat dissipation structure. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a computer case heat dissipation structure, which cools down the water tank through a semiconductor refrigeration device to prevent the coolant from overheating and reduce dust entry into the case through water cooling.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The first circulating water pump draws the coolant cooled by the refrigeration device into the first circulating water pipe, realizing the circulation of the coolant in the system. The purpose of this step is to ensure that the coolant can be evenly distributed and cover the key heat-generating components, and take away the heat through continuous circulation. Ultimately, the effect of efficient heat dissipation is achieved, which helps to maintain the temperature of the computer's internal environment within a relatively ideal range, thereby extending the service life of the hardware and improving the overall stability of the system.

[0016] 2. By installing a lithium battery inside the computer case and continuing to power the refrigeration device after the external power supply is cut off, the function of cooling the coolant can be achieved without an external power supply. The key role of this step is to provide uninterrupted heat dissipation guarantee, ensuring that key components will not be damaged due to sudden temperature rise even in the event of a sudden power outage.

A second circulating water pipe 55 is embedded inside the metal contact plate 54 , and a second water tank 53 is fixedly connected to the right side of the metal contact plate 54 .

[0033] A power supply installation port 6 is provided on one side of the computer case 1, and a power supply air intake port 10 is provided at the lower part of the computer case 1. The power supply module is installed on the left side of the power supply installation port 6. The power supply module is a prior art and has a fan installed inside. Therefore, the power supply air intake port 10 is required at the lower part of the computer case 1.

[0034] A filter 12 is installed at the lower part of the power supply air intake port 10, and a magnet frame is fixedly connected to the outer side of the filter 12. A support foot 11 is fixedly connected to the lower part of the computer case 1. The filter 12 can prevent dust from entering the power module. The magnet frame can absorb the lower part of the computer case 1 and facilitate the removal of the filter 12.

[0035] A power display screen is provided on the front side of the lithium battery 15 for displaying the remaining power. A first hose connector 13 and a switch are provided on the first circulating water pump 14, and the power supply of the first circulating water pump 14 can be turned off when the computer is shut down.

[0036] The computer case 1 is connected to a cover plate 3 by bolts. The cover plate 3 is provided with an observation window 4 and a circular notch. The observation window 4 is used to observe the remaining power of the lithium battery 15. The circular notch is used for the switch of the first circulating water pump 14 to pass through.

The charger 9 is electrically connected to the lithium battery 15, and the charger 9 is powered by a power module. After the computer and the power module are turned off, a portion of the electricity has been charged into the lithium battery 15 to power the semiconductor refrigeration plate 73.

[0038] The refrigeration device 7 includes a semiconductor refrigeration sheet 73, which is installed inside a notch opened on the computer case 1. A first heat sink 72 and a second heat sink 74 are respectively provided on both sides of the notch. The first heat sink 72 and the second heat sink 74 are respectively fixed on the inner and outer sides of the computer case 1 and can close the notch.

[0039] A fan 71 is installed on one side of the first heat sink 72, and the right end of the second heat sink 74 extends into the interior of the first water tank 8 and is welded thereto, so as to directly contact the coolant.

[0040] Working principle: When in use, the computer case heat dissipation structure of the present invention starts to work, and firstly, the power module is cooled by the power heat dissipation device 5 installed on one side of the computer case 1. The metal contact plate 54 in the power heat dissipation device 5 is in close contact with the power module, and the second circulating water pipe 55 embedded inside drives the coolant circulation through the submersible pump 51, transfers the heat to the second water tank 53, and dissipates it into the air through the first heat dissipation aluminum sheet 52, thereby realizing effective cooling of the power module.

[0041] Next, the first water tank 8 located at the bottom of the computer case 1 stores the coolant, and the semiconductor cooling fins 73 in the refrigeration device 7 cool the coolant. The semiconductor cooling fins 73 are installed in the notch opened on the computer case 1, and the first heat sink 72 and the second heat sink 74 are respectively provided on both sides of the notch. The fan 71 installed on one side of the first heat sink 72 helps to dissipate the heat generated during the operation of the cooling fin, and the second heat sink 74 transfers the cooled temperature to the coolant in the first water tank 8, thereby keeping the coolant at a relatively low temperature.

[0042] Subsequently, the first water tank 8 is connected to the first circulating water pump 14 through a hose. After the first circulating water pump 14 is started, the coolant cooled by the refrigeration device 7 is extracted through the hose and pumped into the first circulating water pipe 2. The coolant flows through the computer case 1 during the circulation process, absorbs heat and returns to the first water tank 8, completing a cycle. In this way, through continuous circulation, the coolant takes away the heat generated by the components inside the case, achieving an efficient heat dissipation effect.

[0043] In addition, in order to ensure that the system can still operate normally when the external power supply is cut off, a lithium battery 15 is arranged inside the computer case 1. After the external power supply is cut off, the lithium battery 15 can continue to supply power to the refrigeration device 7, so that the refrigeration device 7 can still cool the coolant in the first water tank 8 when the computer is not in use, thereby preventing the coolant from overheating.

[0044] In summary, the present invention achieves efficient and reliable heat dissipation of the computer case through the above-mentioned structure and working principle, which not only effectively prevents the coolant from overheating, but also reduces the accumulation of dust inside the case through the water cooling system, thereby improving the overall performance and service life of the computer.
