Abstract

The present invention provides a liquid cooling system used in a machine box, which performing cool down the extracted air, and then send it outside. The present invention includes a first housing, a second housing, a fan and a liquid heat exchanger. The fan and the liquid heat exchanger are covered in the first housing and the second housing. The air is guarded into the fan, and pass through the liquid heat exchanger so that the thermal energy contained in the air is carried away by the liquid heat exchangerfor avoiding large amplitude boost of temperature for discharging air.

Description

Liquid cooling system for a chassis and a chassis thereof

The invention relates to a chassis with cooling effect, in particular to a liquid cooling system which can be used for placing a server and a chassis formed therewith.

The combination of computer and network brings a lot of convenience, such as information collection, online shopping, email or entertainment, can be carried out using computers and the Internet. In addition, when handheld electronic devices can enter the Internet through 3G or other wireless network systems, and the concept of cloud is gradually matured and introduced into life, the load of servers for accessing data is relatively increased. Therefore, the server The number is also relatively increased.

However, in the process of high-speed operation, the electronic components in the server generate high thermal energy, and if they are not excluded, the electronic components will be burned and the like. Referring to the cross-sectional view of the conventional server chassis 90 shown in FIG. 1, the chassis 90 has a plurality of compartments 91. Each compartment 91 is provided with a fan 911. Each compartment 91 is used by the fan 911. The air inside is drawn out to create a circulation of air so that the heat energy does not stay inside.

The above-mentioned conventional chassis 90 can carry out the internal heat energy, but there is no other subsequent processing after being taken out, and the server will continue to be powered on, so that the heat energy is continuously generated and stayed in the chassis 90. Around, the resulting air is still hot air with thermal energy, making the components inside the server easy to burn.

Although some computer rooms use air-conditioning to continuously blow and cool down, in the era of limited energy, this will not only waste the earth's resources, but also increase the cost of electricity. For the era of increasing server usage, the above issues need to be addressed.

In order to solve the above problems, the present invention provides a liquid cooling system for a chassis, which can cool the air extracted from the server, so that air containing heat energy can be prevented from entering the chassis again, thereby achieving the effect of protecting the server. .

The invention includes a first housing, a second housing, a fan and a liquid heat exchanger. The first housing is provided with a first venting hole; the second housing is provided with a second venting hole, and the second housing is coupled to the first housing; the fan is coupled to the first housing, And corresponding to the position of the first vent. The liquid heat exchanger is coupled to the second housing and adjacent to the fan, and comprises a box body, an inlet and an outlet, the box body is a metal material, and has a first tube body group therein a second tube group, the first tube group comprising a plurality of first tubes, the first tube systems being adjacent to each other in parallel and concentrated on one side of the box body, the second tube group being respectively a plurality of second tubes are disposed, and the second tubes are adjacent to each other in parallel and concentrated on the other side of the housing, and the first tube group is in communication with the second tube group; the inlet Connected to the first tube group; the outlet is connected to the second tube group; after the liquid flows in from the inlet, it will flow along the first tube group into the second tube group and flow out from the outlet.

After the invention is incorporated into the chassis of the loading server, the heat energy in the server can be cooled before being discharged out of the chassis, so that the temperature around the chassis does not rise significantly, nor does the hot air pass through the cycle again. Inside the server. Moreover, the present invention can be responsible for a plurality of servers by using only one fan, and it is not necessary to adopt a one-to-one method (that is, a server corresponds to a fan), thereby improving the convenience of maintenance and thus being environmentally friendly. effect.

Furthermore, another object of the present invention is to provide a chassis having a liquid cooling system that combines a case with at least one of the aforementioned liquid cooling systems for the chassis for generating a server placed in the chassis. The heat is cooled and discharged.

In the following, a preferred embodiment, in conjunction with the drawings and component symbols, will be described in detail as follows:

Referring to FIG. 2 to FIG. 3 , a liquid cooling system for a chassis of the present invention includes a first housing 10 , a second housing 20 , a fan 30 , and a liquid heat exchanger. 40.

The first housing 10 is provided with a first ventilation hole 11 , the second housing 20 is provided with a second ventilation hole 21 , and the second housing 20 can be coupled with the first housing 10 . The fan 30 is coupled to the first housing 10 and corresponds to the position of the first vent hole 11. Thereby, air can be taken in and out from the first vent hole 11 and the second vent hole 21.

Please refer to FIG. 4 and FIG. 5 simultaneously. The liquid heat exchanger 40 is coupled to the second casing 20 and adjacent to the fan 30. The liquid heat exchanger 40 includes a casing 41, an inlet 42 and an outlet 43.

The box body 41 is made of a metal material, and has a first tube body group 411 and a second tube body group 412 therein. The first tube body group 411 includes a plurality of first tube bodies 411A, and the first tube tubes 411A. The body 411A is adjacent to each other in parallel and concentrated on one side of the casing 41. The second pipe body group 412 includes a plurality of second pipe bodies 412A, respectively, and the second pipe bodies 412A are adjacent to each other in parallel. Concentrating on the other side of the casing 41, and the first tubular body group 411 is in communication with the second tubular body group 412; the inlet 42 is connected to the first tubular body group 411, and the outlet 43 is connected to The second tube set 412. After the liquid flows in from the inlet 42, it flows into the second tube group 412 along the first tube group 411 and then flows out from the outlet 43. Thereby, the first tube group 411 can be configured to absorb the thermal energy in the air by the large-area cooling liquid, and then the thermal energy can be carried out from the outlet 43 via the second tube group 412 to reduce the passage. The temperature of the air, therefore, can lower the temperature of the emitted gas. In addition, the liquid heat exchanger 40 can be connected to the liquid input device and the liquid recovery device, etc., respectively, at the inlet 42 and the outlet 43 for heat exchange, which is a general technology of the heat exchanger, and all personnel engaged in the industry It can be directly understood, so it will not be repeated here, and it will be described first.

The present embodiment is combined with a case B to form a chassis having a liquid cooling system. Referring to FIG. 6 and FIG. 7, the box B is combined with the liquid cooling system described above. Due to the strong cooling capability of the present invention, a fan can achieve the effect of dissipating heat to a plurality of servers, and Since the temperature of the delivered air has been lowered, that is, the heat energy has been taken away by the liquid heat exchanger 40, there is no problem that the hot air is sucked in again.

Moreover, as shown in FIG. 8, two liquid cooling systems for the chassis can be combined in one case B, thereby enhancing the effect.

Moreover, as shown in FIG. 9, the first casing 10 may face the outside of the casing B, even if the extracted hot air first passes through the liquid heat exchanger 40, so that the liquid heat exchanger 40 can directly contact the liquid heat exchanger 40. The internal environment of the cabinet B is outputted by simultaneously transmitting part of the thermal energy through the contact, thereby increasing the efficiency of heat exchange.

The above is only the detailed description and drawings of the specific embodiments of the present invention, and is not intended to limit the invention, the scope of the invention should be limited to the following claims.
