BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a radiator, and more particularly to an integrated liquid-cooling radiator.

2. Description of the Prior Art

A water-cooling radiator is configured to dissipate the heat of the radiator using a liquid under the action of a pump. Compared with air cooling, the water-cooling radiator has the advantages of quietness, stable cooling, and less dependence on the environment. The heat dissipation performance of the water-cooling radiator is proportional to the flow rate of a cooling liquid (water or other liquid). The flow rate of the cooling liquid is related to the power of the pump in the cooling system. Moreover, the heat capacity of water is large. This makes the water-cooling system have a good heat load capacity.

A conventional water-cooling heat dissipation device usually consists of a water-cooling radiator, a water-cooling block, and a water pipe. The water pipe is connected between the water-cooling radiator and the water-cooling block. The water pipe allows water in the water-cooling radiator and the water-cooling block to circulate. After the water absorbs the heat from the water-cooling block, the water flows to the water-cooling radiator for heat dissipation, and the water after heat dissipation flows back to the water-cooling block. The water-cooling radiator and the water-cooling block of the above-mentioned water-cooling radiator assembly are arranged separately. The structure is not compact, and it is inconvenient to use. The water-cooling radiator has a reservoir. The reservoir has no water pump function, which makes the water flow in the water-cooling radiator slower and the heat dissipation efficiency is low. In addition, there is no partition in the reservoir, which makes the distance of the water flow in the water-cooling radiator shorter so that the water cannot cool and dissipate heat effectively. Therefore, it is necessary to improve the conventional water-cooling radiator.

SUMMARY OF THE INVENTION

In view of the defects of the prior art, the primary object of the present invention is to provide an integrated liquid-cooling radiator, which can effectively solve the problems that the conventional water-cooling radiator is not compact in structure, inconvenient to use, poor in heat dissipation, and unable to cool the cooling liquid and dissipate heat effectively.

An integrated liquid-cooling radiator comprises a first reservoir, a second reservoir, and a plurality of radiating pipes. Two ends of the radiating pipes communicate with the first reservoir and the second reservoir, respectively. Radiating fins are provided on the radiating pipes.

The first reservoir is made of a heat-dissipating metal material. A first partition is provided in the first reservoir to divide an inside of the first reservoir into a first liquid inlet chamber and a first liquid outlet chamber. A bottom of the first reservoir is formed with a first liquid inlet communicating with the first liquid inlet chamber and a first liquid outlet communicating with the first liquid outlet chamber. The bottom of the first reservoir is provided with a thermally conductive copper sheet. A liquid inlet end of the thermally conductive copper sheet is in communication with the first liquid inlet. A liquid outlet end of the thermally conductive copper sheet is in communication with the first liquid outlet.

The second reservoir is made of a heat-dissipating metal material. A second partition is provided in the second reservoir to divide an inside of the second reservoir into a second liquid inlet chamber and a second liquid outlet chamber. The second liquid inlet chamber is provided with a liquid pump chamber. The liquid pump chamber is provided with a second liquid inlet communicating with the second liquid inlet chamber and a second liquid outlet communicating with the second liquid outlet chamber. A liquid pump is provided in the liquid pump chamber.

Some of the radiating pipes are connected between the first liquid outlet chamber and the second liquid inlet chamber. The others of the radiating pipes are connected between the first liquid inlet chamber and the second liquid outlet chamber.

Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be known from the above technical solutions:

By arranging the thermally conductive copper sheet on the first reservoir to form an integrated structure, the product has a compact structure and is more convenient to use. By providing the liquid pump in the second reservoir, the liquid pump and the second reservoir are integrated. The flow speed of the cooling liquid in the radiating pipes is effectively increased, and the heat dissipation efficiency is improved. In cooperation with the partition in each reservoir, the flow path of the cooling liquid is extended greatly, so that the cooling liquid can cool and dissipate heat effectively and sufficiently. The overall heat dissipation effect of the product is very good.

Two ends of the radiating pipes30communicate with the first reservoir10and the second reservoir20, respectively. Radiating fins60are provided on the radiating pipes30. Specifically, some of the radiating pipes30are connected between the first liquid outlet chamber103and the second liquid inlet chamber202, and the others of the radiating pipes30are connected between the first liquid inlet chamber102and the second liquid outlet chamber203. The corresponding ends of the radiating pipes30are hermetically installed in the corresponding first installation grooves106. The corresponding ends of the radiating pipes30are hermetically installed in the corresponding second installation grooves207. The radiating pipes30are arranged in a row. In addition, two fan brackets70are connected between the first reservoir10and the second reservoir20. The two fan brackets70are arranged on the left and right sides of the liquid-cooling radiator. The radiating pipes30are located between the two fan brackets70. The two fan brackets70are configured to install and fix cooling fans, so as to accelerate the heat dissipation efficiency.

The working principle of this embodiment is described in detail as follows:

When in use, a heat-generating electronic device is attached to the thermally conductive copper sheet41, and the two fan brackets70are installed with cooling fans. The heat generated when the heat-generating electronic device is working is conducted to the thermally conductive copper sheet41. At this time, the liquid pump51and the cooling fans can be turned on to dissipate heat and cool down the thermally conductive copper sheet41. Specifically, after the liquid pump51is turned on, the cooling liquid (such as water, etc.) in the product starts to circulate in the flow path. The cooling liquid with a lower temperature enters the thermally conductive copper sheet41from the first liquid inlet chamber102through the first liquid inlet104, and then the cooling liquid passes through the fins411on the thermally conductive copper sheet41to absorb the heat on the thermally conductive copper sheet41. After the cooling liquid absorbs heat, the temperature of the cooling liquid rises and the cooling liquid enters the first liquid outlet chamber103from the first liquid outlet105. Then, the cooling liquid flows into the second liquid inlet chamber202from some of the radiating pipes30in the form of multiple channels. When the cooling liquid flows through the radiating pipes30for the first time, some heat is absorbed. The heat on the radiating pipes30is dissipated by the cooling fans in time. Then, the cooling liquid enters the liquid pump chamber204through the second liquid inlet205. In the liquid pump chamber204, the cooling liquid enters the second liquid outlet chamber203through the second liquid outlet206after being pressurized. Then, the cooling liquid flows back into the first liquid inlet chamber102from the others of the radiating pipes30in the form of multiple channels. When the cooling liquid flows through the radiating pipes30for the second time, heat is absorbed again, so that the temperature of the cooling liquid is further reduced. The cooled cooling liquid passes through the first liquid inlet104and enters the thermally conductive copper sheet41again to absorb heat. This cycle repeats and continuously absorbs the heat on the thermally conductive copper sheet41to ensure that the heat-generating electronic device works normally and will not be abnormal due to excessive temperature.

FIGS.6-10show the specific structure of a second embodiment of the present invention. The specific structure of the second embodiment is substantially similar to the specific structure of the first embodiment with the exceptions described hereinafter.

In this embodiment, the radiating pipes30are arranged in front and rear two rows, so that the product has a larger cooling liquid capacity, can absorb more heat, has a better heat dissipation effect, and meets the use requirements of high-power heat-generating electronic devices.
