TECHNICAL FIELD

The present disclosure belongs to the technical field of water cooling radiators, and particularly relates to a water cooling head, a water cooling radiator and an electronic equipment.

BACKGROUND

High temperature is the enemy of integrated circuits. High temperature will not only lead to unstable system operation, shortened service life, and even burn certain parts. The role of the radiator is to absorb the heat to ensure that the temperature of computer parts is normal. According to cooling methods, radiators can be divided into air cooling radiators, heat-piped radiators, water cooling radiators, semiconductor cooling radiators, and compressor cooling radiators, etc. Among them, the water cooling radiator uses a forced circulation of a cooling liquid to take away the heat of the radiator under the driving of a water pump. Compared with the air cooling radiators, it has the advantages of quietness, stable temperature reduction, and low dependence on the environment.

However, the water cooling head of the existing water cooling radiator is generally provided with only one water pump with an impeller. The cooling liquid flow capacity of a single water pump is limited, and thus the existing water cooling radiator has a poor heat dissipation effect. In addition, when the water pump fails, the water cooling radiator cannot continue to work normally, and this easily causes the CPU (Center Processing Unit) of an electronic device to be burnt out.

In order to make the technical problems, technical solutions and beneficial effects solved by the present disclosure clearer, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

As shown inFIG. 1, a water cooling radiator provided by an embodiment of the present disclosure includes a water tank200, a water inlet pipe300, a water outlet pipe400, and a water cooling head100. The water inlet pipe300is connected between a water outlet201of the water tank200and a water inlet115of the water cooling head100, and the water outlet pipe400is connected between a water inlet202of the water tank200and a water outlet116of the water cooling head100.

As shown inFIGS. 1-15, the water cooling head100according to an embodiment of the present disclosure includes a center module1, a first water pump2, a second water pump3, and a heat exchange module4. The center module1is provided with a first water inlet channel118, a second water inlet channel119, a first water outlet channel113, a second water outlet channel114, the water inlet115, and the water outlet116. A first water pump2, a second water pump3, and the heat exchange module4are respectively mounted on the center module1. A first water cavity5is enclosed between the first water pump2and the center module1, a second water cavity6is enclosed between the second water pump3and the center module1, and a third water cavity7is enclosed between the heat exchange module4and the center module1.

A first water inlet channel118and a second water inlet channel119communicate with the water inlet115, respectively. The first water cavity5communicates between the first water inlet channel118and the first water outlet channel113. The second water cavity6communicates between the second water inlet channel119and the second water outlet channel114. The first water outlet channel113and the second water outlet channel114communicate with the third water cavity7, respectively. The third water cavity7communicates with the water outlet116.

The first water pump2is used to introduce the cooling liquid from the water inlet115which passes through the first water inlet channel118, the first water cavity5, the first water outlet channel113, and the third water cavity7in sequence, and discharge the cooling liquid from the water outlet116.

The second water pump3is used to introduce the cooling liquid from the water inlet115which passes through the second water inlet channel119, the second water cavity6, the second water outlet channel114, and the third water cavity7in sequence, and discharge the cooling liquid from the water outlet116.

The heat exchange module4is used to perform heat exchange on the cooling liquid which flows through the third water cavity7.

The water cooling head100according to the embodiment of the present disclosure drives the cooling liquid to flow by two water pumps (the first water pump2and the second water pump3), so that the cooling liquid can flow into the water cooling head100from the water inlet115under the action of the two water pumps. After that, a part of the cooling liquid flows through the first water inlet channel118and into the first water cavity5under the action of the first water pump2, and then flows through the first water outlet channel113and into the third water cavity7. Another part of the cooling liquid flows through the second water inlet channel119and into the second water cavity6under the action of the second water pump3, and then flows through the second water outlet channel114and into the third water cavity7. The cooling liquid entering the third water cavity7is subjected to heat exchange by the heat exchange module4, and finally flows out from the water outlet116.

The existing cooling liquid in the first water cavity5flows through the first water outlet channel113and into the third water cavity7, is cooled by the heat exchange module4, and then flows out from the water outlet116.

When the impeller31of the second water pump3rotates, the existing cooling liquid in the second water cavity6will flow in the direction of rotation of the impeller31of the second water pump3. The cooling liquid is driven to flow from the water inlet115, through the second water inlet channel119, and into the second water cavity6.

when the water cooling radiator works, the first water pump2and the second water pump3in the water cooling head100work, driving the impeller21of the first water pump2and the impeller31of the second water pump3to rotate, thereby driving the cooling liquid to flow from the water tank200, through the water outlet201of the water tank200, the water inlet pipe300, and the water inlet115of the water cooling head100in sequence, and into the water cooling head100.

A part of the cooling liquid entering the water cooling head100flows through the first water inlet channel118, the first water cavity5, the first water outlet channel113and the flow guiding hole132of the flow guiding plate13in sequence, and into the third water cavity7. Another part flows through the second water inlet channel119, the second water cavity6, the second water outlet channel114and the flow guiding hole132of the flow guiding plate13in sequence, and into the third water cavity7.

The cooling liquid flowing into the third water cavity7is cooled by the foamy copper, and then flows from the water outlet116, through the gap134(shown inFIG. 9) between the flow guiding plate13and the foamy copper, and flows out from the water cooling head100.

The cooled cooling liquid flowing out from the water cooling head100flows back into the water tank200through the water outlet pipe400and the water inlet202of the water tank200, so that the water tank200cools down the electronic devices.

The electronic equipment according to an embodiment of the present disclosure includes the above-mentioned water cooling radiator, and further includes a CPU and a CPU radiator500for radiating the CPU. The water tank200is fixedly connected to the CPU radiator500. The cooling liquid in the water tank200is used to cool the CPU radiator500.

When the water cooling radiator is mounted on the electronic equipment, to better achieve the cooling effect, the center axis of the impeller21of the first water pump2may be configured to be not perpendicular to the plane where the CPU of the electronic equipment is located, and the impeller31of the second water pump3may be configured to be not perpendicular to the plane where the CPU of the electronic equipment is located. In an embodiment, the electronic equipment according to the embodiment of the present disclosure may be a computer or a server. That is, the water cooling radiator and the water cooling head100according to the embodiment of the present disclosure can be applied in the computer or server industry.

Further, unless otherwise required by context, singular terms shall include pluralities and plural terms shall include the singular. Thus, as used herein and in the claims, the singular forms include the plural reference and vice versa unless the context clearly indicates otherwise.

The above description is only the preferred embodiments of the present disclosure and is not intended to limit the present disclosure. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present disclosure shall be included in the scope of the protection of the present disclosure.
