Description

Technical Field

[0001] This utility model relates to the field of water cooling technology, specifically a heat dissipation water duct that prevents crossflow. Background Technology

[0002] A cooling radiator is a heat dissipation structure installed in high heat density devices such as computers and servers. It works by having a cold plate contact the heat-generating element and then connecting the cold plate to the cooling radiator via water pipes to achieve refrigerant circulation. The high heat dissipation efficiency of the radiator is then utilized by a fan to accelerate airflow over its surface, thereby achieving efficient heat dissipation.

[0003] A search revealed a published patent with publication number CN220473949U, which relates to a water-cooled radiator with an external interface. The radiator includes a first and a second water storage chamber located at both ends, and a cooling pipe connecting the two chambers. The first water storage chamber is divided into a third, fourth, and fifth water storage chamber by a partition. The radiator's end face has a first and a second interface. The first interface connects to the fifth water storage chamber, and the second interface connects to the fourth water storage chamber. The first and second interfaces are connected via an external component. By using the external component, the water-cooled radiator can achieve diverse functions. For example, if the external component is a water pump, it integrates the pump and the radiator. If a connecting pipe is used, it functions as a regular water-cooled radiator. Furthermore, cooling fins can be added, or another radiator can be connected in series to further improve the overall system's heat dissipation performance.

[0004] The water drainage structure using the above technology requires the use of partitions to form multiple water storage chambers. However, due to the influence of processing and assembly processes, too many chambers can lead to difficulty in ensuring sealing and can easily cause cross-flow between water outlet chambers, resulting in a significant reduction in overall performance. At the same time, the overly complex internal partition structure also increases the processing difficulty and manufacturing cost. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat dissipation water duct that prevents crossflow, comprising a water duct body, a first water storage chamber for refrigerant circulation at the end of the water duct body, a water pump fixedly installed on the top of the first water storage chamber, one inlet / outlet of the water pump being arranged vertically and connected to the first water storage chamber, and the other inlet / outlet of the water pump being extended horizontally.

[0006] Furthermore, one inlet of the water pump is arranged vertically and connected to the first water storage chamber, and the outlet of the water pump extends horizontally.

[0007] Furthermore, the outlet of the water pump is provided to extend horizontally through a connecting groove, and the end of the connecting groove extends upward to provide an outlet connector for connecting to the outlet pipe.

[0008] Furthermore, the water pump includes a mounting base, a motor, and an impeller. The mounting base is located at the top of the first water storage chamber, and the motor is located at the top of the mounting base. The mounting base has a connecting groove and a chamber for accommodating the impeller. One side of the chamber has an outlet that communicates with the connecting groove, and the impeller is connected to the output end of the motor.

[0009] Furthermore, the water drain body includes a second water storage chamber, a third water storage chamber, and a plurality of cooling pipes for refrigerant circulation. The first water storage chamber and the third water storage chamber are located at one end of the water drain body, and the second water storage chamber is located at the other end of the water drain body. The plurality of cooling pipes are divided into two groups, one group of cooling pipes is used to connect the first water storage chamber and the second water storage chamber, and the other group of cooling pipes is used to connect the second water storage chamber and the third water storage chamber.

[0010] Furthermore, the top of the third water storage chamber is provided with a water inlet connector, which is connected to the inner cavity of the third water storage chamber.

[0011] Furthermore, multiple cooling pipes are arranged in parallel at intervals, and heat dissipation fins are provided between adjacent cooling pipes.

[0012] Furthermore, the main body of the water drain is provided with a refrigerant filling interface.

[0013] Furthermore, the water drain body has fixed side plates on both sides, and the upper and lower edges of the fixed side plates extend into the inside of the water drain body and are provided with connecting ears.

[0014] Furthermore, the water drain body includes a fourth water storage chamber, and the inner cavity of the fourth water storage chamber is provided with a partition, which divides the fourth water storage chamber into the first water storage chamber and the third water storage chamber.

[0015] The beneficial effects of this utility model are as follows:

[0016] The water pump's inlet and outlet are perpendicular, which makes it easier to integrate with the main body of the water pump compared to the conventional structure with parallel inlets. It eliminates the need to separate multiple water storage chambers within the main body of the water pump to connect its inlet and outlet separately, reducing the need for partitions and effectively preventing cross-flow between water storage chambers.

[0017] Placing the water pump on the main body of the water drain not only makes its connection structure more stable, aesthetically pleasing, and space-saving, but also facilitates the installation of the main body of the water drain and the layout of water pipes. Attached Figure Description

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

The end of the water duct body 1 is provided with a first water storage chamber 2 for refrigerant circulation. A water pump is fixedly installed on the top of the first water storage chamber 2.

The end of the connecting groove 3 extends upward and is provided with a water outlet connector 4 for connecting to a water outlet pipe.

[0029] The water pump body 1 includes a second water storage chamber 5, a third water storage chamber 6, and multiple cooling pipes 7 for refrigerant circulation. The first water storage chamber 2 and the third water storage chamber 6 are located at one end of the water pump body 1, and the second water storage chamber 5 is located at the other end. The multiple cooling pipes 7 are divided into two groups, one group connecting the first water storage chamber 2 and the second water storage chamber 5, and the other group connecting the second water storage chamber 5 and the third water storage chamber 6. A water inlet connector 8 is provided at the top of the third water storage chamber 6, connecting to the inner cavity of the third water storage chamber 6. The multiple cooling pipes 7 are arranged in parallel at intervals, and heat dissipation fins 9 are provided between adjacent cooling pipes 7. The water pump body 1 is provided with a refrigerant charging port 10.

[0030] The water pump includes a mounting base 11, a motor 12, and an impeller 13. The mounting base 11 is located on top of the first water storage chamber 2, and the motor 12 is located on top of the mounting base 11. The mounting base 11 has a connecting groove 3 and a chamber for accommodating the impeller 13. One side of the chamber has an outlet communicating with the connecting groove 3. The impeller 13 is connected to the output end of the motor 12. The water pump body 1 has fixed side plates 14 on both sides. The upper and lower edges of the fixed side plates 14 extend inwards towards the water pump body 1 and are provided with connecting ears 15. The water pump body 1 can be installed on a computer chassis or server chassis through the connecting holes on the connecting ears 15. The water pump body 1 includes a fourth water storage chamber. The inner cavity of the fourth water storage chamber is provided with a partition 16, which divides the fourth water storage chamber into the first water storage chamber 2 and the third water storage chamber 6.

[0031] The working principle of this embodiment:

[0032] The heating element conducts heat to the water cooling head. The low-temperature refrigerant is heated to a high-temperature refrigerant after heat exchange in the water cooling head, and then enters the third water storage chamber 6 through the inlet pipe and inlet connector 8. When the water pump is working, the impeller 13 driven by the motor 12 rotates, which can draw the refrigerant from the first water storage chamber 2 into the chamber, and then pump it from the chamber to the connecting groove 3, and then flow out from the outlet connector 4. Driven by the water pump, the refrigerant enters the second water storage chamber 5 from the third water storage chamber 6 through the cooling pipe 7, and then enters the first water storage chamber 2 from the second water storage chamber 5 through the cooling pipe 7. The cooling pipe 7 can increase the heat dissipation area through the heat dissipation fins 9 and exchange heat with the surrounding environment. The high-temperature refrigerant is cooled to a low-temperature refrigerant after passing through the cooling pipe 7. This cycle of heat exchange continuously cools the heating element.
