[0014] Beneficial effects of the present invention: 1. During the test, the device uses a water removal module to effectively remove the water mist on the surface of the top liquid cooling plate to prevent the water mist from condensing into water droplets, thereby protecting the safety of the internal circuit of the device. Specifically, when the motor starts and runs, it drives the reciprocating screw to rotate, thereby pushing the moving seat to reciprocate along the fixed frame. As the moving seat moves, the fixed plate moves accordingly, and the movable plate is driven to move accordingly through the connecting piece. The reciprocating movement of the movable plate above the top liquid cooling plate enables the water absorption layer on it to effectively wipe and absorb the moisture formed on the surface of the top liquid cooling plate. The main benefit of this water removal mechanism is that it can significantly reduce the potential damage of water droplets to the circuit, ensuring the safety and stability of equipment operation; 2. When the movable plate moves to the top of a water storage box, it will contact the inclined surface on the guide block and move down along the inclined surface. During the downward movement, the water absorption layer contacts and is squeezed with the partition, and the water inside the water absorption layer is squeezed out and flows into the water storage box through the through hole. The main benefit of this design is to ensure the water absorption performance of the water absorption layer, thereby improving its effect of removing water from the surface of the top liquid cooling plate. In addition, when the magnetic block fixed on the movable plate generates attraction between the partition, the movable plate can be closely attached to the water absorption layer, thereby enhancing the water squeezing effect; 3. The feedback structure design in the water storage box can effectively monitor and judge the water storage amount in the water storage box. This mechanism provides great convenience for the operation and maintenance of the equipment. Specifically, when the water level in the water storage box rises, the float will move upward and push the feedback rod to move. The feedback rod extends to a structure with an opening, so that the staff can intuitively observe the position of the feedback rod and judge the water volume in the water storage box. The feedback structure provides real-time water level monitoring, and the staff can timely understand the changes in the water volume in the water storage box to avoid overflow or equipment damage due to excessive water level.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-7 As shown, a cold plate type liquid cooling load device comprises: a device housing 1; a plurality of test modules, all of which are arranged inside the device housing 1, each test module comprises two liquid cooling plates 2 and a heating plate 3, the heating plate 3 is placed between the two liquid cooling plates 2, the device housing 1 adopts a chassis-type design, which is both practical and intuitive, and its front side features are remarkable, and is equipped with a push-pull handle for easy operation, and integrates three independent modules, each module is equipped with an upper power supply power display screen and a lower temperature display screen, a total of six display screens, which are used to monitor the operating status of each module in real time, in addition, there are also hot and cold liquid cooling pipeline ports on the front side, including one inlet and one outlet, a total of six quick-connect ports, which effectively support an efficient liquid cooling heat dissipation system, and a push-pull handle is also provided on the back side for easy movement or maintenance, and three 200-240V power connectors are equipped to meet the power requirements of each module, in particular, there is also a power connector with an input of 200-240V and an output of low-voltage 12V DC, which is specially used for supplying power to the temperature display screen group. The device has a unique internal structure, and its core components include semiconductor heating plates and aluminum water-cooling plates. The semiconductor heating plates are designed to simulate the high heat and power consumption scenarios of CPU / GPU in high-power servers. The upper and lower sides of each heating plate are tightly fitted with the aluminum water-cooling plate to form an effective heat conduction path. When the semiconductor heating plate is powered on and heated, the liquid cooling system starts to circulate: the low-temperature coolant is introduced into the aluminum water-cooling plate at the liquid inlet, and the heat generated by the semiconductor heating plate is efficiently absorbed and taken away by the flow of the coolant. Subsequently, the high-temperature coolant that has absorbed the heat flows out of the aluminum water-cooling plate from the outlet and is guided to the outside of the device for further processing or cooling. This cycle can not only simulate the working conditions of the cold plate liquid cooling system, but also can be used to test and demonstrate the performance of the system in actual applications. When the cold plate type liquid cooling load device proposed in the present invention is in use, the test module is mainly composed of a semiconductor heating plate (i.e., the heating plate 3) and an aluminum water cooling plate (i.e., the liquid cooling plate 2). The semiconductor heating plate is used to simulate the heat power consumption of the CPU / GPU of a high-power server. An aluminum water cooling plate is closely attached to the upper and lower parts of each heating plate. When the semiconductor heating plate is powered and generates heat, the liquid inlet and outlet circulation is realized through the liquid cooling system. The low-temperature coolant flows into the aluminum water cooling plate and is in close contact with the heating plate to absorb the heat generated by it, thereby reducing the temperature of the heating plate. Subsequently, the high-temperature coolant flows out of the water cooling plate and is connected to the outside of the device. Through this circulation process, the coolant effectively takes away the heat of the heating plate and maintains the normal operating temperature of the device. This design can not only simulate and test the thermal management effect of high-power equipment in operation, but also demonstrate the overall working condition of the cold plate type liquid cooling system. Several water removal modules are arranged inside the equipment housing 1. Several water removal modules are respectively arranged opposite to several liquid cooling plates 2 located at the top. Each water removal module includes a driving structure, a water absorption structure, two control structures and two water storage structures. The driving structure is located above the top liquid cooling plate 2. The water absorption structure is arranged between the driving structure and the top liquid cooling plate 2.

The water absorption structure includes: a fixed plate 51, fixed to the bottom surface of the moving seat 44; two connecting members 52, respectively arranged at the two ends of the bottom surface of the fixed plate 51, the connecting member 52 includes an outer cylinder, an inner rod and a spring, the outer cylinder is fixed to the bottom surface of the fixed plate 51, the inner rod is slidably arranged in the outer cylinder, the bottom end of the inner rod extends to the outside of the outer cylinder, and is connected to the movable plate 53 is fixedly connected, one end of the spring is connected to the outer cylinder, and the other end is connected to the inner rod; the movable plate 53 is placed below the fixed plate 51 and connected to the two connecting pieces 52; the water absorption layer 54 is arranged on the bottom surface of the movable plate 53 and contacts with the liquid cooling plate 2 at the top, the water absorption layer 54 is made of sponge, and the length of the water absorption layer 54 is greater than the width of the liquid cooling plate 2; the magnetic block 55 is fixed on the movable plate 53, and the control structure includes: a side plate 71, fixed on one end of the fixed frame 41; a guide block 72, fixed on the end of the side plate 71 away from the fixed frame 41, an inclined surface is arranged on the guide block 72, and the guide block 72 is arranged opposite to the movable plate 53, and the inclined directions of the inclined surfaces of the two guide blocks 72 are opposite; During the test, the device can use the water removal module to remove the water mist on the surface of the top liquid cooling plate 2 to prevent the water mist from condensing into water droplets, thereby preventing the water droplets from damaging the circuit safety inside the device. Specifically, the motor 42 is started, and the motor 42 can drive the reciprocating screw 43 to rotate when it is running. When the reciprocating screw 43 rotates, it can drive the moving seat 44 to reciprocate along the fixed frame 41. When the moving seat 44 moves, the fixed plate 51 will move accordingly. The fixed plate 51 can also drive the movable plate 53 to move through the two connecting members 52, so that the movable plate 53 reciprocates above the top liquid cooling plate 2. During the reciprocating movement of the movable plate 53, the water absorption layer 54 thereon can wipe the surface of the top liquid cooling plate 2, thereby absorbing the moisture formed on the surface of the top liquid cooling plate 2, and playing a role in removing water from the top liquid cooling plate 2; The water storage structure includes: a water storage box 61, which is placed on one side of the test module and has an open top; a partition 62, which is fixed to the inner top of the water storage box 61 and is made of magnetic material; and a plurality of through holes 63, which are all opened on the partition 62; During the reciprocating movement of the movable plate 53, when the movable plate 53 moves to the top of one of the water storage boxes 61, the movable plate 53 will contact the inclined surface on one of the guide blocks 72 and move downward along the inclined surface. When the movable plate 53 moves downward, the water absorbing layer 54 will contact the partition 62 and be squeezed between the partition 62. When the water absorbing layer 54 is squeezed, the water inside the water absorbing layer 54 will be squeezed out, and the squeezed water will flow into the water storage box 61 through a plurality of through holes 63. This design can be used to absorb the water inside the water absorbing layer 54.

In addition, a magnetic block 55 is fixed on the movable plate 53. When the movable plate 53 moves to a position facing the partition 62, the magnetic block 55 will be attracted to the partition 62 made of magnetic material under the action of magnetic attraction, which makes the magnetic block 55 have a tendency to approach the partition 62. Under the action of the magnetic block 62, the movable plate 53 can press the water absorption layer 54 tightly, thereby ensuring the water squeezing effect on the water absorption layer 54. The movable plate 53 is connected to the fixed plate 51 through two connecting members 52. The setting of the connecting members 52 enables the movable plate 53 to move relative to the fixed plate 51. During the movement of the movable plate 53, the outer cylinder and the inner rod play a role in limiting and guiding the movement of the movable plate 53. In addition, when the movable plate 53 is offset from the water storage box 61, the spring between the outer cylinder and the inner rod is used to automatically reset the movable plate 53. Each water storage box 61 is provided with a feedback structure, and the feedback structure includes: a float 81, which is placed inside the water storage box 61; a feedback rod 82, one end of which is fixedly connected to the float 81, and the other end extends to the outside of the water storage box 61, the feedback rod 82 passes through the partition 62 and is slidably connected to the partition 62; an opening 83 is opened on the side of the equipment housing 1, and the end of the feedback plate 82 away from the float 81 extends into the opening 83. A feedback structure is also provided in the water storage box 61. The staff can judge the water storage amount in the water storage box 61 through the feedback structure, so as to timely deal with the water collected in the water storage box 61. Specifically, when the water level in the water storage box 61 rises, the float 81 will move upward with the water level. When the float 81 moves, the feedback rod 82 will also move accordingly. An opening 83 is opened on the side of the equipment housing 1, and the feedback rod 82 extends into the opening 83. Therefore, the staff can judge the water amount in the water storage box 61 through the position of the feedback rod 82.
