[0026] like Figure 1 , Figure 2As shown in the figure, the liquid-cooled plate vacuum dryer provided by this utility model embodiment includes a vacuum pump 1, a vacuum tank 2, and a heater 3. A compressed air pipe (not shown in the figure) passes through the heater 3 and is connected to the liquid-cooled plate (not shown in the figure) to be dried through an exhaust pipe 4. The vacuum pump 1 is connected to the vacuum tank 2, and the vacuum tank 2 is connected to the liquid-cooled plate through a vacuum extraction pipe 5. Control valves 6 are provided on the compressed air pipe, the exhaust pipe 4, and the vacuum extraction pipe 5. Temperature and humidity sensors 7 are provided on the exhaust pipe 4 and the vacuum extraction pipe 5. A vacuum gauge 20 is also provided on the vacuum extraction pipe 5. The vacuum pump 1, the heater 3, the control valves 6, the vacuum gauge, and the temperature and humidity sensors 7 are all connected to a controller. The vacuum tank 2 and the heater 3 are set on the inner bottom plate of the cabinet 8. The controller and the control valves 6 are set on the brackets 9 on the upper part of the cabinet 8. The liquid-cooled plate is placed on the workbench 10 of the cabinet 8, and the vacuum pump 1 is set on the outside of the cabinet 8.

[0027] As a preferred structure, such as Figure 1 As shown, the cabinet 8 is L-shaped. A workbench 10 is located on the top of the lower cabinet of the cabinet 8, and liquid cooling plates can be placed on the workbench 10. A control panel 11 connected to a controller is located on the side of the upper cabinet of the cabinet 8, and the control panel 11 faces the workbench 10. Multiple workstations are arranged side-by-side on the workbench 10. Each workstation has a corresponding venting branch 40 and a vacuuming branch. The venting branches 40 of all workstations are connected in parallel to the venting pipes 4, and the vacuuming branches of all workstations are connected in parallel to the vacuuming pipes 5. Both the venting branches 40 and the vacuuming branches are located inside the cabinet 8 and are equipped with control valves 6. In this embodiment, six workstations are arranged side-by-side on the workbench. In actual operation, the liquid cooling plates can be fixed on a fixture, and six liquid cooling plates can be placed on the six workstations to dry them, thereby increasing production capacity.

[0028] exist Figure 2 In the illustrated embodiment, there are six heaters 3, corresponding to the six exhaust branches 40 for heating compressed air. A filter 23 is installed on the exhaust branch 40 before the compressed air enters the heater 3 to pre-filter the compressed air. A check valve 24 is installed at the inlet of the control valve 6 on the vacuum branch entering the liquid cooling plate, and a temperature and humidity sensor 7 is installed on the outlet pipe to facilitate online monitoring of temperature and humidity during the blowing and vacuuming processes.

[0029] In specific embodiments of this utility model, such as Figure 2As shown, a compressed air storage tank 12 is installed in the low cabinet below the workbench 10. Both ends of the compressed air storage tank 12 are connected to a compressed air pipe and an exhaust branch, respectively. The vacuum tank 2 is located inside the high cabinet. The interfaces 13 of the exhaust branch and the vacuum branch are both located on the upper side of the high cabinet above the workbench 10. The compressed air storage tank acts as a buffer, reducing fluctuations in compressed air caused by compressor malfunctions. To make efficient use of the internal space of the cabinet, horizontal and vertical partitions are installed at different locations on the support frame. These partitions isolate the compressed air storage tank from the heater and vacuum tank, while also providing support for the exhaust pipe and vacuum branch.

[0030] In actual manufacturing, the interfaces 13 of the venting branch and the vacuum branch are respectively connected to the liquid cooling plate through connecting pipes with quick-connect fittings (not shown in the figure). Using connecting pipes with quick-connect fittings allows for quick connection to the inlet and outlet of the liquid cooling plate using different connecting pipes, realizing the alternation between venting and vacuuming states, as well as the replacement of different liquid cooling plates.

[0031] In specific embodiments of this utility model, such as Figure 1 , Figure 3 As shown, a keyboard 14 connected to a control panel 11 is located below the workbench 10. Both the keyboard 14 and mouse 21 are housed in drawers 15. An opening for the drawers 15 is provided on the side of the cabinet 8. Control buttons 16 are located on the edge of the workbench 10 and on both sides of the drawers 15. In this embodiment, six sets of control buttons are designed, with two buttons in each set, used to control the start and stop of the six workstations. Specifically, a tray 17 for supporting the drawers 15 is provided inside the cabinet 8 below the workbench 10. Handles 18 are provided on the outer side of the drawers 15, and slide rails that slide against the bottom of the drawers 15 are provided on both sides of the top surface of the tray 17.

[0032] To facilitate moving the equipment to different work locations, the bottom of the cabinet 1 is equipped with casters 19, which are universal casters with brakes.

[0033] To further optimize the above scheme, the drain pipe connected to the liquid cooling plate outlet can extend into the recovery tank 22 inside the cabinet 8 for recovering the discharged waste liquid. During installation, a connecting hose can be used to connect the liquid cooling plate outlet to one port of the control valve on the vacuum line, and then the drain pipe is installed on the other port of the control valve, extending into the recovery tank. The control valve on the vacuum line is a three-way reversing valve. Vacuuming is performed through one port with a check valve, at which point the port connected to the drain pipe is closed. During venting, the other two ports of the control valve are connected to the liquid cooling plate and the drain pipe, allowing the blown-out wastewater to be discharged into the recovery tank.

[0034] The specific application process of this utility model is as follows: The air blowing and evacuation time and the vacuuming time are preset on the control panel. The controller automatically starts the control valve on the evacuation pipeline and simultaneously starts the heater to heat the compressed air. The temperature sensor detects that the temperature has risen to a certain level (depending on the drying requirements of the liquid-cooled plates). The heated compressed air enters multiple liquid-cooled plates simultaneously through the evacuation pipeline and multiple evacuation branches, vaporizing and expelling the water droplets inside, thus initially achieving the evacuation process. After the evacuation process is completed, the controller automatically closes the control valve on the evacuation pipeline and opens the control valve on the vacuuming pipeline, starting the vacuum pump to evacuate the vacuum tank. Then, the vacuum tank simultaneously evacuates multiple liquid-cooled plates through the vacuuming pipeline and multiple vacuuming branches. A vacuum gauge and a humidity sensor simultaneously detect this. When the humidity drops to a certain range, the drying process is complete.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
