[0029] This application proposes a liquid circulation recovery device. Refer to Figures 1 to 3 , this liquid circulation recovery device includes a container 10, on which a liquid outlet 11, a liquid return port 12 and an air hole are sequentially arranged from bottom to top; a pump body 21, which forms a circulation pipeline 20 with the container 10 and is used to pump the liquid out from the liquid outlet 11 and transport it to the liquid return port 12; a valve 22, which is arranged in the circulation pipeline 20 and is used to cut off the connection between the liquid return port 12 and the liquid outlet 11; and a gas supply assembly 30, which is connected to the circulation pipeline 20 and is used to supply gas to the section of the circulation pipeline 20 between the liquid return port 12 and the valve 22.

[0030] In this embodiment, the working port of the pump body 21 is communicated with the liquid inlet and the liquid outlet 11 respectively through pipelines. The water tank, the pump head and the pipelines outside the water tank form a circulating pipeline 20. The inside of the controller can be waterproofed so as to be communicated with the circulating pipeline 20, and the liquid in the circulating pipeline 20 can flow through the component to be tested (controller). Of course, the controller can also be isolated from the circulating pipeline 20. By setting a heat sink communicated with the circulating pipeline, the heat sink is placed in the controller to maintain the temperature stability in the controller. The air supply assembly 30 includes an air compressor and an air tank. The air compressor compresses air and inputs it into the air tank, and the air tank is communicated with the circulating pipeline 20 through an air valve. When it is necessary to quickly return the liquid in the circulating pipeline 20, the valve 22 can be closed, and air is supplied into the circulating pipeline 20. The high-pressure gas can drive the liquid to flow back into the container 10, so as to replace the new component to be tested subsequently. The whole reflux process does not require additional transfer, and the recovery efficiency is higher.

[0031] In some embodiments, referring to Figures 1 to 3 , the liquid circulation recovery device further includes a U-shaped pipe 13 inverted on the container 10, and one end of the U-shaped pipe 13 is communicated with the air hole. When the air supply assembly 30 supplies air into the circulating pipeline 20, due to the large air pressure, the too fast air flow rate will refine the liquid into small particles to form water mist, and the water diffused in the container 10 will escape from the air hole along with the air flow. The inverted U-shaped pipe 13 is provided to increase the escape path, so that the water mist condenses on the pipe wall and the escape amount is reduced. Of course, the U-shaped pipe 13 can be set as an S-shaped pipe to further increase the contact area between the water mist and the pipe wall. In addition, the liquid circulation recovery device further includes a water-gas separator arranged at the air hole, and the water-gas separator can be a filter screen, a steel wool or a sponge to intercept the water mist and reduce the escape amount of the circulating liquid. Further, leakage holes can be arranged at the upper part of the container 10, the U-shaped pipe 13 is arranged at the top of the container 10, and the leakage holes are arranged at intervals with the port of the U-shaped pipe 13 far from the air hole. The water mist escaping from the port of the U-shaped pipe 13 can also condense on the upper surface of the container 10 and flow back into the container 10 through the leakage holes.

[0032] Further, a collecting groove is recessed inwardly on the upper end surface of the container 10, the port of the U-shaped pipe 13 far from the air hole is located directly above the collecting groove, and the leakage holes are arranged in the collecting groove. The collecting groove is arranged in a square funnel shape. The water mist ejected from the port of the U-shaped pipe 13 is blocked by the collecting groove and condensed into liquid droplets, and the liquid droplets can flow along the inner bottom of the collecting groove and flow back into the container 10 through the leakage holes, so as to reduce the leakage amount of the liquid. In addition, the liquid circulation recovery device further includes a liquid adding pipe 14 arranged on the container 10 and communicated with the container 10, and a cover 15 is further arranged at the port of the liquid adding pipe 14. The liquid in the container 10 can be injected through the liquid adding pipe 14, and the cover 15 can prevent external dust and impurities from entering the container 10. At the same time, it can also prevent the water mist from spraying out from the liquid adding pipe 14. The pipe orifice of the liquid adding pipe 14 should be lower than the liquid return port 12, so that even if the liquid inside the container 10 is filled to the pipe orifice, it will not leak from the liquid return port 12.

[0033] Furthermore, the bottom of the container 10 is also provided with a drain port 16, and the drain port 16 is located below the liquid outlet 11. A rubber plug can be provided at the drain port 16 for blocking, and of course a drain valve can also be provided to close the drain port 16. When it is necessary to clean or replace the liquid inside the container 10, the drain valve can be opened to discharge the liquid. The drain port 16 is provided at the bottom of the container 10, which can reduce the residual amount of the liquid and drain it as much as possible. In addition, the liquid circulation recovery device also includes a bend pipe provided in the container 10, one end of the bend pipe is connected to the liquid return port 12, and the other end is provided toward the bottom of the container 10. When it is necessary to remove the residual liquid in the circulation pipeline 20, the compressed air can cause the liquid to turn when passing through the bend pipe, and the liquid and water mist will be discharged directly downward, reducing the diffusion amount inside the container 10. Of course, the end of the elbow can also be extended downward to a position below the mouth of the liquid adding pipe 14 so that the liquid level is above the elbow port. When the liquid in the circulation pipeline 20 is discharged, the water mist and air will first pass through the liquid to slow down the diffusion of the water mist.

[0034] In some embodiments, reference Figures 1 to 3 The liquid circulation recovery device further includes a support leg 17 disposed at the bottom of the container 10, and a groove is disposed at the end of the support leg 17 away from the container 10. The container 10 can be configured as a square box, and the support leg 17 is disposed near the four corners of the box, and the groove can be used to fix the container 10. In an actual working environment, the container 10 is often mounted on a rack and fixed by screws. The screws are clamped in the grooves and screwed on the rack. This fixing method has low cost and is convenient for disassembly and assembly.

[0035] This application also proposes a hot and cold integrated device, referring to Figures 1 to 3 The integrated hot and cold equipment includes the above-mentioned liquid circulation and recovery device, and a rack for installing the liquid circulation and recovery device. The integrated hot and cold equipment uses circulating liquid to perform heating and cooling and constant temperature tests on controllers, etc. After testing a controller, it is necessary to clean the circulating liquid in the pipeline and replace the next batch of objects to be tested. The valve 22 is arranged in the circulation pipeline 20, which is used to cut off the connection between the return liquid port 12 and the liquid outlet 11; the air supply component 30 is connected to the circulation pipeline 20, which is used to provide gas to the circulation pipeline 20, located between the return liquid port 12 and the valve 22. The gas supplied by the air supply component 30 to the circulation pipeline 20 can drive the liquid in the above section to flow back directly into the container 10 without transfer, and the recovery efficiency is higher. At the same time, the water mist generated by the high-pressure gas condenses in the collection tank and flows back to the inside of the container 10 through the leakage hole.

[0036] In the embodiment of the present application, the specific working principle of the liquid circulation recovery device is:

[0037] The liquid circulation recovery device includes a container 10, a pump body 21, a valve 22 and a gas supply assembly 30; an outlet 11, a return port 12 and an air hole are sequentially arranged on the container 10 from bottom to top; the pump body 21 and the container 10 form a circulation pipeline 20 for pumping the liquid from the outlet 11 and conveying it to the return port 12; the valve 22 is arranged in the circulation pipeline 20 for cutting off the connection between the return port 12 and the outlet 11; the gas supply assembly 30 is communicated with the circulation pipeline 20 for supplying gas to the section of the circulation pipeline 20 between the return port 12 and the valve 22. The gas supplied by the gas supply assembly 30 to the circulation pipeline 20 can drive the liquid in the above section to directly flow back into the container 10 without transfer, and the recovery efficiency is higher.
