Description

Technical Field

[0001] The utility model relates to the technical field of circulating cooling devices, in particular to a cooling water recovery structure of a circulating cooling device. Background Art

[0002] During the cooling water circulation process, dissolved salts, minerals, and microorganisms in the water will gradually accumulate due to evaporation, concentration, and corrosion of equipment materials, leading to deterioration of water quality. High concentrations of dissolved salts are easily deposited on the surfaces of equipment such as pipes, heat exchangers, and cooling heads, forming hard scale that is difficult to remove. These scale layers not only increase water flow resistance and reduce heat exchange efficiency, but may also cause local overheating and accelerate equipment corrosion and aging.

[0003] Currently, there is no need to replace the cooling water in the circulating cooling device in the existing technology. Usually, the technology of the previous circulating cooling device was not very good, and during use, there was often a concern that gaps in the circulating cooling device would cause cooling water leakage. Now that the manufacturing technology has been greatly improved, the circulating cooling device is no longer easily damaged. However, if the cooling water is used in the circulating cooling device for a long time, the cooling water will face failure and the cooling effect will deteriorate. It is very necessary to replace the cooling water in time. Utility Model Content

[0006] Preferably, the cooling water flowing in the cold head and the heat dissipating fin 1 dissipate heat to the heating plate, and the heat in the cooling module is cooled by the heat dissipating fin 2, cooling water and the heat dissipating fan. The cold head, cooling module, circulation pipe 1 and circulation pipe 2 can form a circulation cooling device. The connecting pipe 2, valve, tee pipe and connecting pipe 4 at the bottom of circulation pipe 2 form a recovery pipeline for the old coolant. The connecting pipe 1 and valve at the top of circulation pipe 1 compensate for the air pressure in the circulation cooling device when recovering the old coolant.

[0007] Preferably, the pipeline also includes connecting pipe 2, a valve, connecting pipe 3 above the tee, and connecting pipe 4 below the tee. By setting a valve between connecting pipe 2 and connecting pipe 3, the coolant circulating in the circulating cooling device is prevented from entering connecting pipe 3, affecting the cooling efficiency of the heating plate. When the recycling box is not working, the recycling box is removed and a corresponding plug is installed at the bottom of connecting pipe 4.

[0008] Preferably, one side of the tee is connected to connecting pipe three, one side is connected to connecting pipe four, and the other side is connected to connecting pipe five. The side of connecting pipe five away from the tee is connected to a valve, connecting pipe six, and a replenishing tank.

[0010] Preferably, the replenishing box further comprises a replenishing push rod, which squeezes the new coolant in the holding tank through the replenishing push rod, serving as a way for the new coolant to enter the circulating cooling device.

[0011] Preferably, the supplementary push rod includes a push plate and a vertical rod corresponding to the holding tank. A support rod is provided at one end of the vertical rod away from the push plate. The support rod includes a threaded hole. The push plate contacts the new coolant in the holding tank. The push plate corresponds to the holding tank, thereby improving the efficiency of the new coolant entering the circulating cooling device.

[0012] Preferably, the outer shell of the replenishing box is fitted with a motor, which includes an output shaft. The output shaft sleeve is provided with a screw rod corresponding to the threaded hole. The motor drives the screw rod to control the pushing speed of the replenishing push rod, which can accurately calculate how much new coolant flows out of the storage tank.

[0013] The beneficial effects of the present invention are as follows: compared with the circulating cooling device in the prior art, which does not have a structure for replacing cooling water, the cooling water flowing in the cold head and the heat dissipation fin 1 are used to dissipate heat to the heating plate, and the heat in the cooling module is cooled by the heat dissipation fin 2, cooling water and the heat dissipation fan. The cold head, cooling module, circulating pipe 1 and circulating pipe 2 can form a circulating cooling device. The connecting pipe 2, valve, tee pipe and connecting pipe 4 at the bottom of the circulating pipe 2 form a recovery pipeline for the old coolant. The connecting pipe 1 and the valve at the top of the circulating pipe 1 compensate for the air pressure in the circulating cooling device when recovering the old coolant.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1-4In this embodiment, the heat is dissipated to the heating plate 1 by the cooling water flowing in the cold head 2 and the heat dissipation fin 1 21, and the heat in the cooling module 3 is cooled by the heat dissipation fin 2 31, the cooling water and the heat dissipation fan 4. The cold head 2, the cooling module 3, the circulation pipe 1 51, and the circulation pipe 2 52 can form a circulation cooling device. The connecting pipe 2 722, the valve 71, the three-way pipe 73, and the connecting pipe 4 724 at the bottom of the circulation pipe 2 52 form a recovery pipeline for the old coolant. The connecting pipe 1 721 and the valve 71 at the top of the circulation pipe 1 51 compensate for the air pressure in the circulation cooling device when recycling the old coolant. The pipeline also includes the connecting pipe 2 722, the valve 71, the connecting pipe 3 723 above the three-way pipe 73, and the connecting pipe 2 722, the valve 71, the connecting pipe 3 723 below the three-way pipe 73. The connecting pipe four 724 is provided with a valve 71 between the connecting pipe two 722 and the connecting pipe three 723 to prevent the coolant circulating in the circulating cooling device from entering the connecting pipe three 723 and affecting the cooling efficiency of the heating plate 1. When the recovery box 62 is not working, the recovery box 62 is removed and a corresponding plug is installed at the bottom of the connecting pipe four 724. One side of the three-way pipe 73 is connected to the connecting pipe three 723, one side is connected to the connecting pipe four 724, and the other side is connected to the connecting pipe five 725. The side of the connecting pipe five 725 away from the three-way pipe 73 is connected to the valve 71, the connecting pipe six 74, and the replenishing box 61. The new coolant in the replenishing box 61 is isolated by the valve 71 on the right side of the connecting pipe five 725.

[0023] See also Figure 2-Figure 5 In this embodiment, the replenishing box 61 includes a holding tank 611, which can hold new cooling water. By pouring new coolant into the holding tank 611, it is convenient to let the new coolant enter the circulating cooling device. The replenishing box 61 also includes a replenishing push rod 63, which squeezes the new coolant in the holding tank 611 as a way for the new coolant to enter the circulating cooling device. The replenishing push rod 63 includes a push plate 632 corresponding to the holding tank 611 and a vertical rod 631. The vertical rod 631 is away from the push plate 632. A support rod 633 is provided at the end, and the support rod 633 includes a threaded hole 634, which contacts the new coolant in the receiving tank 611 through a push plate 632. The push plate 632 corresponds to the receiving tank 611, which improves the efficiency of the new coolant entering the circulating cooling device. The outer shell of the replenishing box 61 is attached to a motor 65, and the motor 65 includes an output shaft. The output shaft sleeve is provided with a screw rod 64 corresponding to the threaded hole 634. The screw rod 64 is driven by the motor 65 to control the pushing speed of the replenishing push rod 63, which can accurately calculate the amount of new coolant flowing out of the receiving tank 611.

[0024] During operation, the cold head 2, circulation pipe 1 51, cooling fan 4, and circulation pipe 2 52 constitute a circulation cooling device. The cooling water in the circulation cooling device is driven by the water circulation device 32 to realize internal circulation. The water circulation device 32 here is a waterproof driving device installed in the cooling module 3. The water circulation device 32 is a prior art and its working principle is not repeated here. The heat of the heating plate 1 is taken away by the circulation cooling device. When the cooling water in the circulation cooling device needs to be recovered, the operator can open the valve 71 on the connecting pipe 1 721 to connect the inside of the circulation cooling device with the outside atmosphere, and then remove the plug at the bottom of the connecting pipe 4 724 and install the recovery box 62. Here, make sure that the valve 71 on the right side of the connecting pipe 5 725 is locked, and finally open the valve 71 on the connecting pipe 3 723. At this time, the cooling water in the circulation cooling device is released into the recovery box 62. The old cooling water in the recovery box 62 cannot be poured out at will to avoid affecting the environment. When the old cooling water in the circulating cooling device is recovered, the recovery tank 62 filled with the old cooling water is removed and properly disposed of, and the plug is reinstalled at the bottom of the connecting pipe 724. At this time, the driving motor 65 rotates to completely separate the replenishing push rod 63 from the screw rod 64, and the replenishing push rod 63 is taken out of the holding tank 611, and new cooling water is poured into the holding tank 611. Then, the threaded hole 634 at the support rod 633 is aligned with the screw rod 64, and the driving motor 65 rotates, and the replenishing push rod 63 is moved to the The downward movement presses the coolant in the storage tank 611. At this time, the valve 71 on the left side of the connecting pipe 6 74 and the valve 71 above the connecting pipe 3 723 are opened. The replenishing push rod 63 presses the new coolant in the storage tank 611 to enter the circulating cooling device. When a proper amount of coolant emerges from the valve 71 above the connecting pipe 1 721, it means that the filling is completed. Then close the valve 71 above the connecting pipe 1 721. The motor 65 here is glued to the replenishing box 61 to avoid drilling the replenishing box 61.

[0025] Through the above steps, the cooling water flowing in the cold head 2 and the heat dissipation fin 1 21 dissipate heat to the heating plate 1, and the heat in the cooling module 3 is cooled by the heat dissipation fin 2 31, the cooling water and the heat dissipation fan 4. The cold head 2, the cooling module 3, the circulation pipe 1 51 and the circulation pipe 2 52 can form a circulation cooling device. The connecting pipe 2 722, the valve 71, the three-way pipe 73 and the connecting pipe 4 724 at the bottom of the circulation pipe 2 52 form a recovery pipeline for the old coolant. The connecting pipe 1 721 and the valve 71 at the top of the circulation pipe 1 51 compensate for the air pressure in the circulation cooling device when recycling the old coolant, so as to solve the problem that the cooling water will become ineffective and the cooling effect will deteriorate due to long-term use in the circulation cooling device.
