Description

Technical Field

[0001] The present application relates to the field of cooling process technology, and in particular to a closed cooling cycle device. Background Art

[0002] In the copper foil manufacturing industry, many processes will generate a large amount of heat energy. In order to ensure the normal progress of the process, a set of cooling equipment is required for cooling the process. The cooling process mainly relies on cooling towers to cool the cooling water.

However, in areas with low environmental humidity, the water temperature is high after circulation, and it evaporates too quickly, which will cause a large amount of water loss; and open cooling towers will cause wind and sand to enter the cooling water. Long-term operation will cause the sediment in the cooling water to gradually increase, and eventually lead to pipe blockage.

[0025] In the copper foil manufacturing industry, many processes will generate a large amount of heat energy. In order to ensure the normal progress of the process, a set of cooling equipment is required for cooling the process. The cooling process mainly relies on cooling towers to cool the cooling water. The most common cooling tower is an open cooling tower, which reduces the water temperature by contact between water and air. However, in areas with low environmental humidity, the water temperature is high after circulation, and it evaporates too quickly, which will cause a large amount of water loss; and open cooling towers will cause wind and sand to enter the cooling water. Long-term operation will cause the sediment in the cooling water to gradually increase, and eventually lead to pipe blockage. In summary, how to solve the problem of large water loss and wind and sand mixing caused by open cooling towers is a technical problem that needs to be solved in this field.

[0026] In view of this, the present application provides a closed cooling circulation device that can avoid the problems of large water loss and wind and sand mixing caused by an open cooling tower.

[0027] An exemplary closed cooling cycle apparatus is as follows:

[0028] Figure 1 Shown is a schematic structural diagram of a closed cooling cycle device provided in one embodiment of the present application. Figure 2 FIG. 1 is a partial structural schematic diagram of a closed cooling cycle device provided by another embodiment of the present application. The present application provides a closed cooling cycle device. In one embodiment, as Figure 1As shown, the closed cooling circulation device includes: a water storage tank 1, a cooling tower 4, a cooling mechanism, a heat-using device 7 and a water pumping mechanism. The water storage tank 1 is used to store cooling water. The cooling tower 4 includes a cooling cavity, and the cooling cavity includes a first water inlet 102 and a first water outlet 103, and the first water inlet 102 is connected to the water storage tank 1. Specifically, the cooling cavity is closed and has only two openings: a first water inlet 102 and a first water outlet 103. The cooling mechanism is arranged in the cooling tower 4, and the cooling mechanism exchanges heat with the cooling cavity to cool down the cooling water in the cooling cavity. The heat-using device 7 includes a heating mechanism and a heat exchange mechanism, and the heat exchange mechanism is used to cool down the heating mechanism. The heat exchange mechanism includes a second water inlet and a second water outlet, and the second water inlet is connected to the first water outlet 103, and the second water outlet is connected to the water storage tank 1. The water pumping mechanism is configured to drive the cooling water to circulate between the water storage tank 1, the cooling mechanism and the heat exchange mechanism.

[0029] When this embodiment is used, the entire device is closed, and the cooling mechanism does not cause a large amount of evaporation loss of cooling water when cooling the cooling water in the cooling cavity of the cooling tower. In addition, the closed structure can prevent debris, mud and sand from entering the circulation device and causing blockage.

[0030] In one embodiment, if Figure 1 As shown, the water storage tank 1 is connected to the first water inlet 102 via a first water pipe. The water pumping mechanism comprises a first pump 2, which is connected to the first water pipe and is used to pump the cooling water in the water storage tank 1 to the cooling mechanism.

[0031] In one embodiment, if Figure 1 As shown, the closed cooling cycle device also includes a first exhaust member 3, which is arranged on the first water pipe. The first exhaust member 3 can exhaust a certain amount of gas, thereby balancing the air pressure difference between the water storage tank 1 and the cooling mechanism to prevent the air pressure in the water storage tank 1 and / or the cooling mechanism from being too high. Specifically, an exhaust hole can be opened on the first water pipe to form the first exhaust member 3.

[0032] In one embodiment, the first water outlet 103 and the second water inlet are connected by a second water pipe, and the water pumping mechanism includes a second pump 5, which is connected to the second water pipe. The second pump 5 is used to pump the cooling water in the cooling mechanism to the heat-using equipment 7.

[0033] In one embodiment, the closed cooling cycle device further includes a second exhaust member 6, which is disposed on the second water pipe. The second exhaust member 6 can exhaust a certain amount of gas, thereby balancing the air pressure difference between the cooling mechanism and the heat-using device 7, so as to prevent the air pressure in the cooling mechanism and / or the heat-using device 7 from being too high. Specifically, an exhaust hole can be provided on the second water pipe to form the second exhaust member 6.

[0034] Specifically, the heat-using device 7 is a device that generates a large amount of heat energy in the process flow, and the heat-using device 7 dissipates heat through a heat-generating mechanism, and the heat-generating mechanism is specifically, for example, a heat sink. The heat exchange mechanism in the heat-using device 7 absorbs the heat of the heat-generating mechanism through contact heat exchange, thereby achieving a cooling operation of the heat-using device 7.

[0035] In one embodiment, if Figure 1 As shown, the closed cooling circulation device further includes a check valve 8, which is arranged on the second water pipe. The check valve 8 can prevent the cooling water from flowing back to the cooling tower 4, thereby ensuring the unidirectional circulation of the cooling water.

[0036] In one embodiment, the second water outlet and the water storage tank 1 are connected via a third water pipe, and the closed cooling circulation device further comprises a temperature measuring mechanism 9, which is arranged on the third water pipe and is used to detect the water temperature of the cooling water after heat exchange in the third water pipe. The temperature of the cooling water can be accurately known through the temperature measuring mechanism 9 to implement different strategies. For example, when the temperature of the cooling water is too high, the flow rate of the water pump mechanism is increased to increase the circulation speed, so as to cool down faster.

[0037] In one embodiment, if Figure 1 As shown, the closed cooling cycle device further includes a third exhaust member 10, which is disposed on the third water pipe. The third exhaust member 10 can exhaust a certain amount of gas, thereby balancing the air pressure difference between the heat-using device 7 and the water storage tank 1, so as to prevent the air pressure in the heat-using device 7 and / or the water storage tank 1 from being too high. Specifically, an exhaust hole can be opened on the third water pipe to form the third exhaust member 10.

[0038] In one embodiment, if Figure 1 As shown, the cooling mechanism includes a cooling fan 11, and the cooling fan 11 blows air toward the cooling cavity.

[0039] In one embodiment, if Figure 2 As shown, the cooling cavity includes: a water tank 101, a top baffle 104 and a bottom baffle 105. The first water outlet 103 is arranged at the bottom of the water tank 101, and the horizontal height of the first water inlet 102 is higher than the horizontal height of the first water outlet 103. The top baffle 104 is arranged on the top inside the water tank 101. The bottom baffle 105 is arranged on the bottom inside the water tank 101, and the bottom baffle 105 and the top baffle 104 are arranged alternately. In this embodiment, the cooling water entering the water tank 101 through the first water inlet 102 sequentially bypasses the top baffle 104 and the bottom baffle 105 which are arranged alternately, which can increase the flow distance of the cooling water in the cooling cavity, thereby improving the cooling efficiency of the cooling fan 11 on the cooling water in the cooling cavity, and the cooling water is discharged from the first water outlet 103 after passing through the water tank 101.
