An embodiment of the present application provides a water chilling apparatus 100, as shown in fig. 1 to 3, including a water pipe 110, a first heat exchange pipe 121, and a second heat exchange pipe 122. The water pipe 110 includes a first water pipe 111 and a second water pipe 112, the first water pipe 111 and the second water pipe 112 are communicated, and water flows in from the first water pipe 111 and flows out through the second water pipe 112. The first heat exchange tube 121 and the first water tube 111 are attached to each other, a condensing agent flows into the first heat exchange tube 121, the condensing agent absorbs heat, the first heat exchange tube 121 and the first water tube 111 are fully contacted and directly exchange heat, and water flow in the first water tube 111 can be rapidly cooled. The second heat exchange tube 122 and the second water tube 112 are disposed at an interval, and a cold storage medium is disposed between the second heat exchange tube 122 and the second water tube 112. The condensing agent flows into the second heat exchanging pipe 122, absorbs heat, reduces the temperature of the cold storage medium, and reduces the temperature of the water flow in the second water pipe 112, so that the second heat exchanging pipe 122 exchanges heat with the second water pipe 112 through the cold storage medium.
With the above structure, the cooling water device 100 of the embodiment of the present application includes two heat exchange structures, the first heat exchange tube 121 is arranged to directly contact with the first water tube 111 for heat exchange, and the second heat exchange tube 122 is arranged to indirectly exchange heat with the second water tube 112 through a cold storage medium. When the temperature of the inflow water flow is higher, the first heat exchange tube 121 and the first water tube 111 are fully utilized to directly contact for heat exchange, the heat exchange amount is large, the heat exchange amount efficiency is high, the inflow water is rapidly reduced to a certain temperature, and the cooling effect is realized. When the temperature of the inflow water flow is low, the temperature of the cold accumulation medium is reduced by the second heat exchange tube 122, and the temperature of the water flow in the second water tube 112 is reduced by the cold accumulation medium with controllable cold amount, so that the temperature of the water flow in the second water tube 112 is fully reduced, meanwhile, the water flow in the second water tube 112 is prevented from reaching the freezing temperature, and the ice blockage phenomenon in the second water tube 112 is avoided. This application embodiment is through setting up two kinds of heat transfer modes of direct contact heat transfer and the indirect heat transfer of cold-storage, can fully reduce the temperature of intaking to prevent the phenomenon that water pipe 110 is iced stifled, effectively guarantee cooling water device 100 promptly and cool the effect promptly, promote user experience.
Specifically, as shown in fig. 1 and 2, the first heat exchange tubes 121 extend side by side along the extending direction of the first water tubes 111 to fully contact with the first water tubes 111, and the first heat exchange tubes 121 can fully absorb heat of water flow in the first water tubes 111, reduce the temperature of the water flow in the first water tubes 111, and effectively ensure the cooling effect of the instant cooling device on the water flow. Similarly, as shown in fig. 3, the second heat exchanging tube 122 is disposed in parallel with the second water tube 112 at an interval, so that the second heat exchanging tube 122 can fully absorb heat of water flow in the second water tube 112 through the cold storage medium, thereby reducing the temperature of water flow in the second water tube 112, and effectively ensuring the cooling effect of the cooling device on water flow.
Further, in some embodiments, the water cooling device 100 further includes a first sensor (not shown in the figure), which is disposed at the water inlet end of the first water pipe 111 to monitor the water inlet temperature, so as to select different heat exchange cooling manners according to the temperature of the water inlet flow.
In order to fully utilize the cold energy of the condensing agent and prevent the inlet water from being frozen due to rapid temperature reduction, as shown in fig. 1 and 2, the outlet end of the first heat exchange pipe 121 is communicated with the inlet end of the second heat exchange pipe 122. The condensing agent flowing through the first heat exchanging pipe 121 sufficiently absorbs heat of the water flow in the first water pipe 111 to rapidly lower the water flow in the first water pipe 111 to a certain temperature, but the water in the first water pipe 111 does not reach freezing temperature. The refrigerant then flows to the second heat exchange tubes 122, the temperature of the refrigerant still being lower than the temperature of the cold storage medium. By communicating the outlet end of the first heat exchange tube 121 with the inlet end of the second heat exchange tube 122, the condensing agent can be fully utilized, and the water flow in the water tube 110 can be subjected to two-stage cooling process, so that the water temperature can be fully reduced and ice blockage can be prevented.
In addition, since the inflow water flows through the first water pipe 111 and then flows through the second water pipe 112, when the cooling water device 100 is just started, the cooling capacity of the condensing agents in the first heat exchange pipe 121 and the second heat exchange pipe 122 is low, at this time, the inflow water flows through the first water pipe 111 to directly exchange heat with the first heat exchange pipe 121, and when the cooling capacity is increased, the cooled inflow water in the first water pipe 111 flows to the second water pipe 112, so that the first water pipe 111 can be prevented from being blocked by ice due to the first heat exchange pipe 121 after the cooling capacity is increased.
In some embodiments, namely, the cold water device 100 further comprises a liquid inlet pipe 130 and a three-way valve 131, the liquid inlet pipe 130 connects the inlet end of the first heat exchange pipe 121 and the inlet end of the second heat exchange pipe 122, and the three-way valve 131 is disposed at the connection between the liquid inlet pipe 130 and the first heat exchange pipe 121 and the second heat exchange pipe 122. So that the refrigerant flowing from the liquid inlet pipe 130 can be selectively introduced into one or both of the first and second heat exchanging pipes 121 and 122 by the adjustment of the three-way valve 131. According to the temperature of the inlet water and the temperature of the cold water after the temperature reduction, the first heat exchange tube 121 can be selected to be directly contacted for rapid temperature reduction, or the second heat exchange tube 122 can be indirectly cooled through a cold storage medium, so that the water tube 110 is prevented from being blocked by ice.
It should be noted that, as shown in fig. 1 and 2, the inlet end communication of the liquid inlet pipe 130 and the first and second heat exchange pipes 121 and 122 may be indirect communication, that is, the liquid inlet pipe 130 communicates with the first and second adapter pipes 1211 and 1221 through the three-way valve 131, the first adapter pipe 1211 communicates with the inlet end of the first heat exchange pipe 121, and the second adapter pipe 1221 communicates with the inlet end of the second heat exchange pipe 122. So that the outlet end of the first heat exchanging pipe 121 can be communicated to the inlet end of the second heat exchanging pipe 122, and a three-way valve (not shown in the drawings) can be provided at the communication between the outlet end of the first heat exchanging pipe 121 and the second adapter pipe 1221 and the second heat exchanging pipe 122, so that the refrigerant in the second adapter pipe 1221 can only flow into the second heat exchanging pipe 122.
Further, the water cooling apparatus 100 further includes a condenser (not shown) and a compressor (not shown), the liquid inlet pipe 130 is connected to the liquid outlet end of the condenser, the outlet end of the compressor is connected to the liquid inlet end of the condenser, and the outlet end of the second heat exchanging pipe 122 is connected to the inlet end of the compressor. The compressor sucks the low-temperature and low-pressure refrigerant gas from the second heat exchange tube 122, drives the piston to compress the refrigerant gas through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to provide power for the circulation of the water cooling device 100. The condenser absorbs heat of the refrigerant gas of high temperature and high pressure to reduce its temperature and pressure to be inputted again into the liquid inlet pipe 130, thereby circulating to provide cooling capacity to the cooling water device 100.
In the above embodiment, a set of condenser and compressor can be realized through the liquid inlet pipe 130 and the three-way valve 131 to provide condensing agent for the first heat exchange pipe 121 and the second heat exchange pipe 122, so that the number and volume of the equipment are reduced, and the cost is reduced. Of course, in other embodiments, the first heat exchanging pipe 121 and the second heat exchanging pipe 122 may adopt a separate condenser and a separate compressor, which are provided with a refrigerant, respectively, and are not limited herein.
In some embodiments, as shown in fig. 1 and 3, that is, the cold water device 100 further includes a tank 140, the tank 140 is filled with a cold storage medium, and the second water pipe 112 and the second heat exchange pipe 122 are disposed in the tank 140 to exchange heat through the cold storage medium in the tank 140. The cold storage medium in the bucket surrounds the second heat exchange tube 122 and the second water tube 112, so that cold energy in the second heat exchange tube 122 can be fully absorbed and stored, and then the cold storage medium is used for cooling the second water tube 112. The cold storage medium may be a gas medium such as air, a liquid medium such as water, or even other solid media, which is not limited herein.
In order to reduce the volume of the water cooling apparatus 100, as shown in fig. 3, and to extend the lengths of the second heat exchanging pipe 122 and the second water pipe 112, the second heat exchanging pipe 122 and the second water pipe 112 are spirally wound in the tank 140, and the pipe path of the spirally arranged second heat exchanging pipe 122 and the second water pipe 112 is longer, so that the path through which the refrigerant and the water flow passes is longer. Therefore, the cold storage medium can absorb and store the cold of the refrigerant more fully, and the inner water flow of the second water pipe 112 can exchange heat with the cold storage medium more fully. The second heat exchange tube 122 and the second water tube 112 which are spirally arranged in a surrounding manner have smaller volumes, so that the heat exchange efficiency is higher, and the water flow temperature can be effectively reduced.
Specifically, the second water pipe 112 is disposed outside the second heat exchanging pipe 122, and the distance between the second heat exchanging pipe 122 and the second water pipe 112 is greater than or equal to a first preset distance, so that water with a lower temperature in the second water pipe 112 cannot be frozen due to a too short distance between the second heat exchanging pipe 122 and the second water pipe 112, and the ice blockage situation is avoided. Specifically, the first preset distance is 10mm, 12mm, 15mm, and the like, and the first preset distance can be adjusted according to actual conditions.
In order to further reduce the volume of the water cooling apparatus 100 and further improve the heat exchange efficiency, as shown in fig. 1, the first water pipes 111 and the first heat exchange pipes 121 are alternately spirally wound around the outside of the tank 140. Firstly, the first water pipe 111 and the first heat exchange pipe 121 are arranged outside the tank body 140, so that the overall size of the water cooling device 100 can be reduced, that is, the water cooling device 100 has a more compact and reasonable structure, and only the first water pipe 111 and the first heat exchange pipe 121 need to be externally provided with heat insulation layers, so that the first heat exchange pipe 121 and the first water pipe 111, and the second heat exchange pipe 122 and the second water pipe 112 do not need to be respectively provided with heat insulation layers, and the installation is simpler and more convenient. Secondly, the pipelines of the first water pipe 111 and the first heat exchange pipe 121 which are arranged in an alternating spiral surrounding manner are longer, so that the path through which the refrigerant and the water flow pass is longer, the contact area between the first water pipe 111 and the first heat exchange pipe 121 is larger, the heat exchange efficiency between the first water pipe 111 and the first heat exchange pipe 121 is higher, and the temperature of the water flow can be effectively and rapidly reduced. In addition, because the first water pipe 111 and the first heat exchange pipe 121 are arranged outside the tank body 140, the cold storage medium in the tank body 140 can play a certain role of cooling the water flow in the first water pipe 111 through the tank body 140, and the first heat exchange pipe 121 outside the tank body 140 can also play a certain role of cooling the cold storage medium in the tank body 140, so that the cold energy of the refrigerant is fully utilized, and the loss of the cold energy is reduced.
Further, in order to prevent the first heat exchange tube 121 from affecting the second water tube 112, the distance between the second water tube 112 and the inner wall of the tank 140 is greater than or equal to a second preset distance, so as to avoid freezing of water with low temperature in the second water tube 112 due to too close distance between the first heat exchange tube 121 and the second water tube 112, and avoid ice blockage. Specifically, the second preset distance is 8mm, 10mm, and the like, and the second preset distance can be adjusted according to actual conditions.
Of course, in other embodiments, the first heat exchanging pipe 121 and the first water pipe 111 may not be disposed outside the tank 140, and are not limited herein.
In order to improve the heat exchange capability between the cold storage medium in the tank 140 and the second heat exchange tube 122 and the second water tube 112, as shown in fig. 3, the cooling water device 100 of the embodiment of the present application further includes a stirring member 141, the second heat exchange tube 122 is disposed around the stirring member 141, the stirring member 141 is located at the middle position of the second heat exchange tube 122, the rotation of the stirring member 141 can accelerate the flow of the cold storage medium in the tank 140, homogenize the temperature of the cold storage medium in the tank 140, promote the second heat exchange tube 122 to absorb the heat of the cold storage medium, and promote the cold storage medium to absorb the heat of the second water tube 112.
Specifically, the stirring member 141 includes a stirring blade 1411 and a pump body 1412, the stirring blade 1411 is located in the middle of the second heat exchange tube 122, the pump body 1412 is located at the top of the tank 140, and the pump body 1412 drives the stirring blade 1411 to rotate so as to drive the cold storage medium to flow.
Further, a second sensor (not shown in the figure) is arranged in the tank 140, the second sensor monitors the temperature in the tank 140, the stirring piece 141 rotates and mixes the cold storage medium in the tank 140, and the temperature of the cold storage medium in the tank 140 monitored by the second sensor is more accurate.

Another embodiment of the present application discloses a method for controlling a water cooling device, where the water cooling device is the water cooling device in any one of the embodiments, and the method includes the following steps:
when the water inlet of the water cooling device is available, at least the following conditions are included:
s11: and in response to the fact that the water inlet temperature of the first water pipe is higher than a first preset temperature, the first heat exchange pipe and the second heat exchange pipe are filled with condensing agents.
When the first water inlet temperature of the first water pipe is higher than the first preset temperature, the water inlet temperature is higher, a larger heat exchange amount is needed, condensing agents are introduced into the first heat exchange pipe and the second heat exchange pipe, the condensing agents flowing through the first heat exchange pipe fully absorb the heat of water flow in the first water pipe, the heat exchange amount of the first heat exchange pipe is large, the heat exchange amount efficiency is high, the water inlet is quickly reduced to a certain temperature, and the water in the first water pipe cannot reach the freezing temperature. Then the water in the first water pipe flows to the second water pipe, the condensing agent in the second heat exchange pipe absorbs the heat of the cold accumulation medium, the cold accumulation medium after the temperature is reduced continuously carries out relatively slow cooling on the water flow of the second water pipe, the cold quantity of the cold accumulation medium is controllable, the water in the second water pipe can be ensured not to be frozen, and the phenomenon of ice blockage of the water pipe is avoided. The water flow in the water pipe is subjected to two-stage cooling processes, so that the water temperature is fully reduced, and ice blockage is prevented.
Wherein, the first preset temperature can be 25 ℃, 30 ℃, 35 ℃ and the like.
It should be noted that the outlet end of the first heat exchange tube may be communicated with the inlet end of the second heat exchange tube, and the condensing agent flowing through the first heat exchange tube fully absorbs the heat of the water flow in the first water tube, so as to rapidly reduce the water flow in the first water tube to a certain temperature, but the water in the first water tube does not reach the freezing temperature. The coolant then flows to the second heat exchange tube, the coolant still being at a temperature less than the temperature of the cold storage medium. The outlet end of the first heat exchange pipe is communicated with the inlet end of the second heat exchange pipe, so that the condensing agent can be fully utilized, and the water flow in the water pipe is subjected to two-stage cooling process, so that the water temperature is fully reduced, and ice blockage is prevented.
Of course, the first heat exchange pipe and the second heat exchange pipe may adopt a separate condenser and a separate compressor, respectively, to which a condensing agent is supplied, and are not limited herein.
S12: in response to the fact that the water inlet temperature of the first water pipe is higher than a second preset temperature and lower than or equal to a first preset temperature, and the temperature of the cold accumulation medium is higher than or equal to a third preset temperature, the first heat exchange pipe and the second heat exchange pipe are filled with condensing agents; wherein the second preset temperature is lower than the first preset temperature.
Responding to the water inlet temperature of the first water pipe, wherein the water inlet temperature is higher than a second preset temperature and lower than or equal to a first preset temperature. At this moment, the water inlet temperature of the first water pipe is moderate, and if the temperature of the cold accumulation medium is low, the temperature of the water inlet can be reduced only by the cold accumulation medium with low temperature, so that the temperature of the cold accumulation medium is required to be monitored. The second preset temperature is less than the first preset temperature, and specifically, the second preset temperature is 10 ℃, 15 ℃, 20 ℃ or the like.
Specifically, if the temperature of the cold accumulation medium is lower than the third preset temperature, the inlet water is cooled only by the cold accumulation medium with the lower temperature, and the compressor is not started, namely, no condensing agent is introduced into the first heat exchange tube and the second heat exchange tube.
If the temperature of the cold accumulation medium is more than or equal to the third preset temperature, the temperature of the cold accumulation medium is higher, and the heat exchange effect may not meet the requirement, so that the compressor can be started, and condensing agents are introduced into the first heat exchange tube and the second heat exchange tube. The condensing agent flowing through the first heat exchange tube fully absorbs the heat of water flow in the first water tube, the heat exchange amount of the first heat exchange tube is large, the heat exchange amount efficiency is high, the inflow water is quickly reduced to a certain temperature, and the water in the first water tube cannot reach the freezing temperature.

Specifically, the third preset temperature is 4 ℃, 5 ℃, 6 ℃ or the like.
S13: and in response to the water inlet temperature of the first water pipe being less than or equal to a second preset temperature and the temperature of the cold accumulation medium being greater than or equal to a third preset temperature, the second heat exchange pipe is introduced with a condensing agent.
The water inlet temperature of the first water pipe is less than or equal to the second preset temperature, the water inlet temperature is low at the moment, only the second heat exchange pipe can be utilized to carry out indirect heat exchange through a cold accumulation medium, and the condition that the water pipe is blocked by ice is avoided. Meanwhile, if the temperature of the cold accumulation medium is low, the temperature of the cold accumulation medium is monitored only by utilizing the cold accumulation medium with low temperature to cool the inlet water.
Specifically, if the temperature of the cold accumulation medium is greater than or equal to the third preset temperature, the temperature of the cold accumulation medium is high, and the heat exchange effect may not meet the requirement, so that the compressor can be started, and the condensing agent is introduced into the second heat exchange tube. The condensing agent in the second heat exchange pipe absorbs the heat of the cold accumulation medium, the cold accumulation medium after the temperature is reduced continuously carries out relatively slow cooling on the water flow of the second water pipe, the cold quantity of the cold accumulation medium is controllable, the water in the second water pipe can be guaranteed not to be frozen, and the phenomenon of ice blockage of the water pipe is avoided.
If the temperature of the cold accumulation medium is lower than the fourth preset temperature, the temperature of the cold accumulation medium is lower, the inlet water can be cooled only by the cold accumulation medium with the lower temperature, the compressor can stop working, and the first heat exchange tube and the second heat exchange tube are not filled with condensing agents. Specifically, the fourth preset temperature may be 2 ℃ or 3 ℃ or the like.
Further, if the cold water device includes a tank body and a stirring piece, the cold accumulation medium is arranged in the tank body, and when the cold water device enters water, the stirring piece is started, so that the temperature of the cold accumulation medium is uniform, and heat exchange and the temperature of the cold accumulation medium are favorably measured.
The control method of the instant water cooling apparatus further includes:
when the cold water device is not filled with water:
in order to effectively reduce the temperature of the inlet water and ensure the cooling effect when the water cooling device has the inlet water, the cold accumulation medium needs to be kept at a lower temperature all the time.
