[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The core of the present application is to provide a water cooling system, which has a lower metal ion concentration in the coolant output by the water cooling system compared with the related art. Another core of the present application is to provide a water cooling unit including the water cooling system.

[0036] The present application provides a water cooling system, including a heat exchanger 1, a water return channel 2, a water outlet channel 3 and a deionizer 4. The heat exchanger 1 has a refrigeration channel and a heat exchange channel, the refrigeration channel is used for the flow of refrigerant, the heat exchange channel is used for the flow of coolant, and the refrigerant and the coolant exchange heat through the heat exchanger 1; the water return channel 2 is connected to the inlet of the heat exchange channel; the water outlet channel 3 is connected to the outlet of the heat exchange channel; the deionizer 4 is arranged in the water return channel 2, and is used for ion filtration, so that the coolant with a metal ion concentration less than or equal to a set threshold value flows into the heat exchange channel.

[0037] Please refer to Figure 1 and Figure 2 The water cooling system is equipped with a heat exchanger 1, and a return water channel 2 is connected to the inlet of the heat exchange channel of the heat exchanger 1. The heat exchange channel of the heat exchanger 1 can receive the coolant in the return water channel 2, and then the refrigerant in the refrigeration channel absorbs the heat of the coolant in the heat exchange channel to obtain a coolant with a reduced temperature. The refrigerant and the coolant can be water or any other type of refrigerant; and a water outlet channel 3 is connected to the outlet of the heat exchange channel of the heat exchanger 1, so that the coolant can be discharged into the water outlet channel 3. When in use, the inlet end of the return water channel 2 is connected to a liquid supply channel, such as a water pool or a cooling channel outlet end arranged in a designated space, and the outlet end of the water outlet channel 3 is connected to the inlet end of the cooling channel arranged in the designated space. The water cooling system can receive uncooled coolant and cool it, and the coolant can be guided to flow to the designated space through the water outlet channel 3 to cool the designated space.

[0038] A deionizer 4 is arranged on the return water channel 2, so that the refrigerant flowing through the return water channel 2 can be first subjected to ion filtration and then input into the heat exchange channel of the heat exchanger 1, so as to control the metal ion concentration of the refrigerant flowing into the heat exchange channel of the heat exchanger 1 to be less than or equal to the set threshold value, so as to effectively reduce the metal ion concentration of the refrigerant discharged from the water cooling system.

[0039] Please refer to Figure 1 and Figure 2On the basis of the above embodiment, a conductivity meter 5 is provided in the water outlet channel 3 for detecting the conductivity of the refrigerant discharged from the heat exchange channel, so as to be able to detect the conductivity of the refrigerant discharged from the water cooling system, so as to be able to determine the concentration of metal ions in the refrigerant, and then the start and stop of each component in the water cooling system can be controlled to ensure the metal ion concentration of the output refrigerant.

[0040] On the basis of the above embodiment, the return channel 2 includes a main channel 211 and a branch channel 212. The main channel 211 is provided with a first switch valve 6, and the branch channel 212 is provided with a deionizer 4 and a second switch valve 7. The main channel 211 is connected in parallel to the branch channel 212, and the main channel 211 and the branch channel 212 are both conductively connected to the inlet of the heat exchange channel.

[0041] Please refer to Figure 1 The return water channel 2 includes two channels arranged in parallel, namely a main channel 211 and a branch channel 212. A first switch valve 6 is arranged on the main channel 211, and a second switch valve 7 and a deionizer 4 are arranged on the branch channel 212. The water cooling system includes two passages for providing coolant to the heat exchanger 1. By opening and closing the first switch valve 6 and the second switch valve 7, one or both of them can be selected to provide coolant to the heat exchanger 1.

[0042] When in use, the first switch valve 6 is controlled to open, and the second switch valve 7 and the deionizer 4 are controlled to close, so as to provide the coolant to the heat exchanger 1 through the main channel 211; and when the metal ion concentration in the output coolant of the water cooling system exceeds the set threshold, the first switch valve 6 is controlled to close, and the second switch valve 7 and the deionizer 4 are controlled to open, so as to provide the deionized coolant to the heat exchanger 1 through the branch channel 212.

[0043] Based on the above embodiment, the water cooling system also includes a controller, and the conductivity meter 5, the deionizer 4, the first switch valve 6 and the second switch valve 7 are all connected to the controller signal to control the start and stop of the deionizer 4, the first switch valve 6 and the second switch valve 7 according to the conductivity signal.

[0044] Please refer to Figure 1 In this embodiment, the first switch valve 6 and the second switch valve 7 are both solenoid valves, and the deionizer 4 is provided with an automatic opening and closing structure. The controller signal connects the first switch valve 6, the second switch valve 7 and the deionizer 4, so that the deionizer 4, the first switch valve 6 and the second switch valve 7 can be automatically opened and closed by the controller. Correspondingly, the controller signal is connected to the conductivity meter 5, and the controller can receive the detection result of the conductivity meter 5, so as to determine whether the metal ion concentration of the output coolant of the water cooling system exceeds the set threshold.

[0045] During use, when the metal ion concentration in the output refrigerant of the water cooling system exceeds the set threshold, the controller controls the deionizer 4 and the second switch valve 7 to open, and controls the first switch valve 6 to close; when the metal ion concentration in the output refrigerant of the water cooling system does not exceed the set threshold, the controller controls the deionizer 4 and the second switch valve 7 to close, and controls the first switch valve 6 to open.

[0046] On the basis of the above embodiment, the first switch valve 6 is a manual valve, so that the flow resistance of the scoring channel 212 is greater than the flow resistance of the main channel 211 .

[0047] Please refer to Figure 1 Compared with the solenoid valve, the flow resistance of the manual valve is larger. In this embodiment, the first switch valve 6 adopts a manual valve to increase the resistance of the coolant to provide the coolant to the heat exchanger 1 through the main channel 211. The first switch valve 6, the second switch valve 7 and the deionizer 4 can be controlled to open at the same time. Since the resistance of providing the coolant to the heat exchanger 1 through the main channel 211 is less than the resistance of providing the coolant to the heat exchanger 1 through the branch channel 212, the flow rate of the main channel 211 is greater than the flow rate of the branch channel 212. With this arrangement, the service life of the water cooling system can be extended while purifying the water quality.

[0048] Based on the above embodiment, the return water channel 2 includes a first main channel 221 and a second main channel 222, one end of the first main channel 221 is connected to the inlet of the heat exchange channel, and the other end is connected to the outlet of the deionizer 4, and the second main channel 222 is connected to the inlet of the deionizer 4.

[0049] Please refer to Figure 2 In this embodiment, the return channel 2 is divided into two sections, namely a first main channel 221 and a second main channel 222. The left end of the first main channel 221 is connected to the inlet of the heat exchange channel of the heat exchanger 1, the right end of the first main channel 221 is connected to the outlet of the deionizer 4, the left end of the second main channel 222 is connected to the inlet of the deionizer 4, and the right end of the second main channel 222 is connected to the liquid supply channel when in use. Therefore, while continuously delivering the refrigerant to the heat exchanger 1, the delivered refrigerant can be deionized.

[0050] In some specific embodiments, the heat exchange channel, the return water channel 2 and the outlet water channel 3 are all stainless steel tubes to reduce the precipitation of copper ions in the channels.

[0051] Preferably, in some specific embodiments, the heat exchange channel, the return water channel 2 and the outlet water channel 3 are all plastic tubes, such as plastic tubes or rubber tubes, so as to reduce the precipitation of metal ions in the channels.

[0052] On the basis of the above-mentioned embodiment, the heat exchange channel includes a main water inlet channel 11, a main drainage channel 12 and a plurality of water-passing channels 13; one end of the water-passing channel 13 is welded to the main water inlet channel 11, and the other end is welded to the main drainage channel 12, and the inner surface of the welding position between the water-passing channel 13 and the main water inlet channel 11 and the inner surface of the welding position between the water-passing channel 13 and the main drainage channel 12 are coated with a nano-plating layer.

[0053] Please refer to Figure 3 The upper water inlet main channel 11 and the lower drainage main channel 12 both extend in the transverse direction, the water-passing channel 13 is located between the water inlet main channel 11 and the drainage main channel 12, the upper end of the water-passing channel 13 abuts the water inlet main channel 11 and is connected as a whole by welding, and the lower end of the water-passing channel 13 abuts the drainage main channel 12 and is connected as a whole by welding. Since the welding position will inevitably destroy the original structure of the stainless steel pipe and will be doped with welding impurities, in order to reduce the precipitation of metal ions, the inner surface of the return water channel 2 is plated with nano materials at the welding position of the return water channel 2. It should be noted that the type of nano-plating is not limited, as long as it can achieve the reduction of metal ion precipitation, for example, titanium dioxide coating or silane coating can be used.

[0054] On the basis of the above embodiment, the water outlet channel 3 is provided with a water pump 8 and a filter 9. The water pump 8 is a shielded pump, and the pump head of the water pump 8 is a plastic structure, and the impeller and rotor of the water pump 8 are plastic one-piece injection molding structures. The water pump 8 can be used to extract the refrigerant in the heat exchanger 1 and provide power for the refrigerant to flow to the designated space. The filter 9 is located on the outlet side of the water pump 8. The water cooling system can filter the refrigerant before transporting it out. Since the impeller, rotor and pump head in the water pump 8 are usually in contact with the refrigerant flowing through it, in order to reduce the precipitation of metal ions in the water pump 8, the water pump 8 adopts a shielded pump, and the pump head, impeller and rotor are all plastic structures, and the impeller and rotor are integrally injection molded.

[0055] Please refer to Figure 3 On the basis of the above embodiment, it also includes a water diversion channel, which is connected in parallel and conductively to the outlet of the heat exchange channel of the heat exchanger 1, and the water diversion channel is provided with a third switch valve 10, so that when necessary, the third switch valve can be opened to divert the refrigerant discharged from the heat exchanger. For example, the signal of the third switch valve 10 is connected to the controller to control the opening and closing of the third switch valve 10 according to the detection result of the conductivity meter 5. When in use, when the metal ion concentration of the refrigerant output by the water cooling system exceeds the set threshold, the third switch valve 10 is controlled to open to discharge the refrigerant output by the heat exchanger 1.

[0056] It should be noted that the “channel” mentioned above may refer to a pipeline, or a hole opened inside a physical structure, etc.

[0057] In addition to the above-mentioned water cooling system, the present application also provides a water cooling unit including the water cooling system disclosed in the above-mentioned embodiment. For the structures of other parts of the water cooling unit, please refer to the prior art and will not be described in detail herein.
