[0036] An embodiment of the present invention discloses an evaporative condenser unit for detecting the loss state of the anode replacement device in the evaporative condenser unit to avoid damage to the condenser in the evaporative condenser unit.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments described here can be implemented in an order other than that shown or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0039] In order to avoid damage to the condenser in the evaporative condenser unit, an embodiment of the present application provides an evaporative condenser unit, which can timely detect the loss state of the anode replacement device in the evaporative condenser unit and timely replace or supplement the anode replacement device. The following is a detailed description:

[0040] Please refer to Figure 1 , the evaporative condenser unit includes a condenser 1, a spraying device 2, an anode replacement device 3, a detection component 4 and a spraying liquid collection tank 5.

[0041] Among them, a heat exchange channel is formed inside the condenser 1 for flowing high-temperature fluid. When the high-temperature fluid passes through the condenser channel, heat conduction will occur between the high-temperature fluid and the wall of the condenser 1, so that heat can be transferred from the wall of the condenser 1 to the outside of the condenser 1, and then the heat can be absorbed by an object outside the condenser 1, such as air, etc., thereby achieving the effect of heat dissipation.

[0042] The spray device 2 therein is used to spray the spray liquid onto the condenser 1. When the spray liquid contacts the outer wall of the condenser 1 or the air near the outer wall, it will absorb heat and evaporate, thereby enabling the outer wall of the condenser 1 and the air near the outer wall to be cooled rapidly. Generally, the spray liquid is water, and of course, it can also be other liquids that are easy to evaporate and absorb heat. To avoid waste of the spray liquid, a spray liquid collection tank 5 is generally provided below the spray device and the condenser to collect the spray liquid that has not undergone a phase change after contacting the outer wall of the condenser 1 or the air near the outer wall.

[0043] Moreover, the reducibility of the material of the anode replacement device 3 is higher than that of the material of the part of the condenser 1 in contact with the liquid, so that the anode replacement device 3 can react with the cathode ions in the spray liquid more easily than the condenser 1. Since the anode replacement device 3 can contact the spray liquid sprayed by the spray device 2 and / or the spray liquid to be sprayed, the cathode ions in the spray liquid sprayed by the spray device 2 and / or the spray liquid to be sprayed can react more directly with the anode replacement device 3, thereby reducing the reaction between the cathode ions in the spray liquid and the exposed material of the condenser 1 and avoiding damage to the condenser.

[0044] It should be noted that the anode replacement device 3 can be a powder-type anode replacement device, or an anode replacement device 3 with structures such as block type, rod type, mesh type, plate type, etc. A specific anode replacement device 3 is a magnesium part. Mg (magnesium) is more likely to react with the cathode ions in the spray liquid than metals such as Al (aluminum), Cu (copper), and Fe (iron). The material of the anode replacement device can be specifically selected according to the material of the condenser to meet the requirement that the reducibility of the material of the anode replacement device 3 is higher than that of the exposed material of the condenser 1.

[0045] In addition, it should be noted that as long as the anode replacement device 3 can contact the spray liquid sprayed by the spray device, the position of the anode replacement device 3 in the evaporative condenser unit is not specifically limited here.

[0046] Furthermore, in order to obtain the loss state of the anode replacement device 3 in the evaporative condenser unit, the present application also provides a detection component 4 in the evaporative condenser unit for detecting the loss state of the anode replacement device 3, so as to obtain the loss state of the anode replacement device 3 in a timely manner and prevent damage to the condenser when the anode replacement device 3 is completely consumed.

[0047] During the use of the evaporative condenser unit, the spray liquid is cyclically sprayed by the spray device 2. Since the anode replacement device 3 can contact the spray liquid and the reducibility of the material of the anode replacement device 3 is stronger than that of the exposed material of the condenser 1, the anode replacement device 3 can react with the cathode ions in the spray liquid prior to the condenser 1, thereby effectively extending the service life of the condenser 1.

[0048] To better avoid the loss of the condenser 1, the present application also provides a detection component 4 in the evaporative condenser unit for detecting the loss state of the anode replacement device 3, so as to obtain the loss state of the anode replacement device 3 in a timely manner and prevent the loss of the condenser when the anode replacement device 3 is completely worn out.

[0049] As a specific embodiment, please refer to Figure 2 : On the basis of the Figure 1 embodiment, it is preferably to completely immerse the anode replacement device 3 in the spray liquid of the spray liquid collection tank 5, so as to increase the contact surface between the anode replacement device 3 and the spray liquid, thereby preferentially ensuring the reaction between the anode replacement device 3 and the cathode ions in the spray liquid, and better protecting the condenser 1 in the evaporative condenser unit.

[0050] To more accurately monitor the loss state of the anode replacement device 3, it is preferably to set the detection component 4 at the position where the anode replacement device 3 is finally worn out. When the anode replacement device 3 is completely immersed in the spray liquid of the spray liquid collection tank 5, since the probability of reaction between each position of the anode replacement device 3 and the cathode ions in the spray liquid is the same, the position where the anode replacement device 3 is finally worn out is the relative geometric center of the anode replacement device 3.

[0051] It is easy to understand that when the shape of the anode replacement device 3 is regular, the relative geometric center of the anode replacement device 3 is the center point of the anode replacement device 3. When the shape of the anode replacement device 3 is irregular, the relative geometric center of the anode replacement device 3 can be determined by the multi-point suspension method.

[0052] As another specific embodiment, please refer to Figure 3 , on the basis of the Figure 1 embodiment, it is preferably to set the detection component 4 at the position where the anode replacement device 3 is finally worn out. If the anode replacement device 3 is semi-immersed in the spray liquid of the spray liquid collection tank 5, that is, the anode replacement device 3 is not in complete contact with the spray liquid of the spray liquid collection tank 5. In this way, compared with the method of completely immersing the anode replacement device 3 in the spray liquid of the spray liquid collection tank 5, the vertical distance between the anode replacement device 3 and the spray liquid sprayed by the spray device is shortened, thereby accelerating the reaction between the anode replacement device 3 and the cathode ions in the spray liquid sprayed by the spray device, and better protecting the condenser 1 in the evaporative condenser unit.

[0053] As a specific implementation method, one or more cavities can be provided in the anode replacement device 3 to semi-immerse the anode replacement device 3 in the spray liquid of the spray liquid collection tank 5, that is, to suspend the anode replacement device 3 on the surface of the spray liquid of the spray liquid collection tank 5.

[0054] It should be noted that if the anode replacement device 3 is semi-immersed in the spray liquid in the spray liquid collection tank 5, the last worn position of the anode replacement device 3 is one end of the anode replacement device 3 that is far from the part in contact with the spray liquid.

[0055] As another specific embodiment, please refer to Figure 4 , in Figure 1 Based on the embodiment, it is preferably to arrange the detection component 4 at the last worn position in the anode replacement device 3. If the anode replacement device 3 is arranged in different temperature ranges, for example, a part of the anode replacement device 3 is arranged in the high-temperature area of the condenser 1, and another part of the anode replacement device 3 is arranged in the low-temperature area of the condenser 1, so as to better solve the problem that the high-temperature area of the condenser 1 is more easily worn. Among them, the high-temperature area of the condenser 1 is generally the upper area of the condenser, and the temperature generally decreases gradually from top to bottom. Of course, it can also be the high-temperature refrigerant inlet of the condenser 1. Specifically, it can be based on multi-point measurement during actual operation.

[0056] It is easy to understand that when the anode replacement device 3 is arranged in different temperature ranges, the last worn position of the anode replacement device 3 is the position arranged in the low-temperature area.

[0057] Based on Figures 1 to 4 the above-mentioned embodiment, in order to make the anode replacement device 3 wear in the direction expected by the user, the surface of part of the anode replacement device can be further subjected to oxidation resistance or insulation treatment, so that the anode replacement device 3 first wears the position that has not been oxidized or insulated in the anode replacement device 3 according to the user's expectation, and then wears the position that has been subjected to oxidation resistance treatment or insulation treatment in the anode replacement device 3.

[0058] It is easy to understand that if the surface of part of the anode replacement device 3 is subjected to oxidation resistance treatment or insulation treatment, the last worn position in the anode replacement device 3 is the position subjected to oxidation resistance treatment or insulation treatment.

[0059] Based on Figures 1 to 4 the above-mentioned embodiment, the installation position of the detection component 4 in the anode replacement device 3 will be described below. Please refer to Figure 5 :

[0060] As a specific implementation, a sealed pressure chamber 6 can be provided inside the anode replacement device 3, so that the pressure difference between the inside and outside of the sealed pressure chamber 6 is maintained within a preset pressure difference range, and the detection component 4 is set as a pressure sensor inside the sealed pressure chamber 6. In this way, when the last worn position of the anode replacement device 3 is worn out, the sealed pressure chamber 6 provided inside the anode replacement device 3 is damaged, and the pressure detected by the pressure sensor will no longer be the pressure inside the sealed pressure chamber, so it can be determined that the anode replacement device 3 needs to be replenished or replaced.

[0061] Furthermore, the detection component 4 can also be set as a pressure sensor outside the anode replacement device 3, but the pressure sensor is connected to the sealed pressure chamber 6 through a pipeline, so that the detection component 4 can measure the pressure inside the sealed pressure chamber at any time. In this way, when the last worn position of the anode replacement device 3 is worn out, the sealed pressure chamber 6 provided inside the anode replacement device 3 is damaged, and the pressure detected by the pressure sensor will no longer be the pressure inside the sealed pressure chamber, so it can be determined that the anode replacement device 3 needs to be replenished or replaced.

[0062] Based on Figure 5 the above-mentioned embodiments, a first substance can also be filled in the sealed pressure chamber 6, and the first substance can react quickly with the spray liquid and / or others, so that the surrounding pressure or temperature changes suddenly. In this way, when the last worn position of the anode replacement device 3 is worn out, the sealed pressure chamber 6 provided inside the anode replacement device 3 is damaged, and the pressure sensor will detect the suddenly changed surrounding pressure, so it can be determined that the anode replacement device 3 needs to be replenished or replaced. The embodiments of the present application Figure 5 compared with the embodiments, because the pressure or temperature around the sealed pressure chamber can be changed suddenly quickly, the requirement for the sensitivity of the pressure sensor is reduced.

[0063] Based on Figures 1 to 4 the above-mentioned embodiments, the anode replacement device 3 can also be provided with a vacuum chamber inside, and the detection component 4 is set as a gas or liquid detection component built inside the vacuum chamber. In this way, when the vacuum chamber is worn out, the gas or liquid detection component built inside the vacuum chamber can detect the external gas or spray liquid, so it can be determined that the vacuum chamber provided inside the anode replacement device 3 is damaged, that is, the anode replacement device 3 is about to be worn out, and the anode replacement device 3 needs to be replenished or replaced.

[0064] In the embodiments of the present application, the detection component is set as a gas or liquid detection component built inside the vacuum chamber of the anode replacement device 3, so that the detection component can detect the wear state of the anode replacement device 3 in different ways, and the reliability of the detection component for detecting the wear state of the anode replacement device 3 is improved.

[0065] Based on the above embodiments, the general spray liquid is recycled, so generally a conveying device for pumping the liquid in the spray liquid collection tank 5 to the spray device 2 is further included. In addition, the evaporative condenser unit mainly uses the phase change heat transfer of an external liquid to transfer the heat in the system to the outside, and generally also includes a housing, a water baffle, etc.; and a circuit for transferring the heat in the system to the outside is formed in the condenser 1, and this circuit is not limited to only tube heat transfer, or fin-tube heat transfer, or plate heat transfer; the spray device 2 includes a liquid driving device, a liquid inlet, a liquid flow channel, a liquid outlet, etc.

[0066] Based on the evaporative condenser unit described in the above embodiments, a processor 7 electrically connected to the detection component can also be provided in the evaporative condenser unit. Please refer to Figure 6 , and from the perspective of the processor, the process of supplementing or replacing the anode replacement device will be described below:

[0067] If the detection component 4 detects an environmental abrupt change amount, the processor 7 is triggered to send an alarm message to prompt the replacement or supplement of the anode replacement device, where the environmental abrupt change amount includes at least one of pressure, temperature, gas or liquid.

[0068] Specifically, based on the above embodiments, when the detection component 4 is a pressure sensor built in the anode replacement device 3, if the sealed pressure cavity provided inside the anode replacement device 3 is damaged, the pressure sensor can monitor the pressure abrupt change amount, and the processor is triggered to send an alarm message to prompt the replacement or supplement of the anode replacement device.

[0069] Further, if a first substance is filled in the sealed pressure cavity in the anode replacement device 3, and the first substance can react quickly with the spray liquid and / or gas, so that the surrounding pressure and / or temperature changes abruptly, when the detection component 4 is a pressure sensor or a temperature sensor provided in the sealed pressure cavity, the processor is used for:

[0070] When receiving the pressure abrupt change amount and / or temperature abrupt change amount monitored by the detection component, send an alarm message to prompt the replacement or supplement of the anode replacement device.

[0071] Further, if a vacuum cavity is provided inside the anode replacement device 3, the detection component 4 is a gas detection component or a liquid detection component provided in the vacuum cavity, and the processor is specifically used for:

[0072] When receiving the gas or liquid detected by the detection component, send an alarm message to prompt the replacement or supplement of the anode replacement device.

[0073] In the embodiments of the present application, the process of prompting to replace or supplement the anode replacement device is described in detail from the perspective of the processor, thereby improving the convenience and intelligence of the evaporative condenser unit in the embodiments of the present application.

[0074] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0075] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
