Description

Technical Field

[0001] The utility model relates to the technical field of water chiller cooling, and more specifically to a device for detecting the performance of cooling liquid of a water chiller. Background Art

[0002] In existing energy storage liquid cooling or other liquid cooling equipment, in order to reduce the evaporation of the coolant and increase the life of the coolant, most of them use a closed liquid circulation system. However, the entire liquid cooling system is composed of multiple parts or equipment, which have various materials and different cleanliness states, which will cause large differences in the life of the coolant. When the coolant reaches its service life, its thermal conductivity will decrease, and its corrosiveness to related equipment will increase, which will increase energy consumption and cause an increased risk of leakage due to corrosion. Existing chillers (liquid cooling hosts) generally only detect the temperature and pressure of the entire liquid cooling system, and cannot detect the performance indicators of its coolant. However, the detection devices for testing the performance of coolant in the prior art cannot effectively remove impurities in the coolant, which affects the detection accuracy. For example, patent No. CN201710422117.2 is a device for detecting a coolant temperature sensor, which includes a coolant temperature sensor, a compression spring, a plywood, a container plate, a slot cover, a heat pipe, a heating slot, a thermocouple temperature sensor, an exhaust duct, a torsion spring, and an air blocking door. The device structure cannot remove impurities in the coolant, and the impurities present in the coolant after long-term use will affect the detection accuracy. Utility Model Content

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0029] See also Figure 1-7 , the utility model provides a technical solution:

[0030] A device for detecting the performance of a chiller coolant, comprising:

[0031] A coolant information collection unit 1, the inlet of which is connected to the coolant circulation pipeline, and the outlet of which is connected to the liquid inlet of the chiller, for detecting and collecting the performance parameters of the circulating coolant;

[0032] The coolant filter unit 2 is connected to the coolant information collection unit 1 and is used to filter out impurities in the coolant to be detected;

[0033] The controller 3 is electrically connected to the coolant information collection unit 1;

[0034] The alarm device 4 is electrically connected to the controller 3 and is used for giving an alarm prompt under the control of the controller 3 .

[0035] The working principle and technical effects of the above technical solution are as follows:

[0036] The utility model is provided with a coolant information acquisition unit 1 inside, and the inlet of the coolant information acquisition unit 1 can be connected to the coolant circulation pipeline, and the outlet of the coolant information acquisition unit 1 can be connected to the liquid inlet of the chiller, and the coolant circulating through the coolant circulation pipeline enters the coolant information acquisition unit 1, and the performance parameters of the circulating coolant are detected and collected by the coolant information acquisition unit 1. Various types of sensors such as PH detection sensors, conductivity sensors, temperature sensors, and pressure sensors can be set in the coolant information acquisition unit 1 to effectively detect various performance parameters of the coolant, which is convenient for more comprehensive judgment. The utility model is provided with a coolant filter unit 2 for filtering impurities in the coolant to be detected, which can reduce the influence of impurities on the coolant performance detection results and improve the accuracy of the coolant performance detection; after the coolant information acquisition unit 1 detects and collects the performance parameters of the circulating coolant, the data signal is transmitted to the controller 3. When the performance parameters of the coolant are not within the preset range, the controller 3 controls the alarm 4 to give an alarm prompt, which is convenient for timely replacement of the coolant to ensure the cooling effect.

[0037] The coolant information acquisition unit 1 includes a detection box 11, the inlet of the detection box 11 is connected to the coolant circulation pipeline, and the outlet of the detection box 11 is connected to the liquid inlet of the chiller; a pH detection sensor and a conductivity sensor are installed in the detection box 11, and the pH detection sensor and the conductivity sensor are both electrically connected to the controller 3. The pH detection sensor is used to detect the pH value of the coolant. The pH value of the coolant can reflect its acidity and alkalinity, which is of great significance to the stability and corrosiveness of the liquid cooling system; the conductivity sensor is used to detect the conductivity of the coolant. Conductivity is one of the important indicators for evaluating the performance of the coolant, especially in the application of metal pipes and coolers. A temperature sensor is also installed in the detection box 11, and the temperature sensor is electrically connected to the controller 3. The temperature sensor is used to detect the temperature of the coolant, because the performance of the coolant is closely related to its performance at different temperatures.

[0038] A box cover 12 with an inlet is provided at one end of the detection box 11, and the coolant filter unit 2 includes a disc seat 1 21 and a disc seat 22 which are sealed and rotatably connected in the detection box 11, and the disc seat 1 21 is located between the disc seat 22 and the box cover 12; multiple through-tube holes of the disc seat 1 21 and multiple through-tube holes of the disc seat 22 are connected through multiple cylindrical filter screens 23, and the open ends of the multiple cylindrical filter screens 23 are connected to the diversion cavity formed between the disc seat 1 21 and the box cover 12; the filter holes of the multiple cylindrical filter screens 23 are located in the detection cavity formed between the disc seat 1 21 and the disc seat 22; an output pipe 24 with an outlet is sealed and rotatably connected in the center hole of the disc seat 22; the pH detection sensor and the conductivity sensor are both located in the detection cavity.

[0039] When testing the coolant, the coolant enters the diversion cavity formed between the disc seat 21 and the box cover 12 through the inlet of the box cover 12, and the coolant in the diversion cavity enters the multiple cylindrical filter screens 23 through the open ends of the multiple cylindrical filter screens 23. After being filtered and removed by the multiple cylindrical filter screens 23, the coolant enters the detection cavity between the multiple cylindrical filter screens 23 and the detection box 11 so as to be detected by the PH detection sensor and the conductivity sensor, and can be detected by other sensors installed in the detection cavity. Detection after removing impurities is beneficial to improving the accuracy of the detection result.

[0040] The output tube 24 is fixed to one end of the detection box 11 away from the box cover 12 by a bracket 25 , so as to improve the installation stability of the output tube 24 .

[0041] The closed end of the cylindrical filter 23 passes through the outside of the detection cavity, and a sliding warning guide rod 26 is sealed in the through hole of the closed end of the cylindrical filter 23. The warning guide rod 26 is inserted into one end of the cylindrical filter 23 to fix the sliding plug 27. The sliding plug 27 is on the inner wall of the cylindrical filter 23, and a spring body 28 is fixed between the sliding plug 27 and the closed end of the cylindrical filter 23. When there are a lot of impurities accumulated in the cylindrical filter 23, as the coolant flows, the pressure on the sliding plug 27 becomes larger. At this time, the sliding plug 27 drives the warning guide rod 26 to move in the direction away from the cylindrical filter 23 and compresses the spring body 28. The staff can make a certain judgment on the impurity accumulation in the cylindrical filter 23 according to the length of the warning guide rod 26, so as to facilitate the timely cleaning of impurities and prevent the cylindrical filter 23 from being blocked and the coolant from flowing.

[0042] An outer gear ring 29 is fixed on the outer side of the second disc seat 22, and the outer gear ring 29 is meshed with the gear at the output end of the rotary motor 5, and the rotary motor 5 is installed outside the detection box 11. After the rotary motor 5 is started, it can drive the gear to rotate, and the gear meshing outer gear ring 29 rotates, thereby mobilizing the second disc seat 22 to rotate in the detection box 11. When the second disc seat 22 rotates, it drives the multiple cylindrical filter screens 23 to rotate, which can improve the flow effect of the coolant entering the detection chamber, and the outer wall of the cylindrical filter screen 23 is fixed with a swirl impeller, which is located in the detection chamber, and the coolant in the detection chamber can be mixed and swirled by the swirl impeller to improve the detection accuracy.

[0043] A scraper is fixed in the detection box 11, and the scraper is slidably matched with the side surface of the disc seat 21 close to the box cover 12. When the disc seat 22 drives the multiple cylindrical filter screens 23 and the disc seat 21 to rotate, the disc seat 21 changes the contact position with the scraper, so that the scraper scrapes off the impurities on the disc seat 21 to prevent impurities in the coolant from accumulating on the side surface of the disc seat 21 close to the box cover 12.

[0044] The alarm 4 is an audible and visual alarm 4, which can give an alarm under the control of the controller 3.
