[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0032] The core of the utility model provides a kind of CDU water leakage detection structure, water immersion rope can be effectively avoided in the connecting operation with box body damage.

[0033] The specific embodiment one of the CDU water leakage detection structure provided by the utility model is as shown in Figure 1 And Figure 2 As shown, including box body 1, when being applied to CDU, water route element for storing liquid or passing liquid is usually arranged in the box body, for example, heat exchange equipment, water storage equipment, expansion tank, valve, pipeline structure etc.

[0034] As shown in Figure 1 Water immersion rope 2 is arranged in box body 1, water immersion rope 2 can detect whether water leakage occurs based on the liquid conductive working principle, and is usually used in cooperation with water immersion controller 27 connected thereto.When water immersion rope 2 contacts water at any position, the sensing line on water immersion rope 2 will be in a similar short-circuit condition of conductor, and water immersion controller 27 judges the water leakage condition according to the change of resistance of water immersion rope 2, and sends out audible and visual alarm signal.

[0035] Along the extension direction of water immersion rope 2, multiple fixing pieces 3 fix water immersion rope 2 on the inner wall of box body 1. Fixing piece 3 includes connecting piece 32 and buffer piece 31.

[0036] Connecting piece 32 fixes the preset connecting point 21 on water immersion rope 2 to box body 1, and buffer piece 31 is located between the corresponding preset connecting point 21 and connecting piece 32, to separate the corresponding connecting piece 32 and preset connecting point 21.

[0037] Among them, the preset connecting point 21 is a point or a small section on water immersion rope 2 for setting fixing piece 3, and the position and number of preset connecting point 21 can be set according to the available space in box body 1 and the length of water immersion rope 2. For example, one preset connecting point 21 can be set every same length on water immersion rope 2, or one or two preset connecting points 21 are set at each inflection point in the extension direction of water immersion rope 2.

[0038] Among them, buffer piece 31 can protect the preset connecting point 21 on water immersion rope 2, specifically, buffer piece 31 adheres or wraps part of preset connecting point 21 (specifically refers to a part on the outer periphery of preset connecting point 21), as shown in Figure 2As shown, the buffer 31 wraps around a portion of the preset connecting point 21 away from the inner wall of the cabinet 1. The connecting piece 32 corresponds to the wrapping or wrapping of at least part of the buffer 31, so as to realize the fixation of the buffer 31 and the preset connecting point 21.

[0039] The water leakage detection structure of the CDU in the embodiment includes the water immersion rope 2, which can detect the water leakage of the equipment in the cabinet 1 and find the water leakage in time. The water immersion rope 2 is isolated and buffered by the buffer 31 and then fixed to the cabinet 1 by the connecting piece 32, which can effectively protect the water immersion rope 2, avoid damaging the line part of the water immersion rope 2 during connection operation, and affect the detection capability. It can avoid affecting the normal use of the equipment due to water leakage, and improve the safety of equipment operation.

[0040] As shown in Figure 2 The buffer 31 includes a rubber strip, which has a certain flexibility and can provide a certain buffering effect. Since the rubber strip also has adhesion ability, the preset connecting point on the water immersion rope 2 can be adhesively fixed with the connecting piece 32, so that the corresponding preset connecting point 21 on the water immersion rope 2 is stably connected to the connecting piece 32.

[0041] During installation, the preset connecting point 21 on the water immersion rope 2 can be selected first, the rubber strip can be wrapped around the preset connecting point 21 on the water immersion rope 2 within a certain angle range, and then the connecting piece 32 can be fixed. Then the connecting piece 32 is fixed to the cabinet 1; or the positional relationship between the connecting piece 32 and the corresponding preset connecting point 21 is determined and preliminarily installed, and then the gap therebetween is filled with glue, which serves as the rubber strip after solidification.

[0042] Of course, in other embodiments, the buffer 31 can also be selected from rubber parts, buffer foams and other structures or materials; the buffer 31 can have only one material or structure, such as only a rubber strip, or multiple materials or structures can be used in combination. When the buffer 31 does not have adhesion ability, the buffer 31, the connecting piece 32 and the preset connecting point 21 can be relatively fixed by extrusion force, clamping force and the like.

[0043] As shown in Figure 2 The preset connecting point 21 is close to the inner wall of the cabinet 1 and adheres to the inner wall of the cabinet 1, so as to ensure the sensitivity of the water immersion rope 2 in detecting the liquid on the inner wall of the cabinet 1. At this time, the buffer 31 can contact or not contact the inner wall of the cabinet 1 on one side or both sides of the preset connecting point 21. Of course, in other embodiments, when the water immersion rope 2 is separated from the cabinet 1 by the connecting piece 32 and / or the buffer 31, the thickness of this part is preferably set to a slightly thinner value, so as to ensure the adhesion of the water immersion rope 2 to the cabinet 1 and ensure that the liquid leaking into the cabinet 1 can be detected in time.

[0044] As shown in Figure 1As shown, the connecting piece 32 is a sheet metal piece, which has good shaping and supporting capacity, can ensure the reliability of the connection, and has good fixing effect. Specifically, it is a one-piece structure, which is connected or attached to the buffer piece 31 and the box body 1 by bending deformation. Of course, in other embodiments, the connecting piece 32 can also be made of other hard materials such as plastic.

[0045] As shown in Figure 2 The connecting piece 32 has a first connecting part 321 and a second connecting part 322 fixed to the outer circumferential surface of the first connecting part 321. The first connecting part 321 is attached or surrounded at least partially to the corresponding buffer piece 31 (mainly referring to the outer circumferential surface of the buffer piece 31) along the circumference of the water immersion rope 2. The second connecting part 322 is fixed to the box body 1 by a fastener 323. Specifically, the second connecting part 322 can be directly fixed to the box body 1 by a fastener 323 such as a bolt or a screw, which is convenient to assemble. In addition, in order to ensure the stability of the connection, the second connecting part 322 can be attached to the inner wall of the box body 1.

[0046] The first connecting part 321 is a connecting pressing plate 3211 with a groove, which buckles the corresponding buffer piece 31 and the preset connecting point 21 to the inner wall of the box body 1. After the preset connecting point 21 is preliminarily positioned on the inner wall of the box body 1, the buffer piece 31 and the connecting piece 32 can be assembled, which can more flexibly adjust and determine the actual installation position of the preset connecting point 21 according to the actual situation.

[0047] At this time, the forming method of the connecting pressing plate 3211 can be that after the buffer piece 31 and the preset connecting point 21 are positioned on the inner wall of the box body 1, a sheet structure is bent twice to form the connecting pressing plate 3211, which buckles the buffer piece 31 and the preset connecting point 21, and the remaining part serves as the second connecting part 322.

[0048] Of course, in other embodiments, the first connecting part 321 can also be provided in other ways. For details, refer to the embodiment shown in Figure 3 The first connecting part 321 is a connecting ring 3212 that fully wraps the corresponding preset connecting point 21. Correspondingly, the buffer piece 31 also fully wraps the corresponding preset connecting point 21.

[0049] At this time, the forming method of the connecting ring 3212 can be that after a sheet structure surrounds the corresponding buffer piece 31, the two free ends are pinched to form the second connecting part 322; or the first end to the middle part of a sheet structure surrounds the corresponding buffer piece 31 to form the connecting ring 3212, and the middle part and the remaining second end form the second connecting part 322. The first end and the middle part of the sheet structure can be fixed together by welding, bonding or other methods. At this time, the connection between the connecting piece 32 and the buffer piece 31 and the corresponding preset connecting point 21 is firm.

[0050] Meanwhile, after the connecting ring 3212 preliminarily connects or positions the buffer 31, the shape of the connecting piece 32 can be adjusted, so that the side close to the wall of the box 1 is flatly arranged to fit the flat wall of the box 1, thereby ensuring the reliability of the connection; and the side away from the wall of the box 1 is arranged in an arc shape to reduce the corners and the possibility of collision or scratching with other equipment.

[0051] The second connecting part 322 is a connecting sheet, which is simple in structure and can be fitted with the inner wall of the box 1 to ensure the stability of the connection and reduce the occupied space. The second connecting part 322 can be one or more. For example, Figure 2 and Figure 3 In the embodiments, one second connecting part 322 is arranged, and only one second connecting part 322 is arranged, which can reduce the connecting points that need to be opened on the box 1, and the connecting piece 32 can be connected to the box 1 by one fastener 323, thereby reducing the damage to the box 1 and reducing the workload required for assembly. In another embodiment, referring to Figure 4 , two second connecting parts 322 are arranged, at this time, the middle part of the connecting piece 32 is a connecting pressing plate 3211, which buckles the buffer 31 and the preset connecting point 21 in the connecting piece 32 on the box 1, and the two free ends of the connecting piece 32 form the second connecting parts 322 and are connected to the box 1, respectively, and at this time, the connecting piece 32 is equivalent to half-enclosing the buffer 31 and pressing the buffer 31 on the box 1. The buffer 31 is selected as a rubber strip, which can be fixed between the box 1 by the adhesive capacity of the rubber strip.

[0052] In addition, in other embodiments, the second connecting part 322 can also be bonded to the box 1, and can also be connected to the box 1 by clamping or other ways.

[0053] On the water immersion rope 2, as shown in Figure 1 , it includes a type of detection section 22 extending along a straight line, and a plurality of fixing pieces 3, for example, 3 or 4, are arranged on the type of detection section 22. At this time, the fixing pieces 3 can also be arranged at equal intervals on the second connecting part 322. When the second connecting part 322 has only one, the second connecting part 322 corresponding to each fastener 323 is located on the same side of the type of detection section 22, which can facilitate assembly.

[0054] In addition, the water immersion rope 2 also includes a type of detection section 23, which can be used to detect specific water path elements 16 in a targeted manner. Specifically, the box 1 has a water path element mounting position 12 for mounting a single water passing or water storing water path element 16, and the type of detection section 23 at least surrounds half of the bottom of the water path element mounting position 12, so that detection can be performed from at least two directions to ensure the detection effect.

[0055] In addition, at the corners of the water immersion rope 2, the preset connecting points 21 are usually arranged to reinforce the fixing pieces 3 and shape the corners.

[0056] Regarding the placement of the water-immersed rope 2 within the housing 1, as follows: Figure 1 As shown, a water-immersing rope 2 can be installed on the bottom surface 11 inside the box. Due to its low position, it can more effectively detect liquid flowing downwards to the bottom of the box. In other embodiments, depending on actual needs, when the box 1 has different layered frame structures, water-immersing ropes 2 can also be adaptively installed on other partitions.

[0057] like Figure 1 As shown, on the bottom surface 11 of the tank, along the first direction X, there are sequentially included a first component area 13, a second component area 14, and a third component area 15. The first component area 13, the second component area 14, and the third component area 15 are respectively used to install water circuit components 16 that can pass through or store water. For example, the first component area 13 can be used to place a pump body, the second component area 14 can be used to place an expansion tank, and the third component area 15 can be used to place a water storage device.

[0058] The water-immersion rope 2 includes, along its extension direction, a first detection section 24, a second detection section 25, and a third detection section 26. The first detection section 24 passes between the second element area 14 and the third element area 15, the second detection section 25 passes through the side of the first element area 13 away from the second element area 14, and the third detection section 26 passes through the side of the third element area 15 away from the second element area 14, thus achieving comprehensive monitoring of different areas.

[0059] The first component area 13 also includes two installation partitions 131 arranged sequentially along the second direction Y. Each installation partition 131 is equipped with a water circuit component. The water immersion rope 2 also includes a part of the structure located between the two installation partitions 131, which can realize the monitoring of different water circuit components 16 in the same area.
