[0038] See also Figures 1 to 7 As shown, this embodiment provides an integrated device, including a cylinder 1, a filter device 2 and a functional part. Along the length direction of the cylinder 1, one end of the cylinder 1 is provided with a liquid inlet 1011, and the other end of the cylinder 1 is provided with a liquid outlet 1021. At least part of the filter device 2 is located inside the cylinder 1, and the filter device 2 is connected to the liquid inlet 1011; at least one functional part is arranged on the circumferential side wall 103 of the cylinder 1. Functional parts are defined as various components arranged in the air conditioning water system, including but not limited to a filter device, a liquid return device, a liquid replenishing device, a venting device, a pressure sensor, a temperature sensor and an expansion tank joint. It should be noted that when the number of functional parts is one, the functional part is arranged on the circumferential side wall 103 of the cylinder 1; when there are multiple types of functional parts, some of the functional parts may also be arranged at other positions of the integrated device.

[0039] Based on this structure, the integrated device provided in this embodiment, by setting up a cylinder 1, installs the filter device 2 in the cylinder 1, and installs at least one functional component on the circumferential side wall 103 of the cylinder 1. That is to say, the filter device 2 and at least one functional component do not need to be spaced apart along the length direction of the pipeline, thereby shortening the length of the water system and reducing resistance loss.

[0040] When in use, the integrated device is installed in the air conditioning water system, and the high-temperature coolant enters the filter device 2 from the liquid inlet 1011, and the filtered coolant enters the pump body 13 (such as Figure 7), and then sent to the condenser 14 of the air conditioning system by the pump body 13 for cooling. The cooled coolant can be recycled.

[0041] It should be understood that the coolant may be liquid such as water or ethanol.

[0042] In one embodiment, the cylinder 1 includes a first side plate 101, a second side plate 102 and a circumferential side wall 103 arranged around the first side plate 101 and the second side plate 102, the liquid inlet 1011 is arranged on the first side plate 101, and the liquid outlet 1021 is arranged on the second side plate 102. Exemplarily, the cylinder 1 is cylindrical, which can ensure the smooth flow of the coolant. The centers of the liquid inlet 1011 and the liquid outlet 1021 are on the axis of the cylinder 1, which can ensure the straight-through flow of the coolant and reduce the flow resistance.

[0043] In this embodiment, the length direction of the cylinder 1 is the axial direction of the cylinder 1 .

[0044] In other embodiments, the cylinder may also be in other shapes, for example, a rectangular parallelepiped shape, wherein the rectangular parallelepiped cylinder has two end faces arranged opposite to each other along the length direction, and a circumferential side wall between the two end faces, wherein the circumferential side wall includes four planes connected in sequence end to end.

[0045] In order to facilitate replacement of the filter device 2 , the filter device 2 is detachably mounted on the cylinder 1 .

[0046] In one embodiment, see Figures 1 to 3 As shown, the integrated device further comprises a liquid inlet pipe 3 , and the liquid inlet pipe 3 is provided with a flange 31 . Exemplarily, the flange 31 is welded to the liquid inlet pipe 3 .

[0047] Exemplarily, the liquid inlet pipe 3 can be a curved pipe, and the flange edge 31 is welded to one end of the curved pipe. The axes of the two end pipe openings of the curved pipe do not overlap, so that the layout direction of the pipeline can be changed to facilitate the rational use of space and shorten the overall length of the pipeline.

[0048] See also Figure 5 As shown, a mounting portion 25 is provided at the liquid inlet 1011, and the mounting portion 25 is provided with a mounting hole 253, the mounting hole 253 is communicated with the liquid inlet 1011, and a limiting structure is provided on the side of the mounting portion 25 away from the cylinder 1; the mounting portion 25 can be a sleeve structure, and illustratively, the mounting portion 25 can include a first part and a second part, the first part is fixedly installed inside the cylinder, and the second part extends from the outside of the cylinder into the interior and is threadedly connected to the first part, which is convenient for disassembly and maintenance.

[0049] See also Figure 4As shown, the filter device 2 includes a filter screen 201 and a flange 202, the flange 202 is connected to the filter screen 201, and illustratively, the flange 202 and the filter screen 201 are integrally formed. The filter screen 201 is inserted through the mounting hole and the liquid inlet 1011, and the flange 202 abuts against the limiting structure to limit the movement of the filter screen 201 into the cylinder; the flange 202 is clamped and fixed between the flange 31 and the mounting portion 25 by a fastener.

[0050] During installation, the filter screen 201 is passed through the installation hole and the liquid inlet 1011 from the outside of the cylinder in sequence. When the flange 202 abuts against the limiting structure, the filter screen 201 no longer moves into the cylinder. At this time, the mouth of the liquid inlet pipe is aligned with the liquid inlet, and the flange edge 31 abuts against the flange edge. The flange edge 31 and the mounting portion 25 are fixed together by fasteners, so that the flange edge 202 is clamped and fixed between the flange edge 31 and the mounting portion 25.

[0051] Exemplarily, the filter screen 201 is in a cylindrical structure, such as a cylindrical structure, and the cylinder wall and the cylinder bottom of the cylindrical structure are provided with a plurality of mesh holes, and the filtered coolant flows out from the mesh holes.

[0052] In one embodiment, see Figure 5 and Figure 6 As shown, the circumferential surface of the mounting portion 25 is provided with a limiting groove 251, and the limiting groove 251 is clamped with the edge of the liquid inlet 1011 of the cylinder 1. The fastener is a clamp 4, and the mounting portion 25 includes an annular clamping portion 252, and the annular clamping portion 252 is located outside the cylinder 1. The limiting structure is an annular limiting surface 2521 of the annular clamping portion 252 away from the cylinder; the annular clamping portion 252 is arranged opposite to the flange edge 31 at the end of the liquid inlet pipe 3, and is fixedly connected by the clamp 4. Along the axial direction of the filter device 2, the flange 202 is located between the flange edge at the end of the liquid inlet pipe 3 and the annular clamping portion 252, and the flange 202 is clamped by the clamp 4.

[0053] Furthermore, a sealing structure may be provided between the annular clamping portion 252 and the flange edge at the end of the liquid inlet pipe 3 to prevent the coolant from leaking out from the connection.

[0054] A gasket 26 is provided between the mounting portion 25 and the filter screen 201 to provide a seal.

[0055] For example, see Figure 1As shown, the hoop 4 includes two semi-circular halves, one end of the two halves is hinged, and the other end is connected by a fastener, for example, the fastener may include a screw and a nut, one end of the screw is hinged to the other end of one of the halves, the other end of the screw is connected to a nut, and the other end of the other half is provided with a positioning groove, the screw is located in the positioning groove, and the nut is tightened until the nut abuts against the end surface of the positioning groove to achieve the locking of the hoop 4, thereby fixing the annular clamping portion 252, the flange edge 31 at the end of the liquid inlet pipe 3, and the flange 202 of the filter device 2 together. Exemplarily, the nut may be a butterfly nut.

[0056] When the filter device 2 needs to be maintained or replaced, the clamp 4 can be opened to separate the liquid inlet pipe 3 from the flange 202 of the filter device 2, and then the filter device 2 can be directly removed from the installation hole to facilitate maintenance or replacement of the filter device 2.

[0057] It should be noted that the fastener may also include multiple bolts and nuts. The multiple bolts are arranged at intervals along the circumference of the annular clamping portion. The flange and the flange are respectively provided with multiple through holes for the bolts to pass through, and then the nuts are locked on the bolts.

[0058] In one embodiment, see Figure 1 As shown, the functional part includes a liquid replenishing device 5 , and the liquid replenishing device 5 is communicated with the part between the two ends of the liquid inlet pipe 3 .

[0059] When the coolant in the water system is reduced, the liquid replenishing device 5 is used to replenish the coolant in the water system. The replenished coolant enters the filter device 2 from the liquid inlet 1011 for filtration, and then enters the pump body 13 from the liquid outlet 1021 after filtration.

[0060] In this embodiment, the liquid replenishing device 5 includes a liquid replenishing connector 501 , and the liquid replenishing connector 501 is integrated with a liquid replenishing valve 502 .

[0061] Exemplarily, the liquid replenishing connector 501 may be a CQC connector, and the liquid replenishing valve 502 may be a ball valve. Integrating the liquid replenishing valve 502 on the liquid replenishing connector 501 can further shorten the length of the pipeline.

[0062] In one embodiment, see Figure 1 and Figure 3 As shown, the integrated device also includes a liquid outlet pipe 6, which is arranged at the two axial ends of the cylinder 1 opposite to the liquid inlet pipe 3, one end of the liquid outlet pipe 6 is connected to the liquid outlet 1021, and the other end of the liquid outlet pipe 6 is used to be connected to the inlet of the pump body 13, and the liquid outlet pipe 6 is provided with a liquid outlet joint 601, and the liquid outlet joint 601 is integrated with a pump body valve 602.

[0063] Exemplarily, the liquid outlet connector 601 may be a pagoda connector, and the pump body valve 602 may be a ball valve. When the system operates normally, the pump body valve 602 is normally open. When the system is inspected and maintained, the pump body valve 602 is closed.

[0064] Exemplarily, the liquid outlet pipe 6 can be an elbow, one end of the elbow is connected to the liquid outlet 1021, and the other end of the elbow is connected to the pump body valve, so that the layout direction of the pipeline can be changed to facilitate reasonable use of space.

[0065] In one embodiment, a temperature sensor is disposed inside the barrel 1. In this embodiment, the temperature sensor in the integrated device is named as a first temperature sensor 8, and the first temperature sensor 8 is used to detect the temperature of the coolant entering the barrel 1.

[0066] Exemplarily, along the length direction of the barrel 1, the first temperature sensor 8 and the liquid outlet 1021 are located on the same side of the barrel 1; Exemplarily, the first temperature sensor 8 is installed on the second side plate 102 of the barrel 1, at least the sensing head portion of the first temperature sensor 8 is located in the inner cavity of the barrel, and along the height direction of the barrel, the first temperature sensor is located on the side of the liquid outlet close to the bottom of the barrel. In this embodiment, the height direction of the barrel is consistent with the radial direction of the barrel from the top to the bottom.

[0067] Of course, the first temperature sensor can also be installed on the circumferential side wall of the cylinder 1 and be arranged close to the bottom of the cylinder 1.

[0068] In one embodiment, see Figure 1 As shown, the functional part includes an expansion tank joint 11 and a liquid return joint 701. The expansion tank joint 11 is connected to the inner cavity of the cylinder 1. The expansion tank joint 11 is used to connect to the expansion tank 17 (such as Figure 7 ) connection; the liquid return joint 701 and the expansion tank joint 11 are both located on the circumferential side wall of the cylinder 1, and the liquid return joint 701 is integrated with a liquid return check valve 702, and the liquid return joint 701 can be connected to the inner cavity of the cylinder 1 through the liquid return check valve 702.

[0069] For example, the liquid return connector 701 may be a pagoda connector. The liquid return one-way valve 702 is integrated on the liquid return connector 701 to further shorten the length of the pipeline.

[0070] Among them, when the water loss pressure decreases, the gas pressure in the expansion tank is greater than the pressure of the coolant. At this time, the gas expansion squeezes out the coolant in the airbag and replenishes it to the system.

[0071] In this embodiment, see Figure 1 As shown, the expansion tank joint 11 and the liquid return joint 701 are arranged opposite to each other along the radial direction of the cylinder 1 to improve space utilization.

[0072] In other embodiments, the expansion tank joint 11 and the liquid return joint 701 may be set alternatively.

[0073] In one embodiment, the functional component further includes a pressure sensor, and the pressure sensor is used to detect the coolant pressure inside the cylinder 1.

[0074] In this embodiment, the pressure sensor in the integrated device is named as the first pressure sensor 9 , and the first pressure sensor 9 is used to detect the pressure of the coolant entering the cylinder 1 from the liquid inlet pipe 3 .

[0075] In this embodiment, see Figure 1 As shown, the first pressure sensor 9, the expansion tank joint 11 and the liquid return joint 701 are arranged at intervals along the circumference of the cylinder 1. Exemplarily, the first pressure sensor 9, the expansion tank joint 11 and the liquid return joint 701 are arranged at intervals of 90° along the circumference of the cylinder 1, and the first pressure sensor is located between the expansion tank joint and the liquid return joint along the circumference to improve space utilization, and at the same time, it can also ensure that the parts of various functional parts inside the cylinder will not interfere with each other.

[0076] In one embodiment, the functional part further includes an air release device 10 , which is located on the circumferential side wall of the cylinder 1 , and is installed at the highest point of the cylinder 1 .

[0077] In actual use, the air venting device 10 should be at the highest point of the system. When the integrated device provided in this embodiment is applied to an air conditioning water system, the highest position of the cylinder 1 should be ensured to be the highest point of the system.

[0078] Exemplarily, the venting device 10 is a venting valve, and the function of the venting valve is to discharge the gas in the system to ensure that the system is in a full liquid state.

[0079] Conventional deflation valves need to be installed on a base, so the pipeline needs to be lengthened to leave room for welding the base. However, in this embodiment, the deflation valve is integrated on the circumferential side wall 103 of the cylinder 1, eliminating the need for installing the base and the tee, further shortening the length of the pipeline.

[0080] Since the air release device 10 and the first pressure sensor 9 occupy a relatively small space, in the present embodiment, the air release device 10 and the first pressure sensor 9 are arranged on the same side of the cylinder 1, that is, the first pressure sensor 9 is also arranged at the highest position of the cylinder, and the first pressure sensor 9 and the air release device 10 are spaced apart along the axial direction of the cylinder 1 to make full use of the space.

[0081] In one embodiment, the integrated device also includes a bracket 12, which is located on the circumferential side wall of the cylinder 1 and installed on the bottom of the cylinder 1. The bracket 12 includes two support plates 1201. The support plates 1201 are provided with folded edges, and the folded edges are provided with mounting holes for installing the support plates 1201 at a set position of the air-conditioning system through fasteners such as bolts.

[0082] By providing the bracket 12, it is not only convenient to install and fix the cylinder 1, but also convenient to adjust the height of the cylinder 1, so as to ensure that the highest position of the cylinder 1 is the highest point of the system.

[0083] The deflation device 10 and the bracket 12 are arranged opposite to each other along the height direction of the cylinder 1. In this embodiment, the deflation device 10 and the bracket 12 are arranged opposite to each other along the radial direction of the cylinder 1. Along the circumference of the cylinder 1, the liquid return joint 701, the expansion tank joint 11, the deflation device 10 and the bracket 12 are respectively located in different directions of the cylinder 1, which can further improve the space utilization rate, and at the same time, it can also ensure that the parts of the various functional parts inside the cylinder will not interfere with each other, and ensure that the parts of the various functional parts outside the cylinder will not interfere with each other.

[0084] The present embodiment further provides an air conditioning system, comprising the integrated device provided in the present embodiment, wherein the functional parts include at least one of a liquid return connector, a pressure sensor, an expansion tank connector, an air venting device, a liquid replenishing device and a temperature sensor.

[0085] The air conditioning system provided in this embodiment uses the integrated device provided in this embodiment, so the filter device 2 and at least one functional component do not need to be arranged at intervals along the length direction of the pipeline, thereby shortening the length of the water system and reducing resistance loss.

The air conditioning system provided in this embodiment also includes a pump body 13 and a condenser 14. The inlet of the pump body 13 is connected to the liquid outlet 1021 of the barrel 1, and the outlet of the pump body 13 is connected to the condenser 14. The high-temperature coolant enters the filter device 2 from the liquid inlet 1011, and the filtered coolant enters the pump body 13 from the liquid outlet 1021. The pump body 13 is sent to the condenser 14 of the air conditioning system for cooling, and the cooled coolant can be recycled.

[0093] In one embodiment, see Figure 7 As shown, the air conditioning system also includes a liquid return container 18, a liquid return pump 19 and a safety valve 20. The safety valve 20 is arranged on the condensing circuit of the air conditioning system. The inlet of the liquid return container 18 is connected to the safety valve 20, the outlet of the liquid return container 18 is connected to the inlet of the liquid return pump 19, and the outlet of the liquid return pump 19 is connected to the liquid return joint 701.

[0094] In one embodiment, a flow meter 21 is further provided on the condensing circuit of the air conditioning system for detecting the flow rate of the cooling liquid after the temperature is reduced.

[0095] In one embodiment, the air conditioning system further includes a fan 22 for exchanging heat between the coolant and the air. Exemplarily, the fan 22 is a variable frequency fan.

[0096] The working principle of the air conditioning system provided in this embodiment for cooling the battery will be described in detail below.

[0097] After the coolant cools the battery, its temperature rises. The heated coolant enters the filter device 2 through the liquid inlet quick connector 23 and the liquid inlet pipe 3, and then enters the condenser 14 through the pump body 13. The condenser 14 cools the coolant, and the heat generated by the cooling is discharged through the fan 22. The cooled coolant enters the battery cooling system through the liquid outlet quick connector to cool the battery, so that the battery is cooled. The temperature of the coolant rises and enters the air-conditioning system provided in this embodiment again to cool down. This cycle is repeated to achieve cyclic cooling of the battery.

[0098] In the above process, the first temperature sensor 8 is used to detect the temperature of the coolant before entering the condenser 14. Usually, the first temperature sensor 8 detects the temperature of the coolant entering the barrel 1 from the liquid inlet pipe 3. The first pressure sensor 9 is used to detect the pressure of the coolant entering the barrel 1 from the liquid inlet pipe 3.

[0099] When the pressure in the system is lower than the pressure in the expansion tank 17 , the expansion tank 17 replenishes the coolant into the system.

[0100] The filtering device 2 is used to filter the cooling liquid entering the cylinder 1 from the liquid inlet pipe 3 .

[0101] The second temperature sensor 16 is used to detect the temperature of the coolant after cooling by the condenser 14. When the second temperature sensor 16 detects that the temperature is higher than the target temperature of the coolant, the fan 22 needs to be turned on to further cool the coolant to reach the target temperature.

[0102] When the value of the second pressure sensor 15 minus the value of the first pressure sensor 9 is less than 0.15 bar, it indicates that the water flow in the system is insufficient and the system alarms. When the coolant in the system decreases, the water replenishing device replenishes water into the cylinder 1.

[0103] When the second pressure sensor 15 detects that the pressure is too high, the safety valve 20 automatically opens, allowing a portion of the coolant to enter the liquid return container 18 and be sent to the cylinder 1 through the liquid return pump 19 and the liquid return check valve 702, thereby avoiding excessive pressure in the system and improving safety.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
