[0052] An embodiment of the present invention provides a spliced ​​cabinet temperature control system, which is applied in outdoor scenarios and can store heat-generating units such as communication equipment units. By improving the structure of the spliced ​​cabinet temperature control system, it has the characteristics of high sealing on the basis of excellent expansion capability, thereby preventing rain from affecting the spliced ​​cabinet temperature control system.

[0053] like Figures 1 to 6 As shown, the spliced ​​cabinet temperature control system provided in this embodiment includes at least two cabinet units and a top card plate 2, and a top connection portion is protruded upward from the top of the cabinet unit. Among them, the cabinet unit can be an air conditioning unit 1, or an equipment cabinet unit 3, and the top card plate 2 can connect the air conditioning unit 1 and the equipment cabinet unit 3, or connect two air conditioning units 1, or connect two equipment cabinet units 3, without specific limitation.

[0054] A receiving groove 21 is provided at the bottom of the top card plate 2 , and the two abutting top connecting parts of the two cabinet units are both inserted into the receiving groove 21 , so that the gap between the two abutting top connecting parts is covered by the top card plate 2 .

[0055] A mounting groove is also provided at the bottom of the cabinet unit, and a bottom connecting portion is provided in the mounting groove. The two bottom connecting portions of the two cabinet units abutting against each other are detachably fixedly connected.

[0056] A sealing plate 42 is detachably installed in the installation groove, and a locking device is provided between the sealing plate 42 and the groove wall of the installation groove, and the locking device is used to limit the position between the sealing plate 42 and the cabinet unit.

[0057] Specifically, when assembling or expanding, the two cabinet units are connected. The specific installation process is: first, the two cabinet units are offset against each other, and the top connection part on one cabinet unit is connected to the top connection part on the other cabinet unit through the top card plate 2, so that the accommodating groove 21 wraps the above-mentioned two top connection parts located in different cabinet units but arranged adjacently, and the top installation of the spliced ​​cabinet temperature control system is completed; wherein, since the two top connection parts are engaged in the accommodating groove, the gap between the two top connection parts is covered by the top card plate 2, and at this time, rainwater cannot overcome gravity and flow from the groove wall of the accommodating groove 21 to the two top The gap between the connecting parts is formed, thereby preventing rainwater from entering the cabinet temperature control system from the gap between the two cabinet units; then, the bottom connecting part of one of the cabinet units is connected to the bottom connecting part on the other cabinet unit, and a sealing plate is installed in the respective installation grooves through a locking device, and then the locking device plays a role in fixing the sealing plate and the cabinet unit. The locking device can only be unlocked from the cabinet unit. Therefore, under the premise that the cabinet door of the cabinet unit is locked, outsiders cannot remove the sealing plate from the outside; therefore, the spliced ​​cabinet temperature control system of the present invention not only avoids the intrusion of rainwater but also avoids theft by outsiders, thereby improving safety.

[0058] Furthermore, the cabinet unit includes an air-conditioning unit 1 and an equipment cabinet unit 3; that is, for a single cabinet unit, the air-conditioning unit 1 or the equipment cabinet unit 3 can be selected according to actual needs, and the connection between the two cabinet units can refer to the connection between the air-conditioning unit 1 and the equipment cabinet unit 3, the connection between two air-conditioning units 1, and the connection between two equipment cabinet units 3.

[0059] The top connection part includes a first top connection part 11 and a second top connection part 31. The first top connection part 11 protrudes upward from the top wall of the air-conditioning unit 1 and is arranged at both ends of the air-conditioning unit 1; the second top connection part 31 protrudes upward from the top wall of the equipment cabinet unit 3 and is arranged at both ends of the equipment cabinet unit 3.

[0060] Exemplarily, the top wall of the air conditioning unit 1 in this embodiment is provided with a first top connecting portion 11 at both ends; therefore, when the number of communication equipment units is small, such as Figure 2 As shown, the equipment cabinet unit 3 can be installed on the right side of the air conditioning unit 1; or Figure 3 As shown, the equipment cabinet unit 3 can be installed on the left side of the air conditioning unit 1; when expansion is required, Figure 4 As shown, an equipment cabinet unit 3 is correspondingly installed on the other side of the air conditioning unit 1, thereby increasing the equipment storage quantity of the spliced ​​cabinet temperature control system.

[0061] During assembly or expansion, firstly, the equipment cabinet unit 3 is abutted against the air conditioning unit 1, so that the first top connection part 11 and the second top connection part 31 are abutted against each other, and then the two ends of the top card plate 2 are fixedly connected to the first top connection part 11 and the second top connection part 31 respectively, so that the receiving groove 21 wraps the first top connection part 11 and the second top connection part 31, and the assembly or expansion of the spliced ​​cabinet temperature control system is completed. Among them, since the first top connection part 11 and the second top connection part 31 are engaged in the receiving groove 21, the gap between the first top connection part 11 and the second top connection part 31 is covered by the top card plate 2. At this time, rainwater cannot overcome gravity and flow from the groove wall of the receiving groove 21 to the gap between the first top connection part 11 and the second top connection part 31, thereby preventing rainwater from entering the cabinet temperature control system from the gap between the air conditioning unit 1 and the equipment cabinet unit 3, eliminating the safety hazards caused by the expansion of the cabinet temperature control system.

[0062] Exemplarily, the second top connecting parts 31 are protrudingly provided at both ends of the top wall of the equipment cabinet unit 3 , and the second bottom connecting parts 32 are provided at both ends of the bottom of the equipment cabinet unit 3 .

[0063] When two adjacent equipment cabinet units 3 are connected, two adjacent second top connecting parts 31 are fixedly connected through the top clamping plate 2 , and two adjacent second bottom connecting parts 32 are fixedly connected.

[0064] Specifically, according to the site requirements or the number of communication equipment required, multiple equipment cabinet units 3 can be installed on the same side of the air-conditioning unit 1, and the adjacent equipment cabinet units 3 are connected in the same manner as described above, with the only difference being that the adjacent equipment cabinet units 3 are fixedly connected by two second top connecting parts 31, and the technical effect of improving the sealing is achieved by wrapping the two second top connecting parts 31 with the top card plate 2.

[0065] Furthermore, if Fig.10 and Fig.11 As shown, the mounting groove includes a first mounting groove 13 and a second mounting groove 33, and the bottom connection part includes a first bottom connection part 12 and a second bottom connection part 32; the first mounting groove 13 is opened at the bottom of the air-conditioning unit 1, and the second mounting groove 33 is opened at the bottom of the equipment cabinet unit 3; the first bottom connection part 12 is formed on the groove wall of the first mounting groove 13; the second bottom connection part 32 is formed on the groove wall of the second mounting groove 33.

[0066] Exemplarily, when the equipment cabinet unit 3 is connected to the air conditioning unit 1, the first bottom connection part 12 is fixedly connected to the second bottom connection part 32. It should be noted that the first bottom connection part 12 and the second bottom connection part 32 play the role of auxiliary connection, and the safety of the spliced ​​cabinet temperature control system is further improved through the connection of the first bottom connection part 12 and the second bottom connection part 32.

[0067] In a specific embodiment, a first mounting groove 13 is formed in the air conditioning unit 1, and a first bottom connecting portion 12 is formed on a groove wall of the first mounting groove 13, and the first bottom connecting portion 12 includes a first mounting hole.

[0068] A second installation groove 33 is formed in the equipment cabinet unit 3 . A second bottom connecting portion 32 is formed on a groove wall of the second installation groove 33 . The second bottom connecting portion 32 includes a second installation hole.

[0069] When the equipment cabinet unit 3 is connected to the air conditioning unit 1, the first mounting hole and the second mounting hole are fixedly connected by bolts. This installation method is simple to operate and ensures the connection stability between the equipment cabinet unit 3 and the air conditioning unit 1; and the first bottom connecting part 12 and the second bottom connecting part 32 arranged inside are highly concealed and do not protrude from the appearance surface of the unit, and the integration is higher.

[0070] It should be supplemented that the equipment cabinet unit 3 and the air-conditioning unit 1 can also be fixedly connected at the bottom by other means; for example, the first bottom connecting part 12 is a card slot opened on the slot wall of the first mounting slot 13, and the second bottom connecting part 32 is a protrusion protruding from the second mounting slot 33. When the equipment cabinet unit 3 is connected to the air-conditioning unit 1, the protrusion passes through the card slot, and a pin hole is opened on the protrusion, and a pin can be passed through the pin hole to complete the connection between the equipment cabinet unit 3 and the air-conditioning unit 1; or without opening a mounting slot, the first bottom connecting part 12 and the second bottom connecting part 32 are respectively arranged on the outside of the unit, the first bottom connecting part 12 and the second bottom connecting part 32 are respectively opened with lock holes, and the first bottom connecting part 12 and the second bottom connecting part 32 are locked by additional locks, which will make it convenient for staff to operate from the outside.

[0071] Furthermore, if Figures 7 to 9 As shown, the locking device includes a locking rod 41, and the locking rod 41 can slide in the installation groove along the vertical direction.

[0072] A locking rod 41 which can slide in the vertical direction is disposed in both the first installation groove 13 and the second installation groove 33 .

[0073] The air conditioning unit 1 and the equipment cabinet unit 3 are both detachably connected with a sealing plate 42 . A clamping portion 43 is protruded from the sealing plate 42 . A clamping groove 44 is formed at the position of the clamping portion 43 corresponding to the locking rod 41 .

[0074] When the sealing plate 42 is engaged with the mounting groove, that is, when the sealing plate 42 is engaged with the first mounting groove 13 and / or the second mounting groove 33 , the locking rod 41 is engaged in the engaging groove 44 .

[0075] Among them, it is necessary to understand that after the first bottom connecting part 12 and the second bottom connecting part 32 are fixedly connected, the locking part 43 of the sealing plate 42 is locked with the locking rod 41 through the locking groove 44, so that the splicing cabinet temperature control system has strong sealing and high safety. After the sealing plate 42 is installed, it cannot be directly taken out from the outside of the splicing cabinet temperature control system. The sealing plate 42 can only be removed by opening the cabinet door of the splicing cabinet temperature control system and releasing the lock of the locking rod 41 and the locking groove 44 from the inside.

[0076] In a specific embodiment, a guide portion 45 is formed at one end of the engaging portion 43 away from the sealing plate 42. Along the direction away from the sealing plate 42, the width of the guide portion 45 in the vertical direction decreases.

[0077] Exemplarily, when installing the sealing plate 42, the sealing plate 42 is pushed into the installation groove, and the locking rod 41 first contacts the guide portion 45, and gradually rises under the action of the guide portion 45 until the locking groove 44 is located below the locking rod 41. Since the locking groove 44 is lower than the highest point of the guide portion 45, the locking rod 41 falls into the locking groove 44; at this time, the locking rod 41 cannot be removed from the locking groove 44 from the outside, and the sealing plate 42 is almost impossible to be removed from the outside, so that the safety of the spliced ​​cabinet temperature control system is further improved.

[0078] It should be added that an elastic portion is formed at one end of the locking portion 43 away from the sealing plate 42, and the elastic portion is the groove wall of the locking groove 44 away from the sealing plate 42; exemplarily, when installing the sealing plate 42, the sealing plate 42 is pushed into the installation groove, and the locking rod 41 first contacts the elastic portion, causing the elastic portion to move downward until the locking rod 41 enters the locking groove 44. At this time, the elastic portion is reset to serve as the groove wall of the locking groove 44 to limit the locking rod 41.

[0079] Furthermore, hook portions 46 are provided in both the first installation groove 13 and the second installation groove 33, and a sliding portion 47 with a sliding groove is provided at both ends of the hook portion 46. The hook portion 46 assists the staff in lifting the locking rod 41 to unlock the locking of the locking rod 41 and the engaging groove 44. When the sealing plate needs to be removed, the staff can lift the hook portion 46 from the inside to move the locking rod 41 away from the engaging groove 44, thereby releasing the locking of the locking rod 41 and the engaging groove 44.

[0080] The rod portion of the locking rod 41 is supported on the hook portion 46, and the end of the locking rod 41 is slidably connected to the slide groove of the sliding portion 47. It should be noted that the sliding portion 47 serves to limit the movement direction of the locking rod 41 to prevent the locking rod 41 from being displaced; and the hook portion 46 serves to balance the force. In particular, two engaging portions 43 are convexly provided on the sealing plate 42, and the two engaging portions 43 are respectively located on both sides of the hook portion 46. When the guide portion 45 initially contacts the locking rod 41, the hook portion 46 serves to balance the force at both ends, preventing the locking rod 41 from moving up at one end and moving down at the other end, thereby improving the stability of the sealing plate 42 during installation.

[0081] In another specific embodiment, the locking device includes a first connector, one end of which is fixed to the inner side of the sealing plate 42, and the other end of the first connector is provided with a fixing hole and can be inserted into the installation groove; a second connector is provided in the installation groove and is fixedly connected to the first connector through the fixing hole. Exemplarily, the first connector is an L-shaped connector, one end of which is provided with a fixing hole and can be inserted into the installation groove, and the second connector provided in the installation groove can be provided with a fixing hole. At this time, the staff can connect the first connector and the second connector by bolts or screws on the inner side of the cabinet unit to complete the installation of the sealing plate 42; in addition, a sliding block can be slidably installed in the installation groove, and the first connector and the second connector are fixedly connected by the sliding block passing through the fixing holes on the first connector and the second connector respectively, thereby completing the installation of the sealing plate 42.

[0082] Furthermore, a connecting plate is fixedly connected to the cabinet unit; the connecting plate is used to fix two adjacent cabinets. For example, two adjacent equipment cabinet units 3 are each installed with a connecting plate, wherein the connecting plate is arranged on the cabinet wall of the equipment cabinet unit 3, and bolt holes are formed on the connecting plate. The adjacent equipment cabinet units 3 can be fixedly connected to the two connecting plates by bolts to achieve further locking of the equipment cabinet units 3.

[0083] Furthermore, if Fig.12 As shown, the air conditioning unit 1 further includes an evaporation-side cavity 51 and a condensation-side cavity 52 .

[0084] The cavity wall of the evaporation side cavity 51 is provided with an evaporation side return air port 53 and an evaporation side supply air port 54 , and the equipment installation station in the equipment cabinet unit 3 is arranged between the evaporation side return air port 53 and the evaporation side supply air port 54 .

[0085] More specifically, a heat absorbing refrigeration heat exchange device 71 is provided in the evaporation side cavity 51, and a heat releasing heat exchange device 72 is provided in the condensation side cavity 52, and the heat releasing heat exchange device 72 is connected to the heat absorbing refrigeration heat exchange device 71 through a refrigerant pipeline. The heat absorbing refrigeration heat exchange device 71 cools the hot air to obtain cold air through the refrigerant flowing inside it, and the heated refrigerant flows to the heat releasing heat exchange device 72, and the heat releasing heat exchange device 72 cools the heated refrigerant through an outdoor cold source, and the refrigerant flows to the heat absorbing refrigeration heat exchange device 71 after cooling.

[0086] The evaporation side cavity 51 includes a first cavity wall and a second cavity wall arranged opposite to each other along a first direction, and at least one group of evaporation air outlets are respectively provided on the first cavity wall and the second cavity wall, and the evaporation air outlets include an evaporation side return air outlet 53 and an evaporation side supply air outlet 54 opened along the first direction, and the airflow between the evaporation side supply air outlet 54 and the evaporation side return air outlet 53 flows through the equipment cabinet unit 3. The first direction is Fig.12 The marked direction in is also the arrangement direction of the equipment cabinet unit 3, that is, when multiple equipment cabinet units 3 are provided, the equipment cabinet units 3 are distributed along the first direction.

[0087] A condensation side return air port 55 and a condensation side air outlet 56 are provided on the cavity wall of the condensation side cavity 52 along the second direction. It should also be noted that the air conditioning unit 1 of this embodiment adopts a layout in which the condensation side cavity 52 and the evaporation side cavity 51 are distributed from top to bottom. At this time, the equipment cabinet unit 3 can be arranged on one side or both sides of the left and right sides of the evaporation side cavity 51 along the first direction, leaving the condensation side return air port 55 and the condensation side air outlet 56 to exchange heat with the air outside the cabinet in the second direction. The condensation side and the evaporation side do not interfere with each other, the heat exchange efficiency is high, and the overall footprint of the air conditioning unit 1 is small, which is convenient for site selection and transportation.

[0088] Specifically, the spliced ​​cabinet temperature control system of this embodiment improves the structure of the air-conditioning unit 1 so that the first cavity wall and the second cavity wall respectively have an evaporation side return air port 53 and an evaporation side supply air port 54 opened along the first direction, and also have a condensation side return air port 55 and a condensation side outlet port 56 opened along the second direction on the cavity wall of the condensation side cavity 52; firstly, the evaporation side cavity 51 and the condensation side cavity 52 are independent of each other, and the inlet and outlet air of the evaporation side and the condensation side will not interfere with each other, and the air-conditioning unit 1 integrates the evaporation side and the condensation side into one, occupies less space, and is easy to move, so that the air-conditioning unit 1 can be quickly dragged and is easy to install on site; then, since at least one group of evaporation air ports are respectively opened on the first cavity wall and the second cavity wall, the equipment cabinet unit 3 can be set individually on one side of the air-conditioning unit 1, or two can be set and installed on both sides of the air-conditioning unit 1 respectively, and the capacity expansion can be completed by connecting the equipment cabinet unit 3 to the air-conditioning unit 1, that is, the capacity expansion flexibility of the equipment cabinet unit 3 is high.

[0089] Furthermore, a condensing fan 74 is installed in the condensing side cavity 52 between the heat release heat exchange device 72 and the condensing side air outlet 56, and the air outlet direction of the condensing fan 74 is the same as the second direction.

[0090] An evaporation fan 73 is also installed in the evaporation side cavity 51 between the heat absorption refrigeration heat exchange device 71 and the evaporation side air outlet 54, and the air outlet direction of the evaporation fan 73 is the same as the first direction. Among them, the condensation fan 74 and the evaporation fan 73 are both centrifugal fans with large air volume, which can meet the efficient circulation of heat exchange airflow in the cabinet. It should be understood that both the evaporator fan 73 and the condenser fan 74 play a role in changing direction. For example, after the indoor hot air enters the evaporator side cavity 51 through the evaporator side return air port 53, it passes through the heat absorption and cooling heat exchange device 71, and then passes through the evaporator fan 73 to turn and increase the air volume, and finally is discharged from the evaporator side supply air port 54. Among them, the hot air flows along the second direction after entering the evaporator side cavity 51. The evaporator fan 73 also plays a role in correcting the wind direction of the indoor cold air that is cooled, so that the indoor cold air finally flows out of the evaporator side cavity 51 along the first direction to ensure the circulation and high efficiency of the air flow; similarly, the condenser fan 74 also plays a role in correcting the outdoor hot air after heating, so that the outdoor hot air finally flows out of the condenser side cavity 52 along the second direction; in the limited space of the air-conditioning unit 1, the flow length of the wind in the evaporator side cavity 51 and the condenser side cavity 52 is extended, so as to maximize the heat exchange effect between the indoor air and the heat absorption and cooling heat exchange device 71, and to improve the heat exchange effect between the outdoor air and the heat release heat exchange device 72.

[0091] Furthermore, if Fig.13 As shown, sliding pins 61 are slidably connected at positions corresponding to the evaporation side return air outlet 53 and the evaporation side supply air outlet 54 in the evaporation side cavity 51 .

[0092] The evaporation side return air outlet 53 and the evaporation side supply air outlet 54 are respectively detachably connected with a baffle 62, and the baffle 62 is protruding with an ear plate 63, and the ear plate 63 is provided with a pin hole 64; the sliding pin 61 is used to lock the baffle 62 with the air conditioning unit 1. It should be added that a pull rope can be connected to one end of the sliding pin 61 to facilitate the staff to release the locking of the baffle 62 by the sliding pin 61, and a guiding inclined surface is formed on one end of the sliding pin 61, and a compression spring is sleeved on the other end of the sliding pin 61, one end of the compression spring abuts against the evaporation side cavity 51, and the other end of the compression spring abuts against the other end of the sliding pin 61.

[0093] When the baffle 62 is set on the evaporation side return air outlet 53 or the evaporation side air supply outlet 54, the staff can press the baffle 62 toward the evaporation side return air outlet 53 or the evaporation side air supply outlet 54 from the outside, and the ear plate 63 squeezes the guiding inclined surface of the sliding pin 61 to compress the compression spring until the position of the pin hole 64 coincides with the position of the sliding pin 61, and the ear plate 63 no longer squeezes the sliding pin 61, so that the sliding pin 61 slides into the pin hole 64 under the action of the compression spring, and the sliding pin 61 is used to lock the position relationship between the baffle 62 and the evaporation side cavity 51, so that the staff can only pull the pull rope from the inside of the evaporation side cavity 51 to release the lock of the sliding pin 61 on the baffle 62, which is equivalent to the sliding pin 61 limiting the position relationship between the baffle 62 and the evaporation side cavity 51, so that outsiders cannot disassemble the sealing device from the outside of the air-conditioning unit 1, thereby improving the stability and safety of the spliced ​​cabinet temperature control system.

[0094] In summary, the spliced ​​cabinet temperature control system provided in this embodiment has expansion capability and strong waterproof sealing. It also has the advantages of high stability, high safety, and efficient heat exchange airflow.
