Description

Technical Field

[0001] The present disclosure relates to the field of heat dissipation technologies, and particularly to a temperature control unit and a measuring probe mounting mechanism. Background Art

[0002] Data centers generally dissipate heat through temperature control units. The temperature control unit includes a fan and a heat exchanger. The fan is used to suck air and blow the air towards the air inlet side of the heat exchanger. After the air is cooled by the heat exchanger, it is blown out from the air outlet side of the heat exchanger and blown into the computer room of the data center.

[0003] In order to monitor the operating state of the temperature control unit in real time, it is necessary to monitor information such as the temperature, humidity or air pressure on the air outlet side of the heat exchanger. Summary of the Utility Model

[0004] The present disclosure provides a temperature control unit and a measuring probe mounting mechanism. The measuring probe in the temperature control unit is arranged on the air outlet side of the heat exchanger through the measuring probe mounting mechanism. Moreover, maintenance personnel can operate the measuring probe mounting mechanism in the maintenance space to realize the disassembly and assembly of the measuring probe. The technical solutions of the temperature control unit and the measuring probe mounting mechanism are as follows.

[0005] In a first aspect, the present disclosure provides a temperature control unit. The temperature control unit includes a housing, a fan, a heat exchanger, a measuring probe mounting mechanism and a measuring probe. The fan and the heat exchanger are located inside the housing, and there is a maintenance space between the fan and the air inlet side of the heat exchanger. The housing has a partition portion adjacent to the heat exchanger, which separates the maintenance space from the air outlet space of the heat exchanger. The partition portion has a through hole. The measuring probe mounting mechanism includes a first rod and a second rod. The first end of the first rod is fixed to the partition portion and passes through the through hole. The second end of the first rod is located in the air outlet space and is rotatably connected to one end of the second rod. The second rod is bent relative to the first rod, and the second rod is located on the air outlet side of the heat exchanger. The measuring probe is fixed to the second rod.

[0006] Wherein, the temperature control unit includes a wind wall or an indirect evaporative cooling unit, etc. The housing is used to support and protect the fan and the heat exchanger. In a possible implementation manner, the housing includes a column body and a plate body, and the column body supports the plate body. In a possible implementation manner, the heat exchanger is fixed on the column body, and the column body forms the partition portion. After the partition portion separates the maintenance space and the air outlet space, it can prevent the air blown out from the air outlet space from flowing back into the maintenance space.

[0007] The measuring probe mounting mechanism includes a first rod and a second rod, and the first rod and the second rod can be switched between a bent state and an unfolded state by relative rotation. Among them, when the measuring probe is working normally, the measuring probe mounting mechanism is in the bent state, the second rod is bent relative to the first rod, and the second rod and the measuring probe are located on the air outlet side of the heat exchanger. When it is necessary to disassemble and assemble the measuring probe, the measuring probe mounting mechanism is switched from the bent state to the unfolded state, and then the maintenance personnel can push the measuring probe mounting mechanism into the air outlet space or pull the measuring probe mounting mechanism out of the air outlet space through the through hole on the partition part. In a possible implementation manner, in the bent state, the first rod and the second rod are perpendicular or approximately perpendicular. For example, the included angle between the first rod and the second rod is greater than 70° and less than 110°. In a possible implementation manner, in the unfolded state, the first rod and the second rod are coaxial or approximately coaxial. For example, the included angle between the first rod and the second rod is greater than 170° and less than or equal to 180°.

[0008] In the technical solution provided by the present disclosure, when the measuring probe is in the normal working state, the measuring probe mounting mechanism is in the bent state, and the second rod is located on the air outlet side of the heat exchanger, so that the measuring probe is located on the air outlet side of the heat exchanger, and then the measuring probe can measure information such as temperature, humidity or air pressure on the air outlet side of the heat exchanger.

[0009] When it is necessary to disassemble the measuring probe, the maintenance personnel operate the measuring probe mounting mechanism to switch the measuring probe mounting mechanism from the bent state to the unfolded state. Then, the maintenance personnel drag the measuring probe mounting mechanism from the air outlet space into the maintenance space through the through hole on the partition part. Finally, the maintenance personnel disassemble the measuring probe from the measuring probe mounting mechanism and repair or replace the measuring probe.

[0010] When it is necessary to reinstall the measuring probe, the maintenance personnel operate the measuring probe mounting mechanism to remain in the unfolded state. Then, the maintenance personnel extend the measuring probe mounting mechanism into the air outlet space through the through hole on the partition part. Finally, the maintenance personnel operate the measuring probe mounting mechanism to switch from the unfolded state to the bent state, and then the second rod drives the measuring probe to rotate to the air outlet side of the heat exchanger, and the measuring probe can measure information such as temperature, humidity or air pressure on the air outlet side of the heat exchanger again.

[0011] It can be seen that the technical solution provided by the present disclosure not only arranges the measuring probe on the air outlet side of the heat exchanger, but also when it is necessary to maintain the measuring probe, the maintenance personnel can disassemble the measuring probe in the maintenance space. After the disassembly is completed, the maintenance personnel can also install the measuring probe in the maintenance space. The maintenance personnel do not need to enter the cold air duct, which simplifies the operation of the maintenance personnel.

[0012] In a possible implementation, the second rod includes a third end and a fourth end, the third end of the second rod is rotatably connected to the second end of the first rod, and the measuring probe is fixed to the fourth end of the second rod.

[0013] In a possible implementation manner, the length A of the first rod is greater than 40 cm and less than 50 cm.

[0014] In a possible implementation, the length B of the second rod is greater than 40 cm and less than 60 cm.

[0015] In a possible implementation, the measuring probe mounting mechanism further includes a base, which is fixedly connected to the first end of the first rod; the base is located in the maintenance space and fixedly connected to the partition.

[0016] The technical solution provided by the present disclosure facilitates the fixation of the measuring probe installation mechanism and the partition part by providing a base.

[0017] In a possible implementation, the base has a threading hole, which is connected to the through hole. The measuring probe has a connecting wire, which passes through the threading hole and the through hole. In this way, the connecting wire of the measuring probe is convenient to extend from the air outlet space to the maintenance space.

[0018] In a possible implementation, the measuring probe has a connecting wire, and the connecting wire is fixed to the first rod and the second rod respectively. In this way, on the one hand, the connecting wire can be prevented from swinging freely in the air outlet space. On the other hand, the connecting wire can also limit the relative rotation of the first rod and the second rod, so that the first rod and the second rod can be kept in a bent state.

[0019] In a possible implementation, both the first rod and the second rod have a tie fixing groove. The measuring probe installation mechanism also includes a tie, which tightens the connecting wire and the first rod, and the connecting wire and the second rod, and the tie is located in the tie fixing groove.

[0020] The technical solution provided by the present disclosure facilitates the positioning of the cable tie by arranging cable tie fixing grooves on the first rod and the second rod.

[0021] In a possible implementation, the second end of the first rod has a first limiting structure, and the first limiting structure is located on the rotation path of the second rod. The first limiting structure is used to contact the second rod so that the second rod remains in a bent state relative to the first rod.

[0022] According to the technical solution provided by the present disclosure, after the first limiting structure contacts the second rod, the second rod cannot continue to rotate toward the first rod, so that the measuring probe installation mechanism can be kept in a bent state more stably.

[0023] In a possible implementation, when the first limiting structure contacts the second rod, the first rod is perpendicular to the second rod.

[0024] In a possible implementation, the housing further includes a blocking portion located in the air outlet space and opposite to the through hole of the partition portion. The distance between the partition portion and the blocking portion is d1, the length of the first rod is A, and the length of the second rod is B. Both A and B are less than d1. In this way, it can be ensured that both the first rod and the second rod can extend into the interior of the air outlet space without being blocked by the blocking portion.

[0025] In a possible implementation, the distance between the through hole of the partition portion and the bottom wall of the housing is H, and B is less than H. In this way, the measuring probe mounting mechanism can be enabled to achieve a state where the second rod rotates downward relative to the first rod.

[0026] In a possible implementation, the measuring probe mounting mechanism further includes a rotational damper. The first rod and the second rod are rotationally connected through the rotational damper. Among them, the presence of the rotational damper increases the force required to overcome the rotation of the first rod and the second rod, so that the first rod and the second rod will not rotate randomly due to reasons such as vibration.

[0027] In a possible implementation, the length of the first rod can be adjusted.

[0028] The technical solution provided by the present disclosure enables the measuring probe mounting mechanism to be applicable to heat exchangers of different thicknesses by setting that the length of the first rod can be adjusted, thereby improving the applicability of the measuring probe mounting mechanism. Among them, the thickness direction of the heat exchanger is the same as the blowing direction of the fan.

[0029] In a possible implementation, the first rod includes a first inner rod, a first outer rod, a first elastic member, and a first positioning member. The side portion of the first inner rod has a first opening. The first elastic member and the first positioning member are located in the first opening, and the first elastic member drives a part of the first positioning member to extend out of the first opening. The first outer rod has a plurality of first positioning holes arranged along the length direction. The first outer rod sleeves the first inner rod, and the first positioning member extends into one of the first positioning holes. By adjusting the first positioning hole into which the first positioning member extends, the length of the first rod can be adjusted.

[0030] For the technical solution provided by the present disclosure, when the length of the first rod needs to be adjusted, first, press the first positioning member so that the first positioning member disengages from the first positioning hole. Then, slide the first inner rod until the first positioning member aligns with another first positioning hole. Finally, under the action of the elastic force of the first elastic member, the first positioning member extends into another first positioning hole, and the length adjustment of the first rod is completed.

[0031] In a possible implementation, the length of the second rod can be adjusted.

[0032] The technical solution provided by the present disclosure enables the length of the second rod to be adjustable, so that the measuring probe mounting mechanism can be applicable to heat exchangers of different lengths, improving the applicability of the measuring probe mounting mechanism. Among them, the length direction of the heat exchanger is perpendicular to both the height direction and the thickness direction of the heat exchanger.

[0033] In a possible implementation manner, the second rod includes a second inner rod, a second outer rod, a second elastic member, and a second positioning member. The side of the second inner rod has a second opening, the second elastic member and the second positioning member are located in the second opening, and the second elastic member drives a part of the second positioning member to protrude from the second opening. The second outer rod has a plurality of second positioning holes arranged along the length direction. The second outer rod sleevingly surrounds the first inner rod, the second positioning member extends into one of the second positioning holes, and the length of the second rod can be adjusted by adjusting the second positioning hole into which the second positioning member extends.

[0034] For the technical solution provided by the present disclosure, when it is necessary to adjust the length of the second rod, first, press the second positioning member so that the second positioning member disengages from the second positioning hole. Then, slide the second inner rod until the second positioning member aligns with another second positioning hole. Finally, under the action of the elastic force of the second elastic member, the second positioning member extends into another second positioning hole, and the length adjustment of the second rod is completed.

[0035] In a second aspect, the present disclosure provides a measuring probe mounting mechanism. The measuring probe mounting mechanism includes a first rod and a second rod. The first end of the first rod is used to pass through the through hole of the partition of the temperature control unit, the second end of the first rod is located in the air outlet space of the temperature control unit, and is rotatably connected to one end of the second rod. Among them, the partition is adjacent to the heat exchanger of the temperature control unit and separates the maintenance space and the air outlet space of the temperature control unit. The second rod is used to fix the measuring probe. Description of the Drawings

[0066] Data centers generally need to dissipate heat through a temperature control unit 1. As Figure 1 shown, an embodiment of the present disclosure provides a schematic diagram of a data center. The data center includes a temperature control unit 1, a machine room 2, a temperature control unit room 3, a cold air duct 4, and a hot air duct 5. The temperature control unit 1 is located in the temperature control unit room 3. There is electronic equipment 21 in the machine room 2, and the electronic equipment 21 generates heat when working. The hot air duct 5 is located above the machine room 2 and communicates with the temperature control unit room 3. The air outlet side of the temperature control unit 1 is connected to the inside of the machine room 2 through the cold air duct 4.

[0067] When the temperature control unit 1 is operating, the temperature control unit 1 inputs cold air into the interior of the computer room 2 through the cold air duct 4. After the cold air is heated by the electronic equipment 21, it becomes hot air and flows into the hot air duct 5. Then, the hot air flows from the hot air duct 5 into the temperature control unit room 3. After the temperature control unit 1 cools the hot air, it inputs cold air into the interior of the computer room 2 through the cold air duct 4 again.

[0068] As Figure 2 shown, the temperature control unit 1 includes a housing 11, a fan 12 and a heat exchanger 13. The fan 12 and the heat exchanger 13 are located inside the housing 11, and there is a maintenance space 101 between the air inlet sides of the fan 12 and the heat exchanger 13. The housing 11 is provided with a maintenance door 1121, and maintenance personnel can enter and exit the maintenance space 101 through the maintenance door 1121.

[0069] In order to monitor the operating state of the temperature control unit 1 in real time, as Figure 1 and Figure 3 shown, it is necessary to set a measurement probe 15 on the air outlet side of the heat exchanger 13. The measurement probe 15 is used to measure the temperature, humidity, air pressure, etc. on the air outlet side of the heat exchanger 13. As Figure 3 shown, the measurement probe 15 has a connection line 151, and the connection line 151 extends into the maintenance space 101, so that maintenance personnel can obtain the measurement information of the measurement probe 15 in the maintenance space 101.

[0070] As Figure 1 and Figure 3 shown, in the related art, the measurement probe 15 is directly fixed to the air outlet side of the heat exchanger 13. When the temperature control unit 1 leaves the factory, the air outlet side of the heat exchanger 13 is not closed, so that the staff can easily fix the measurement probe 15 on the air outlet side of the heat exchanger 13.

[0071] However, when the temperature control unit 1 is applied to the data center, the air outlet space 102 of the temperature control unit 1 will be connected to the cold air duct 4, which makes it necessary for maintenance personnel to reach the air outlet side of the heat exchanger 13 through the end of the cold air duct 4. This not only increases the operation difficulty of maintenance personnel, but also requires a static pressure box to be set in the cold air duct 4 to facilitate the entry and exit of maintenance personnel from the cold air duct 4, increasing the cost of the data center. In addition, during the process of maintenance personnel entering and exiting the cold air duct 4, the cold air duct 4 may be deformed due to bearing weight.

[0072] In view of the above technical problems, the embodiments of the present disclosure provide a temperature control unit 1. The measurement probe 15 of the temperature control unit 1 is located on the air outlet side of the heat exchanger 13, and maintenance personnel can disassemble and assemble the measurement probe 15 in the maintenance space 101 without entering the cold air duct 4. In this way, the operation difficulty of maintenance personnel is reduced, the cost of the data center is lowered, and the reliability of the cold air duct 4 is improved. Next, an exemplary description of the temperature control unit 1 provided by the embodiments of the present disclosure will be given.

[0073] As shown Figures 4 - 7 in the figure, the temperature control unit 1 includes a housing 11, a fan 12, a heat exchanger 13, a measurement probe mounting mechanism 14, and a measurement probe 15. The fan 12 and the heat exchanger 13 are located inside the housing 11, and there is a maintenance space 101 between the air inlet sides of the fan 12 and the heat exchanger 13. The housing 11 has a partition 113, which is adjacent to the heat exchanger 13 and separates the maintenance space 101 from the air outlet space 102 of the heat exchanger 13. The partition 113 has a through hole 1130. The measurement probe mounting mechanism 14 includes a first rod 141 and a second rod 142. The first end of the first rod 141 is fixed to the partition 113 and passes through the through hole 1130. The second end of the first rod 141 is located in the air outlet space 102 and is rotatably connected to one end of the second rod 142. The second rod 142 is bent relative to the first rod 141 and is located on the air outlet side of the heat exchanger 13. The measurement probe 15 is fixed to the second rod 142.

[0074] Among them, the temperature control unit 1 includes a wind wall or an indirect evaporation cooling unit, etc. The housing 11 is used to support and protect the fan 12, the heat exchanger 13, etc. In some examples, the housing 11 includes a column 111 and a plate 112, and the column 111 supports the plate 112. In some examples, as Figure 4 shown in the figure, the heat exchanger 13 is fixed on the column 111, and the column 111 forms the partition 113. After the partition 113 separates the maintenance space 101 and the air outlet space 102, it can prevent the air blown out from the air outlet space 102 from flowing back into the maintenance space 101.

[0075] The measurement probe mounting mechanism 14 includes a first rod 141 and a second rod 142, and the first rod 141 and the second rod 142 can be switched between a bent state and an unfolded state through relative rotation. As Figures 4 - 7 shown in the figure, when the measurement probe 15 is working normally, the measurement probe mounting mechanism 14 is in a bent state, the second rod 142 is bent relative to the first rod 141, and the second rod 142 and the measurement probe 15 are located on the air outlet side of the heat exchanger 13. As Figure 8 shown in the figure, when it is necessary to disassemble and assemble the measurement probe 15, the measurement probe mounting mechanism 14 is switched from the bent state to the unfolded state, and then the maintenance personnel can push the measurement probe mounting mechanism 14 into the air outlet space 102 or pull the measurement probe mounting mechanism 14 out of the air outlet space 102 through the through hole 1130 on the partition 113. In some examples, in the bent state, the first rod 141 and the second rod 142 are perpendicular or approximately perpendicular. For example, the included angle between the first rod 141 and the second rod 142 is greater than 70° and less than 110°. In some examples, in the unfolded state, the first rod 141 and the second rod 142 are coaxial or approximately coaxial. For example, the included angle between the first rod 141 and the second rod 142 is greater than 170° and less than or equal to 180°.

[0076] In the technical solution provided by the embodiments of the present disclosure, when the measurement probe 15 is in a normal working state, the measurement probe mounting mechanism 14 is in a bent state, and the second rod 142 is located on the air outlet side of the heat exchanger 13, so that the measurement probe 15 is located on the air outlet side of the heat exchanger 13. Then, the measurement probe 15 can measure information such as the temperature, humidity, or air pressure on the air outlet side of the heat exchanger 13.

[0077] When it is necessary to disassemble the measurement probe 15, the maintenance personnel operate the measurement probe mounting mechanism 14, so that the measurement probe mounting mechanism 14 switches from the bent state to the unfolded state. Then, the maintenance personnel can drag the measurement probe mounting mechanism 14 from the air outlet space 102 into the maintenance space 101 through the through hole 1130 on the partition portion 113. After that, the maintenance personnel can repair or replace the measurement probe 15.

[0078] When it is necessary to reinstall the measurement probe 15, the maintenance personnel operate the measurement probe mounting mechanism 14 to remain in the unfolded state. Then, the maintenance personnel push the measurement probe mounting mechanism 14 into the air outlet space 102 through the through hole 1130 on the partition portion 113. Then, the maintenance personnel operate the measurement probe mounting mechanism 14 to switch from the unfolded state to the bent state. Then, the second rod 142 drives the measurement probe 15 to rotate to the air outlet side of the heat exchanger 13, and the measurement probe 15 can measure the temperature, humidity, or air pressure on the air outlet side of the heat exchanger 13 again.

[0079] In summary, the technical solution provided by the embodiments of the present disclosure not only provides the measurement probe 15 on the air outlet side of the heat exchanger 13, but also enables the maintenance personnel to disassemble the measurement probe 15 in the maintenance space 101 when maintenance of the measurement probe 15 is required. After the disassembly is completed, the maintenance personnel can also install the measurement probe 15 in the maintenance space 101. The maintenance personnel no longer need to enter the cold air duct 4, which reduces the operation difficulty of the maintenance personnel, reduces the cost of the data center, and improves the reliability of the cold air duct 4.

[0080] In some examples, as Figures 4 - 10 shown, the measurement probe 15 is fixed to the fourth end of the second rod 142. Wherein, the second rod 142 includes a third end and a fourth end, and the third end of the second rod 142 is rotatably connected to the second end of the first rod 141.

[0081] In some examples, the length A of the first rod 141 is greater than 40 cm and less than 50 cm.

[0082] In some examples, the length B of the second rod 412 is greater than 40 cm and less than 60 cm.

[0083] For the convenience of fixing the measurement probe mounting mechanism 14, in some examples, as Figure 9 and Figure 10As shown, the measurement probe mounting mechanism 14 further includes a base 143, and the base 143 is fixedly connected to the first end of the first rod 141. The base 143 is located in the maintenance space 101 and is fixedly connected to the partition 113. Among them, the setting of the base 143 facilitates the fixing of the measurement probe mounting mechanism 14 to the partition 113.

[0084] In some examples, such as Figure 9 and Figure 10 shown, the base 143 has a plurality of screw holes 1432. As Figure 7 shown, the measurement probe mounting mechanism 14 further includes a plurality of screws, and the plurality of screws respectively pass through the plurality of screw holes 1432 and are tightened on the partition 113.

[0085] In some examples, such as Figure 7 , Figure 9 and Figure 10 shown, the base 143 has a wire passing hole 1431, and the wire passing hole 1431 communicates with the through hole 1130. The measurement probe 15 has a connecting wire 151, and the connecting wire 151 passes through the wire passing hole 1431 and the through hole 1130.

[0086] The technical solution provided by the embodiments of the present disclosure facilitates the connecting wire 151 of the measurement probe 15 to pass through the base 143 and extend into the maintenance space 101 by providing the wire passing hole 1431 in the base 143.

[0087] In order to prevent the connecting wire 151 of the measurement probe 15 from swinging randomly in the air outlet space 102, in some examples, such as Figure 9 and Figure 10 shown, the connecting wire 151 is fixedly connected to the first rod 141 and the second rod 142 respectively. Moreover, since the connecting wire 151 is fixedly connected to both the first rod 141 and the second rod 142, the connecting wire 151 can also play a role in restricting the rotation of the first rod 141 and the second rod 142, so that the first rod 141 and the second rod 142 can be relatively stably maintained in the bent state.

[0088] The embodiments of the present disclosure do not limit the implementation manner of the fixing of the connecting wire 151 to the first rod 141 and the second rod 142. In some examples, such as Figure 9 and Figure 10 shown, the measurement probe mounting mechanism 14 further includes a cable tie 144, and the cable tie 144 tightens the connecting wire 151 and the first rod 141, and the connecting wire 151 and the second rod 142.

[0089] In some examples, in order to facilitate the positioning of the cable tie 144, such as Figure 9 and Figure 10 shown, both the first rod 141 and the second rod 142 have a cable tie fixing groove 140, and the cable tie 144 is located in the cable tie fixing groove 140.

[0090] In some examples, in order to enable the measurement probe mounting mechanism 14 to be stably in a bent state, as Figure 11 shown, the second end of the first rod 141 has a first limiting structure 1410, and the first limiting structure 1410 is located on the rotation path of the second rod 142. The first limiting structure 1410 is used to touch the second rod 142 so that the angle between the first rod 141 and the second rod 142 is not less than a target angle. Among them, in some examples, the target angle is 90°.

[0091] The technical solution provided by the embodiments of the present disclosure, as Figure 11 shown, after the first limiting structure 1410 touches the second rod 142, the second rod 142 cannot continue to rotate towards the first rod 141. Coupled with the fact that the connecting wires 151 of the measurement probe 15 are respectively fixed to the first rod 141 and the second rod 142, the second rod 142 cannot rotate away from the first rod 141 either. In this way, the measurement probe mounting mechanism 14 can be stably maintained in a bent state.

[0092] In other examples, as Figure 12 shown, the third end of the second rod 142 has a second limiting structure 1420. The second limiting structure 1420 is used to touch the first rod 141 so that the angle between the first rod 141 and the second rod 142 is not less than a target angle. Among them, the third end of the second rod 142 is the end of the second rod 142 close to the first rod 141.

[0093] In some examples, to reduce the possibility that the first rod 141 and the second rod 142 rotate randomly due to vibration or other reasons, as Figure 9 and Figure 10 shown, the measurement probe mounting mechanism 14 further includes a rotational damper 145, and the first rod 141 and the second rod 142 are rotatably connected through the rotational damper 145. Among them, the presence of the rotational damper 145 increases the force required to overcome the rotation of the first rod 141 and the second rod 142, so that the first rod 141 and the second rod 142 will not rotate randomly.

[0094] Next, with reference to Figure 13 , Figure 15 and Figure 16 , an exemplary description of the process of installing the measurement probe 15 in the maintenance space 101 will be given.

[0095] The first step, as Figure 13As shown from the first state to the second state of the temperature control unit 1, fix the connecting wire 151 of the measurement probe 15 to the second rod 142 so that the measurement probe 15 is fixed to the second rod 142. For example, use a cable tie 144 to fix the connecting wire 151 to the second rod 142. Then, keep the first rod 141 and the second rod 142 in the unfolded state, and insert the second rod 142 into the air outlet space 102 of the temperature control unit 1 through the through hole 1130 on the partition 113 until the second rod 142 is blocked by the blocking part 114 (as shown in the second state of Figure 13 ). Among them, in some examples, the blocking part 114 is the cylinder 111 of the housing 11.

[0096] The second step, as shown from the second state to the third state of the temperature control unit 1 in Figure 13 , pull the connecting wire 151 so that the second rod 142 rotates downward relative to the first rod 141. Among them, after the second step is completed, the state of the temperature control unit 1 is as shown in the third state of Figure 13 of the temperature control unit 1, and is also as shown in the temperature control unit 1 shown in Figure 15 .

[0097] The third step, as shown from the third state to the fourth state of the temperature control unit 1 in Figure 13 , fix the connecting wire 151 to the first rod 141. For example, use a cable tie 144 to fix the connecting wire 151 to the first rod 141.

[0098] The fourth step, as shown from the fourth state to the fifth state of the temperature control unit 1 in Figure 13 , insert the first rod 141 into the air outlet space 102 until the base 143 contacts the partition 113. Among them, after the fourth step is completed, the state of the temperature control unit 1 is as shown in the fifth state of Figure 13 of the temperature control unit 1, and is also as shown in the temperature control unit 1 shown in Figure 16 .

[0099] The fifth step, as shown from the fifth state to the sixth state of the temperature control unit 1 in Figure 13 , rotate the measurement probe mounting mechanism 14 as a whole so that the second rod 142 is located on the air outlet side of the heat exchanger 13. Then, fix the base 143 to the partition 113, and the installation of the measurement probe 15 is completed.

[0100] Next, in combination with Figures 14 - 16 , an exemplary description will be given of the process of disassembling the measurement probe 15 in the maintenance space 101.

[0101] The first step, as shown in Figure 14As shown by the first state to the second state of the temperature control unit 1, first, the fixed connection between the base 143 and the partition portion 113 is released. Then, the measurement probe mounting mechanism 14 is rotated integrally so that the second rod 142 is no longer on the air outlet side of the heat exchanger 13, but is in a state of rotating downward relative to the first rod 141. After the first step is completed, the state of the temperature control unit 1 is as Figure 14 shown by the second state of the temperature control unit 1 in Figure 16 and is also as shown by the temperature control unit 1 shown in

[0102] Second step, as shown by the second state to the third state of the temperature control unit 1 in Figure 14 operate the first rod 141 so that the first rod 141 gradually withdraws from the air outlet space 102 until the second rod 142 is blocked by the partition portion 113. After the second step is completed, the state of the temperature control unit 1 is as Figure 14 shown by the third state of the temperature control unit 1 in Figure 15 and is also as shown by the temperature control unit 1 shown in

[0103] Third step, as shown by the third state to the fourth state of the temperature control unit 1 in Figure 14 release the fixed connection between the connection line 151 and the first rod 141. For example, cut off the cable tie 144 wound around the first rod 141.

[0104] Fourth step, as shown by the fourth state to the fifth state of the temperature control unit 1 in Figure 14 operate (such as pushing) the connection line 151 so that the measurement probe mounting mechanism 14 is switched to the deployed state.

[0105] Fifth step, operate the measurement probe mounting mechanism 14 so that the measurement probe mounting mechanism 14 and the measurement probe 15 completely withdraw from the air outlet space 102. After that, detach the measurement probe 15 from the measurement probe mounting mechanism 14, and then the disassembly of the measurement probe 15 is completed.

[0106] It can be seen from the above process of disassembling and installing the measurement probe 15 that there may be a blocking portion 114 in the housing 11, and the blocking portion 114 hinders the disassembly and assembly of the measurement probe mounting mechanism 14, so that during the installation and disassembly of the measurement probe 15, the measurement probe mounting mechanism 14 needs to be in the Figure 15 and Figure 16 intermediate states shown.

[0107] As in Figure 15 and Figure 17As shown, it is assumed that the distance between the partition portion 113 and the blocking portion 114 is d1. Then, in order to enable the installation of the measurement probe mounting mechanism 14, the length A of the first rod 141 and the length B of the second rod 142 are both less than d1. In this way, it can be ensured that both the first rod 141 and the second rod 142 can extend into the air outlet space 102 without being blocked by the blocking portion 114.

[0108] In some examples, as Figure 15 and Figure 17 shown, since the second rod 142 is in a state of rotating downward relative to the first rod 141 during the disassembly and assembly process, the length B of the second rod 142 should be less than the distance H between the through hole 1130 and the bottom wall of the housing 11.

[0109] In some examples, as Figure 17 shown, the distance from the cable tie fixing groove 140 of the first rod 141 to the second end of the first rod 141 is C, and the length of the through hole 1130 is S. Then C is greater than S. Among them, if C is less than S, then as Figure 13 shown in the third state to the fourth state in, the maintenance personnel need to use a cable tie 144 to fix the connection line 151 to the first rod 141 in the through hole 1130, which is inconvenient or even impossible to operate.

[0110] The embodiments of the present disclosure do not limit the number of the measurement probe mounting mechanism 14 and the measurement probe 15 included in the temperature control unit 1. In some examples, as Figure 6 shown, the temperature control unit 1 includes one measurement probe mounting mechanism 14 and one measurement probe 15. In other examples, as Figure 18 shown, the temperature control unit 1 includes two measurement probe mounting mechanisms 14 and two measurement probes 15.

[0111] Exemplarily, as Figure 18 shown, the housing 11 includes two partition portions 113, and the two partition portions 113 are arranged on both sides of the heat exchanger 13. The two measurement probe mounting mechanisms 14 respectively pass through the two partition portions 113. In some examples, as Figure 18 shown, the temperature control unit 1 includes two fans 12, and the two measurement probes 15 are respectively opposite to the two fans 12.

[0112] In practical applications, the temperature control unit 1 has various specifications, and the sizes of the heat exchangers 13 in different specifications of the temperature control unit 1 may be different. For example, the thickness d2 of the heat exchangers 13 in different specifications of the temperature control unit 1 is different (as Figure 17As shown). In order to enable the measurement probe mounting mechanism 14 to be applied to temperature control units 1 of different specifications. In some examples, the embodiment of the present disclosure is configured such that the length of the first rod 141 can be adjusted. In this way, when the thickness d2 of the heat exchanger 13 is relatively large, the length of the first rod 141 is increased so that the length A of the first rod 141 is greater than the thickness d2 of the heat exchanger 13, ensuring that the second rod 142 can be located on the air outlet side of the heat exchanger 13.

[0113] The embodiment of the present disclosure does not limit the adjustment range of the length A of the first rod 141. In some examples, the adjustment range of the length A of the first rod 141 includes 40 cm - 50 cm.

[0114] The embodiment of the present disclosure does not limit the implementation manner of the adjustable length of the first rod 141. In some examples, as Figure 19 and Figure 20 shown, the first rod 141 includes a first inner rod 1411, a first outer rod 1412, a first elastic member 1413, and a first positioning member 1414. The side of the first inner rod 1411 has a first opening 14111. The first elastic member 1413 and the first positioning member 1414 are located in the first opening 14111, and a part of the first positioning member 1414 is driven by the first elastic member 1413 to extend out of the first opening 14111. The first outer rod 1412 has a plurality of first positioning holes 14121 arranged along the length direction. The first outer rod 1412 sleeves the first inner rod 1411, and the first positioning member 1414 extends into one of the first positioning holes 14121, thereby fixing the first inner rod 1411 and the first outer rod 1412. Moreover, by adjusting the first positioning hole 14121 into which the first positioning member 1414 extends, the length of the first rod 141 can be adjusted.

[0115] Among them, in some examples, as Figure 20 shown, the first positioning member 1414 has a groove, and the first elastic member 1413 extends into the groove of the first positioning member 1414. In some examples, the head of the first positioning member 1414 is spherical. The maximum outer diameter of the first positioning member 1414 is smaller than the inner diameter of the first positioning hole 14121 to prevent the first positioning member 1414 from disengaging from the first positioning hole 14121.

[0116] As Figure 20As shown, when the length of the first rod 141 needs to be adjusted, first, press the first positioning member 1414 so that the first positioning member 1414 disengages from the first positioning hole 14121. Then, move the first inner rod 1411 so that the first inner rod 1411 slides relative to the first outer rod 1412 until the first positioning member 1414 aligns with another first positioning hole 14121. Finally, under the action of the elastic force of the first elastic member 1413, the first positioning member 1414 extends into another first positioning hole 14121, and the length adjustment of the first rod 141 is completed.

[0117] In some other examples, the first rod 141 includes a first inner rod 1411 and a first outer rod 1412, and the first inner rod 1411 and the first outer rod 1412 are threadedly connected. Then, the length of the first rod 141 can be adjusted by rotating the first inner rod 1411 or the first outer rod 1412.

[0118] In some other examples, the first rod 141 includes a plurality of sub-rods, and the plurality of sub-rods are connected in sequence, such as by threaded connection. Then, by increasing or decreasing the number of sub-rods included in the first rod 141, the length of the first rod 141 can be adjusted.

[0119] In addition, the length L of the heat exchanger 13 in the temperature control unit 1 of different specifications may also be different (as Figure 18 shown). In order to enable the measurement probe mounting mechanism 14 to be applied to temperature control units 1 of different specifications, in some examples, the present disclosure embodiment sets the length of the second rod 142 to be adjustable. In this way, when the length L of the heat exchanger 13 is relatively long, the length B of the second rod 142 is adjusted to be relatively long so that the end of the second rod 142 (i.e., the measurement probe 15) is close to the central position of the heat exchanger 13 to ensure the measurement effect of the measurement probe 15.

[0120] The present disclosure embodiment does not limit the adjustment range of the length of the second rod 142. In some examples, the adjustment range of the length B of the second rod 142 includes 40 cm - 60 cm.

[0121] The present disclosure embodiment does not limit the implementation manner in which the length of the second rod 142 can be adjusted. In some examples, such as Figure 21 and Figure 22As shown, the second rod 142 includes a second inner rod 1421, a second outer rod 1422, a second elastic member 1423, and a second positioning member 1424. A second opening 14211 is provided on the side of the second inner rod 1421. The second elastic member 1423 and the second positioning member 1424 are located in the second opening 14211, and a part of the second positioning member 1424 is driven by the second elastic member 1423 to protrude from the second opening 14211. The second outer rod 1422 has a plurality of second positioning holes 14221 arranged along the length direction. The second outer rod 1422 sleevingly surrounds the second inner rod 1421. The second positioning member 1424 extends into one of the second positioning holes 14221, and by adjusting the second positioning hole 14221 into which the second positioning member 1424 extends, the length of the second rod 142 can be adjusted.

[0122] Among them, in some examples, as Figure 22 shown, the second positioning member 1424 has a groove, and the second elastic member 1423 extends into the groove of the second positioning member 1424. In some examples, the head of the second positioning member 1424 is spherical. The maximum outer diameter of the second positioning member 1424 is smaller than the inner diameter of the second positioning hole 14221 to prevent the second positioning member 1424 from disengaging from the second positioning hole 14221.

[0123] As Figure 22 shown, when the length of the second rod 142 needs to be adjusted, first, press the second positioning member 1424 so that the second positioning member 1424 disengages from the second positioning hole 14221. Then, operate the second inner rod 1421 so that the second inner rod 1421 slides relative to the second outer rod 1422 until the second positioning member 1424 aligns with another second positioning hole 14221. Finally, under the action of the elastic force of the second elastic member 1423, the second positioning member 1424 extends into another second positioning hole 14221, and the length adjustment of the second rod 142 is completed.

[0124] In other examples, the second rod 142 includes a second inner rod 1421 and a second outer rod 1422, and the second inner rod 1421 and the second outer rod 1422 are threadedly connected. Then, by rotating the second inner rod 1421 or the second outer rod 1422, the length of the second rod 142 can be adjusted.

[0125] In other examples, the second rod 142 includes a plurality of sub-rods, and the plurality of sub-rods are connected in sequence, such as by threaded connection. Then, by increasing or decreasing the number of sub-rods included in the second rod 142, the length of the second rod 142 can be adjusted.

[0126] It should be noted that, in some examples, as Figure 19 shown, the length of the first rod 141 can be adjusted, and the length of the second rod 142 is fixed. In other examples, as Figure 21As shown, the length of the first rod 141 is fixed, and the length of the second rod 142 can be adjusted. In some other examples, such as Figure 23 shown, the lengths of both the first rod 141 and the second rod 142 can be adjusted.

[0127] In some examples, such as Figure 19 and Figure 23 shown, the first outer rod 1412 is fixedly connected to the base 143, and the first inner rod 1411 is rotatably connected to the second rod 142.

[0128] In some examples, such as Figure 21 and Figure 23 shown, the second outer rod 1422 is rotatably connected to the first rod 141, and the measuring probe 15 is disposed on the second inner rod 1421.

[0129] The embodiments of the present disclosure further provide a measuring probe mounting mechanism 14. As Figure 9 and Figure 10 shown, the measuring probe mounting mechanism 14 includes a first rod 141 and a second rod 142. The first end of the first rod 141 is used to pass through the through hole 1130 of the partition portion 113 of the temperature control unit 1. The second end of the first rod 141 is located in the air outlet space 102 of the temperature control unit 1 and is rotatably connected to the second rod 142. Among them, the partition portion 113 is adjacent to the heat exchanger 13 of the temperature control unit 1 and separates the maintenance space 101 and the air outlet space 102 of the temperature control unit 1. The second rod 142 is used to fix the measuring probe 15.
