Description

Technical Field

[0001] This utility model relates to the field of battery capacity testing cabinet technology, specifically a temperature control device for a battery capacity testing cabinet. Background Technology

[0002] Battery capacity grading is accomplished through a capacity grading cabinet. The capacity grading cabinet functions similarly to a charger, except that it can charge and discharge a large number of batteries simultaneously. During battery capacity grading, data from each detection point is obtained through computer management, thereby analyzing data such as the capacity and internal resistance of these batteries to determine their quality level. This process is called capacity grading. The internal temperature of the battery capacity grading cabinet continuously rises during operation, and a temperature control device for the battery capacity grading cabinet is needed.

[0003] Existing temperature control devices cannot rapidly reduce the local temperature inside the battery grading cabinet to a suitable range within a short time. Their dustproof performance is also inadequate, allowing dust from the outside air to easily enter the cabinet, thus reducing its dustproof effectiveness. Furthermore, their temperature control is not precise enough, further reducing its effectiveness in controlling the internal temperature of the cabinet. In addition, existing temperature control devices are inconvenient to maintain, making it difficult for users to inspect or replace the rotating motor and cooling fan, thus hindering operation.

[0008] Preferably, a solenoid valve is fitted onto the surface of the water inlet pipe, and the input end of the solenoid valve is electrically connected to the output end of the controller. A water-cooling plate is installed on the surface of the top position of the plate body by screws. The water-cooling plate is fixed to the surface of the bottom position of the battery clamp.

[0009] Preferably, the convenient maintenance mechanism consists of a guide block, a guide groove, a mounting slot, a mounting block, and a support plate.

[0014] 1. By incorporating a dustproof and ash-blocking mechanism, the user places the dustproof covers on the surface of the device frame plate and then tightens the mounting studs on the mounting block surface. Under the action of the mounting studs, the dustproof covers are installed on the surface of the device frame plate. Subsequently, the user places the dust-blocking net on the surface of the dustproof covers and tightens the fastening bolts on the block surface. The dust-blocking net can block dust and other impurities in the outside air. If the user needs to clean the surface of the dust-blocking net, the user loosens the fastening bolts on the block surface and then pulls the dust-blocking net upward to remove it from the surface of the dustproof cover for cleaning. This achieves the dustproof and ash-blocking function of the temperature control device, thereby reducing the amount of dust in the outside air entering the battery capacity cabinet body during the use of the temperature control device, resulting in better dustproof performance during the use of the temperature control device.

[0015] 2. Equipped with a precise temperature control mechanism, the water pump inside the chamber operates, drawing out the coolant from the chiller unit and guiding it into the outlet pipe. The coolant then flows through the pipes and tubes on the surface of the outlet pipe into the interior of the water-cooled plate. The coolant circulates within the water-cooled plate, absorbing the heat generated by the battery body during operation. The controller opens the solenoid valve on the inlet pipe, allowing the coolant inside the water-cooled plate to flow back to the chiller unit through the fixed pipes and tubes. This achieves precise temperature control, significantly improving the accuracy of temperature control within the battery capacity cabinet and resulting in better temperature control performance.

[0016] 3. By incorporating a convenient maintenance mechanism, pulling the orifice plate upwards causes the rotating motor, motor cover, cooling fan, and fan cover to move upwards. The orifice plate then drives the guide block to slide inside the guide groove. Under the combined action of the guide block and the guide groove, the orifice plate is guided. At this point, the orifice plate moves the mounting block away from the inside of the mounting groove, thereby removing the rotating motor, motor cover, orifice plate, cooling fan, and fan cover from inside the device frame. This allows for the inspection and replacement of the rotating motor and cooling fan, thus enabling convenient maintenance of the temperature control device. This makes it easier for users to inspect and replace the rotating motor and cooling fan during use, making the temperature control device more convenient to operate. Attached Figure Description

The interior of each mounting plate 1 has a perforated plate 114. A fan shroud 116 is mounted on the bottom surface of the perforated plate 114. A cooling fan 115 is installed inside the fan shroud 116. The cooling fan 115 and the inner wall of the fan shroud 116 rotate in relation to each other. The perforated plate 114 and... The inner wall of the fan cover 116 is provided with through holes. The surface of the top center position of the perforated plate 114 is fitted with a motor cover 113 by screws. The motor cover 113 is fitted with a rotating motor 112. The rotating motor 112 can be a JO series model. The input end of the rotating motor 112 is electrically connected to the output end of the controller 101. The output end of the rotating motor 112 is fitted with a rotating shaft through a coupling. One end of the rotating shaft passes through the perforated plate 114 and the fan cover 116 in sequence and is fixed to the surface of the center position of the cooling fan 115.

[0025] Furthermore, such as Figure 2As shown, a precision temperature control mechanism 2 is installed on one side of the device frame 1 and inside the cavity 103. The precision temperature control mechanism 2 consists of a fixed pipe 21, a water-cooled plate 22, an inlet pipe 23, an outlet pipe 24, a solenoid valve 25, a water pump 26, and a pipe body 27. The water pump 26 is installed inside the cavity 103. The model of the water pump 26 can be SLG series. The input end of the water pump 26 is electrically connected to the output end of the controller 101. The input end of the water pump 26 passes through the chiller unit 107 and extends into the interior of the chiller unit 107. The output end of the water pump 26 extends into the interior of the battery capacity distribution cabinet body 102. The outlet pipe 24 is installed inside the battery capacity distribution cabinet body 102. The outlet pipe 24 is connected to the output end of the water pump 26. Connected to the battery capacity cabinet body 102, an inlet pipe 23 is installed inside. The bottom end of the inlet pipe 23 extends into the interior of the chiller unit 107. A solenoid valve 25 is fitted on the surface of the inlet pipe 23. The solenoid valve 25 can be of the TM series. The input end of the solenoid valve 25 is electrically connected to the output end of the controller 101. A water-cooled plate 22 is installed on the surface of the top position of the plate 106 by screws. The water-cooled plate 22 is fixed to the surface of the bottom position of the battery clamp 111.

A pipe body 27 is installed on one side of the surface of the water-cooled plate 22. The pipe body 27 is connected to the outlet pipe 24 through a pipe.

[0026] During implementation, the water pump 26 inside the control cavity 103 operates, drawing out the coolant from the chiller unit 107 and guiding it into the outlet pipe 24. The coolant then enters the water-cooled plate 22 through the pipe and pipe body 27 on the surface of the outlet pipe 24. The coolant circulates within the water-cooled plate 22, absorbing the heat generated by the battery body 110 on the surface of the battery clamp 111 during operation. Subsequently, the controller 101 controls the solenoid valve 25 on the surface of the inlet pipe 23 to open, allowing the coolant inside the water-cooled plate 22 to flow back to the chiller unit 107 through the fixed pipe 21 and pipe. The coolant is then cooled within the chiller unit 107. The cooled liquid is then recirculated by the water pump 26, continuously dissipating heat from the surface of the battery body 110, significantly improving the heat dissipation efficiency for the surface of the battery body 110 and the inside of the battery capacity cabinet 102, thus achieving precise temperature control by the temperature control device.

[0027] Furthermore, such as Figure 3 and Figure 4As shown, the inner wall of the device frame plate 1 and the surface of the perforated plate 114 are provided with a convenient maintenance mechanism 3. The convenient maintenance mechanism 3 consists of a guide block 31, a guide groove 32, a mounting slot 33, a mounting block 34, and a support plate 35. Guide blocks 31 are installed on both sides of the perforated plate 114. Guide grooves 32 are opened on the inner wall of the device frame plate 1. The surfaces of the guide grooves 32 and the guide blocks 31 slide against each other. Support plates 35 are installed on the inner wall of the device frame plate 1. The support plates 35 are located below the perforated plate 114. Mounting blocks 34 are installed on the surface at the bottom of the perforated plate 114. Mounting slots 33 are opened on the surface of the support plate 35. The surfaces of the mounting slots 33 and the mounting blocks 34 engage with each other.

[0028] During implementation, the perforated plate 114 is pulled upwards, causing the perforated plate 114 to drive the rotating motor 112, motor cover 113, cooling fan 115, and fan cover 116 to move upwards. The perforated plate 114 drives the guide block 31 to slide inside the guide groove 32. Under the combined action of the guide block 31 and the guide groove 32, the perforated plate 114 is guided. At this time, the perforated plate 114 drives the mounting clip 34 away from the inside of the mounting clip 33, thereby removing the rotating motor 112, motor cover 113, perforated plate 114, cooling fan 115, and fan cover 116 from the inside of the device frame plate 1. The rotating motor 112 and cooling fan 115 are then inspected and replaced to facilitate the maintenance of the temperature control device.

[0029] Furthermore, such as Figure 3 and Figure 5 As shown, a dustproof and dust-blocking mechanism 4 is provided on the surface of the top position of the device frame plate 1. The dustproof and dust-blocking mechanism 4 is composed of a mounting block 41, a mounting stud 42, a dustproof cover 43, a dustproof net 44, a fastening bolt 45, and a block 46. A dustproof cover 43 is provided on the top of the device frame plate 1. A dustproof net 44 is provided on the surface of the dustproof cover 43. A block 46 is installed on the surface of the top position of the dustproof net 44. A fastening bolt 45 is threadedly connected to the surface of the block 46. One end of the fastening bolt 45 passes through the block 46 and is threadedly fastened to the surface of the dustproof cover 43. Mounting blocks 41 are installed on both sides of the dustproof cover 43. A mounting stud 42 is threadedly connected to the surface of the mounting block 41. One end of the mounting stud 42 passes through the mounting block 41 and is threadedly fastened to the surface of the device frame plate 1.

[0030] In practice, the user places the dust cover 43 on the surface of the device frame plate 1, and then tightens the mounting studs 42 on the surface of the mounting block 41. Under the action of the mounting studs 42, the dust cover 43 is installed on the surface of the device frame plate 1. Then, the user places the dust net 44 on the surface of the dust cover 43, so that the dust net 44 moves the block 46 to contact the surface of the dust cover 43. The user tightens the fastening bolts 45 on the surface of the block 46. Under the action of the fastening bolts 45, the dust net 44 is installed on the surface of the dust cover 43. Under the action of the fastening bolts 45, the dust net 44 can block dust and other impurities in the outside air. If the user needs to clean the surface of the dust net 44, the user loosens the fastening bolts 45 on the surface of the block 46 and then pulls the dust net 44 upward to remove the dust net 44 from the surface of the dust cover 43 and clean the surface of the dust net 44 to realize the dust prevention and dust blocking function of the temperature control device.

[0031] Working principle: In use, first place the device frame 1 in the designated position. The user places the dust cover 43 on the surface of the device frame 1, and then tightens the mounting studs 42 on the surface of the mounting block 41. Under the action of the mounting studs 42, the dust cover 43 is installed on the surface of the device frame 1. Then, the user places the dust net 44 on the surface of the dust cover 43, causing the dust net 44 to move the block 46 until it contacts the surface of the dust cover 43. The user then tightens the fastening bolts 45 on the surface of the block 46, and under the action of the fastening bolts 45, the dust net 44 is installed on the dust cover 43. The surface of the cover 3, under the action of the dustproof net 44, can block dust and other impurities in the outside air. If the user needs to clean the surface of the dustproof net 44, the user can loosen the fastening bolt 45 on the surface of the block 46 and then pull the dustproof net 44 upward to remove the dustproof net 44 from the surface of the dustproof cover 43 and clean the surface of the dustproof net 44 to realize the dustproof function of the temperature control device. This reduces the amount of dust in the outside air entering the interior of the battery capacity cabinet body 102 when the temperature control device is in use, making the dustproof effect of the temperature control device better when in use.

[0032] Subsequently, the user places the device holder 1 on the surface of the battery capacity grading cabinet body 102, and then tightens the screws on the surface of the assembly block 104 to install the device holder 1 on the surface of the battery capacity grading cabinet body 102. When the battery capacity grading cabinet body 102 is started, the controller 101 controls the rotating motor 112 inside the motor cover 113 to work. Under the action of the rotating motor 112, the rotating shaft is driven to rotate on the inner wall of the perforated plate 114. When the rotating shaft rotates, the rotating shaft drives the cooling fan 115 to rotate inside the fan cover 116, so that the outside air can enter the interior of the battery capacity grading cabinet body 102 through the through hole. Under the action of the temperature sensor 105, the temperature inside the battery capacity grading cabinet body 102 is monitored in real time.

[0033] Subsequently, when the temperature sensor 105 detects that the temperature inside the battery capacity grading cabinet 102 is too high, the temperature sensor 105 sends a signal to the controller 101. After receiving the signal from the temperature sensor 105, the controller 101 automatically controls the water pump 26 inside the cavity 103 to work. Under the action of the water pump 26, the coolant inside the chiller unit 107 is drawn out and then introduced into the interior of the outlet pipe 24. Through the pipe and pipe body 27 on the surface of the outlet pipe 24, it enters the interior of the water-cooled plate 22. The coolant circulates inside the water-cooled plate 22, absorbing the heat generated by the battery body 110 on the surface of the battery clamp 111 during operation. Subsequently, the controller 101 controls the water inlet pipe 2... The solenoid valve 25 on surface 3 opens, allowing the coolant inside the water-cooled plate 22 to flow back to the chiller unit 107 through the fixed pipe 21 and the pipeline. Inside the chiller unit 107, the coolant is cooled. The cooled liquid is then recirculated by the water pump 26, continuously dissipating heat from the surface of the battery body 110. This significantly improves the heat dissipation efficiency of the battery body 110 surface and the inside of the battery capacity cabinet 102, enabling precise temperature control by the temperature control device. This greatly improves the temperature control accuracy of the battery capacity cabinet 102, resulting in better temperature control performance. Subsequently, the user operates the controller 101, which activates the valve 108 on the surface of the drain pipe 109, allowing the coolant inside the chiller unit 107 to be discharged through the drain pipe 109 for replacement.

[0034] Subsequently, when the rotating motor 112 and cooling fan 115 malfunction or break down after prolonged use, the user removes the dustproof and dust-blocking mechanism 4 from the surface of the device frame plate 1, and then pulls the perforated plate 114 upwards. This causes the perforated plate 114 to move the rotating motor 112, motor cover 113, cooling fan 115, and fan cover 116 upwards. The perforated plate 114 then drives the guide block 31 to slide inside the guide groove 32. Under the combined action of the guide block 31 and the guide groove 32, the perforated plate 114 is guided. At this time, the perforated plate 114 moves the mounting clip 34 away from the inside of the mounting clip 33, thereby removing the rotating motor 112, motor cover 113, and fan cover 116. Plate 114, cooling fan 115, and fan cover 116 are removed from the inside of the device frame plate 1. The rotating motor 112 and cooling fan 115 are inspected and replaced to facilitate the maintenance of the temperature control device. This makes it easier for users to inspect and replace the rotating motor 112 and cooling fan 115 during use, making the temperature control device more convenient to operate. The controller 101 controls the temperature sensor 105, rotating motor 112, solenoid valve 25, and water pump 26. The specific connection and control methods are existing technologies and will not be described in detail here. Finally, the use of the temperature control device is completed.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
