[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of the infrared transmitting tube, the infrared transmitting tube can emit an infrared light signal to the front. When the infrared light passes through the liquid cooling medium, it will be attenuated due to the impurities in the liquid cooling medium. The infrared light signal is received by the infrared receiving tube after passing through the detection channel. Then the data acquisition module collects the attenuation degree of the infrared light signal received by the infrared receiving tube, and transmits it to the processing module in the form of an electrical signal. Through the setting of the conductivity sensor, when the liquid cooling medium contains impurities, the conductivity of the liquid cooling medium detected by the conductivity sensor will change. The impurity concentration in the liquid cooling medium can be detected by the change in conductivity. The conductivity change detected by the conductivity sensor is collected through the data acquisition module, and then transmitted to the processing module in the form of an electrical signal. The processing module processes and judges the attenuation degree of the infrared light signal and the conductivity change. When it exceeds the preset threshold, the remote module sends a text message reminder to the user, and controls the normal indicator light to jump to the abnormal indicator light, which solves the problem that traditional liquid cooling cabinets often cannot remind users to replace the internal liquid cooling medium.

[0015] 2. The user can pull out the sealing plug at the top of the liquid inlet pipe, and inject the external cooling medium into the circular liquid distributor through the liquid inlet pipe. The external cooling medium enters into the multiple cooling tanks through the circular liquid distributor. After the injection is completed, the sealing plug can be reinserted into the liquid inlet pipe. Through the setting of the first water pump, the liquid cooling medium can be drawn out from the cabinet body. The liquid cooling medium enters into the multiple liquid outlet pipes through the multiple solenoid valves, enters into the multiple first connecting pipes through the multiple first water pumps, and then enters into the multiple cooling pipes. Through the external cooling medium in the multiple cooling tanks, the liquid cooling medium enters into the multiple first connecting pipes through the multiple first water pumps. The medium can perform heat exchange with the liquid-cooling medium in multiple groups of cooling tubes, thereby cooling the liquid-cooling medium. Through the cooperation of multiple groups of heat dissipation fins and multiple groups of heat dissipation copper plates, the external cooling medium in multiple groups of cooling tanks can be cooled. Then the cooled liquid-cooling medium enters the circular liquid collector, and the cooled liquid-cooling medium is pumped into the return pipe through the second water pump, and then flows back to the cabinet body through the one-way valve, so as to continuously circulate, thereby cooling the liquid-cooling medium in the cabinet body. Compared with the single-tube cooling of the traditional liquid-cooled cabinet, the cooling efficiency is improved.

[0016] 3. The user can place the external server into the storage frame, and place the storage frame into the placement rack by pulling the handle. When the storage frame is placed into the placement rack, the rolling wheel at one end of the storage frame presses down the limit card, and then the rolling wheel continues to slide down along the rolling groove. The limit card is reset by the reset spring, and the rolling wheel is limited. This can prevent the user from pulling out the storage frame when the external server connection cable is not removed, causing damage to the external server, thereby improving safety.

The cooling assembly also includes multiple groups of cooling pipes 153, one end of each of the multiple groups of cooling pipes 153 is penetrated in the cooling tank 149, and one end of each of the multiple groups of cooling pipes 153 passes through the cooling base 148, a circular liquid collector 158 is provided at the bottom of the cooling base 148, the top of the circular liquid collector 158 is connected to the bottom of the cooling base 148, one end of multiple groups of cooling pipes 153 are connected to the top of the circular liquid collector 158, one end of multiple groups of solenoid valves 144 are connected to the liquid outlet pipe 145, one end of multiple groups of liquid outlet pipes 145 are connected to the first water pump 146, one end of multiple groups of first water pumps 146 are connected to the cooling pipe 153 through the first connecting pipe 147, one end of the circular liquid collector 158 is connected to the second connecting pipe 159, one end of the second connecting pipe 159 is connected to the second water pump 160, a one-way valve 162 is clamped on the side of the cabinet body 100 close to the second water pump 160, and one end of the second water pump 160 is connected to the one-way valve 162 through the reflux pipe 161.

[0026] By setting the first water pump 146, the liquid cooling medium can be pumped out from the cabinet body 100, and the liquid cooling medium enters the multiple groups of liquid outlet pipes 145 through the multiple groups of solenoid valves 144, enters the multiple groups of first connecting pipes 147 through the multiple groups of first water pumps 146, and then enters the multiple groups of cooling pipes 153. The external cooling medium in the multiple groups of cooling tanks 149 can perform heat exchange with the liquid cooling medium in the multiple groups of cooling pipes 153, thereby cooling the liquid cooling medium. The hot copper plate 150 is used to cool the external cooling medium in multiple groups of cooling tanks 149. The cooled liquid cooling medium then enters the circular liquid collector 158, and is pumped into the return pipe 161 by the second water pump 160. It then flows back to the cabinet body 100 through the one-way valve 162, and circulates continuously to cool the liquid cooling medium in the cabinet body 100. Compared with the single-tube cooling of traditional liquid-cooled cabinets, this device uses multi-tube cooling to improve the cooling efficiency.

Multiple groups of rolling grooves 117 are opened on the inner side surfaces at both ends of the placement rack 101, and the multiple groups of rolling wheels 107 are clamped in the rolling grooves 117. When the user puts the storage frame 105 into the placement rack 101, the multiple groups of rolling wheels 107 can roll in the rolling grooves 117. A limited position component is arranged in the placement rack 101 , a plurality of rotating shafts 108 are provided on the inner side of one end of the storage frame 105, and the limiting components include a plurality of limiting card plates 110 and a plurality of reset springs 109. Both ends of the plurality of rotating shafts 108 are sleeved with limiting card plates 110, and the limiting card plates 110 can limit the rolling wheels 107, and the plurality of limiting card plates 110 are corresponding to the plurality of rolling wheels 107 of the plurality of storage frames 105 close to the pulling members 113, and reset springs 109 are provided between the plurality of limiting card plates 110 and the plurality of rotating shafts 108, through the reset springs The spring 109 can reset the limit card plate 110. The limit assembly also includes a linkage plate 112 and multiple linkage parts 111. The multiple linkage parts 111 are all arranged in the placement rack 101. One end of the multiple linkage parts 111 is connected to the limit card plate 110. The other end of the multiple linkage parts 111 is provided with the same linkage plate 112. When the linkage plate 112 moves upward, it will drive the linkage parts 111 to move upward together. The linkage parts 111 drive the limit card plate 110 to rotate downward, thereby canceling the limit of the rolling wheel 107. Two groups of pulling pieces 113 are arranged on the top of the movable plate 112. The user can put his fingers into the pulling pieces 113 and pull the linkage plate 112 through the pulling pieces 113.

[0028] The user can place the external server into the storage frame 105, and place the storage frame 105 into the placement rack 101 by pulling the handle 118. When the storage frame 105 is placed into the placement rack 101, the rolling wheel 107 at one end of the storage frame 105 presses down the limiting card plate 110, and then the rolling wheel 107 continues to slide downward along the rolling groove 117. The limiting card plate 110 is reset under the drive of the reset spring 109, and the rolling wheel 107 is limited. This can prevent the user from pulling out the storage frame 105 when the external server connection line is not removed, causing damage to the external server, thereby improving safety.

The pulling member 113 drives the linkage plate 112 to move upwards, and the linkage plate 112 simultaneously drives the linkage member 111 to move upwards. The limiting card plate 110 rotates under the drive of the linkage member 111 to cancel the limit on the scroll wheel 107. When the fixing hole 116 is aligned with the hole on the fixing seat 114, the fixing pin 115 can be inserted into the fixing hole 116 and the fixing seat 114. At this time, the limiting card plate 110 is locked and will not be reset due to the reset spring 109. The user can remove the connection line of the external server and pull the storage frame 105 upwards by pulling the handle 118. When the fixing pin 115 is pulled out again, the linkage plate 112 resets downward, and the limiting card plate 110 also resets accordingly.

Through the arrangement of the cooling baffles 202, the space inside the cooling box 201 can be divided into a plurality of cooling chambers. A plurality of flow holes 203 are provided through one side of the plurality of cooling baffles 202. A detachable cooling cover 206 is arranged at one end of the cooling box 201, and a reflux collector 207 is arranged at one end of the cooling cover 206. The cooling component also includes a plurality of cooling fans 204 and a plurality of semiconductor cooling sheets 205. The semiconductor cooling sheets 205 can be used for cooling. The plurality of cooling fans 204 are arranged on one side of the cooling box 201. Through the arrangement of the cooling fans 204 and the semiconductor cooling sheets 205, the liquid flowing in the plurality of first connecting pipes 147 can be cooled. The medium is cooled, a dustproof net 209 is provided on the other side of the cooling box 201, multiple groups of semiconductor refrigeration plates 205 are arranged on the inner side of the cooling box 201, one end of multiple groups of solenoid valves 144 corresponds to the liquid outlet channel 103, one end of multiple groups of solenoid valves 144 is connected to the liquid outlet pipe 145, one end of multiple groups of liquid outlet pipes 145 is connected to the first water pump 146, one end of multiple groups of first water pumps 146 is connected to the first connecting pipe 147, one end of multiple groups of first connecting pipes 147 passes through the cooling box 201 and the cooling cover plate 206, and is connected to the reflux collector 207, one end of the reflux collector 207 is connected to the connecting pipe 208, one end of the connecting pipe 208 is connected to the second water pump 160, a one-way valve 162 is provided on one side of the cabinet body 100, and one end of the second water pump 160 is connected to the one-way valve 162 through the reflux pipe 161.

[0034] Compared with the method of cooling the liquid cooling medium by using the cooling tank 149 and the cooling pipe 153 in the first embodiment, the second embodiment cools the cooling chamber divided by the cooling partition 202 in the cooling box 201 by the semiconductor cooling sheet 205, and blows air into the cooling box 201 by the cooling fan 204, so as to take away the air after the heat exchange. The main difference is that when the liquid cooling medium flows into the first connecting pipe 147, the cooling fan 204 cools the liquid cooling medium in the first connecting pipe 147 by the semiconductor cooling sheet 205. After cooling, the cooled liquid cooling medium enters the reflux collector 207, and then the second water pump 160 draws the liquid cooling medium into the reflux pipe 161 through the connecting pipe 208, and returns to the cabinet body 100 through the one-way valve 162, so as to circulate. Therefore, compared with the method of cooling the liquid cooling medium by the cooling tank and the cooling pipe 153, the cooling fan 204 and the semiconductor refrigeration sheet 205 can better dissipate the heat of the liquid cooling medium, and occupy less space. The other conditions are consistent with the embodiment 1, so this embodiment will not be repeated.
