DETAILED DESCRIPTION

[0032] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0033] Referring to Figure 1 and Figure 2 , the constant temperature cooling device for culture medium disclosed in the embodiments of the present application comprises a cabinet body 1, a cooling assembly 2 and a rotating assembly 3. The cabinet body 1 is a hollow square body. A door panel 11 is hingedly connected to one side of the cabinet body 1. A transparent observation window 12 is installed on the door panel 11, so that the experimenters can see the situation inside the cabinet body 1 at any time. A control panel 13 is also installed on the outer side wall of the cabinet body 1 close to the door panel 11. The control panel 13 is located above the door panel 11. The experimenters can adjust the target cooling temperature of the culture medium by operating the control panel 13. The cooling assembly 2 and the rotating assembly 3 are both arranged on the cabinet body 1.

[0034] Referring to Figure 2 and Figure 3 , the cooling assembly 2 comprises an air cooling component 21 and a water cooling component 22. The air cooling component 21 comprises a first cooling fan 211 and a second cooling fan 212. The first cooling fan 211 and the second cooling fan 212 are installed on the opposite side walls of the cabinet body 1 by bolts. The air directions of the two cooling fans are opposite, which can accelerate the air flow and timely discharge the heat emitted by the culture medium into the cabinet body 1.

[0035] The water cooling part 22 comprises a liquid storage cylinder 221, a water pump 222 and a cooling liquid pipe 223. The liquid storage cylinder 221 is a hollow square body, and the inner wall of the liquid storage cylinder 221 stores cooling liquid. The liquid storage cylinder 221 is fixedly installed on the outer side wall of the cabinet body 1 away from the door panel 11 by means of bolts. The water pump 222 is also fixedly installed on the outer side wall of the cabinet body 1 away from the door panel 11 by means of bolts. The water inlet of the water pump 222 is in communication with the liquid storage cylinder 221, and the water outlet is in communication with the cooling liquid pipe 223. The end of the cooling liquid pipe 223 away from the water pump 222 is in communication with the liquid storage cylinder 221. The cooling liquid pipe 223 comprises a first heat dissipation part 2231 and a second heat dissipation part 2232. The first heat dissipation part 2231 is fixedly installed on the inner top wall of the cabinet body 1 in a serpentine shape. The second heat dissipation part 2232 is fixedly installed on the inner bottom wall of the cabinet body 1 in a serpentine shape. The first heat dissipation part 2231 and the second heat dissipation part 2232 can increase the contact area of the cooling liquid pipe 223 and the hot air in the cabinet body 1, and can absorb as much heat as possible in the cabinet body 1.

[0036] With reference to Figure 3 It should be noted that the cabinet body 1 further comprises a heat dissipation plate 4 fixedly installed on the outer side wall of the cabinet body 1 away from the door panel 11. The cooling liquid pipe 223 penetrates the heat dissipation plate 4. After the cooling liquid absorbs the heat in the cabinet body 1, the cooling liquid can transfer the heat to the heat dissipation plate 4 when passing through the heat dissipation plate 4. The heat dissipation plate 4 further transfers the heat to the surrounding environment, thereby improving the cooling efficiency of the water cooling part 22.

[0037] With reference to Figure 2 and Figure 4 The rotating assembly 3 comprises a driving part 31 and a plurality of racks 32. The driving part 31 comprises a motor 311, a rotating plate 312 and a plurality of support rods 313. The motor 311 is fixedly installed on the side wall of the cabinet body 1 away from the door panel 11 by means of bolts. The output shaft of the motor 311 penetrates the side wall of the cabinet body 1 and is fixedly connected with the rotating plate 312. The rotating plate 312 is a circular plate and is rotatably connected in the cabinet body 1. The support rods 313 are cylindrical bodies. The plurality of support rods 313 are welded to the side wall of the rotating plate 312 away from the motor 311 in a circumferential direction along the axis of the rotating plate 312. The axes of the support rods 313 are parallel to the axis of the rotating plate 312. The plurality of support rods 313 correspond to the plurality of racks 32 one by one. The racks 32 are rotatably connected to the support rods 313 at the top. A plurality of ventilation openings are formed in the side wall of the racks 32, so that the heat of the culture medium can be quickly dissipated into the cabinet body 1.

[0038] When the culture medium is cooled, the motor 311 is started. The output shaft of the motor 311 drives the rotating plate 312 and the support rods 313 to rotate. The racks 32 rotate with the support rods 313, so that the culture medium can change position, thereby avoiding too slow or too fast cooling speed.

[0039] With reference to Figure 4The bottom wall of the placing frame 32 is slidably connected with a bearing plate 5, and the top of the bearing plate 5 is integrally formed with a limiting plate 51 away from the rotating plate 312. When the experimenter places the culture medium, the bearing plate 5 is pulled towards the door plate 11, the culture medium is placed on the bearing plate 5, and then the bearing plate 5 is pushed back, which is convenient for the experimenter to operate.

[0040] In addition, the temperature sensor 6 is fixedly installed on each bearing plate 5, the control panel 13 is electrically connected with the plurality of temperature sensors 6 through the controller, and the plurality of temperature sensors 6 are electrically connected with the first cooling fan 211 and the second cooling fan 212 through the controller.

[0041] Therefore, the experimenter can set the target cooling temperature of the culture medium through the control panel 13, the temperature sensor 6 can detect the temperature of the culture medium in real time, when the temperature sensor 6 detects that the temperature of the culture medium is too high, the controller increases the output power of the first cooling fan 211 and the second cooling fan 212 to accelerate the air circulation, so that the heat emitted by the culture medium in the cabinet 1 is blown out of the cabinet 1 faster, thereby accelerating the cooling speed of the culture medium; when the temperature sensor 6 detects that the temperature of the culture medium is close to the target cooling temperature, the controller reduces the output power of the first cooling fan 211 and the second cooling fan 212 to reduce energy consumption.

[0042] The implementation principle of the medium constant-temperature cooling device is as follows: after the culture medium is sterilized at high temperature, the experimenter opens the door plate 11, pulls the bearing plate 5 towards the door plate 11, places the culture medium on the bearing plate 5, pushes the bearing plate 5 back, closes the door plate 11, and sets the target cooling temperature of the culture medium through the control panel 13. Then the first cooling fan 211, the second cooling fan 212, the water pump 222 and the motor 311 are started at the same time, the first cooling fan 211 and the second cooling fan 212 blow the hot air in the cabinet 1 out, realize the circulation replacement of the external gas and the gas in the cabinet 1, and take away the heat in the cabinet 1. At the same time, the water pump 222 pumps the cooling liquid into the cooling liquid pipe 223, absorbs the heat in the cabinet 1, and then transmits the heat to the heat dissipation plate 4 when passing through the heat dissipation plate 4, and the heat dissipation plate 4 transmits the heat to the surrounding environment. While the heat emitted by the culture medium in the cabinet 1 is discharged, the output shaft of the motor 311 drives the support rod 313 and the placing frame 32 to rotate through the rotating plate 312, so that the plurality of culture media can be uniformly cooled as much as possible, and the quality of the culture medium is not affected by the too fast or too slow cooling speed.

[0043] In addition, the temperature of the culture medium is detected in real time through the temperature sensor 6, and the controller adjusts the output power of the first cooling fan 211 and the second cooling fan 212 according to the difference between the temperature of the culture medium and the target cooling temperature.

[0044] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
