[0053] See also Figure 9-10 A heat conducting sheet 17 is also provided in the heat conducting cavity. The heat conducting sheet 17 is made of metal and is connected to the first plate 15.

[0057] In this example, the heat dissipation assembly includes a heat dissipation cavity 2 and an air induction member 3. The heat dissipation cavity 2 is connected to the shell 9. The heat dissipation cavity 2 has a heat dissipation air duct. The heat dissipation cavity 2 is provided with an opening that is connected to the heat dissipation air duct on the side away from the shell 9. The opening is connected to the atmosphere, and the air induction member 3 is located in the heat dissipation air duct. When the temperature inside the shell 9 is higher than the target temperature, the air induction member 3 is turned on, and the controller outputs a cooling command to control the relay system to drive the refrigeration member 12 to work for cooling, and opens the air induction member 3 of the external heat dissipation air duct to dissipate heat to the outside. At the same time, the blowing member 13 inside the shell 9 works to blow cold air to the entire shell 9 until the temperature inside the shell 9 reaches the target temperature and stops. When the temperature inside the shell 9 is lower than the target temperature, the air induction member 3 does not work.

[0058] See also Figure 1-5 In some embodiments, the heat dissipation cavity 2 includes a first cavity, a second cavity, and a third cavity that are connected to each other.

The first section 25 is located above the second section 26. The first section 25 is connected to the second cavity. The first section 25 is narrow at the top and wide at the bottom, that is, the width of the first section 25 gradually increases from its upper end to the lower end. The second section 26 is surrounded on all sides and penetrated in the vertical direction. The air inducing member 3 is preferably located in the second section 26.

[0060] See also Figure 3 The first cavity includes a first part 21 and a second part 22 that are connected. The first part 21 and the second part 22 are horizontally arranged (such as left and right arrangements). The first part 21 is connected to the second cavity.

[0061] See also Figure 3-4The second cavity includes a substrate 23 and a cover 24. The substrate 23 is connected to the shell 9. The substrate 23 serves as a side wall of the shell 9, and one side of the substrate 23 faces the inside of the shell 9; the cover 24 is connected to the substrate 23. The cover 24 is a straight U-shape. The substrate 23 and the cover 24 are connected to form a cavity that is enclosed on all sides and penetrates in the up and down directions. The other side of the substrate 23 faces the cavity.

[0062] In a preferred embodiment, a heat sink 4 is provided in the second cavity and is visible from the opening of the first cavity. The heat sink 4 is made of metal and has the advantage of dissipating heat within the housing 9. Preferably, multiple heat sinks 4 are provided, and the multiple heat sinks 4 are arranged in parallel with gaps between adjacent heat sinks 4.

[0063] In a preferred embodiment, a receiving groove is provided on the side of the base plate 23 facing the housing 9. A heat conducting strip 5 is disposed within the receiving groove. The heat conducting strip 5 is made of a metal material (preferably copper) and is disposed opposite (or in contact with) the refrigeration element 12. The provision of the heat conducting strip 5 facilitates the transfer of heat from the housing 9 to the outside when the temperature inside the housing 9 is high. Preferably, multiple receiving grooves are provided, and multiple heat sinks 4 are provided, with each receiving groove corresponding to each heat sink 4. The heat conducting strip 5 is disposed vertically and may be oval in shape.

[0064] The device also includes a controller, which is connected to the heat conduction component 1, the heat dissipation component, and the temperature probe 7.

[0065] See also Figure 15 A fixing base 6 is disposed within the housing 9, and a temperature probe 7 is mounted on the fixing base 6. The fixing base 6 comprises a base body 61 and a boss 62 protruding from one side of the base body 61. The base body 61 is square and annular, with a central hole defined in the middle thereof, and a through-hole for the temperature probe 7 to pass through defined on the boss 62. Two bosses 62 are provided, one at the upper end and the other at the lower end of the same side of the base body 61. Opposite ends of the temperature probe 7 are mounted on the two bosses 62.

[0066] The device also includes an infrared temperature sensor 20 and an alarm. Both the infrared temperature sensor 20 and the alarm are connected to the controller. The infrared temperature sensor is responsible for monitoring the temperature inside the shell 9 and transmitting the temperature result to the controller in real time. When the temperature is too high or too low, the alarm will work and the power supply can be cut off.

[0067] The temperature control principle of the cell centrifuge device in this example is as follows: the shell 9 is sealed, and the blowing member 13 inside the shell 9 is always powered on (on when powered on, off when powered off) to ensure that the air in the shell 9 flows so that the temperature is uniform. The target temperature is set on the controller, and then the controller controls the relay system to drive cooling or heating; the temperature probe 7 collects the temperature in the shell 9 in real time and transmits it to the controller. When the temperature in the current shell 9 is higher than the target temperature, the controller outputs a cooling command to control the relay system to drive the cooling member 12 to work for cooling, and opens the air induction member 3 in the heat dissipation chamber 2 to dissipate heat to the outside. At the same time, the blowing member 13 inside the shell 9 blows cold air to the entire shell 9 until the temperature in the shell 9 reaches the target temperature and stops; when the temperature in the current shell 9 is lower than the target temperature, the controller outputs a heating command to control the relay system to drive the heating member 11 to work, and the blowing member 13 inside the shell 9 blows hot air to the entire shell 9 until the temperature in the shell 9 reaches the target temperature and stops (the air induction member 3 does not work during this process). In addition, in the case of abnormal heating, the temperature switch disconnects the heating element 11 to prevent further heating when the temperature reaches its own limit temperature; in addition, the temperature probe 7 monitors the temperature inside the shell 9 and transmits the temperature detection results to the controller in real time, and controls the heat conduction component and the heat dissipation component according to the detection results.

[0068] The advantages of the temperature control device for the cell centrifuge device in this example are: by providing a heat conducting component and a heat dissipating component, temperature acquisition is more accurate, temperature control is more precise, protective measures are more complete, and there is no adverse effect on cell culture.

[0069] In another embodiment, a cell centrifuge device is provided, which includes a temperature control device for the cell centrifuge device and a centrifuge 10. The centrifuge 10 is located in the accommodating space of the shell 9. The centrifuge 10 is used for centrifugal processing of cells.
