Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a palm-sized centrifuge with a heat dissipation function. Background Art

[0002] A handheld centrifuge will generate a lot of heat during centrifugal experiments. If the heat cannot be dissipated in a timely and effective manner, the temperature of the device will continue to rise, which may cause the device to overheat and affect the experimental results or even damage the device. Therefore, the handheld centrifuge needs a radiator to help dissipate internal heat and keep the device within a suitable operating temperature range. The heat dissipation function of the radiator can effectively reduce the temperature of the device, improve the performance stability of the device, extend the service life of the device, ensure the accuracy and reliability of the experimental data, and thus ensure the smooth progress of scientific research;

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN216988112U) discloses a handheld centrifuge, which belongs to the field of centrifuge technology, and includes a dust cover and a centrifuge main box, the dust cover is connected with a sliding device; the sliding device is connected with an insert ring; the side wall of the centrifuge main box is connected with an insert rod for the insert ring to be installed; the side wall of the centrifuge main box is connected with a stop device for fixing the insert ring after the insert ring is installed with the insert rod, and the stop device is located directly below the insert rod; the insert rod, the stop device and the sliding device are all located in the same vertical direction. When the dust cover is buckled with the centrifuge main box, the user only needs to make the insert ring install the insert rod and use the stop device to fix the insert ring, which increases the buckle firmness of the dust cover and the centrifuge main box, effectively reduces the probability of the dust cover being opened by mistake, and thus effectively extends the service life of the handheld centrifuge;

[0004] However, in this patent, no heat dissipation device is provided. Excessive temperature will cause the temperature of the internal components of the device to be too high, thereby reducing the performance of the centrifuge. Continuous high temperature will damage the components and circuits of the device and shorten the life of the device. In addition, when the device is cooled, noise will be generated. Therefore, the utility model proposes a handheld centrifuge with heat dissipation function. Utility Model Content
