The biological sample may include blood, urine, gynecological secretions, or the like.

Referring to fig. 1 to 4, the sample analyzer includes a housing 10, a sample analyzer 20, a power supply 30, and a reagent refrigerator 40. The cabinet 10 is formed with a first heat dissipation channel 111 and a second heat dissipation channel 112. The sample analyzer 20 is disposed in the housing 10, and the sample analyzer 20 is used for analyzing a biological sample. The power supply 30 is disposed in the first heat dissipation channel 111. The power supply 30 is electrically connected to the power requiring components of the sample analysis device 20. The reagent refrigerating apparatus 40 is provided in the cabinet 10. The reagent refrigerating apparatus 40 includes a refrigerating chamber 41, a refrigerating mechanism 42, and a heat radiating mechanism 43.

In the sample analyzer of the above embodiment, the heat generated by the power supply 30 can be conducted to the air flow in the first heat dissipation channel 111 to be dissipated, and the heat generated by the reagent refrigeration device 40 can be conducted to the air flow in the second heat dissipation channel 112 to be dissipated, so that the heat generated by the power supply 30 and the reagent refrigeration device 40 can be dissipated in time, the detection accuracy of the sample analyzer is improved, and the service life of the sample analyzer is prolonged. In addition, because the first heat dissipation channel 111 and the second heat dissipation channel 112 are independent of each other, the air flow turbulence caused by the mutual influence of the air flow between the heat dissipation channels is avoided, and therefore the heat dissipation efficiency is better improved.

Referring to fig. 1 and 3, in some embodiments, the chassis 10 includes a box body 12 and a power box 13. The sample analyzer 20 and the reagent refrigerator 40 are provided in the box main body 12.
