Abstract

The application belongs to the technical field of biochemical analyzers, and provides a constant-temperature module, a constant-temperature control method and a full-automatic dry biochemical analyzer. The constant-temperature module comprises a composite heating layer, a heat-conducting substrate, a temperature sensing array and a heat dissipation layer. The composite heating layer comprises multiple groups of independently controlled heating units, and the heating units are made of carbon nanotube film and metal alloy composite material. The heat-conducting substrate is attached below the composite heating layer, and the heat-conducting substrate is made of high-heat-conducting ceramic material. The temperature sensing array comprises multiple temperature sensors, and the temperature sensors are uniformly distributed on the surface of the heat-conducting substrate. The heat dissipation layer is arranged above the composite heating layer, and the heat dissipation layer comprises a micro fan and a semiconductor refrigeration sheet. The application can improve the precision and efficiency of constant-temperature control, and ensure that the biochemical analyzer can maintain stable reaction temperature during sample detection.
