Abstract: The present invention relates to a heat preservation shell (4) for an analyzer. At least one liquid passage (402) for conveying the liquid is embedded in a shell wall of the heat preservation shell. The liquid passage (402) is embedded in the shell wall of the heat preservation shell (4), on one hand, the liquid transported or preserved in the liquid passage is subjected to the heat preservation function of the heat preservation shell, so that the liquid transported or preserved in the liquid passage (402) maintains the preset temperature, thereby avoiding the influence of the external environment temperature on the transported liquid; and on the other hand, the space of the shell wall of the heat preservation shell is effectively utilized, the situation that various liquid pipelines are intricately distributed inside or outside the heat preservation shell (4) is avoided, thereby increasing the space utilization rate.

Abstract: The present invention relates to a liquid heater (6) for an analyzer, including a heating element (602), and at least a first liquid chamber (604) and a second liquid chamber (606), which do not communicate with each other in the heater (6), wherein at least one liquid chamber is accommodated in another liquid chamber, the heating element (602) heats the liquid in one liquid chamber, and the heated liquid heats the liquid in the other liquid chamber. In the liquid heater, the liquid in at least one liquid chamber is not in direct contact with the heating element and is indirectly heated by the heat transfer of the heated liquid, thereby avoiding the problem that corrosive liquid corrodes the heating element, and accordingly the service life of the heating element is prolonged; and on the other hand, the problem that two heaters are respectively used for heating separately, resulting in large installation volume and high cost is avoided, the volume of the liquid heater is reduced, and the cost is reduced.
