Problems solved by technology

However, when the air-cooled heat dissipation method is used, two problems are usually encountered: 1. The volume of the air duct is relatively large compared with the size of the Peltier element, which is difficult to arrange for medical equipment with a small overall volume
2. If the fan type is too large, it will cause noise when the instrument is working. If the fan type is too small, the cooling efficiency will be low and it will not be able to meet the heat dissipation requirements.

Abstract

The invention provides a method, a device, a medium, equipment and an instrument for improving the refrigeration efficiency of a Peltier. The method for improving the cooling efficiency of the Peltier comprises the steps that the hot surface temperature and the cold surface temperature of a Peltier element are obtained in real time; the hot surface of the Peltier element is heated or cooled by controlling the Peltier element to work or stop working, so that the temperature of the hot surface is controlled between a preset temperature upper limit and a preset temperature lower limit until the temperature of the cold surface reaches a target temperature; wherein the preset temperature lower limit is dynamically adjusted according to the working duration and the stopping duration of the Peltier element in the previous period. The cooling efficiency of the Peltier element is improved, and the heat dissipation requirement of the Peltier element is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of Peltier refrigeration, in particular to a method, device, medium, equipment and instrument for improving the efficiency of Peltier refrigeration. Background technique [0002] In the field of medical equipment, when designing detection instruments, it is usually necessary to consider storing reagents in a low-temperature and constant-temperature environment. Because the cooling power required is not high, Peltier thermoelectric refrigeration is usually used as an ideal cooling method, which can achieve Pa The cooling effect of the cold surface temperature of the Eltier element is much lower than the ambient temperature. [0003] The principle of Peltier refrigeration is the Seebeck effect. When there is no heat exchange between the Peltier element passing a certain current and the outside world, the cold and hot surfaces maintain a certain temperature difference after stabilization. At this time, if the ...
