Description

Technical Field

[0002] With the improvement of my country's medical level, the quality assurance of each link of drug transportation needs to be continuously strengthened, especially when transporting vaccines, human organs and other medical products with high temperature control over long distances, which are extremely easy to be damaged. Professional technical equipment is needed to ensure the quality and safety of drugs. Most of the medical storage and transportation boxes of the original technology use cold storage bags for transportation, which have a short shelf life and greatly limit the long-distance transportation of drugs. Medical storage and transportation boxes using semiconductors have relatively high construction costs. Although they can meet the needs of long-distance transportation, their temperature control is not accurate enough, and the high-power heat dissipation required at the hot end requires additional energy consumption, resulting in energy waste.

[0003] Existing medical storage and transportation boxes have large temperature fluctuations and short battery life, making it difficult to guarantee the quality of medical products, and thus difficult to transport vaccines, organs and other medical products. Traditional semiconductor refrigeration medical storage and transportation boxes have limited distances between the hot and cold ends of traditional semiconductors, which will generate a large amount of internal heat transfer due to the Fourier effect, greatly reducing the working efficiency of semiconductors. They can only be cooled with high-power heat dissipation, resulting in energy waste, unstable temperature control, and the inability to share resources in real time, keep abreast of the status of medical products and remedy them in a timely manner. As a result, it is difficult to guarantee the quality of medicines during transportation, and the damage rate of medicines has risen sharply.

[0004] Therefore, it is necessary to provide a high-precision medical storage and transportation box based on a new dual heat sink structure to solve the above technical problems. Utility Model Content

[0015] 1. This device adds an intermediate conductor between the thermoelectric arms of the traditional semiconductor to form a new multi-element heterogeneous thermopile structure. Compared with ordinary semiconductor cooling sheets, this connection method reduces the negative impact of the Fourier effect and improves the thermoelectric conversion efficiency. Compared with traditional thermoelectric elements, the new multi-element heterogeneous thermopile structure has significantly higher performance under both stable and pulsed currents.

[0026] Specifically, the distance between the hot and cold ends of traditional semiconductors is limited, and a large amount of internal heat transfer will be generated due to the Fourier effect, which greatly reduces the working efficiency of the semiconductor. To solve this problem, an intermediate conductor is added between the thermoelectric arms of the traditional semiconductor to form a new multi-heterogeneous thermopile structure 1. Compared with ordinary semiconductor refrigeration sheets, this connection method reduces the negative impact of the Fourier effect and improves the thermoelectric conversion efficiency. Compared with traditional thermoelectric elements, the new multi-heterogeneous thermopile structure 1 has significantly higher performance under both stable and pulsed currents. This device can select P and N junctions of different sizes and conductors of different diameters for connection and use according to the different cooling capacities of different medicines. Trapezoidal P and N junctions can be selected at the hot end. Compared with traditional P and N junctions with equal cross-sections, the volume heat of variable cross-section P and N junctions is reduced, the cooling capacity is increased, the maximum thermal stress that the legs can withstand is greatly increased, and the cost is relatively reduced. It is then combined with the transformer and control module 6 to achieve different cooling effects;

The temperature is read by the thermocouple 16. When the temperature sensed by the thermocouple 16 is higher than the preset value, the voltage transformation and control module 6 adjusts the voltage of the new multi-component heterogeneous thermopile structure 1 to control the refrigeration of the new multi-component heterogeneous thermopile structure 1.
