Heat absorption and heat preservation system for refrigeration heat preservation box and refrigeration heat preservation box

Abstract

The invention discloses a heat absorption and heat preservation system for a refrigeration heat preservation box. The heat absorption and heat preservation system comprises a heat preservation body, aheat preservation cavity and a semiconductor refrigerator, wherein the semiconductor refrigerator is used for containing materials needing refrigeration and heat preservation, and threads are arranged at an opening of the heat preservation body; the heat preservation cavity comprises a first heat preservation cavity and a second heat preservation cavity which are in butt joint; the second heat preservation cavity comprises a rear cover, and the first heat preservation cavity is sealed with the opening part of the heat preservation body through the threads; and the semiconductor refrigerator is suspended in a closed space formed by the heat preservation body and the heat preservation cavity. According to the heat absorption and heat preservation system, heat conduction in a heat preservation body material can be effectively reduced, the sealing efficiency is improved, and meanwhile, the refrigeration heat preservation box is compact in overall structure, reasonable in layout of all components and convenient to carry.

Description

technical field [0001] The invention relates to a heat absorption and heat preservation system for providing a special environment for stored materials, in particular to a heat absorption and heat preservation system for a refrigeration heat preservation box. Background technique [0002] Medicines are substances or preparations for the prevention or treatment or diagnosis of diseases in humans and livestock. Modern medicines are mostly refrigerated medicines. Some medicines need to be stored in a lower environment, such as insulin. Insulin is a commonly used medicine stored at low temperature. At present, when insulin is carried, it is often inactivated due to high storage temperature, which affects the use of patients. For another example, after skin burns, some biological dressings and cytokines are generally used to spray the wound in clinical practice, so as to promote the rapid healing of the wound. However, the drugs containing the above-mentioned biological dressin...

AI Technical Summary

Problems solved by technology

However, the drugs containing the above-mentioned biological dressings and cytokines need to be stored in a low temperature environment to ensure their activity and efficacy, otherwise the drugs will fail and even produce some harmful components

In some special or emergency environments, it is necessary to carry the above-mentioned drugs containing biological dressings and cytokines for rescue. Due to the lack of corresponding refrigeration environment, it is difficult to carry and store the above-mentioned drugs, which affects emergency treatment.

[0003] There are two kinds of technical methods for the existing portable low-temperature storage of medicines. One is that low-temperature auxiliary materials such as ice cubes and medicines are placed in a heat preservation device, and the other is a large-volume electronic refrigeration refrigerator that depends on the power supply of a car or a portable power supply. (The refrigerating body is located on the side or bottom of the refrigerator. Once the power is cut off, the refrigerating body will immediately start heating the inside of the refrigerator.) The insulation structure adopted by the two technologies is foam insulation technology. When the ambient temperature exceeds 20 degrees Celsius, the temperature difference The heat preservation effect with a change of less than ten degrees is only about six hours. If you carry medicines that need to be stored at low temperature, due to portability requirements, the volume of the heat preservation device is limited within a certain range, so the foam insulation effect is even worse, and it is difficult for doctors and patients to go out. Carrying medicines is a great inconvenience

Large volume, poor heat preservation, and unreasonable refrigeration / radiation structure constitute the three major defects of the existing technology, and there is also the problem of high cost
