Description

A kind of low temperature insulation box

technical field

The utility model relates to a package, in particular to a low-temperature incubator capable of storing products at low temperature.

Background technique

The earliest incubators appeared in the food delivery industry. At that time, there were various insulation tools, such as iron cabinets that were useful for welding by yourself, white foam boxes that were wrapped with yellow tape, or rattan baskets that put cotton blankets, etc., and so on. These devices are not only bulky and inconvenient to carry, but also unhygienic and unattractive.

With the continuous innovation of the incubator in the food delivery industry, the physical and functional progress of the incubator has finally been completed. Due to the portability of the bag and the novelty of the style, the incubator has quickly become popular all over the country in just a few years after it appeared. , especially in Beijing, has become a must-have for the catering industry. Nowadays, incubators have been used in all walks of life. At the same time, the requirements for incubators are getting higher and higher. When the products that need to be insulated have higher temperature requirements and need to be transported for a long time, the current incubators often cannot meet the requirements. To meet the requirements, and there is no timely protective measures for the box, resulting in product deterioration, sometimes resulting in irreparable losses.

Contents of the invention

In order to make up for the deficiencies of the prior art, the utility model provides a low-temperature incubator that can be stored at low temperature for a long time and can effectively control emergencies.

The utility model is achieved through the following technical solutions:

A low-temperature incubator, comprising a box body and a box cover, the box body is divided into an inner tank and an outer shell, the inner tank can be separated from the outer shell and can be taken out from the box body; the inner tank is divided into three parts, namely Sides, bottoms and separation strips; the shell is divided into inner and outer layers.

On the basis of the existing low-temperature incubator, the utility model adds a stainless steel liner which can be replaced freely, and the special structure and material in the liner can respond quickly in case of an emergency.

The unique technical scheme of the utility model is:

Water, ammonium chloride and white phosphorus are respectively filled in the side, bottom and separation zone. The ignition point of white phosphorus is very low. When it reaches a certain temperature, violent friction can spontaneously ignite, and then the side and bottom edges form a path. The combination of water and ammonium chloride instantly absorbs a large amount of heat, making the inside of the box instantly return to a low temperature environment, ensuring the product the quality of.

Laminated paper is used on the left and right sides of the divider. It is waterproof, but also burns off when the white phosphorus spontaneously ignites, allowing the sides and bottom to form pathways.

The inner layer of the shell adopts vacuumized double-layer glass, and the outer layer is PE insulation material. Vacuum can completely isolate heat radiation, and glass itself is a poor conductor of heat. The inner layer of the shell has the effect of heat insulation. In addition to heat insulation, the PE insulation material of the outer layer has good compression and wear resistance. The characteristics increase the durability of the low temperature incubator.

The box cover and the shell adopt the same structure and material, which can ensure the effect of heat preservation from all sides of the low-temperature incubator.

The beneficial effects of the utility model are: in normal use, the double-layer insulation design of the shell can ensure the low temperature environment in the box to the greatest extent, and will not be affected by the outside; If the shell is damaged, or the temperature of the external environment suddenly rises, the low temperature incubator will respond immediately to minimize the loss. The separate design of the inner tank and the outer shell allows the inner tank to be replaced after a special reaction, reducing the cost.

Detailed ways

Accompanying drawing is a kind of concrete embodiment of the utility model. This embodiment is a low-temperature incubator, including a box body 1 and a box cover 7. The box body 1 is divided into an inner tank 2 and an outer shell 3. The inner tank 2 can be separated from the outer shell 3 and removed from the box body 1. and divided into three parts, namely side 4, bottom 6 and separation strip 5; said side 4, bottom 6 and separation strip 5 are filled with water, ammonium chloride and white phosphorus respectively. The left and right sides of described separating belt 5 use coated paper. The shell 3 is divided into inner and outer layers, the inner layer adopts vacuumized double-layer glass, and the outer layer is PE insulation material. The box cover 7 and the shell 3 adopt the same structure and material.

First conduct a static test, add 3 packs of frozen medical ice packs and a wireless temperature probe into the low-temperature incubator, then close the lid of the box, seal it, and let it stand at room temperature for 72 hours, open the box, and find 3 packs The ice packs were completely melted, and the data of the temperature probe was exported, and it was found that no data higher than -6°C appeared, and the static test was successful; then the dynamic test was carried out, and 3 packs of frozen medical ice packs and a wireless temperature probe were also placed Put it into a low-temperature incubator, seal it, put the low-temperature incubator in an environment of 40°C, and continue to vibrate with an oscillator, take it out after 24 hours, open the low-temperature incubator, and find that the ice pack has melted, but the internal temperature is obviously low, and the inner tank There were still ice crystals on the wall. The temperature probe was taken out and the data was derived. It was found that the temperature exceeded 0°C at a certain moment, but the temperature dropped instantly, and the temperature difference was huge. It shows that the protective measures are effective, and the effect of the low-temperature incubator is obvious.
