Description

The utility model relates to devices used to temporarily provide a reduced temperature in the volume of the working chamber, in particular, to maintain thermal conditions during the transportation of biological objects.

Thermal container bag is known from the field of technology [RU 2330220. Thermal container bag. Authors: Gryadnov A.I., Rakov I.V., Rodionova I. B., Budnikova L. B. IPC F25D 3/08, B65D 81/38. Application No. 2006141534/12, November 27, 2006, publ .: 07/27/2008 in bulletin. No.21] the main element of which are cold elements using the phase transition principle.

The disadvantage of this design is the possibility of leakage of the working substance from the coolant element in case of damage, as well as the disposability of the phase transition, which requires the return of the working substance to its original state for further operation of the thermal container.

Authors: Gallyamov F.N., Kamaletdinov P.P., Kinzyagulov R.F., Khairullin R.M. IPC F25D 3/14, F25D 11/00. Application No. 2011126804/13, 06/29/2011, publ .: 10.10.2013 in bul. No. 28], comprising a housing with thermal insulation, a lid with a seal and cold batteries, an inner container with thermal insulation and a lid with a seal. In the cavities between the walls of the housing and the inner chamber there are cold accumulators with an air gap. The inner chamber is made with the possibility of alternate air exchange with the environment or the cavity between the walls of the housing and the inner chamber through ducts with integrated valves that are connected to a temperature sensor, bellows or bimetallic spring placed in the inner chamber.

The disadvantage of this design is the constructive loading of the presented thermal container.

Known thermal container [patent RU 2235254 C2. Container for storing and transporting fish in a preservation medium. IPC F25D 3/06, А23В 4/06. Application No. 2002119794/12, 07.22.2002, publ .: 03/27/2004 in Byul. No. 9], containing a closed container with a bottom, front, rear and side walls, a lid, openings, a closed container made in the form of a body with a lid, one-piece of food-grade two-layer polyethylene, an aluminum foil layer is laid between the inner and outer layers of the body walls and the lid and a layer of expanded polystyrene.

In this case, the thermal conductivity of polyethylene is 0.48 W / mK, the thermal conductivity of aluminum foil is 221 W / mK (aluminum foil only reflects thermal radiation well), the thermal conductivity of polystyrene foam is 0.052 W / mK. Thus, the thermal conductivity of the insulating materials used is in the range of 0.48 W / mK to 221 W / mK, which indicates a rather high value of thermal conductivity and low thermal insulation in general. The specified method of attaching insulation materials ("laid between the walls") is not reliable.

The technical result of the proposed utility model is to improve the performance characteristics of the thermal container due to the use of materials with enhanced insulating properties and more reliable attachment.

The technical result is achieved by the fact that the thermal container, made in the form of a hollow parallelepiped with a lid made of plastic, contains a heater penoplex [http://www.penoplex.ru], cork substrate and polyethylene foam.

To the inner walls, bottom and lid of the thermal container, foam plastic plates are attached to the dimensions of the walls with polyurethane or polymeric glue, and cork backing is attached to the polystyrene or polymeric glue with polyurethane or polymeric glue. The polyethylene foam on the side of the working chamber is closed with food plastic plates to facilitate sanitary and hygienic maintenance of the working chamber of the thermal container.

Cork substrate has the following properties:

- low thermal conductivity of 0.043 W / (m * K);

- easy form recovery after compression or torsion, bending;

- water resistant;

- not afraid of alkalis and other chemically active substances;

- does not electrify, does not accumulate static electricity;

- not afraid of ultraviolet radiation and does not miss it;

- preservation of all its properties at negative temperatures;

- complete environmental friendliness and hypoallergenic;

- natural antiseptic;

- reducing the level of radioactive radiation, as well as isolation from the harmful effects of technopathogenic zones. [http://strport.ru/izolyatsionnye-materialy/tekhnicheskaya-probka-osobennosti-materiala-kharakteristiki-i-primenenie].

The polymer or polyurethane glue used for fixing insulation materials ensures a reliable and at the same time elastic connection of the materials being glued, the adhesive layer created at the same time has a thermal conductivity of 0.029 W / mK.

The cork substrate has a coefficient of thermal conductivity of 0.043 W / mK, used extruded polystyrene foam 0.03 W / mK, polyethylene foam 0.031 W / mK, adhesive layer 0.029 W / mK. Thus, the coefficient of insulation materials of the inventive thermal container is in the range from 0.029 W / mK to 0.043 W / mK.

Thus, in the inventive thermal container, the coefficient of thermal conductivity is lower than that of the considered analogues. In addition, adhesive bonding of insulation materials is quite elastic, which increases the service life of the product.

On the basis of the above, it is possible to assert that the performance of the thermal container is increased by using the insulation foam penoplex inside the thermal container, the cork substrate as a material with enhanced thermal insulation properties, and attaching the foam plastic plates and the cork substrate using glue as a more secure fit.

The device of the thermal container is shown in the figure in the figure where 1 is the outer wall of the thermal container, 2 is the foam plate plate, 3 is the cork substrate, 4 is polyethylene foam, 5 is the inner wall of the thermal plastic container.

The utility model can be successfully applied in the manufacture of thermal containers for transporting biological objects.
