Abstract

Aluminum plate (1) for heat transfer, characterized by that the 420 mm × 420 mm aluminum plate has a thickness of 1-3 mm to ensure optimal thermal conductivity while maintaining low weight, and is provided with integrated fastening elements such as rivet nuts or threaded inserts (2), Fixation is achieved by stainless steel screws for connection to electrical heating or induction elements.

Description

The adapter (aluminum plate 1-3 mm) with the associated attachment for heating elements is designed for heating the heatable thermal pockets up to 90 degrees and holds them in the desired temperature for the further transport of warm food to the consumer constant. For the transport of the thermal pockets, different vehicles / transport means can be used, in which an adapter for connecting pockets is installed and thus keeps the ideal temperature in the pocket constant. The thermal bag is connected automatically on the shelf to the 12 volt network or induction device via the adapter units installed there. The adapters installed in the thermal pouch are heated to an ideal and constant temperature of up to 90 degrees and maintained in the pouch at the bottom of combustion. An exemplary embodiment of the invention is explained on the basis of the sketch.

The invention enables uniform heating of the thermal pouch during the transport of warm food to the end user.Prior ArtThe transport of warm food requires reliable solutions for keeping the temperature, in particular when using different transport means. Previous systems are based on passive insulations or active heating systems which are not standardized or are not universally usable.Object of the InventionThe object of the present invention is to provide an improved device which ensures efficient and uniform heating of a thermal pouch during transport. The adapter should be compatible with both induction and conventional electrical heating systems and should enable a secure fastening of the heating elements.Solution of the ProblemThis object is achieved by an adapter with fastening elements which can be integrated into the thermal pocket or fitted subsequently. The adapter is designed such that it automatically connects to a power source as soon as the thermal bag is placed in a transport vehicle or a corresponding shelf.The invention comprises in particular:• an adapter unit for receiving a heating element,• an electrical interface for automatic connection to an external energy source (e.g. 12V connection or induction field),• a fastening device which ensures secure fixing of the heating element within the thermal pocket,• Temperature control allowing the pocket to be heated up to 90°C.The attachment of the adapter to the bottom of the thermal pouch provides uniform heat distribution while thermal insulation prevents burns.Advantages of the Invention• Automatic connection to a power source when placing the bag in the transport means• Constant and uniform heating of the thermal pouch• Compatibility with various heating systems (induction or 12V connection)• Secure Holding of the Heating Element by the Adapter Device• Efficient temperature control to avoid overheating or energy lossBrief Description of the DrawingsAn exemplary embodiment of the invention is explained on the basis of the attached sketch. The drawing shows a perspective view of the thermal pouch with the adapter installed and the mechanical and electrical connection to the heating system.
