Description

Field of technology

The utility model relates to electric heating and can be used to create warm floors in residential, office and industrial premises. In addition, it can be used to heat industrial facilities such as gas holders, tanks and other containers where high-quality heating with insulation and uniform heat transfer to a large area is required.

State of the art

Currently, heating elements for underfloor heating are intensively used, including heating mats, heating cables and infrared films.

Carbon film flooring is known from the state of the art

(https://www.teploluxe.ru/articles/teplyy-pol/karbonovyy-teplyy-pol-plenochnyy-i-sterzhnevoy-tekhnologii-montazha/?ysclid=m8zosnvq61890300455). The heating element of the film floor is carbon or a mixture of carbon and graphite, which is applied to heat-resistant polypropylene. To protect the heating element from scratches and other negative effects, it is sealed on both sides with a three-layer film. Electricity is supplied through copper buses that contact the heating element through a silver coating, which eliminates the formation of sparks. The sections are connected in parallel, so if one of them fails, the system will continue to work.

The disadvantages of this solution are high heat loss, complexity of installation, and the need to use additional materials for insulation and heat distribution.

A similar infrared segmental warm floor (Patent RU No. 147449 U1, IPC F24D 3/00, published 11/10/2014) is known, which consists of a grid consisting of identical segments, each segment includes a heating element. The heating element, made of insulated carbon thread, is located and fixed on the surface of the fiberglass grid, and is connected in parallel with conductive tinned copper wires with silicone insulation, located along the edges of the grid.

The disadvantage of this technical solution is the use of a fiberglass mesh, which limits the possibility of installation on the surface, i.e. it is necessary to use a special substrate. Installation of such a floor requires additional operations, which increases the complexity and cost of using the device.

Disclosure of a utility model

The task that the claimed utility model is aimed at solving is the creation of a reliable design that combines the functions of a heater and thermal insulation.

This problem is solved by achieving the technical result of the claimed utility model, which consists in increasing the efficiency of heat transfer and reducing heat loss.

The technical result is ensured by the design of the active heating substrate of the roll type, which contains a base with identical sections located on it with a heating element made of carbon thread in silicone insulation and connected in parallel to the current-carrying copper tinned cores in silicone insulation, located along the base. The base is made of metallized foamed polypropylene and contains channels in which the heating elements and current-carrying cores are laid flush with the surface of the base, and a metal foil is attached to the base from the side of the placement of the heating elements.

The base is made of metallized foamed polypropylene, which provides improved thermal insulation and prevents heat leakage in the opposite direction.

The metal foil performs the functions of uniform heat distribution, shielding of electromagnetic radiation and grounding.

The utility model is illustrated by a drawing.

The figure shows a general view of the active heating substrate.

The base 1 of the active heating pad of the roll type is made of metallized foamed polypropylene and consists of identical sections 2. In each section 2, a heating element 3 made of carbon thread in silicone insulation is built in flush with its surface. On the side where the heating elements 3 are located, a metal foil 4 is attached to the base. The heating elements 3 are connected in parallel to the conductive cores 5, which are also located in channels flush with the surface of the base 1. The active heating pad is made in the form of a roll, from which it is easy to cut the required number of sections to cover large areas. Each section 2 has autonomous heat generation and operates independently, which ensures that the system remains operational if individual elements are damaged.

The active substrate is mounted as follows.

The roll is rolled out onto the prepared surface and the required number of sections 2 is cut off from the roll in accordance with the dimensions of the room or object. The terminals of the current-carrying wires 5 are connected to the thermostat. The floor covering (laminate, parquet or other) is laid directly on the substrate without the need for additional preparation, which simplifies the installation process.

Operation of the device

The substrate is connected to the power supply system via a thermostat, which allows you to set the desired temperature. Voltage is supplied to the conductive wires, which supply power to the heating elements 3. When electric current passes through the heating element 3, electrical energy is converted into heat.

Due to the combination of essential features, improved thermal insulation is ensured, preventing heat leakage in the opposite direction, and uniform heat distribution over the entire area of the section.

Autonomous sections allow the system to remain operational even if one of them is damaged, which makes it reliable and durable. Easy installation and the ability to lay floor coverings without additional preparatory work make this underlay a universal solution for residential and industrial premises.

The utility model can be manufactured in the conditions of domestic industry using modern equipment.
