Abstract

FIELD: heating.

SUBSTANCE: convector with an infrared heating element can be used to heat indoor premises for various purposes: offices, residential buildings, industrial facilities. Convector with the infrared heating element consists of a metal body with fins of cooling in the form of a round tube, the ends of which are covered with plugs, the inner surface of the pipe and plugs is treated with a coating that absorbs the thermal radiation of the infrared spectrum to the maximum, an electric linear infrared heating element is installed in the center of the circular tube, which heals the heater body from the inside with thermal radiation of the infrared spectrum, and also by heating the air with the heated surface of the heating element itself. All the beams of the infrared spectrum, without the use of a reflector, are uniformly directed to the surface with a coating, which absorbs the thermal radiation as much as possible at an angle of 90 degrees, linear infrared heating element is in a completely enclosed metal casing in the form of a round tube with fins of cooling.

EFFECT: provides a highly efficient heating convector with low power consumption; convector runs noiselessly, quickly heats up, is economical in use, does not burn oxygen in the room, is fireproof, is resistant to falling, is suitable for repair.

Description

The invention relates to heating equipment, namely to electric heaters for enclosed spaces.

State of the art

The closest analogue found is a film infrared heater, designed for underfloor heating:

infrared film Heat Plus SPN - South Korea, manufacturer "Seggi Century Co. Ltd";

XiCAXT infrared film - South Korea, manufacturer of RexVa Co. Ltd ";

principle of operation - a film infrared heater is laid on a coating that reflects thermal radiation (for example, foil), a material is laid on top that will be heated by infrared radiation and convectively heat the air;

coincident features - this technical solution coincides with the claimed invention in that a hidden infrared heating element is also used, the room is heated by convection.

Disclosure of invention

A convector with an infrared heating element consists of a metal body with cooling fins in the shape of a round pipe, the ends of which are closed with plugs, the inner surface of the pipe and plugs is treated with a coating that absorbs the thermal radiation of the infrared spectrum as much as possible, an electric linear infrared heating element is installed in the center of the round pipe, which is inside heats the heater case by thermal radiation of the infrared spectrum, and also by heating the air with a heated surface of the heating element, all the infrared rays, without the use of a reflector, are uniformly directed to the surface with a coating that maximally absorbs thermal radiation at an angle of 90 degrees, the linear infrared heating element is located along its entire length at the same distance from the pipe surface, which provides highly efficient fast heating low power convectors.

Convector temperature regulation is possible by connecting it to the mains via a power regulator. Switching the convector on and off from the mains is done by a switch.

Brief Description of the Drawings

The diagram shows the convector housing (1), the cover of the housing (2), the holder of the heating element (3), an infrared heating element (4), a switch (5) with a network connection diagram.

The implementation of the invention

For an example embodiment of the invention, the following equipment and materials will be required:

- a round metal pipe for the manufacture of a convector body;

- a sheet of metal for the manufacture of cooling fins;

- a laser machine for cutting metal;

- semi-automatic welding machine;

- body cap - 2 pieces;

- 3D printer for printing the plugs of the case;

- a metal strip for the manufacture of a holder for a heating element;

- linear infrared heating element;

- pliers;

- Bulgarian with a cutting disc for metal;

- heat resistant cable;

- linear infrared heating element;

- switch.

We make convector body parts:

- cut the cooling fins of the convector body on a laser machine;

- weld the cooling fins to the pipe by semi-automatic welding.

We make the holder of the heating element:

- grinder cut two identical blanks from a metal strip;

- with pliers we bend the end of the parts at an angle of 90 degrees for attachment to the convector body (2);

- to install the heating element, we prepare the other end of the holder (3);

- we weld the end of the holder (3) bent at 90 degrees to the convector body (l) taking into account the length of the infrared heater (4).

Housing caps:

- we print out the caps of the body (2) on a 3D printer, the walls of the caps should fit snugly against the convector body. There should also be a hole for connecting the cable to the heating element.

Coloring details:

- we apply on the inside of the body (1) a black matte heat-resistant paint;

- we put on the inside of the two caps of the housing (2) a black matte heat-resistant paint.

Convector assembly:

- install the infrared heater (4) on the holders (3), connect the heat-resistant cable (the method of installation and connection depends on the type of infrared heater);

- we conduct the cables through the holes in the caps of the body (2) and install the caps on the convector body (1);

- install the switch (5);

- we make connection to the power supply network.

Device operation:

To start the convector, you need:

- connect the power supply to the infrared heater (4) using the switch (5), after turning on the infrared heater, the temperature of the convector body (1) and the plugs of the body (2) increase, as a result of which the external air is heated by convection.

To stop the convector, you need:

- turn off the power supply using the switch (5), after turning off, the temperature of the convector case (1) and the plugs of the case (2) gradually decrease to the ambient temperature.
