The invention relates to a heating device and can be used for shrinking products, sealing the joints of cables and in other processes for heat treatment of products.

A device for heat treatment of products [1], which contains a hollow chamber with evenly spaced around the perimeter inside its walls the radiation sources. The surface of the camera housing is made with a longitudinal slot to form a processed surface.

However, e the measures and cannot be used for heat treatment long enough thin products.

The objective of development is to create a tool for local heating products, in particular, is very extensive, such as cables, as applied to the transactions sealing using a heat-shrinkable elements of the type HERE (heat pipes).

The invention consists in the execution of a device for heat treatment of products in the form of a miniature infrared heater, in which a special way interconnected housing-reflector and emitter.

As emitters used halogen incandescent lamp type KGM. Lamps of this type represent the flask with a diameter of about 10 mm and about 15 mm, inside which there is a body glow (spiral). The contact spiral vpaivaetsja in the lamp base through the molybdenum foil spacers and end pin conclusions. These elements are extremely sensitive to overheating and do not allow continuous operation at temperatures above 300aboutWith, otherwise the bulb burn out as if from the outside.

Housing is a reflector, which is made hollow to form thermoablative surface has a slot, the radiation sources are located inside the reflector. The relative positions of the reflector and lamp TM, resource lamps will be reduced. Therefore, in the device for shrinking products used a special form of the cartridge which securely screens are sensitive to overheating of the lamp base. To the cartridge absorbed perhaps less radiant flux, it has a mirror surface and is made of material with good reflective properties, for example, aluminum. The reflecting surface of the reflector is also made mirror. Housing is a reflector, which may be made annular, rectangular, triangular, depending on the shape of workpiece attached to the handle, which is a toggle power.

The device has small dimensions, so you can work inside the units or in other cramped conditions. In the process, it is possible manipulation of irradiation. The device enables visual control of the entire zone of irradiation due to the small width of the body of the reflector and by a certain arrangement of radiation sources.

The drawing shows the device for shrinking products with the annular housing-reflector.

The device includes a housing reflector with heat sink 1, N sources emission is s from radiation and by contact with the body eliminates overheating of the cap. The arm 4 with the switch 5 is attached to the housing which has a slot 6 to enable coaxial installation of the device on the product.

The device operates as follows.

It is installed on the heat-shrinkable product, and then turns on the switch 5 at the handle 4. Radiation from sources of radiation reflected from the inner surface of the shell is divided by the circular area on the surface and warms it. The shrinkage process is monitored visually through the gap between the casing and the product, and after reaching effects of shrinkage device is moved along a product to proceed along the length of the product. In the process, there is an intensive heating of the cartridge, which is attached to the radiation source.

However, thanks to the heat transfer from the cartridge 3 to the body of the reflector 1 and the subsequent dissipation of the absorbed body-reflector energy in space, and also due to the fact that the cartridge protects the base of the lamp from direct exposure, overheating of the cap and premature failure of the lamps does not occur.
