Description

The invention relates to a power system, namely, to heat an air or liquid medium, and can be used to heat rooms or heat a liquid, such as water, for technological needs. Known heating devices (electroconvectors) containing a housing with openings for air inlet and outlet, between which inside the housing on supports of electrical insulation material there is a heater made in the form of a spiral and connected through a switch to the power supply [1. Varshavsky A.S., Volkova L.V., Kostylev V.A. etc. Domestic heating electrical appliances: designs, calculations, tests. M., Energy Publishing House, 1981, p. 111, Fig. 8].

The disadvantage of such devices is that the heater, made in the form of a spiral of high-resistance material, is heated to a temperature of 450-500 ° C or more, and this leads to the combustion of oxygen, thermal decomposition of dust and moisture with the release of harmful impurities into the atmosphere of the heated room. At the same time, the required comfortable conditions in the room are not provided, because the air quality is deteriorating: it becomes drier and unhygienic with a low oxygen content.

In addition, these devices have a large energy consumption per unit of heat generated. The amount of electricity consumed is 1.3 times more than the heat generated. Losses of electric energy take place, including due to the presence of leakage currents and insufficient purity of the materials used.

In addition, these devices have low reliability. When the spiral burns out, the electroconvector loses its working capacity, and the ends of the dangling spiral create a risk of electric shock.

Oil-filled electric radiators, widely produced by industry, are also known, containing a housing filled with transformer oil, a tubular electric heating element located in the lower part of the housing, a switch, a thermal switch, and household fittings [2. Electric radiator ERMPT-0.5 / 220 / P / Luch. Release Date August 17, 1989 Operating Instructions].

The disadvantages of oil-filled electric radiators include, first of all, the presence of an intermediate coolant - oil, which causes:

- significantly greater energy consumption per unit of heat generated in comparison with a spiral heater;

- a significantly larger mass of oil-filled electric radiators compared to electroconvectors - about 20 kg per kilowatt of power;

- great inertia, low efficiency; steady temperature occurs only 25-35 minutes after switching on;

- danger of oil overheating and leakage;

- due to the small temperature difference, the dimensions and mass of electric radiators are large.

The closest analogue in its purpose and principle of operation is a heating device [1].

The objective of the invention is to reduce electricity consumption per unit of heat generated, increase thermal power, operational reliability and efficiency of the heating device.

The stated technical problem is solved in that in a known heating device comprising a housing with holes for entering and leaving a heat carrier, a heat carrier and a heating element located inside the housing, the heating element is made in the form of an electric light source placed in a heat-generating chamber made of heat-conducting light-impermeable material .

In addition, when using air as a heat carrier, the fuel chamber is made in the form of a hollow cylinder open from the end sides.

In addition, when using a liquid coolant, the heat-generating chamber is made in the form of a hollow cylinder closed on one or two end faces.

In addition, the heating device includes a diffuser.

In addition, the heating device includes a fan.

New features that provide a solution to the problem - the heating element is made in the form of an electric light source placed in a heat-generating chamber of a heat-conducting light-proof material.

Moreover, in the case of using air as a heat carrier, the fuel chamber is made in the form of a hollow cylinder open from the end faces.

Moreover, in the case of using a liquid coolant, the heat-generating chamber is made in the form of a hollow cylinder closed on one or two end faces.

In addition, the heating device includes a diffuser.

In addition, the heating device includes a fan. Thus, the claimed invention meets the criterion of "novelty."

Since the prior art does not know the solutions having the presented set of essential features, it should be considered that the invention meets the criterion of "inventive step".

Figure 1 presents a General view of the heater. Figure 2-5 presents special cases of the implementation of the proposed technical solution.

The heater (Fig. 1) consists of a housing 1, inside which a heating element is placed, made of an electric light source - a lamp 2, placed in a heat-generating chamber 3, made of heat-conducting lightproof material. Lamp 2 through the cartridge 4 and cable 5 is connected to a power source 6.

The device operates as follows. When connected to an AC source 6, an electric light source (electric lamp) 2 begins to emit rays of the visible spectrum, which fall on the walls of the heat-generating chamber 3, made of opaque heat-conducting material, and are converted into thermal energy, that is, short light waves are converted into long thermal . Thermal energy is removed from the heat-generating surface by means of a heat carrier gaseous, for example air, or liquid, for example water. As a light source, any lamp can be used. The amount of heat generated by the device is proportional to the amount of light flux emitted by the lamp.

Samples of the inventive device are made and tested in operation. During their manufacture and in the process of trial operation, the advantages of the claimed device in comparison with the prototype were confirmed: more than 2 times reduced energy costs per unit of heat generated; fireproof; does not burn oxygen; reliable in operation; it is easy to manufacture; consists of simple components; simple and affordable to repair.

The heater consists of a housing 1, inside of which there is a heating element made of an electric light source - lamp 2, placed in a heat-generating chamber 3, made of heat-conducting material, lamp holder 4, electric cable 5, cover 7 of housing 1, cargo resistance 8, placed in the housing 9 from a heat-conducting material, a coupling 10. The cover 7 is mounted on the housing 1 taking into account the ventilation gap 11. The end side 12 of the housing 1 has ventilation holes 13. The end side 14 of the housing 9 and has ventilation holes 15.

As a light source 2, a DRL-125 lamp was used. The fuel chamber 3 is made of galvanized iron, has a cylindrical shape and is open from the end faces. The camera 3 is suspended in the housing 1 of the device using the latches 16. The housing 1 of a cylindrical shape is made of steel St.3.

By means of a heat carrier, in particular air, heat is transferred to the housing 1, which gives it to the environment. At the same time, the body over the entire length is heated to a temperature of 90-100 ° C. Since the design of the heater provides for the communication of the coolant - air with the external environment, the heating are both the outer surface of the fuel chamber, and the inner and outer surfaces of the device. The total heating surface area of this design is approximately 0.3 m ² . Power consumption 125 watts. The amount of heat generated exceeds the heat generated by a 250 W spiral type heater.

In contrast to the device described in Example 1, a diffuser is installed as a cover 7 on the housing 1. In this case, a small part of the light flux from the end of the lamp goes to lighting. The temperature of the heater body, depending on the ambient temperature, ranges from 70 to 100 ° C.

The amount of heat generated exceeds the heat generated by a 500 W spiral type heater.

A diffuser is mounted on the housing 1 as a cover 7. In contrast to the considered device according to Example 2, the heater additionally contains a fan located below the housing 1. An insignificant part of the light flux from the end of the lamp goes to the lighting. Case temperature depends on fan performance. The difference in air temperature at the inlet and outlet is 30-40 ° C.

The amount of heat generated exceeds the heat generated by a 700 W spiral type heater.
