Description

[0001] HEAT-COOLING PROFILE WITH LED LIGHT SOURCES

[0002] Field of technology

[0003] The utility model relates to the field of heating technology, in particular to radiant heating systems and ceiling cooling systems, with a lighting function, more specifically, the claimed utility model relates to a heat-cooling profile with a lighting function, and can be used to maintain a specified temperature regime in residential and industrial premises in winter and summer, and to illuminate said premises. One of the most basic areas of application of the utility model is in greenhouses for uniform heating and lighting of agricultural crops in closed spaces.

[0004] State of the art

[0005] Radiant heating systems are widely known in the state of the art. Radiant heating is a type of heating in which heat is transferred to the heated room mainly by radiation and, in a much smaller amount, by convection. Heating panels are used for radiant heating - heating devices with a continuous smooth heating surface. The flow of thermal radiation from the heating panels, absorbed by the surfaces of enclosing structures and objects, as well as clothing and human skin, creates thermal comfort without increasing the ambient air temperature, so the air temperature can be lower than in rooms with other types of heating, which is an advantage of radiant heating. The air in heated rooms is heated by convection from structures and objects heated by radiation. Radiant heating is most effective for rooms with high ceilings.

[0006] Radiant heating systems can be central or local. In a local system, the heat carriers in medium- and high-temperature heating devices are electric current or combustion products of flammable gas or solid fuel. In a central radiant heating system, low- and medium-temperature panels with centralized heat supply using heated water and air, less often high- and low-pressure steam are used. Heating devices in radiant heating are placed under the ceiling, in the floor or in the walls. When placing heating devices under the ceiling, the flat surface that gives off heat is called a heating panel. Heating systems with such devices are called panel-radiant. There are radiant heating systems in which the ceiling, which transfers heat to the room, is heated by hot air supplied under the ceiling, into the room.Radiant heating systems with heating panels can be used in summer to cool rooms, for which cold water is passed through the pipes where the coolant passed in winter. In this case, it is necessary that the temperature of the cooling surface coming out into the room (to prevent moisture condensation on it) is higher than the dew point temperature of the air in the room.

[0007] Also known in the state of the art are Russian ceiling water heating panels "Teplopanel" - radiating infrared heating devices, see the Internet link: https: / / rus-radiator.ru / catalog / potolochnye-paneli-teplopanel. They are used when it is necessary to heat rooms with high ceilings and large volumes, such as industrial production facilities of enterprises, workshops, hangars, warehouses, garages and auto service boxes, passenger terminals, railway stations, shopping centers, car dealerships, exhibition complexes, conference halls, sports facilities, indoor tennis courts, depots, docks, etc.

[0008] The operation of the Russian-made Teplopanel radiant heating panels is based on the transfer of heat (infrared radiation) from them - directly to objects in the room and enclosing structures (walls, floor, glass). The air from them is heated as if a second time, and more evenly over the entire height. The classic problem of heating, carried out by the convective method, when the heated air rises upward and the warmest air accumulates under the ceiling, and it is uncomfortably cool near the floor, is significantly smoothed out. With a large area of ​​glazed walls, due to the heating of the glass from the inside, condensation and frost do not form.

[0009] The source of hot water can be both traditional suppliers - boiler houses, central heating stations, heating utility networks, etc., and alternative heat generation - heat pumps, solar systems. It should be noted that when cold water is supplied to the panel pipes, it will work to cool the room.

[0010] The surface of the panel visible from below is smooth and solid, but it is also possible to use perforated sheets for production, as well as the possibility of making technological openings for lighting, ventilation, and fire alarm systems.

[0011] Known ceiling infrared heating systems and devices are made of steel or stainless steel structures with mechanical connections, are complex, which increases the time of heating in the cold season and cooling in the warm season of the premises to a given temperature and reduces the efficiency of transfer, respectively, of heat and cold. In addition, most of the known radiant heating systems / devices in the prior art do not have a built-in lighting function, and in those designs in which it may be present, there is no system for installing LEDs with preservation of their service life. Thus, there is a problem of heating the installed light sources, for example, in a radiant heating panel, due to the implementation of technological holes for lighting systems directly near the radiating surface. The location of the light sources in the radiating surface zone will lead to their overheating and failure.

[0012] Disclosure of the essence of the utility model

[0013] The objective of the utility model is to create a heat-cooling profile that is capable of not only effectively cooling and heating rooms, but also illuminating them.

[0014] The technical result of the claimed utility model consists in eliminating the shortcomings of the nearest level of technology and developing a design of a heat-cooling profile with a lighting function, in which LED light sources have a long service life.

[0015] The technical result is achieved due to the design of a heat-cooling profile with LED light sources, which is a housing, inside which a pipe for the coolant is located, and containing LED light sources placed on a substrate, which is located on the lower surface of the housing with the lowest temperature and on the opposite side from the pipe for the coolant.

[0016] In an embodiment of the utility model, the heat-cooling profile is ceiling-mounted and the LED light sources are covered by a diffuser.

[0017] Brief description of the drawings

[0018] Fig. 1 shows a general view of a heat-cooling profile with LED light sources.

[0019] Implementation of a utility model

[0020] The utility model is a heat-conducting element, for example, a housing made of aluminum, coupled by heat flow with a source of thermal energy and / or cold, with a built-in and integral heat-emitting / heat-receiving pipeline.

[0021] Higher heating efficiency, compared to solutions known in the state of the art, is achieved by implementing a monolithic heat-cooling profile design, in which the housing with the coolant pipe located inside the housing are a single unit, as well as due to the housing material. The housing is made of a material with high thermal conductivity, namely, aluminum. Due to the aluminum housing, the flow of the coolant, such as hot water, through the coolant pipe channel is realized without heat loss.

[0022] In accordance with Fig. 1, which shows a general view of the heat-cooling profile with LED light sources, the claimed utility model is an aluminum housing 1, inside which a pipe 2 for a coolant is located. Water, hot or cold, can be used as a coolant, depending on the season. Thus, in the cold season, the hybrid heat-cooling profile implements the function of heating the premises to a specified temperature, and in the warm season - the function of cooling. The housing 1 with the pipe 2 for the coolant are made as a single unit, without jumpers and additional parts, due to which heat / cold is distributed evenly throughout the profile and effectively transfers it to the environment. The heat-cooling profile contains LED light sources 4, placed on a substrate 3, which is located on the lower surface of the housing 1 and on the opposite side from the pipe 2 for the coolant, as shown in Fig. 1.The substrate 3 is used to remove the generated heat and serves as a radiator for the LED light sources. The LED light sources 4 are covered by a diffuser 5, which protects them from external influences. Due to the presence of the LED light sources 4, the heat-cooling profile acquires a new function and is used for lighting rooms.

[0023] From general knowledge about the efficient operation of LED light sources, it is known that the main problem of LED failure is their overheating. To avoid overheating, it is necessary to take care of their additional cooling. Due to the placement of the heating pipeline 2 on top, and the LED light sources 4 on the lower surface of the housing 1, made of aluminum, heat reaches the LEDs 4 with preliminary cooling, due to which the LEDs 4 do not overheat and their service life increases. In addition, due to the spacing of the pipe 2 for the coolant and the substrate 3 with the LED light sources 4 on opposite sides of the housing 1, their location on the upper and lower surfaces of the housing 1, respectively, the LED light sources 4 will be at a sufficient distance from the pipe 2 with the coolant in order to heat up less and cool well. This ensures a long service life of the LED light sources 4.
