Description

Technical field

The utility model relates to the field of heating technology, in particular to radiant heating systems and a ceiling cooling system, 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 given temperature regime in residential and industrial premises in winter and summer, and lighting of these premises. One of the most basic areas of application of the utility model is in greenhouses for uniform heating and lighting of crops in confined spaces.

State of the art

Radiant heating systems are widely known in the art. Radiant heating is a type of heating in which heat is transferred into the heated room primarily by radiation and in a much smaller amount by convection. For radiant heating, heating panels are used - heating devices with a continuous smooth heating surface. The flow of thermal radiation from heating panels, absorbed by the surfaces of enclosing structures and objects, as well as human clothing and skin, creates thermal comfort without increasing the ambient 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 ceiling heights.

Radiant heating systems can be central or local. With a local system, the coolants 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 are used with centralized heat supply using heated water and air, and less often high- and low-pressure steam.

Heating devices for radiant heating are placed under the ceiling, in the floor or in the walls. When heating devices are placed under the ceiling, the flat, heat-transmitting surface is called a heating panel. Heating systems with such devices are called panel radiant. There are radiant heating systems in which the heating of the ceiling, which transfers heat into the room, is carried out by hot air supplied under the ceiling into the room. Radiant heating systems with heating panels can be used in the 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 entering the room (to prevent moisture condensation on it) is higher than the dew point temperature of the air in the room.

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

The operation of radiant heating panels “Teplopanel”, produced in Russia, is based on the transfer of heat (infrared radiation) from them directly to objects in the room and its enclosing structures (walls, floors, glass). The air from them is heated, as it were, a second time, and more evenly over the entire height. The classic heating problem, carried out by convection, is significantly smoothed out, when heated air rises and the warmest air accumulates under the ceiling, and it is uncomfortably cool near the floor. If there is a large area of glazed walls, due to the heating of the glass from the inside, condensation and frost do not form.

The source of hot water can be either traditional suppliers - boiler houses, central heating stations, thermal utility networks, etc., or alternative heat generation - heat pumps, solar systems.

It should be noted that when cold water is supplied to the pipes of the panel, it will work to cool the room.

The surface of the panel visible from below is smooth and solid, but there is also the possibility of using it for the production of perforated sheets, as well as the possibility of making technological holes for lighting, ventilation, and fire alarm systems.

Known systems and devices for ceiling infrared heating are made of steel or stainless steel structures with mechanical connections and are complex, which increases the time of heating in the cold season and cooling in the warm season of rooms to a given temperature and reduces the efficiency of transfer of heat and cold, respectively. In addition, most radiant heating systems/appliances known in the art do not have a built-in lighting function, and those designs that may have it do not provide a system for installing LEDs to preserve their service life. Thus, there is a problem of heating installed light sources, for example, in a radiant heating panel, due to the execution of technological holes for lighting systems directly near the radiating surface. The location of lighting sources in the area of the emitting surface will lead to their overheating and failure.

Disclosure of the essence of the utility model

The purpose 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.

The technical result of the claimed utility model consists in eliminating the shortcomings of the current state of the art and developing a design of a heat-cooling profile with a lighting function, in which LED light sources have a long service life.

The technical result is achieved due to the design of a heat-cooling profile with LED light sources, which is a housing, inside of which there is a pipe for the coolant, 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 coolant.

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

Brief description of drawings

Figure 1 shows a general view of a heat-cooling profile with LED light sources.

Implementation of a utility model

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

Higher heating efficiency, compared to solutions known in the prior art, is achieved due to the monolithic design of the heat-cooling profile, in which the housing and the coolant pipe located inside the housing are a single whole, as well as due to the material of the housing. The housing is made of a material with high thermal conductivity, namely aluminum. Thanks to the body being made of aluminum, the flow of coolant, such as hot water, through the channel of the coolant pipe is realized without heat loss.

According to FIG. 1, which shows a general view of a heat-cooling profile with LED light sources, the claimed utility model is an aluminum housing 1, inside of which there is a pipe 2 for the coolant. Water, hot or cold, can be used as a coolant, depending on the time of year. Thus, in the cold season, the hybrid heat-cooling profile implements the function of heating the premises to a given temperature, and in the warm season - the cooling function. Housing 1 with coolant pipe 2 is made in one piece, without jumpers or additional parts, due to which heat/cold is distributed evenly throughout the entire 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 of the coolant pipe 2, as shown in Fig.1. Substrate 3 is used to remove generated heat and serves as a heat sink for LED light sources. LED light sources 4 are covered with a diffuser 5, which protects them from external influences. Thanks to the presence of 4 LED light sources, the heat-cooling profile acquires a new function and is used for indoor lighting.

From general knowledge about the efficient operation of LED light sources, it is known that the main problem with 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 pipe 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 pre-cooling, due to which the LEDs 4 do not overheat and their service life increases. In addition, due to the separation of the pipe 2 for the coolant and the substrate 3 with 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 to heat up less and cool well. This ensures a long service life of LED light sources 4.
