(54) СТЕНОВАЯ ПАНЕЛБ(54) WALL PANELB

II

Изобретение относитс к области строительства , а именно, к стеновым панел м с теплонагревательными приборами.The invention relates to the field of construction, namely, to a wall panel with heat heating devices.

Известны стеновые панели, в которых две бетонные плиты скреплены между собой с помощью ребер, а пространство между плитами заполнено тепловой изол цией причем в плите, располагаемой со стороны отапливаемого помещени , размещен змеевик из труб дл подачи теплоносител 1.Wall panels are known, in which two concrete slabs are fastened together by means of ribs, and the space between the plates is filled with thermal insulation, and in the plate located at the side of the heated room a coil of pipes for supplying heat carrier 1 is placed.

В этих панел х плита со змеевиком вплотную примыкает к слою тепловой изол ции, что приводит к дополнительным потер м теплоты наружу здани , к. тому же дл полезной теплоотдачи в помещение используетс только одна сторона змеевика, что вызывает увеличение его длины.In these panels, a stove with a coil closely adjoins the thermal insulation layer, which leads to additional heat loss outside the building, in addition, only one side of the coil is used for useful heat transfer to the room, which causes an increase in its length.

Известна также отопительна панель/ имеюща две скрепленные между собой с помощью ребер жесткие плиты и расположенный между плитами слой теплоизол ции, а между слоем тепловой изол ции и плитой, примыкающей к отапливаемому помещению имеетс воздушный зазор, в котором размещен змеевик из труб, причем воздух в зазоре имеет свободный вход и выход в помеЩение через щелевидные отверсти в верхней и нижней част х плиты, расположенной р дом со змеевиком 2.Also known is a heating panel / rigid plates, which are fastened together with ribs and have a thermal insulation layer between the plates, and there is an air gap between the thermal insulation layer and the stove adjacent to the heated room, in which a coil of pipes is placed, The gap has free entry and exit to the room through slit-like openings in the upper and lower parts of the slab located adjacent to the coil 2.

Недостатком известной отопи/ельной панели вл етс низка теплоотдача нагревател в сторону воздущного зазора, что объ сн етс поглощением поверхностью тепловой изол ции, теплового излучени нагревател , которое передаетс затем наружу здани .A disadvantage of the known heating panel is the low heat emission of the heater towards the air gap, which is explained by the absorption of thermal insulation of the heater by the surface, which is then transmitted outside the building.

Наиболее близкой к изобретению по технической сущности и достигаемому резульхату вл етс комплексна стенова панель, имеюща две соединенные между собой ребрами наружную и внутреннюю бетонные плиты , со-слоем тепловой изол ции между ни- , ми, прилегающим к наружной плите и змеевиком нагревател во внутренней плите, расположенной с воздущным зазором относительно тепловой изол ции, сообщающимс с помощью щелевидных отверстий с воздухом помещени . Дл уменьщени теплопотерь наружу здани змеевик размещен вClosest to the invention of the technical nature and the result achieved is a complex wall panel having two interconnecting outer and inner concrete slabs with ribs, a thermal insulation layer between the wires adjacent to the outer plate and the heater coil in the inner plate located with an air gap relative to thermal insulation, communicating through the slit-like openings with the air of the room. To reduce heat loss outside the building, a coil is placed in

плите, примыкающей к отапливаемому помещению 3.stove, adjacent to the heated room 3.

Claims

In this panel, the heat radiation of the heater towards the air gap is absorbed by the thermal insulation surface. and then transferred to the outside of the building, resulting in a decrease in the heat output of the panel in the heated room. The aim of the invention is to increase the heat transfer of the panel. This goal is achieved by the fact that in a known integrated panel containing outer and inner concrete slabs rigidly interconnected with ribs with a thermal insulation layer between them adjacent to the outer slab and a heater coil in the inner slab located with an air gap relative to thermal insula tion having exits to the enclosed space, a screen is installed in the air gap, the surface of which is heat-absorbing on the heater side, and heat-reflecting on the back side; ovany horizontal slots disposed in the space between the tubes of the coil. In addition, the screen in the middle part has a flat surface, and in the upper and lower parts it is bent along the air flow along the curve defined by the ratio r / d Go / d + 0.6, where r is the curve radius; d is the thickness of the air gap; . Go is the radius of rounding of the edges of the inner plate facing the air gap. The drawing shows a wall panel with a partial cut, general view. The wall panel has ribs 1 and 2 bonded to each other, concrete plates 3 and 4, between which thermal insulation layer 5 is located. There is an air gap between the plate 4 in which the coil 6 is placed and the thermal insulation layer 5 - a flat air cavity 7 okhvatyvayuschy zone of placement of the coil 6 and communicating with the air of the room through the slit-like holes 8 and 9 in the plate 4. The air gap 7 contains a screen 10 with slots 11 located in the space between the pipes of the coil 6. In its middle part the screen 10 has a flat surface and in the upper and lower parts they are bent along the air flow along the curve determined by the ratio r / d T0 / d + 0.6. The surface of the screen from the side of the heater is heat-absorbing, and from the back - heat-reflecting. The heat transfer process in the panels from the coil to the indoor air is as follows. From the heated part of the plate 4, going out into the room, heat is transferred by means of convection and radiation, from the surface of the plate 4, going out into the channel, only by convection, the room air entering the gap 7 through the hole 8, and heating, goes into the room through the hole 9. To use the thermal radiation of the surface of the plate 4 exiting the channel, the heat-absorbing surface of the screen 10 serves, from which heat is transferred to the room air by convection. To intensify convection heat exchange, the heat absorbing surface of the screen 10 with air moving in the gap 7 serves horizontal slots 11. The hydrodynamic boundary layer, dislodging from the slits of the slots, vibrates the air moving along the screen 10 and thereby intensifies heat exchange. To reduce the hydraulic resistance, the screen is located along the current line of the air moving in the gap 7, while the gap 7 does not form stagnant zones in the form of closed vortex flows, which also increases the heat transfer of the panel.

Wall panel comprising interconnecting outer and inner plates with ribs with a thermal insulation layer between them adjacent to the outer plate and a heater coil in the inner plate located with an air gap relative to thermal insulation. having exits to the enclosed space, characterized in that, in order to increase heat transfer, a screen is installed in the air gap, the surface of which is heat-absorbing on the heater side and heat-reflecting on the back side, with horizontal slots in the screen located in the space between the coil pipes . 2.
