Description

[0001] Field of technology to which the utility model belongs

[0002] The utility model relates to heating systems, namely to a convector body, which is installed under the floor of a heated room so that the upper part of the convector is flush with the upper surface of the floor.

[0003] Technology Level

[0004] The prior art discloses a floor convector comprising a housing made in the form of an elongated rectangular parallelepiped with open ends, in which a fan and at least one radiator extending along one longitudinal side are optionally located (see DE 202009016714 U1, published 15.04.2010).

[0005] From document RU 173667 U1, publ. 09 / 05 / 2017, a floor heating convector is known, comprising a frame with supports connected to each other, a heat exchanger fixed to the frame brackets, the branches of the pipe of which are connected through the corner pipes of the heat exchanger connection unit with the pipes of the heating system, as well as a casing including an air outlet grille, front, rear and side walls, characterized in that the frame is made in the form of a rectangular spatial structure from longitudinal and transverse elements connected to each other, each part of the casing is made rectilinear and connected to the frame, the grille is formed by transverse and longitudinal rods, the longitudinal rods of the grille freely rest on top of the transverse elements of the frame, on each longitudinal side of the front and rear walls of the casing an L-shaped flanging is made in which a longitudinal element of the frame is located with the possibility of longitudinal movement, the side walls of the casing are detachably connected to the frame,the front and rear walls of the casing, the supports are located in the plane of the brackets with their displacement to one of the sides of the convector so that on the opposite side of the convector in the casing a space is formed in which the connection unit of the heat exchanger with the pipes of the heating system is located.

[0006] The closest analogue was chosen to be an in-floor convector, information about which is posted on the website https: / / splpro.ru / spl-instyle-nc / .

[0007] The specified floor convector contains a box made of galvanized steel, the side and end walls are connected with screws.

[0008] The disadvantages of known analogues are that the body is made of galvanized steel and the box parts are connected using screws.

[0009] Disclosure of the essence of the utility model

[0010] The above mentioned disadvantages are eliminated in the utility model by making the housing from a polymer material, the elements of the housing are connected to each other using a tongue and groove type.

[0011] Floor temperature fluctuations can cause deformation of the casing of the underfloor heating convector, which can affect the overall operation of the convector.

[0012] The technical result is resistance to temperature changes, due to the minimization of deformation of the casing of the underfloor heating convector during temperature fluctuations, by making the casing elements from a polymer material, connected to each other using the tongue and groove type.

[0013] The technical result is achieved by the body of the underfloor heating convector, which contains two side walls, two end walls, as well as a base and heat exchanger supports, made of a polymer material, connected into a single structure using a tongue and groove type.

[0014] When operating an in-floor heating convector, it is the polymer housing elements that minimize deformations due to the fact that the polymer material has low thermal conductivity, and the tongue-and-groove connection of the housing parts provides additional reinforcement to minimize deformation due to a strong connection.

[0029] Implementation of a utility model

[0030] The polymer convector body is a part of the floor convector, it is a body (casing, box, bath), in which a copper-aluminum heat exchanger is located.

[0031] The polymer body of the convector consists of side walls 1, end walls 2, base 3, connected to each other using a tongue and groove 4 (profile connection).

[0032] Heat exchanger supports 5 are additionally installed inside the assembled housing, which provide additional rigidity to the housing and end walls 2. The side 1 and end 2 walls are fastened together using internal plates 5 and the base 3 using a tongue-and-groove connection.

[0033] The tongue and groove joint consists of a T-shaped tongue 6 and a corresponding T-shaped groove 7.

[0034] T-shaped grooves 7 are made on the upper and lower parts of the side 2 walls. In this case, the side walls 2 of the housing contain stiffening ribs at the location of the grooves 7.

[0035] The heat exchanger supports 5, the base 3 and the end walls 2 contain T-shaped pins 6 that match the grooves.

[0036] U-grooves 8 are made on the inner plates 5 for placing heat exchanger tubes in them.

[0037] The tongue and groove connection is characterized by high strength, which ensures minimal deformation of the housing when it is installed in a concrete floor, due to temperature changes, in which the concrete floor either expands when heated or contracts when cooled.

[0038] The body elements are made of polymeric material (polypropylene, polyvinyl chloride, or polyethylene) which provides lower thermal conductivity, which results in a reduction in heat loss in the heating device.

[0039] The polymer side walls 1 and the base 3 of the housing are manufactured using a spinneret-type extrusion method (a continuous process of squeezing the melt through a mold to create long products) of polymer raw materials, the end walls 2 and inner plates 5 of the housing are manufactured using an injection molding method to give the required shape.

[0040] Thus, the utility model ensures the achievement of a technical result consisting in minimizing the deformation of the body of the in-floor heating convector.
