Description

Description of the invention

The invention concerns a heat pipe wall heating module, particularly for residential buildings, hotels, schools, and office spaces. Heat pipe wall heating not only allows for more cost-effective heating of buildings than existing methods, but also ensures high thermal comfort and lower operating costs.

Heat transfer uses a working medium present in two states of matter: a liquid boiling at 35-55°C and vapor condensing and transferring heat. The boiling and condensing processes occur within the heat pipe. Conventional heat pipes are constructed of stainless steel and connected to a supply manifold made of copper pipe, forming a panel. Panels constructed in this way can be combined into packages.

A heat pipe module is known from the utility model application W.110482, which is an external pipe equipped with an internal working medium collector, and the space between the external wall of the collector and the internal wall of the pipe is closed with reducing joints and is connected to one heating loop, which is placed outside the external pipe.

The disadvantage of this solution is the loudness of the sounds emitted during intense heating caused by the flow of boiling liquid in the heat pipe.

Also known from the invention description PL 385840 is a heat pipe module for heat transfer for heating purposes, which has an outer tube equipped with an internal working medium collector and heating loops connected through the outer tube to the space between its inner surface and the outer surface of the collector. According to the invention, the solution is characterized by a spiral recess formed on the collector wall.

The spiral recess in the collector wall allowed for the elimination of the negative phenomenon of rapid bubble boiling of the liquid in the heat pipe, but the applied design solution causes problems related to the tightness of the entire system, which is extremely important due to the location of these elements in the wall.

The Polish patent application P.405037 describes a wall heating panel consisting of an aluminum collector made of a multi-channel aluminum profile with one parallel horizontal phase change channel plugged at both ends and a horizontal water channel terminated with connectors on both sides.

The invention is a first module for a hot-water wall heating system, which comprises a collector and a heating loop containing a heating medium. The collector, equipped with a horizontal water channel, comprises a metal layer containing a horizontal tube-shaped element through which hot water flows. Adjacent to the horizontal tube-shaped element is a heating loop, preferably consisting of two identical U-shaped parts, with the corresponding arms of each part connected at the top after assembly, i.e., the left arm is connected to the left arm, and the right arm is connected to the right arm. Preferably, the lower part of each heating element is bent outward so that its inner surface abuts the horizontal tube-shaped element. The horizontal tube-shaped element, the lower part of the heating loop, and partially its arms are also surrounded by a metal layer, preferably tin. Preferably, both the horizontal tube-shaped element through which hot water flows and the heating loop are flattened. The metal layer stabilizes both elements and is also the material that transfers heat from the horizontal tube-shaped element to the heating loop.

The second wall heating module consists of a water collector and a heating loop containing a heating medium. The water collector is constructed of two permanently connected identical parts, preferably rectangular in plan. Each collector part has identical longitudinal recesses in its longitudinal axis, i.e., two outer recesses and one central recess. Preferably, the outer recesses and the central recess are half-cylindrical, and preferably the radius and length of the central recess are greater than the radius and length of the outer recesses. Additionally, each of the two identical collector parts has recesses perpendicular to the outer recesses and the central recess located in the longitudinal axis, in which the vertical arms of the heating loop are located. Preferably, the perpendicular recess in both collector parts is half-cylindrical. Preferably, one of the collector parts has openings along the upper edge, and embossed projections along the lower edge. Preferably, the second part of the collector has identical openings and projections, with the projections along the upper edge and the openings along the lower edge. Both parts of the collector are connected so that the projections are located within the openings, creating a permanent connection. The connection of the two parts of the collector creates a central chamber shaped by a central recess, which houses the lower part of the heating loop and the heating medium, and two outer chambers formed by the outer recesses. The outer chambers form an inlet and outlet through which the heating medium flows. Additionally, the collector and the heating loop within it are surrounded by a layer that seals the connection between the collector and the heating loop. Preferably, this layer is a layer of tin or an adhesive.

The solutions used are characterized by a simple design, which at the same time ensures a high level of tightness of the entire heat pipe module.

The subject of the invention is shown in an example embodiment in the drawing, in which Fig. 1 shows the heating module in a longitudinal cross-section in the first version of the embodiment, Fig. 2 - in a cross-section in the first version of the embodiment, Fig. 3 - in a longitudinal cross-section in the second version of the embodiment.

Example 1.

The invention concerns a first hot-pipe wall heating module, which consists of a collector and a heating loop 1 containing a heating medium, wherein the collector is a metal layer 3 in which a horizontal tube-shaped element 2 through which hot water flows is located. Adjacent to the horizontal tube-shaped element 2 is a heating loop 1 comprising two identical parts in a form similar to the letter U, wherein the corresponding arms 13 of each part, after being assembled, are connected to each other at the top, i.e., the left arm to the left, and the right arm to the right. The lower part 12 of each heating element part is bent outward so that its inner surface abuts the horizontal tube-shaped element 2. The horizontal tube-shaped element 2 and the lower part 12 of the heating loop 1, and partially its arms 13, are also surrounded by a metal layer 3, preferably tin, and both the horizontal tube-shaped element 2 through which hot water flows and the heating loop 1 are flattened. The metal layer 3 in liquid form, when solidifying, stabilizes both elements, i.e. the heating loop 1 and the element in the shape of a horizontal pipe 2, and is at the same time a material transferring heat from the element in the shape of a horizontal pipe 2 to the heating loop 1, heating the heating medium.

Example 2.

The second module of the heat pipe wall heating consists of a water collector 10 and a heating loop 9 containing a heating medium, wherein the water collector 10 consists of two identical parts made of steel, built on a rectangular plan. Each part of the collector 10 has identical longitudinal recesses in its longitudinal axis, i.e. two outer recesses 11 and one central recess 4. The extruded recesses have the shape of a half cylinder, and the radius of the central recess 4 and its length are greater than the radius and length of the outer recesses 11. Additionally, each of the two identical parts of the collector 10 has recesses 5 perpendicular to the outer recesses 11 and the central recess 4 placed in the longitudinal axis, in which the vertical arms of the heating loop 9 are located. The connection of both parts of the collector 10 forms a central chamber shaped by the central recess 4, in which the lower part of the heating loop 9 is placed and in which the heating medium is located, and the outer chambers formed by the outer recesses 11, which are the entrance and exit, through which water flows, i.e. the medium heating the heating medium in the heating loop 9. In one of the parts of the collector 10, along the upper edge line, are holes 6, and along the lower edge line, are embossed projections 7. The second part of the collector has identical holes 6 and projections 7, wherein in this part, projections 7 are located along the upper edge line, and holes 6 along the lower edge line. Both parts of the collector 10 are connected so that projections 7 fit in holes 6, creating a riveted connection. Additionally, the collector 10, with the heating loop 9 located therein, is surrounded by a layer 8, which seals the connection between the collector 10 and the heating loop 9. This layer 8 is a layer of tin or an adhesive layer.
