It relates to a heat exchanger that has at least one lid to which it is connected. 10 PREVIOUS TECHNIQUE Combination boilers are commonly used for heating homes and preparing domestic hot water. These are gas-fired heating devices used as condensing boilers. In condensing boilers, 15% of the combustion products... By condensing the water vapor, the latent heat is also recovered. These types of devices... Typically, a fan-assisted burner, which transfers the heat of the flue gases heated by this burner to the usage / installation. It includes a heat exchanger that transfers heat to the water and suitable flue gas extraction systems. In these devices, the heat exchanger connects the hot flow on the gas side with the flow on the water side. It provides heat transfer between them and ensures that the gas circuit and the water circuit are leak-proof. The aim is to separate the hot gases exiting the burner across the heat exchanger surfaces. The water is directed on / around the heat exchanger, absorbing heat as it passes through the water path. During this process, keeping gas and water circuits separate is a well-known principle in engineering. In current technical heat exchangers, the distribution of gas flow over the tube bundle is always the same. It may not be homogeneous, heat transfer towards the shell may increase, and therefore the shell Unwanted heating and heat losses can occur in the components. This situation affects the flow. Due to the irregular spread of heat as it hits the body, it leads to a decrease in heat transfer efficiency. It can open. 30 Additionally, there are difficulties regarding gas tightness between the burner and the heat exchanger cover. This can happen. Existing burner and cover connections allow gas to leak into the environment. This causes problems. Another leak point is where the water enters the pipe. This is happening. In current practices, the pipe connecting the water circuit to the heat exchanger is 35 Sealing problems due to the risk of slippage at the ends during assembly and use. 2 This can occur. In other words, gas leakage can occur between the shell and the pipe. It is possible to come. In the area in question, in other words between the body and the pipe, plastic ends are used in some manufacturing processes. A connection is made at the interface of metal and plastic using a form, in such arrangements 5 Risk of water coming into contact / mixing with gas due to movement of the pipe end. It can increase. Insulation elements of the base plate (for example, sheet metal parts) which are components of the body In its detection, it is important to maintain the perpendicularity tolerance of the top connections made with spot-welded bolts. if it is insufficient and the connection breaks, the insulation material flows into the interior space. It is also known that this can lead to undesirable consequences such as increased flow. This situation affects both the flow. This can disrupt the system and negatively affect efficiency due to heat leaks. In conclusion, all the problems mentioned above necessitate an innovation in the relevant technical field. It has made it mandatory.

Another aim of the invention is to create a product with a completely metal end-form and a special shape. a heat exchanger that prevents water from mixing with the gas circuit through a leak-proof fitting to reveal. 35 3 Another purpose of the invention is to create a double stopper (first wall, second wall) on the shell and tube. This prevents the pipe from slipping back during assembly and use, ensuring a permanent leak-proof seal. The goal is to create a heat exchanger. Another purpose of the invention is to prevent gas leakage between the protrusion on the body and the pipe outlet. 5 The goal is to create a heat exchanger that prevents leakage. All the purposes mentioned above and those that will emerge from the detailed explanation below.

By providing support, the gasket is prevented from moving out of place. 4 A characteristic feature of a possible design of the invention is that the inlet opening is directed towards the aforementioned protrusion. It must include at least a second wall extending beyond the first. Thus, the sealing part is double-sided. By compressing the material, a long-lasting leak-proof seal is achieved. A characteristic feature of a possible design of the invention is that it is surrounded by a protrusion and an inlet opening, 5 It must contain at least one watertight piece located between the first and second walls.

A characteristic feature of a possible design of the invention is that the canal cross-section is arc-shaped. A feature of a possible design of the invention is that the sealing part faces the protrusion. It must contain at least one crack on its surface. This allows the sealing part to adhere better to the body.

It is explained with examples that do not create any limiting effect on understanding. Figure 1 shows an isometric view of the heat exchanger (1) that is the subject of the invention. Heat exchanger 5 (1) is used in heating devices, especially water heaters. In the preferred configuration The heating device is a condensing boiler. The heat exchanger (1) is the heat produced by the combustion of a gas (G). It enables the heating of water using heat. The heat exchanger (1) contains at least one cover (40). The said cover (40) is in the form of a ring of 10 It is connected to at least one burner (50) placed in the hole. The burner (50) is a gas the combustion of the gas (G) entering the interior environment (I) from the inlet (GI) inside the heat exchanger (1). By inner environment (I) means the inside of the heat exchanger (1), i.e., where combustion takes place. This is the section. Combustion produces burnt gas. The burnt gas passes through the heat exchanger. (1) To prevent leakage into the outside environment (O), at least one groove (40) in the lid 15 There is at least one sealing element (60) located in (41). The groove (41) is shown in Figure 4 and As can be seen in 7, the cover (40) is a circular channel on its surface. Another In other words, the lid (40) is the part between the two peaks (42) that extend outwards from the top surface. The sealing element (60) is placed in this groove (41) and as shown in Figure 7. It is located between the burner (50) and the cover (40). In this way, the cover (40)-burner (50) 20 The hot gases resulting from combustion from the connection exceed the said peak (42) obstructed and as a result the exhaust gases easily leave the shell (10) and outside The escape of heat to the environment (O) has been prevented. In addition, heat loss in the pipe (30) has also been prevented. It has been reduced. Therefore, the channel (41) is not embedded in the surface of the cover (40), but between the two peaks (42) It is a structure formed by extending from the surface of the lid (40) towards the burner (50). 25 The heat exchanger (1) contains at least one shell (10). The aforementioned shell (10) encloses the housing. It is in a hollow cylindrical form. The body (10) has at least one, as can be seen in Figure 2. It consists of a first part (11) and at least one second part (12). In other words, The first part (11) and the second part (12), which are in the form of a semi-cylindrical shell, are joined to form a cylindrical 30 It forms the body (10). The first part (11) and the second part (12) are connected to each other. It contains at least one connection lane (14) to enable their connection. When the strips (14) are positioned on opposite parts, they can interlock with each other is configured. In other words, the first part (11) and the second part (12) are cylindrical. 35 by means of connecting strips (14) to each other to form the body (10). It is connected. The connecting strip (14) is connected along the first part (11) and the second part (12). It is a structure with multiple T-shaped extensions. In this way, the first part (11) and the second part 7 (12) they can be guided to each other and alignment can be achieved. Then, connecting strips (14) to each other at multiple points of mechanical compression heat exchanger (1) The risk of leakage throughout the service life has been minimized. The heat exchanger (1) contains at least one pipe (30). Pipe (30) carries the water entering from the inlet (31), 5 This allows the water to be advanced to the outlet (32). Meanwhile, the water is drawn inside by means of the burner (50). The environment (I) is heated by burning the gas (G). The pipe (30) is cylindrical in shape, a In other words, it extends vertically in a spiral shape. In this way, the entrance (31) enters As the water moves upwards in a controlled, circular motion, it heats up and exits. It comes out of the mouth (32) as hot water. The inlet mouth (31) is metal. Pipe (30), 10 It contains a curved form (33) on one side of its rectangular cross-section. In other words, the existing Unlike rectangular cross-section pipes in the technique, one edge is, in the preferred configuration The shorter side is an arc with a specific radius, resulting in the vertical line shown in Figure 11. It is asymmetrical on the axis. The curved form in question (33) is directed to the interior environment (I), that is, to the combustion It is on the edge facing the center where it occurs. The other edge is straight. 15 In this way, an increase in thermal efficiency and condensation efficiency has been achieved. This is made possible by the combustion. It is the extension of the straight section as the natural gas passes between two pipes (30). Therefore, a rectangular section pipe (30) with curved form (33) and a straight edge, both sides rounded It has a larger heat transfer surface area depending on the profile shape. All helical tube (30) 20 Because this effect continues throughout, it has a positive impact on product efficiency. The heat exchanger (1) contains at least one separator (20). The separator (20) is connected to the tube (30) and shell (10) It is located between them. The separator (20) is made up of two different parts, like the body (10). Therefore, at least one first separator (21) and at least one second separator (22) 25 There are also semi-cylindrical shells in the first separator (21) and the second separator (22). It is in this form. The separator (20) directs the burnt gas coming out from between the spiral pipe (30) into the shell (10) It acts as a heat shield to reduce heat transfer. To achieve this, 30 There is a distance between the body (10) and the separator (20). In other words, the distance between the body (10) and a distance between the fuselage (10) and the heat shield will be created such that an air gap is formed between them. It is positioned in such a way as to create heat insulation. Thus, the body (10) By reducing the transmitted heat, the thermal effect remains inside the heat exchanger (1) and the pipe (30) is efficient The aim was to heat it. Thus, an increase in efficiency was achieved due to the thermal gain. 35 8 In the current technique, the end-forming is done at the point where the inlet (31) of the pipe (30) and the shell (10) meet. (also known as its structure) gas leaks and water-gas mixtures occur. This In order to prevent this, the heat exchanger (1), in the shell (10), at least a part of the inlet port (31) It includes at least one protrusion (13) surrounding it. In other words, the protrusion (13) is cylindrical. It is another cylinder that surrounds the inlet opening (31) and extends outwards from the body (10). 5 The projection (13) has at least one first wall (131) extending towards the entrance (31) inside it. It contains. The first wall (131) has a cylindrical projection (13) that makes a full turn around the inner surface. It is a structure. Preferably at the end of the projection (13). It functions together with the first wall (131). The entrance opening (31) also has at least one second wall (311) extending from its outer surface to the projection (13) It includes. The second wall (311) also has 10 walls around the entire circumference of the cylindrical inlet opening (31). Therefore, the first wall (131) extending from the projection (13) and the entrance mouth (31) A nest (101) has been formed between the second wall (311) that extends. To the nest in question At least one leakproof piece (70) is installed in (101). Therefore, the first wall (131) and the second wall (311) acts as a stopper. The said sealing part (70) essentially It is a gasket. This structure can be seen in Figures 8, 9 and 10. 15 Thanks to the first wall (131) and the second wall (311), the single stopper end- in the current technique The pipe (30) that occurs in the forming structures during assembly or use Leakage and the resulting loss of sealing have been eliminated. This is supported by... The other feature is the form of the inlet opening (31). The inlet opening (31) is stepped 20 degrees towards the outside environment (D). It is configured to have a tapering diameter (see Figure 8). In addition, the sealing part (70) has a special form as shown in Figure 9. This form to obtain it, on its inner surface, in other words on the surface that contacts the inlet opening (31). It contains at least one channel (71). Channel (71) is an arc with a specific radius. Figure 25 As can be seen in picture 9, they can be found in multiple numbers (3 pieces) and in different radii. (for example, the radius of the last channel on the right (71) may be larger). Channel (71) essentially a groove that forms a curved cross-section along the inner surface of the sealing part (70) It is a void. The sealing part (70) also has on its outer surface, i.e. the surface that contacts the protrusion (13) It contains a small crack (72). The mentioned crack (72) extends towards its inner surface. It is a cavity with a cross-section in the form of. It extends around the entire sealing part (70). The leakproof part (70) also includes at least one inclined wall (73). The aforementioned inclined wall is 35 (73) the width of the sealing part (70) will decrease from the inner surface to the outer surface It extends. It is located on both sides. Canal (71), crack (72) and sloping wall 9 (73) thanks to the leak-proof part (70) flexing and contacting the protrusion (13) the gas It ensures a leak-proof seal. Therefore, the water connections to the pipe (30, inlet) together with the protrusion (13) and the inlet (31) The connection from the mouth (31) has been made suitable for quick connection. Heat exchanger 5 (1) The leakage of burnt gas circulating within the line is the special type defined above. It is prevented by a leak-proof part (70) with a special form. With its special form, it is both a heat exchanger on the body (10) and on the pipe (30) the first (131) and second wall (311) to ensure a complete seal in the slot between the stoppers (101) It can be placed. In addition, the end of the pipe (30), namely the inlet opening (31), is directly attached to the body (10). By providing an outlet, the mixing of the waterway (WW) and the gasway has been prevented. The heat exchanger (1) contains at least one insulation element (90). Insulation element (90) Figure As can be seen in 2 and 3, the heat exchanger (1) is to provide heat insulation from below. It is located under the pipe (30). Therefore, 15 occurred inside the body (10). The heat resulting from combustion can be retained inside the shell (10). Housing, fixing of the insulation element (90) and the internal environment (I) of the heat exchanger (1) There is at least one bottom plate (80) to separate the outside environment (O) from the bottom surface. The aforementioned bottom plate (80) has at least one connecting element (100) with the insulation element (90) 20 It is connected through this means. The head of the connecting element (100) is outside the bottom plate (80), as can be seen in Figure 12, In other words, the diameter of the head is below the point where the connecting element (100) passes. It is larger than the diameter of the hole (80) in the bottom plate. In this way, spot bolt 25 in the current technology In connections made by connecting the head, it is possible to pass through the hole in the lower plate (80). problems that occur (e.g. the insulation element (90) the connecting element (100) bottom (80) leaving the hole in the plate and moving towards the inner environment (I etc.) from the middle It has been removed. The connecting element (100) includes at least one extension (102). The extension (102) is located under the head. It is a protrusion in the form of a trapezoidal prism extending from its surface. The extensions (102) are shown in Figure 13. As can be seen, there are multiple of them around the shaft on the underside of the head. Therefore, when the connecting element (100) is mounted to the bottom plate (80), the head These extensions (102) underneath penetrate the bottom plate (80), in other words the bottom plate (80) 35 They begin to deform the plastic. As a result, a stronger connection is formed. is obtained. In addition, the connector (100) contains at least one socket (101). The socket in question (101) also resulted in the plastic deformation of the bottom plate (80) material mentioned above. It is a space filled. The socket (101) is located between the shaft and the extensions (102) on the lower surface of the head. It is a circular groove. The connection is made on both sides as a result of the filling of the bottom plate (80) material into this groove. Movement in that direction is also restricted. 5 As a result, thanks to the connecting element (100), insulation with connecting element (100) the element (90) being perpendicular to each other, or in other words the insulation with the bottom plate (80) The surfaces of the element (90) facing each other will touch each other at every point Their positioning has been ensured in this way. As a result, the insulation in the previous technique was 10. As a result of the disruption of the parallelism of the element (90) to the bottom plate (80), gas leaked between them. Negative consequences such as gas leakage after entry and inefficiency in thermal insulation. It has been eliminated. In light of all that has been described, the invention works as follows: During the operation of the device, 15 Gas is burned in the interior environment (I), defined as the combustion chamber, via the burner (50) and this The hot gas produced by combustion circulates around the pipe (30) and heats the water. Cold water enters the pipe (30) via the water inlet (WI); spiral line along the pipe As it rises, it heats up from the heat it absorbs from the combustion gases and exits the discharge nozzle (WO) hot. It comes out as water. 20 Meanwhile, the separator (20), located between the pipe (30) and the shell (10), allows the burnt gas to escape. It prevents direct contact with the fuselage and heat transfer. The air between the separator and the fuselage The gap creates an additional thermal insulation layer, reducing the amount of heat transferred to the shell and improving thermal insulation. It increases productivity. 25 Sealing element placed inside the groove (41) between the burner (50) and the cover (40) (60), by preventing the hot gas in the combustion chamber from escaping to the outside environment (O) It ensures leak tightness. Also, the inlet opening (31) of the pipe and the protrusion (13) on the body The leak-proof part (70) located between the water circuit and the gas circuit creates a precise 30 By creating a distinction, it prevents mixing. The combination of the bottom plate (80) and the insulation element (90) keeps the heat on the bottom surface, thus preventing the device from absorbing heat. It minimizes heat loss to the outside. 35 Therefore, through the heat exchanger (1), both thermal efficiency and leak tightness can be improved. Significant improvements are achieved. Two located between the pipe (30) and the shell (10) 11 Thanks to the segmented separator (20), the hot gases resulting from combustion are prevented from reaching the surface of the shell (10). direct contact is prevented; in this way the amount of heat transferred to the shell (10) It is falling and unwanted temperature increases on the outer surface are prevented. The separator (20) and the body The air gap created between (10) acts as an additional insulation layer, preventing heat loss. It reduces and increases the overall energy efficiency of the heat exchanger (1). 5 The sealing is placed inside the circular groove (41) between the cover (40) and the burner (50). element (60) prevents the gases formed in the combustion chamber from escaping to the outside environment (O) It makes the seal permanent. This structure, compared to classic flat surface gasket systems... It creates a larger contact surface and provides a long-lasting seal. 10 A specially shaped leak-proof seal is placed between the body (10) and the inlet opening (31) of the pipe (30). part (70) and double stopper (first (131) and second wall (311)) metal end-form structure, water This structure eliminates the risk of the circuit and the gas circuit mixing together. thanks to the pipe (30) slipping back during assembly which happened in the previous technique 15 and problems of mixing of gas and water (WW) lines are prevented, complete water connection is ensured. leak tightness is achieved and the galvanic leakage that may occur due to the use of plastic intermediate elements is avoided. The risks of corrosion and leakage are eliminated. Joining the bottom plate (80) and the insulation element (90) with special connecting elements (100), 20 maintaining perpendicularity tolerance during assembly and preventing connection loosening during long-term use. or prevents problems such as the insulation (90) overflowing into the interior volume. Also the body (10) parts are fixed together with additional mounting lugs, vibration caused It extends the lifespan of the device by reducing deformations. In conclusion, the invention offers higher thermal efficiency, improved gas and water tightness, and assembly. a heat exchanger structure (1) that provides ease, safe working conditions and long service life It offers. The scope of protection of the invention is specified in the claims attached hereto, and these detailed 30 The explanation cannot be limited to those given for illustrative purposes. Because a technically skilled person... the person, without deviating from the main theme of the invention, in light of what has been described above, similar It is clear that these structures can emerge. 12 REFERENCE NUMBERS GIVEN IN THE FIGURE 1 Heat Exchanger Body 11 Part 1, Part 5 12 Second Part 13 Projections 131 The First Wall 14 Connection Strips Separator 10 21 First Separator 22 Second Separator Pipe 31 Inlet Port 311 The Second Wall 15 32 Outlet 33 Curved Forms 40 Covers 41 Grooves 42 Hill 20 50 Burners 60 Sealing Elements 70 Sealing Pieces 71 Channels 72 Slit 25 73 Slanted Wall 80 Subplates 90 Insulation Elements 100 Fasteners 101 Nests 30 102 Extensions (GI) Gas Inlet (I) Indoor Environment (G) Gas (O) Outdoor Environment 35 (WI) Water Inlet (WO) Water Outlet 13 (WW) Waterway
