Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger component and a wall-mounted boiler. Background Art

[0002] As a household heating and hot water equipment, the wall-mounted boiler has experienced significant development and changes in the Chinese market in recent years. With the increasing global attention to carbon emissions and climate change, improving product energy consumption has become an important policy direction for various countries. As a gas or electric heating equipment, the energy consumption of the wall-mounted boiler has received increasing attention.

[0003] Traditional wall-mounted boilers are generally of secondary energy efficiency, which results in serious energy waste. Although fully premixed wall-mounted boilers can achieve primary energy efficiency, they are still too expensive to be widely used in China.

DETAILED DESCRIPTION

[0033] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] In a first aspect, the present application provides a heat exchanger assembly 100 , including: a shell 110 , a water tank 120 , a fan 130 , a smoke exhaust connector 140 , and a baffle 150 .

[0038] Reference Figure 1-7 The heat exchanger assembly 100 includes a housing 110, a water tank 120, a fan 130, a smoke exhaust connector 140, and a baffle 150. The water tank 120 is disposed inside the housing 110, and the water tank 120 is provided with at least one smoke duct. The fan 130 is mounted on the housing 110, and the air outlet of the fan 130 is connected to one end of the smoke duct. The smoke exhaust connector 140 is mounted on the housing 110, and the smoke exhaust connector 140 is connected to the other end of the smoke duct. The baffle 150 is disposed inside the smoke duct.

[0039] It should be noted that the water tank 120 is provided with at least one flue gas duct, that is, the number of flue gas ducts can be one or more. The size and number of the flue gas ducts can be set according to the width of the water tank 120. For example, if six flue gas ducts are set, the six ducts can be divided into two layers, with three flue gas ducts on each layer. At the same time, the six ducts can be divided into three layers, with two flue gas ducts on each layer. The selection can be made according to actual needs and is not limited here. This method increases the heat exchange area and heat exchange distance, and improves the energy utilization efficiency.

[0040] It can be understood that when the number of smoke ducts is set to be multiple, the air outlet of the fan 130 is connected to one end of the multiple smoke ducts, and the smoke exhaust joint 140 is connected to the other end of the multiple smoke ducts.

[0041] Furthermore, the shell 110 is provided with a transverse partition 111, which divides the interior of the shell 110 into an upper cavity 112 and a lower cavity 113. A gap is left between one side of the transverse partition 111 and the inner wall of the shell 110. The fan 130 is connected to the lower cavity 113, and the smoke exhaust joint 140 is connected to the upper cavity 112.

[0042] Reference Figure 1-2 A transverse partition 111 is provided inside the shell 110, and the interior of the shell 110 is divided into an upper cavity 112 and a lower cavity 113 through the transverse partition 111. A gap is left between one side of the transverse partition 111 and the inner wall of the shell 110, and the other side of the transverse partition 111 is connected to the inner wall of the shell 110. The fan 130 is connected to the lower cavity 113, and the smoke exhaust joint 140 is connected to the upper cavity 112.

[0043] It should be noted that the fan 130 blows smoke into the lower part of the shell 110 to the interior of the lower cavity 113, then passes through the smoke duct arranged in the water tank 120, and then enters the upper cavity 112 through the gap left by one side of the transverse partition 111 and the inner wall of the shell 110, and then passes through the smoke duct arranged in the water tank 120, and finally discharges the smoke to the outside through the smoke exhaust joint 140 connected to the upper cavity 112.

[0044] Furthermore, the water tank 120 includes an upper box body 121, a lower box body 122 and a box body connecting pipe 123. The upper box body 121 is arranged in the upper cavity 112 and is provided with a water inlet 124. The lower box body 122 is arranged in the lower cavity 113 and is provided with a water outlet 125. The upper box body 121 and the lower box body 122 are connected through the box body connecting pipe 123.

[0045] Reference Figure 2-4 The water tank 120 includes an upper box body 121, a lower box body 122 and a box body connecting pipe 123. The upper box body 121 is arranged in the upper cavity 112 of the shell 110 and a water inlet 124 is arranged on one side of the water tank 120. The lower box body 122 is arranged in the lower cavity 113 of the shell 110 and a water outlet 125 is arranged on one side of the water tank 120. The upper box body 121 and the lower box body 122 are connected through the box body connecting pipe 123.

[0046] It should be noted that the width of the box connecting pipe 123 arranged in the water tank 120 is close to the gap distance left between one side of the transverse partition 111 and the inner wall of the shell 110. The box connecting pipe 123 is placed in the gap position, one end of the box connecting pipe 123 is connected to the upper box 121, and the other end of the box connecting pipe is connected to the lower box 122, so that the upper box 121 and the lower box 122 are connected through the box connecting pipe 123.

[0047] It should be noted that at least one water inlet 124 is set on one side of the water tank 120, and the water inlet 124 is set on the outer side of the corresponding upper box body 121. At least one water outlet 125 is set on one side of the water tank 120, and the water outlet 125 is set on the outer side of the corresponding lower box body 122.

[0048] It is understandable that the heating water enters from the water inlet 124 of the upper box 121, enters the lower box 122 through the box connecting pipe 123, and then is discharged from the water outlet 125 of the lower box 122. This method increases the heat exchange area, thereby improving the energy utilization efficiency.

[0049] Furthermore, the smoke duct includes at least one first smoke duct 126 and at least one second smoke duct 127 . The first smoke duct 126 is disposed in the lower box body 122 , and the second smoke duct 127 is disposed in the upper box body 121 .

[0050] Reference Figure 2-4 The smoke duct includes at least one first smoke duct 126 and at least one second smoke duct 127 . The first smoke duct 126 and the second smoke duct 127 form a smoke duct. The first smoke duct 126 is disposed in the lower box body 122 , and the second smoke duct 127 is disposed in the upper box body 121 .

[0051] It should be noted that the smoke duct includes a first smoke duct 126 and a second smoke duct 127, and the first smoke duct 126 and the second smoke duct 127 constitute one smoke duct; the smoke duct includes multiple first smoke ducts 126 and multiple second smoke ducts 127, and the multiple first smoke ducts 126 and the multiple second smoke ducts 127 constitute a corresponding multiple smoke ducts.

[0052] In one embodiment, the smoke duct includes a first smoke duct 126 and a second smoke duct 127. The fan 130 blows smoke into the lower part of the shell 110 to the interior of the lower cavity 113, and then passes through the first smoke duct 126, and then enters the upper cavity 112 through the gap left between one side of the transverse partition 111 and the inner wall of the shell 110, and then passes through a second smoke duct 127 arranged in the water tank 120, and finally the smoke is discharged to the outside through the smoke exhaust joint 140 connected to the upper cavity 112.

[0053] In another embodiment, the smoke duct includes a plurality of first smoke ducts 126 and a plurality of second smoke ducts 127, and the fan 130 blows smoke from the lower part of the shell 110 to the interior of the lower cavity 113, and then passes through the plurality of first smoke ducts 126, and then enters the upper cavity 112 through the gap between one side of the transverse partition 111 and the inner wall of the shell 110, and then passes through the plurality of second smoke ducts 127 arranged in the water tank 120, and finally the smoke is discharged to the outside through the smoke exhaust joint 140 connected to the upper cavity 112. This method increases the heat exchange area between the smoke duct and the water tank and the heat exchange distance of the smoke, and improves the energy utilization efficiency.

[0054] Furthermore, the deflector 150 includes a main body 151, a first baffle combination and a second baffle combination. The first baffle combination and the second baffle combination are respectively located on both sides of the main body 151. The first baffle combination is provided with a plurality of first baffles 152 arranged in sequence, and the second baffle combination is provided with a plurality of second baffles 153 arranged in sequence. The first baffles 152 and the second baffles 153 are arranged alternately in sequence.

[0055] Reference Figure 7 The baffle 150 includes a main body 151, a first baffle assembly and a second baffle assembly. The first baffle assembly and the second baffle assembly are respectively located on both sides of the main body 151. The first baffle assembly is provided with a plurality of first baffles 152 arranged in sequence, and the second baffle assembly is provided with a plurality of second baffles 153 arranged in sequence. The first baffles 152 and the second baffles 153 are alternately arranged in sequence. A plurality of first baffles 152 constitute the first baffle assembly, and a plurality of second baffles 153 constitute the second baffle assembly.

[0056] It should be noted that the width of the main body 151 does not exceed the diameter of the smoke duct and matches the smoke duct, the length of a single main body 151 does not exceed the length of a single first smoke duct, and the length of a single main body 151 does not exceed the length of a single second smoke duct.

[0057] It is understandable that the fan blows smoke from the lower part of the shell to the inside of the lower cavity, then passes through the first smoke duct, and then enters the upper cavity through the gap between one side of the transverse partition and the inner wall of the shell, and then passes through the second smoke duct set in the water tank, and finally exhausts the smoke to the outside through the smoke exhaust joint connected to the upper cavity. When the smoke passes through the first smoke duct and the second smoke duct, the smoke will pass through the baffles set inside the first smoke duct and the second smoke duct, and the first baffle combination and the second baffle combination set on the baffle will slow down the heat exchange rate of the smoke, thereby improving the energy utilization efficiency.

[0058] It can be understood that the number of the baffles is equal to the sum of the number of the first flue gas ducts and the number of the second flue gas ducts.

[0059] In one embodiment, the baffles are detachably mounted inside the first smoke duct and the second smoke duct. When the baffles are damaged, only the damaged baffles need to be replaced, which can save costs and improve work efficiency.

[0060] In one embodiment, the baffle is fixedly installed inside the first smoke duct and the second smoke duct. When the baffle is damaged, the entire water tank needs to be replaced.

[0061] It should be noted that the first baffle 152 and the second baffle 153 are substantially consistent in shape and size. The shapes of the first baffle 152 and the second baffle 153 can be semi-arc shapes or other shapes, which can be selected according to actual needs and are not limited here.

[0062] Furthermore, the main body 151 is provided with a plurality of hollow structures 154 , and the hollow structures 154 are located between adjacent first baffles 152 and second baffles 153 .

[0063] Reference Figure 7-8 The main body 151 is provided with a plurality of hollow structures 154, and the hollow structures 154 are located between adjacent first baffles 152 and second baffles 153. The hollow structures 154 are arranged in sequence on the main body 151, and the hollow structures 154 are separated by adjacent first baffles 152 and second baffles 153.

[0064] It should be noted that the smoke passes through the smoke duct through the hollow structure 154. Due to the provision of the first baffle combination and the second baffle combination, the smoke can fully exchange heat with the water in the lower box when passing through the smoke duct, thereby improving the energy utilization efficiency.

[0065] Furthermore, a space corresponding to the transverse partition 111 is reserved between the upper box body 121 and the lower box body 122 .

[0066] Reference Figure 2-4A space corresponding to the transverse partition 111 of the shell 110 is reserved between the upper box body 121 of the water tank 120 and the lower box body 122 of the water tank 120 .

[0067] Furthermore, the lower cavity 113 has a smoke inlet 115 , and a space is left between the smoke inlet 115 and one side of the lower box body 122 .

[0068] Reference Figure 2-4 The lower cavity 113 of the shell 110 has a smoke inlet 115 , and a space is left between the smoke inlet 115 and one side of the lower box body 122 of the water tank 120 .

[0069] It should be noted that the fan blows smoke into the smoke through the smoke inlet 115, reaches the space left between the smoke inlet 115 and one side of the lower box body 122, and then enters the first smoke duct.

[0070] Furthermore, the upper cavity 112 has a smoke outlet 114 , and a space is left between the smoke outlet 114 and one side of the upper box body 121 .

[0071] Reference Figure 2-4 The upper cavity 112 of the shell 110 has a smoke outlet 114 , and a space is left between the smoke outlet 114 and one side of the upper box body 121 of the water tank 120 .

[0072] It should be noted that after the smoke comes out of the second smoke duct, it reaches the space left between the smoke inlet 115 and one side of the lower box body 122, and then the smoke is discharged to the smoke exhaust joint through the smoke outlet 114.

[0073] In one embodiment, water enters from the water inlet 124 of the upper box 121 of the water tank 120, enters the lower box 122 of the water tank 120 through the box connecting pipe 123, and then is discharged from the water outlet 125 of the lower box 122. While the heating water is injected, the fan blows in the smoke through the smoke inlet 115, reaches the space left between the smoke inlet 115 and one side of the lower box 122, enters the first smoke duct 126, exchanges heat with the water in the lower box 122 through the baffle 150, enters the upper cavity 112 through the gap left between one side of the transverse partition 111 and the inner wall of the shell 110, passes through the second smoke duct 127 set in the water tank 120, exchanges heat again in the upper box 121 through the baffle 150, and finally discharges the smoke to the outside through the smoke exhaust joint 140 connected to the upper cavity 112. This method increases the heat exchange area and heat exchange distance, and improves energy utilization efficiency.
