Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating element technology, and more specifically to a heating assembly. Background Technology
[0002] In special production equipment, hot air is needed to dry the processed parts. However, traditional hot air devices usually involve installing heating wires inside the air duct of the device to directly heat the gas inside the air duct.
[0003] However, the production needs of some specialized equipment require that the heating gas not contain metal ions. For example, in the production of photovoltaics and chips, nitrogen gas needs to be heated on the production line. If the heating gas contains metal ions, it will lead to quality defects in the photovoltaic panels and chips. However, for the manufacturing and assembly of hot air blowers, it is difficult to avoid the presence of metal materials and components in their components. Therefore, when using existing conventional hot air blowers for drying in these types of specialized equipment, unstable product quality often occurs, leading to losses in production efficiency. This has become a problem that urgently needs to be solved. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to invent a heating component that can prevent the presence of metal ions in the gas after heating.
[0005] The present invention adopts the following technical solution:
[0006] A heating assembly, comprising:
[0007] The tank body has a first pipe body inside it. The two ends of the first pipe body are respectively connected to the tank body. A first flow channel is formed between the tank body and the first pipe body. One end of the tank body is provided with a first air inlet communicating with the first pipe body and a second air inlet communicating with the first flow channel. The other end of the tank body is provided with a first air outlet communicating with the first pipe body and a second air outlet communicating with the first flow channel.
[0008] The second tube is disposed inside the first tube, and a second flow channel is formed inside the second tube. The first tube, the second tube, and the tank are all made of non-metallic materials.
[0009] The first air inlet and the first air outlet are both located on the axis of the tank body. There are multiple second air inlets and multiple second air outlets. The multiple second air inlets are arranged in a circular array with the first air outlet as the center, and the multiple second air outlets are arranged in a circular array with the first air outlet as the center.
[0010] A heating unit is disposed between the first tube and the second tube.
[0011] Furthermore, multiple first pipe bodies are provided and evenly arranged within the tank. Multiple first air inlets, multiple second air outlets, multiple second pipe bodies, and multiple heating units are provided corresponding to the first pipe bodies. Multiple second air inlets and multiple second air outlets are provided, with multiple second air inlets evenly arranged at one end of the tank and multiple second air outlets evenly arranged at the other end of the tank. A connecting pipe extends outward from the edge of the second air inlet.
[0012] Furthermore, the heating unit is a heating resistor sleeved on the outside of the second tube.
[0013] Furthermore, the tank body consists of a tubular body and end caps fixed at both ends of the body.
[0014] Furthermore, the first tube, the second tube, and the tank are all made of quartz glass.
[0015] Furthermore, the tank body is provided with an insulation layer on the outside.
[0016] Beneficial effects:
[0017] This invention, by placing the heating unit outside the second tube, avoids direct contact between the heating unit and the gas inside the second tube, thus preventing the heated gas from carrying metal ions. Simultaneously, the canister encloses the second tube, maximizing the utilization of the heating unit's external heat and minimizing heat loss, thereby improving heat efficiency. Furthermore, the first tube, fitted over the second tube, separates the heating unit from the gas inside the canister, forming a first flow channel for gas circulation, preventing the gas inside the tube from contacting the heating unit and carrying metal ions during heating. Moreover, due to the heating... When the unit is heated, its inner and outer sides heat up simultaneously, and the heat generated by the inner and outer sides is basically the same. Therefore, in order to make the temperature of the gas discharged from the first air outlet and the second air outlet tend to be the same and not have a large temperature difference, the first air inlet and the first air outlet are both set on the axis of the tank body, and multiple second air inlets and multiple second air outlets are provided. The multiple second air inlets are arranged in a circumferential array with the first air outlet as the center, and the multiple second air outlets are arranged in a circumferential array with the first air outlet as the center, so that the heating unit installed between the first tube and the second tube can uniformly heat the gas flowing through the first flow channel.

[0030] like Figure 1-4 As shown, a heating assembly includes:
[0031] The tank body 10 has a first pipe 20 inside it. The two ends of the first pipe 20 are connected to the tank body 10. A first flow channel is formed between the tank body 10 and the first pipe 20. One end of the tank body 10 is provided with a first air inlet 1021 communicating with the first pipe 20 and a second air inlet 1022 communicating with the first flow channel. The other end of the tank body 10 is provided with a first air outlet communicating with the first pipe 20 and a second air outlet communicating with the first flow channel.
[0032] The second tube 30 is disposed inside the first tube 20, and a second flow channel is formed inside the second tube 30. The first tube 20, the second tube 30 and the tank 10 are all made of non-metallic materials.
[0033] The first air inlet 1021 and the first air outlet are both located on the axis of the tank body 10. There are multiple second air inlets 1022 and multiple second air outlets. The multiple second air inlets 1022 are arranged in a circular array with the first air outlet as the center, and the multiple second air outlets are arranged in a circular array with the first air outlet as the center.
[0034] A heating unit is disposed between the first tube 20 and the second tube 30.
[0035] During the heating process, some gas will flow into the first flow channel through the second air inlet 1022 and then be discharged from the second air outlet. The remaining gas will flow into the second flow channel through the first air inlet 1021 and then be discharged from the first air outlet. During this process, the heating unit located between the first tube 20 and the second tube 30 will simultaneously heat the first tube 20 and the second tube 30, thereby heating the gas inside the first tube 20 and outside the second tube 30, rather than directly contacting the gas for heating, thus effectively avoiding the presence of metal ion components in the heated gas.
[0036] This invention, by placing the heating unit outside the second tube 30, avoids direct contact between the heating unit and the gas inside the second tube 30, thus preventing the heated gas from carrying metal ions. Simultaneously, the canister 10 encloses the second tube 30, fully utilizing the external heat of the heating unit, reducing heat loss, and improving heat utilization. Furthermore, the first tube 20, fitted outside the second tube 30, separates the heating unit from the gas inside the canister 10, forming a first flow channel for gas circulation, preventing the gas inside the tube from contacting the heating unit and carrying metal ions during heating. Moreover, due to the addition of… When the heating unit heats up, its inner and outer sides heat up simultaneously, and the amount of heat generated on the inner and outer sides is basically the same. Therefore, in order to make the temperature of the gas discharged from the first air outlet and the second air outlet tend to be the same and not have a large temperature difference, the first air inlet 1021 and the first air outlet are both set on the axis of the tank body 10. Multiple second air inlets 1022 and multiple second air outlets are provided. Multiple second air inlets 1022 are arranged in a circular array with the first air outlet as the center, and multiple second air outlets are arranged in a circular array with the first air outlet as the center, so that the heating unit installed between the first tube body 20 and the second tube body 30 can uniformly heat the gas flowing through the first flow channel.
[0037] In addition, to improve the heating effect, such as Figure 5 and Figure 6 As shown, multiple first tube bodies 20 are provided and evenly arranged inside the tank 10. Multiple first air inlets 1021, second air outlets, second tube bodies 30, and heating units are provided corresponding to the first tube bodies 20 to improve the heating effect by adding multiple heating units. At the same time, multiple second air inlets 1022 and second air outlets are provided, with multiple second air inlets 1022 evenly arranged at one end of the tank 10 and multiple second air outlets evenly arranged at the other end of the tank 10, so that multiple heating units can evenly heat the gas in the first flow channel. In order to ensure that the gas discharged from the first air outlet and the second air outlet has the same temperature and to avoid temperature difference, and to facilitate the entry and exit of gas into and out of the first flow channel, connecting pipes 1023 extend outward from the edges of the second air inlets 1022 and the second air outlets.
[0038] Preferably, for ease of installation, in this embodiment, the heating unit is a heating resistor sleeved on the outside of the second tube 30.
[0039] Furthermore, to facilitate the installation of the first tube 20 and the second tube 30, in this embodiment, the tank 10 is composed of a tubular body 101 and end caps 102 fixed at both ends of the body 101. During installation and use, the first tube 20 can be installed on one end cap 102 first, and then the end cap 102 can be welded or glued to the body 101. Then, the other end cap 102 can be fixed to the body 101, and the second tube 30, which is externally fitted with a heating unit, can be inserted into the first tube 20.
[0040] Specifically, in this embodiment, the first tube 20, the second tube 30, and the tank 10 are all made of quartz glass.
[0041] In order to improve the heating effect of the heating unit, in this embodiment, the wall thickness of the first tube 20 is set to 2.0 cm and the wall thickness of the second tube 30 is set to 1.5 cm, so as to facilitate the rapid transfer of heat to the inside of the first tube 20 and the outside of the second tube 30 to heat the gas. In order to reduce heat loss, in this embodiment, the wall thickness of the first tube 20 is smaller than the wall thickness of the tank 10, and an insulation layer is provided on the outside of the tank 10.
[0042] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
