Description

Technical Field

[0001] The present application relates to the technical field of fan equipment, and in particular to an air collecting box and a manufacturing method thereof. Background Art

[0002] Air collector is a broad device, usually refers to the equipment used to collect, guide or control the flow of air in industrial production environment. This kind of air collector can be found in many industrial applications, such as ventilation system, dust removal system, air purification system or air conditioning system. It is mainly used to collect air in the working area, which may contain dust, smoke, harmful gases, etc.; to guide the air to a specific direction or equipment, such as to send it to the filtration system for purification; to balance the air pressure in the system by adjusting the air volume, to ensure the pressure balance of stable air flow, and to reduce noise.

[0003] The air conditioning air box usually refers to a component in the air conditioning system that is used to concentrate and guide the flow of air. In a central air conditioning system, the air box (sometimes also called a mixing box) is a device used to collect air from different sources (such as fresh air, return air, etc.) and mix it evenly. The design of the air box helps ensure that the air is evenly distributed, thereby improving the efficiency and performance of the air conditioning system.

[0004] In the prior art, the structure of the air conditioning air collecting box is relatively fixed, and most of the parts are connected by glue. It is impossible to simply adjust the structure according to the actual use scenario, which is not conducive to rapid production and warehousing. At the same time, there are a lot of sheet metal and welding operations in the production process, which leads to large material loss and easy pollution, posing a safety hazard. And because it generally uses thinner materials such as single-layer thin iron sheets as the box body of the air collecting box, this may lead to the following problems:

[0005] 1. Insufficient strength: Thinner materials may cause the air box to deform or become damaged when subjected to a certain amount of pressure, especially when subjected to external forces or changes in internal air pressure.

[0006] 2. Vibration and noise: Thinner panels are prone to vibration, especially when wind speeds are high or uneven, which may increase noise levels and affect the user experience.

[0007] 3. Reduced thermal insulation performance: If the air collecting box is used for heating and cooling air conditioning systems, thinner materials may lead to poor thermal insulation, which in turn affects the energy efficiency of the air conditioning system and increases energy consumption.

[0008] 4. Sealing problem: Thin-walled materials may be difficult to ensure good sealing due to manufacturing process limitations, resulting in air leakage and affecting the efficiency and stability of air flow.

[0009] 5. Difficult installation and maintenance: Materials that are too thin may be more easily bent or damaged during the installation process, causing inconvenience to installation and subsequent maintenance.

[0010] 6. Shortened service life: Due to the above factors, a thinner air box may have a shorter service life than a properly designed air box.

[0011] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Summary of the invention

[0012] Based on this, it is necessary to provide a high-strength air collecting box and a manufacturing method thereof.

[0046] Embodiment 1:

[0047] See also Figure 1 to Figure 2 The present application provides an air collecting box, comprising a first box body 1 and a second box body 2 fixedly mounted on the outside of the first box body 1, wherein the first box body 1 has an air inlet connection port 11 and an air flow port 12, and the second box body 2 has an air outlet 21. The airflow entering the first box body 1 from the air inlet connection port 11 can flow out of the second box body 2 through the air flow port 12 and the air outlet 21 in sequence, thereby ensuring the air collecting and diversion functions of the air collecting box.

[0048] The airflow port 12 is provided on a side wall 13 of the first box body 1, and the air outlet 21 is provided on an outer wall 22 of the second box body 2 which is different from the side wall 13 where the airflow port 12 is located. There is a spacing 3 between the first box body 1 and the second box body 2, and the airflow port 12, the spacing 3 and the air outlet 21 form an airflow channel. The airflow entering the first box body 1 from the air inlet connection port 11 flows along the airflow channel to the air outlet 21, thereby achieving smooth flow of the entire airflow. In addition, the double-layer box structure of the first box body 1 and the second box body 2 can significantly improve the overall structural strength of the air collecting box, making it more sturdy and durable, not easily deformed or damaged by vibration caused by external pressure or internal airflow, and improve the thermal insulation effect, which helps to reduce energy loss, improve the energy efficiency of the air conditioning system, effectively reduce the noise generated when the air conditioning equipment is running, create a quieter working or living environment, improve the overall sealing of the air collecting box, prevent air leakage, ensure the stable operation of the system, and have stronger structural strength and better corrosion resistance, which means that the air collecting box can have a longer service life and reduce the frequency of maintenance and replacement.

[0049] Specifically, in this embodiment, the first box body 1 and the second box body 2 are connected and fixed by diagonal electric welding. Diagonal spot welding is a commonly used welding technology, which is usually used for the connection between metal components, especially for structural parts that do not need to be completely welded. In this connection method, the welding points are set along the diagonal direction of the component to ensure the stability and strength of the structure. It has the advantages of reducing the use of welding materials, avoiding the extra weight caused by continuous welding, and the process is relatively simple and fast, which can reduce processing time and cost, can be completed in a shorter time, improve efficiency, and because spot welding only heats at specific points, it reduces the scope of the heat-affected zone, which helps to maintain the original characteristics of the material.

[0050] In other embodiments, the corresponding connection method of the first box body 1 and the second box body 2 may be selected according to actual conditions, such as full welding, etc., as long as it can meet actual needs, and no specific limitation is made here.

[0051] In this embodiment, the airflow openings 12 are through holes with a diameter of 6 mm, and at least two groups of airflow openings 12 are provided. The two groups of airflow openings 12 are arranged in parallel on the same side wall 13, and each group of airflow openings 12 is arranged at least 5 at equal intervals, thereby ensuring the regularity and continuity of the airflow. The first box 1 is provided with two side walls 13 having airflow openings 12, and the two side walls 13 having airflow openings 12 are arranged on the first box 1 opposite to each other, so as to ensure that the airflow between the first box 1 and the second box 2 is symmetrical and avoid the generation of turbulence.

[0052] In other embodiments, the size and arrangement of the corresponding air flow openings 12 may be selected according to actual conditions, as long as they can meet actual needs, and no specific limitation is made here.

[0053] In order to further increase the stability of the airflow, in the present embodiment, the air outlet 21 is also set as a through hole with a diameter of 6 mm. There are at least two groups of air outlets 21. The two groups of air outlets 21 are arranged in parallel on the same side wall 13. Each group of air outlets 21 is arranged with at least 5 air outlets 21 at equal intervals, so that the difference in aperture between the air outlet 12 and the air outlet 21 is not too large to cause the airflow velocity to be too fast, thereby ensuring the stability of the airflow.

[0054] In other embodiments, the size and arrangement of the air outlets 21 may be selected according to actual conditions, as long as they can meet actual needs, and no specific limitation is made here.

[0055] As mentioned above, in this embodiment, the outer wall 22 where the air outlet 21 is located and the side wall 13 where the air inlet connection port 11 are located are arranged parallel to each other, so that the airflow entering the first box body 1 from the air inlet connection port 11 is also uniform when it is dispersed to the airflow ports 12 on the two side walls 13, thereby ensuring that the airflow in the entire air collecting box is regular and stable.

[0056] It is worth noting that the outer wall 22 where the air outlet 21 is located and the side wall 13 where the air outlet 12 is located are arranged perpendicular to each other, so that the distances between the two side walls 13 with the air outlet 12 and the air outlet 21 are equal, and the airflows generated on both sides are also consistent, further enhancing the airflow stability in the box.

[0057] In order to facilitate maintenance and observation, in this embodiment, the first box body 1 and the second box body 2 are both provided with a side door 4, and the side doors 4 on the first box body 1 and the second box body 2 are located on the same side. When inspecting, the two side doors 4 can be opened in sequence, which is simple and convenient. Among them, the material of the side door 4 is a transparent material, such as an acrylic plate, etc., which can have a perspective effect and facilitate observation of the situation inside the box. The size of the side door 4 of the first box body 1 is 150x150mm, and the size of the side door 4 of the first box body 1 is 250x250mm.

[0058] The air collecting box also includes sealing strips arranged around the side door 4 to seal the connection between the side door 4 and the box body, ensuring that the air flow does not overflow at the connection between the side door 4 and the box body when the side door 4 is closed, thereby improving the air tightness of the air collecting box and ensuring the flow stability of the internal air flow.

[0059] In order to facilitate the installation of the air collecting box, connecting ears 5 are extended and fixed at the four corners of the second box body 2, and the air collecting box can be fixed to the required area through the connecting ears 5.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
