Description

Technical Field

[0001] This invention relates to the field of aluminum radiators, and more specifically to a structurally integrated aluminum radiator. Background Technology

[0002] Currently, aluminum radiators are characterized by their beautiful appearance, light weight, good heat dissipation performance, and energy-saving effect. They are also lighter and cheaper to manufacture than copper radiators, making them suitable for mass production. They are widely used in industries such as automobiles, power generation equipment, construction machinery, home appliances, and agricultural machinery.

[0003] Existing aluminum profile radiators used in automobiles and some construction machinery are prone to accumulating dust, lint, or fibers. Furthermore, the thin plates and small diameter of the radiators can easily clog the air vents, reducing their heat dissipation efficiency. To improve heat dissipation efficiency and drive airflow within the radiator, small air pumps are often required. However, given the limited internal space and significant vibrations in automobiles and some construction machinery, installing external small air pumps presents new design challenges. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a structurally integrated aluminum radiator. This solves the issues of existing aluminum profile radiators having thinner panels and smaller vent pipe diameters, which easily clog the vent pipes that allow air to circulate inside the radiator, reducing its heat dissipation efficiency. Furthermore, to improve heat dissipation efficiency and drive airflow within the aluminum profile radiator, a small air pump is often required. However, this is problematic for vehicles and some construction machinery, where internal space is limited and vibrations are significant. The use of an external small air pump introduces new design challenges.

[0005] The technical solution adopted in this invention is as follows:

[0006] An integrated aluminum heat sink includes: a plate body, with reinforcing sections on both sides of the plate body, the reinforcing sections being located at the lower part of the surface of the plate body; a coil connecting the two reinforcing sections is provided inside the plate body; an installation cavity is provided in the reinforcing section; a detachable heat dissipation assembly is installed in the installation cavity; the heat dissipation assembly includes a guide tube; an axial flow fan is installed in the middle of the guide tube; the axial flow fan includes an axial flow motor; a fan blade cover is installed on the output shaft of the axial flow motor; multiple fan blades are installed on the fan blade cover; the fan blade cover is installed at one end near the air inlet of the guide tube; a detachable rotating rod is installed at the center of the fan blade cover; filter blades are installed on the rotating rod; an extension tube is installed at the rear end of the central axis of the axial flow motor; a filter screen is installed at the end of the extension tube.

[0007] This invention solves the technical problem that "the limited internal space of automobiles and some construction machinery, coupled with their significant vibrations, makes the use of external small air pumps a new design challenge." It utilizes a built-in axial flow fan within the reinforced section of the plate to drive airflow through the coil. In conjunction with the front-mounted filter blades, the axial flow motor drives the fan blade cover and blades to rotate, which in turn drives the filter blades to rotate. This rotation removes lint and fibers, while the filter screen filters out large dust particles, preventing dust accumulation inside the coil.

[0008] Optionally, the plate body is provided with multiple positioning posts. The positioning posts in this invention are used to fix the plate body.

[0009] Optionally, the axial flow motor has a housing on its outer side, and the guide tube has an outer cylinder in the outer region of the axial flow motor, with a pair of outer tubes penetrating the housing inside the outer cylinder.

[0010] Optionally, a horizontal tube is installed on the extension tube, and the wires of the axial flow motor pass through the extension tube and enter the outer tube via the horizontal tube. In this invention, the wires of the axial flow motor pass through the extension tube and enter the outer tube via the horizontal tube, which facilitates connection to an external power source.

[0011] Optionally, the guide tube is connected to the coil via a bend, and the filter screen is located at the bottom of the bend.

[0012] Optionally, the filter blade has a cavity in the middle, and a first clamping frame and a second clamping frame are provided on both sides of the filter blade. The first clamping frame and the second clamping frame each include a horizontal piece located on the front of the filter blade and a side piece located on the side of the filter blade.

[0013] Optionally, the side panels of the first clamping frame and the side panels of the second clamping frame are connected by a first elastic cord.

[0014] Optionally, the horizontal plates of the first clamping frame and the second clamping frame are connected by a second elastic rope. A fan-shaped first side filter is mounted on the second elastic rope. A plurality of inclined second side filters are fixed on the second elastic rope between the first side filter and the horizontal plate. The end of the filter blade is provided with a fixing post. The fixing post is located on the same side as the first side filter. A third elastic rope is provided between the first side filter and the fixing post. A plurality of inclined third side filters are fixed on the third elastic rope. The first side filter, the second side filter, and the third side filter are made of a material that adsorbs dust.

[0015] Optionally, multiple second-side filter elements are deflected toward the same side. Multiple third-side filter elements are also deflected toward the same side as the second-side filter elements.

[0016] Optionally, the plate is equipped with multiple mounting posts.

[0017] Optionally, multiple heat dissipation fins are arranged on both the top and bottom of the plate, and the heat dissipation fins are perpendicular to the plate.

[0018] The beneficial effects of the present invention include at least the following:

[0019] 1. This invention solves the technical problem that "the internal space of automobiles and some construction machinery is limited and the vibration is relatively large, and the setting of an external small air pump brings new design difficulties" by driving airflow through the axial flow fan built into the reinforcing part of the plate. In addition, the front filter blades remove more fibrous material and fibers during rotation, and filter out large dust particles by using a filter screen to avoid dust accumulation in the coil.

[0020] 2. In this invention, the wires of the axial motor are passed through the extension tube and then through the horizontal tube into the outer tube, which facilitates connection to an external power source.

[0021] 3. The axial flow motor of this invention drives the fan blade cover and fan blades to rotate, which in turn drives the filter blades to rotate. Due to centrifugal force, the first side filter moves outward. The first side filter pulls the third elastic rope to extend, increasing the spacing between the third side filter on the third elastic rope. At the same time, it pulls the second elastic rope, increasing the spacing between the second side filter on the second elastic rope. As the filter blades rotate, larger dust particles and fibers or flocs (with greater centrifugal force) in the airflow are thrown onto the side wall of the outer cylinder. The spacing between the first and third side filter blades near the edge of the filter blades is smaller, making it easier to block and adsorb dust, and more effective at blocking fibers or flocs. This avoids excessive entry of fibers or flocs into the fan blades. Smaller dust particles or small amounts of fibers or flocs are blocked by the filter screen at the end of the extension tube, minimizing the entry of dust, fibers, or flocs into the coil.

[0022] 4. In this invention, the axial flow motor drives the fan blade cover and fan blade to rotate, which in turn drives the filter blade to rotate. Due to the centrifugal force, the first side filter plate moves outward, causing the first clamping frame and the second clamping frame to rub against the filter blade to generate static electricity, which adsorbs dust and fibers or flocculent matter, thereby improving the filtration efficiency.

[0023] 5. In this invention, the filter screen forms a certain angle with the bend. Since the wind speed is low at the bend (where the wind direction changes drastically), the filter screen can easily capture dust and a small amount of fiber or lint. Attached Figure Description

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the invention.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Example 1:

[0035] The technical solution adopted in this invention is as follows:

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this invention discloses a structurally integrated aluminum heat sink, comprising: a plate body 1, with reinforcing portions 2 on both sides of the plate body, the reinforcing portions being located at the lower part of the surface of the plate body; a coil 3 connecting the two reinforcing portions being disposed within the plate body; a mounting cavity 4 being disposed within the reinforcing portion; a detachable heat dissipation assembly 5 being disposed within the mounting cavity; the heat dissipation assembly including a guide tube 6; an axial flow fan 7 being mounted in the middle of the guide tube; the axial flow fan including an axial flow motor 8; a fan blade cover 9 being mounted on the output shaft of the axial flow motor; multiple fan blades 10 being mounted on the fan blade cover; the fan blade cover being installed at one end near the air inlet of the guide tube; a detachable rotating rod 11 being mounted at the center of the fan blade cover; filter blades 12 being mounted on the rotating rod; an extension tube 13 being mounted at the rear end of the central axis of the axial flow motor; and a filter screen 14 being mounted at the end of the extension tube. Multiple positioning posts 15 are provided on the plate body. Multiple heat dissipation fins 16 are arranged on both the top and bottom of the plate body, the heat dissipation fins being perpendicular to the plate body. The axial flow motor has a housing 17 on its outer side, and the guide tube is located in the outer region of the axial flow motor with an outer cylinder 18. The outer cylinder contains a pair of outer tubes 19 that penetrate the housing.

[0037] A horizontal tube 20 is mounted on the extension tube, and the wires of the axial flow motor pass through the extension tube and enter the outer tube via the horizontal tube. The guide tube is connected to the coil through a bend 21.

[0038] In this embodiment, the heat dissipation component is removed promptly when it becomes dirty.

[0039] In this embodiment, the axial flow fan built into the reinforcing part of the plate drives the airflow to flow in the coil, and together with the front filter blades, removes more fibrous material and fibers during rotation.

[0040] Example 2:

[0041] The difference between Example 2 and Example 1 is that, as Figure 5 As shown, the filter blade has a cavity 22 in the middle, and a first clamping frame 23 and a second clamping frame 24 are provided on both sides of the filter blade. The first clamping frame and the second clamping frame each include a horizontal piece 25 located on the front of the filter blade and a side piece 26 located on the side of the filter blade. The side pieces of the first clamping frame and the side pieces of the second clamping frame are connected by a first elastic rope 27.

[0042] The horizontal plates of the first and second clamping frames are connected by a second elastic rope 28. A fan-shaped first side filter 29 is mounted on the second elastic rope. Multiple inclined second side filter 30s are fixed to the second elastic rope between the first side filter and the horizontal plate. A fixing post 31 is provided at the end of each filter blade, located on the same side as the first side filter. A third elastic rope 32 is provided between the first side filter and the fixing post, and multiple inclined third side filter 33s are fixed to the third elastic rope. In this embodiment, the first, second, and third elastic ropes are all made of high-temperature resistant elastic material. In this embodiment, the multiple second side filter 30s are deflected towards the same side. The multiple third side filter 30s are deflected towards the same side as the second side filter 30s. The first, second, and third side filter 30s are made of dust-adsorbing material.

[0043] In this embodiment, the first side filter, the second side filter, and the third side filter are made of one or more of the following: polyester, polypropylene, and other chemical fibers, membrane filter media, and glass fiber.

[0044] In this embodiment, the axial flow motor drives the fan blade cover and fan blades to rotate, which in turn drives the filter blades to rotate. Due to centrifugal force, the first side filter moves outward. The first side filter pulls the third elastic rope to extend, increasing the spacing between the third side filter on the third elastic rope. At the same time, it pulls the second elastic rope, increasing the spacing between the second side filter on the second elastic rope. As the filter blades rotate, larger dust particles and fibers or flocs (with greater centrifugal force) in the airflow are thrown onto the side wall of the outer cylinder. The spacing between the first and third side filter blades near the edge of the filter blades is smaller, making it easier to block and adsorb dust, and more effective at blocking fibers or flocs. This prevents excessive fibers or flocs from entering the fan blades. Smaller dust particles or small amounts of fibers or flocs are blocked by the filter screen at the end of the extension tube, minimizing the entry of dust, fibers, or flocs into the coil.

[0045] Example 3:

[0046] The difference between Example 3 and Example 2 is that the surfaces of the first clamping frame and the second clamping frame are made of wool or synthetic fiber fabric, and the filter blades are made of glass or plastic.

[0047] In this embodiment, the axial flow motor drives the fan blade cover and fan blade to rotate, which in turn drives the filter blade to rotate. Due to the centrifugal force, the first side filter moves outward, causing the first clamping frame and the second clamping frame to rub against the filter blade to generate static electricity, which adsorbs dust, fibers or flocculent matter, thus improving the filtration efficiency.

[0048] Example 4:

[0049] The difference between Example 4 and Example 1 is that, as Figure 6 As shown, the filter screen is located at the bottom of the bend.

[0050] In this embodiment, the filter screen forms a certain angle with the bend. Since the wind speed is low at the bend (where the wind direction changes drastically), the filter screen can easily capture dust and a small amount of fiber or lint.

[0051] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
