Description

Technical Field

[0001] This utility model relates to the technical field of multi-layer nested composite heat sinks, and in particular to a multi-layer nested composite heat sink. Background Technology

[0002] Multi-layer nested composite radiators are a type of high-efficiency heating equipment, mostly used for home heating. They improve the heat dissipation area through structural optimization and material combination, and promote air circulation with the flow hole design.

[0003] Residential multi-layer nested composite radiators typically employ a multi-layer concentric fin design, forming parallel or series flow channels. The inner layers are primarily constructed of copper or stainless steel (corrosion resistant and high pressure-bearing capacity), while the middle layers often utilize aluminum alloy (high thermal conductivity for rapid heat transfer). The outer surface is coated with an oxidation-resistant coating or decorative metal. However, to further improve heating efficiency, a typical residential multi-layer nested composite radiator consists of at least two multi-layer nested flow channel plates. The outer walls of these multiple multi-layer nested flow channel plates are fitted with heat dissipation fins to increase the surface area in contact with air. However, after prolonged use, both the outer walls of the two multi-layer nested flow channel plates and the outer surfaces of the heat dissipation fins will... The presence of a large amount of dust, lint, and other contaminants (in actual use, dust in the air adheres to the outer surface of the heat sink fins and multi-layer nested flow channel plates; if the dust is not cleaned in time, the dust, lint, and other contaminants form a heat insulation layer on the outer surface of the heat sink fins and multi-layer nested flow channel plates) hinders heat transfer. Regular cleaning of the outer surface of the heat sink fins and multi-layer nested flow channel plates is required to improve heat conduction efficiency. However, the existing two multi-layer nested flow channel plates are connected by welding, and their outer surfaces cannot be disassembled for cleaning. Therefore, cleaning tools such as brushes are needed to clean from a specific angle, which increases the difficulty and tediousness of cleaning the contaminants on the outer surface of the multi-layer nested flow channel plates and heat sink fins. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-layer nested composite heat sink, which aims to improve the problems in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-layer nested composite heat sink, comprising:

[0006] Two multi-layer nested flow channel plates are fixedly installed on their outer walls with heat dissipation fins for heating air. One of the multi-layer nested flow channel plates has multiple conduits that communicate with its own inner cavity fixedly installed on one side, and the other multi-layer nested flow channel plate has multiple connecting pipes that are compatible with the conduits fixedly installed on one side.

[0007] The assembly / disassembly unit is located inside multiple conduits. It allows multiple conduits to be connected to multiple connecting pipes and seals the joints between the conduits and connecting pipes.

[0013] Multiple conduits and connecting tubes are fixedly fitted with sealing rings at one end, and a sealing ring is fixedly installed at the end fitted to the outer wall of the connecting tube. The sealing ring fitted to the outside of the conduit has an annular sealing groove that matches the sealing ring at one end.

[0014] As a further description of the above technical solution:

[0015] Ratchet rings are fixedly sleeved on the outer walls of multiple drive columns, and ratchet teeth for limiting the ratchet rings are slidably installed in the inner cavities of multiple fixed tubes. A top pressure spring is fixedly installed at one end of each ratchet tooth.

[0016] As a further description of the above technical solution:

[0017] The outer walls of multiple fixed tubes are fixedly installed with positioning tubes that communicate with their own inner cavities. Positioning pins are slidably installed in the inner cavities of multiple positioning tubes. One end of each positioning pin is rotatably connected to one end of a ratchet.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-8 One embodiment of this utility model is a multi-layer nested composite heat sink, comprising:

[0032] Two multi-layer nested flow channel plates 1 are fixedly installed on their outer walls with heat dissipation fins 4 for heating air. The two multi-layer nested flow channel plates 1 can provide flow channels for hot water. The hot water inside the two multi-layer nested flow channel plates 1 transfers heat to the heat dissipation fins 4. Since the heat dissipation fins 4 are in direct contact with the air, the thermal conductivity is increased by 30% to 50%, thereby accelerating the heating speed of the air and enabling the indoor air to heat up quickly (this is existing technology and will not be described in detail here).

[0033] One of the multi-layer nested flow channel plates 1 has multiple conduits 2 that communicate with its own inner cavity fixedly installed on one side. Another multi-layer nested flow channel plate 1 has multiple connecting pipes 3 that are compatible with the conduits 2 fixedly installed on one side. One of the multi-layer nested flow channel plates 1 has four conduits 2 fixedly installed on one side with heat dissipation fins 4, and another multi-layer nested flow channel plate 1 has four connecting pipes 3 fixedly installed on one side with heat dissipation fins 4. Water supply pipes that communicate with their own inner cavities are fixedly installed on the outer walls of two adjacent conduits 2. Hot water can be supplied to the two multi-layer nested flow channel plates 1 through one of the water supply pipes. The hot water flows through the two multi-layer nested flow channel plates 1 and flows out through the other water supply pipe, thereby providing hot water to the two multi-layer nested flow channel plates 1. The heat of the hot water is transferred to the surrounding air through the heat dissipation fins 4, thus achieving the purpose of heating the surrounding air.

[0034] The diameter of the end of the connecting pipe 3 away from the outer wall of the multi-layer nested flow channel plate 1 is smaller than the inner diameter of the conduit 2. The diameter of the large end of the connecting pipe 3 is the same as the diameter of the conduit 2. When the two multi-layer nested flow channel plates 1 are in use, the small ends of multiple connecting pipes 3 are inserted into the inner cavities of multiple conduits 2 respectively until the large end of the connecting pipe 3 contacts one end of the connecting pipe 2, thus realizing the initial connection between multiple connecting pipes 3 and conduits 2.

[0035] A positioning gear 8 is rotatably installed in the inner cavity of multiple conduits 2, and a rack 16 that engages with the positioning gear 8 is fixedly installed in the inner cavity of multiple connecting tubes 3. The end of the rack 16 away from the connecting tube 3 extends to the outside of the connecting tube 3. When the small end of the connecting tube 3 is inserted into the inner cavity of the conduit 2, the end of the rack 16 away from the large end of the connecting tube 3 is inserted directly below the positioning gear 8. As the connecting tube 3 is continuously inserted into the inner cavity of the conduit 2, the rack 16 engages with the positioning gear 8, causing the positioning gear 8 to rotate continuously along its own axis.

[0036] A sealing ring 6 is fixedly fitted to one end of multiple conduits 2 and one end of connecting pipe 3. The sealing ring 6 fitted outside the connecting pipe 3 is flush with the connection between the large end and the small end of the connecting pipe 3. When the large end of the connecting pipe 3 away from the multi-layer nested flow channel plate 1 is attached to one end of the conduit 2, the sealing ring 6 fitted outside the connecting pipe 3 and the conduit 2 is tightly attached to each other.

[0037] A sealing ring 15 is fixedly installed at one end of the connecting pipe 3, which is sleeved on the outer wall of the connecting pipe 3. A sealing ring 6, which is sleeved on the outside of the conduit 2, has an annular sealing groove that matches the sealing ring 15 at one end. After the sealing ring 6, which is sleeved on the outside of the connecting pipe 3 and the outside of the conduit 2, is tightly fitted together, the end of the sealing ring 15 away from the sealing ring 6 is inserted into the inner cavity of the annular sealing groove until the end of the sealing ring 15 is fitted with the inner wall of the annular sealing groove away from its own opening.

[0038] One end of each of the multiple positioning gears 8 is fixedly mounted with a drive column 5, and one end of the multiple drive columns 5 extends to the outside of the conduit 2. The thickness of the sealing ring 15 is greater than the depth of the annular sealing groove. When the end of the sealing ring 15 away from the sealing ring 6 is in contact with the inner wall of the annular sealing groove away from its own opening end, the ends of two adjacent sealing rings 6 cannot be in contact. When hot water flows from the conduit 2 into the inner cavity of the connecting pipe 3, hot water will leak from the connection between the conduit 2 and the connecting pipe 3. In order to improve the sealing between the conduit 2 and the connecting pipe 3, the drive column 5 is continuously rotated, so that the positioning gear 8 rotates around its own central axis. This allows the rack 16 to continuously move into the interior of the conduit 2. At this time, the sealing ring 15 is squeezed and deformed, and continuously squeezes the inner wall of the annular sealing groove until two adjacent sealing rings 6 are tightly in contact, thus sealing the connection between the conduit 2 and the connecting pipe 3 and preventing hot water from leaking from the connection between the conduit 2 and the connecting pipe 3.

[0039] Multiple drive columns 5 are rotatably sleeved with fixed pipes 7. A sealed bearing is fixedly installed in the inner cavity of the fixed pipe 7. The inner wall of the sealed bearing is fixedly connected to the outer wall of the drive column 5. Through the cooperation of the fixed pipe 7 and the sealed bearing, not only can the drive column 5 rotate along its own axis, but also hot water can be prevented from overflowing through the fixed pipe 7.

[0040] Based on the applicant's understanding of the prior art, when hot water flows from the conduit 2 to the connecting pipe 3, the water flow will impact the inner wall of the connecting pipe 3, causing the connecting pipe 3 to move slightly away from the conduit 2. This will still cause hot water to leak from the connection between the connecting pipe 3 and the conduit 2, thus affecting the normal use of the heat exchanger.

[0041] To solve the above technical problems, ratchet rings 12 are fixedly sleeved on the outer walls of multiple drive columns 5, and ratchet teeth 13 for limiting the ratchet rings 12 are slidably installed in the inner cavities of multiple fixed tubes 7. A top pressure spring 11 is fixedly installed at one end of each ratchet tooth 13. The ratchet teeth 13 can unidirectionally limit the rotation direction of the ratchet rings 12. When the rack 16 moves into the conduit 2 and causes the positioning gear 8 to rotate, the ratchet rings 12 rotate together with the drive columns 5. The inclined sidewall of the rotating ratchet rings 12 continuously impacts the inclined sidewall of the ratchet teeth 13, thereby causing the ratchet teeth 13 to move up and down. When the ratchet teeth 13 move up and down, the top pressure spring 11 is continuously compressed and extended, so that the ratchet teeth 13 can position the ratchet rings 12 in a stationary state and prevent the ratchet rings 12 from rotating in the opposite direction. This can avoid the situation where the connecting pipe 3 moves slightly when hot water impacts the inner wall of the connecting pipe 3, thus preventing hot water from leaking from the connection between the connecting pipe 3 and the conduit 2 and avoiding adverse effects on the normal use of the heat exchanger.

[0042] Each of the multiple fixed tubes 7 has a positioning tube 10 fixedly installed on its outer wall, which communicates with its own inner cavity. Positioning pins 14 are slidably installed in the inner cavity of each of the multiple positioning tubes 10. One end of each positioning pin 14 is rotatably connected to one end of a ratchet 13. Multiple positioning blocks 9 are symmetrically fixedly installed on the outer wall of each positioning pin 14. Each end of the multiple positioning tubes 10 has a ring-shaped limiting groove adapted to the positioning blocks 9. When the ratchet 13 moves up and down, the positioning pins 14 move along with it, and the multiple positioning blocks 9 move along the inner cavity of the limiting groove. When it is necessary to release the ratchet 13 from the ratchet ring 12, the positioning pins 14 are pulled upwards until the multiple positioning blocks 9 are completely removed from the multiple limiting grooves. The pin is removed from the inner cavity and then rotated along the axis of the positioning pin 14 until the multiple positioning blocks 9 are completely misaligned with the multiple limiting grooves. Then the lifting force on the positioning pin 14 is released. At this time, the positioning pin 14 is moved down under the action of the top pressure spring 11 until the bottom of the multiple positioning blocks 9 and the top of the positioning tube 10 are in contact. This releases the ratchet 13 from the ratchet ring 12, allowing the connecting tube 3 to move away from the conduit 2. This separates the two multi-layer nested flow channel plates 1, making it easier to clean the outer walls of the two multi-layer nested flow channel plates 1 and the heat dissipation fins 4 from different angles using a brush. This reduces the difficulty and tediousness of cleaning the dirt on the outer surfaces of the two multi-layer nested flow channel plates 1 and the heat dissipation fins 4.

[0043] The positioning gear 8, rack 16, conduit 2, connecting pipe 3, sealing ring 15, sealing ring 6, ratchet ring 12, and ratchet 13 constitute the disassembly and assembly parts. The disassembly and assembly parts can realize the interconnection of multiple conduits 2 and multiple connecting pipes 3, and realize the sealing of the connection between conduits 2 and connecting pipes 3. This makes it easier to use a brush to clean the outer walls of the two multi-layer nested flow channel plates 1 and heat dissipation fins 4 from different angles, reducing the difficulty and tediousness of cleaning the dirt on the outer surface of the two multi-layer nested flow channel plates 1 and heat dissipation fins 4.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
