Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and more specifically, to an enhanced heat transfer structure inside a copper tube radiator. Background Technology

[0002] Copper pipe heatsinks are high-efficiency heat dissipation devices made of copper, widely used in electronic equipment, automotive cooling systems, and other fields. CPUs generate a large amount of heat during operation, requiring timely cooling to maintain normal CPU function. Currently, copper pipe heatsinks are the most common solution. A copper pipe heatsink mainly consists of a base, heat-conducting copper pipes, fins, and a fan. During use, the heat generated by the CPU is transferred from the base to the heat-conducting copper pipes, then from the pipes to the fins, and finally, the fan provides rapid heat dissipation.

[0003] Existing copper pipe heat sinks only allow heat to gradually diffuse from the copper pipes to the fins through the contact points, resulting in slow heat transfer and affecting the overall heat dissipation efficiency. Furthermore, dust accumulation on the fins can further degrade heat dissipation. Therefore, this application proposes a novel solution. Utility Model Content

[0004] The purpose of this invention is to address the problem that in existing copper tube radiators, the heat from the heat-conducting copper tube can only be gradually diffused to the entire fins through the contact points with the fins during operation. This results in a slow heat transfer speed, which affects the overall heat dissipation efficiency of the radiator. Furthermore, the fins are prone to dust accumulation during use, leading to a decrease in heat dissipation performance.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The copper tube radiator has an enhanced internal heat transfer structure to improve the above-mentioned problems.

[0007] The application is as follows:

[0008] The device includes a base through which a U-shaped heat-conducting copper pipe is installed. The portion of the heat-conducting copper pipe located on the outer side of the base has multiple evenly distributed fins, all of which are located above the base.

[0009] The portion of the heat-conducting copper tube located on the outside of the base is equipped with an auxiliary heat transfer assembly that cooperates with the fins. The auxiliary heat transfer assembly includes a heat-conducting ring fixedly connected to the outside of the heat-conducting copper tube, and a plurality of heat-conducting plates that are interconnected with the fins are fixedly connected to the outside of the heat-conducting ring.

[0010] A dust filter cover is installed on the top of the base, and the dust filter cover is located on the outside of the plurality of fins. A cooling fan for heat dissipation is installed through the dust filter cover.

[0011] As a preferred technical solution of this application, the heat-conducting copper pipe includes a first pipe located inside the base, and both ends of the first pipe are connected to a second pipe, which is used to connect the fins and the auxiliary heat transfer assembly.

[0012] As a preferred technical solution of this application, the fin has a through hole that cooperates with the heat-conducting copper tube, and a plurality of evenly distributed connecting posts are fixedly connected to the top edge of the fin, the connecting posts being used to connect two adjacent fins.

[0013] As a preferred technical solution of this application, the base includes a mounting bracket and a heat-conducting plate that penetrates the mounting bracket. The heat-conducting plate has mounting holes that cooperate with the heat-conducting copper pipe. Extension plates are fixedly connected to the four corners of the mounting bracket, and screw holes are provided on the extension plates.

[0014] As a preferred technical solution of this application, the auxiliary heat transfer component is installed on the top or bottom of the fin, and the thickness of the auxiliary heat transfer component is less than the gap between two adjacent fins.

[0015] As a preferred technical solution of this application, the dust filter cover includes a housing installed on the top of the base, the housing having multiple evenly distributed air inlets, and a filter screen installed inside the air inlets.

[0016] As a preferred technical solution of this application, a water-cooling assembly is installed on the top of the heat-conducting plate. The water-cooling assembly includes a water-cooling box that is sealed and connected to the heat-conducting plate. A plurality of staggered heat sinks are installed inside the water-cooling box. The bottom ends of the heat sinks are connected to the top of the heat-conducting plate. Liquid inlet pipes and liquid outlet pipes are respectively installed through the two side walls of the water-cooling box.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. By setting auxiliary heat transfer components, the heat transfer path between the fins and the heat-conducting copper pipe can be increased, so that the heat transfer between the fins and the heat-conducting copper pipe is not limited to the connection between the two. This speeds up the heat transfer between the fins and the heat-conducting copper pipe, which can effectively improve the overall heat dissipation efficiency of the heat sink. In use, the heat-conducting ring can quickly transfer the heat of the heat-conducting copper pipe to various parts of the fins through multiple heat-conducting fins, so that the entire fin can be fully utilized. This reduces the number of fins on the heat sink, and further reduces the overall weight and volume of the heat sink.

[0020] 2. By installing a dust filter cover, the cooling fan can expel the air heated by the fins and heat-conducting copper pipes from inside the dust filter cover during use, allowing outside air to enter the interior of the dust filter cover. This accelerates the cooling of the heat-conducting copper pipes. At the same time, the dust filter cover can filter the air entering it, thus preventing dust from accumulating on the surface of the fins and affecting their heat dissipation. It can also prevent dust accumulation on the fin surface from affecting the airflow speed between multiple fins. In addition, the airflow direction of the cooling fan is horizontal with the gaps between the fins, which can better improve airflow and thus quickly blow away the generated heat, improving the heat dissipation effect.

[0036] like Figures 1-7 As shown, this embodiment proposes an enhanced heat transfer structure inside a copper tube radiator, including a base 1.

[0037] A U-shaped heat-conducting copper pipe 3 is installed through the base 1. Multiple evenly distributed fins 2 are installed on the part of the heat-conducting copper pipe 3 located on the outside of the base 1. All the fins 2 are located above the base 1.

[0038] The portion of the heat-conducting copper pipe 3 located on the outside of the base 1 is equipped with an auxiliary heat transfer component 4 that cooperates with the fins 2. The auxiliary heat transfer component 4 includes a heat-conducting ring 401 fixedly connected to the outside of the heat-conducting copper pipe 3. Multiple heat-conducting plates 402 that are connected to the fins 2 are fixedly connected to the outside of the heat-conducting ring 401. By setting the auxiliary heat transfer component 4, the heat transfer path between the fins 2 and the heat-conducting copper pipe 3 can be increased, so that the heat transfer between the fins 2 and the heat-conducting copper pipe 3 is not limited to the connection part between the two, thus accelerating the heat transfer speed between the fins 2 and the heat-conducting copper pipe 3 and effectively improving the overall heat dissipation efficiency of the heat sink. In use, the heat-conducting ring 401 can quickly transfer the heat of the heat-conducting copper pipe 3 to various positions of the fins 2 through the multiple heat-conducting plates 402, so that the entire fins 2 can be fully utilized, thereby reducing the number of fins 2 on the heat sink and further reducing the overall weight and volume of the heat sink.

[0039] A dust filter cover 5 is installed on the top of the base 1. The dust filter cover 5 is located on the outside of multiple fins 2. A cooling fan 6 for heat dissipation is installed through the dust filter cover 5. By setting the dust filter cover 5, the cooling fan 6 can exhaust the air heated by the fins 2 and the heat-conducting copper pipes 3 inside the dust filter cover 5 during use, allowing outside air to enter the interior of the dust filter cover 5, accelerating the cooling of the heat-conducting copper pipes 3. At the same time, the dust filter cover 5 can filter the air entering it, thereby preventing dust from accumulating on the surface of the fins 2 and affecting the heat dissipation of the fins 2. It can also prevent the dust accumulated on the surface of the fins 2 from affecting the airflow speed between the multiple fins 2. In addition, the airflow direction of the cooling fan 6 is horizontal with the gap between the fins 2, which can better improve airflow and thus quickly blow away the generated heat, improving the heat dissipation effect.

[0040] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the heat-conducting copper pipe 3 further includes a first pipe 301 located inside the base 1, with second pipes 302 connected to both ends of the first pipe 301. The second pipes 302 are used to connect the fins 2 and the auxiliary heat transfer assembly 4. It should be noted that the first pipe 301 enables the heat from the heat-conducting plate 102 to be transferred to the second pipe 302, and the second pipe 302 facilitates the installation of the fins 2 and the auxiliary heat transfer assembly 4.

[0041] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, a further step is to have through holes 7 that cooperate with the heat-conducting copper pipe 3 through the fin 2. Multiple evenly distributed connecting posts 8 are fixedly connected to the top edge of the fin 2, and the connecting posts 8 are used to connect two adjacent fins 2. It should be noted that, in use, the through holes 7 facilitate the installation of the fins 2 on the heat-conducting copper pipe 3, and the connecting posts 8 support and connect two adjacent fins 2. Simultaneously, the connecting posts 8 can also transfer heat between multiple fins 2, increasing the overall heat dissipation area and improving the heat dissipation speed.

[0042] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the base 1 further includes a mounting bracket 101 and a heat-conducting plate 102 penetrating the mounting bracket 101. The heat-conducting plate 102 has mounting holes 103 that cooperate with the heat-conducting copper pipe 3. Extension plates are fixedly connected to the four corners of the mounting bracket 101, and screw holes 104 are provided on the extension plates. It should be noted that the mounting bracket 101 facilitates the installation of the heat-conducting plate 102 and the dust filter 5; the extension plates and screw holes 104 facilitate the installation of the mounting bracket 101; and the mounting holes 103 facilitate the penetration of the heat-conducting copper pipe 3 through the heat-conducting plate 102.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the auxiliary heat transfer component 4 is further installed on the top or bottom of the fin 2, and the thickness of the auxiliary heat transfer component 4 is smaller than the gap between two adjacent fins 2. It should be noted that the auxiliary heat transfer component 4, with a thickness smaller than the gap between two fins 2, can avoid affecting the airflow velocity between multiple fins 2.

[0044] like Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the dust filter hood 5 further includes a housing 501 mounted on the top of the base 1. The housing 501 has multiple evenly distributed air inlets 502, and a filter screen 503 is installed inside each air inlet 502. It should be noted that during use, the air entering the housing 501 through the air inlets 502 is filtered by the filter screen 503, thereby preventing dust from entering the interior of the housing 501.

[0045] like Figure 1 and Figure 8As shown, in a preferred embodiment, based on the above method, a water-cooling assembly 9 is further installed on the top of the heat-conducting plate 102. The water-cooling assembly 9 includes a water-cooling box 901 that is sealed and connected to the heat-conducting plate 102. A plurality of staggered heat sinks 904 are installed inside the water-cooling box 901. The bottom ends of the heat sinks 904 are connected to the top of the heat-conducting plate 102. Liquid inlet pipes 902 and liquid outlet pipes 903 are respectively installed through the two side walls of the water-cooling box 901. It should be noted that during use, the water-cooling component 9 works in conjunction with the fins 2, heat-conducting copper pipes 3, auxiliary heat transfer components 4, and cooling fan 6 to dissipate heat, improving the heat dissipation effect of the radiator. Both the inlet pipe 902 and the outlet pipe 903 pass through the dust filter 5. During use, the cooling heat enters the interior of the water-cooling box 901 through the inlet pipe 902 and is then discharged through the outlet pipe 903, thereby cooling the heat-conducting plate 102 and multiple heat sinks 904, improving the heat dissipation efficiency of the radiator. By setting up the heat sinks 904, the heat of the heat-conducting plate 102 can be transferred to the coolant flowing inside the water-cooling box 901 more quickly. Moreover, the multiple heat sinks 904 arranged in an alternating manner can slow down the flow speed of the coolant inside the water-cooling box 901, increase the contact time between the coolant and the heat-conducting plate 102 and the heat sinks 904, and improve the heat dissipation effect.

[0046] Specifically, the working principle of the enhanced heat transfer structure inside this copper pipe radiator is as follows: During use, the heat-conducting plate 102 can transfer heat to the second pipe 302 through the first pipe 301. The second pipe 302 can diffuse the heat to the fins 2 and the auxiliary heat transfer components 4. At the same time, the heat-conducting ring 401 can transfer the heat from the second pipe 302 to various positions of the fins 2 through multiple heat-conducting plates 402. During heat dissipation, the cooling fan 6 can exhaust the air inside the dust filter 5, allowing fresh air from the outside to enter the interior of the dust filter 5 to cool the fins 2, the heat-conducting copper pipe 3, and the auxiliary heat transfer components 4. During use, the water-cooling component 9 can work with the fins 2, the heat-conducting copper pipe 3, the auxiliary heat transfer components 4, and the cooling fan 6 to perform dual heat dissipation, improving the heat dissipation efficiency of the radiator. During use, the dust filter 5 can filter dust in the air to prevent dust from accumulating on the fins 2.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
