Description

Technical Field

[0001] This utility model belongs to the technical field of copper busbar radiators, specifically relating to a new type of high-efficiency heat dissipation copper busbar. Background Technology

[0002] Computer components utilize a large number of integrated circuits. As is well known, high temperatures are the biggest enemy of integrated circuits. High temperatures can not only lead to unstable system operation and shorten the lifespan of the system, but may even cause some components to burn out. Most of the heat that causes high temperatures comes from inside the integrated circuits. The role of the heat sink is to absorb this heat and then dissipate it inside or outside the computer case to ensure that the computer components maintain a normal temperature.

[0003] The material of heat sink fins refers to the specific material used for them. Each material has different thermal conductivity, arranged from highest to lowest: silver, copper, aluminum, and steel. However, using silver for heat sink fins would be too expensive, so copper is the best option. Copper heat sinks have a robust structure and a large heat dissipation area, providing efficient heat transfer and dissipation within a limited space. They are suitable for cooling in high-power or complex environments such as servers, industrial equipment, and automotive engines.

[0004] Existing copper busbar radiators, relying solely on their own heat dissipation performance, may not be able to meet the heat dissipation needs of high-power equipment. They are not easy to quickly dissipate the heat conducted on the copper busbar, resulting in low heat dissipation efficiency, which will affect the heat dissipation efficiency and effect, and also affect the normal operation of the equipment. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a new type of high-efficiency heat dissipation copper busbar. This new high-efficiency heat dissipation copper busbar enables the coolant inside the tree-shaped heat dissipation pipe structure to circulate, thereby achieving a good liquid cooling effect and accelerating the heat transfer inside the trapezoidal copper busbar. The heat dissipation fans on both sides can form a flow channel between the ventilation hood and the trapezoidal copper busbar, which can not only accelerate the heat dissipation of the trapezoidal copper busbar, but also cool the pumping mechanism, thereby effectively improving the heat dissipation efficiency and heat dissipation effect of the copper busbar.

[0006] A novel high-efficiency heat dissipation copper busbar includes a heat dissipation base and a top fixing frame. A trapezoidal copper busbar with an increased heat dissipation area is fixedly connected to the upper surface of the heat dissipation base. The top fixing frame is fixedly connected to the top of the trapezoidal copper busbar. The trapezoidal copper busbar has an interconnected tree-like heat dissipation pipe structure inside. Ventilation hoods are fixedly connected to both sides of the trapezoidal copper busbar, and an auxiliary heat dissipation mechanism is provided on the side of the ventilation hood away from the trapezoidal copper busbar. A cooling fan is fixedly installed on the top of the ventilation hood. One of the ventilation hoods has a pumping mechanism inside that can communicate with the tree-like heat dissipation pipe structure.

[0007] Preferably, the trapezoidal copper busbar is composed of multiple parallel trapezoidal heat dissipation fins, all of which are vertically fixed to the upper surface of the heat sink, with the wider side of the trapezoidal heat dissipation fins facing downwards and fixedly connected to the heat sink.

[0008] Preferably, the tree-shaped heat dissipation pipe structure includes tree-shaped heat dissipation pipes and connecting pipes. The number of tree-shaped heat dissipation pipes is five, and three of them are horizontally embedded in the bottom of the trapezoidal copper busbar and connected in series with each other through the connecting pipe. The other two tree-shaped heat dissipation pipes are horizontally embedded in the middle part of the trapezoidal copper busbar and connected in series with each other through the connecting pipe and connected to the three tree-shaped heat dissipation pipes at the bottom. The interior of the tree-shaped heat dissipation pipe structure and the pumping mechanism are filled with coolant.

[0009] Preferably, the auxiliary heat dissipation mechanism includes a Y-shaped heat sink and heat dissipation grooves. There are several Y-shaped heat sinks, and all of them are fixedly connected to each other and vertically fixed to the side of the ventilation hood. Heat dissipation grooves are provided on the side of both the ventilation hood and the Y-shaped heat sinks. Both ventilation hoods are fixedly connected to the inclined parts on both sides of the trapezoidal copper busbar by bolts.

[0010] Preferably, the pumping mechanism includes a water pump, an inlet pipe, and an outlet pipe. The inlet pipe and the outlet pipe are both connected to the inlet end and the outlet end of the water pump. The end of the inlet pipe away from the water pump is connected to the outlet end of the tree-shaped heat dissipation pipe near the middle of the trapezoidal copper busbar. The end of the outlet pipe away from the water pump is connected to the inlet end of the tree-shaped heat dissipation pipe near the bottom of the trapezoidal copper busbar.

[0011] Preferably, the number of cooling fans is eight, and the eight cooling fans are evenly divided into two groups. The two groups of cooling fans are fixedly installed on the top of the two ventilation hoods. The cooling fan on the top of the ventilation hood with the built-in pumping mechanism blows air from the outside of the ventilation hood to the inside, while the cooling fan on the top of the other ventilation hood blows air from the inside of the ventilation hood to the outside, so that a smooth airflow can be formed inside the two ventilation hoods and the trapezoidal copper busbar.

[0012] The beneficial effects of the above technical solution are as follows:

[0013] This novel high-efficiency heat dissipation copper busbar utilizes a trapezoidal copper busbar, a tree-like heat dissipation pipe structure, an auxiliary heat dissipation mechanism, cooling fans, and a pumping mechanism. The trapezoidal copper busbar increases the contact area, improving heat dissipation efficiency. The tree-like heat dissipation pipe structure is completely embedded inside the trapezoidal copper busbar, providing a large contact area. The pumping mechanism circulates the coolant within the tree-like heat dissipation pipe structure, achieving excellent liquid cooling and accelerating heat transfer within the trapezoidal copper busbar. The auxiliary heat dissipation mechanism increases the heat dissipation area, providing some cooling effect to the hot air passing through the ventilation shroud. Simultaneously, the cooling fans on both sides create airflow channels within the ventilation shroud and trapezoidal copper busbar, accelerating heat dissipation from the trapezoidal copper busbar and cooling the pumping mechanism, thereby effectively improving the heat dissipation efficiency and performance of the copper busbar.

[0019] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 4 The embodiments are described in detail below.

[0020] This embodiment provides a novel high-efficiency heat dissipation copper busbar, as shown in the attached figure. Figure 1-4 As shown, it includes a heat sink 1 and a top mounting bracket 2. A trapezoidal copper busbar 3, which increases the heat dissipation area, is fixedly connected to the upper surface of the heat sink 1. The heat sink 1 can be fixedly installed on the structure that needs heat dissipation. Heat is conducted through the heat sink 1 and then transferred to the trapezoidal copper busbar 3. The trapezoidal copper busbar 3 is composed of multiple parallel trapezoidal heat dissipation fins. The multiple trapezoidal heat dissipation fins are all vertically fixedly connected to the upper surface of the heat sink 1, and the wide side of the trapezoidal heat dissipation fins is fixedly connected to the heat sink 1 with the wide side facing down. This can increase the heat conduction area of ​​the trapezoidal heat dissipation fins and quickly conduct heat to the interior of the trapezoidal copper busbar 3.

[0021] The top fixing bracket 2 is fixedly connected to the top of the trapezoidal copper busbar 3, which can fix multiple trapezoidal copper busbars 3 and ensure the overall structural integrity. The trapezoidal copper busbar 3 has an interconnected tree-like heat dissipation pipe structure inside. The tree-like heat dissipation pipe structure includes tree-like heat dissipation pipes 6 and connecting pipes 7. There are five tree-like heat dissipation pipes 6, three of which are horizontally embedded in the bottom of the trapezoidal copper busbar 3 and connected in series through the connecting pipes 7. The tree-like heat dissipation pipes 6 on both sides are opposite in direction to the tree-like heat dissipation pipe 6 in the middle, so that the three tree-like heat dissipation pipes 6 are evenly embedded in the interior of the trapezoidal copper busbar 3, ensuring that it evenly dissipates heat from multiple trapezoidal heat dissipation fins. For heat conduction, two additional tree-shaped heat dissipation pipes 6 are horizontally embedded in the middle part of the trapezoidal copper busbar 3 and are connected in series with each other through a connecting pipe 7 and connected to the three tree-shaped heat dissipation pipes 6 at the bottom. All five tree-shaped heat dissipation pipes 6 are connected in series with each other and connected to the pumping mechanism. The tree-shaped heat dissipation pipes 6 can effectively expand the heat dissipation area of ​​the coolant and improve the heat dissipation efficiency. The interior of the tree-shaped heat dissipation pipe structure and the pumping mechanism are filled with coolant. The pumping mechanism can make the coolant in the tree-shaped heat dissipation pipe structure circulate, thereby quickly dissipating the heat from the trapezoidal heat dissipation fins and cooling it through the cooling fan 5.

[0022] Both sides of the trapezoidal copper busbar 3 are fixedly connected to ventilation hoods 4, and an auxiliary heat dissipation mechanism is provided on the side of the ventilation hood 4 away from the trapezoidal copper busbar 3. The auxiliary heat dissipation mechanism includes Y-shaped heat dissipation plates 8 and heat dissipation grooves 9. There are several Y-shaped heat dissipation plates 8, and all of them are fixedly connected to each other and vertically fixed to the side of the ventilation hood 4. The Y-shaped heat dissipation plates 8 can increase the heat dissipation area and conduct heat inside the trapezoidal copper busbar 3 more efficiently, thereby improving the heat dissipation effect. Heat dissipation grooves 9 are opened on the side of both the ventilation hood 4 and the Y-shaped heat dissipation plates 8. Both ventilation hoods 4 are fixedly connected to the inclined parts on both sides of the trapezoidal copper busbar 3 by bolts. The heat dissipation grooves 9 can promote air circulation inside the trapezoidal copper busbar 3 and the ventilation hood 4, thereby effectively promoting the heat dissipation effect of the copper busbar.

[0023] Eight cooling fans 5 are fixedly installed on the top of the ventilation shroud 4, and the eight cooling fans 5 are evenly divided into two groups. The two groups of cooling fans 5 are fixedly installed on the top of the two ventilation shrouds 4 respectively. The cooling fan 5 on the top of the ventilation shroud 4 with a built-in pumping mechanism blows air from the outside of the ventilation shroud 4 to the inside. It can not only blow air into the trapezoidal copper busbar 3 to promote airflow, but also blow directly into the water inlet pipe 11 and water outlet pipe 12 to cool the coolant flowing through the water inlet pipe 11 and water outlet pipe 12, so that the coolant can always maintain a relatively low temperature to dissipate heat from the trapezoidal copper busbar 3. The cooling fan 5 on the top of the other ventilation shroud 4 blows air from the inside of the ventilation shroud 4 to the outside. This can form a smooth airflow channel between the two ventilation shrouds 4 and the trapezoidal copper busbar 3, ensuring that the cooling fan 5 can keep the air inside the trapezoidal copper busbar 3 circulating at all times and promote heat dissipation.

[0024] One of the ventilation hoods 4 has a pumping mechanism inside that can communicate with the tree-like heat dissipation pipe structure. The pumping mechanism includes a water pump 10, an inlet pipe 11, and an outlet pipe 12. The inlet pipe 11 and the outlet pipe 12 are both connected to the inlet and outlet ends of the water pump 10. The end of the inlet pipe 11 away from the water pump 10 is connected to the outlet end of the tree-like heat dissipation pipe 6 near the middle of the trapezoidal copper busbar 3. The end of the outlet pipe 12 away from the water pump 10 is connected to the inlet end of the tree-like heat dissipation pipe 6 near the bottom of the trapezoidal copper busbar 3. After the water pump 10 is running, it can make the tree-like heat dissipation pipe 6, the tree-like heat dissipation pipe 6, and the outlet pipe 12 connected to the tree-like heat dissipation pipe 6. The coolant circulates within pipe 7, inlet pipe 11, and outlet pipe 12. The tree-shaped heat dissipation pipe 6 contacts the trapezoidal heat dissipation fins, allowing the circulating coolant to exchange heat with them. This heat is transferred from the fins to the coolant, while the coolant dissipates heat during its flow. Simultaneously, the cooling fan 5 above inlet pipe 11 and outlet pipe 12 rapidly cools the coolant flowing through them, resulting in a better heat exchange effect and thus improving the overall heat dissipation efficiency of the copper busbar radiator.

[0025] Both the cooling fan 5 and the water pump 10 are electrically connected to the external control unit and are electrically connected to the external circuit via wires.

[0026] In summary, the usage steps of this new high-efficiency heat dissipation copper busbar are as follows:

[0027] 1. The heat sink 1 is attached and fixed to the heat source by bolts. The heat emitted by the heat source will be conducted to the trapezoidal copper busbar 3. The multiple trapezoidal heat dissipation fins in the trapezoidal copper busbar 3 can perform preliminary heat dissipation.

[0028] 2. Simultaneously, the cooling fans 5 and water pump 10 on both sides are operated. The cooling fans 5 on both sides have air intake on one side and air exhaust on the other side, which can form a flow channel inside the trapezoidal copper busbar 3, thereby rapidly cooling the trapezoidal copper busbar 3. The heat dissipation area can be increased through the Y-shaped heat sink 8. The cooling fans 5 on both sides can also generate airflow in the heat dissipation grooves 9 on the side of the Y-shaped heat sink 8, which has a certain cooling effect on the Y-shaped heat sink 8.

[0029] 3. After the water pump 10 is running, the coolant flows from the outlet pipe 12 of the water pump 10 into the tree-shaped heat dissipation pipe 6. After passing through all the tree-shaped heat dissipation pipes 6, it flows into the water pump 10 from the inlet pipe 11, forming a circulation loop. This allows the coolant in the tree-shaped heat dissipation pipe 6, the connecting pipe 7, the inlet pipe 11, and the outlet pipe 12 to circulate. The tree-shaped heat dissipation pipe 6 is in contact with the trapezoidal heat dissipation fins. The circulating coolant can exchange heat with the trapezoidal heat dissipation fins, transferring the heat from the trapezoidal heat dissipation fins to the coolant. The coolant can dissipate heat during its flow. The cooling fan 5 can quickly cool the coolant flowing through the inlet pipe and the outlet pipe 12, giving the circulating coolant a better heat exchange effect, thereby improving the overall heat dissipation efficiency of the copper busbar radiator.

[0030] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
