Description

Technical Field

[0001] The utility model relates to the field of hardware die-castings, in particular to high-efficiency heat dissipation hardware die-castings. Background Art

[0002] ‌‌Metal die-casting is a type of part that is cast in a shape and size restricted by the mold by forcing molten metal into the mold under high pressure. Metal die-casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. This process is similar to injection molding, and the mold is usually made of a higher-strength alloy.

[0003] During use, metal die-castings are used in electronic or mechanical equipment. These devices generate heat during operation. Generally, the heat dissipation base and fins of metal die-castings are responsible for dissipating the heat generated by the equipment. The metal die-castings currently used have water-cooled heat dissipation systems, but in most cases they are installed together at the location of the metal die-castings. The overall space is relatively sealed. Although it can prevent dust from entering, the space is relatively closed and heat is easy to accumulate in local areas. If the heat cannot be discharged to the outside of the equipment in time, the internal temperature of the equipment will increase.

[0004] Therefore, a high-efficiency heat dissipation hardware die-casting is proposed. Utility Model Content

[0005] In view of the above problems, the present invention provides a high-efficiency heat dissipation hardware die-casting to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is:

[0007] A high-efficiency heat-dissipating hardware die-casting comprises a hardware die-casting, a heat sink, and a hardware die-casting mounting plate. The heat sink is fixed to the surface of the hardware die-casting, and both the hardware die-casting and the heat sink are located inside the hardware die-casting mounting plate. A first heat dissipating pipe is fixedly mounted on the heat dissipating top surface of the heat sink, a second heat dissipating pipe is arranged above the first heat dissipating pipe, a symmetrically arranged circulation conveying pipe is connected between the first heat dissipating pipe and the second heat dissipating pipe, the top end of the circulation conveying pipe passes through the hardware die-casting mounting plate and is connected to a cooling box, an installation slot is provided on the top surface of the hardware die-casting mounting plate, and the width of the installation slot is greater than the diameter of the second heat dissipating pipe.

[0008] In a further technical solution, a protective cover is fixedly connected to the top surface of the hardware die-casting mounting plate, the side wall of the protective cover is provided with evenly spaced blowing fans, the inner wall of the blowing fans is fixedly connected with vents, and the side of the protective cover away from the blowing fans is provided with evenly spaced air outlets.

[0009] Through the above technical solution, the airflow generated by the equidistantly distributed blowing fans opened on the side wall of the protective cover can actively promote air flow. When the air is acted upon by the blowing fans, it quickly enters the interior of the protective cover through the vents and can quickly take away the heat generated by components such as hardware die-castings and heat sinks.

[0010] In a further technical solution, the top surface of the second heat dissipation tube is fixedly connected with equidistantly distributed fins, and the gap direction of the fins is consistent with the outlet direction of the blowing fan.

[0011] Through the above technical solution, the air blown out by the fan can flow in a specific direction, and the direction of the gap between the fins is consistent with the outlet direction of the fan, so that the air can flow through the gap between the fins more smoothly, and can take away the heat on the fins faster, thereby improving the heat dissipation efficiency.

[0012] In a further technical solution, the fins are S-shaped.

[0013] Through the above technical solution, when air flows through the S-shaped fins, due to the curved shape of the fins, the air will form a flow path on the fin surface, so that the contact time and contact area between the air and the fin surface are increased, further improving the heat transfer effect.

[0014] In a further technical solution, an air-permeable net is fixedly connected to the inner wall of the mounting slot, and the outer surface of the second heat dissipation pipe is embedded in the center of the surface of the air-permeable net.

[0015] Through the above technical solution, the breathable net on the inner wall of the installation slot can ensure air circulation on the one hand, and prevent foreign matter from entering the installation slot on the other hand, thereby protecting the second heat dissipation pipe. The outer surface of the second heat dissipation pipe is embedded in the center of the surface of the breathable net, so that air can better contact the second heat dissipation pipe, thereby improving heat dissipation efficiency.

[0016] In a further technical solution, connecting columns are fixedly connected at the four corners of the top surface of the hardware die-casting, the top ends of the connecting columns are threadedly connected with fastening nuts, and the top surface of the hardware die-casting mounting plate is provided with rectangularly distributed connecting holes, and the top ends of the connecting columns pass through the inner walls of the connecting holes.

[0017] Through the above technical solution, the hardware die-casting is fixedly installed inside the hardware die-casting installation plate by fastening the nut for threaded connection.

[0018] In a further technical solution, a dust screen is fixedly connected to the inner wall of the air outlet.

[0019] The above technical solution can prevent dust from entering the interior of the protective cover.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By arranging the first heat dissipation tube and the second heat dissipation tube on the surface of the heat sink, and the mounting slots and the breathable net arranged at the position of the hardware die-casting mounting plate, compared with the existing technology, it can have the effect of being installed inside the hardware die-casting mounting plate while having upward ventilation and maintaining comprehensive heat dissipation. In addition, the fins arranged on the surface of the second heat dissipation tube are consistent with the blowing direction of the blower fan, and the fins are in an S-shaped structure, which can further improve the efficiency of heat dissipation of the second heat dissipation tube, thereby improving the heat dissipation effect of the hardware die-casting when it is installed and used as a whole.

[0031] Example:

[0032] See also Figure 1-4 , high-efficiency heat dissipation hardware die-casting, including a hardware die-casting 1, a heat sink 2, and a hardware die-casting mounting plate 3. The heat sink 2 is fixed on the surface of the hardware die-casting 1, and the hardware die-casting 1 and the heat sink 2 are both located inside the hardware die-casting mounting plate 3. A first heat dissipation pipe 4 is fixedly installed on the heat dissipation top surface of the heat sink 2, and a second heat dissipation pipe 5 is arranged above the first heat dissipation pipe 4. A symmetrically arranged circulation conveying pipe 6 is connected between the first heat dissipation pipe 4 and the second heat dissipation pipe 5. The top of the circulation conveying pipe 6 passes through the hardware die-casting mounting plate 3 and is connected to a cooling box 7. An installation slot 8 is provided on the top surface of the hardware die-casting mounting plate 3, and the width of the installation slot 8 is greater than the diameter of the second heat dissipation pipe 5.

[0033] See also Figure 1 and Figure 2 The top surface of the hardware die-casting mounting plate 3 is fixedly connected with a protective cover 11, the side wall of the protective cover 11 is provided with equidistantly distributed blowing fans 13, the inner wall of the blowing fan 13 is fixedly connected with a vent 12, and the side of the protective cover 11 away from the blowing fan 13 is provided with equidistantly distributed air outlets 14.

[0034] The airflow generated by the equidistantly distributed blowing fans 13 opened on the side wall of the protective cover 11 can actively promote the air flow. When the air is quickly fed into the protective cover 11 through the vents 12 under the action of the blowing fans 13, it can quickly take away the heat generated by components such as the metal die-casting 1 and the heat sink 2.

[0035] See also Figure 1 and Figure 3 The top surface of the second heat dissipation tube 5 is fixedly connected with equidistantly distributed fins 10 , and the gap direction of the fins 10 is consistent with the outlet direction of the blowing fan 13 .

[0036] The air blown out by the blowing fan 13 can flow in a specific direction, and the gap direction of the fins 10 is consistent with the outlet direction of the blowing fan 13, so that the air can flow through the gaps between the fins 10 more smoothly, and can take away the heat on the fins 10 more quickly, thereby improving the heat dissipation efficiency.

[0037] See also Figure 3 , fin 10 is S-shaped.

[0038] When air flows through the S-shaped fins 10 , due to the curved shape of the fins 10 , the air forms a flow path on the surface of the fins 10 , thereby increasing the contact time and area between the air and the surface of the fins 10 , further improving the heat transfer effect.

[0039] See also Figure 1 and Figure 4 The inner wall of the mounting slot 8 is fixedly connected with a breathable net 9 , and the outer surface of the second heat dissipation pipe 5 is embedded with the center of the surface of the breathable net 9 .

[0040] The breathable mesh 9 on the inner wall of the mounting slot 8 can ensure air circulation on the one hand, and prevent foreign matter from entering the mounting slot 8 on the other hand, thereby protecting the second heat dissipation tube 5. The outer surface of the second heat dissipation tube 5 is embedded in the center of the surface of the breathable mesh 9, so that air can better contact the second heat dissipation tube 5, thereby improving heat dissipation efficiency.

[0041] See also Figure 1 and Figure 4 The four corners of the top surface of the hardware die-casting 1 are fixedly connected with connecting columns 16, and the top of the connecting column 16 is threadedly connected with a fastening nut 18. The top surface of the hardware die-casting mounting plate 3 is provided with rectangular connecting holes 17, and the top of the connecting column 16 passes through the inner wall of the connecting hole 17.

[0042] The metal die-casting 1 is fixedly mounted inside the metal die-casting mounting plate 3 by tightening the nut 18 for threaded connection.

[0043] See also Figure 1 and Figure 2 A dust screen 15 is fixedly connected to the inner wall of the air outlet 14 .

[0044] It can prevent dust from entering the inside of the protective cover.

[0045] During operation, the metal die-casting 1 generates heat, which is transferred to the heat sink 2 fixed on its surface by conduction. The first heat dissipation tube 4 fixedly installed on the heat dissipation top surface of the heat sink 2 receives the heat from the heat sink 2. The first heat dissipation tube 4 is connected to the second heat dissipation tube 5 above it through a symmetrically arranged circulation conveying tube 6. The heat is transferred from the first heat dissipation tube 4 to the second heat dissipation tube 5 through the circulation conveying tube 6. The circulating conveying pipe 6 transports the cooling medium in the cooling box 7 to the first heat dissipation pipe 4 and the second heat dissipation pipe 5. The cooling medium absorbs heat during the flow process, realizes heat exchange, and reduces the temperature of the hardware die-casting. At the same time, the blowing fan 13 is started, and air enters from the vent 12. Since the top surface of the second heat dissipation pipe 5 is fixedly connected with equidistantly distributed S-shaped fins 10, and the gap direction of the fins 10 is consistent with the outlet direction of the blowing fan 13, the air flows along the gap of the fins 10. When passing through the fins 10, it exchanges heat with the fins 10 and takes away the heat on the fins 10. The air continuously absorbs heat during the flow process, and then is discharged from the air outlet 14 on the side of the protective cover 11 away from the blowing fan 13. The dust screen 15 on the inner wall of the air outlet 14 can prevent dust from entering the inside of the protective cover.

[0046] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
