Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and more specifically, to a stacked nested cold-forged heat sink. Background Technology

[0002] Stacked nested cold-forged radiators are a special structural type of cold-forged radiators. These radiators typically consist of multiple heat dissipation components arranged in a stacked, nested manner. For example, they may have multiple layers of heat dissipation fins, one nested inside the other, or heat dissipation structures of different shapes nested together, forming a complex but orderly heat dissipation system. This design can significantly increase the heat dissipation area and improve heat dissipation efficiency within a limited space.

[0003] Existing cold-forged heat sinks use direct heat exchange, but the simple, linear fin structure results in a narrow heat exchange area. The direct flow of fluid within the fins easily creates a single internal flow field, leading to low heat exchange efficiency and quality on the inner side of the flow field. Furthermore, the complex fin structure generates noise during fluid flow, making it inconvenient to use. Therefore, we propose a stacked, nested cold-forged heat sink. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a stacked nested cold-forged radiator to solve the technical problems of small heat exchange area and low heat exchange efficiency and quality of single flow field in current heat dissipation devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stacked nested cold-forged radiator, including an outer frame, a radiator body, and a coolant box. A fixing cover is fixed to the lower opening of the outer frame by screws. The radiator body is slidably installed inside the outer frame. A liquid flow mechanism is installed inside the radiator body. A flow guiding mechanism is provided on both sides of the radiator body. There are two coolant boxes, and the two coolant boxes are respectively installed in the upper and lower openings of the radiator body. The coolant boxes are in contact with the liquid flow mechanism. Fixing blocks are fixed at both ends of one side of the radiator body.

[0006] In use, the corresponding pipes are connected, and high-temperature liquid is introduced into the inlet box through the inlet pipe, then flows into the cavity of the corresponding fin strip, returns through the return box, and then enters the cavity of another fin strip. After multiple cycles of flow, it is discharged from the fin strip. Coolant enters the first side box through the supply port, passes through the guide box and connecting pipe into the cold liquid box, then enters the second side box and is discharged from the outlet. The plug-in structure design protects the radiator body with the outer frame and facilitates disassembly and maintenance. At the same time, the wavy strip fins can increase the heat exchange area and ensure heat exchange quality. Meanwhile, the wave-like structure disrupts the relatively stable flow of fluid as it flows over the wavy fins. As the fluid flows along the undulating surface, it constantly changes its direction and speed, creating a complex flow field. This ensures heat exchange quality. The flow guide box is positioned and clamped by the notch on the coolant box, and then the clamping cavity holds and fits the fins. After the two coolant boxes are molded together, the heat exchange fins are completely covered, ensuring heat exchange quality and improving protection performance, preventing deformation and damage to the relatively fragile copper fins caused by external impacts.

[0007] Preferably, the upper end of the outer frame is provided with a port, and both sides of the outer frame are provided with external interfaces.

[0008] Preferably, the liquid flow mechanism consists of a return box, a fin strip, and a liquid inlet box. The return box and the liquid inlet box are respectively installed in the openings on the front and rear end faces of the radiator body, and the return box and the liquid inlet box are connected by the fin strip. The outer ends of the liquid inlet box are respectively connected by an inlet pipe and a drain pipe.

[0009] Preferably, there are six fin strips in total, and the six fin strips are equidistantly distributed. The fin strips are wavy and have cavities inside.

[0010] Preferably, the flow guiding mechanism is composed of a first side box and a second side box, and the first side box and the second side box are respectively installed in the openings on both sides of the radiator body. The inner side of the first side box and the second side box are provided with flow guiding boxes, the outer side of the first side box is provided with a liquid supply port, and the outer side of the second side box is provided with a liquid outlet.

[0011] Preferably, both the flow guide box and the fixing block are shark tooth shaped, the coolant box is fixed to the fixing block by bolts, and the upper and lower sides of the flow guide box are provided with insertion ports.

[0012] Preferably, both ends of the outer side of the coolant box are provided with notches, and a connecting pipe is installed through the corresponding notch. The connecting pipe is inserted into the socket of the corresponding flow guide box. The coolant box is provided with clamping cavities at equal intervals, and the fins are inserted into the clamping cavities.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs finned strips to connect corresponding pipes. High-temperature liquid is introduced into the inlet box through the inlet pipe, then flows into the cavity of the corresponding finned strip, returns through the return box, and then enters the cavity of another finned strip. After multiple repeated flows, it is discharged from the finned strip. Coolant enters the first side box through the supply port, enters the cold liquid box through the guide box and the connecting pipe, and then enters the second side box before being discharged from the outlet. The plug-in structure design protects the radiator body with the outer frame and facilitates disassembly and maintenance. At the same time, the wavy strip fins can increase the heat exchange area and ensure the heat exchange quality. In addition, the wavy structure can disrupt the originally relatively stable flow state of the fluid when it flows through the wavy finned strip. As the fluid flows along the undulating surface of the wavy strip, it will continuously change its flow direction and speed, generating a complex flow field, which ensures the heat exchange quality.

[0015] 2. This utility model also designs a cold liquid box, which uses a notch on the cold liquid box to clamp and position the flow guide box part, and then clamps and fits the fin strip in the clamping cavity. After the two cold liquid boxes are molded together, the heat exchange fin strip is completely covered, which ensures the quality of heat exchange and improves the protection performance, avoiding deformation and damage to the relatively fragile copper fin strip part caused by external force.

The radiator body 2 is composed of a return box 501, fin strips 502, and an inlet box 503.

An inlet pipe 504 and a drain pipe 505 are respectively installed through the outer ends of the inlet box 503. There are six fin strips 502 in total, which are equidistantly distributed and have a wavy shape. The fin strip 502 has a cavity for connecting the corresponding pipes. High-temperature liquid is introduced into the inlet box 503 through the inlet pipe 504, and then flows into the cavity of the corresponding fin strip 502. After passing through the return box 501, it flows back into the cavity of another fin strip 502. After multiple repeated flows, it is discharged from the fin strip 502. The coolant enters the first side box 402 through the supply port 401, passes through the guide box 403 and the connecting pipe 303 into the cold liquid box 3, and then enters the second side box 404 before being discharged from the outlet 405. The plug-in structure design protects the radiator body 2 with the outer frame 1 and facilitates disassembly and maintenance. At the same time, the wavy strip fins can increase the heat exchange area and ensure the heat exchange quality. The wavy structure can also disrupt the originally relatively stable flow state of the fluid when it flows through the wavy fin strip 502. As the fluid flows along the undulating surface of the wavy shape, it will continuously change its flow direction and speed, generating a complex flow field, which ensures the heat exchange quality.

A liquid supply port 401 is opened on the outer side of the first side box 402, and a liquid outlet 405 is opened on the outer side of the second side box 404. The flow guiding box 403 and the fixing block 201 are both shark-tooth shaped. The coolant box 3 is fixed to the fixing block 201 by bolts. The upper and lower sides of the corresponding flow guide box 403 are provided with insertion ports. The outer ends of the coolant box 3 are provided with recesses 302, and the connecting pipe 303 is installed through the corresponding recesses 302. The connecting pipe 303 is inserted into the insertion port of the corresponding flow guide box 403.

The flow guide box 403 is clamped and positioned by the recesses 302 on the coolant box 3, and then the clamping cavity 301 clamps and fits the fin strip 502. After the two coolant boxes 3 are molded together, the heat exchange fin strip 502 is completely covered to ensure the quality of heat exchange. At the same time, it can improve the protection performance and avoid deformation and damage to the relatively fragile copper fin strip 502 caused by external impact.

[0026] Working Principle: This embodiment provides a stacked nested cold-forged radiator. In use, the corresponding pipes are connected. High-temperature liquid is introduced into the inlet box 503 through the inlet pipe 504, and then flows into the cavity of the corresponding fin strip 502. After passing through the return box 501, it flows back into the cavity of another fin strip 502. After multiple repeated flows, it is discharged from the fin strip 502. The coolant enters the first side box 402 through the supply port 401, passes through the guide box 403 and the connecting pipe 303 into the cold liquid box 3, and then enters the second side box 404 before being discharged from the outlet 405. The guide box 403 is clamped and positioned by the notch 302 on the cold liquid box 3, and then the clamping cavity 301 clamps and fits the fin strip 502.
