Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a partitioned radiator. Background Technology

[0002] Heat pipe radiators are high-efficiency heat dissipation devices. Existing heat pipe radiators have a heat pipe section that is a single unit, with the temperature distributed axially between the evaporation and condensation sections. When the heat dissipation space is small, the use of existing heat pipe radiators is limited. Therefore, how to achieve heat dissipation in a small space has become an urgent problem to be solved in this field. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a partitioned radiator that separates the condensation and heat dissipation parts by connecting a first heat pipe and a second heat pipe. This design features a compact structure, small footprint, and greater flexibility in space utilization. Through the combination of the first heat pipe, the second heat pipe, the first capillary structure, and the second capillary structure, the radiator achieves rapid heat dissipation with high heat dissipation power, meeting the heat dissipation needs when there is insufficient space.

[0004] To achieve the above objectives, this utility model provides a partitioned heat sink, comprising a metal plate, multiple heat pipes, and a heat sink block. The heat pipes include a first heat pipe and a second heat pipe, which are connected in an L-shape. The first heat pipe is fixedly connected to the metal plate, and the second heat pipe is fixedly connected to the heat sink block. The heat sink block is provided with multiple heat dissipation fins.

The first heat pipe has a first capillary structure, and the second heat pipe has a second capillary structure. The first capillary structure and the second capillary structure are connected.

[0012] The beneficial effects of this utility model are as follows: The partitioned radiator provided by this utility model is mainly used to dissipate heat from the heat source when the heat dissipation space is insufficient. By setting the heat pipe into two parts, a first heat pipe and a second heat pipe, the evaporation chamber in the first heat pipe is used for the evaporation of the high-temperature working medium, and the heat is transferred to the condensation chamber of the second heat pipe. The condensation chamber condenses the working medium, reducing its temperature.

[0019] Example: Please refer to Figures 1 to 3 ,

[0020] A partitioned heat sink includes a metal plate 1, multiple heat pipes 2, and a heat sink 3. The heat pipes 2 include a first heat pipe 21 and a second heat pipe 22, which are connected in an L-shape. The first heat pipe 21 is fixedly connected to the metal plate 1, and the second heat pipe 22 is fixedly connected to the heat sink 3. The heat sink 3 is provided with multiple heat dissipation fins 4.

[0021] The first heat pipe 21 has an evaporation chamber 23, and the second heat pipe 22 has a condensation chamber 24. The evaporation chamber 23 and the condensation chamber 24 are connected. The first heat pipe 21 has a first capillary structure 51, and the second heat pipe 22 has a second capillary structure 52. The first capillary structure 51 and the second capillary structure 52 are connected. The evaporation chamber 23 and the condensation chamber 24 contain working media.

[0022] The lower part of the metal plate 1 is in contact with the heat source, and multiple heat pipes 2 are connected to the upper part of the metal plate 1. A working medium is provided inside the evaporation chamber 23. In the non-working state, the working medium is liquid. In the working state, in this embodiment, the heat source is the chip 6. The metal plate 1 is in contact with the heat source, and the heat emitted by the chip 6 during operation is transferred to the multiple heat pipes 2 through the metal plate 1. Due to the negative pressure inside the evaporation chamber 23, the extremely low temperature causes the liquid working medium inside to vaporize into a gaseous state. The gaseous working medium carries heat within the evaporation chamber 23 towards the lower-temperature second heat pipe 22, where the higher-temperature gaseous medium... When the working medium encounters the cooler condensation chamber 24, it condenses into a liquid working medium. This liquid then flows back along the second capillary structure 52 to the first capillary structure 51, and finally back to the first heat pipe 21. This cycle repeats continuously, transferring heat from the chip 6. The heat is then diffused away by the heat sink 3 and multiple heat sinks 4, ultimately transferring the heat from the chip 6 to achieve a cooling effect. The connection between the first heat pipe 21 and the second heat pipe 22 separates the condensation and heat dissipation sections, resulting in a compact structure that occupies little space and offers greater flexibility in space utilization.

[0023] The heat pipe 2 is configured as a flat type, and there is a gap between adjacent heat pipes 2. The flat type can increase the contact area between the first heat pipe 21 and the metal plate 1, thereby increasing the amount of heat transferred per unit time and improving the heat dissipation power of the radiator.

[0024] A graphite heat dissipation film 11 is provided on the upper end of the metal plate 1. The graphite heat dissipation film 11 has adhesive on both sides and is attached to the metal plate 1. The other side is used to attach the first heat pipe 21. The graphite heat dissipation film 11 can reduce the gap between the first heat pipe 21 and the metal plate 1, thereby reducing the thermal resistance between them and improving the heat dissipation power of the radiator.

[0025] The lower end of the metal plate 1 is provided with a heat-conducting area 12, and a heat-conducting gel is provided on the heat-conducting area 12. The heat-conducting gel can reduce the gap between the chip 6 and the metal plate 1, thereby reducing the thermal resistance between the chip 6 and the metal plate 1 and improving the heat dissipation power of the heat sink.

[0026] Multiple groove partitions 13 are provided above the metal plate 1. The first heat pipe 21 is fixedly connected in the groove partition 13. The inner wall of the groove partition 13 is coated with a graphite heat dissipation film 11. The graphite heat dissipation film 11 can reduce the gap between the first heat pipe 21 and the metal plate 1, thereby reducing the thermal resistance between them and improving the heat dissipation power of the radiator.

[0027] The radiator also includes a fixing bracket, which includes a fixing plate 71 and four fixing support plates 72. The fixing support plates 72 are located at four opposite positions of the fixing plate 71. The fixing support plates 72 are provided with threaded holes. In this embodiment, the four fixing support plates 72 are located on the four sides of the fixing plate 71. According to the actual space requirements, other distribution patterns are also possible. The fixing plate 71 and the four fixing support plates 72 form an embedded space for fixing the metal plate 1 in the heat dissipation space reserved for the heat source.

[0028] Multiple first heat pipes 21 are parallel to each other, multiple second heat pipes 22 are parallel to each other, and multiple heat sinks 4 are parallel to each other. Other distribution patterns are also possible depending on the actual space requirements.

[0029] In summary, the partitioned radiator provided by this utility model is mainly used to dissipate heat from a heat source when the space reserved for heat dissipation is insufficient. By setting the heat pipe into two parts, a first heat pipe and a second heat pipe, the evaporation chamber in the first heat pipe is used for the evaporation of the high-temperature working medium, which transfers the heat to the condensation chamber of the second heat pipe. The condensation chamber condenses the working medium, reducing its temperature. The condensed working medium returns to the first heat pipe along the second capillary structure and the first capillary structure. The second heat pipe transfers the heat to the heat sink, and the heat sink diffuses the heat away through the heat sink fins. The overall radiator occupies a small space, and the space for condensation and heat dissipation is transferred out through the connection of the first and second heat pipes. The structure is compact, occupies little space, and is more flexible in terms of space utilization. Through the combination of the first heat pipe, the second heat pipe, the first capillary structure, and the second capillary structure, the radiator achieves rapid heat dissipation and high heat dissipation power.

[0030] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
