Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to heat pipe radiators. Background Technology

[0002] Existing electronic components, such as chips, are highly integrated and operate at high power, generating significant and concentrated heat during operation. High temperatures not only cause instability and pose a safety hazard during operation but also accelerate the aging of component materials, reducing their lifespan. Therefore, for electronic components with concentrated heat, efficient heat dissipation devices such as heat pipe radiators are needed to quickly dissipate heat and reduce temperature rise.

[0003] A heat pipe radiator typically consists of a base, heat pipes, and a cooling module. The cooling module is spaced above the base and has multiple fins to increase the heat dissipation surface area. The heat pipes connect the base and the cooling module. During installation and use, the base absorbs heat upon contact with the heat source and conducts the heat to the heat pipes. The heat pipes then quickly conduct the heat to the cooling module, which dissipates the heat using its large surface area.

[0004] Among them, for some existing heat pipe radiators, the heat pipes are usually arranged in several spaced-out rows on the base, and their heat dissipation efficiency needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a bottom-row stacked heat pipe radiator that can improve heat dissipation efficiency.

[0006] To achieve the above objectives, a bottom-mounted stacked heat pipe radiator is provided, comprising a base plate, heat pipe assemblies, and a heat dissipation module. The heat pipe assemblies are disposed on the top of the base plate, and the heat dissipation module is connected to the heat pipe assemblies. Each heat pipe assembly includes a first heat pipe module and a second heat pipe module. Multiple first heat pipe modules are arranged sequentially, with the bottom sides of adjacent first heat pipe modules abutting each other. Each first heat pipe module includes a U-shaped first heat pipe component and a second heat pipe component. The width of the first heat pipe component is smaller than the width of the second heat pipe component. Two first heat pipe components are provided and disposed on opposite sides of the second heat pipe component, with the horizontal sections of the first heat pipe component abutting against the horizontal sections of the second heat pipe component. In each first heat pipe module, the vertical sections of the first and second heat pipe components are arranged alternately in the left-right direction. The second heat pipe module is located inside the first heat pipe modules, and the bottom of the second heat pipe module abuts against the top surfaces of the horizontal sections of the first and second heat pipe components.

[0008] According to the bottom-row stacked heat pipe radiator, the transverse section of the third heat pipe is perpendicular to the transverse sections of the first and second heat pipes.

[0009] According to the bottom-row stacked heat pipe radiator, the cross-sections of the transverse sections of the first heat pipe component, the second heat pipe component, and the third heat pipe component are all rectangular.

[0010] According to the aforementioned bottom-mounted stacked heat pipe radiator, the bottom plate is configured as a copper plate; or, the bottom plate is configured as a heat spreader; or, the bottom plate includes a fourth heat pipe component arranged in sequential contact.

[0031] Reference Figure 1-3 This utility model discloses a bottom-mounted stacked heat pipe radiator, comprising a base plate 10, a heat pipe assembly 20, and a heat dissipation module 30. The base plate 10 is used to contact a heat source for heat absorption. The heat pipe assembly 20 is disposed on the top of the base plate 10, and the heat dissipation module 30 is connected to the heat pipe assembly 20. The heat pipe assembly 20 includes a first heat pipe module 21 and a second heat pipe module 22. Multiple first heat pipe modules 21 are provided and arranged sequentially, with the bottom sides of adjacent first heat pipe modules 21 abutting against each other.

[0032] Each first heat pipe module 21 includes a U-shaped first heat pipe component 211 and a second heat pipe component 212, such that both the first heat pipe component 211 and the second heat pipe component 212 have a horizontal section and a vertical section. The horizontal sections of the first heat pipe component 211 and the second heat pipe component 212 abut against the top surface of the base plate 10 to absorb heat, and the vertical sections of the first heat pipe component 211 and the second heat pipe component 212 are connected to the heat dissipation module 30 for heat dissipation. The width of the first heat pipe component 211 is smaller than the width of the second heat pipe component 212. The first heat pipe component 211 is configured as two components and is located on both sides of the second heat pipe component 212. The horizontal section of the first heat pipe component 211 abuts against the side of the horizontal section of the second heat pipe component 212. The second heat pipe module 22 is located inside the first heat pipe module 21, and the bottom of the second heat pipe module 22 abuts against the top surface of the horizontal section of the first heat pipe component 211 and the second heat pipe component 212.

[0033] In each first heat pipe module 21, the vertical segments of the first heat pipe component 211 and the second heat pipe component 212 are arranged at intervals in the left-right direction. The upper parts of adjacent first heat pipe modules 21 can be spaced apart to evenly conduct heat to the heat dissipation module 30. Similarly, in each first heat pipe module 21, the vertical segments of its first heat pipe component 211 and the second heat pipe component 212 are arranged at intervals to avoid concentrated heat dissipation from the heat pipe components and to evenly conduct heat to the heat dissipation module 30.

[0034] In the above scheme, multiple first heat pipe modules 21 are arranged sequentially, with the bottom sides of adjacent first heat pipe modules 21 abutting each other, and the lateral sides of the first heat pipe component 211 and the second heat pipe component 212 of the first heat pipe module 21 abutting each other; the bottom of the second heat pipe module 22 abuts the top surface of the lateral section of the first heat pipe component 211 and the second heat pipe component 212. The first heat pipe module 21 provides the first layer of heat conduction, and the bottom of the second heat pipe module 22 is stacked on top of the bottom of the first heat pipe module 21 to provide the second layer of heat conduction. As such, a large number of heat pipe components can be arranged in the heat sink within a limited space, and the bottom of each heat pipe component can absorb heat, while the upper part can dissipate heat, improving the thermal conductivity of the heat pipe assembly 20, thereby improving the heat dissipation efficiency of the heat sink.

[0035] In this embodiment, the second heat pipe module 22 includes a plurality of third heat pipe components 221 arranged sequentially. Each third heat pipe component 221 has a horizontal section and a vertical section. The sides of the horizontal sections of adjacent third heat pipe components 221 abut against each other, and the vertical sections of each third heat pipe component 221 are spaced apart from each other. The horizontal section of the third heat pipe component 221 is also perpendicular to the horizontal sections of the first heat pipe component 211 and the second heat pipe component 212. The horizontal section of the third heat pipe component 221 can absorb heat and conduct heat to the heat dissipation module 30 through its vertical section; the horizontal section of the third heat pipe component 221 also has a temperature equalization function, which can evenly distribute heat among each first heat pipe module 21.

[0036] In this embodiment, the base plate 10 has three forms: first, the base plate 10 is a copper plate; second, the base plate 10 is a heat spreader; and third, the base plate 10 includes fourth heat pipes arranged in sequence, with the surfaces of adjacent fourth heat pipes in contact. All of these forms of the base plate 10 can quickly absorb heat from the heat source and distribute the heat evenly, so that the first heat pipe 211 and the second heat pipe 212 can fully and uniformly absorb heat.

[0037] In this embodiment, the cross-sections of each lateral segment of the first heat pipe 211, the second heat pipe 212, and the third heat pipe 221 are all rectangular, and the cross-sections of each vertical segment of the first heat pipe 211, the second heat pipe 212, and the third heat pipe 221 are all circular, in order to increase the contact area and reduce the thermal resistance.

[0038] In this embodiment, the heat dissipation module 30 includes heat sinks 31 arranged in sequence. The thickness of the heat sinks 31 is set to 0.3-0.5mm, and the gap thickness between adjacent heat sinks 31 is 1-3.5mm. The heat sinks 31 are sleeved on each vertical section, and the connection between the heat sinks 31 and each vertical section can be achieved by interference fit, riveting fit, soldering, or other methods.

[0039] Reference Figure 4-6 In another embodiment, the heat pipe radiator further includes a bottom frame 40 and a casing 50. The bottom frame 40 is fitted onto the outside of the bottom plate 10. The casing 50 includes side plates 51, bottom strips 52, and top strips 521. There are two side plates 51, which are respectively disposed on the left and right sides of the heat dissipation module 30. There are two bottom strips 52, which are arranged front and back. The two bottom strips 52 are respectively connected to the two side plates 51. The top strips 521 are also respectively connected to the two side plates 51. The distance between the two bottom strips 52 is not less than the width of the heat dissipation module 30 in the front and back direction. The two bottom strips 52 are connected to the top of the bottom frame 40. The casing 50 is provided with first mounting plates 53 on all four sides of the front and back sides. The first mounting plates 53 are provided with first through holes 531.

[0040] With this structure, a fan can be installed on the front side of the casing 50 (the first fastener passes through the fan and is inserted into the first through hole 531) to generate airflow through the heat dissipation module 30, and the side plate 51 can constrict the airflow, reduce airflow dissipation, and improve heat dissipation efficiency. The casing 50 is not fixed to the heat sink 31, and the casing 50 can be assembled by sliding it downwards, which is relatively convenient for assembly; during production, the casing 50 and other structures can be installed or not installed according to requirements, which facilitates production and allocation.

[0041] Furthermore, the enclosure 50 also includes a skirt 54, which has a vertical section 541 located outside the side plate 51 and a horizontal section 542 located below the side plate 51. The horizontal section 542 of the skirt 54 extends to abut against the outer wall of the bottom frame 40. Second mounting plates 55 are provided on both the front and rear sides of the skirt 54, and the second mounting plates 55 have second through holes 551 opposite to the first through hole 531. When installing the fan, the first fastener can also pass through the second through hole 551; additionally, the second fastener is passed through the rear first mounting plate 53 and the second mounting plate 55, detachably connecting the skirt 54 to the side plate 51. The skirt 54 can form a protective enclosure at the bottom, preventing airflow from escaping from the bottom of the radiator, improving airflow convergence, and allowing more airflow to pass through the bottom of the first heat pipe 211, the second heat pipe 212, and the third heat pipe 221, thereby improving heat dissipation efficiency. Skirt 54 can be separated from side plate 51 (skirt 54 is removed first during assembly, and skirt 54 and fan are installed after the enclosure 50 is fitted onto the heat dissipation module 30) to facilitate the assembly and disassembly of enclosure 50.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
