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 a few spaced-out rows on the base, and the number of heat pipes is relatively small, so the heat dissipation efficiency needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a heat pipe radiator with closely spaced heat transfer, which can improve heat dissipation efficiency.

[0006] To achieve the above objectives, a close-packed heat pipe radiator is provided, comprising: a base plate; a heat pipe assembly disposed on the top of the base plate, including a plurality of heat pipe modules arranged sequentially, with the bottom sides of adjacent heat pipe modules abutting against each other; and a heat dissipation module connected to the heat pipe assembly; wherein, the heat pipe module includes two first heat pipe components, two second heat pipe components, and two third heat pipe components arranged sequentially from front to back, the first and third heat pipe components being L-shaped, the second heat pipe components being U-shaped, the horizontal sections of the first, second, and third heat pipe components being arranged in abutting order, and the vertical sections being arranged at intervals from left to right and coplanar.

[0007] According to the heat pipe radiator with close-packed heat transfer, the transverse sections of the first heat pipe component, the second heat pipe component, and the third heat pipe component are all configured as square strips.

[0008] According to the heat pipe radiator with closely spaced heat transfer, the base plate is made of copper.

[0009] According to the heat pipe radiator with close-packed heat transfer, the base plate has a through mounting groove, and a heat spreader is installed in the mounting groove.

[0010] According to the heat pipe radiator with close-packed heat transfer, the base plate has a vertically penetrating mounting groove, and a plurality of fourth heat pipe components are arranged sequentially in the mounting groove. The fourth heat pipe components are perpendicular to the transverse sections of the first heat pipe component, the second heat pipe component, and the third heat pipe component.

[0011] According to the heat pipe radiator with close-packed heat transfer, it further includes a shell structure fitted onto the heat dissipation module. The shell structure includes: two side plates, which are respectively disposed on the left and right sides of the heat dissipation module. Each side plate has a first plate on its front and rear sides, and the first plate has a first through hole; two plate frames, which are respectively disposed on the front and rear sides of the heat dissipation module. The distance between the two plate frames is not less than the width of the heat dissipation module in the front-rear direction. Each plate frame has a second plate located inside the first plate, and the second plate has a second through hole opposite to the first through hole; the bottom of the plate frame is also connected to the top of the bottom plate.

[0012] According to the heat pipe radiator with close-packed heat transfer, a horizontal skirt is also provided at the bottom of the side plate, and the skirt extends to abut against the side wall of the bottom plate.

[0013] Beneficial effects: In the above scheme, the bottom sides of adjacent heat pipe modules abut against each other, and the transverse sections of the first heat pipe component, the second heat pipe component, and the third heat pipe component in the heat pipe module are arranged to abut against each other in sequence. This allows the radiator to have more heat pipe components in a limited space, and the bottom of each heat pipe component can absorb heat and the top can dissipate heat, which improves the thermal conductivity of the heat pipe assembly and thus improves the heat dissipation efficiency of the radiator.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Reference Figure 1-3 According to the first embodiment of this utility model, a heat pipe radiator with close-packed heat transfer includes a base plate 10, a heat pipe assembly 20 and a heat dissipation module 30. The heat pipe assembly 20 is disposed on the top of the base plate 10 and includes a plurality of heat pipe modules 21 arranged in sequence. The bottom sides of adjacent heat pipe modules 21 abut against each other. The heat dissipation module 30 is connected to the heat pipe assembly 20.

[0027] The heat pipe module 21 includes two first heat pipe components 211, two second heat pipe components 212, and two third heat pipe components 213 arranged sequentially in the front-to-back direction. The first heat pipe components 211 and the third heat pipe components 213 are L-shaped, and the second heat pipe components 212 are U-shaped, so that the first heat pipe components 211, the second heat pipe components 212, and the third heat pipe components 213 all have horizontal and vertical sections. The horizontal sections of the first heat pipe components 211, the second heat pipe components 212, and the third heat pipe components 213 are arranged in abutment to each other in sequence, and the vertical sections of the first heat pipe components 211, the second heat pipe components 212, and the third heat pipe components 213 are arranged at intervals in the left-to-right direction and are coplanar (that is, the axes of each vertical section in the heat pipe module 21 are located in the same plane, which is perpendicular to the front-to-back direction).

[0028] In the above scheme, the bottom sides of adjacent heat pipe modules 21 abut against each other, and the transverse sections of the first heat pipe component 211, the second heat pipe component 212 and the third heat pipe component 213 in the heat pipe module 21 are arranged to abut against each other in sequence, so that the heat sink can be equipped with more heat pipe components in a limited space, and the bottom of each heat pipe component can absorb heat and the top can dissipate heat, which improves the thermal conductivity of the heat pipe assembly 20, thereby improving the heat dissipation efficiency of the heat sink.

[0029] In addition, the vertical sections of the first heat pipe 211, the second heat pipe 212 and the third heat pipe 213 are arranged at intervals in the left and right direction and are coplanar. The vertical sections of each heat pipe module 21 are arranged at intervals to avoid concentrated heat dissipation of the heat pipes and to conduct heat evenly to the heat dissipation module 30.

[0030] In this embodiment, adjacent heat pipe modules 21 are centrally symmetrical. This ensures that the vertical sections are evenly distributed on both sides of the heat dissipation module 30, avoiding concentrated heat dissipation from the heat pipes and allowing heat to be evenly conducted to the heat dissipation module 30.

[0031] In this embodiment, the horizontal sections of the first heat pipe component 211, the second heat pipe component 212, and the third heat pipe component 213 are all square strips, and the vertical sections are cylindrical strips. Each heat pipe component can be formed by pressing and bending a heat pipe with a diameter of 6mm or 8mm into the aforementioned shape. This structure increases the contact area and reduces thermal resistance. Furthermore, the use of a round bottom and round top for the heat pipe components, rather than a completely square shape, reduces the manufacturing difficulty and cost of the heat pipes.

[0032] 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.

[0033] In this embodiment, the base plate 10 adopts the following form: the base plate 10 has a vertically penetrating mounting groove 11, and multiple fourth heat pipe components 12 are arranged sequentially in the mounting groove 11. The fourth heat pipe components 12 are perpendicular to the transverse sections of the first heat pipe component 211, the second heat pipe component 212, and the third heat pipe component 213. The fourth heat pipe components 12 are also configured as square strips. All of the above structural forms can quickly absorb heat from the heat source and distribute the heat evenly, so that each of the first heat pipe component 211, the second heat pipe component 212, and the third heat pipe component 213 absorbs heat uniformly.

[0034] In addition, the base plate 10 may also take the following forms: First, the base plate 10 is made entirely of copper plate; Second, the base plate 10 has a vertically penetrating mounting groove 11, and a heat equalization plate is installed in the mounting groove 11.

[0035] Reference Figure 4-5 The second embodiment of this utility model differs from the first embodiment in that: in the second embodiment, the heat pipe radiator further includes a shell structure 40 sleeved on the heat dissipation module 30.

[0036] Specifically, the enclosure structure 40 includes side plates 41 and frame plates 42. Two side plates 41 are provided on the left and right sides of the heat dissipation module 30, respectively. First plates 411 are provided at the top and bottom ends of both the front and rear sides of the side plates 41, and each first plate 411 has a first through hole 412. Two frame plates 42 are provided on the front and rear sides of the heat dissipation module 30, respectively. The distance between the two frame plates 42 is not less than the width of the heat dissipation module 30 in the front-rear direction. Each frame plate 42 has a second plate 421 located inside the first plate 411, and the second plate 421 has a second through hole 422 opposite to the first through hole 412. During assembly, first fasteners are inserted into the first through holes 412 and the second through holes 422, and the bottom of the frame plate 42 is connected to the top of the base plate 10 by second fasteners.

[0037] With this structure, a fan can be installed on the front side of the enclosure structure 40 (the first fastener passes through the fan and is inserted into the first through hole 412 and the second through hole 422) to generate airflow through the heat dissipation module 30. The side plate 41 can also constrict the airflow, reducing airflow loss and improving heat dissipation efficiency. The enclosure structure 40 is not fixed to the heat sink 31, and the enclosure structure 40 can be assembled by sliding it downwards, making assembly relatively convenient. During production, the enclosure structure 40 can be installed or not installed according to requirements, which facilitates production adjustments.

[0038] Reference Figure 6 The third embodiment of this utility model differs from the second embodiment in that: in the third embodiment, a horizontal skirt 413 is also provided at the bottom of the side plate 41, and the skirt 413 extends to abut against the side wall of the bottom plate 10.

[0039] The skirt 413 forms 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 213, thereby improving heat dissipation efficiency. Similarly, the enclosure structure 40 is detachably connected to the base plate 10, and the enclosure structure 40 can be installed or not during production as needed, facilitating production adjustments.

[0040] 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.
