Description

Technical Field

[0001] The utility model relates to the field of heat dissipation, in particular to a heat dissipation module. Background Art

[0002] With the rapid development of electronic technology, the heat-generating components such as chips, circuit boards, processors, etc. in various electronic devices are gradually moving towards high performance and thinness, which greatly increases the heat energy generated by each heat-generating component. Therefore, ordinary radiators have gradually been unable to meet the heat dissipation needs of each heat-generating component. Therefore, extended volume air cooling (EVAC) radiators have been developed in air-cooled radiators. They mainly connect traditional heat-absorbing components and heat-dissipating components through heat pipes, so that the heat-absorbing components and the heat-dissipating components are thermally coupled, thereby expanding the overall air-cooled heat dissipation volume to improve the heat dissipation effect.

[0003] In recent years, in response to the gradual increase in the heat energy generated by various heat-generating components, the heat-absorbing components and heat-dissipating components of EVAC radiators have also increased in size and weight accordingly, so as to achieve a better heat dissipation effect to meet the heat dissipation needs of various heat-generating components. However, since the heat-absorbing components and the heat-dissipating components are only connected by heat pipes, when users or maintenance personnel are moving, repairing, or loading and unloading EVAC radiators, the heat pipes are often excessively pulled and bent due to the excessive weight of the heat-absorbing components or the heat-dissipating components themselves, which irreversibly affects the heat conduction effect of the heat pipes, and further affects the heat dissipation effect of the EVAC radiator.

[0004] In view of this, the inventor has focused on the shortcomings of the above-mentioned prior art, conducted intensive research and applied theoretical knowledge to try his best to solve the above-mentioned problems, which has become the goal of the inventor's improvement.

[0015] In an embodiment of the present invention, each pivoting portion is arch-shaped, arc-shaped or crescent-shaped.

[0016] The heat dissipation module of the utility model uses a movable handle assembly to bridge the heat absorption component and the heat dissipation component, so that the user can grasp the handle body in the upright position when transferring, repairing or loading and unloading the heat dissipation module, thereby driving the heat absorption component and the heat dissipation component through the movable handle assembly, thereby preventing the heat pipe from being excessively bent and deformed due to direct force, and when the movable handle assembly is not needed, the handle body can be pivoted to a flat position to reduce the occupied space.

[0046] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit the present invention.

[0047] The utility model provides a heat dissipation module for dissipating heat from a heat source (not shown). Figures 1 to 5 As shown, the heat dissipation module of the present invention mainly includes at least one heat absorbing component 10, at least one heat dissipation component 20, at least one heat pipe 30 and at least one movable handle group 40. It should be noted that the heat dissipation module shown in this embodiment is an extended volume air cooling (EVAC) radiator, but the present invention is not limited thereto, and the heat dissipation module of the present invention can also be a liquid cooling radiator or other forms of radiators.

[0048] The heat absorbing component 10 is attached to the top of the heat source to absorb the heat energy generated by the heat source. The heat absorbing component 10 is arranged opposite to the heat dissipating component 20. In the present embodiment, the heat absorbing component 10 and the heat dissipating component 20 are arranged opposite to each other left and right and are roughly parallel, but in other embodiments, they can also be arranged opposite to each other up and down or arranged diagonally in a staggered manner, and the present invention does not impose many restrictions on this. In addition, the heat absorbing component 10 in the present embodiment includes a vapor chamber 11 and a heat sink fin group 12 (heat sink) arranged on the vapor chamber 11, and the heat sink fin group 20 includes another pair of heat sink fin groups 21, but the present invention is not limited to the above, for example, the heat absorbing component 10 can also replace the vapor chamber 11 with a thermal pad or a thermoelectric cooling (TEC) chip.

[0049] The heat pipe 30 connects the heat absorbing component 10 and the heat dissipating component 20, so that the heat absorbing component 10 is thermally coupled to the heat dissipating component 20, and the heat energy absorbed by the heat absorbing component 10 can be transferred to the heat dissipating component 20 for heat dissipation. In the present embodiment, the heat pipe 30 is a heat pipe, but the present invention is not limited thereto. For example, the heat pipe 30 can also be a bundle structure formed by winding metal wires, or a coil structure formed by winding metal meshes. In addition, since the heat absorbing component 10 and the heat dissipating component 20 in the present embodiment are arranged opposite to each other and are roughly parallel, the heat pipe 30 is roughly horizontally connected between the heat absorbing component 10 and the heat dissipating component 20. In the present embodiment, the number of heat pipes 30 is multiple and they are arranged in sequence and parallel between the heat absorbing component 10 and the heat dissipating component 20, so that the heat energy absorbed by the heat absorbing component 10 can be quickly transferred to the heat dissipating component 20, but the number of heat pipes 30 is not limited thereto.

[0050] The movable handle assembly 40 is connected across the heat absorbing component 10 and the heat dissipating component 20, and is located in the vicinity of the heat pipe 30. Specifically, the movable handle assembly 40 can be located near the periphery of the heat pipe 30. When the movable handle assembly 40 is located above the heat pipe 30, the space occupied by the movable handle assembly 40 can be further reduced, which is beneficial to the overall spatial configuration and the improvement of the structural strength and mobility of the heat dissipating module. Specifically, the movable handle assembly 40 includes a pair of fixing seats 41 and a handle body 42. Each fixing seat 41 is fixed to the heat absorbing component 10 and the heat dissipating component 20, respectively, and the two ends of the handle body 42 are respectively pivoted to each fixing seat 41 and can be rotated between a horizontal position P1 and an upright position P2. When the handle body 42 in this embodiment is pivoted to the horizontal position P1, the handle body 42 is substantially parallel to the heat pipe 30, so that the handle body 42 is horizontally located above the heat pipe 30, thereby reducing the space occupied by the movable handle assembly 40 and facilitating the overall spatial configuration. When the handle body 42 of this embodiment is pivoted to the upright position P2, the handle body 42 is substantially perpendicular to the heat pipe 30, that is, the handle body 42 is upright above the heat pipe 30 and can be grasped by a user or maintenance personnel.

[0051] Thus, when the movable handle assembly 40 is not needed, the handle body 42 can be pivoted to the horizontal position P1 to save space. When the heat dissipation module of the present invention needs to be moved, repaired, or loaded and unloaded, the handle body 42 can be pivoted to the upright position P2 for the user or maintenance personnel to grasp, thereby preventing the heat pipe 30 from being excessively pulled and bent due to the excessive weight of the heat absorption component 10 or the heat dissipation component 20, thereby irreversibly affecting the heat conduction effect of the heat pipe 30, and further affecting the heat dissipation effect of the EVAC radiator.

[0052] In the present embodiment, there are two heat absorbing components 10, one heat dissipating component 20, and two movable handle groups 40 corresponding to the number of heat absorbing components 10. A plurality of heat pipes 30 and a movable handle group 40 are connected between each heat absorbing component 10 and the heat dissipating component 20. However, the present invention is not limited thereto. For example, three or more heat absorbing components 10 may be arranged relative to one heat dissipating component 20, one heat absorbing component 10 may be arranged relative to two or more heat dissipating components 20, or two or more heat absorbing components 10 may be arranged relative to two or more heat dissipating components 20. A person skilled in the art should be able to adjust the number of heat absorbing components 10, heat dissipating components 20 and movable handle groups 40 according to different requirements, and the number of movable handle groups 40 may also be adjusted accordingly according to the requirements of different configurations.

[0053] For further explanation, see Figures 2 to 4As shown, each fixing seat 41 includes a base plate 411 and at least one pivoting portion 412 disposed on the top of the base plate 411. In the present embodiment, the number of the pivoting portions 412 in each fixing seat 41 is two, but the present invention is not limited thereto. For example, the number of the pivoting portions 412 in each fixing seat 41 may also be one or more than three. The two ends of the handle body 42 are respectively pivoted to the pivoting portions 412 of each fixing seat 41. Specifically, in the present embodiment, the pivoting portions 412 of each fixing seat 41 of the movable handle assembly 40 are arranged on the same straight line, so that the handle body 42 can be pivoted relative to the pivoting portions 412 and rotate between the flat position P1 and the upright position P2. In the present embodiment, each pivoting portion 412 is arched, so that the end of the handle body 42 is pivoted therein, but the shape of the pivoting portion 412 is not limited thereto. For example, the pivoting portion 412 may also be in the form of an arc, a crescent or a pivot hole. In each fixing seat 41, the height of the pivoting portion 412 protruding from the base plate 411 is less than or equal to 5 mm, thereby effectively reducing the volume space of the movable handle assembly 40. Preferably, the height of the pivoting portion 412 protruding from the base plate 411 is less than or equal to 4 mm, and in this embodiment, the height of the pivoting portion 412 protruding from the base plate 411 is about 3.6 mm. Therefore, compared with a general movable handle (with a height of at least 5 mm), the movable handle assembly 40 of the utility model can effectively reduce the volume space and facilitate space configuration and light weight.

[0054] Furthermore, at least one substrate 411 extends with a baffle 413 extending toward the other substrate 411. In the substrate 411 having the baffle 413, a gap is formed between the baffle 413 and the pivoting portion 412 of the substrate 411. Thus, when the handle body 42 of the movable handle assembly 40 pivots to the horizontal position P1, due to the gap formed between the baffle 413 and the pivoting portion 412 of the substrate 411, the handle body 42 can abut against the top of the baffle 413 at each turning section described later, thereby preventing the handle body 42 from continuing to rotate and hitting the heat pipe 30 below. In this embodiment, each substrate 411 extends with a baffle 413 toward another opposite substrate 411, and each baffle 413 is located on the same side, but the utility model is not limited thereto, for example, each baffle 413 can also be located on different sides.

[0055] See also Figure 4As shown, the handle body 42 includes a pair of pivoting sections 421, a pair of turning sections 422 and a gripping section 423. The gripping section 423 is for the user or maintenance personnel to grip, and the two ends of the gripping section 423 are respectively connected to one end of each turning section 422. The other end of each turning section 422 is respectively connected to one end of each pivoting section 421. The other end of each pivoting section 421 is respectively pivoted in each pivoting portion 412 of each fixing seat 41. In this embodiment, each turning section 422 is vertically connected to the gripping section 423 and the corresponding pivoting section 421, but the utility model is not limited thereto. For example, each turning section 422 can also be obliquely connected to the gripping section 423 and the corresponding pivoting section 421, or each turning section 422 can be arc-shaped and connected to the gripping section 423 and the corresponding pivoting section 421.

[0056] To further explain, the movable handle assembly 40 in this embodiment further includes a pair of torsion springs 50. Each torsion spring 50 is respectively sleeved on each pivot section 421, so that the two ends of each torsion spring 50 elastically abut the corresponding pivot section 421 and the corresponding fixing seat 41. Specifically, the end of each pivot section 421 has a slot 4211, and each base plate 411 has a slot 414 protruding from the base plate 411 but lower than the pivot portion 412. The two ends of each torsion spring 50 are clamped in the corresponding slot 4211 and the corresponding slot 414. More specifically, one end of each torsion spring 50 is clamped in the slot 4211 at the end of the corresponding pivot section 421, and the other end of the torsion spring 50 is inserted into the slot 414 of the corresponding base plate 411. In this way, the torsion spring 50 can apply a torsion force to the handle body 42, so that the torsion spring 50 can pivot the handle body 42 to the flat position P1 through the torsion force, thereby preventing the handle body 42 from rotating when the heat dissipation module of the present invention is transferred or shaken, and the user or maintenance personnel only needs to apply an external force slightly greater than the torsion force to pivot the handle body 42 to the upright position P2 for use, and after use, the handle body 42 can be restored to the flat position P1 by the torsion force of the torsion spring 50.

[0057] It is worth noting that each fixing seat 41 in the present embodiment is respectively fixed to the heat absorbing component 10 and the heat dissipating component 20 by a plurality of bolts, but the arrangement of each fixing seat 41 is not limited thereto. For example, each fixing seat 41 can also be arranged on the heat absorbing component 10 and the heat dissipating component 20 by welding, clamping, buckling, bonding, fitting, pressing or screwing. In the present embodiment, the heat dissipating module further includes a pad 60 and a gasket 70 of different thicknesses. The pad 60 and the gasket 70 are respectively supported between the fixing seat 41 and the heat absorbing component 10 and between the fixing seat 41 and the heat dissipating component 20, so as to adjust the relative height between each fixing seat 41, thereby eliminating the height difference between the heat absorbing component 10 and the heat dissipating component 20, and further enabling the handle body 42 to be horizontally connected between the heat absorbing component 10 and the heat dissipating component 20.

[0058] It is particularly noted that the heat dissipation module of the present invention is not particularly limited to an extended volume air cooling (EVAC) radiator. For example, the heat dissipation module of the present invention can also be a liquid cooling radiator, that is, the heat absorption component 10 of the present invention can be a liquid cooling head, the heat dissipation component 20 can correspond to a liquid cooling row, and the heat pipe 30 is a liquid infusion tube with a heat conductive effect. Of course, the heat absorption component 10, the heat dissipation component 20 and the heat pipe 30 of the present invention are not limited to the above. A person with ordinary knowledge in the art should be able to select different forms of heat absorption components 10, heat dissipation components 20 and heat pipes 30 for combination.

[0059] The heat dissipation module of the present invention uses a movable handle assembly 40 to bridge the heat absorption component 10 and the heat dissipation component 20, so that the user can grasp the handle body 42 located at the upright position P2 when transferring, repairing or loading and unloading the heat dissipation module, thereby driving the heat absorption component 10 and the heat dissipation component 20 through the movable handle assembly 40, thereby preventing the heat pipe 30 from being excessively bent and deformed due to direct force, and when the movable handle assembly 40 is not needed, the handle body 42 can be pivoted to the horizontal position P1 to reduce the occupied space.

[0060] In summary, the above disclosure of the utility model is to enable those with ordinary knowledge in the field to clearly understand the technical content of the utility model and implement it accordingly, and is not intended to limit the scope of patent protection of the utility model. In addition, the utility model can of course have other unlisted embodiments. Without departing from the spirit and essence of the utility model, those familiar with the field should be able to evolve various corresponding changes and deformations based on the utility model, but these corresponding changes and deformations should all fall within the scope of protection of the patent applied for the utility model.
