Description

Technical Field

[0001] The utility model belongs to the technical field of electronic products, and in particular relates to a radiator adopting a novel fan arrangement scheme. Background Art

[0002] As the functions of chips become more powerful, the heat generated by the chips is also getting higher and higher. Therefore, fans are usually set up to blow room temperature air to the heat sink fins to achieve heat dissipation.

[0003] At present, common chip air-cooled radiators are mainly classified into single-tower and multi-tower types according to the number of cooling fin groups. For single-tower radiators and multi-tower radiators, multiple fans can usually be set up to accelerate the exchange rate between the air between the fins and the outside room temperature air through the fans, so as to achieve the effect of improving the heat dissipation efficiency. However, the fans in existing radiators often have the same blade structure and the same direction of rotation. For example, in a double-tower radiator, when the room temperature air is blown through the first cooling fin group by the first fan, because the bending direction of the second fan blade is the same as the bending direction of the first fan blade, and the same direction of rotation, more air contacts the non-working surface of the second fan, which easily causes air loss. This limits the heat dissipation efficiency of the radiator to a certain extent. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] In the description of the present invention, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] See also Figure 1-Figure 8 In an embodiment of the present application, a radiator adopting a novel fan arrangement scheme is provided, including: at least two fan assemblies 4 arranged in parallel, the rotation directions of adjacent fan assemblies 4 are opposite; at least one heat dissipation fin group 3, the heat dissipation fin group 3 and the fan assemblies 4 are arranged in parallel and alternately, and are used for heat dissipation through the fan assemblies 4. In an embodiment of the present application, by arranging the fan assemblies and the heat dissipation fin groups alternately in parallel, and the rotation directions of adjacent fan assemblies are opposite, when room temperature air is blown through the first heat dissipation fin group through the first fan assembly, because the blades of the second fan assembly turn in the opposite direction to the blades of the first fan assembly, more air can directly contact the working surface of the second fan assembly, so that more air volume can pass through the second fan assembly, and more wind force that can dissipate heat to the heat dissipation fin group is generated under the action of the second fan assembly, so as to improve the heat dissipation efficiency.

[0036] Among them, the rotation directions of adjacent fan assemblies are opposite. Taking two fan assemblies 4 as an example, the rotation direction of the first fan assembly 4 is counterclockwise, and the rotation direction of the second fan assembly 4 can be clockwise. If the rotation direction of the first fan assembly 4 is clockwise, the rotation direction of the second fan assembly 4 can be counterclockwise.

[0037] In one embodiment of the present application, the number of the fan assemblies 1 is the same as the number of the heat sink fin groups 2. Specifically, since the fan assemblies 4 and the heat sink fin groups 3 can be arranged alternately and in parallel, for example, taking two fan assemblies 4 and two heat sink fin groups 3 as an example, a fan assembly 4 can be set first, then a heat sink fin group 3 can be set, and then another fan assembly 4 can be set, and then a heat sink fin group 3 can be set. The fan assemblies 4 can blow air toward the heat sink fin group 3 set behind them, for example, the first fan assembly 4 blows air to the first heat sink fin group 3, and the second fan assembly 4 blows air to the second heat sink fin group 3. Since the rotation directions of adjacent fan assemblies are opposite, when the room temperature air blows through the first heat sink fin group 3 through the first fan assembly 4, since the blades of the second fan assembly 4 and the blades of the first fan assembly 4 turn in the opposite direction, more air can directly contact the working surface of the second fan assembly 4, so that more air volume can be blown to the second heat sink fin group 3 through the second fan assembly 4 to improve the heat dissipation efficiency.

[0038] It should be noted that, when there are multiple fan assemblies 4 and multiple heat sink fin groups 3, they can be arranged in an alternating manner in sequence according to the above method until the arrangement is completed.

[0039] In one embodiment of the present application, the number of the fan assemblies 1 is different from the number of the heat sink fin group 2. Specifically, the number of the fan assemblies 4 is equal to the number of the heat sink fin group 3 + 1. For example, the number of the fan assemblies 4 is 2, the number of the heat sink fin group 3 is 1, the number of the fan assemblies 4 is 5, the number of the heat sink fin group 3 is 4, and so on. Taking 2 fan assemblies 4 and 1 heat sink fin group 3 as an example, the 2 fan assemblies 4 are arranged in parallel, and the heat sink fin group 3 is arranged between the two, arranged in a queue, and both the 2 fan assemblies 4 can dissipate heat from the heat sink fin group 3 to speed up the air flow rate and improve the heat dissipation efficiency.

[0040] See also Figure 8 In one embodiment of the present application, the heat sink includes: a base 1, on which a plurality of slots 11 are arranged in parallel; a plurality of heat pipes 2 are sequentially embedded in the slots 11 to be engaged with the base 1, and the heat pipes 2 are used to transfer heat from a heat source to a heat dissipation fin group 3. The heat pipes 2 can be fixed by the base 1 to avoid movement under external force, thereby preventing unnecessary risks.

[0041] See also Figure 6The heat dissipation fin group 3 includes: a plurality of heat dissipation fins 32 which are sleeved on the heat pipe 2 and arranged in parallel along the length direction of the heat pipe 2, and a heat dissipation gap 33 is set between adjacent heat dissipation fins 32. Specifically, the heat dissipation fin 32 can be provided with a plurality of through holes 321, and a hole-turning structure 322 is arranged around the through holes. When assembling, the heat dissipation fin 32 can be sleeved on the heat pipe 2 through the through holes 321. At this time, the hole-turning structure 322 can be used to block the upper heat dissipation fin 32 to avoid direct contact between the upper and lower heat dissipation fins 32, thereby forming the heat dissipation gap 33, so that the air volume generated by the fan assembly 4 can flow through the heat dissipation gap 32, so as to increase the contact area between the air volume and the heat dissipation fin 32, thereby improving the heat dissipation efficiency.

[0042] In an embodiment of the present application, the fan assembly 4 is connected to the vertical surface of the edge of the adjacent heat sink fin group 3 through the connection structure 5. Specifically, the two sides of the fan assembly 4 can be connected to the connection structure 5 respectively, and the other end of the connection structure can be connected to the vertical surface of the edge of the heat sink fin group 3, so that the fan assembly 4 and the heat sink fin group 3 are assembled together without affecting the shielding of the heat sink surface of the heat sink fin group 3, which is conducive to heat dissipation of the heat sink fin group 3, and the overall structure is more compact.

[0043] The fan assembly 4 and the heat sink fin assembly 3 may be detachably connected, for example, by snap-fitting, threading, etc.

[0044] In one embodiment of the present application, the fan assembly 4 can be connected to the vertical surface of the edge of the heat dissipation fin group 3 located in front of it through a connecting structure 5, or can be connected to the vertical surface of the edge of the heat dissipation fin group 3 located behind it through a connecting structure 5, or can be connected to the vertical surfaces of the edge of the heat dissipation fin group 3 located in front of it and behind it through a connecting structure 5.

[0045] See also Figure 4 , Figure 5 In one embodiment of the present application, the connection structure 5 includes: a first connection portion 51 connected to a vertical surface of the edge of the heat dissipation fin group 3; second connection portions 52 respectively arranged on both sides of the first connection portion 51 for connecting to the fan assembly 4, and a buckle 521 is arranged at a free end of the second connection portion 52. Specifically, a mounting hole 411 is arranged on the fan assembly 4, and the buckle 521 passes through the mounting hole 411 and is blocked at the edge of the mounting hole 411 to achieve the connection between the first connection portion 51 and the fan assembly 4.

[0046] The connection structure 5 may be a wire buckle.

[0047] In an embodiment of the present application, the first connection portion 51 includes: oppositely arranged clamping portions 511, the clamping portions 511 being used to clamp with the heat dissipation fin group 3; and a prying structure 512 arranged between the clamping portions 511, the prying structure 512 being arranged obliquely away from the clamping direction of the clamping portion 511. A clamping groove 31 for clamping with the clamping portion 511 is arranged on a vertical surface of the edge of the heat dissipation fin group 3, and the clamping groove 31 is arranged obliquely toward a side close to the connection structure 5.

[0048] Specifically, the prying structure 512 can be made of an elastic material, such as a metal material. After the clamping is achieved, the prying structure 512 will apply pressure to the edge of the clamping slot 31 during the process of restoring to the original state due to the elastic deformation, thereby fixing the clamping portion 511 to prevent the clamping portion 511 from being separated from the heat sink fin group 3. When the fan assembly 4 needs to be separated from the heat sink fin group 3, pressure can be applied to the prying structure 512 to cause elastic deformation to pry the clamping portion 511 and separate it from the clamping slot 512 to achieve disassembly.

[0049] See also Figure 4 In one embodiment of the present application, the fan assembly 4 comprises: a mounting frame 41, on which a plurality of mounting holes 411 may be provided; and a fan blade structure 42 provided on the mounting frame 41 for generating wind force by rotation. The fan blade structure 42 may comprise a plurality of fan blades. When the fan is rotating, the air particles in the volume where the blades are located may be pushed downward, resulting in a continuous decrease in the air pressure at the air inlet of this area and a continuous increase in the air pressure at the air outlet, causing an increase in the axial air pressure of the entire fan blade area; because the air pressure outside the air inlet is greater than the air pressure at the air inlet, the external air is supplemented, and the supplemented air is also transported to the high-pressure area by the blades, causing a further decrease in the air pressure at the air inlet, attracting more air to supplement this low-pressure area, and so on. The cycle continues until the amount of supplemented air is equal to the amount of air delivered by the fan industry and equal to the amount of air gushing out of the air outlet, and a dynamic balance is achieved, thereby achieving heat dissipation treatment of the heat dissipation fin group.

[0050] The fan blade structure 42 can be movably connected to the power output end of the rotary drive component, and its fan blades can be equidistantly arranged along the circumference of the power output end, and can rotate clockwise or counterclockwise under the drive of the rotary drive component.

[0051] Wherein, the rotation driving component can be a motor.

[0052] The airfoils of the blades in the blade structure 42 are the same or different. For example, the blade airfoils of the blade structure 42 are the same, such as all are forward-swept wings, that is, the blade airfoils are bent forward along the direction of fan operation. Alternatively, the blades of the blade structure 42 can also be set to be different, for example, the blade airfoils of the blade structures 42 of adjacent fan assemblies 4 are different.

[0053] In the embodiments of the present application, Figure 7 As shown, the fan blade can be divided into a working surface A and a non-working surface B. The working surface refers to the fan blade surface in the same direction as the air flow direction, and the non-working surface refers to the fan blade surface in the opposite direction to the air flow direction. It can be understood that the working surface of the fan blade of the fan assembly 4 can be set in the direction where the heat sink fin group 3 is located. For example, for a scenario where the number of fan assemblies 4 and heat sink fin group 3 is the same, the working surfaces of all fan assemblies 4 can face the same direction, but the rotation directions of adjacent fan assemblies 4 are different.

[0054] In an embodiment of the present application, fan assemblies and heat sink fin groups are alternately arranged in parallel, and the rotation directions of adjacent fan assemblies are opposite. Taking a double-tower radiator as an example, fan assemblies and heat sink fin groups are alternately arranged in parallel, and the rotation directions of adjacent fan assemblies are opposite. When room temperature air passes through the first heat sink fin group through the first fan assembly, since the blades of the second fan assembly turn in opposite directions to the blades of the first fan assembly, more air can directly contact the working surface of the second fan assembly, thereby allowing more air volume to pass through the second fan assembly, and under the action of the second fan assembly, more wind force is generated to dissipate heat to the heat sink fin group, thereby improving the heat dissipation efficiency.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
