Description

Radiator with enhanced stability

Technical Field

The utility model relates to the technical field of computer accessories, in particular to a radiator for enhancing stability.

Background

A central processing unit (CentralProcessing Unit, abbreviated as CPU) is used as an operation and control core of the computer system, and is a final execution unit for information processing and program running. A Central Processing Unit (CPU), which is one of the main devices of an electronic computer, is a core component in the computer. Its function is mainly to interpret computer instructions and process data in computer software. The CPU is a core component in the computer responsible for reading instructions, decoding the instructions and executing the instructions.

When the CPU works, a large amount of heat is generated, if the heat is not timely emitted, the CPU is crashed, and if the heat is heavy, the CPU is burnt out, and the CPU radiator is used for radiating the heat of the CPU, so that the radiator plays a decisive role in the stable operation of the CPU. Air-cooled heat sinks, which are the most common types of heat sinks, include one cooling fan and one heat sink. The principle is that the heat generated by the CPU is transferred to the radiating fin, and then the heat is taken away by the fan. In order to firmly and tightly contact the radiator with the CPU, a fastener is used to fix the radiator.

The chinese patent publication No. CN2634657Y discloses an improved cpu radiator structure, in which a concave notch groove 121 is provided, so that a fastener 3 can be inserted into the notch groove 121 to facilitate assembly, and then the radiator is fixed on a base 5 by the fastener 3 to be in close contact with a heat source body 4. According to the scheme, the buckle is installed through the notch groove formed in the center of the side part of the radiator, so that the radiator is attached to the heat source body to radiate heat. However, the main acting force of the buckle is only in the middle of the radiator, which easily causes that the side of the radiator and the heat source body cannot be tightly attached to each other, and heat dissipation is affected.

Chinese patent publication No. CN2431642Y discloses a heat dissipating device assembly, which comprises a heat sink and a pair of fasteners, wherein the heat sink comprises a base, and two opposite ends of the base are respectively provided with a long groove for positioning the pair of fasteners. The scheme is that grooves are respectively arranged on two opposite end parts of the base, so that a pair of buckling pieces are used for fixing the radiator. Although the problem that two sides of the radiator cannot be tightly attached is solved, the middle part of the bottom surface of the radiator is easy to bear uneven force, so that gaps are generated, and heat dissipation is affected.

In addition, when the radiator is subjected to transverse force, the buckle is easy to trip from the fixed state, so that the radiator is separated from contact with the central processing unit, and serious consequences are caused.

Therefore, the technical problem to be solved is how to provide a radiator with enhanced stability, which can enable the middle part of the radiator to be tightly attached to a heating source, and can enable the corner part of the radiator to be tightly attached to the heating source, and the radiator is not easy to trip when receiving transverse force, so that the radiator is firmly attached to the heating source, and the radiating effect of the radiator on the heating source is improved.

Detailed Description

The following description of the technical solutions in the embodiments of the present utility model will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 8, in a first embodiment of the present utility model, a heat sink with enhanced stability includes a heat conducting base 10, a fastening rod 20 and a fan 30, wherein the fastening rod 20 is movably connected to the heat conducting base 10 and is used for fixing the heat sink to an external device (not shown), and the fan 30 is fixedly connected to the heat conducting base 10; the heat conducting base 10 is provided with a bottom surface 12, a top surface 13 and side surfaces 14, the bottom surface 12 is used for abutting against an external heat generating source (not shown in the figure), and the fan 30 is mounted on the top surface 13; the heat conducting seat 10 is provided with a groove 15, the groove 15 extends from the top surface 13 to the bottom surface 12 to a certain depth, and the projection of the central axis of the groove 15 in the long side direction on the bottom surface 12 coincides with the diagonal line of the bottom surface 12; the buckling rod 20 is movably connected in the groove 15. The heat conducting seat 10 is also provided with a heat radiating fin 11, and the heat radiating fin 11 is composed of a plurality of fin-shaped heat radiating metal sheets.

Specifically, as the performance of computers becomes more and more robust, the main frequency of their central processing units becomes higher and higher, and the temperatures generated thereby become higher and higher. The existing computer is required to be provided with corresponding radiators during production or assembly, so that the heat of the central processing unit is radiated, the temperature of the central processing unit is reduced, and the faults of damage or downtime of the central processing unit are avoided. Of which air-cooled heat sinks are the most common type of heat sink, typically include a heat dissipating fan 30 and a heat dissipating metal block. The principle is that the heat generated by the CPU is transferred to the radiating fin 11, and then the air flow is driven by the fan 30 to take away the heat. For efficient heat transfer, the heat sink needs to be firmly in close contact with the cpu, and thus, the heat sink needs to be fixed in place using corresponding fasteners. The conventional buckle is fixed by the grooves 15 parallel to the side parts of the heat conducting seat 10, which cannot well apply uniform adhesion force to the bottom surface 12 of the heat conducting seat 10, and cannot perform uniform close adhesion connection, so that uneven stress is easy to occur, and gaps are generated to influence heat dissipation. The radiator is easy to be disengaged from the fixed state when being subjected to transverse force, so that the radiator is separated from the CPU, and serious consequences are caused.

Therefore, by providing the grooves 15 diagonally matching with the bottom surface 12 of the heat conducting seat 10, the buckling rod 20 can pass through two edges of the heat conducting seat 10, so that the radiator is better fixed at a proper position, a close fitting state is formed between the bottom surface 12 of the heat conducting seat 10 and an external heat generating source, and the heat dissipation performance of the radiator is enhanced. It can be appreciated that the fastening rod 20 may be made of a metal material with a certain elasticity, so that the heat conducting base 10 may be better tightly attached to an external heating source to form a fixed connection state under the driving of the elasticity of the fastening rod 20.

The buckling rod 20 is provided with a first buckling rod 25 and a second buckling rod 26, the first buckling rod 25 is movably connected in the first groove 16, and the second buckling rod 26 is movably connected in the second groove 17.

Specifically, in order to further improve the stability of the heat sink, the first groove 16 and the second groove 17 intersecting with each other may be further provided, and the first buckling rod 25 and the second buckling rod 26 respectively pass through the first groove 16 and the second groove 17, so that the buckling rod 20 may pass through four diagonal positions of the heat conducting seat 10, and further, the heat conducting seat 10 is more firmly fixed on an external heat generating source, so as to achieve close adhesion between the heat conducting seat 10 and the external heat generating source, and enhance the heat dissipation effect. It can be appreciated that the depth of the recess 15 is preferably smaller than the height of the heat sink 11, so that when the fastening rod 20 abuts against the bottom of the recess 15, the heat sink 11 with a certain height is still left between the fastening rod 20 and the bottom 12 of the heat conducting base 10, and heat dissipation from the heat sink 11 can be continued after the air flow passes through the fastening rod 20.

As shown in fig. 2 to 4, the fastening rod 20 is preferably provided with a first hook 23 and a second hook 24, and the first hook 23 and the second hook 24 are detachably connected to an external fixing rod (not shown) respectively, thereby fixing the radiator to an external device; the first hook 23 is fixedly connected to the buckling rod 20, and the second hook 24 is movably connected to the buckling rod 20. The buckling rod 20 is provided with a pressing portion 21, the pressing portion 21 is fixedly connected to the buckling rod 20 and located between the first hook 23 and the second hook 24, and the pressing portion 21 and the bottom of the groove 15 form an abutting state, so that the buckling rod 20 stably forms limiting fixation on the heat conducting seat 10.

Specifically, in order to make the buckling rod 20 be better matched and connected with an external fixing rod, corresponding hooks can be further arranged on the buckling rod 20, one of the hooks can be fixedly connected with the buckling rod 20, and the other hook can be movably connected with the buckling rod 20, so that the operation can be better performed when the buckling rod is in buckled connection with the external fixing rod. It will be appreciated that two hooks of the buckle lever 20 may also be provided to be movably connected to the buckle lever 20 at the same time. In addition, in order to make the connection between the buckling rod 20 and the heat conducting seat 10 more stable, a corresponding pressing portion 21 may be disposed in the middle of the buckling rod 20, and the pressing portion 21 forms an abutment with the bottom of the groove 15, so that pressing force is transferred to the heat conducting seat 10, and thus the heat conducting seat 10 and an external heating source can be tightly attached.

As shown in fig. 3, the pressing portion 21 is preferably provided in a shape of a long bar, and a through hole 22 is provided at a middle portion of the long bar-shaped pressing portion 21, and the through hole 22 is used for passing the air current driven by the fan 30.

Specifically, in order to prevent the heat dissipation effect of the air flow on the heat dissipation plate 11 when the fastening rod 20 is fixedly connected with the heat conduction seat 10, a corresponding through hole 22 may be provided in the middle of the fastening rod 20, so that the air flow may pass through the through hole 22 and then blow onto the heat dissipation plate 11 to dissipate the heat.

And circular pressfitting portion 21 can also evenly disperse the pressfitting strength to heat conduction seat 10 to make the inseparable laminating between heat conduction seat 10 and the outside source that generates heat more firm, the condition in space can not appear, further reinforcing radiating effect.

In use, the cpu is first mounted on a motherboard (not shown) at a corresponding location, and then the heat sink is mounted on a motherboard at a corresponding connector (not shown). The first hook 23 can be firstly mounted on the fixing rod on the main board, and then the second hook 24 is pressed to enable the buckling rod 20 to be elastically deformed to a certain extent, so that the second hook 24 is smoothly mounted on the fixing rod on the main board.
