Description

Technical Field

[0001] The utility model belongs to the technical field of radiators, and in particular relates to an air-cooled radiator. Background Art

[0002] An integrated circuit is a miniature electronic device that uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit. It is made on a small piece or several small pieces of semiconductor chips or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit function. All the components have formed a whole in structure, making a major step forward in the direction of miniaturization, low power consumption, intelligence and high reliability of electronic components.

[0003] However, integrated circuits will generate high temperatures during use, which will not only cause some components of the integrated circuit to operate unstably and shorten their service life, but may even cause some components to burn out. To solve this problem, integrated circuits are usually equipped with air-cooled radiators to dissipate heat and cool them down. Existing air-cooled radiators are usually equipped with heat pipes. The heat of the integrated circuit is transferred to the heat pipes, and the natural flow of wind takes away the heat from the heat pipes to achieve heat dissipation of the integrated circuit. However, when the integrated circuit generates high heat, the heat dissipation efficiency of such air-cooled radiators is far from enough. Utility Model Content

Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0031] The technical solution of the utility model is described in detail below with specific embodiments.

[0032] Please also read Figure 1 and Figure 2 The embodiment of the utility model provides an air-cooled radiator, including a base 2, a heat pipe 4, a fin 5, a fan 3 and a shell 1, wherein the base 2 is used to abut against the heating element and absorb the heat of the heating element; the heat pipe 4 is plugged and connected to the base 2 to absorb the heat of the base 2, and a plurality of heat pipes 4 are provided, which are arranged in a rectangular array; the fin 5 is welded and connected to the heat pipe 4 to transfer the heat of the heat pipe 4; the fan 3 is arranged in the axial direction of any one of the heat pipes 4 to generate airflow and accelerate the dissipation of heat from the heat pipe 4 and the fin 5; the shell 1 is covered with the base 2, the heat pipe 4, the fin 5 and the fan 3; the heating element in this embodiment specifically refers to an integrated circuit, through the above-mentioned arrangement, the base 2 abuts against the integrated circuit, and the heat of the integrated circuit is transferred to the base 2, the heat pipe 4 and the fin 5 in turn, and the fan 3 rotates to generate airflow, which accelerates the heat dissipation from the heat pipe 4 and the fin 5, thereby achieving the effect of rapid cooling and preventing the integrated circuit from running unstably, shortening its life and burning.

[0033] For further information, see Figure 2and Figure 3 In this embodiment, the heat pipes 4 are arranged in a rectangular array of (m rows × n columns), and the extension direction of the m rows is defined as the width direction of the rectangle, and the extension direction of the n rows is defined as the length direction of the rectangle. Specifically, Figure 3 As shown, in this embodiment, m is 7, Figure 2 It can be seen that n is 13, and accordingly, in this embodiment, the extension direction of the fin 5 is along the length direction of the rectangle, that is, the extension direction of the nth column, and the number of fins 5 is the same as the number of rows in the width direction of the rectangle, that is, the value of the fin 5 is also m, which is 7. Any fin 5 is at least partially in contact with all the heat pipes 4 in the same row to fully transfer the heat of the heat pipe 4 to the fin 5. Compared with the heat of the heat pipe 4 directly dissipating into the air, the sheet-like fin 5 can effectively increase the contact area with the air and increase the heat exchange efficiency. It can be understood that the extension direction of the fin 5 can also be changed to be along the width direction of the rectangle, and it can also be changed to the extension direction of some fins 5 along the length direction of the rectangle, and the extension direction of some fins 5 along the width direction of the rectangle.

Figure 4 In this embodiment, the fin 5 includes an extension portion 51 and a fitting portion 52. The extension direction of the extension portion 51 is parallel to the length direction of the rectangular array. The fitting portion 52 at least fits with part of the heat pipe 4. In this embodiment, the heat pipe 4 is cylindrical. The cross-section of the fitting portion 52 along the vertical direction is semicircular. The size of the fitting portion 52 matches the size of the heat pipe 4 and half surrounds the heat pipe 4. Since any fin 5 abuts against all the heat pipes 4 in the same row, the extension portion 51 and the fitting portion 52 should be arranged alternately.

With such arrangement, when the fan 3 rotates, the air flow enters the shell 1 from the air inlet 12, gradually moves from the bottom of the heat pipe 4 to the top of the heat pipe 4, and then to the fan 3 and the air outlet 11, which can fully take away the heat on the heat pipe 4 and the fin 5 and increase the heat exchange efficiency; specifically, the fan 3 includes a bracket 31 and blades 32, the blades 32 are rotatably connected to the bracket 31, and the bracket 31 is fixedly connected to the shell 1, so that the position of the fan 3 is fixed and will not be offset during the rotation process.

[0037] It can be understood that in this embodiment, the shell 1 is a rectangular cover without a bottom surface, and the number of air inlet 12 is set to one, and one air inlet 12 is located on any non-top side of the rectangular parallelepiped. Of course, it can also be configured as two or more, located on the same side or different sides. Such changes fall within the protection scope of the present utility model; further, the shell 1 can also be set to a cylindrical or other shaped cover, which will not be further elaborated here.

[0038] Furthermore, the housing 1 is provided with an electrical interface 13 for supplying power to the fan 3 .

[0039] In summary, the utility model provides an air-cooled radiator, comprising a base 2, a heat pipe 4, a fin 5, a fan 3 and a shell 1, wherein the base 2 is used to abut against the heating element to absorb the heat of the integrated circuit; the heat pipe 4 is plugged and connected to the base 2 to absorb the heat of the base 2, and a plurality of heat pipes 4 are provided and arranged in a rectangular array; the fins 5 are welded and connected to the heat pipe 4 to transfer the heat of the heat pipe 4; the fan 3 is arranged in the axial direction of any one of the heat pipes 4 to generate airflow and accelerate the dissipation of heat from the heat pipe 4 and the fin 5; the shell 1 is covered with the base 2, the heat pipe 4, the fin 5 and the fan 3; with such an arrangement, the base 2 abuts against the integrated circuit, and the heat of the integrated circuit is transferred to the base 2, the heat pipe 4 and the fin 5 in turn, and the fan 3 rotates to generate airflow to accelerate the dissipation of heat from the heat pipe 4 and the fin 5, thereby achieving the effect of rapid cooling and preventing the integrated circuit from running unstably, shortening its life and burning.
