The scheme relates to a locking device of a computer cooling fan , in particular to a cooling fan locking device which is simple in structure and convenient to operate, and can quickly fix the fan device above a cooling fin without any tools.

  As shown in fig.1, the radiator includes:a base on which are fixed a plurality of heat-dissipating eel fins, which are wavy square heat-dissipating regions with u-shaped corners at the upper and lower ends continuously bent from metal sheets

The central position of the top surface of the hot area can be formed by fixing the fan on it. When in use, it passes through the base; The central contact surface at the bottom is in contact with the microprocessor (CPU) on the mainboard, and the heat energy generated by the CPU during operation is conducted out by the heat radiating fin and can enter

Cooperate with the fan step by step to forcibly dissipate heat to the outside of the computer host, so as to achieve the purpose of heat dissipation.

  The invention relates to a method for fixing a computer radiating fan on a radiating fin. Since screw holes or nuts cannot be arranged on the heat dissipation fins folded by metal sheets, a frame is additionally arranged on the top surface or the periphery of the heat dissipation fins, and a-large air vent 51 is arranged in the center of the frame, and

The fixing holes of the fan correspond to each other, and screw holes are arranged around the fixing holes, and the fan is locked on the frame by screws so as to radiate the radiating fins. For the above known computer radiator, when fixing the fan to the heat dissipation fin, it is necessary to add a frame and use tools to fix the fan

Locking on the frame with screws has high manufacturing cost, labor and time consuming, and inconvenient construction operation.

  The main purpose of the device is to provide a locking device for a computer cooling fan, which has simple structure and low manufacturing cost, and can quickly lock the fan on the cooling fin without any tools.

  The aim is achieved as follows:a locking device of a computer heat dissipation fan comprises a base with the bottom contacting with the top surface of a microprocessor and a plurality of heat dissipation fins arranged on the top surface of the base, wherein the fan is fixed on the top surface of a heat dissipation area formed by the plurality of heat dissipation fins,

The fastener for fixing the fan is composed of two fasteners with the same shape, each fastener is 90 degrees, left and right are rectangles, and hook parts corresponding to fan fixing holes are respectively arranged on the two sides of the upper end of the fastener, and at least one fastener is arranged on the bottom edge of the fastener to be buckled on the outermost side of the radiating fin

The hook part of the buckle hole is connected with the hook part at the upper end and the hook part at the lower edge by an arc-shaped elastic arm.

  When combined and used according to the above structure, the hook part at the upper end of the fastener is placed into the fixing hole of the fan, and the hook part at the lower edge of the fastener is pressed into the buckle hole reserved at the outermost side of the radiating fin, and the fan is clamped on the radiating fin through the elasticity of the elastic arm therebetween, so as to easily achieve the purpose.

And the fan assembly can be quickly fixed on the radiating fins.

  In order for your review committee members to have a deeper understanding and understanding of the structure, device and features of the utility model, the following is a detailed description of a preferred and feasible embodiment in conjunction with the drawings:

  Fig.1 is an illustration of a plane combination embodiment of a known computer radiator.

  Fig.2 is a perspective exploded view of the utility model.

  Fig.3 is a perspective combination diagram of the utility model.

  Fig.4 is an illustration of a plane combination embodiment of the utility model.

  Please refer to figs.2 and 3.the computer radiator 1 of this utility model is assembled on the computer motherboard for cooling the CPU.the cooling fan mainly comprises a base which can contact with the top surface of the microprocessor (CPU) at the bottom, and a plurality of cooling fins arranged on the top surface of the base

The top surface of the area formed by the plurality of radiating eel sheets is provided with a concave space, and a fan can be completely accommodated in the concave space and fixed so as to achieve the form of easy combination and small volume; The fastener for fixing the fan consists of two fasteners with the same shape, each fastener

The fastener is 90 degrees in side view and rectangular in left and right. The two sides of the upper end are respectively provided with a hook part corresponding to the fixing hole of the fan, and the bottom edge of the fastener is provided with at least one hook part which is buckled to the preset buckle hole at the outermost side of the radiating eel sheet and hooked at the hook part and the lower edge of the upper end

The parts 62 are connected by an arc-shaped elastic arm.

  Referring again to fig.4 according to the structure, when the device is used in combination with the type shown in fig.1, the hook part at the upper end of the fastener is put into the fixing hole of the fan, and the hook part at the lower edge of the fastener is pressed into the buckle hole reserved at the outermost side of the radiating eel sheet, and the fan is driven by the elasticity of the elastic arm therebetween

It is clamped on the radiating fin, and the fan assembly can be easily and quickly fixed on the radiating fin without any tools. The device can save the addition of known heat dissipation fins as shown in fig.1, the upper frame, screws and the like and can save the manufacturing and material costs.
