Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation equipment, in particular to a radiator fan structure. Background Art

[0002] The radiator is an important component of electronic equipment, engines or other high-temperature equipment. It is used to dissipate the heat generated by the equipment and keep the temperature of the equipment stable.

[0003] The radiator fan is usually located outside the radiator and accelerates the transfer of heat by generating airflow. It draws in ambient air through the operation of the fan blades and exhausts the hot air out of the device to keep the temperature of the device within a safe range.

[0004] Radiator fans are usually used in conjunction with radiators. The radiator is placed near the heat source of the device. The fan blows cold air through the surface of the radiator to dissipate the heat. The speed and power of the radiator fan can be adjusted according to the heat dissipation requirements of the device.

[0005] In the prior art, a radiator fan usually forms a radiator blower structure together with a radiator and a shell, and the two are generally in contact with each other and installed in combination, or a certain space is left between them, but the blower and the radiator are still fixed at specified positions. Since they cannot be adjusted, the position of the fan is set too close to the radiator. Although it has a better heat dissipation effect, when the distance is too small, the air flow will be stronger, generating greater wind noise, and the equipment will not generate too much heat when running at low power for a short time. Therefore, we propose a radiator blower structure. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings existing in the prior art. The radiator fan usually forms a radiator fan structure with the radiator and the shell, and the two are generally in contact with each other and installed in combination, or a certain space is left between them, but the fan and the radiator are still fixed in designated positions. Since they cannot be adjusted, the position of the fan is set too close to the radiator. Although it has a better heat dissipation effect, when the distance is too small, the air flow will be stronger, generating greater wind noise, and the equipment will not generate too much heat when running at low power for a short time.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A radiator fan structure, comprising a housing, a heat dissipation structure, a spacing adjustment component, a radiator, a heat dissipation fan and a dustproof component, wherein the heat dissipation structure is disposed in the housing, and the spacing adjustment component is installed in the heat dissipation structure;

[0009] The heat dissipation structure includes a main heat dissipation channel, an auxiliary heat dissipation channel and a radiator mounting frame. The radiator mounting frame is opened on the back of the shell and is connected to the main heat dissipation channel. The auxiliary heat dissipation channel has four groups, which are opened inside the shell and are located around the main heat dissipation channel and are connected to the radiator mounting frame. A dustproof component storage groove is opened on the top of the main heat dissipation channel.

[0010] The radiator and the cooling fan are respectively installed inside the main cooling channel and the radiator mounting frame, and the dustproof component is installed above the main cooling channel;

[0011] The spacing adjustment assembly includes a linear guide rail opened at the lower center of the radiator along the length direction, a linear slider is installed inside the linear guide rail at the bottom of the radiator, auxiliary slide grooves are symmetrically opened at the center of both sides of the radiator, a guide rod is arranged inside the auxiliary slide groove, and sliders are installed on the periphery of the guide rod and on both sides of the radiator;

[0012] The dustproof component storage slot includes a motor, and an output end of the motor extends to the dustproof component storage slot and a dust blocking plate is installed therein.

[0013] As a preferred solution of the utility model, mounting holes are provided on the front and back sides of the shell near the corners. The mounting holes on the front side are used for mounting with the dust cover, and the mounting holes on the back side are used for mounting with the heat source of the equipment.

[0014] The technical effect of adopting the above further scheme is: it can be installed through the mounting hole and the dust cover, can be disassembled, and the outside of the radiator fan is protected from dust, and the mounting hole is installed with the heat source of the equipment to conduct heat.

[0015] As a preferred solution of the utility model, the output direction of the heat dissipation fan is toward the front side of the housing, the heat dissipation end of the radiator corresponds to the heat dissipation fan, and a temperature sensor is installed on the radiator.

[0016] As a preferred solution of the utility model, the linear slider is slidably connected to the linear guide rail, and the slider is slidably connected to the guide rod.

[0017] The technical effect of adopting the above further scheme is: the distance between the cooling fan and the radiator is adjusted when the linear slider and the linear guide rail are slidably connected, and the sliding connection between the slider and the guide rod assists the displacement of the cooling fan, thereby avoiding the vibration generated during the operation of the cooling fan, which may cause the cooling fan structure to be unstable.

[0018] As a preferred solution of the utility model, the end of the dust blocking plate corresponding to the motor is rotatably connected to the dustproof component storage groove through a rotating shaft.

[0019] The technical effect of adopting the above further scheme is: the output end is driven to rotate through the operation of the motor. Since the end of the dust blocking plate corresponding to the motor is rotatably connected to the dust blocking component storage groove through the rotating shaft, the rotation of the dust blocking plate driven by the motor is not affected, and the stability of the dust blocking plate is ensured.

[0020] As a preferred solution of the utility model, a plurality of cooling fans are installed near the radiator mounting frame in the four auxiliary heat dissipation channels.

[0021] The technical effect of adopting the above further solution is that the heat generated in the early stage of equipment operation or in short-term low-power operation can be dissipated through the operation of the cooling fan, without the need for the operation of the fan to generate a lot of noise.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] 1. In the utility model, different effects can be produced by adjusting the distance between the heat dissipation fan and the radiator through the distance adjustment component. First, the heat dissipation effect is enhanced. By reducing the distance between the radiator fan and the radiator, the contact area between them can be increased, and the heat conduction efficiency can be improved. When the distance is reduced, the fan can better push air through the radiator, increase the heat exchange surface area of ​​the radiator, and thus enhance the overall heat dissipation effect, which will lead to a reduction in the temperature of the equipment, improve the heat dissipation efficiency and the performance of the equipment. Secondly, the distance between the radiator fan and the radiator is increased to reduce the fan noise. When the distance increases, the air flow will decrease, reducing wind noise, avoiding excessive sound interference and affecting the user's experience. Therefore, by adjusting the distance between the radiator fan and the radiator, a balance between heat dissipation effect and noise control can be achieved.

[0024] 2. In the utility model, the heat generated in the initial stage of equipment operation or short-term low-power operation is dissipated through the design of auxiliary heat dissipation channels and dust-proof components. There is no need for the operation of the fan to generate a lot of noise, and the closure of the dust-proof plate prevents external moisture or fine dust from entering, further improving the use effect of the radiator fan.
