Technical Field

The utility model relates to the technical field of radiators, in particular to a radiator with a fan group.

Background

A heat sink is a common internal device structure of a machine that is used to transfer heat generated by the machine or other equipment in a timely manner during operation to avoid affecting its proper operation. Common heat sinks can be classified into various types such as air cooling, heat pipe heat sinks, liquid cooling, semiconductor refrigeration, compressor refrigeration and the like according to a heat radiation mode. Most heat sinks absorb heat by contacting the surface of a heat generating component and then conduct the heat to a remote place by various methods to solve the heat dissipation problem.

The air-cooled radiator generally comprises a fan, radiating fins, a heat conduction base and a heat pipe, wherein the principle of the air-cooled radiator is that the heat conduction base or a soaking plate conducts heat of a heating element to the heat pipe, the heat pipe further conducts the heat to the radiating fins, and the heat on the radiating fins is blown away by the fan to radiate. In the prior art, wind generated when a fan rotates easily generates larger noise when being discharged out of an air outlet; meanwhile, the surface area of the radiating fin is smaller, and the radiating efficiency is lower.

It should be noted that, in practical application, the size of the heat dissipation fins 15 may be changed according to practical situations, so that the heat dissipation fin groups 11 form different three-dimensional structures, and the fans 12 may be arranged in parallel or not completely in parallel according to practical situations. In one embodiment, the heat dissipation fins 15 are in a diffusion shape in the first direction, the heat dissipation fin group 11 forms a prismatic table structure as shown in fig. 6, and a group of fans 12 are arranged at two sides in the second direction, and the fans 12 are not completely parallel. The fans 12 may be coaxially disposed or non-coaxially disposed on both sides in the second direction depending on the actual situation.

The fan 12 is used for blowing or exhausting air towards the inside of the heat radiation fin group 11 so as to cool the heat radiation fin group 11; when the fan 12 blows air into the heat radiation fin group 11, the air port is used as an air outlet, and at the moment, the side where the fan is positioned is an air inlet part, as shown in fig. 3; when the air is pumped into the heat radiation fin group 11, the air inlet is used as an air inlet, and at the moment, the side where the fan is located is an air outlet.

In practical application, the larger the surface area of the radiating fin is, the better the radiating effect is. Preferably, each heat dissipation fin 15 is provided with a plurality of guiding hollow structures 16, and a new surface can be generated on the heat dissipation fin 15 by adding one guiding hollow structure 16. In one embodiment, the size of the surface area of the heat sink fins 15 can be controlled by controlling the size of the guiding hollow structure 16, and the air flowing direction inside the heat sink fin group can be guided.

In a specific application, the guiding hollow structures 16 with different areas, shapes and directions arranged on the heat dissipation fins 15 can play different roles. Preferably, the guiding hollow structure 16 is designed to have a wind guiding function according to the movement direction of the air flow in the radiator, so as to accelerate the entry of cold air in the radiator and the export of heat.

In one embodiment, when the fan 12 sets make opposite blowing air flow in the radiator, because the interval between the adjacent heat dissipation fins 15 of the heat dissipation fin set 11 is smaller, the opposite air flow is blown out and then is collided and extruded in the interval, and is preferentially discharged to the outside of the left and right sides of the heat dissipation fin set 11, so that the side where the fan 12 is connected with the heat dissipation fin set 11 is used as an air inlet, and the air inlets arranged at the two sides in the preset third direction are used as air outlets. And then four air flowing directions and a first radiating fin guiding hollow structure are formed as shown in fig. 3, and a plurality of guiding hollow structures 16 on the radiating fins 15 are distributed on the radiating fins 15 according to the arc flowing direction of air from the air inlet to the air outlet.

Preferably, a plurality of heat pipes 13 are arranged on the heat dissipation fins 15 in a staggered manner in a row, so that heat in the heat pipes 13 is uniformly guided to the heat dissipation fins 15. The uniform distribution of the heat pipes 13 helps to transfer heat evenly into the fin group 11. Furthermore, the arrangement of the heat pipes 13 is designed based on the principle of minimum blocking caused by the air port, so that the heat pipes 13 can not block the air port as much as possible while conducting heat.

Preferably, the guiding hollow structure 16 may be designed to improve heat conduction efficiency, such as the second guiding hollow structure of the heat dissipation fins shown in fig. 4.

Meanwhile, the guiding hollow structure 21 in the guiding hollow structure II and the guiding hollow structure 21 are arranged more tightly, and the hollow parts are more, so that the effect of guiding hot air and heat to the upper air in the first direction can be achieved, and the heat transmission in the radiating fin group 11 is quickened.

Preferably, a fixed distance is provided between two adjacent layers of heat dissipation fins 15, so as to enable air flow to be stably exchanged in the radiator. The heat radiation fin group 11 is composed of a plurality of heat radiation fins 15 which are uniformly distributed, so as to realize uniform heat radiation. In addition, the distribution density of the heat dissipation fins 15 can be controlled according to the actual situation, so that the heat dissipation fins are unevenly distributed.

Preferably, the heat sink further comprises a connection frame 17 for connecting the fan 12, the connection frame 17 and the fan 12 together form a spacing space, and the heat dissipation fin group 11 is located in the spacing space.
