Description

Technical Field

[0001] The utility model belongs to the technical field of radiators, and relates to a focusing air duct structure and a heat dissipation device with a focusing air duct structure. Background Technique

[0002] Existing radiators are usually set as open tower radiators. During the process of air flow passing through the tower radiator, due to the open structure connecting the tower radiator and the external environment, some of the air flow participating in heat dissipation will escape from the normally open gaps and channels, resulting in some air flow not passing through the heat sink structure for sufficient heat exchange, thus causing waste of air flow. Moreover, the air flow is relatively dispersed when passing through the tower heat sink and cannot flow through the heat sink concentratedly and quickly. Therefore, when the air flow exchanges heat with the heat sink and heats up, it cannot leave the heat exchange area quickly and effectively, thereby reducing the heat dissipation efficiency. At the same time, the heat sink assembly in the existing tower radiator is usually directly buckled inside the machine body, which will cause the heat accumulated on the radiator to be transferred to the contacting or adjacent components, also affecting the heat dissipation effect.

[0003] Therefore, aiming at the above problems existing in the existing tower radiator, the utility model discloses a focusing air duct structure and a heat dissipation device with a focusing air duct structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a focusing air duct structure and a heat dissipation device with a focusing air duct structure. By setting a relatively closed focusing air duct outside the heat sink, the air flow can pass through the heat sink concentratedly to achieve efficient heat exchange, and at the same time, the heated air flow can quickly converge and be discharged to avoid affecting the heat dissipation efficiency of the radiator.

[0005] The utility model is realized by the following technical solutions:

[0006] A focusing air duct structure includes a sandwich bracket. Focusing air ducts are symmetrically arranged on both sides of the top of the sandwich bracket, and a first space is reserved between the two focusing air ducts on both sides. The diameter of the end of the focusing air duct far from the first space is smaller than the diameter of the end of the focusing air duct close to the first space, so as to form a focusing area between the end of the focusing air duct far from the first space and the end close to the first space.

[0007] The first space between the focusing air ducts is used to install air supply devices such as fans. The inside of the focusing air ducts is used to install tower heat sinks, and the focusing air ducts enclose the outside of the tower heat sinks. A focusing area is formed between the end of the focusing air duct far from the first space and the end close to the first space. The diameter of the focusing area gradually increases from the end of the focusing air duct far from the first space to the end close to the first space, and the end of the focusing area close to the first space is in close contact with the end face of the air supply device located in the first space. When the air supply device in the first space is started, the air flow is collected to the tower heat sink through the focusing air ducts enclosing the outside of the tower heat sink, so that the air flow passes through the tower heat sink for heat exchange more concentratedly, and the heat-exchanged air flow is quickly guided and discharged through the focusing area. At the same time, by enclosing the tower heat sink with the focusing air ducts, a large amount of heat emitted by the tower heat sink itself is avoided from spreading.

[0008] In order to better implement the present utility model, further, connection flanges are provided at the tops of both sides of the focusing air ducts, and at least one air duct fastener is provided between the connection flanges at the tops of both sides of the focusing air ducts.

[0009] In order to better implement the present utility model, further, the cross-section of the focusing air duct is rectangular, and the focusing air duct includes four enclosing surfaces connected in sequence, wherein two opposite enclosing surfaces are arranged parallel and horizontally, and the other two opposite enclosing surfaces are arranged obliquely to form a focusing area.

[0010] In order to better implement the present utility model, further, the cross-section of the focusing air duct is circular, and the focusing air duct includes an annular enclosing surface. The diameter of the end of the annular enclosing surface far from the first space is smaller than the diameter of the end of the annular enclosing surface close to the first space, so as to form a focusing area between the end of the annular enclosing surface far from the first space and the end of the annular enclosing surface close to the first space.

[0011] In order to better implement the present utility model, further, a plurality of flow dividing members are arranged on the inner wall of the focusing air duct at positions corresponding to the focusing area in parallel with the flow direction of the fluid.

[0012] In order to better implement the present utility model, further, at least one avoidance groove and / or avoidance area is provided on the inner wall of the focusing air duct.

[0013] In order to better implement the present utility model, further, a positioning flange is provided at the bottom of the focusing air duct, a positioning groove engaged with the positioning flange is provided at the top of the sandwich bracket, a threaded hole is provided on the bottom end face of the positioning flange, a screw is passed through the positioning groove, and the screw is in threaded engagement with the threaded hole.

[0014] A heat dissipation device with a focusing air duct structure includes a focusing air duct structure, a fan, and a tower heat sink. The fan is installed in the first space between the focusing air ducts on both sides, and the end faces on both sides of the fan are respectively attached to the end faces of the focusing air ducts. A tower heat sink is arranged inside the focusing air ducts. The focusing air ducts are arranged around the outside of the tower heat sink, and the fluid passing through the tower heat sink is communicated with the fan through the focusing area.

[0015] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0016] (1) In the present utility model, by arranging focusing air ducts on the left and right sides of the fan and arranging a tower heat sink inside the focusing air ducts, a relatively concentrated and enclosed space is formed outside the tower heat sink through the focusing air ducts, so that the air flow generated when the fan works can pass through the tower heat sink more convergently and concentratedly, avoiding the dispersion of the air flow and ensuring the heat exchange efficiency between the air flow and the tower heat sink. At the same time, through the converging effect of the focusing air ducts and the power provided by the fan, the heated air flow can quickly pass through the tower heat sink, avoiding the heated air flow from reducing the heat dissipation effect of the tower heat sink.

[0017] (2) In the present utility model, by enclosing and arranging focusing air ducts outside the tower heat sink, direct contact between the tower heat sink and other components is isolated, avoiding a large amount of heat emitted by the tower heat sink from being transferred to other components.

[0018] (3) In the present utility model, a fan is arranged between the focusing air ducts on both sides. The end face of the fan contacts the focusing air ducts instead of directly contacting the tower heat sink, thereby avoiding the direct transfer of the heat of the tower heat sink to the fan. At the same time, only a fan with a corresponding specification needs to be set according to the shape of the focusing air ducts, and a larger fan can be used to adapt to a smaller tower heat sink, thereby improving the heat dissipation efficiency.

[0030] Example 1:

[0031] A focusing air duct structure of this embodiment includes a sandwich bracket 1. On both sides of the top of the sandwich bracket 1, focusing air ducts 2 are symmetrically arranged, and a first space 100 is reserved between the two focusing air ducts 2. The diameter of the end of the focusing air duct 2 far from the first space 100 is smaller than that of the end of the focusing air duct 2 close to the first space 100, so as to form a focusing area 200 between the end of the focusing air duct 2 far from the first space 100 and the end close to the first space 100.

[0032] The sandwich bracket 1 is used to install and fix the focusing air ducts 2. A first space 100 is formed between the focusing air ducts 2 arranged symmetrically on the left and right sides. The first space 100 is used to install air supply devices such as fans, so that air flow can flow between the two focusing air ducts 2. The inside of the focusing air duct 2 is used to install a tower heat sink. The diameter of the end of the focusing air duct 2 far from the first space 100 is smaller than that of the end of the focusing air duct 2 close to the first space 100. Thus, a stepped focusing area 200 is formed between the inner wall of the focusing air duct 2 and the tower heat sink, and the diameter of the focusing area gradually increases in the direction from the end of the focusing air duct 2 far from the first space 100 to the end close to the first space 100. After the fan is started, the air flow flows from one focusing air duct 2 to another focusing air duct 2, and the air flow is converged to the tower heat sink through the enclosed structure of the focusing channel 2, making the air flow passing through the tower heat sink more concentrated, thereby improving the heat exchange efficiency of the tower heat sink. At the same time, a relatively enclosed space is formed outside the tower heat sink through the focusing air duct 2 to prevent a large amount of heat dissipated by the tower heat sink itself from diffusing into the external environment. And through the focusing effect of the focusing air duct 2, not only is the air flow more concentrated, but when the air flow passes through the focusing area 200 of the left focusing air duct 2, its flow diameter changes from small to large, thus ensuring that the air flow has sufficient contact area with the tower heat sink. When the air flow passes through the focusing area 200 of the right focusing air duct 2, its flow diameter changes from large to small, enabling the air flow to quickly flow out of the focusing air duct 2.

[0033] Furthermore, connection flanges are provided at the tops of the two focusing air ducts 2, and at least one air duct fastener 3 is provided between the connection flanges at the tops of the two focusing air ducts 2. The two ends of the air duct fastener 3 are provided with slots corresponding to the connection flanges for snap connection. The air duct fastener 3 is snapped and installed between the tops of the two focusing air ducts 2 to further fix the two focusing air ducts 2 and ensure that the end face of the focusing air duct 2 can be closely attached to the end face of the fan inside the first space 100 to prevent air leakage.
