2. Description of the Prior Art
A conventional rack server and a conventional blade server both include the graphic processor and the main controller. A connection port of the main controller is usually disposed on a surface of the server that does not face the user for preferred aesthetic. A connection port of the graphic processor is disposed on the other surface of the server that faces the user for convenient assembly and disassembly of the connection port. With the advanced technology, operation efficiency of the graphic processor is increased to effectively execute signal processing procedures of the high quality and 3D image, so that the graphic processor is collocated with an active heat dissipating unit to rapidly dissipate heat generated from the graphic processor for increasing the operation efficiency of the graphic processor.
However, the graphic processor with the active heat dissipating unit exhausts airflow with the heat (the thermal current) out of the server via the surface that faces the user, the main controller further exhausts the airflow with the heat (the thermal current) out of the server via the surface that does not face the user. Direction of a heat dissipating airflow field of the graphic processor is different from direction of the heat dissipating airflow field of the main controller, and the reverse airflow fields result in decrease of the heat dissipating efficiency of the graphic processor and the main controller. Therefore, design of a channel diversion device capable of adjusting heat dissipating direction of different electronic components is an important issue in the related mechanical industry.

DETAILED DESCRIPTION
Please refer to FIG. 1. FIG. 1 is a diagram of a heat dissipating system 10 according to an embodiment of the present invention. The heat dissipating system 10 includes a casing 12 and a channel diversion device 14. The casing 12 can include a first area 16 and a second area 18. The channel diversion device 14 is disposed inside the first area 16, and a controller 20 of the heat dissipating system 10 can be disposed inside the second area 18. The channel diversion device 14 supports an electronic component 22, such as the heat dissipating component with an active radiator. Thermal current (airflow with heat) generated from the electronic component 22 can be exhausted from the first area 16 along a first direction D1. A moving direction of the airflow with the heat is turned by the channel diversion device 14, the thermal current from the electronic component 22 can move from the first area 16 to the second area 18, and is exhausted out of the casing 12 via the heat dissipating holes 121 along a second direction D2 different from the first direction D1 with heat generated from the controller 20, so as to achieve the preferred heat dissipating efficiency.
Please refer to FIG. 1 to FIG. 3. FIG. 2 is a diagram of the channel diversion device 14 in the other view according to the embodiment of the present invention. FIG. 3 is an assembly diagram of the channel diversion device 14 in the other view according to the embodiment of the present invention. The channel diversion device 14 includes a supporting structure 24, a piercing hole structure 26, a guiding baffle 28 and a collecting mask 30. The supporting structure 24 includes a first structural layer 32 and a second structural layer 34, and the first structural layer 32 is connected to the second structural layer 34 in a stack manner. The electronic component 22 can be disposed inside the first structural layer 32 of the supporting structure 24, and the active radiator 221 of the electronic component 22 faces the second structural layer 34 to inhale external airflow. An opening 36 is formed on the second structural layer 34. The external airflow moves into the supporting structure 24 via the opening 36.
It should be mentioned that the first area 16 and the second area 18 of the casing 12 can be isolated by the supporting structure 24 in an airtight manner, so the thermal current generated from the electronic component 22 cannot move from the first area 16 to the second area 18 directly. The airflow with the heat is guided by the collecting mask 30 to move toward the second area 18 through an outside of the supporting structure 24, and the channel diversion device 14 can adjust a heat dissipating airflow field of the electronic component 22 in the same direction as the heat dissipating airflow field of the controller 20.
The piercing hole structure 26 is formed on a lateral wall of the first structural layer 32. The inner airflow of the channel diversion device 14 can move out of the supporting structure 24 via the piercing hole structure 26. The guiding baffle 28 is disposed by a side of the opening 36 on the second structural layer 34. The guiding baffle 28 can increase an inhaling angle of the opening 36, so as to guide a great quantity of the airflow into the supporting structure 24 via the opening 36. Generally, the guiding baffle 28 can preferably include at least one inclined portion 38 disposed by the opening 36. The inclined portion 38 can guide the great quantity of the external airflow into the supporting structure 24 rapidly, so as to create the large airflow rate in short time and to increase the heat exchanging efficiency of the heat dissipating system 10.
The collecting mask 30 is disposed by the first structural layer 32 to cover the piercing hole structure 26. A direction (which equals the second direction D2 substantially) of an outlet 301 of the collecting mask 30 points toward the second area 18, and is different from a direction (which equals the first direction D1 substantially) of the opening 36 on the second structural layer 34. In this embodiment, the guiding baffle 28 and the collecting mask 30 are filled inside a gap between the supporting structure 24 and the casing 12, so as to prevent the airflow from moving between the supporting structure 24 and the casing 12 via the path excluding the guiding baffle 28 and the collecting mask 30. It is to say, the supporting structure 24 and the casing 12 are isolated by an assembly of the guiding baffle 28 and the collecting mask 30. Thus, the internal airflow of the supporting structure 24 can move into the collecting mask 30 through the piercing hole structure 26 along the first direction D1, the collecting mask 30 turns the moving direction of the airflow, and the airflow moves toward the second area 18 of the casing 12 along the second direction D2 for an aim of adjusting the airflow direction in the present invention.
As shown in FIG. 1 to FIG. 3, the guiding baffle 28 and the collecting mask 30 are isolated in the airtight manner and respectively disposed on the second structural layer 34 and the first structural layer 32, so that the airflow moving from the outside of the casing 12 into the supporting structure 24 via the guiding baffle 28 cannot directly enter the collecting mask 30. The airflow passes through the guiding baffle 28 to move into the supporting structure 24, then continuously passes through the second structural layer 34 and the first structural layer 32 in sequence, and moves toward the collecting mask 30 via the piercing hole structure 26. The collecting mask 30 turns the moving direction of the airflow. Therefore, a width W1 of the collecting mask 30 can be substantially greater than a width W2 of the supporting structure 24, which means an end (or two ends) of the collecting mask 30 protrudes from a boundary of the supporting structure 24, and the airflow out of the supporting structure 24 can be reversed by the collecting mask 30 and move relative to outer walls of the supporting structure 24 along the second direction D2.
Please refer to FIG. 4 and FIG. 5. FIG. 4 and FIG. 5 respectively are diagrams of the guiding baffle 28 according to different embodiments of the present invention. As shown in FIG. 4, the inclined portion 38′ of the guiding baffle 28 can be an arc curved structure. As shown in FIG. 5, the inclined portion 38′ of the guiding baffle 28 can be a sunken structure with any shapes. The inclined portion is utilized to expand dimensions of the opening for increasing the quantity of the airflow entering the supporting structure 24. Structure capable of expending the dimensions of the opening 36 belongs to the design scope of the guiding baffle in the present invention, which is not limited to ones of the above-mentioned embodiment, and a detailed description is omitted herein for simplicity.
Please refer to FIG. 1 and FIG. 6. FIG. 6 is a diagram of the airflow trend of the heat dissipating system 10 according to the embodiment of the present invention. As shown in FIG. 6, the active radiator 221 of the electronic component 22 is actuated, the external airflow (the cold air) moves from the outside of the heat dissipating system 10 into the second structural layer 34 of the supporting structure 24 via the opening 36 along an arrow shown in FIG. 6. The electronic component 22 disposed on the first structural layer 32 inhales the external airflow (the cold air) into the structure for heat exchange, then the airflow moves along an arrow from the second structural layer 34 to the first structural layer 32 as shown in FIG. 6.
The airflow with the heat (the thermal current or the warm air) is exhausted by the electronic component 22. The airflow (the warm air) passes through the piercing hole structure 26 along the first direction D1 to move out of the supporting structure 24. After leaving the supporting structure 24, the airflow (the warm air) enters the collecting mask 30 immediately, as an arrow shown in FIG. 6. The moving direction of the airflow (the warm air) is reversed by the collecting mask 30, so that the airflow (the warm air) moves from the outlet 301 to the second area 18 along the second direction D2, and is away from the casing 12 via the heat dissipating holes 121. Therefore, the present invention can exhaust the thermal current inside the heat dissipating system 10, such as the heat generated from the controller 20 or the electronic component 22, from the casing 12 along the same direction (the second direction D2).
In conclusion, the channel diversion device of the present invention utilizes the guiding baffle and the collecting mask to isolate the supporting structure and the casing in the airtight manner. Even through connection ports of the electronic component and the controller respectively face different sides of the casing, the present invention can isolate the thermal current (the airflow with the heat) generated from the electronic component disposed inside the supporting structure and from the controller disposed inside the second area of the casing without reverse conflict. Further, the collecting mask of the channel diversion device can reverse the moving direction of the airflow exhausting from the supporting structure, so that the channel diversion device is able to combine the thermal current from the electronic component and the controller as an integrated current, rather than generate the turbulence, for increasing the heat dissipating efficiency of the heat dissipating system.
In addition, the channel diversion device of the present invention further utilizes isolation between the guiding baffle and the collecting mask to divide the external airflow (the cold air) from the airflow (the warm air) through the electronic component, so as to effectively prevent the heat dissipating efficiency of the heat dissipating system from decrease because of an reverse of the thermal current. Comparing to the prior art, the channel diversion device and the related heat dissipating system of the present invention can solve drawbacks of the low heat dissipating efficiency due to the reverse of the thermal current in the conventional device. The present invention can simultaneously increase the heat dissipating efficiency of the inner flow field (the electronic component) and the outer flow field (the controller), so that the channel diversion device is suitably applied to the blade server and the rack server for increasing expansion efficiency of the related circuit board, such as the PCI-E card.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
