New description: [New technical field] The present invention relates to an air hood, and more particularly to an air hood having a selectively openable door panel to guide the flow direction of the internal airflow. [Prior Art] The rapid development and function of the electric moon 6? technology is often brought directly to people with a variety of new functions and services, and provides great convenience to people. However, the improvement of computer technology is mainly due to the increasing speed of operation of computer components. Therefore, the large amount of heat generated by riding also increases the temperature of the components themselves. Conversely, an increase in the temperature of the computer component itself can affect its own efficiency, even causing damage. For example, the CPU (ce_ IWssmg Unit, CPU) in the computer can no longer work under high temperature conditions. Therefore, it is good for high-speed operation and 1 computer component. It is a problem that the industry has to constantly improve and solve. This conventional method of dissipating heat is nothing more than adding a heat sink to the heating element, and the -powering fan is used to derive the amount of heat generated on the part and the heat sink. However, due to the size of the electric service system, the size of the fan to be equipped is also limited, and the use of a small face to make a body (4) is often unable to achieve a good heat dissipation effect. Therefore, the industry has been concentrating on the heat dissipation area on the board and the fan design - M325722 air duct to improve heat dissipation efficiency. For example, the windshield disclosed in the Republic of China New Patent Publication No. 2941δδ, the age-frame is connected to the cooling fan, and has a flexible-body-through passage, and the airflow generated by the fan The passage formed by the cover body can be guided to the heating element covered by the cover body, so as to guide the hood of the heat-generating component in the cover body to pass through the 'channel, and the channel cannot be controlled. The direction of flow of the airflow. The direction of airflow inside the enclosure depends on the structure inside the enclosure cover area. In general, the airflow is concentrated in blocks with low flow field resistance. Take a single hood and cover the two central parts (4) as an example. Since the two towel central processors and their heat sinks have the same resistance to airflow, the airflow through the two central processors will be roughly the same. However, when one of the central processing units is deactivated and removed, the area without the central processing unit has a small flow field resistance, so the air flow will be in the area without the central processing unit, resulting in the lack of a central processing unit still in use. Good heat dissipation. In view of this state, the hoisting will cover the air hood of the central office (fourth), or block the ventilation σ of the air hood by the object, and change the direction of the Wei flow, but the foregoing method _ is inconvenient. [New content] In the above problems, the purpose of this creation is to provide an air hood that can solve the problem that the air hood cannot control the flow direction of the airflow in the channel and affect its heat dissipation efficiency. In order to achieve the purpose of m, the present disclosure discloses a wind deflector for guiding the M325722 airflow through the heating element to facilitate the heat extraction. The guide group includes an ontology, at least a pivotal sigh, at least a door panel. The body cover is overlaid on the heating element, and has at least one vent. The pivoting seat is disposed on the body and located at a side of the vent, the pivoting seat has an arcuate groove, and the arcuate groove has a first end and a second end. The door panel is pivotally connected to the pivoting seat, and the door panel has at least one positioning post located on at least one side of the door panel and sliding on the arcuate slot for selectively holding the first end and the second end, thereby The door panel can be selectively opened or closed to determine whether airflow is allowed to pass through the vent to change the direction of flow of the airflow inside the air hood. The effect of this creation is that the air hood provided has a vent which can be selectively opened and closed, and can be selectively opened and closed by a plurality of vents to guide the flow direction of the airflow inside the hood. Therefore, the user can guide the main airflow according to the use condition or the location of the specific area and the specific heating element to achieve the better heat dissipation effect. Therefore, in this creation, the hood is a hood that can guide the flow direction of its internal airflow to enhance the 'hot effect. Moreover, the above-mentioned functions can make the computer equipment running at a high speed more stable. The above description of the present invention and the following description of the embodiments are used to explain the principles of the present invention and to provide further explanation of the scope of the patent application of the present invention. [Embodiment] 7 M325722 has a further understanding of the purpose, structure, features, and functions of the present invention, and is described in detail below with reference to the embodiments.

The body 1 has a first vent 111 and two second vents 112. The air flow enters the body 100 through the first vent (1) and flows out of the body 11 by the second vent 112. When the empty milk flow flows through the heat generating elements 1〇2 in the body 110, the heat energy generated by the heat generating elements (10) is collectively derived. Next, referring to "Fig. 1" and "Fig. 2A", the pivot socket 12 is disposed on the body 100 and located on the side of the second vent 112. In the embodiment proposed by the present invention, the pivoting seat 120 is located at two sides of each of the second vents 112 and extends away from the second vent 112. The pivoting socket 120 has an arcuate slot 122 and a pivoting slot 124. The arcuate slot 122 has a first end 1221 and a second M325722 1 221. The first 1221 further has a first positioning slot 125, and the second end 1222 further has a second setting slot 126. Referring to the "Fig. 1" and "Fig. 2A", the door panel 13 is pivotally connected to the pivot base 120, and the door panel 130 has two positioning posts 132 and two pivot posts 134. The pivoting posts 134 are located on opposite sides of the door panel 130 for inserting the hinges of the pivoting seats 12, and are connected to the slots 124 for pivoting the door panel 130 to the pivoting seats 12A. The cross-sectional area of the pivoting slot and the I24 is greater than the cross-sectional area of the pivoting post 134. The pivoting post 134 can not only pivot relative to the splicing base 120, but also can move in one of the first positions of the pivoting slot 124 and - between the second positions. That is to say, the door panel 13Q can move linearly with respect to the socket 12 in a predetermined stroke (the distance between the first position and the first position), in addition to being movable relative to the frame socket 120. . In the embodiment provided by the present invention, the insertion slot 124 has an L shape, and the first position and the second position refer to the pivotal connection and the two ends of the slot m. The L-shaped pivot slot 124 has a long side (four) and a short side 1242, and the L long side 1241 corresponds to the second end of the arcuate slot 122 and the short side. The _ end 1221 of the slot 122. The first position is the short side end of the slot 124, and the second position is the long end of the cabinet slot. Referring again to "Fig. 1" and "2aw % brother 2A", the two positioning posts 132 are located on opposite sides of the door panel 130, and the blades are inserted into the arcs of the two pivoting seats 12 _ 122 . The positioning post 132 slides in the arc 曰 W 曰 122 and moves between the first end 1221 and the second end 22 of the arcuate slot 122, since the first end U21 of the arcuate slot 122 has 9 M325722 for positioning The post 132 is fastened by the first positioning slot 25, and the second end 1222 has a second positioning slot 126 for the positioning post to be fastened. Therefore, the positioning post 132 can be selectively fastened by the first positioning slot 125 to the first end 1221, and the second positioning slot 125 can be fastened and fixed to the second end 1222. In the above embodiment, the socket 120 and the door panel 13 are adjacent to the second ventilation port 112, however, the present invention is not limited to the above embodiment. The call center socket 120 and the door panel 130 of the present invention may also be adjacent to the first vent (1), which can also achieve the purpose and effect of the creation. Next, please refer to "2A" to "2E", which is the schematic diagram of the decomposition step of the windshield for the operation of the present invention. When the plate 13_ is closed, the pivoting column m of the door plate is _ The first position of the slot m is fixed, and the positioning post 132 of the door bo is located in the first positioning slot (2) of the first end i22i of the arcuate slot 122, and is latched at the first end 1221, as shown in Figure 2A. Show. Then, the user can simply lift the door panel (10) as in the arrow 2A, and the pivot post 134 can be moved away from the first position. Positioning 125 ' as shown in "Figure 2". Then, the user pushes the door panel 130 along the curved slot 122, that is, in the direction of the arrow stomach in the "second map", so that the door panel 130 pivots relative to the pivoting slot 124 of the pivot socket 120, and The post 132 moves from the first end of the arcuate slot 2 to the second end 1222, as shown in the figure. Moreover, the user applies the pulling force of the door panel 130 along the direction indicated by the "second 2" towel, and moves the 10 M325722 pivoting post 134 to the second position of the pivoting slot 124, and causes the positioning post 132. Move to the second positioning slot 126 as shown in "Fig. 2D". Then, the user can naturally lower the door panel 130 so that the positioning post 132 is fastened and fixed to the second positioning slot 126 of the second end 1222, so that the door panel 130 is opened, as shown in FIG. 2E. Therefore, as described above, when the pivot post 134 is in the first position, the door panel 13Q is in an open state, and when the pivot post 134 is in the second position, the door panel 13 is in a closed state. Next, as shown in the "Fig. 3", the air hood 1 (8) of the present invention allows the second vents n2a, 112b to be selectively opened by the optional service and the sealing plate 13Q. Covering, therefore, when a door panel 13〇a is in an open state and the other door panel 130b is in a closed state, the airflow flowing into the first vent (1) can be directed to the opened first ventilation π 112a, so as to be close to being opened The thermal element 102 of the second vent can have more efficient heat dissipation. The windshield (10) of this creation can achieve the effect of reading wind. In the above embodiment, the second vents 112b are exemplified. However, the air hood of the present invention not only defines the above embodiment, but the air hood (10) of the present invention may have more second vents. Ιΐ2 and the opposite plate '130 and each door panel 13Q is also selectively openable or closed to the second 112'; [the airflow inside the air hood 1 can be guided in more ways to achieve effective The effect of heat dissipation. Although the present invention has been disclosed above in the foregoing embodiments, it is intended to limit the creation. In the fine-handed creation of Du County, it is more versatile, all 11 M325722.
