New Description: * [New Technology Area] This creation is about a cabinet, and more specifically, a cabinet for providing electronic equipment such as servers. [Prior technology] • Common work such as audio and video, video, monitoring instruments, switches, servers, monthly subscriptions, and power-saving devices are mainly used to make electronic e-boards in the form of stacks or side-by-side. Set in the cabinet, and then in the air-conditioned environment of the appropriate temperature, humidity, etc., so that the inside of the cabinet = sighs stable operation. In the maintenance of the stable operation of the electronic equipment in the cabinet, whether the heat generated by the electronic δ can be effectively dissipated is particularly important because most of the causes of the electronic equipment crash are from the semiconductor components and hard. Overheating of core components such as discs. Therefore, in the case of poor heat dissipation performance, as the operating temperature of the electronic device increases, the phenomenon of unstable operation will inevitably occur, which may cause the occurrence of the machine to reduce the service life of the electronic device. The widely used electronic device format is defined by the American National Standards Institute (ANSI). The structure is roughly composed of a number of motherboards with corresponding functions in the cabinet (such as the fifth bulletin of China's announcement). It is disclosed in the new patents of No. 536U2 and No. 536143, and an air suction device is disposed on the machine side to discharge the working heat source to the outside. The air suction device is arranged at the rear end of the cabinet, and the front end is provided with an air inlet so that the fan of the pumping air 2 can suck the outside cold air from the front end, so that the cold air flows through the heat source for heat exchange. It is then discharged by the back end. According to this structure, 19196 5 M293635 .:::::::: The device has an internal active heat dissipation design, but it must be used for temperature, and: 1: milk for heat exchange, which can effectively reduce its work. Γ "" w The source of air is essentially a semi-open design from the air conditioning environment of the computer room. The cold temple required for its air-conditioning environment: ί, should be from the pre-planned elevated floor i, as the second Γ 'And according to the rules, the place where the cabinet 2 is placed is reserved for opening 11, so that the cold:::Τ=ίΓ11 is taken by the corresponding cabinet 2. The habit is generally composed of a frame peripheral assembly side sealing plate, front and rear doors and top =: ίί ' Both sides of the frame are preset with a number of keyholes for the installation of the door to the right of the book 5 and 3 ° cabinet 2 The sealing plate is reserved corresponding to: top Qiuguang air inlet 21' and another fan 22 is installed on the top sealing plate to draw air from the top # outside. However, the lack of the following cabinets has yet to be improved. Hundreds of first, the opening 11 of the raised floor 1 is introduced into the air inlet of the cabinet 2. The bottom: the flow direction of the cold air inside the cabinet 2, due to the obstruction of the cabinet device 3 and the direction of the intake air The flow of the other, the severe noise of the person and the air intake of the gas 'relatively reduce the efficiency of the convection heat dissipation in the cabinet. The hot and cold air in the cabinet is in direct contact with the heat exchange, resulting in waste of cold air energy. The cold air continues to flow into the machine w due to the operation of the fan 22 at the top of the cabinet 2, and is discharged through the electronic device 3, and then impacts the rear end panel of the cabinet 2 to form a vortex phenomenon in the cabinet to affect the hot air discharge. At the end of the mouth, the work is not sufficient and the average is absorbed by the electronic equipment 3, and most of the cold air tends to be discharged directly from the top 19196 6 M293635. The fan 22 is discharged, so for the real heat source (The semi-conducting body element or the hard disk component in the electronic device does not exert the expected heat exchange effect, and the electronic device 3 located in the center and the bottom portion of the cabinet 2 is thermally transferred due to the heat transfer method. The occurrence of job instability is now a serious phenomenon. Due to the above various factors, the heat dissipation effect of each electronic device 3 is not known to provide a lower temperature air-conditioning environment in the machine room, in order to reduce (the average temperature in the cabinet), but the actual heat generated by this method is obviously not economical. It is more power-consuming, and it is not enough to use a cabinet to overcome the heat dissipation effect in the conventional cabinet. The wrong way is to effectively supply cold air to the electronic port inside the cabinet, and provide a smooth convection path and enough The air volume α Jiang A u A 埶 efficiency, knowing the enthalpy, entering the X t π wind with the convection of the rain convection, the speed of the 々 效果, to provide the active cooling effect to the light internal internal electronic equipment, and the virtual β 丨 double fruit to the branch cabinet... And W Asia's corresponding award level power consumption, each ρ has become a difficult problem to be overcome in the industry. _ [New content 1 In view of the above shortcomings of the prior art, this creation is in a kind The cabinet for electronic equipment, the ◊ lies in the heat generated by the lightning and the side of the ki and the other cabinets in the cabinet, and the heat is generated to the outside world, and the efficiency is improved by the convection effect. Another purpose of this creation is to provide a cabinet for electronic equipment to avoid the lack of hot and cold air directly connected to the standby. The 散热A, 乂 所 导致 导致 散热 散热 散热 散热 散热 散热 散热 散热Μ, kinds of electronic equipment 19196 7 M293635 • cabinet, can provide a smooth convection path. The heat inside. About the wind, 俾 effective escape cabinet broadcast = up to the above and other purposes, the creation provides an electronic device The cabinet used includes the main area of the first area and the body of the second area of the "i" sub-section, the #w domain (four) area is placed at an oblique angle, and the 竽雷+尨窀子 叹 以 疋 疋 ( (4) An air inlet spanning the first and second bodies is disposed in the first area, and is rolled into the first area by the air inlet, and is opened by the The second area is for the flow of the electricity. The second part is subjected to heat exchange and then enters the gas through the exhaust port to be output to the outside. One-or the table, the first: Π: 'The system divides the body into a brother through the baffle And the baffle has at least one opening for enabling the electronic device to straddle the first and second regions=the tooth=, the 擒 plate is a heat insulating plate made of a heat insulating material. Therefore, The creation can be hunted by the baffle to separate the hot and cold air in the cabinet body, so as to avoid cold and hot air direct contact and heat exchange, resulting in low utilization of cold air and poor heat dissipation. The cold air directly rises to the top of the body and directly drains the exhaust gas from the top to eliminate the waste of resources. In addition, in the present creation, the air inlet is opened at the bottom of the body and located in the first area. In the present creation, the exhaust port is located at the top of the body and is located in the second area. 19196 8 .M293635 The search pattern is only inconsistent with the original creation. __ π sinus pw * The 70 pieces of money 'the components of the display are not the only ones that are applied at the same time. The actual real _ non-horse ratio is -selective:; ::? : The number, shape and size of the pieces are complicated. °The juice is also, and the layout of the piece of equipment may be more straightforward — as shown in the second section of the electronic device used in Figure 2::: As shown in the figure, the cabinet of the present invention includes a J body 30 and a cold air inlet and a hot air inlet 31 and an exhaust port 32 respectively provided on the body. In the following, the interior of the main body 30 has a first area 3 〇〇 and a first area 301 ′ connected to the first area, and the inside of the body 3 可供 is available for the plurality of electronic devices 5 at an oblique angle Placement, the electronic device 5 is simultaneously placed across the first region 300 and the second region. In the present invention, the body is divided into the first region 300 and the second region 3〇1 by a support plate 3〇2 disposed therein, and the electronic device 5 is fixed. Tilt the horn and pass through the baffle 302. The baffle 302 may be made of a heat insulating material to prevent hot air in the second region 201 from condensing water droplets therein to flow into the inside of the electronic device 5, resulting in damage of the electronic device 5. The body 30 is generally composed of a frame including four pillars, a side sealing plate assembled on the frame, a top sealing plate, a bottom sealing plate, a front door and a rear door, and is disposed in the frame of the body 30 and the top and bottom. The sealing plate is formed by a baffle 302 which is perpendicular to the front door and the rear door, and the baffle 3 is provided with a plurality of openings through which the electronic device 5 can pass. Pre-δ and multiple keyholes are applied to both sides of the frame according to the specification. Each of the electronic devices 5 is partially located in the first area 3〇〇 19196 10 • M293635 and the other part is located in the first part 300 of the first brother. In the area 301, and the electronic device 5 is located at the bottom of the first area 3〇〇, which is lower than the X air inlet 31 located in the second area 301, for the person*! The intake port 31 flows into the first region_. The exhaust port, 3;: 5 is also at the top of the brother-area 3G1, for the electronic device 5 inside the body 30: the hot air exhausted to the second region 301 is exhausted through the air inlet 32. In the present creation, the top of the body 3〇 corresponds to the exhaust port: f can be provided with an exhaust fan (not shown) to transmit the second region 3gi through the exhaust air m (four) port 32 Hot air is drawn out. 3 picture, the use of the machine for the creation of electronic equipment, the use of sandal. As shown in the figure, it is placed on the elevated S T of the machine room. The pole 1 is set with the air inlet 31 aligned with the opening 11 of the raised floor 1 . The creation air towel; the cold air provided by the air conditioning system of the room flows through the opening 11 and the air inlet 31 into the first area 3〇〇 of the body 30, and the electronic system is placed on the body in a tilting manner. Within 3G, so that the cold air entering through the air inlet 31 at the bottom of the body 3〇 is in the process of rising, part of the cold air is blocked by the portion of the electronic device 5 located in the view of the first region, so that the cold air can The two adjacent upper and lower opposite electronic devices 5=the channel is taken away by the heat generated by the cold air flowing the electronic device 5, and the hot air after the heat is absorbed into the second area 300 The middle and the rear can be discharged to the outside through the exhaust port 32. The cabinet structure of the present invention can increase the amount of cold air flowing through the interior of the electronic device and increase the heat dissipation efficiency by boosting the 19196 11 M293635. In addition, the cold air is converted into hot air by the convective heat exchange in the electronic device 5 and discharged to the second zone: and the rising hot air flow is formed in the first region 3.1 and the gas port 3 2 is discharged to the outer ruler. Therefore, even if the sputum air discharged from the electronic device 5 hits the rear end of the cabinet, it is discharged in the body 30 due to the early _ ^ ”, and the work is disordered. The hot air is inclined: the hot air of the bomb also tends to move upwards, so there are two: empty: discharge 'not easy to form eddy current phenomenon and hinder the hot air to the outside of the body. To discharge to the outside, in this creation, Through the support plate 302, the cold air supplied to the electric backup device 5 is exchanged, and the heat is exchanged, and the electrons 5 and 5 are formed by heat exchange: = heat exchange and cold are avoided by direct contact with hot and cold air. Empty milk does not flow through the electronic device 5 and straight (4) out of the outside world can improve the cold rate of the cold line, avoid energy waste. ... and then in the above, in this creation. Let the hot air along a single and smooth path Circulation (overhead "intake...first area Equipment 5 - the second area 3 〇 "Exhaust port Shanghai sunset phase * door 1 "; without vortex, phenomenon 'thus can form smooth convection and efficient efficiency:: to ensure that electronic equipment 5 The cabinet of the second cabinet and the power of the embodiment are maintained in an efficient and stable working environment. The figure shown in FIG. 4 is a schematic cross-sectional view of an embodiment of the electronic device of the present invention. An embodiment is substantially the same except that the self-contained cabinet includes a guide plate 2 3 . 19196 12 . M293635 - as shown in FIG. 4, the guide plate 23 is first attached to the body 30 In the region 300, the guiding plate 23 is connected to the baffle 302. In the present invention, the guide plate 23 is disposed at the bottom of the body 30 adjacent to the air inlet 31 to flow into the body 30 via the air inlet 31. The cold air inside is guided into the first region, thereby preventing the cold air from being trapped by the electronic device 5 placed at the bottom of the body, thereby making it difficult to enter the air. Therefore, through the creation, sufficient cold air can be supplied to the body. 3〇 Internal electronic equipment 5 for heat dissipation No: If you provide a lower temperature air-conditioning environment in the computer room, you can be more economical and save electricity. This creation 隔离b isolates cold and hot air, and cool air to enhance heat dissipation. The cold and hot air are all singular and circulated, and there is no obstruction such as eddy current. Therefore, it can produce fast f smooth convection and high efficiency heat dissipation. The cold air recombination can be caused by the inclination angle of each electronic sigh. It flows more unobstructed inside the electronic device, and I enhances the heat dissipation effect' and ensures that each t-spot is held in an efficient and stable setting environment. In addition, this creation can guide the position of the air inlet near the body. The board is used to increase the amount of cold air that enters the cabinet body from the outside, and the input 2 can have a heat dissipation effect and a heat dissipation speed. In the end, this creation does not need to provide a lower temperature air conditioning environment in the computer room as well as a second-in-class technology, and is more in line with the effect cup and thus saves electricity. ^ Ibe's knowledge is merely illustrative of the principles of this creation and its ethics': not intended to limit this creation.
