[Technical field to which the device belongs]

  The present invention provides a power supply device suitable for supplying power to a computer and its peripheral devices. Regarding the table

[0002]

[Prior art]

  In the currently mainstream computer devices, the CPU speed reaches 2.0 GHz, Also, the rotation speed of devices such as CD-R and DVD-R is 16 to 56 times that of the old model. In order to meet the demands of the CPU and each disk drive, Power must be supplied more efficiently.   The computer also includes a keyboard, internal modem, network card, and Peripheral devices such as adapter, digital board, mouse and speaker are required. Each peripheral device is also supplied with power via the bus, and an integrated computer In that case, you have to supply power to the monitor and printer.   Therefore, the power consumption of computers tends to increase significantly, and with that increase, Since the amount of heat generated by this increases, it is necessary to install many fans to radiate heat. As a result, the power consumption is further increased.

[0003]   However, a computer is necessary for a standard power supply of about 250 W. Since it cannot supply the required amount of power, as shown in Fig. 1, two standard Type power feeders P1 and P2 can be placed one on top of the other by stacking them vertically, as shown in FIG. As described above, one case is divided into two sections on the left and right, and the feeders B1 and B2 are provided in each section. The ones that have been installed are used.   However, just installing two feeders in this way would increase the volume. It takes up a lot of space, which makes it difficult to install it in the limited space of a computer. Also, the cost is more than doubled because it is necessary to connect the circuit via another connector. Will end up.

[0004]

[Problems to be solved by the device]

  The object of the present invention is to increase the output even if the output is increased according to the increase in power consumption. To provide a power supply device capable of responding to an increase in heat quantity and suppressing an increase in volume and cost. And in.

[0005]

[Means for Solving the Problems]

  The power supply device of the present invention has a case that covers the surroundings and is exposed to the outside of the case. Installed inside the case and plug that can be connected to an external power source. The current introduced from the external power supply via the Installed on the electric circuit and the top surface of the case, cool air drawn from the outside An electric intake fan that blows on the air circuit and a case installed on the back of the case. And an electric exhaust fan that exhausts the heat inside By operating the fans at the same time, the air flows from the outside to the inside of the case, It forms an air flow that passes through the electric circuit and reaches the outside again.   The cool air outside the case is blown into the electric circuit, and the heat generated in the electric circuit warms it up. The trapped air is discharged to the outside of the case through the back surface, so that heat can be dissipated efficiently. It

[0006]   An outlet that can connect the computer body to peripheral devices or extension cords The plug is installed side by side with the plug and is exposed to the outside of the case. A switch that opens and closes with an electric circuit in conjunction with ON / OFF of the computer body. Switch, the switch closes when the computer is turned on, Power is supplied to the computer main body and peripheral devices or extension cords through the outlet. When the computer is turned off, the switch opens and the Power to the computer and peripherals or extension cords via the Is also good.   Simply turn the computer on and off to connect to the outlet. Power supply to all peripherals or extension cords can be automatically switched.

[0007]   Install another intake fan on the front of the case that sucks in the air outside the case. Is also possible.   With this configuration, it flows in through the top and front of the case and through the back. Since the airflow that flows out of the case is generated, heat can be discharged more efficiently. Wear.   At this time, another intake fan is activated when the intake fan and exhaust fan are activated. It can be rotated by the generated airflow.

[0008]

[Embodiment of device]

  As shown in FIGS. 3 and 4, the power supply device of the present invention includes a main body 1 and a cover for covering the main body 1. A case 10 including a bar 2 is provided.   The main body 1 is formed by forming standing walls 6 and 7 at the front and rear ends of the bottom plate 5, respectively. An electric circuit 12 is disposed on the upper surface of the.   In addition, the electric circuit 12 includes a plug 11 connectable to an external power source and a connector (not shown). An outlet that can connect the computer to the peripheral device 3 or extension cord 4 (Fig. 7) 16, the plug 11 and the outlet 16 are connected to the main body 1 as shown in FIG. It is attached to the rear standing wall 7 and is exposed on the back surface.   Then, the current introduced from the external power source through the plug 11 causes the electric circuit 12 to flow. After being rectified and stepped down through Power is supplied to the container 3 or the extension cord 4.

[0009]   As shown in FIGS. 3 and 4, the cover 2 has a hanging wall on each side end of the top plate 8. 9 to form the top surface and both side surfaces of the case 10.   Further, above the electric circuit 12, the top plate 8 of the cover 2 has an electric intake fan. 21 is installed, and by operating this intake fan 21, Cold air is taken in and blown onto the electric circuit 12.   In this embodiment, two intake fans 21 are installed. The number of 1's can be appropriately changed according to the installation area of the electric circuit 12 and the like.

[0010]   In order to form an air flow with a high cooling effect, an electric discharge is provided on the standing wall 7 at the rear of the main body 1. The air fan 13 is installed and operates the exhaust fan 13 in conjunction with the intake fan 21. This allows the heat generated in the electric circuit 12 to be discharged to the outside of the case 10. ing.   Further, another intake fan 14 is installed on the standing wall 6 at the front of the main body 1. Other sucking The air fan 14 operates in conjunction with the intake fan 21 and the exhaust fan 13, and The cold air outside 10 is sucked in.

[0011]   As a result, as shown in FIG. 5, the top surface and the front surface of the case 10 are passed through from the outside. Air that flows in through the electric circuit 12, and then flows out again through the rear surface. Flow is formed, and the heat generated in the electric circuit 12 is very efficiently outside the case 10. Is discharged to the department.   The other intake fan 14 may be electrically driven, but the intake fan 14 is The fan 21 and the exhaust fan 13 are rotated by the air flow generated when they are operated. You can also do it.

[0012]   As shown in FIG. 7, between the electric circuit 12 and the outlet 16, an outlet 1 Switch 1 that opens and closes in conjunction with ON / OFF of the computer body connected to 6. 5 is interposed.   When the computer body connected to the outlet 16 is turned on, the switch 15 When closed, the electric current taken in from the plug 11 is transferred to the computer main body and the controller. Power to the peripheral device 3 such as a monitor or printer connected to the printer 16 or the extension cord 4. To be done.   On the other hand, when the computer is off, the switch 15 opens and The power supply to the computer main body, the peripheral device 3 or the extension cord 4 is stopped.

[0013]

[Effect of device]

  According to the invention of claim 1, cold air outside the case is blown to the electric circuit, Air warmed by the heat generated in the electric circuit is discharged to the outside of the case through the back surface. Therefore, the heat dissipation efficiency is high, and therefore the output should be increased as the power consumption increases. Can cope with the increased heat generation by this, and the power can be supplied like the conventional one. Since it is not necessary to use two containers, an increase in cost and space can be suppressed.   According to the invention according to claim 2, the switch is interlocked with ON / OFF of the computer main body. By opening and closing the switch, you can connect to peripheral devices or extension cords via outlets. Since the power supply is automatically switched, it is necessary to turn on / off the power of each peripheral device one by one. No need. In addition, because the power supply to the computer and peripheral devices is concentrated, Improves computer stability.
