The invention relates to an adjustable ventilation structure applied in a notebook computer with a shell, the shell is provided with a ventilation opening and a driver positioned at one side of the ventilation opening, and the driver is connected with a baffle plate and used for driving the baffle plate to shade, or locally shade, or not to shade the ventilation opening, so as to adjust the opening area and the relative ventilation quantity of the ventilation opening.

A power supply device comprises a shell; the shell is internally provided with a power supply function module; the power module function module is used for converting an external alternating current to different direct currents; the power supply function module also includes a battery charging and discharging control unit; the shell is also provided with a containing groove; the containing groove is selectively provided with a battery or at least one fan; when the containing groove is provided with the battery, the battery is electrically connected to the battery charging and discharging control unit, so that the power supply function module can charge the battery; the battery also supplies power to non-volatile memory through a connecting wire; and when the containing groove is provided with at least one fan, the at least one fan is electrically connected to the power supply function module, so that the power supply function module supplies power to the fan. One rechargeable battery is arranged in the containing groove as an independent power supply for supplying power to several devices, so as to reduce the power supply pressure in supplying power. At the same time, the containing groove can also be provided with the at least one fan, which is used for the heat dissipation of the power supply device or the heat dissipation of the server with the auxiliary power supply device.

The invention relates to a notebook cooler comprising a main cooling board which is provided with two parallelly-arranged cooling exhaust fans, two side cooling boards are arranged on two sides of the main cooling board and hinged to the main cooling board through hinges, and wind incoming fans are arranged on the side cooling board on one side while wind outgoing fans are arranged on the side cooling board on the other side. By the arrangement, cooling of an internal fan of a notebook can be assisted, and sides of the notebook can also be cooled.

The invention discloses a shielding structure of a microwave sensor of a microstrip planar antenna, the upper end of the mounting seat is fixedly connected with a protective cavity, the inner bottom end of the protective cavity is fixedly connected with a plurality of first sliding grooves on the mounting seat, a plurality of balls are rotatably connected to the inside of the plurality of first sliding grooves, The first fix seat is designed, A movable rod and a second telescopic cavity are elastically connected to the inside of the corresponding fixing seat through a first spring, Thus, the microstrip antenna and the microwave antenna with different sizes are effectively fixed, and through the design of the fan, the first air suction port and the second air suction port, the temperature generated by the operation of the internal components of the protective cavity is effectively discharged to the outside of the protective cavity, and the heat dissipation is effectively assisted, so that the device is more safe and practical.

The invention provides a machine case, and aims at effectively solving the problems that an existing machine case is inconvenient to operate and heat dissipation is not good. The machine case comprises a case body, wherein a front panel is flexibly arranged at the front end of the case body in a sliding manner; the front panel comprises a baffle plate and a filter screen; the baffle plate and thefilter screen are fixedly connected through a connection rod; a limiting groove is formed in one side of the connection rod; a first control cabin and a second control cabin are arranged in the side wall of the case body respectively; the first control cabin is internally provided with a first positioning device and the second control cabin is internally provided with a second positioning device;a first cabin door, which is hinged to the outer wall of the case body, is arranged at the outer side of the first control cabin; a second cabin door, which is hinged to the outer wall of the case body, is arranged at the outer side of the first control cabin; a switching device for controlling the first cabin door and the second cabin door to be alternately opened and closed is arranged above thecase body. The machine case provided by the invention is ingenious in structure and novel in concept; different effects are generated through two different sliding distances of the front panel; the requirements of detachable type panels can be met and heat dissipation also can be assisted.
