Description

Fan Fixture

[technical field]

The utility model be about a kind of simple in structure, be convenient to dismounting and good fan Fixture is imitated in heat radiation.

[prior art]

Main heating source in the PC is central processing unit (CPU) and the interior power supply unit of computer casing on the host board.Common by installing radiator on the central processing unit (CPU) and on radiator, installing of the heat discharge of the mode of fan with the central processing unit (CPU) generation.In addition, fan also is installed so that the heat of its generation is discharged in the power supply unit.Along with computer industry constantly develops, the high frequency of computer, high-powerly bring new problem to heat radiation again.Therefore, in order to reach better radiating effect, so on computer casing the fan of the independent running of installing, thereby the cooling air of computer casing outside is sucked, and cooperate the fan of power supply unit in computer casing, to produce convection current.By in computer casing, installing a fan Fixture additional, installing and fixing between the mode on this fan Fixture of again fan being fixed on is reached in fan and the computer casing.But the normal screw locking fan that adopts locks fan Fixture on computer casing at fan Fixture and with screw in this means of fixation, brings many inconvenience to assembly and disassembly like this.

Along with the continuous development of technology, the fan fixer of spiral shellization has appearred not having, as the fan fixer of No. 01201836.8 announcement of Chinese patent application.This fan fixer comprises a fan board, this fan board is fixed on the wall of computer case, fixed installation one fan on this fan board, this fan board protrudes out a grab respectively towards a side of wall of computer case, on top frame is set the position tongue piece, protrudes out a catch and little hook and big hook at this fan board respectively towards a side of fan, and the left and right lateral margin of the fan frame of fan is stuck between the catch, the lower lip of fan frame is held by this little hook, and last lateral margin is then blocked by this big hook.This fan fixer holds this fan by large and small hook and catch, makes the complex structure of this fan fixer.In addition, this fan is the outside of device at this fan board, and this fan is failed to fit tightly in this wall of computer case but the thickness of this fan board and blowing at interval, makes that radiating effect is not fine.

[summary of the invention]

The purpose of this utility model be to provide a kind of simple in structure, be convenient to dismounting and good fan Fixture is imitated in heat radiation.

Of the present utility modelly be used for fixing a fan and be installed on the computer casing, comprise a main part, one roof, one diapire and two side, this roof and this diapire are that one group of relative rim from this main part extends to form, this two side is that another is organized relative rim and extends to form from this main part, this fan Fixture forms a containing space, respectively establish a fixed hole for four jiaos of this fan, this main part is convexly equipped with some to flexible fastening pin that should the fan fixed hole, the exterior rim of this roof and diapire forms one first clasp and one second clasp respectively, this sidewall extends to form a press part to the roof direction, the front end of this press part is convexly equipped with a make-up piece, this computer casing is established a ventilation porose area, this ventilation porose area periphery is corresponding to be provided with the button hole that can interlock and hold with the clasp and the button piece of this fan Fixture, and this fan is to be fixed in the containing space of this fan Fixture and can to fit tightly on this computer casing.

The utility model fan Fixture adopts no screw structure that fan is fixed on fan Fixture and organizes and is located on the computer casing, and is not only simple in structure but also assembly and disassembly is convenient.In addition, this fan Fixture can make this fan fit tightly in this computer casing and blow, and makes radiating effect better.
