Abstract
The invention relates to a power supply machine case, and belongs to the technical field of power supply and distribution. The power supply machine case comprises a box body and a panel, the panel is provided with air inlets, an air channel is disposed in the box body, first fish-mouth-like air inducing ports are disposed at positions of the air inlets of the air channel, and two sides of an air outlet of the air channel are provided with a second fish-mouth-like air inducing port and a third fish-mouth-like air inducing port; and an ion wind rod the width of which is equal to the width of the air channel is disposed between the second fish-mouth-like air inducing port and the third fish-mouth-like air inducing port. The power supply machine case can effectively reduce deposition of dust in the power supply machine case, and improve the heat-radiation effect.
Description
Technical field
The present invention relates to a kind of power case, belong to supplying electricity and power distribution technical field.
Background technology
Power case is the very important part of electron trade electronic equipment, the field of electronic components such as transformer, wiring board is installed in power case, so power case requires that body structure is more firm, heat for the ease of producing during electronic devices and components work in casing is drained, and requires that again cabinet has good ventilation and heat performance.
Due to power case not operation under dustless condition, therefore air outlet or air inlet usually can deposit many dusts, make ventilation difficulty cause power case internal temperature to raise, and electronic devices and components are damaged.
Summary of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, proposes a kind of power case utilizing fluid mechanics mode to guide in cabinet to enter dust motion.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of power case, comprise casing and panel, described panel offers air inlet, air channel is provided with in described casing, the air intake vent place in described air channel is provided with the first fish nozzle type air-vent, and the both sides of the air outlet in described air channel are provided with the second fish nozzle type air-vent and the 3rd fish nozzle type air-vent; The ion wind rod wide with described air channel is provided with between described second fish nozzle type air-vent and the 3rd fish nozzle type air-vent.
The improvement of technique scheme is: the air outlet of described first fish nozzle type air-vent is just to the air intake vent in described air channel, the fish mouth of described second fish nozzle type air-vent is positioned at the limit, left side in described air channel, and the fish mouth of described 3rd fish nozzle type air-vent is positioned at the right edge in described air channel.
The invention has the beneficial effects as follows: by installing fish nozzle type air-vent at the air-intake device rear portion of cabinet, guide air intake from duct flows, and utilize the wind-guiding post compressed air stream being arranged on fish mouth mouth, the change in flow simultaneously caused due to fish nozzle type air-vent makes blasting and drives dust quickly through cabinet, when moving to rear portion, air channel, air-flow velocity reduces gradually, dust entrained by air-flow gathers to plasma wind rod, , especially in the middle part of air channel dust excessive inventory cleanly to be processed completely by plasma wind rod, can effectively reduce dust and again proceed to cabinet inside by air channel.Second fish nozzle type air-vent and the 3rd fish nozzle type air-vent secondary accelerate air-flow, drive air-flow velocity, improve radiating effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described;
Fig. 1 is the structural representation of the power case of the embodiment of the present invention.
Embodiment
Embodiment
