Below in conjunction with drawings and Examples, the invention will be further described.
See Fig. 1-Fig. 2, the gas-liquid separated heat dissipation wind channel structure of this air conditioner outdoor unit electric control box, off-premises station is by shell 2, base plate 10 and off-premises station panel 14 surround, electric-controlled box sets within it in chamber 15, described electric-controlled box comprises electric-controlled box housing 3, cover the electric-controlled box cover plate 11 connect thereon, and the automatically controlled device 7 arranged in the relative closure space 16 of both formation, the front of its electric-controlled box housing 3 is open surface, electric-controlled box cover plate 11 lid connects thereon, electric-controlled box housing 3 at least left and right one side top be provided with through hole A3a, the top, the left and right sides of the present embodiment electric-controlled box housing 3 is provided with through hole A3a, the bottom of electric-controlled box cover plate 11 is provided with through hole B11a, through hole B11a is provided with gas-liquid separation mechanism, and on off-premises station panel 14, the position of corresponding through hole B11a is provided with louvre ventilation mouth 14a, and through hole A3a and through hole B11a forms convection current air channel.
Through hole A3a is provided with screen pack A5, through hole A3a covers by screen pack A5 completely.Automatically controlled box body 3 outside is also provided with the rain-proof cover 4 can blocking through hole A3a, and through hole A3a covers by rain-proof cover 4 completely.
Gas-liquid separation mechanism is the gas-liquid separation plate 8 be arranged on inside electric-controlled box cover plate 11, and gas-liquid separation plate 8 covers through hole B11a.Gas-liquid separation plate 8 at least left and right one side on be provided with through hole C8a, enterprise's separating plate 8 left and right sides of the present embodiment is provided with through hole C8a, and through hole C8a is provided with screen pack B9, through hole C8a covers by screen pack B9 completely.
Through hole B11a is provided with screen pack C13, through hole B11a covers by screen pack C13 completely.Airduct 12 is provided with between through hole B11a and louvre ventilation mouth 14a.
The position of the corresponding through hole B11a in bottom of electric-controlled box housing 3 is provided with osculum A3b, and on base plate 10, the position of corresponding osculum A3b is provided with osculum B10a.
Wherein, the inner chamber 15 of off-premises station is also provided with blower fan 1, heat exchanger 6 and compressor 17, and blower fan 1 is arranged on the top of shell 2, and heat exchanger 6 is arranged on the sidepiece of shell 2, and compressor 17 is arranged on base plate 10, and automatically controlled device 7 is vertically arranged on electric-controlled box housing 3.
Louvre ventilation mouth 14a of the present invention, airduct 12, through hole B11a, gas-liquid separation plate 8, through hole C8a and through hole A3a form a complete convection current air channel under the effect of blower fan 1, its to the radiating principle of electric-controlled box as following:
Blower fan 1 is power source, negative pressure is produced when its work, the louvre ventilation mouth 14a of the normal temperature air of off-premises station outside outdoor on machine side plate 14 is entered, and flow through whole passage successively, heat in the relative closure space 16 form electric-controlled box housing 3 and electric-controlled box cover plate 11 is derived, under ensureing that automatically controlled device 7 is operated in a good temperature environment, the flow direction of this air-flow, as shown in the dotted arrow in figure.And in the outdoor air of rainy weather etc., humidity is comparatively large, raindrop, water smoke etc. will be mingled with, if allow such mixing air directly flow through electric-controlled box inside, must for causing getting wet (short circuit) and damaging of automatically controlled device 7.Convection current air channel in the present invention is radiating airflow passage, and circulation path, through well-designed, ensure that moisture can not directly contact with automatically controlled device 7, also has multiple gas-liquid separation mechanism in whole passage, ensures that automatically controlled device 7 can not be infected with water smoke or water droplet.
Louvre ventilation mouth 14a essence on off-premises station panel 14 is the first heavy gas-liquid separation device, and larger raindrop can be blocked in the outside of air-conditioner outdoor unit by it.
The water smoke that air after louvre ventilation mouth 14a can carry larger particles enters airduct 12, by arriving the through hole B11a on electric-controlled box cover plate 11 after airduct 12, the screen pack C13 essence that on through hole B11a, place installs is the second heavy gas-liquid separation device, screen pack C13 has less hole, material is water wetted material simultaneously, and air-flow is cut down through its rear section water smoke.
Then air-flow enters the interconnection that gas-liquid separation plate 8 is formed with electric-controlled box cover plate 11, this interconnection essence is triple gas-liquid separation device, airduct 12 and this interconnection form T-shaped structure, at infall air-flow and gas-liquid separation plate 8 vertical direction toward impact, the material of gas-liquid separation plate 8 is similarly water wetted material, in this knockout process, a large amount of water smoke is separated again, forms water droplet and deposits to the bottom of interconnection.
After clashing into, air-flow is broken down into symmetrical two-way, and left and right two-way air-flow can continue contact with gas-liquid separation plate 8 and analyse into water droplet in the process flowing through passage.Then air-flow arrives the through hole C8a on gas-liquid separation plate about 8 two sides, and the screen pack B9 essence that through hole C8a installs is quadruple gas-liquid separation device, and its operation principle is consistent with screen pack C13.
After this quadruple gas-liquid separation device, air-flow just finally arrives the relative closure space 16 of electric-controlled box, does not at this moment almost have water smoke in air-flow, is the air-flow of drying.Meanwhile, the air-flow entering this relative closure space 16 is not directly blow to automatically controlled device 7, but two, the left and right wall flow of laminating electric-controlled box housing 3, finally from left and right, the through hole A3a in top portion, two sides discharges.
Said flow can cause two convection current whirlpools in the relative closure space 16 at electric-controlled box when laminating two wall flow, fully carries out heat exchange and take away heat with automatically controlled device 7.The water droplet simultaneously having only a few is separated out in the screen pack A5 of two sides, and water droplet will be discharged on the inner chamber 15 of off-premises station.
In addition, the water droplet that quadruple gas-liquid separation device noted earlier is separated out flow to osculum A3b under gravity and is discharged on the inner chamber 15 of off-premises station, is more finally discharged to the outside of air-conditioner outdoor unit by the osculum B10a of outdoor unit base 10.Therefore, can efficiently solve the heat radiation of automatically controlled device 7 and a difficult problem for waterproof, its radiating effect is remarkable, guarantees that complete machine is safe and reliable to operation simultaneously.
